TOKYO：Elderly people who drink several cups of green tea a day are less likely to suffer from depression（消沉，压抑），probably due to a “feel good” chemical found in this type of tea，Japanese researchers said．
Several studies have related drinking green tea to reducing psychological problems and Kaijun Niu，of Tohoku University Graduate School，and colleagues found people aged 70 and older who drank four or more cups of green tea daily were 44 percent less likely to experience depression．
Green tea is widely drunk in many Asian countries，including China and Japan．
Niu's team studied 1，058 healthy elderly men and women．About 34 percent of the men and 39 percent of the women had signs of depression，according to the study that was published in the American Journal of Clinical Nutrition．
A total of 488 participants（参与者）said they drank four or more cups of green tea a day，284 said they downed two to three cups daily and the rest reported having one or fewer cups daily．
According to the researchers，the apparent effect of drinking more green tea on alleviating depression did not become less after they considered other factors， such as social economic status，sex，diet，history of medical problems and use of antidepressants．
There was no link between drinking black or oolong tea，or coffee，and lower degree of depression．
The amino acid theanine，contained in green tea，which is thought to have a calming effect on the brain，may explain the beneficial effect shown in the current study，Niu noted，adding that more study is needed．
1．Which of the following do you think can best replace the underlined word “alleviating” in paragraph 6?
A．Lowering the degree of B．Raising the degree of
C．Making…more difficult to bear D．Causing more suffering from
2．Which of the following do you think can serve as the most suitable title?
A．Feeling depressed? Coffee can cure． B．Feeling sad? Black tea does work．
C．Feeling upset? Oolong tea will do． D．Feeling blue? Green tea may help．
3．What’s the writers attitude towards the result of the study?
A．He is interested in it and totally supportive of it．
B．He holds the opinion that it is of little value．
C．He only reports the fact without mentioning his own opinion．
D．He seriously criticizes the result of the study．

London—Sheep, like turkeys and ostriches, are not considered the most clever animals. British scientists said last Wednesday humans may have underestimated the woolly creature. They could be much smarter than we think.
Researchers at the Babraham Institute in Cambridge, southern England, have shown that the 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 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, they have to have reasonable intelligence; otherwise, what is the point of having a system for remembering faces and not 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 (unable to speak, unintelligent) animals because they live in large groups and do not appear to have much individuality 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 which look extremely similar.
“The most important finding (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 individuals for a very long time,” said Kendrick. “It is a very strange system. They are showing similar abilities in many ways to humans.”
1.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
2.From what Kendrick said in the interview we learn that_____. .
A．scientists have learned everything about sheep’s intelligence
B．scientists have learned a little about sheep’s intelligence
C．scientists can’t do anything more about sheep’s memory
D．scientists do not have to research animals’ memory
3.As is known in the passage,__________.
A．sheep are among the week animals
B．it is not right for people to raise sheep in groups
C．when sheep eat grass in the field their minds may be active
D．if people feel frightened, they may become braver

These young men were a different kind of prisoner from those we had seen before. They- were brave, hostile（怀敌意的）and＿1__ they would not take orders, and shouted "Amandla！”at every opportunity. Their instinct was to confront（对抗）rather than cooperate. The authorities② did not know how to handle them, and they turned the island upside down. During the Rivonia Trial, I remarked to a security policeman that if the government did not reform itself, the freedom fighters who would take our place③would some-day make the authorities miss us. That day had indeed come on Robben Island.
??? In these young men we saw the angry revolutionary spirit of the times. I had had some warning. On a visit with Winnie a few months before, she had managed to tell me through our coded conversation that there was a rising class of discontented youths④ who were violent and Africanist in beliefs. She said they were changing the nature of the struggle and that I should be aware of them.
??? The new prisoners were shocked by what they considered the inhuman conditions of the island, and said that they could not understand how we could live in such a way. We told them that they should have seen the island in 1964. But they were almost as sceptical of us as they were of the authorities. They chose to ignore our calls for discipline and thought our advice weak and unassertive（不果断）．
??? It was obvious that they regarded us, the Rivonia Trialists⑤，as moderates⑥（温和派）． After so many years of being branded a radical（激进的）revolutionary, to be seen as a moderate was a novel and not altogether pleasant feeling. I knew that I could react in one of two ways：I could scold them for their disrespect or I could listen to what they were saying. I chose the latter.
??? 'then some of these men, such as Strini Moodley of the South African Students' Organization and Saths Cooper of the Black People's Convention, came into our section, I __2____
??? Shortly after their arrival on the island, the commanding officer came and asked me as a favour to address the young men. He wanted me to tell them to behave themselves, to recognize the fact that they were in prison and to accept the discipline of prison life．I told him that I was not prepared to do that. Under the circumstances, they would have regarded me as a follower of the authorities.
