我来补答

这是2004年4月自考英语语法试题第8小题.
正确答案就是A.
其实,也不难理这是【状语从句+省略结构】.语法中状语从句部分是这样说的：
在时间、条件、方式、比较、让步等状语从句中,如果从句主语与主句主语相同,或者从句主语是it时,从句主语与谓语动词的一部分（经常是be动词）经常省略.例如：
While crossing the road,Tom was hit by a car.
=While Tom was crossing the road,he was hit by a car.
Come to school early【 if possible=if it is possible】
故,结合语境和时态,原句完整形式应该是：
Whenever the professor explained something,she kept smiling and nodding her head from time to time （as if/as though she was）understanding every word of his lecture.
至于like,作“像.一样”,经常搭配：be/look/seem like;feel like【介词】.
The weather looks like【介词】 clearing up.天气好像会放晴.
Tom is like【介词】 his father in looks.汤姆的相貌像他父亲.
也可以做连词,引导从句,但是,词典上明确注释：informal【非正规用法】,即是as用法误用而形成的.如：
Like 【连词,informal】I said(=as I said),you're always welcome to stay.
正如我以前所说过的,我永远都欢迎你留下.
She acts like【连词】she owns the place .她的举动就像那地方是她的一样.
It was just like you said.
情况正如你所说的那样.
