Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943.  
In 1967, Tasmania experienced a drought（干旱）. The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.
Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals（節(jié)日）. For example, in 1992, Tasmania extended（延長(zhǎng)）daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games.
The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television.

Pushy parents and teachers who “hothouse” the under-5s risk causing damage to the children’s long term development, a leading education expert said.
Lilian Katz, Professor of Education at the University of Illinois, said that four-year-olds engaged in reading and writing went on to perform worse academiclly than those engaged in imaginative learning. They scored higher in tests at the age of 5, but children whose first year at school was stimulating outstripped them four years later.
The findings suggest that the government's structured approach to early years' learning could be storing up problems for children. They also raise serious questions about the plan for all children to be able to read by the age of 6.
In many countries formal teaching does not start until children are 6 or 7 and have improved their social and manual skills. Children start learning to read and write at 6 in the United States. France and Germany , and at 7 in Finland and Sweden.
Professor Katz said that in many schools the courses were "boring children to tears". Much academic teaching required children to learn by memorizing pieces of information out of context, she said. Teaching in reception class should instead allow children to develop their intellect by exploring their environments and asking questions.
"Research suggests the benefits of formal academic insturction for four- and five-year-olds seem to be promising when they are tested early, but considerably less so in the long term. When these children are followed over a period of three or more years, those who had early experience in more intellectually engaging curricula were more likely to do well in school than their peers, who had received early academic instruction." She avocates teaching children through first-hand experience and play, in mixed-aged classes. This can include puppet shows, drawing or running a pretend shop in the classroom.
1．According to the passage, those who “hothouse” the under-5s would probably _________.
A. prefer a lot of interaction and stimulation while teaching
B. teach in a lively way to motivate kids’ interest
C. push the kids to memorize pieces of information
D. care about the kids’ physical development
2．What does the underlined word “ outstripped” in Paragraph 2 mean?
A. did better than                               B. looked down upon
C. caught up with                                      D. performed worse than
3．According to Lilian Katz, the government’s structured approach to early-years learning ______.
A. is necessary for improving children’s reading and writing ability
B. needs to be improved to develop children’s academicability
C. will cause problems to children in their future learning
D. has more advantages than disadvantages
4．The message the author wants to deliver through the passage is that formal teaching _______.
A. can start at different times in different countries.
B. should not be started too early
C. is best carried out in Finland and Sweden
D. should include teaching children social and manual skills
5．Which of the following is NOT the opinion of Lilian Katz?
A. Children should be taught through first-hand experience.
B. Learning in a mixed-age class is good for children.
C. Running a shop can help children get good marks.
D. Puppet shows and drawing are useful easy in teaching children.

It seems that some people go out of their way to get into trouble. That’s more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty.
“I was on the way to a personal-injury accident in West Nashville. As I got onto Highway 40, blue lights and sirens（警笛）going, I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway. The driver somehow panicked at the sight of me. He was going more than a hundred miles an hour and began passing cars on the shoulder.”
But Hyde couldn’t go after him. Taking care of injured people is always more important than worrying about speeders, so the officer had to stay on his way to the accident. But he did try to keep the Firebird in sight as he drove, hoping another nearby unit would be able to step in and stop the speeding car. As it turned out, keeping the Firebird in sight was not that difficult. Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.
Hyde followed the Pontiac all the way to his destination （目的地）. At that point he found another unit had already arrived at the accident scene. His help wasn’t needed. Now he was free to try to stop the driver of the Firebird, who by this time had developed something new to panic about.
“Just about that time,” Hyde says, “I saw fire coming out from under that car, with blue smoke and oil going everywhere. He’d blown his engine. Now he had to stop.”
“After I arrested him, I asked him why he was running. He told me he didn’t have a driver’s license（執(zhí)照）.”
That accident cost the driver of the Firebird plenty － a thousand dollars for the new engine－ not to mention the charges for driving without a license, attempting to run away, and dangerous driving.
63. The meaning of “panicked” in Paragraph 2 is related to _____.
A. shame B. hate    C. anger  D. fear
64. Why did the driver of the Firebird suddenly speed down the highway?
A. Because he was racing with another driver on the road.
B. Because he realized he had to hurry to the accident scene.
C. Because he thought the police officer wanted to stop him.
D. Because he wanted to overtake other cars on the shoulder.
65. Which of the following statements is true?
A. Someone else was taking care of the injured person.
B. The Pontiac reached its destination at the accident scene.
C. Hyde knew where he was going by following the right car.
D. The policeman was running after a speeder on Highway 40.
66. The driver of the Firebird ______.
A. took a wrong turn on the way
B. had some trouble with his car
C. was stopped by the police officer
D. paid for the expenses of the accident
67. What is probably the best title for the article?
A. Losing His Way?   B. Going My Way?
C. Fun All the Way?   D. Help on the Way?

