If you are having trouble falling asleep, you are in good company. About 65% of Americans said they have sleeping problems a few nights each week, according to a recent study by the National Sleep Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed(沮喪的). But before you go to a doctor for advice, it is worth examining your sleeping habits one more time. Some of your favorite evening habits may have something to do with the sleeping problems.
Setting a Bright Alarm Clock
The light of your bright alarm clock can prevent you from falling asleep. You can make your room as dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your cellphone alarm may also do the trick.
Counting Sheep
When you just can’t fall asleep, it’s useless to stay in bed to count sheep. If you’ve been trying to fall asleep for more than 30 minutes, the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it, you’ll be going back to bed really tired.
3. Exercising Late at Night?
Daytime workouts(鍛煉) will keep you full of energy for hours. That’s why you don’t want to exercise within three hours of hitting the sack. Fierce(劇烈的)  physical activity raise your body temperature and pumps your energy level—both are bad for a good night’s sleep.
小題1:What can we learn from the first sentence of the passage?
A．It’s not good to fail to fall asleep at night.
B．People in a good company often have sleeping problems.
C．There are many people who have sleeping problems.

A．The bad results of getting too little sleep.
B．Why the bright alarm clock keeps you awake.
C．What to do if you can’t fall asleep after 30 minutes.

小題4:By writing the passage, the writer mainly wants to tell us _______.
A．why so many people can’t sleep well at night

D．that people may solve their sleeping problems by some habits

Local fishermen said they caught the 3-meter-long, l-ton shark by chance When they were fishing in sea water 1,000 metres deep near the beach.

Fishermen later killed and sold the shark after oceanographers confirmed that it was a whale shark and therefore not under State protection.
The shark was believed to have drifted into the area from the deep sea due to strong waves caused last week by Typhoon Imbudo. It had no open injuries but experts said they believed it suffered from internal（內(nèi)部的）bleeding.
Local police officer Fu Chenggeng said beachgoers should not feel threatened by sharks because the fish never attack human beings on their own initiative. Fu said he had never heard of any shark attacks at the Sanya beach since he first started work there eight years ago.
However, police said they will improve the security system to safeguard tourists’ safety on the beach.

Millions of youngsters across Europe could suffer permanent hearing loss after five years if they listen to MP3 players at too high a volume for more than five hours a week, EU scientists warned.
The scientists’ study, requested by the European Commission, attacked the concept of “l(fā)eisure noise,” saying children and teenagers should be protected from increasingly high sound levels---with loud mobile phones also coming in for criticism（批評(píng)）.
“There has been increasing concern about exposure from the new generation of personal music players which can reproduce sounds at very high volumes without loss of quality,” the Commission, the EU’s executive arm, said in a statement.
“Risk for hearing damage depends on sound level and exposure time,” it said. More and more young people were exposed to the great threat(威脅)that leisure noise posed to hearing, it said.
Commission experts said that between 50 and 100 million people listen to portable music players on a daily basis.
If they listened for only five hours a week at more than 89 decibels(分貝), they would already be beyond   EU limits for noise allowed in the workplace, they said. But if they listened for longer periods, they risked permanent hearing loss after five years.
The scientists calculated the number of people in that risk category at between five and 10 percent of listeners, meaning up to 10 million people in the European Union.
Sales of personal music players have soared in EU countries in recent years, particularly of MP3 players.
"I am worried that so many young people ... who are frequent users of personal music players and mobile phones at high acoustic levels, may be unknowingly damaging their hearing ," she said in the statement.
小題1:Which of the following can be the best title of the article?
A．Youngsters across Europe: suffer permanent hearing loss.
B．MP3 players: sell best but do harm to youngsters
C．The scientists’ study: requested by the EU
D．EU warns youth: turn your MP3 players down!
小題2: This passage is most likely to be taken from a _________.
A．textbookB．medical report
C．teen magazineD．governmental newspaper
小題3:The underlined part in the forth paragraph most probably means________.
A．were uncoveredB．feltC．realizedD．were faced with
小題4:From the passage we know that________.
A．besides the high sound levels, scientists also criticized loud mobile phones.
B．if one listened for 5 hours more a week at 100 decibels, he would risk permanent hearing loss.
C．it is only the level of the sound that can do damage to hearing.
D．the scientists said there were 5-10 percent of MP3 listeners risking hearing loss around the world.

The conflict(爭(zhēng)執(zhí)) over what or how much homework should be comes partly from the fact that people can't seem to agree on the purpose of homework.
What teachers think?
Some teachers think that homework is necessary to reinforce(鞏固)what is learned in school. And so they ask their students to memorize what was discussed in class through homework..
Some teachers think the point of homework is to cover material that the class didn't have time to get to, so their homework is to let students learn additional things.
Other teachers like homework simply because they want students to form work habits and still others believe homework is necessary because it is the best way for parents to learn what their children do in school.
Parents' ideas.
But many parents seem to have different ideas.
Elissa Cohen,who has twins at Lafayette Elementary School, doesn't like the fact that third-grade students in DC elementary schools are asked to write about 25 book summaries a year. “They do the same thing over and over without really getting into alternate(交替) ways of thinking about books and thinking about reading and writing. ”
Experts' opinions.
Some education reformers (改革者), such as Howard Gardner, a Harvard University, professor well-known for his theory on multiple intelligence(智力), think that Cohen is on the right track. But it is often hard to persuade overworked teachers to give much thought to homework tasks.
60. How many opinions do the teachers have on "homework"?

