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

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）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.
小題1:Daylight Saving Time was introduced in Tasmania _______________.
A．to stop the drought in 1967B．to support government officials
C．to pass a special law in the stateD．to save water and electricity
小題2: According to the text, which state was the last to use DST?
A．Victoria.B．Queensland.
C．South Australia.D．New South Wales.
小題3: What can we learn about DST in some Australian states?
A．It doesn’t have fixed dates.B．It is not used in festivals.
C．Its plan was changed in 2000.D．It lasts for two weeks.
小題4: What do we know about the use of DST from the last paragraph?
A．There exist some undesirable effects.B．It helps little to save energy.
C．It brings about longer working days.D．Radio and TV programs become different.

So much to do, so little time．So much information, so little time to read ．In this age there is more information than ever before．There is not enough time to read everything we want to read．However, you can take in and understand more information in shorter time through speed-reading．This article will not make you read 3 000 words per minute, but it will show you how to increase your speed greatly．You will also learn the basic techniques of speed reading, along with the dos and don'ts of speed-reading．
When you first learned to read, you would say the word out loud and sound it out．Then you might whisper the word because people can become annoyed when you read aloud．The stage you are now at is saying the word in your head．Most people tend to read this way．Saying the word in your head will cut your reading speed tremendously (極大的)．
How do you calculate your reading speed? The speed is measured by how many words per minute you can read．Get some reading material, preferably a book．Find out how many words are on the page．Time yourself one minute．Start your timer and start reading．When the timer sounds, stop at once．If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute．
The first thing about speed-reading is looking at the word and recognizing it．Don't say the word in your mind, just look at it and recognize its appearance．Later you will recognize groups of four words or more to increase your speed．This is the first and most important step in speed-reading．
The next step is technique．As with any other skill, speed-reading requires technique．You should first be sitting up straight with your book on a horizontal (水平的) surface, such as a table or desk．Next, should be able to see the entire page．This is necessary if you want to recognize clumps of words．Lastly, you should be focused．It's hard to read a lot of noise．Find a quiet place to read．This will help your understand of the text．You need something to guide your eyes while reading．Then right, you should use your hand, Remember when you were little, you would read using your finger．That is a great technique, only now you're using your hand to underline each line．Move your finger smoothly across page．No need to go rush , start our slow．Keep your eyes focused on words as you recognize them while using your hand as a guide．This will increase you speed．
The third step is practice．Practice makes perfect．Set time intervals(間歇)．Read using different techniques, but make sure you understand what you're reading．
小題1:Which of the following statements is true according to the text?
A．Now there is limited information than ever before．
B．Now conditions ask people to use less time to know more information．
C．Now people can read what they like．
D．The less you read, the more time you will spend．
小題2:What is the subject discussed in the text?
A．What speed-reading is．
B．Why we need speed-reading．
C．Now it is much information time．
D．People should practice speed-reading in different kinds of ways．
小題3:Which of the following shows the right way for the speed-reading from the text?
a．Ask for some techniques．
b．Look at many words and recognize them．
c．Practice more．
A．c,a,bB．c,b,aC．b,a,cD．a,c,b
小題4:The underlined sentence“you should be focused”in the fifth paragraph means that _________．
A．a person should devote his attention to it while reading

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air， water and sunlight. Animals and man cannot make food from air， water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you， you will find that there are two kinds of plants： flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two， three or four， and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.
62.小題1:The main idea of the first paragraph is that ______.
A．plants are important for lifeB．plants cannot grow without air
C．there are many plants in the worldD．we can not live without water
63.小題2:What can we infer（推斷） from the passage ？
A．Of all living things animals are most.B．Spores are seeds.

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son, suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut,” Joanna noted.?
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up(蜷伏) with me on the soft and talk,” said Mark.“Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a young lady. The problem is figuring out which time is which.”?
Before age 11, children like to tell their parents what's on their minds.“In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers?.“This completely changes during the teen years.” Riera explained.“They talk to their friends first, then maybe their teachers, and their parents last.”?
Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young.?Another? thing parents should remember is that to be friend, not a manager, with their children is a better way to know them.

In a natural disaster—a hurricane,flood,tornado,volcanic eruption,or other calamity—minutes and even seconds of warning can be the difference between life and death.Because of this,scientists and government officials are working to use the latest technological advances to predict when and where disasters will happen.They are also studying how best to analyze and communicate this information once it is obtained.The goal is to put technology to effective use in saving lives and property when nature unleashes its power with devastating results.
On September 29,1998,Hurricane Georges made landfall in Biloxi,Mississippi,after devastating Haiti,the Dominican Republic,Puerto Rico,and several islands of the Caribbean with torrential rains and winds up to 160 km/h （100 mph）.Few people lost their lives along the Gulf Coast of the United States,although hundreds died in the Caribbean.
This was a very different outcome from 1900,when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston,Texas,killing at least 6 000 people.Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century—residents of Galveston had no advance warning that a storm was approaching,while residents of Biloxi had been warned days in advance of Georges’s approach,allowing for extensive safety precautions.
At the same time that people in Biloxi were thankful for the advance warning,some residents of New Orleans,Louisiana,120 km to the west,were less satisfied.A day before Georges made landfall,forecasters were predicting that the hurricane had a good chance of striking New Orleans.Because much of New Orleans lies below sea level,the city is at risk for flooding.In addition,because New Orleans has a large population in vulnerable locations,emergency management officials must begin evacuations well before a storm strikes.But evacuation costs money:Businesses close,tourists leave,and citizens take precautionary measures.The mayor of New Orleans estimated that his city’s preparations for Georges cost more than 50 million.After the full fury of Georges missed New Orleans,some residents questioned the value of the hurricane forecasts in the face of such high costs.
The differing views on the early warnings for Hurricane Georges illustrate some of the complexities involved in predicting disasters.Disaster prediction is more than just forecasting the future with advanced technology—it is also a process of providing scientific information to the government officials and other decision makers who must respond to those predictions.
In general,the process has three phases.First,there is the challenge of forecasting the event itself.In the case of Georges,scientists worked to predict the future direction and strength of the hurricane days in advance.
A second important challenge is communicating the forecast to decision－makers.Because forecasts are always uncertain,a central factor in disaster predictions is communicating this uncertainty.Uncertainty is usually described in terms of odds or probabilities,much like daily weather forecasts.The media plays an important role in communicating predictions and their uncertainty to the public.
The third part of the process is the use of predictive information by decision makers.Even the most accurate information is of little value if the decision maker does not use it appropriately,for example in deciding whether to order an evacuation.If there is a breakdown in any of these three phases of prediction,the result is increased danger and a higher risk of loss of life.
小題1:The underlined word“calamity”refers to ______.
A．natureB．thunderstormsC．disasterD．dangers
小題2:According the passage,the purpose of disaster prediction is to______.
A．demonstrate the power of advanced technology
B．bring out the truth between life and death
C．prevent such natural disasters from happening
D．reduce human casualties and loss of property
小題3:Which of the following areas suffered the most severe damage?
A．Biloxi,Mississippi.B．Gulf Coast of U. S.
C．Galveston,Texas.D．New Orleans.

