If you have ever experienced jet lag(飛行時差反應(yīng)),you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you’re likely to have problems.
Edward Norton’s character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That’s not something you should have to fight on a business trip and it certainly won’t make your vacation very enjoyable, either.
Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don’t worry. You can do something to prevent it.
Modify(改變)Your Body Clock
To prevent the effects on your body’s timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you’ll have a five-hour time difference to deal with. Plan for it.
Avoid Heavy Food and Alcohol(酒精)
Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn’t good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts(調(diào)整) before you decide to have heavy food or drink alcohol.

We have known for a long time that flowers of different plants open and close at different times of day. This is so    1   that there seems to be no need to ask the reason for it.

閱讀下面的短文,并根據(jù)短文后的要求答題(請注意問題后的字?jǐn)?shù)要求)。
[1] I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day. But I became invisible, absent from the conversation.
[2] The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver told us to be quiet because he could not hear the person on the other end of his cell phone. There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.
[3]Why is it that the more connected we get, ________________________ ? Every advance in communications technology is a hurt to the closeness of human interaction (互動). With e-mail and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone.
[4] More and more, l find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up because I didn’t really have time to talk. The industry devoted to helping me keep in touch is making me lonelier.

Scientists have created a “ human-like robot” that can dance and do the housework.
“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.
In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.
The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.
“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”
Through an advanced motion capture (捕獲) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.
State-funded KIST showed the robot during a presentation at its head office in Seoul.
People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.
The research team added that they had designed another “ Mahru”, this time with sensors(傳感器) allowing it to distinguish(分辨) between faces and objects.
The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅膠) skin that feels almost human to the touch.”
小題1: “Mahru” made by KIST can do the following things EXCEPT____________
A.dance with other human –like robotsB.move its body freely
C.stop automatically when walkingD.express certain feelings through smells
小題2: According to what You Bum- Jae said in Paragraph 5, his research team wants to ________.
A.help robots with doing houseworkB.show its scientific power
C.make Mahru offer more funD.explore Mahru’s commercial use

Unless we spend money to spot and prevent asteroids now,one might crash into Earth and destroy life as we know it,say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one,the scientists say,we'll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall,it would be the end of the world. “If we don't take care of these big asteroids,they'll take care of us,” says one scientist. “It's that simple.”
The cure,though,might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毀滅性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.
小題1:What does the passage say about asteroids and meteoroids?
A.They are heavenly bodies different in composition.
B.They are heavenly bodies similar in nature.
C.There are more asteroids than meteoroids.
D.Asteroids are more mysterious than meteoroids.
小題2: What do scientists say about the collision of an asteroid with Earth?
A.It is very unlikely but the danger exists.
B.Such a collision might occur once every 25 years.
C.Collisions of smaller asteroids with Earth occur more often than expected.
D.It's still too early to say whether such a collision might occur.
小題3: What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
A.It sounds practical but it may not solve the problem.
B.It may create more problems than it might solve.
C.It is a waste of money because a collision of asteroids with Earth is very unlikely.
D.Further research should be done before it is proved applicable.
小題4:We can conclude from the passage that ________ .
A.while pushing asteroids off course nuclear weapons would destroy the world
B.a(chǎn)steroids racing across the night sky are likely to hit Earth in the near future
C.the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime
D.workable solutions still have to be found to prevent a collision of asteroids with Earth.
小題5:Which of the following best describes the author's tone in this passage?
A.Optimistic.B.Critical.C.Objective.D.Subjective.

