1、银行校园招聘考试英语部分专项练习（一）Part I Reading Comprehension Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A., B., C. and D. You should decide on the best choice and mark the corresponding
2、 letter on the Answer Sheet with a single line through the center.Questions 1 to 5 are based on the following passage:If the salinity of ocean water is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic proc
3、esses that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporationconversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystal
4、s of salt would be left behind; this, by the way, is how much of the table salt we use is actually obtained.The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of
5、high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.Normally, in tropical regions where the sun is very strong, the ocean salinity is so
6、mewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.A third process by which salinity may be altered is associated with the formation and melting
7、 of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it well tend to decrease the salinity of the surrounding water. I
8、n the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of oceans of the world.1. What is the main topic of the passage?A. Where do we get
9、 our table salt?B. Oceanic salinity in tropical regionsC. Three basic processes that alter oceanic salinityD. Variations of salinity in different parts of the ocean2. According to the author, the oceanic salinity is usually lower in _.A. tropical regionsB. coastal regionsC. places in which warm curr
10、ents and cold currents meetD. the Antarctica3. All of the following are processes that decrease ocean salinity except _.A. precipitation B. runoff C. melting D. evaporation4. What does the word “subtraction in the fourth line of the first paragraph mean?A. reduction B. influx C. transformation D. fr
11、eezing5. Which of the following is NOT a result of the formation of ice in oceans?A. The surrounding water sinks.B. The water becomes denser.C. Water salinity decreases.D. The surrounding water becomes colder.Questions 6 to 10 are based on the following passage: More than a century ago, the relation
12、ship between glacial ice and the amount of water in the ocean basins was first seen. When the great ice sheet covered vast land areas, the sea level was lowered because the normal return of water from land to the ocean was reduced. As a result, the sea level rose as Ice Age glaciers melted allowing
13、the melted waters to flow into the ocean. If all the glacial ice on the surface of the earth today should melt, the sea level might rise by more than 150 feet. Shoreline variations are also produced through elevation or depression of the land. During times of glacier formations the great weight of t
14、he ice slowly depressed the earths crust. Removal of the weight through glacier melting allowed the slow return of the crust to its former position. Changes in the Great Ice climates from cool and wet to warm and dry produced climate changes far from the glaciated area. For example, at times of cool
15、-wet glacial climates, levels of inland lakes rose, in contrast to the depression of sea level. During the warm-dry interglacial climates, lake levels were lowered. The ancient lake Bonneville, largest of the glacial lakes in Western United States, once covered more than 20,000 square miles. It had
16、a maximum depth of more than 1,000 feet. Great Salt Lake in Utah is the shrunken remnant of this once large lake.Although the first time that early man walked on the earth is uncertain, he is largely a product of the Great Ice Age. Present information shows that during this time he evolved rapidly both physically and culturally. His most primitive tools and skeletal remains ha