New York Times---( DINITIA SMITH )Tomorrow is the 433d anniversary of Shakespeare’s birth. A recent survey shows that more people are watching him, reading him and studying him than ever before.
Consider the recent yearly conference of the Shakespeare Association of America in Washington, where more than 600 people who study or admire Shakespeare from 18 countries took in topics like ‘‘Whither Attribution Studies,’’ ‘‘Unpopular Shakespeare’’ and ‘‘Sex Me Here,’’ a talk on breast-feeding and Lady Macbeth.

Priced at $44.95, ‘‘The Norton Shakespeare: Based on the Oxford Edition’’ runs for 3,420 pages, offering introductions, illustrations and notes and three versions(版本) of ‘‘King Lear.’’
Today, movies and videos have made the plays even more accessible. Last year, ‘‘William Shakespeare’s Romeo and Juliet’’ was No. 1 at the box office when it opened, and it grossed nearly $50 million. In New York in January, crowds lined up in the freezing cold to see Kenneth Branagh’s four-hour ‘‘Hamlet.’’ The students select a scene and then have a violent discussion about it.’’ Influenced by films, professors are increasingly teaching students by having them perform the plays.

C
Perhaps you have never heard of Katherine Lawes．Katherine was the wife of Lewis Lawes, warden （監(jiān)獄長(zhǎng)） at Sing Sing Prison from 1920 to 1941．In these 21 years he made many reforms --- and an important part of his success was due to his wife Katherine．
Katherine took seriously the idea that the prisoners are human beings ,worthy of attention and respect ．She regularly visited inside the walls of Sing Sing．She encouraged the prisoners, took things to them and spent time listening to them．Most importantly, she cared about them．And as a result, they cared deeply about her．
Then one night in October of 1937, news was "telegraphed" between the prison cells that Katherine had been killed in an accident．The prisoners asked the warden to allow them to attend her funeral．He agreed to their strange request and a few days later the south gate of Sing Sing swung slowly open．Hundreds of men who had committed almost every crime imaginable marched slowly out of the prison, later gathered again at the gate and returned to their cells．There were so many that they proceeded unguarded．But no one tried to escape．If he had, the others might have killed him immediately．So devoted were they to Katherine Lawes, the woman who daily walked into Hell to show the men a piece of Heaven．
Katherine' s strength was to see the men less as prisoners and more as individuals．Thomas Moore once said, "We can only treat badly those things or people whose souls we show no respect for．"

Coal mine accidents are frequently headline makers in China, offering a plentiful supply of long lists of the dead．Before this, five major coal mine accidents since January have already claimed lives of 287 coal miners.
Once an accident happens, the safety measures are scrutinized, officials and owners responsible are punished or warned or fined．But the accidents keep happening time and again.
The background of this endless disaster is a country thirsty for energy to satisfy the appetite of its economic engine.
With the rich reserve（儲(chǔ)存）of coal and relatively limited petroleum（石油）reserve, the former makes up 67.12 percent of energy consumption．By contrast, petroleum and natural gas take about 60 percent of the energy consumption in other countries.
Such a situation is unlikely to change within a foreseeable future because the country still counts heavily on coal for more and more energy．If no measures with great effects are taken to improve the safety in the mines, the accidents will remain a long-term headache for China.
Digging coal underground is, by its nature, a dangerous job．No equipment can guarantee 100 percent safety for the miners working underground because numerous uncertainties exist.
Most of China’s coal mines are far from being mechanized．The average output of coal for each Chinese coal miner every day is 1 ton, while the number in the US coal mines, where the production is highly mechanized, is 40 tons.
Mechanized production in coal mines can cut down the number of miners who have to work on the dangerous coal face．It can also enhance the capability of the mines to detect potential danger．In this way mine accidents will be decreased.
Admittedly, the mechanized production demands financial support.
But what is the price of a life, or a dozen, a score – a hundred? Compare these awful figures with the misery they bring, heavy investment is worthy.
53．The writer’s attitude towards dealing with coal mine accidents is ________．         
A．critical    B．positive         C．unclear         D．doubtful
54．The underlined word “scrutinized” most probably means ________．               
A．made     B．examined       C．criticized        D．discussed
55．According to the writer, the best way to stop coal mine accidents is to ________.
A．perfect safety measures           B．use more natural gas
C．cut down the number of miners    D．improve mechanized production
56．The writer implies in the article that ________.
A．by improving mechanized production, we can stop coal mine accidents
B．it’s improper to depend too much on coal for energy consumption
C．officials and coal mine owners didn’t take safety measures seriously
D．losing lives costs much more than improving mechanized production
