题目解答

答案

解析

考查要点：本题主要考查语法填空中的比较级、非谓语动词、冠词、时态等知识点，需结合上下文语境判断词性变化及固定搭配。

解题思路：

  1. 比较级：注意形容词比较级的构成及修饰对象；
  2. 非谓语动词：判断动词与逻辑主语的关系（主动/被动）；
  3. 固定搭配：如result in、an average of；
  4. 时态语态：根据时间状语或语境选择正确时态。

1. Humans need 1 (little)sleep than other mammals

比较级用法：little的比较级是less，表示“更少的睡眠”。

2. yet 2 (they)slumber is more efficient

代词用法：需用形容词性物主代词their修饰名词slumber。

3. said 3 (research)at Duke University

名词复数：researcher是可数名词，表示“研究者们”需用复数researchers。

4. humans sleep for shorter periods of time 4 (compare)to other animals

非谓语动词：humans与compare是被动关系，用过去分词compared作状语。

5. A deeper stage of sleep,5 (call)rapid eye movement sleep

非谓语动词：stage与call是被动关系，用called作后置定语。

6. unique in 6 (have)shorter, higher quality sleep

动名词用法：介词in后需接动名词having。

7. found 7 humans can prosper

宾语从句：从句完整且不缺成分，用连接词that。

8. an average of seven hours of sleep

冠词用法：average前有an修饰，因a发音为元音开头。

9. habits 9 (evolve)during prehistoric times

时态用法：时间状语prehistoric times提示用一般过去时evolved。

10. result 10 better sleep

固定短语：result in表示“导致”，需填介词in。
