Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.

Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.

"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.

So hours of seemingly mindless eating grass may not be so mindless after all.

Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much ind

ividuality and are frightened of just about everything.

All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.

In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.

"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. "

From the first paragraph we can find that ______.

A. people used to think sheep are smarter than the other animals

B. people used to raise sheep in a wrong way

C. people don't consider sheep as clever animals

D. people have done a lot of research on sheep

From what Kendrick said in the interview we learn that ________.

A. scientists have learned a lot about sheep's intelligence

B. scientists have learned little about sheep's intelligence

C. scientists can't do anything more about sheep's memory

D. scientists don't have to research animals' memory

As is shown in the passage _________.

A. sheep are among the weak animals

B. it is not right for people to raise sheep in groups

C. when sheep eat grass in the fields their minds may be active

D. if people feel frightened, they may become more brave

When scientists found that sheep show similar abilities in many ways to humans they may think it _____.

If you’re training for a marathon , a proper plan for water intake (摄入) is important. Of course, there’s the risk of dehydration (脱水). But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium (钠) in the blood . The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.

Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.

One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.

Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water .

56. The author of this passage is primarily concerned with .

A. the signs and treatment for dehydration

B. the long distance runners who need help

C. how to manage water intake during a marathon

D. a 28-year-old woman who died after a Boston Marathon

57. Why do runners have to weigh themselves before and after a run ?

A. They can improve their performance in a run.

B. They can learn how much salt there is in the blood.

C. They can know the quantity of water they’ve lost during a run.

D. They can decide what kind of water they should take during a run.

58. What conclusion can we draw from the passage ?

A. Taking much salt during a run can avoid selling in the body.

B. Either too much or too little of water intake is harmful.

C. A rich meal is helpful to our performance in a run.

D. We should take enough salt during a run.

59．According the passage, which of the following statements is correct ?

A. Too much water intake→blood sodium levels ↓→dehydration.

B. Too much water intake→blood salt levels ↓→hyponatremia .

C. No water intake→blood sodium levels↑→hyponatremia .

D. No water intake →blood salt levels ↓→hyponatrenmia .

Home can be a great place for children to study. It’s important to provide a workspace of their own where they can read books or just write a letter to their friends.

● Location （位置）

72Kitchen and dining room are not so well suited for regular study, since books and pens get in the way of the day-to-day uses of those areas. Set up a place where a child can settle in and leave papers and pens at band without having to clear everything away each night. For a child that likes being alone, set aside a corner of his bedroom, but keep it separate from things like games, music and other hobbies not related to studying.
