When caught in pouring rain without an umbrella, most people pick up their pace. But an old tale says that a person who runs in the rain gets wetter than one who walks. It sounds reasonable that when someone runs up and down, the body is exposed to more drops of water.

But several studies have put this saying to the test and found it not to be true. One such test was carried out in 1987 and was published in European Journal of Physics magazine. The Italian physicist who did the experiment said that if the distance is short enough, running gets a person less wet than walking. But running only keeps you about 10 per cent drier. That is to say, running isn't worth the effort.

Another study, published in 1995 by a British researcher, found that it made no difference whether a person walked or ran.

Perhaps the final word came from two American scientists at the National Climatic Data Centre in North Carolina recently. They thought that earlier studies overestimated the average walking pace. So, they did a much more careful experiment than any of the previous ones.

They noticed that the direction of the wind really matters to the results of the experiment. They also found that runners like to lean forward, hiding the front of their bodies from rain, but exposing the back.

The researchers used themselves as guinea pigs(豚鼠) in the test. Over a distance of 100 metres, they found that running in heavy rain kept them drier by as much as 40 per cent.

The bottom line is running in the rain probably keeps you drier than walking. But do remember to take an umbrella with you! For long distances, without an umbrella, the results are the same, no matter you run or walk.

1.Which of the following statements in TURE according to the passage?

       A.All the studies show that running can’t help to keep you drier in the rain.

       B.It is the old tale that sounds believable.

       C.People should walk rather than run in the rain by the traditional standard.

       D.Running in the rain is not worth the effort.

2.The author may consider the research or advice by        more reasonable.

       A.the Americans                                     B.the British researcher

       C.the Italian physicist                              D.the old tale

3.It is          that plays an important role in deciding how much you will get wet.

      A.the walking pace                                  B.the wind             

       C.the distance                                         D.the way you lean

4.Which of the following do you think is the best title?

       A.Be Prepared for a Storm                       B.Walk Faster in the Rain to Get Dry

       C.The Importance of an Umbrella             D.Running or Walking

Dr. Sylvia Earle wants you to stop eating fish. It's not because fish are endangered, though wild fish stocks in many oceans are very low. It's not because they're bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they're smart.
"Fish are sensitive, they have personalities," says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. "I would never eat anyone I know personally."
There's a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether.
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. "While it may seem conspicuous that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables," says Dr. Lynne Sneddon. "Really, it's kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?"
Fishermen and (fried) fish lovers are skeptical. "I've never seen a smart fish," says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. "If they were very smart, they wouldn't get caught."
"For years, everyone's been telling us to eat fish because it's so good for us," says another diner. "Now I've got to feel guilty while I'm eating my fish? What are they going to think of next? Don't eat salad because cucumbers have feelings?"
【小题1】According to Dr. Sylvia Earle, he would stop eating fish as a result of the following reasons EXCEPT ___________ .

A.Fish are sensitive and have personalities
B.He knows fish very well
C.Fish are dangerous to eat because the water is polluted
D.Fish are clever
【小题2】Dr. Lynne Sneddon describes the behavior of eating fish in a(n) _______ tone.
A.opposedB.optimisticC.indifferentD.supportive
【小题3】Which word below can take the place of the underlined word “conspicuous” in Paragraph 4?
A.obviousB.easyC.impossibleD.necessary
【小题4】It can be inferred from the last paragraph that _____________ .
A.Human beings should stop eating fish
B.We would feel guilty if we continued eating fish
C.People eat fish because fish are delicious
D.Cucumber is a kind of vegetable or fruit
【小题5】What was the author’s purpose when writing this passage?
A.To advise people to stop eating fish.
B.To introduce a topic of whether people should eat fish.
C.To advise people not to stop eating fish.
D.To tell us that fish will feel pain when caught and transported.

Today, as with so many days, I found myself stuck in a traffic jam, and I thought I’d share my little trick for keeping calm when it seems like you are creeping along(缓慢行进).

   The key to understand is that traffic jams don’t take as long as they seem to. It’s just that when we are in a hurry, and think we should be moving, but time appears to pass more than it does. To really show this, the next time you are stopped at a light that always seems to take forever to change, try to do something with your phone, your laptop, whatever you have available, and watch how much briefer the light seems.

   When you enter a jam on the highway, reset your trip plan and care the time. Then, when you clear the jam, and are normally on your way again, care the distance of the jam, and the time it took to get through it. For my experience today, it took me 6 minutes to go 2 miles. Now, it happens to be mathematically convenient that your average speed on the highway is about 60 mph, or a mile per minute. So to estimate what time the jam actually cost you, just take your traffic jam passing time, and subtract(减去) the distance covered, which we know is a good estimate of the time it would have taken with no traffic jam. In my case, all that added up to 6-2=4 minutes.

   Do this for every jam you are subjected to every time and watch how much less stressful they become once you understand how little time you are really losing.

1.We can infer from Paragraph 1 and 2 that ________.

   A. there was no traffic jam in the past

   B. modern people are under great pressure

     time passes much faster during traffic jams

   D. people in traffic jams are usually impatient

2.What does the writer suggest when caught in traffic jams?

   A. Playing a trick on other drivers.

   B. Figuring out how much time the jam actually cost you.

     Doing some math problems.

   D. Informing the boss about the delay.

3.The underlined phrase “subjected to” in the last paragraph probably means ________.

   A. experience          B. avoid                 admit                     D. control

4. What’s the main idea of the passage?

   A. Math is closely connected with life.

   B. Stress is always a bad thing.

     Traffic jam is not as bad as you think.

   D. There is no use complaining about traffic jams.
