过去分词作状语，用来说明谓语动作发生的背景或情况，通常有以下几种题型：

1.作原因状语，相当于一个原因状语从句：

【名题14】

______ , the young man is healthy and strong..

A. Fully developedB. Fully growing C. Full developingD. Full grown

【解析】 本题考查非谓语动词作状语。首先，分词前要用副词来修饰；其次，grow是不及物动词，可以说grow quickly（长地快）、grow old （变老），但fully growing就不和逻辑了。而developt （使发展）。A和句子的主语是被动关系，说明了该年轻人身体强健的原因是因为得到了全面发展。答案为A。

【名题15】

______ in thought, he almost ran into the car in front of him.

A. LosingB. Having lostC. LostD. To lose

【解析】 Lose 是及物动词， 意思是“专心致志于…”, 后接反身代词； lost in thought源于lose oneself in thought。答案为C。

2.表示一个假设情况，相当于一个条件从句：

【名题16】

______ in this way, the situation doesn’t seem so disappointing...

A. To look atB. Looked at C. Looking atD. To be looked at

【解析】 题中的look at 是及物动词，而句子的主语situation 和 look at 只能是被动关系；D项虽为被动体，但不定式放于句首时只能作目的状语，其语法功能和题义不符。答案为B。

【名题17】

_______ with developed countries, we still have a long way to go.

A. To compare B. ComparedC. Comparing D. Being compared

【解析】 本句可以转换为复合句“If we are compared with developed countries, we still have a long way to go.”由此得知句子的主语we和compare之间属于被动关系，所以要用过去分词。答案为B。

3. 一般情况下非谓语动词作状语时，要求非谓语动词表示的动作和谓语动词的主语相同，但也有少数分词短语实际上已经成为固定结构，表示说话人对说话内容所持的态度。如：

【名题18】

______the general state of his health, it may take him a while to recover from the operation.

A. GivenB. To give C. GivingD. Having given

【解析】 given在此意为“鉴于”、“考虑到”。这种评说性的独立成分作状语，其逻辑主语不要求和句子的主语保持一致。这种情况下，分词短语的逻辑上的主语和句子的主语是不一致的，可以看作是一种独立成分.例：

⑴ Judging from what you say, he ought to succeed.

⑵ Considering his age, the child reads well.

⑶ Taken as a whole, there is nothing wrong.

⑷ Given their inexperience, they have done a good job.

答案为A。

4. 分词作状语时，有时前面可以加上一个连词。连词than, as, once, if, unless, though, even if等之后，均可以接一个过去分词作状语，这时，分词的逻辑主语是分词的动作对象。

【名题19】

The research is so designed that once _______nothing can be done to change it.

　　A. begins B. having begunC. beginning D. begun

　 【解析】本题考查的是过去分词作条件状语从句时的用法.在这儿once begun可换成once it is begun,故最佳答案是D项.

【名题20】

When _______, the museum will be open to the public next year.

　　A. completed B. completing C. being completed D. to be completed

　 【解析】该题考查过去分词充当时间状语的用法.同样把when completed还原成when it is completed便可知最佳答案为A.

【名题21】

______ who she was, she said she was Mary’s cousin.

A. AskedB. When asked C. When asking D. Asking

例：⑴ Once recovered, he went all out to do his work.

⑵ Though beaten by the opposite team, the players didn’t lose heart.

⑶ If carefully done, the experiment will be successful.

要学习掌握非谓语动词作状语，就必须牢记不定式、现在分词和过去分词的基本属性，并据此从句子的整体结构去理解句子的含义。只有这样，才能有效地排除干扰项，并作出正确选择。
