答案： to escape being burned不定式作目的状语。

3. O'Neal works hard.He is often seen ＿＿＿heavily before his teammates start.
A.sweated B.to be sweated C.sweating D.being sweated

4. I remained _______ long after I had been told the story.
A. puzzling B. puzzled C. being puzzled D. to be puzzled
答案： B
解析：puzzled 表主语感到迷惑不解的，puzzling 表令人迷惑不解的，beingpuzzled强调正在进行的被动动作，to be puzzled表在主句谓语之后发生。
5. I can hardly imagine Peter_______ across the Atlantic Ocean in 15 days.
A.sail B.to sail C.sailing D.to have sailed
答案： C
解析： Peter为逻辑主语，与sailing构成复合结构，作imagine的宾语。
6. I _____(drive) along the quiet road at forty miles an hour, and then an old man suddenly started to cross the road in front of me.（填空练习）
答案：was driving
解析： 因句中有连词and，所以and 之前必须是一个并列关系的分句。
【小知识】复合结构动词不定式
复合结构不定式：由for + 名词（或代词宾格）+ 动词不定式即构成复合结构的动词不定式。
其中for本身无意义。for后面的名词或代词是不定式的逻辑主语，这种不定式在句中可作主语、表语、宾语、定语或状语，如：It is very important for us to get everything ready for the harvest.
当作表语用的形容词表示不定式的逻辑主语的性质或特征时，就用介词of而不用for引出不定式的逻辑主语，这些形容词一般有good, nice, kind, wise, silly, stupid, foolish, right, wrong, careless, impolite等，如：It is very kind of you to help him every day.
