有write sb to do I will write you soon to let you know more abou the show.不是write to sb.为什么这里没有to?

问题描述:

有write sb to do
I will write you soon to let you know more abou the show.
不是write to sb.
为什么这里没有to?

to let you know more abou the show 这是不定式的目的状语
write to sb 中间的to介词可以省略

write是一个可以接双宾语的动词.给你写一封信可以有两种说法:
i will write a letter to you.或者i will write you a letter.
你给的句子用的就是第二种,只不过没有加上直接宾语.
而to let you know more about the show并不是与write sb.连在一起构成短语,而是一个不定式做目的状语.
