例如 be commited to doing sth
这里to是介词,那么为什么 he made a commitment to help the poor. 同根出来的commitment,为什么这句话就要用不定式呢?
be committed to doing sth. (网友漏掉了一个 t)
make a commitment to do sth.
以上两个词组,不一样的词性,不一样的结构,没有可比性。
be committed to doing sth.:
这是一个形容词短语,意为“致力于做某事”。to 是介词,表示“致力的方向”,后面接名词或名词概念的成分,包括动名词在内。这跟下列词组是一样的结构,请记忆:
be devoted to
be dedicated to
be used to
be accustomed to
be adapted to
be adjusted to
be addicted to
be opposed to
be restricted to
make a commitment to do sth.:
这里的 commitment 是名词,跟make 搭配,表示“承诺”,后面是动词不定式。类似于;
make a promise to do sth.
make an effort to do sth.
