    【题目】One day, Amy is digging in the ground for a potato when along comes Tom. Seeing that there is no one in sight, Tom starts to scream. Tom’s angry mother rushes over and drives Amy away. Once his mum has gone, Tom helps himself to Amy’s potato.

    We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Amy and Tom are not humans. They’re African baboons(狒狒).【1】

    Tom’s scream and his mother’s attack on Amy could have been a matter of chance, but Tom was later seen playing the same tricks on others.【2】

    Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated.【3】An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”

    Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe.【4】But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.

    It seems that trickery does play an important part in ape societies.【5】Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.

    A．An amusing example of this comes from a psychologist working in Tanzania.

    B．And playing tricks is as much a part of monkey behavior as it is of human behavior.

    C．So the psychologists asked his colleagues if they had noticed this kind of trickery.

    D．Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

    E. This use of a third individual to achieve a goal is only one of the many tricks commonly

    used by baboons.

    F. The ability of animals to cheat may be a better measure of their intelligence than their use

    of tools.

    G. In most cases the animal probably doesn’t know it is cheating.

    【题目】（London）—If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.

    Some doctors now think that the internal( 内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.

    “Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI（核磁共振） machines to create “fat maps” showing where people store fat.

    According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits （沉积）of internal fat, even if they are slim.

    Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body’s communication systems.

    The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.

    【1】What is this piece of news mainly about?

    A. Thin people may be fat inside.

    B. Internal fat is of no importance.

    C. Internal fat leads to many diseases.

    D. Thin people also have troubles.

    【2】Doctors have found _____.

    A. the exact dangers of internal fat

    B. internal fat is the cause of heart disease and diabetes

    C. being slim is not dangerous at all

    D. being slim doesn’t mean you are not fat inside

    【3】According to the passage, which of the following is WRONG?

    A. Exercise can help to reduce the internal fat.

    B. People can get rid of internal fat by improving diet.

    C. Men are more likely to have too much internal fat.

    D. People with heart disease all have internal fat.

    【4】From the last paragraph, we can find that _____.

    A. whether internal fat can lead to disease has been proved

    B. exercise plays an important role in people’s life for keeping healthy

    C. thin people usually have internal fat even if they are slim

    D. it is easier to burn off internal fat than external fat

    【5】The underlined part in the last paragraph means _____.

    A. a long road B. an easy way

    C. a clear difference D. a short distance

    【题目】B

    Banquets are usually held in restaurants in private rooms that have been reserved for the purpose. You will be met at the door and led to the banquet room. Traditionally, the head of your delegation should enter the room first. Do not be surprised if your hosts greet you with a loud round of applause. The proper response is to applaud back.

    Seating arrangements are stricter than in the West. Guests should never assume that they may sit where they please and should wait for hosts to guide them to their places. Traditionally, the Chinese regard the right side as the superior and the left side as the inferior. Therefore on formal occasions, the host invariably arranges for the main guests to sit on his right side.

    It is the host's responsibility to serve the guests, and at very formal banquets people do not begin to eat until the host has served a portion to the principal guest. Or, the host may simply raise his chopsticks and announce that eating has begun. After this point, one may serve oneself any food in any amount. Remember to go slow on eating. Don't fill yourself up when five courses are left to go. To stop eating in the middle of a banquet is rude, and your host may incorrectly think that something has been done to offend you.

    Drinking takes an important place in Chinese banquets. It is likely that the host will stand and hold his glass out with both hands while saying a few words. When he says the words "gan bei", which means bottoms up, all present should drain their glasses. After this initial toast, drinking and toasting are open to all. No words are needed to make a toast, and it is not necessary to drain your glass, although to do so is more respectful. When filling another glass, it is polite to fill it as full as you can. This symbolizes full respect and friendship.

    When the last dish is finished, the banquet has officially ended. There is little ceremony involved with its conclusion. The host may ask if you have eaten your fill. Then the principal host will rise, signaling that the banquet has ended. Generally, the principal host will bid good evening to everyone at the door and stay behind to settle the bill with the restaurateur. Other hosts usually accompany guests to their vehicles and remain outside waving until the cars have left the premises.

    【1】To attend a formal banquet,you_______.

    A.may enter the banquet room directly when you arrive .

    B.may stop eating in the middle of the banquet.

    C.may help yourself to any food immediately the dishes are served.

    D.should applaud back when greeted with a loud round of applause .

    【2】What is the host ‘s responsibility in the author’s eyes?

    A.Announcing that eating ends.

    B.Driving guests to their home.

    C.Filling the guests’ glasses.

    D.Arranging for guests to go to their place..

    【3】We can conclude form the passage that____

    A.To stop eating halfway means that the dishes taste bad.

    B.Guests should drain their g1ass es the instant they are filled

    C.Important guests are arranged to sit on the host’s right side

    D.The more you drink , the more you respect the host.

    【4】The passage mainly tells us ____

    A.Chinese food is delicious.

    B.customs and traditions at banquets in China

    C.what food guests should eat at banquets

    D.different customs between China and western countries.

    SSA gave Karl six months to pay the debt in . Otherwise, the SSA letter said, the agency would seize his home. Karl wrote back, asking if it would be okay to $30 a month. That was all he could .

    “That’s insufficient,” said William Shatner, an SSA agent. “We know that he is a war veteran, but that doesn’t entitle him to . He knew that his wife was dead, yet he cashed her monthly . That is fraud, pure and simple.”