Do you blank out, freeze up or feel so nervous in exams that you have trouble writing answers to questions that you knew just last night? If so, you likely have a case of test anxiety.
But, don’t panic. By recognizing the problem, you are taking the first step towards overcoming it.
Believe it or not, a touch of nervousness can sharpen your mind, allowing you to perform more quickly. This is because under stress, the body releases the hormone adrenaline (腎上腺素), which prepares it for something important that will happen. However, too much anxiety can result in sleeplessness, loss of appetite(食欲) before tests, and poor performances. Some people might feel shaky, hot, or even sick.
If you worry a lot or are a perfectionist, you are more likely to have trouble with test anxiety. Those who have prepared poorly for a test or have had negative experiences taking tests may also experience test anxiety.
When you feel a storm of anxiety coming on, stop what you are doing and make your mind a blank. If possible, actually tell yourself to “STOP”. This will get your mind off the stress.
Then think of being at a place of comfort and let your body relax. As you continue the test, find questions you know the answers to and answer them first. This will help restore your confidence.
Talk to yourself using positive language. Make it a habit to replace each negative thought with a logical reason. For example:“ I’ve studied hard and I know the material, so I’m ready to do the best I can.”
Another thing you can do is to learn to accept mistakes. In fact, they can be valuable learning opportunities.
Last but not least, start test preparation early---three to five days ahead of the quiz or test. After all, good study habits and skills ---for example, time management and note-taking – will give you the feeling that your are in control.
小題1:The first step to overcome nervousness is___ .
A.stopping what you are doing, and make your mind a blank.
B.getting aware of your problem that you are always nervous
C.releasing a kind of body liquid.D.making full preparations
小題2:___ are more likely to feel very nervous in tests.
A.People who feel a touch of nervousness in tests.
B.People who haven’t prepared very well.
C.People who require that everything must be perfect.
D.People who have recognized their problems.
小題3: According to the passage, which statement is TRUE?
A.Those who have ever failed in tests must feel anxious.
B.A touch of nervousness is a good thing.
C.You should answer the questions on the paper one by one.
D.Full preparation is not as important as nervousness controlling.

In general, it seems reasonable to suppose that we should prefer peace and quiet to noise. And yet most of us have had the experience of having to adjust to sleeping in the mountains or the countryside because it was initially “too quiet”, an experience that suggests that humans are capable of adapting to a wide range of noise levels. Research supports this view. For example, Glass and Singer (1972) exposed people to short bursts of very loud noise and then measured their ability to work out problems and their physiological reactions to the noise. The noise was quite disruptive at first, but after about four minutes the subjects were doing just as well on their tasks as control subjects who were not exposed to noise. Their physiological reactions also declined quickly to the same levels as those of the control subjects.
But there are limits to adaptation and loud noise becomes more troublesome if the person is required to concentrate on more than one task. For example, high noise levels affect the performance of subjects who were required to monitor three dials at a time, a task not unlike that of a plane pilot or an air-traffic controller. Similarly, noise did not affect a subject’s ability to track a moving line with a steering wheel, but it did affect the subject’s ability to repeat numbers while tracking (Finkelm and Glass 1970).
Probably the most significant finding from the research on noise is that its predictability is more important than how loud it is. We are much more able to “tune out” long-lasing background noise, even if it is quite loud, than to work under circumstances with unexpected disturbance of noise. In Glass and Singer’s study, in which subjects were exposed to bursts of noise as they worked on a task, some subjects heard loud bursts and others heard soft bursts. For some subjects, the bursts were spaced exactly one minute apart (predictable noise); others heard the some amount of noise overall, but the bursts occurred at random intervals (unpredictable noise). Subjects reported finding the predictable and unpredictable noise equally annoying, and all subjects performed at about the same level during the noise portion of the experiment. But the different noise conditions had quite different after-effects when the subjects were required to proofread written material under conditions of no noise. The study shows that the unpredictable noise produced more errors in the later proofreading task than predictable noise; and soft unpredictable noise actually produced slightly more errors on this task than the loud predictable noise.
Apparently, unpredictable noise produces more fatigue than predictable noise, but it takes a while for this fatigue to take its toll on performance.
小題1:When talking about people’s difficulty in sleeping in the mountains, what can be inferred in the passage?
A.They usually do not prefer peace and quiet to noise.
B.They may be exposed to short bursts of very strange sounds.
C.They prefer to hear a certain amount of noise while they sleep.
D.They may not have adapted to a higher noise level in the city.
小題2:What did Glass and Singer find in their noise experiment?
A.Problem-solving is much easier under quiet conditions.
B.Physiological reactions prevent the ability to work.
C.Bursts of noise hardly disturb problem-solving in the long term.
D.The physiological reactions of the control subjects declined quickly.
小題3:Researchers discovered that high noise levels are not likely to affect the __________.
A.successful performance of a single task
B.tasks of pilots or air traffic controllers
C.a(chǎn)bility to repeat numbers while tracking moving lines
D.a(chǎn)bility to monitor three dials at once
小題4: What does “take its toll on performance” in the passage probably mean?
A.Destroy the performance completely.
B.Have a negative effect on the performance.
C.Improve the performance greatly.
D.Have a positive influence on the performance.
