Watching more than three hours of television a day doubles memory loss in older people, a new study of more than 3,000 adults suggests. The research team say they believe the "alert-but-passive" nature of television watching may be creating stress on the mind which contributes to memory decline. Older people who watch more television are also less likely to undertake activities known to preserve mental functioning such as reading, or interactive screen-based pursuits such as using the Internet or playing video games.Q: What contributed to memory decline in the participants?听音频并回答音频中的问题A、Watching television for hours.B、Playing video games.C、Reading books and magazines.D、Surfing the Internet.

We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways. It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns. Fear is another emotion that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like "he went pale and begin to tremble" suggests that the man is either very afraid or he has just got a very big shock. However, "he opened his eyes wide" is used to suggest anger in Chinese whereas in English it means surprise. In Chinese "surprise" can be described in a phrase like 'they stretched out their tongues!' Sticking out your tongue in English is an insulting gesture or expresses strong dislike. Even in the same culture, people differ in ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people's faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do. 【小题】(1) According to the passage, __________.A.we can hardly understand what people's gestures meanB.we can not often be sure what people mean when they describe their feelings in words or gesturesC.words can be better understood by older peopleD.gestures can be understood by most of the people while words can not【小题】(2) People's facial expressions may be misunderstood because __________.A.people of different ages may have different understandingB.people of different countries speak different languagesC.people of different sex may understand a gesture in a different wayD.people have different cultures【小题】(3) In the same culture, __________.A.people have different ability to understand and express feelingsB.people have the same understanding of somethingC.people never fail to understand each otherD.people are equally intelligent【小题】(4) From this passage, we can conclude __________.A.words are used as frequently as gesturesB.words are often found difficult to understandC.words and gestures are both used in expressing feelingsD.gestures are more efficiently used than words【小题】(5) The best title for this passage may be __________.A.Words and FeelingsB.Words, Gestures and FeelingsC.Gestures and FeelingsD.Culture and Understanding

That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the First-night, effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect. Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did. Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found. (1) What do we learn about Dr. Yuka Sasaki doing her research? A. She found birds and dolphins remain alert while asleep. B.

Directions: Read the following passage and choose the correct answer to each statement. When the early settlers, especially the English, arrived in the New World, the hardships, and dangers awaiting them were totally unexpected. Had it not been for some friendly Indians, the colonists never would have survived the terrible winters. They knew nothing about planting crops, hunting animals, building solid house or making clothing from animal skins. Life in England had been much simpler, and this new life was not what the Spanish explorers had reported. The settlers did introduce iron tools, muskets(步枪)for hunting , domesticated animals, and political way to the Indians. In exchange, the settlers learned to build canoes(独木舟)for water transportation and snowshoes for winter traveling. The Indians also taught them to penetrate through the forest, to hunt large animals and trap smaller ones, and to catch fish in the lakes and streams. The natives also introduced to the settlers typical local food. Everything possible was done in order to make their new settlement resemble the homes they had left behind. ( )The Indians were very cold to the settlers at the beginning. A A. True BB. False CC. Not Mentioned
