1.________in the heavy rain ,the man got wet through and shivered with cold.A.having caught B.caught(一直没弄清到底是用完成时还是过去式的现分)2.The policeman caught yhe theif by ___arm .A.a B.the C./3.It is reported that more and more people prefer going travelling during the Spring Festival_____at home .A to staying B.rather than stay (不是prefer to do 后才用rather than do )4.Today ,we will discuss a number of cases ______beginners of English fail to use the language properl

第一题悬A，你想啊，caught是catch的过去式或过去分词，怎么能做主语呢，所以选A .
第二题选B，这句话的意思是：警察用手臂抓住了小偷。
第三题选B，prefer doing sth 后也可接rather than do sth,总不能选A吧，to后要接动词原形，对吧。
第四题，case是先行词，用where引导。

1表结果的用过去时的分词
2习惯用法
3prefer doing to doing
4:因为先行词是cases，抽象地点名词。

1.B:A错，应该是被动。(I was caught)in the rain
2.B:catch sb by the arm 是固定用法
3.A:prefer doing to doing固定用法，prefer to do rather than do
4.B:先行词是case,用where

1.A解析：用完成时，强调对现在的影响，过去式没有这一用法。
2.B
3.A
4.A

1、B 此处caught为被动语态形式,翻译为男人被困在雨中,选A不对,应改为having been caught
2、B by the arm为固定搭配
3、A prefer doing to doing 和perfer to do rather than do
同意,都是固定搭配
4、B 这里主要看先行词,若先行词为situation、case时都用where.

1.B 选项A 形式错误，应该是having been caught.
2.B
3.A perfer diong to doing
4.B 先行词是case时用where 引导

A C A B
