A.while performing B.performing C.
while I was performing
D.
to perform
A.while performing B.performing C.
while I was performing
D.
to perform
选C.
句意：
当我正在实验室做实验时,天开始下大雨了.
关键信息见【】
While【 I 从句主语】 was performing experiments on the laboratory ,【it 主句主语】started to rain heavily.
即,主句和从句主语不一致,那么,各自的主语必须分别而出现,而不能用现在分词等非谓语动词形式,因此,A,B,D都可以排除.
祝你开心如意!
再问： 麻烦问下A和B的区别是什么
再答： A.while performing 经常被看做是【while引导的时间状语从句的省略形式】。但是，主句主语和从句主语相同时才能用这种省略形式。例如： While walking along the bank of the river, Tom suddenly heard a cry for help. While walking=While 【Tom was 】walking B.performing 单纯的【现在分词形式】，多表示主动或正在进行的动作。 不能选这两个的直接原因是，从句主语【it】，不是【performing】这个动作的发出者或执行者。 【performing】这个动作的发出者或执行者只能是【人】，即C项中的主语【I】
