| 第1、2、3、4题：Because we can feel that things are heavy, we think of weight as being a fixed quality in an object, but it is not really fixed at all. If you could take a onepound packet of butter 4, 000 miles out from the earth, it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4 000 miles out into space? The reson is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4 000 miles from the centre (in other words the radius(半径)of the earth is 4 000 miles). When we took the butter 4 000 miles out, it was 8 000 miles from the centre, which is twice the distance. If you double the distance between two objects, their gravitational attraction decreases(减少)two times two. If you treble(翻三倍)the distance, it gets nine times weaker(three times three). If you take it four times as far away, it gets sixteen times weaker(four times four)and so on. 69. The best title for this passage is. A、The Earth Weight B、Weight in Space C、Changing Weight on the Earth D、Weight on and off the Earth 70. We can feel things are heavy because. A、weight is a fixed quality in an object B、they are far away from the centre of the earth C、of the earth's strong attraction for them D、they are not taken away from the surface of the earth 71. If the distance between two objects is shortened by half, their gravitational attraction will. A、double B、become four times stronger C、be the same D、get four times weaker 72. If an object weighed one pound 8 000 miles above the earth, it would weighon the surface of the earth. A、6 pounds B、4 pounds C、9 pounds D、1/9 pound |

| 第6、7、8、9题： In ancient(古代) time the most important examinations were spoken, not written. In the schools of ancient Greece and Rome , testing usually consisted of saying poetry aloud or giving speeches. In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study of the subject. This custom exists today as part of the work of testing candidates（候选人）for a master's or doctor's degree. Generally, however, modern examinations are written. Two types of tests are commonly used in modern schools. The first types sometimes called an objective (客观性) test, it is intended to deal with facts., not personal opinions. To make up an objective test the teacher writes a series of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have mot learned the material properly. The student has just one task: he must recognize the correct answer and copy its letter or number on his examination paper. For testing a student's memory of facts and details, the objective test has advantages. It can find out a great deal about the student's range of knowledge. For testing some kinds of learning, however, such a test is not very satisfactory. A lucky student may guess the correct answer without really knowing the material. 36. The passage is mainly about ________. A. examinations in the ancient times. Ｂ．modern examinations. Ｃ．how to do well in an examination. Ｄ．setting questions for an examination 37. The objective test is not very satisfactory because _______. A. it is easy and quick to score. B. the teacher can find out a great deal about the student's range of knowledge in a short time. C. it shows how deeply the student has thought about the subject. D. it contains element of luck. 38. Which of the following statements about the objective test is true? Ａ．Examinations in modern times are written, while in ancient times they are spoken. Ｂ．The objective test has advantages for testing a student's memory of facts and details. Ｃ．The objective test is the only way to test a student's memory of facts and details,. Ｄ．Each objective question has more than one correct answer. 39. The next paragraph will probably deal with ___________. A. the other type of examination B. the advantages of the objective test C. how students guess the correct answer without really knowing the material D. examinations in the ancient times |