These days we hear a lot about how air pollution is changing temperatures on the earth. New evidence from a mountaintop in China now suggests that pollution can also change the amount of rain and snow that falls in some places.
Usually, more rain falls in mountainous places than in flat areas upwind from the mountains. That’s because air can hold a lot of water. When wind blows wet air up a mountainside, the air gets colder. This temperature change often forces water to fall as rain or snow.
In recent years, however, many mountainous areas in the western United States have been getting less rain than normal. Mountains that are downwind from cities have experienced the biggest drops.
Some scientists have theorized（推理）that pollution drifts （趨勢(shì)）from the cities into the mountains, affecting rainfall, but proving this link has been difficult.
Searching for answers, a team led by a scientist from the Hebrew University went to s mountain in China called Mount Hua, which is 2,060 meters tall and lies about 120 kilometers east of the Chinese city Xi’an. Since 1954, scientists have been collecting details about rainfall, humidity（濕度）, and visibility（能見度）in the area.
Using this data, the scientists compared rainfall on Mount Hua to rainfall in the nearest city, Huayin, on days with different levels of visibility. When the air was clear and people could see as far as 20 km, the scientists found that 65% more rain fell on the mountain than in the city.
But when the air was smoggy, allowing only 8 km of visibility through the mist, the mountain received just 20% more rain than the city. The new data supports the theory that pollution affects rainfall.
Some scientists believe that there are other explanations for the numbers. It’s possible, for example, that natural particles（微粒）in the air, rather than particles produced by pollution, are affecting visibility.
小題1:According to the 1st paragraph, air pollution is changing the following EXCEPT ______.
A．the temperature B．the amount of rain
C．the habit of eatingD．the amount of snow
小題2:According to the passage, what will probably happen when the wet air in the sky gets colder?
A．It will probably rain or snowB．It will probably be cloudy.
C．It will probably windD．It will probably become dry.
小題3:Why did the team led by a scientist go to Mount Hua?
A．They wanted to pay a visit to Mount Hua.
B．They wanted to collect the data for their theory.
C．They wanted to measure Mount Hua.
D．They wanted to have a good rest on Mount Hua.
小題4:You can most probably read the passage in _______.

A small town in southwest Britain is banning(禁止) plastic bags in an attempt to help the environment and cut waste—a step that environmentalists believe is a first for Europe.
Shopkeepers in Modbury population 1500,agreed to stop handing out disposable plastic bags to customers on Saturday.They said paper sacks and cloth carrier bags would be offered instead.
Last month,San Franciso became the first U.S. city to ban plastic grocery bags.Internationally,laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland,where governments either tax shoppers who use them or fine companies that hand them out.Bangladesh already bans them,and so do at least 30 remote Alaskan villages.
Modbury,about 225 miles southwest of London,has also declared a bag amnesty(寬限期),allowing local people to hand in plastic bags that have piled up at home.They will be sent for traveling.
The Modbury ban was the idea of Rebecca Hosking,who saw the effect of bags on marine life while working in the Pacific as a wildlife camerawoman.She said response(反應(yīng)) in the town so far had been “really positive”.
“Modbury is quite an old-fashioned town and a lot of people have wicker baskets to go out shopping anyway,”Hosking told Sky News Television.
The Worldwatch Institute,an environmental research agency,states that 100 billion plastic bags are thrown away each year in the United States alone.More than 500 billion are used yearly around the world.
小題1:What was Rebecca Hosking?
A．A lawyer.B．An environmentalist.
C．A sailor.D．A photographer.
小題2:The underlined word “disposable” in the passage probably means _______.
A．a(chǎn)cceptableB．valuable
C．throw-awayD．long-lasting
小題3:It can be inferred from the passage that _______.
A．most of the people in Modbury continue to use plastic bags
B．fewer and fewer plastic bags will be used in the world
C．San Francisco is the first city to ban plastic bags in the world
D．most countries in the world have passed laws to ban plastic bags
小題4:Which of the following would be the best title of the passage?
A．Environmental Protection
B．Big Cities Banning Plastic Bags
C．Effect of Plastic Bags on Sea Animals
D．British Town Banning Plastic Bags

