learning about language

第一节 单项选择

1. Seeing the big crowd coming towards him, he started to run down the hill, but ______ and went down on his hands and knees in the melting snow.

A. slipped B. skied C. signalled D. sank

【考点】考察动词词义辨析以及上下文理解

【答案】A

【解析】本题考察的动词词义辨析。A滑倒；溜...；B滑雪，滑冰；C发信号；用动作示意；D沉没；下沉；句意：看见一大群人朝他跑了过来，他开始朝山下跑去，但是滑倒了，然后就在融化的雪里手和膝盖着地滚了下去。根据后面半句中的went down on his hands and knees in the melting snow可知他是从山上滚了下去，也就是说他要先滑倒在地。故A正确。

【试题延伸】本题考察的都是以字母s开头的动词词义辨析，首先可以从句意着手，看懂句意是解答此类题目的关键，其次四个选项的意思也要了如指掌。这对于平时学生的学习仔细度提出了要求。

2. The old rules have to be ______ because they only applied to the circumstances that existed when they were made a hundred years ago.

A. developed B. established C. observed D. revised

【考点】考察动词词义辨析及上下文串联

【答案】D

【解析】考察动词词义辨析develop发展，establish建立，成立；observe观察，庆祝，遵守；revise修订，修正；句意：这些就的规则不得不被修订了，因为他们只适用于100年前这些规则被制定的时候所存在的情况。根据句意可知这些规则是很久之前就制定的，所以已经不适应现在的情况了，所以需要修改。故D正确。

3. Though having lived abroad for years, many Chinese still the traditional customs.

A.perform B.possess C.observe D.support

〖答案〗C

〖考点〗考查动词意义。
