Question

【题目】阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Today, many people are worried about endangered species. But isn't it just normal for some animals to die out?

The situation today is different from 【1】 of the past. In the past, animals died out over a long period of time. When animals died out in the past, it was usually because of the weather or other 【2】 (nature) causes.

What is happening today is 【3】 ( total) different. We are killing millions of species in a short time. The result is that we are killing our future, because so many species 【4】( kill) in such a short time that even 【5】 fittest can't survive. In fact, there won't be enough species to choose from. Without enough animals and plants, evolution cannot function and nature will get 【6】( bad) instead of better.

Many of the species 【7】( disappear) on earth are unknown and few people even know that they are dying out. These animals and plants started to live on earth long 【8】 us and we have no right to kill them. We may also need these species in the future. We must try to keep the endangered species alive. If we allow these species 【9】(die)out, we are in fact becoming endangered 【10】(our).

Answer 1

【答案】

【1】that

【2】natural

【3】totally

【4】are (being) killed

【5】the

【6】worse

【7】disappearing

【8】before

【9】to die

【10】ourselves

【解析】

这是一篇说明文。由于人类的捕杀，大量物种灭绝，如若人类继续捕杀，自然将会继续恶化。这为人类保护濒危物种敲响了警钟。

【1】考查代词。句意：当今之形势不同于以往之形势。结合句意和句子结构可知，此处应用that代指上文的the situation，故填that。

【2】考查形容词。此处应用nature的形容词修饰名词causes，故填natural。

【3】考查副词。此处应用total的副词修饰形容词different，故填totally。

【4】考查时态和语态。此处是原因状语从句的谓语动词，由前文的is判断为一般现在时，主语species和kill之间是被动关系，故用一般现在时的被动语态，也可以用现在进行时的被动语态，主语是复数，故填are (being) killed。

【5】考查冠词。fittest为fit的最高级形式，前面须用定冠词the，故填the。

【6】考查形容词比较级。此处应填形容词作为get的表语，由better判断用比较形式，故填worse。

【7】考查非谓语动词。分析句子结构可知，此处是非谓语动词作后置定语，species和disappear是逻辑上的主动关系，故用现在分词作后置定语，故填disappearing。

【8】考查介词。句意：在人类之前，这些动植物就在地球上生活很久了，我们无权杀掉他们。结合句意可知，此处考查介词before“……之前”，故填before。

【9】考查短语。此处考查短语allow sth./sb. to do sth.“允许某人/某物做某事”，故填to die。

【10】考查代词。句意：事实上，我们自身也变得岌岌可危。结合句意可知，此处用反身代词ourselves，表示强调，故填ourselves。

第一小题考查that作为代词的用法

that指代同类异物，一般用于前后进行比较的句子中，如果比较的对象是可数名词复数形式，就用those。

例如：

The water in the cup is hotter than that in the pot. 杯子里的水比罐子里的水热。

The cars made in china are better than those made in japan.中国生产的车比日本生产的车好。
