Most animals have little connection with animals of different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership ( 伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals ( 珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.1、Some birds like to sit on a sheep because ( ).A、they can eat its parasitesB、 they depend on the sheep for existenceC、 they enjoy traveling with the sheepD、 they find the position most comfortable2、The underlined word "they" in the last sentence of the first paragraph refers to ( ).A、birds and parasitesB、birds and sheepC、parasites and sheepD、sheep, birds and parasites3、What does the second paragraph mainly discuss? ( )A、Some animals and plants depend on each other for existence.B、 Some animals and plants develop their relationship easily.C、 Some plants depend on each other for fooD、 Some animals live better together.4、What does this article talk about? ( )A、Two kinds of animals for a partnership.B、Most animals only have connection with animals.C、The connection between the living things.D、Corals have some connection with plants.

The TCP protocolis a (71) layer protocol. Each connection connects two TCPs that may be just one physical network apart or located on opposite sides ofthe globe. In other words, each connection creates a (72) witha length that may be totally different from another path created by another connection. This means that TCP cannot use the same retransmission time for all connections. Selecting afixed retransnussion time for all connections can result in serious consequences. Ifthe retransmission time does not allow enough time for a (73) to reach the destination and an acknowledgment to reach the source, it can result in retransmission of segments that are still on the way. Conversely, if the retransnussion time is longer than necessary for a short path, it may result in delay for the application programs.Even for one single connection, the retransmission time should not be fixed.A connection may be able to send segments and receive (74)faster during nontraffic period than during congested periods. TCP uses the dynamic retransmission time,a transmission time is different for each connection and which may be changed during the same connection. Retransmission time can be made(75) by basing it on the round-trip time (RTT).

第二篇Love or Hate?We have saved as a final set of emotions to two most important emotions connected with other people:love and its opposite,hate.Love can be seen everywhere.Yet surprisingly,love has been the subject of less scientific research than other emotions,such as anger and fear. The reason for this may be two fold.Firstly,love is a very complex emotion,difficult to describe and measure. Secondly,unlike many radical emotions,radical love is generally not a problem. Thus less medical attention has been paid to it.What is love?This is a complex question and requires a complex answer. Love is a strong,positive attraction and feeling for another person or thing. But it is more than this.It also involves feeling of caring,protection,excitement,and tenderness.When two people are in love,they feel drawn to one another;they greatly enjoy each other's company;and they may be sexually attracted to one another.Sometimes it is easier to think in terms of different kinds of love:romantic love,brotherly love, and so forth.Though they are different in some respects,they share one important characteristic: a strong positive feeling toward another.Our feelings toward other people are often complex.We may love someone and,at the same time,be angry with him.Or we may love someone,even though we are jealous of him.We mighi even love someone and,at the same time,hate for some precise reason.Hate is a strong negative emotion toward someone,and is due to anger,jealousy,or some other factor. Like love,hate can be a very strong emotion.It can also be very dangerous.The question is often asked,"Is it bad to hate?"The best answer is probably" sometimes yes and sometimes no." Usually hate does not help us.It makes us feel unhappy and makes us do things that may hurt others.However,sometimes it may be necessary to hate and hurt someone in order to protect loved ones.Which of the following is true?A:Love has been the subject of less scientific research because it is too simple an emotion.B:Radical love is so difficult to describe and measure that less medical attention has been paid to it.C:To hate is always too bad.D:We can have at the same time two opposite feelings for another.

