对比去理解not only. but also.也就是说,as well as 也有“不但.而且.”的意思只不过与not only. but also.的侧重点不同也就是说 not only A but also B= B as well as A 意为“不但A,而且B”这也就有了,not only. b...as well as要放在句首时后加动词什么形式呢as well as 如果放在句首，就不是“不但....而且”的意思了，这时，一般不在考虑主谓一致的问题，这时的意思是“除了......之外，还....”，相当于Besides.例如：As well as French, he knows other two foreign languages.另外，如果说，放在句首的as well as后面一定要接动词的某种形式的话，请记住，必须接动名词形式，也就是-ing。如：As well as breaking his leg, he got his head hurt.放在句中也一样，He sings as well as playing the piano.
