1、山东专升本英语(阅读)模拟试卷 1 及答案与解析0 The making of glass is a very old industryat least 4 500 years old. Glass has many extraordinary qualities and it is frequently being used in new ways.One of the most interesting new uses for glass is in telephone communication Scientists have developed glass fibres as thin
2、 as human hair which are designed to carry light signals. When the light reached the other end, it is first changed into electrical signals, which are in turn converted into sound messages.Called light wave communication, the new system was used successfully in an experiment in Chicago in 1977. Duri
3、ng the experiment, two glass fibres were able to carry 672 conversations at the same time. The lightwave cable, containing 144 glass fibres, has the capacity to carry 50 000 conversations at the same time.The lightwave communication system has two important advantages. First, the glass fibre cables
4、are smaller and weigh less than copper cables. Second, they cost less. Perhaps it can be said that telephone communication has entered the age of light.1 One of the extraordinary qualities of glass is that it can carry_.(A)light signals(B) electrical signals(C) sound signals(D)any signals2 Before we
5、 can hear a message on the telephone using the new system, _.(A)electrical signals must first be changed into light signals and then into sound(B) light must first be changed into electrical signals and then into sound(C) the light signals have to be turned directly into sound messages(D)electrical
6、signals have to be changed directly into sound messages3 According to the passage the new telephone communication system_.(A)had been repeatedly experimented on before 1977(B) was first put into actual use in 1977(C) had been used within very limited scope before 1977(D)was put on experiment success
7、fully in 19774 From the passage, we can tell that people prefer glass fibre cables to copper cables because_.(A)glass fibres are less expensive(B) glass fibres are easier to make(C) glass fibres deliver messages directly(D)glass fibres are more up to date5 Which of the following statements best expr
8、esses the main idea of the passage?(A)Glass is very useful because it has many unusual qualities.(B) Light signals have changed the use of glass in industry.(C) The use of glass fibres to carry telephone messages is an interesting new development(D)Glass fibres have reduced the cost of telephone com
9、munication5 Data from the pioneer spacecraft of the National Aeronautics and Space Administration(NASA)apparently prove the theory that the searing 900-degree Fahrenheit surface temperature of Venus is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a green
10、house effect is created when energy in the form of sunlight easily passes through a planets atmosphere, warms its surface, and is converted to heat radiation that is then held in by the atmosphere. The orbiting spacecraft sampled Venus atmosphere from top to bottom, enabling NASAs scientists to esta
11、blish the exact amount of sunlight absorbed at various places in the planets atmosphere and on its surface.Measurements of atmosphere composition, temperature profiles(变化曲线), and radiative heating predicted Venus surface temperature very accurately. The planet is closer to the Sun than is Earth, and
12、 it has a relatively thin atmosphere like Earths, but Venus atmosphere consists of more than ninety percent carbon dioxide, compared to less than four percent in that of Earth. Because of its higher percentage of carbon dioxide, Venus atmosphere traps much more heat radiation than does Earths. Thus,
13、 the Venus researches are believed to be important to the understanding of possible adverse(不利的)effects on Earths agriculture and sea levels that could result from the long-term use of fossil fuels, which add carbon dioxide to the atmosphere.6 Which of the following would be the best title for the p
14、assage?(A)New Theory(B) Measuring Planetary Temperatures(C) The Voyage of Pioneer Spacecraft(D)The Greenhouse Effect on Venus7 According to the passage, what happens to heat radiation on Venus?(A)It is neutralized at the planets surface.(B) It is trapped by the atmosphere.(C) It creates energy.(D)It
15、 circulates evenly.8 According to the passage, how does the atmosphere of Venus differ from that of Earth?(A)It contains much more carbon dioxide.(B) It holds significantly less moisture.(C) It is four percent thinner.(D)It traps less heat radiatioa9 From the passage it can be inferred that the burn
16、ing of fossil fuels on Earth may cause_.(A)more carbon dioxide to enter sea water(B) more sunlight to reach the Earths surface(C) the atmosphere to become thinner(D)the planets temperature to change10 According to the passage, data from the Venus study can be used to_.(A)predict changes in the plane
17、ts orbit(B) predict future agricultural problems on Earth(C) test the efficiency of a spacecraft(D)test a theory about more efficient greenhouse10 Scholars and researchers have tried to discover what personality characteristics go along with success in intercultural experiences. Their findings have
18、often been unclear or incomplete. But three characteristics stand out in their reports: patience, a sense of humor, and the awareness of being unclear.Patience, of course, is the ability to keep calm even when things do not go as one wants them to, or hopes they will, or has even been sure they will
19、. Impatience sometimes brings improvements in relations with other people, but usually it does not.A person with a sense of humor is less likely to take things too seriously and more ready to see the humor in her own reactions than is a humorless persoa The value of a sense of humor really needs to
20、be paid more attention to.“The awareness of being unclear“ is a more difficult concept than patience or a sense of humor. Foreigners often find themselves in situations that are unclear to the newcomers. That is, they do not know what is happening in the situatioa Perhaps they do not understand the
21、local language well enough, or they do not know how some system or organization works, or they cant be sure of different peoples roles in what is going on. “Its like I just got here from the moon,“ a Chinese graduate student who newly arrived in the United States said, “Things are just so different
