三、考查非谓语动词完成式的用法

非谓语动词(不定式、动名词和现在分词)的完成式主要表示发生在谓语动作之前的动作。做题时要注意根据题干所提供的语境来推断这种先后关系。如：

1. The storm left, _____a lot of damage to this area.

A. caused B. to have caused C. to cause D. having caused

分析：答案选D。因The storm与cause是主动关系，排除选项A;不定式作状语，前面通常不用逗号，排除B和C;因暴风雨给这个地区“造成损失”是在“结束”之前，所以用完成式。

2. More and more people are signing up for Yoga classes nowadays, _____　advantage of the health and relaxation benefits.

A. taking B. taken C. having taken D. having been taken

分析：答案选 A。因people与take advantage of是主动关系，排除选项B和D;take不会发生在谓语are signing up之前，不用完成式，排除C。

四、考查非谓语动词用作伴随状语

在通常情况下，表伴随情况的应用现在分词。如：

1. “You can’t catch me!” Janet shouted, _____away.

A. run B. running C. to run D. ran

分析：答案选B。现在分词作伴随状语。

2. He glanced over at her, ______ that though she was tiny, she seemed very well put together.

A. noting B. noted C. to note D. having noted

分析：答案选 A。因为he与note是主谓关系，且note与谓语动词glanced的动作同时发生，所以用现在分词的一般式作伴随状语。

3. Daddy didn’t mind what we were doing, as long as we were together, _____fun.

A. had B. have C. to have D. having

分析：答案选 D。用现在分词表伴随情况。

说明：有时过去分词也可表伴随(注意过去分词同时还表被动关系)，但高考很少考查此用法。如：

He came in, followed by his wife. 他走了进来，后面跟着他的妻子。
