There is an effect that not only have we all witnessed， but have26. Haven"t we all been on an elevator and noticed that just about everyone stops talking when they get on？ Why do we do that？ You can be having a 27 pleasant conversation with someone， and as soon as you get on an elevator， you just feel like you"d better shut up.

Then， as soon as the doors open， everyone28conversation. Primatologists， or people who study primate （灵长类动物） behavior， have a term for this. It"s called the "elevator effect，" though it doesn"t 29 only on elevators. It happens whenever a group of primates， like humans， is 30 a situation where escape is 31 impossible. It"s thought to be a kind of safety32: as long as nobody talks， nobody is going to risk getting in a fight when there"s no way to spread out. The elevator effect keeps a lid on potential problems before they start.

Even though they rarely if ever ride elevators， chimpanzees demonstrate the elevator effect as well. When chimps are temporarily crowded together into small areas， they will 33 their vocal communication， that is， nobody speaks， and avoid eye 34. The amount of scratching the chimps do， however， goes up. Since scratching is a sign of stress in chimps， we can imagine what they are feeling. It"s just like what we feel in a crowded elevator——everybody carefully35 the lighted numbers and no one saying a thing.

Did you ever wonder what occurs inside your body when something funny happens？ What is this thing we have in our brains that makes us say "ha-ha" when someone26abanana？

One way to find out is to watch the brain laugh. That"s what Dartmouth neuroscientist William Kelley did. He and his team had a number of volunteers watch an27of Seinfeld while being monitored by an MRI， a machine that allows researchers to see which parts of the brain are active at any 28 time. They then matched the MRI data with the laugh track to see how the brain changes when it"s 29 something funny. There"s no one "funny center" in the brain——but the findings were pretty.

When subjects were looking at something funny， the two regions in their left hemispheres lit up. From 31 studies these regions are known to be associated with resolving unclear meanings. Is there something in "getting it" that"s 32 the process by which we work with unclear information until we suddenly see the pattern in it？

A couple seconds later two other brain regions became 33， called the insula（岛叶） and the amygdala（扁桃腺）. The insula is associated with 34， so it seems likely that this is the brain feeling good when it gets the joke——the "ha-ha" response. The amygdala is associated with memory formation. As the researchers35，while you may not be able to remember every plot detail in an episode of a soap opera， you can probably remember the jokes. Humor stays with us， forming a lasting memory.

For many years， food vendors in American cities have offered selling food from trucks. Hungry people can find more than just hot dogs in these26. Now looking for new clothing is becoming as easy and satisfying as exploring the tasty 27 of food trucks. The new movement is called the fashion truck. Once a month， just after sunset， trucks fill an outdoor parking lot in Los Angeles， California. Some trucks sell all kinds of food products， from sweet ice cream to 28 seafood. Others have clothing or29for sale. These vehicles are known as fashion trucks.

Many people have never seen a fashion truck before. Janelle Shepard is exploring everything inside the J. D. Luxe fashion truck. The back of the truck is a30. Clothing hangs on one side. Jewelry and purses are on the other side. The store is31 and looks well organized. There is also a very small room for 32 clothes. Another reason to use a truck is that you can take your business to the customers. But she also admits there are difficulties. The biggest challenge is 33 the weather while another issue is keeping the truck in good condition. When a vehicle 34.， the repairs can take days.

听音频，回答题

Elephants have a complex social structure and they live in26societies. The basic family unit is formed of small groups of adult females， who are 27 each other， and their young of both sexes. Now the females remain in their families for life， they"re highly social， but male elephants leave their families at about fourteen years of age. They travel alone or stay together in small，28 groups with other males，29 joining a family on a temporary basis. When males are ready to mate they wander widely， searching for 30 females. The family unit， on the other hand， often contains three generations， and it can remain stable for decades， or even centuries. Then each family 31 between one and five other families， probably consisting of their more distant relatives. Scientists call these groups of families "bond groups"， and bond groups belong，32， to even larger groups， called clans. And like other social animals they have to be able to communicate. But what baffled early33was their ability to communicate over long distances. So they set about researching this question. After years of observation and study， our understanding of elephant communication has increased considerably in recent years. However， even with the use of radio tracking collars， it"s technically difficult to 34 the functions of long-range communication. So although scientists are aware that elephants may know the whereabouts， and possibly the activities of other elephants that are several miles away，there may be a lot of subtle， long-range35which are still not evident.

请根据短文的内容，回答题。

Some Unusual Celebrations

Some holidays are well-known all around the world. Among them are New Year&39;s Eve celebrations.＜br＞

Also common are days in honor of love and friendship, like Valentine&39;s Day. Each country has its own special holidays, too, often to mark important events in its history. Schools, banks, and government offices all close on days like these. __________ (46) A few of them are really very strange.＜br＞

Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool&39;s Day, for example. No one knows when or why it began. Today it is celebrated in many countries- France, England, and Australia, among others. On this day, people play practical jokes. __________ (47) The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you？＜br＞

Day in Poland seems strange, too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part: They do it to girls they like. Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. __________ (48)＜br＞

For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.＜br＞

August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. __________ (49)＜br＞

There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day？ That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 9. __________ (50)＜br＞

Do you like the idea of inventing a new holiday？ If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.

根据下面材料，回答题。 What Should We Do before We Have a TestBefore a big exam, a sound

根据下面材料，回答题。

What Should We Do before We Have a Test

Before a big exam, a sound night&39;s sleep will do you more good than poring over textbooks.

That, at least, is the folk wisdom. And science, in the form. of behavioral psychology, supports that wisdom. But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. One says that sleep is when permanent memories form. The other says that they are actually formed during the day, but then "edited" at night, to flush away what is superfluous.

To tell the difference, it is necessary to look into the brain of a sleeping person, and that is hard. But after a decade of painstaking work, a team led by Pierre Maquet at Liege University in Belgium has managed to do it. The particular stage of sleep in which the Belgian group is interested in is rapid eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as if watching a movie,and brainwave traces resemble those of wakefulness. It is during this period of sleep that people are

most likely to relive events of the previous day in dreams.

Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task during the day, and as they slept during the following night. The task required them to press a button as fast as possible, in response to a light coming on in one of six positions. As they learnt how to do this, their response times got faster. What they did not know was that the appearance of the lights sometimes followed a pattern--what is referred to as "artificial grammar". Yet the reductions in response time showed that they learnt faster when the pattern was present than when there was not.

What is more, those with more to learn (ie., the "grammar", as well as the mechanical task of pushing the button) have more active brains. The "editing" theory would not predict that, since the number of irrelevant stimuli would be the same in each case. And to eliminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they went to sleep.

The team, therefore, concluded that the nerve connections involved in memory are reinforced through reactivation during REM sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soundly in the knowledge that what they will remember the next day are the basic rules of algebra and not the incoherent talk from the radio next door.

Researchers in behavioral psychology are divided with regard to__________. 查看材料

A.how dreams are modified in their courses

B.the difference between sleep and wakefulness

C.why sleep is of great benefit to memory

D.the functions of a good nights sleep
