正确答案:【错误】

5.选择题:对于一个结点来说，“流入电流等于流出电流”和“所有支路电流的代数和等于零”这两种说法是等价的。
选项：
A:正确
B:错误
正确答案:【正确】

6.选择题:列写KCL方程时，如果采用代数和等于零的形式，那么我们可以自己规定流入电流取正，也可定义流出电流取正。列写KVL方程时，如果采用代数和等于零的形式，那么我们可以自己规定升压取正，也可以定义降压取正。以上自己定义所带来的不同，其实只不过是在方程两端同时乘以+1或同时乘以-1的区别，其实方程本身并没改变。

A site in northeastern Brazil has yielded evidence of the earliest known human occupation in the Americas, approximately 32,000 years ago, according to a report by two French scientists.Although the discovery, reported in June 19 NATURE, does not resolve long-standing archaeological disputes over when and how people first arrived in the New World, the site is much older than others where human occupation has been firmly established. Several such finds in the southwestern United States date to 11,500 years ago, and a rock shelter near Pittsburgh is thought to contain evidence of use by humans 19,000 years ago; previously, the earliest known site occupied by humans in South America was 14,200 years old. –From Reader’s Choice by Baudoin, E.M. et., 1997, p. 951) site: _2) occupation: _3) resolve: _4) disputes: _5) firmly: _

1.选择题:概要写作归纳段落大意Read each paragraph below and then write a restatement of ideas in the original paragraph, or a brief one-sentence summary. Note that restatements give the same information in a different way. (10 points) Paragraph 1 Often people who hold higher positions n a give group overestimate their performance, while people in the lowest levels of the group underestimate theirs. While this may not always be true, it does indicate that often the actual position in the group has much to do with the feeling of personal confidence a person may have. Thus, members who hold higher positions in a group or feel that they have an important part to play in the group will probably have more confidence in their own performance. (3 points) Paragraph 2Like any theory of importance, that of social or cultural anthropology was the work of many minds and took on many forms. Some, the best known of its proponents, worked on broad areas and attempted to describe and account for the development of human civilization in its totality. Others restricted their efforts to specific aspects of the culture, taking up the evolution of art, or the state, or religion. (3 points) Paragraph 3There was a time when scholars held that early humans lived in a kind of beneficent anarchy, in which people were granted their rights by their fellows and there was no governing or being governed. Various early writers looked back to this Golden Age but the point of view that humans were originally children of nature is best known to us in the writings of Rousseau, Locke, and Hobbes. These men described the concept of social contract, which they said had put an end to the state of nature in which the earliest humans were supposed to have lived. (4 points)

2.选择题: Read the following paragraph and compare the summaries. Decide which is the best.Researchers in France and the United States have recently reported that baboons are able to think abstractly. It has been known for some time that chimpanzees are capable of abstract thought, but baboons are a more distant relation to mankind. In the experiment, scientists trained two baboons to use a personal computer and a joystick. The animals had to match computer designs which were basically the same, but had superficial differences. In the experiment the baboons performed better than would be expected by chance. The researchers describe their study in an article in the Journal of Experimental Psychology.

3.选择题: Read the following paragraph and compare the summaries. Decide which is the best.Sociolinguistics is concerned with the ethnography of speaking, that is, with cultural and subcultural patterns of speech variation in different social contexts. The sociolinguist might ask, for example, what kinds of things one talks about in casual conversations with a stranger. A foreigner may know English vocabulary and grammar well but may not know that one typically chats with a stranger about the weather or where one comes from, and not about what one ate that day or how much money one earns. A foreigner may be familiar with much of the culture of a North American city, but if that person divulges the real state of his or her health and feelings to the first person who says, “How are you?” he or she has much to learn about “small talk” in North American English. Similarly, North Americans tend to get confused in societies where greetings are quite different from ours. People in some other societies may ask a greeting, “Where are you going?” or “What are you cooking?” Some Americans may think such questions are rude; others may try to answer in excruciating detail, not realizing that only vague answers are expected, just as we don’t really expect a detailed answer when we ask people “How are you?” –Judith Resnick & Lanny Lester, Text & Thought, pp. 194-195
