Climate, more than any other single factor, determines the distribution of life on Earth. Climatic boundaries establish the limits within which organisms can survive. Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions are likely to occur.[8]In the harsh conditions of the tundra, for example, some low growing and a few flowering plants all hug the ground for shelter from icy winds. Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution. Others, such as bears, are flexible enough to adapt to a broad range of climates; ocean-dwelling organisms are just as sensitive to climatic changes — in this case temperature and salinity — as land animals.[10]Reef corals can survive only in clear warm seawater. Certain organisms are so sensitive to changes in their environment that their presence can be taken as an index of sea temperature. Human beings are among the least specialized of all animals and can live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.
7. What is the passage mainly about?
8. According to the passage, why do some plants on the tundra hug the ground?
9.What can be inferred about the camel and the penguin from the passage?
10.Which of the following may die first if the seawater gets colder?
选项
A、They usually do not suffer from climate change.
B、They are used to living in dry and cold climate.
C、They are able to adapt to different climates.
D、They may not survive if they are moved to a different climate.
答案
D
解析
推断题。短文开头处的Climate boundaries…表明,organisms(生物体)只有在一定的气候区域内才能够生存(survive),下文分别以不同的动植物进行说明。在提到骆驼(camel)和企鹅(penguin)时说到,the camel和the penguin是如此特别,以至于它们的分布区域极其有限(limited)。结合上述分析可知,如果把the camel和the penguin移至不同的气候中,它们很可能无法survive,故答案为[D]。
