You probably think college students are experts at sleeping.But parties，preparations for tests，personal problems and general stress can wreck a student’s sleep habits，which can be bad for the body and the mind.Texas Tech University is even offering a class called“Improving Your Sleep Habits”.[1]People suffering from sleep loss are at an increased risk from obesity,psychological problems and car crashes.Students who don't get enough sleep have poorer attendance and lower grades.On top of all that，[2] a new study published in the Journal Learning&Memory finds you're probably better off sleeping than making last-minute preparations for a test.200 college kids were taught to play some unfamiliar video games.Subjects who learned the games in the morning lost some skills when they played again 12 hours later，but they did much better after getting a good night’s sleep.[1]So.if you really want to do your job well,don't forget to get some sleep.

Long queues，delayed flights and overcrowding at airports have become almost as much a topic for conversation in Britain as the traditional complaining about the weather.Meanwhile，there’re complaints：the poor service at London’s major airports is discouraging foreigners from doing business in Britain.Much of the criticism is directed at the British Airports Authority,which runs 7 major airports，including the 3 main ones serving London.[3] The Competition Commission is now to investigate whether the British Airports Authority needs to sell off some of its assets.The idea is that competition between rival operators would lead to better service at airports.[4]The British Airports Authority recently bought by a Spanish company,says the root cause of the problems is not the ownership structure,but a lack of runway and terminal capacity,which is addressing through a programme of heavy investments.

[5] Under the law in Massachusetts,tobacco companies have to measure the nicotine content of every type of cigarette and report the results.[6]The Department of Public Health in Boston gathers and carefully examines the figures，and then draws its conclusions：116 brands were looked at for the study.82 were found to have
higher nicotine yields than they did 6 years previously.[6]The biggest increase is tended to be in brands that were popular with young smokers，that worries the Department because of the addicted nature of nicotine.Stanton Glantz，a professor of medicine in San Francisco explains why.“The amount of nicotine was delivered in every type of cigarettes is 10 percent higher than it was 6 years ago，which means that it’s easier to get hooked and harder to quit.[7]The big tobacco companies have always insisted that they are flank with their customers about the dangers of smoking and provide them with enough detail to make an informed decision.However，[7]none of them were prepared to comment on this study or discuss the detailed nicotine content of their products.”

Conversation One听力原文：
M：And you know...one thing that l want to ask you.It’s greatly you have had this experience of teaching in Indonesia.And following up on what you just mentioned，what would you recommend for students who do not live in an English—speaking country?And，you know,they want to learn?I don’t know about perfecting， but they want at least to be able to communicate decently.How can they go about this?
W：Yeah.it’s really hard.That’s the real struggle because…[8]Right now I do live in Holland but I really don’t socialize much with Dutch people.[10]And my boyfriend's English is so good that we just basically speak English all the time.so I have to make a real effort to practice.There’s as much listening exposure as I want.All I have to do is turn on the TV
M：And reading also.right?
W：Yeah.reading.There’s plenty that I can get to read and listen to.But for speaking，there really is no substitute for trying to speak and use the language in a relaxed atmosphere.[9] So.I think that's really the challenge for people who live in a country where their target language isn't spoken. And for that…gosh，what would I do?If I didn’t have people here，probably，try to find a club… [11]In Sweden they have a really cool system called“study Circles”.where it’s not…it’s like a course.but really,you just have a course leader who’s mere sort of as a coach and guide.and to help out...And you don’t get grades.and you go just because you want to learn.
W：OK，Nathan.[12]So we’re talking about driving and are there any rules or regulations that You’d like to change?
M：I'm not sure I want to change rules.but I’d like to please to be strict on the roads，like，if people jam the traffic lights.I don’t know why there isn’t a camera at the traffic lights to stop people doing that.All like speeding，it’s very easy to put speed cameras in certain places.
W：[13]Maybe car manufacturers should have some responsibility in limiting their power of their engines.What’s the point in producing an engine that’s big and powerful enough to go like 200km/h when the speed limit is only 100?
M：Right.But do you know there’s no speed limits in Germany?
W：[14] People there do drive responsibly,though. Often，people break laws simply because the laws are there.If the law isn’t there，people will drive within their ability range.When you’ve got speed limits，this creates situations actually present dangers on the road.
M：Do you think Germans have better education about personal responsibility when driving?
W：Possibly,they also have very good cars.
M：Right.
W：If you’ve got a good car that can go at a high speed then it’s very nice to do that.
M：But still with care.
W：So.I think it’s the restriction that creates the dangers sometimes.
M：OK.
W：Obviously.when driving through a residential area，or where there’s a school，you’ve got to have speed policemen.
M：Speed bumps.
W：Yes.speed bumps-those speed-bumps that force you to slow down.I think they’re good idea.
M：So，[15]you don't think fining people is useful?
W：[15]Not really,because the police don’t have time to police every single driver.

Passage One听力原文：
Behind the cash register at a store in downtown San Francisco，[16]Sam Azar swiped his cred“card to pay for a pack of cigarettes.The store's card reader failed to scan the card's magnetic strip.Azar tried again and again.No luck!
As customers began to queue，Mr.Azar reached beneath the counter for a black plastic bag.[l7]He wrapped one layer of the plastic around the card and tried again.Success!The sale was completed.
“I don’t know how it works.It just does，”said Mr.Azar who 1eamed the trick from another clerk.Verifone，the company that makes the store’s card reader,would not confirm or deny that the plastic bag trick worked.But it’s one of many low—tech fixes for high—tech failures that people without engineering degrees have discovered，often out of desperation，and shared.
[18] Today's shaky,economy is likely to produce many more such tricks.“In postwar Japan，the economy wasn’t doing so great，so you couldn’t get everyday—use items like household cleaners，”says Lisa Katayama，author of Urawaza，a book named after the Japanese term for clever lifestyle tips and tricks.“So people look for ways to do with what they had.”
Today,Americans are finding their own tips and tricks for fixing malfunctioning devices with supplies as simple as paper and glue.Some，like Mr.Azar’s plastic bag，are open to argument as to how they work，or whether they really work at all.But many tech home remedies can be explained by a little science.
