我们英语老师提到:than做连词引导比较状语从句,并造了以下句子为例: parents always have much more expectation than I can do. 但仔细读后发现 为什么不能是做介词 后接than what I can do.请英语专业人士帮忙解答,谢绝从网上COPY答案
一楼回答看不懂……what I can do 是一个句子吗?只是一个名词性的从句吧?I can do 才是一个句子吧?
所谓连词,就是要连接两个平行成分。 parents always have much more expectation than I can do. 这个句子中,than做连词,就是连接两个句子: (parents always have much more expectation) than (I can do).
楼主想改成parents always have much more expectation than what I can do.我觉得是可以的,而且这时候than的确变成介词:“与……相比”,因为than的前后已经不再是平行句式,而仅仅是more expectation与what I can do在相比。
再看以下例子:
That building is more magnificent than I thought. 那座大楼比我想象的更宏伟。 This multi-storied building is more grand than what I imagine. 这座大楼比我想象的更宏伟。
