If an animal is moved from its home in the tropics (热带地区) to a cold climate, it will die if it is not kept warm. And animals【C1】________to cold climates will die if they are moved to the tropics. Many plants, too, will die if they are removed from the place where they【C2】________grow and are transplanted (移植) into an unfamiliar soil. Almost every species is adapted to life in a particular place by its organs and their functions and by【C3】________habits. The specialized adaptation has great advantages, for it【C4】________many organisms to survive under different conditions. It also has disadvantages, for it means that the life of most species is controlled by【C5】________conditions.
Living things are not【C6】________over the earth freely; most species have definite habits for living places. Ecology is the study of how organisms live in their environment This means finding out how an organism survives and【C7】________in certain surroundings. By environment we mean not only the soil and the climate but the living things of the same species and other species, plant or animal Most living things are【C8】________to their environment Some can【C9】________certain features of their environment to suit themselves; a beaver (海狸), for example, can make ponds by building dams, many birds and insects can build elaborate nests to provide【C10】________for their young. But these skills are restricted and highly specialized. Most organisms must adapt their bodies to fit in with their surroundings, and since they can adapt only for particular surroundings, they are found only in places where they can live successfully with the least effort.

1.【C1】
D
解析：此处需要形容词或动词的分词来构成animals的后置定语，且可与介词to搭配。本句与上一句的内容相反，对比两句的结构和内容，可以推断空白处应为accustomed一词。
2.【C2】
A
解析：此处需要副词，作where从句里的状语。removed from…into…结构表明定语从句里的内容与into后的unfamiliar相反，由此可确定本题答案为normally。
3.【C3】
J
解析：此处需要形容词或相当于形容词功能的词，作habits的定语。本句是对前三句提到的例子的概括，结合前三句的内容可确定答案为permanent。
4.【C4】
M
解析：空白处前为人称代词it，后为名词organisms，提示此处需要动词充当for从句中的谓语，而且该动词应该是第三人称单数形式，并可与to搭配，词库中只有enables合适。
5.【C5】
O
解析：此处需要形容词或相当于形容词功能的词，作conditions的定语。本句作为末句，与本段的主题密切相关，指出物种的生命受制于它们生长所在地的条件，词库中只有local可表达这个意思。
6.【C6】
E
解析：此处需要形容词或动词的分词形式，与前面的are not构成完整谓语。分号后面的分句是对前一个分句的进一步说明，空白处前已有not，因此可推断空白处的单词与第2个分句中的have definite habits意思相反，由此可确定答案为scattered。
7.【C7】
I
解析：此处需要一个第三人称单数的不及物动词，与survives并列作how引导的从句的谓语，它应该是与survive类似的动词，用于描述生物的习性，故答案为reproduces。
8.【C8】
K
解析：此处可能需要形容词或名词，作are的表语；也可能需要动词分词与are一起构成完整谓语。前文第1段最后一句提到大部分物种的生命受制于环境，此句属于前文的复现，所填词应与第1段最后一句中的controlled同义，词库中只有slaves可表达这个意思。
9.【C9】
H
解析：空白处前为can，后为名词features，提示此处应填及物动词，且为原形。下文海狸筑坝等例子是为了说明本考点所在句子的观点的，因此根据例子的内容可确定答案为alter，表明生物改变环境来适应自己。
10.【C10】
B
解析：此处需要名词，作provide的宾语。句中的不定式to provide ________for their young是build nests(筑巢)的目的，由此可判断答案为shelter。