Comera is the only place in the world which has a whistle language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley can not easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.
4. 小題1:If a person on Comera island is ill,      .
A．others will phone the doctor in town
B．whistle language will pass the news to the doctor
C．his family will take him to the doctor
D．people will take him to the hospital
5. 小題2:From the passage we know radio and TV       at that time.
A．killed the special way of speaking
B．whistled all the news and opinions
C．helped Comera people to communicate
D．did not appear on Comera island yet
6. 小題3:Comera island is special in that      .
A．it attracts visitors every year
B．no visitors have ever been there
C．people there have special ears to hear whistles
D．people there use the whistle language to communicate with each other
7. 小題4:Which of the following is not true according to the passage?
A．It is not easy for a person to live on Comera island if he cannot whistle.
B．The whistle language can only be found in Comera.
C．The whistle language has been used for hundreds of years on the island, but will not be used any longer.
D．The record shows that one best whistler can be heard by others seven miles away.

Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries. For these countries, economic growth is a very important aim. They want to introduce industries, and so they put few controls on the industries which cause pollution.
Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants(污染物). The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places.
It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines(罰款) than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility(責任) does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely(嚴厲地) punished or even put out of business.
小題1:Why don’t developing countries have strict pollution controls?
A．The new industries they want to introduce do not cause much pollution.
B．Pollution is not a serious problem for developing countries.
C．They don’t realize the balance of nature will be destroyed by some pollutants.
D．If they put stricter controls on industry, fewer companies would build new plants in developing countries.
小題2:What is the author’s purpose in taking Cubatao as an example?
A．To show that industry can develop very fast in developing countries.
B．To show that the pollution problem in Brazil is extremely serious.
C．To show that industrial growth can cause pollution problems for developing countries.
D．To show that pollution is killing many people and destroying the whole economy of Brazil.
小題3: How is the health of the population of Cubatao?
A．There are more heart diseases among people who live near chemical factories.
B．More people suffer from lung diseases because of poisonous matter.
C．Their health is affected by pollutants the same way as that of other Brazilians.
D．Babies there are found not as bright as those who live in other places.
小題4:Why do some foreign companies like to set up their plants in Brazil?
A．The investment(投資) environment in Brazil is suitable for them.
B．They will not be severely punished if they cause pollution in Brazil.
C．They can make much money because they do not have to pay Brazilian workers much.
D．They can act in an irresponsible(不負責任的) way in Brazil because there are no pollution laws there.

Directions: Read the following passage. Fill in the numbered blanks by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.
A Low-Carbon Economy (LCE) refers to an economy which has a minimal emission of greenhouse gas (GHG), namely, carbon dioxide into the biosphere(生物圈). Recently, most of the scientists and the public hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere due to human activities. The over-concentration of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future. LCE, therefore, is proposed as a means to avoid catastrophic climate change.
All nations which are considered carbon intensive societies and societies which are heavily populated should become zero-carbon societies and economies. Several of these countries have promised to become 'low carbon' but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions rather than ceasing all emissions.
Nuclear power and the strategies of carbon capture and storage (CCS) have been proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources. Scientists are afraid, however, whether the spent-nuclear-fuel can be stored, and whether it is secure. Also they are not certain about the costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak into the biosphere or not. Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times. Furthermore, it has been proposed that to make the transition to an LCE economically attractive we would have to attach a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax.
A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to power-generation around technologies that produce energy and materials with little GHG emission and thus around populations, buildings, machines and devices which use those energies and materials efficiently and dispose of or recycle its wastes so as to have a minimal output of GHGs.
Title:        71       
I.          72       : an economy with a minimal output of GHG
II.         73        of the present economy:
● global warming
● long-term climate change
●            74           on humanity    
III.           75           :
● to produce energy and materials with little GHG emission
● to use those energies and materials efficiently
● to have          76            of GHGs
IV.            77            to achieve a LCE:
●nuclear power  
●the strategies of carbon capture and storage
● renewable energy    
●              78              
● a carbon tax
V.           79         :
● spent-nuclear-fuel storage / storage of spent-nuclear-fuel
●        80           
● uncertainty about the costs and time needed
