How do you think
senior high school will be different from junior high school?
What do you think the principal will talk about in his speech?
这是高中英语新教材译林版必修1第1单元的两个句子(p2)。为什么一个用how,一个用what呢?
How do you think senior high school will be different from junior high school?——本句用 how,它是作状语的,指 be different 的程度,虽然翻译成汉语也可以是:你觉得高中和初中会有什么不同?其实是指“不同的程度如何”。
What do you think the principal will talk about in his speech?——本句用what,它是作宾语的,作介词 about 的宾语。句意:你认为校长会在演讲中说些什么?