The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q., a generally bad predictor of success. Instead, it’s purposeful practice. Top performers spend more hours practising their craft. It you wanted to picture how a typical genius might develop, you’d take a girl who possessed a slightly above average language ability. It wouldn’t have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.
This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating circle who might someday join. It would also help if one of her parents died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She’s be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, he delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback, viewing her performance form the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems—how do I get characters into a room—dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It’s the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we’re “hard-wired” to do. And it’s true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.
小題1:The passage mainly deals with________.
A．the function of I.Q. in cultivating a writer
B．the relationship between genius and success
C．the decisive factor in making a genius
D．the way of gaining some sense of distinction
小題2:By reading novels and writers’ stories, the girl could________.
A．come to understand the inner structure of writing
B．join a fascinating circle of writers someday
C．share with a novelist her likes and dislikes
D．learn from the living examples to establish a sense of security
小題3:In the girl’s long painstaking training process, ________.
A．her adviser forms a primary challenging force to her success.
B．her writing turns into an automatic pattern of performance
C．she acquires the magic of some great achievement
D．she comes to realize she is “hard-wired” to write
小題4:What can be concluded from the passage?
A．A fuelling ambition plays a leading role in one’s success
B．A responsible adviser is more important than the knowledge of writing.
C．As to the growth of a genius, I.Q. Doesn’t matter, but just his|her effort.
D．What really matters is what you do rather then who you are.

There is one difference between the sexes on which every expert and study agrees: men are more aggressive than women. It shows up in 2-year-olds. It continues through school days and persists into adulthood. It is even constant across cultures. And there is little doubt that it is rooted in biology.
If there's a woman’s trait(特點(diǎn)) which is the same as men’s aggressiveness, it's what social scientists refer to as the result of "education". Feminists have argued that the caring nature of women is not biological in origin, but rather has been forced into women by a society that wanted to keep them in the home. But the signs that it is at least partly inborn are too numerous to ignore. Just as tiny infant girls respond more readily to human faces, female toddlers(學(xué)步者) learn much faster than males how to pick up nonverbal cues（非言語(yǔ)暗示） from others. And grown women are far more skilful than men at interpreting facial expressions: A recent study by University of Pennsylvania brain researcher Ruben Gur showed that they easily read emotions such as anger, sadness and fear. The only such emotion men could pick up was disgust.
　 What difference do such differences make in the real world? Among other things, women appear to be somewhat less competitive--or at least competitive in different ways--than men. At the Harvard Law School, for instance, female students enter with qualities just as outstanding as those of their male peers. But they don' t qualify for the well-known Law Review in proper numbers, a fact some school officials owe to women' s discomfort in the incredibly competitive atmosphere.
　　Students of management styles have found fewer differences than they expected between men and women who reach leadership positions, perhaps because many successful women deliberately imitate men. But an analysis by Purdue social psychologist Alice Eagly of 166 studies of leadership style did find one difference: Men tend to be more “autocratic”-making decisions on their own--while women tend to consult colleagues more often.  Studies of behavior in small groups turn up even more differences. Men will typically dominate the discussion, says University of Toronto psychologist Kenneth Dion, spending more time talking and less time listening.
小題1:The passage mainly discusses__________.
　          
A．how sex differences are demonstrated in social relations
　　		B．how hormone determines sex differences
　　		C．why there are differences between males and females
　　		D．why men and women have different social roles
小題2:Which of the following is true of women's nurturing nature according to the passage?
A．It is not inborn in any sense.
B．It is inspired by women’s families.
C．It is caused by social prejudice.
D．It is partly biological in origin.
小題3:The Harvard Law School example in paragraph 3 suggests that_________.
A．women are not as competitive as men
B．law is not the fight profession for women
C．women are as excellent as men when they are young
D．a(chǎn)cademic qualities are not equal to performance
小題4:Which of the following statement is true according to paragraph 4?
A．Men leaders should consult colleagues and subordinates more often.
B．Female leaders' success is due to their imitating male leaders.
C．Men and women are different in their leadership style.
D．Decisiveness is an important quality for a successful politician.

Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK.
The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter(傳話器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”
Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.
Existing pedometers （計(jì)步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
小題1:According to Swan, the purpose of her design project is to ________.
A．keep a record of the steps of the wearer
B．deal with overweight among teenagers
C．enable children to resist the temptation of TV
D．prevent children from being tricked by TV programs
小題2:Which of the following is true of Square Eyes shoes?
A．They regulate a child’s evening TV viewing time.
B．They determine a child’s daily pocket money.
C．They have raised the hot issue of overweight.
D．They contain information of the receiver.
小題3:What is stressed（強(qiáng)調(diào)）by health experts in their suggestion?
A．The exact number of steps to be taken.
B．The precise number of hours spent on TV.
C．The proper amount of daily exercise and TV time.
D．The way of changing steps into TV watching time.
小題4:Compared with other similar products, the new design ________.
A．makes it difficult for lazy teenagers to cheat
B．counts the wearer’s steps through shaking
C．records the sudden movement of the wearer
D．sends teenagers’ health data to the receiver
小題5:Which of the following would be the best title for the text?
A．Smart Shoes Decide on Television Time
B．Smart Shoes Guarantee More Exercise
C．Smart Shoes Measure Time of Exercise
D．Smart Shoes Stop Childhood Overweight

Some kids can't sit still for long. They have a hard time paying attention to just one thing. They're easily distracted(分神).They can get very impatient. They hate standing in line or waiting for their turn in a game or activity. They get bored pretty fast. They may also be impulsive—saying the first thing that comes to mind or interrupting someone else who's talking.?
For certain kids, this problem is so severe(嚴(yán)重) that doctors have a name for it: attention deficit hyperactivity disorder, or ADHD. Perhaps as many as 1 out of every 20 kids under the age of 18 have characteristics of ADHD. Often, these kids have trouble getting through school and face other difficulties later in life.?
Rizzo started developing the Virtual Classroom in 1999.He wanted to see if he could use it as a tool for testing and treating kids who have attention disorders.?
To diagnose(診斷) ADHD, doctors typically test patients by giving them tasks that require attention. As part of one classic test, you watch letters flashed on a computer screen. Every time you see the letter “A” followed by the letter “X”,you have to press the space bar. If you're paying close attention, you'll register all the times this combination occurs. If not, you'll miss some.?
The Virtual Classroom makes these tests more efficient, Rizzo says. In one experiment, he gave a group of kids the classic “A-X” test. Instead of looking at a computer screen in a doctor's office, though, the kids wore headsets that made it look like they were taking the test in a classroom.?
“Basically what we found,”Rizzo says,“is that, in 20 minutes of testing with virtual reality,?we? replicated(復(fù)制) a finding that usually requires a couple hours of standard testing with computer screens in the psychologist's office.”?
小題1:The first paragraph mainly tells us _______.?
A．how to find a patient with ADHD?
B．the behavior of some kids with ADHD?
C．kids with ADHD cannot sit still for a long time?
D．kids with ADHD are easily distracted
小題2: Perhaps as many as _______ kids have characteristics of ADHD. ?
A. one out of every twenty kids
B. five percent kids less than 18 years old?
C. one out of twenty kids at the age of 18
D. five percent kids more than age of 18
小題3: In the experiment, patients need to press the space bar, when _______.
A．see letters A following XB．first see A then see B?
C．see letter X and AD．see letters A followed by X
小題4:The main idea of the last paragraph is _______.
A．in virtual classroom, we finish the test in 20 minutes?
B．the standard test with computer screen usually costs several hours?
C．the experiment is easy to do?
D．the result of the experiment
