第2题：
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). Several formulas are used for this purpose.
A.physical
B.network
C.transport
D.application@@@SXB@@@A.path
B.window
C.response
D.process@@@SXB@@@A.process
B.segment
C.program
D.user@@@SXB@@@A.connections
B.requests
C.acknowledgments
D.datagrams@@@SXB@@@A.long
B.short
C.fixed
D.dynamic

We consider it important that every citizen ____________ good manners.A.has
B.should be
C.have
D.is答案：C解析：考查虚拟语气。it为形式宾语，真正的宾语为后面的that从句。该结构为：主语 think／consider／make／find… it 形容词 that从旬。当形容词为surprising，strange，natural，necessary，important等时，that从句中谓语常用虚拟语气，should 动词原形，should可省略。句意为“我们认为每个市民有礼貌是重要的”。“have good manners”表示“有礼貌”，故选C。 -

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______.Ashops have closed down
Bpeople buy as much as they can
Cfarmers can produce no more
Dpeople eat more vegetables

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.答案：D解析：save的含义有“挽救，储存，保留，解放”。根据文章第一段的上下文我们知道作者是说我们往往把情感中最后的部分保留给和他人相关的最重要的两种感情，因此选择选项A。 keep up是指“保持”，不符合上下文。
文章提到爱是positive feeling，而恨是negative feeling，因此两者是完全对立的情感。并且第一段第一句就讲到了爱的反面是恨，因此选项D是正确的。
文章第三段最后一句总结道无论哪种类型的爱，它们共同的特点是“a strong positive feeling toward another"，即讨另一个对象强烈的积极的感情。因此只有选项B是正确的。
文章最后一段第一句讲到恨是由于“anger, jealousy, or some other factor”造成的，因此选项A是正确的。选项C列举的是构成爱的因素，选项D不应该说恨是积极的情感。
文章第四段解释人类的感情是复杂的，不是单一的，我们可以对他人同时怀有不同种类的感情。因此选项D是正确的。选项A, “too simple an emotion”错误，第一段说对爱的研究较少有两个原因：首先是，爱是非常复杂的感情，很难描述和衡量。其次，强热的爱并不是个问题。选项B不正确，“强烈的爱很难描述和衡量”和“很少的药物治疗”之间并无因果关系。很少药物治疗的原因应该是强烈的爱并不是个问题。选项C的描述也不正确，作者认为恨有时也是好的。 -

第21题：
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.
