allow的用法allow to do sth 和allow doing sth 有什么区别?谢谢了
这个问题可以从语态上来区别:to do只能当allow用在被动语态的时候才能用,也就是只能是这种形式:
sb be allowed to do sth
He was allowed to drink some wine.
而allow doing 这种用法allow只能用在主动语态中,即:
sb allow doing sth
They allow our taking photo here.
从意义上来分别:
to do 结构中do的发出者是句子的主语(he);
doing结构中do的发出者不是句子的主语,而是另有他人(we).
allow sb. to do sth.
allow doing sth.
sb. be allowed to do sth.
基本用法就这些。
allow sb. to do sth.
allow doing sth.
即后面跟某人时,用不定式作宾补,否则就用动名词作宾语。
先说一下allow的意思:作为及物动词时 vt. 1. 允许,准许Swimming is not allowed at this beach. 这片海滩禁止游泳。 She allowed us to smoke. 她允许我们抽烟。
2. 准...进;准...出He doesn't allow cats in the room. 他不允许猫进入房内。
