1、2022年高三二模考试英语汇编 阅读C篇 含答案(崇明)(C)Lots of bacteria can grow in the seemingly unfriendly environment under glaciers(冰川), a region formerly considered free of much biology. This finding by glaciologists working in Switzerland could help solve some puzzles of the last ice age and point the way for finding
2、 life on other planets.Bacteria with odd lifestyles have been under increasing study lately, with most research focused on the species which prefer hot homes. The new study shifts attention to the other end of the thermometer(温度计). The exciting thing is the idea of pushing the window of acceptable b
3、acterial environments a little bit farther open.Researchers have previously collected small numbers of bacteria from ice in Antarctica and Greenland, but they could not determine whether these were active bacteria or just frozen cells blown in by wind. In contrast, the earth beneath two Swiss glacie
4、rs harbors large colonies of bacteriahundreds of millions of cells per gramthat appear to be growing at 0.Scientists followed upon these findings by taking samples of ice, water, and earth at two mountain glaciers. They found that earth beneath the glaciers contained much larger populations of bacte
5、ria than did surface and inner part of ice. Those findings indicate that the bacteria were growing at the bottom of the glacier and are not something washed in while the scientists drilled through the ice.Looking at the bacteria under a microscope(显微镜), the researchers found that many were in the pr
6、ocess of dividing, and healthy under the ice. The bacteria might break down minerals and plant remains originally buried beneath the glacier or later washed in by water going slowly through the ice, scientists say.“Some of the assumptions we have made in the past now must be seriously questioned,” s
7、ay researchers. “If bacteria can live under glaciers on Earth, why not on other planets? The new study points out in many ways that the bottoms of glaciers are probably quite good environments from the point of view of bacteria. So, maybe the bottom of the ice sheets on other planets would be a sens
8、ible place to try if youre going to look for life on them.”72. What is special about the new study on bacteria? A. It focuses on the bacteria in hot environments. B. It opens the windows of the bacterial labs wider. C. It pays more attention to the bacteria in the thermometer. D. It changes scientis

The drills used by scientists are free of bacteria. C. Many of the bacteria are in the process of dividing. D. The earth beneat
10、h the glacier contains more bacteria.74. From the passage we can learn that _. A. bacteria disappear in the inner part of ice B. bacteria must be also alive on other planets C. bacteria can grow in extreme weathersD. bacteria grow by breaking themselves down75. The passage is mainly about the possib

As the Lancet put it recently, “When we try to describe faces
12、 precisely, words fail us, and we resort to identikit (拼脸型图) procedures.”Yet, according to one authority on the subject, we can each probably recognize more than 1,000 faces, the majority of which differ in fine details. This, when one es to think of it, is a tremendous feat, though, curiously enoug
13、h, relatively little attention has been devoted to the fundamental problems of how and why we acquire this gift for recognizing and remembering faces. Is it an inborn property of our brains, or an acquired one? As so often happens, the experts tend to differ.Thus, some argue that it is inborn, and t
14、hat there are “special characteristics about the brains ability to distinguish faces”. In support of this, they note how much better we are at recognizing a face after a single encounter than we are, for example, in recognizing an individual horse. On the other hand, there are those, and they are pr
15、obably in the majority, who claim that the gift is an acquired one.The arguments in favor of this latter view, it must be confessed, are impressive. It is a habit that is acquired soon after birth. Watch, for instance, how a quite young baby recognizes his mother by sight. Granted that his other sen
16、ses help the sound, his sense of smell, the distinctive way she handles him. But of all these, sight is predominant. Formed at the very beginning of life, the ability to recognize faces quickly bees an established habit, and one that is, essential for daily living, if not necessarily for survival. How essential and valuable it is we probably do not appreciate until we encounter p