Body Language in the United States1.Most people shake hands and make eye contact when they meet people for the first time.Among very good friends,a woman may give another woman a little hug,and a man may kiss a woman quickly on the cheek.Males don't usually hug one another,however,this is changing.Men usually shake hands with the right hand.Sometimes they use the left hand to either cover the handshake or lightly hold the other person's arm.This shows greater warmth and friendship.Most people wave hello or good-bye by extending the arm,palm facing outward,and twisting the hand at the wrist.Another way is to raise the arm,palm outward,and move the whole arm and hand back and forth.This is important to know because in many other countries,the same movements mean"no".2.When people are waiting in a public place,such as the post office,they usually form lines.Some people get angry and complain if someone pushes their way into a line or jumps ahead of other people.Moreover,many women like men to open doors for them.They also like men to give up their seats on public transportation.However,some women do not like this type of behavior.They feel that men and women should be treated in the same way.3.In the United States,it's important to make direct eye contact in business and social situations.If you don't make eye contact,people will probably think that you are bored or not interested.If there is silence in these situations,people usually try to make conversation.Periods of silence make many people uncomfortable.People in the United States usually stand about one arm's length away from each other while talking or standing together.This space is called"the comfort zone".4.In the United States,mothers sometimes show that they are angry with children by shaking an index finger at them.People may show that they like children by patting them on the top of the head.Paragraph 1________A:Body Language With ChildrenB:Body Language for Greetings and Good-byesC:Body Language in Public PlacesD:Impolite Body LanguageE:Body Language in Business and Social LifeF:Use of Silence

问答题Cultural Attitudes towards Time According to anthropologist Irving Hallowell, there is no evidence that humans have an inborn sense of time. A person’s temporal concepts are probably determined largely by culture. One study showed that infants, after a few days of listening to speech around them, will move their heads and limbs in rhythm with the speech they hear. As children develop, they adapt more fully to their temporal culture. This temporal culture influences language, music, poetry and dance. It also affects relationships. We tend to get along well with people who share our sense of time. One particular cultural attitude towards time is found in polychronic cultures. Some Mediterranean and southwest Asian Cultures are usually placed in this category. Such cultures emphasise relationships among people, flexible timing of appointments, and the careful completion of processes rather than strict schedules. Polychronic people seldom feel that time is being wasted. They tend to consider each activity valuable on its own, not just as part of a larger process. Polychronic people tend to have many projects going on at the same time, and they may shift frequently from one task to another. They change plans often. For polychronic people, work time is not clearly separable from personal time, so business meetings are considered a form of socialising. Monochronic cultures, on the other hand, are oriented towards tasks and schedules. Cultures usually considered monochromic can be found in northern Europe, North America, and some parts of eastern Asia. Monochronic people feel that time is tangible and inflexible and that “time is money.” They do one thing at a time and concentrate on each thing. Time and job commitments are very important to them and they tend to follow plans rigidly. Also, monochromic people clearly separate their work and personal time, and they place a high value on privacy. As you might expect, people from polychronic and monochromic cultures often misunderstand each other because of their different senses of time. For example, because a monochromic culture is highly compartmentalized, monochromic people tend to sequence conversations as well as tasks. They would not, for instance, interrupt a phone call in order to greet another person who just came into the room In contrast, polychronic people are comfortable with having multiple conversations at the same time. They would consider it rude not to greet someone who entered during a phone conversation. Complete the summary below by choosing for each blank no more than three words from the passage. Cultures may have either a 1 or a monochromic conception of time. Cultures with a polychromic view of time follow a 2 timetable. People from polychronic cultures tend to work on severa 3 at the same time. On the other hand, people in 4 perceive events and tasks as being more compartmentalized. In this culture, jobs and even conversations should follow a certain 5 Everything in these cultures seems inflexible, and has its own place and time.

单选题Passage1 Questions 1 to 5 are based on the following passage. It's interesting that the arrival of snow has the effect on people in different countries.(76) For some countries it is an important happening to celebrate each year, while for others a catastrophe （灾害） or even a wonder. But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year.Britain is one of them, for which the arrival of snow quite simply creates problems.Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way.Normal communications are affected as well: telephone calls become difficult and the post immediately takes more time than usual.And almost within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops,but mainly because people are frightened and go out and store up with food and so on...just for fear that something bad should happen. But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don't have such problems.It is simply because there is not enough planning and preparation.We need money to buy equipment to deal with snow and ice.To keep the roads clear, for example,requires snow-ploughs (扫雪机) and machines to spread salt.(77) The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.3 After a few hours' snowing there are often some shortages of food because______.A
shops have closed downB
people buy as much as they canC
farmers can produce no moreD
