Courses with the numbers 800 or above are open only to graduate students.Certain courses,generally those devoted to introductory material,are numbered 400 for undergraduate students and 600 for graduate students. Courses designed for students seeking a professional degree carry a 500 number for undergraduate students and a 700 munber for graduate students. A full-time graduate student is expected to take courses which total ten to sixteen credit hours. Students holding assistantships are expected to enroll for proportionately fewer hours.A part-time graduate student must register for a minimun of five credit hours. 1.In order to be eligible to enroll in Mechanical Engineering 850,a student must be ______. a.a graduate student b.a part-time student c.a full-time student d.an undergraduate student 2.If an undergraduate student uses the number 520 to register for an accounting course,what number would a graduate student probably use to register for the same course? a.accounting 520 b.accounting 620 c.accounting 720 d.accounting 820 3.A student who register for eight credit hours is a ______. a.full-time student b.graduate student c.part-time student d.non-degree student 4.A graduate student may not _____ a.enroll in a course numbered 610 b.register for only one three-hour course c.register for courses if he has an assistantship d.enroll in an introductory course 31/200答案:accb 32/200 Byrne turned the key in the heavy lock and put it calmly in his pocket.He did so much more from caution than from any kind of fear.This was the only entrance to the house,and he did not mean to be caught unawares by any danger from outside.He wondered if Tom Corbin had been as cautious the night before.Though Tom would be away for at least three days,Byrne had a strange feeling of his nearness.In the stillness he seemed to hear Tom's voice.He looked round quickly, for the tricks of hearing are the most realistic of all.But there were only the women.It seemed impossible that Tom should not be there. The girl,carrying a smoky oil lamp,led Byrne upstairs.He threw open one after another the doors along the passage.At this,the girl stopped and raised the lamp in each doorway,staring at him meanwhile.Satisfied he was the only guest,Byrne came to the last door,which the girl threw open herself. "You sleep here,sir" she said,giving him the lamp."Your friend slept here too.It's our most comfortable bed." "Good night,miss," he said politely. Her lips moved in reply, but he did not catch the words.Her eyes never for a moment left his face.He stepped in,and as he turned to close the door she was still standing there motionless.He paused,and in the silence he thought he again heard the sound of Tom's voice.The sound ferrified him now ,not only because it seemed much nearer but also because he imagined a note of warning in it. 1.Why did Byrne take the key with him? 2.We know from the passage that Tom Corbin_____. 3.Byrne was surprised when he turned round because_____. 4.Why did Byrne look inside each room? 5.Although Byrne politely wished the girl good night_____. 6.What made Byrne very frighteded? There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution. By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed. The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism. 1.The study of the effects of salt on high blood pressure was carried out ______. 2.The main difference between "S" and "R" rats is their ______. 3.We can infer from the article that sodium 22 can de used to ______. 4.The most beneficial results of the research might be ______. 5.Which of the statements best relates the main idea of this article? 34/200 1.The expression "he or she is like fish out of water"suggests ______. 2.In order to identify with the new environment,some people may ______. 3.Which of the following statements is true according to the author? 4.Newcomer may worry about ______. 5.When the foreign visitor is immersed in new problems he finds hard to cope whith,he is most likely to feel ______. 35/200 Passage 7 Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed. Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white counterparts. 1.The passage is mainly discussing __________ . 2.______ is one of the factors that tend to promote social change. 3.According to the passage, which of the following is NOT true? 4.The expression "greater tolerance"(paragraph 1) refers to _____ . 5.Social change is less likely to occur in a society where people are quite similar in many ways because ________ . |
