不定式做宾语
有些动词常用动词不定式作宾语

我们约定在这里见面，但是到现在她都还没露面。
He offered to help us.他提出要帮助我们。
Mary begged to go with us.玛丽恳求同我们一块去。
常用动词不定式作宾语的有如下动词：
Agree, ask, attempt, begin, care, choose, continue, Decide, desire, determine, expect, forget, hate, hope, Intend, learn, like, love, manage, mean, offer, prefer, Pretend, promise, refuse, start, try, undertake, want, and wish
主语 + 谓语动词 + it + 形容词/名词/代词 + 不定式
解释：这里的"it"是形式宾语，"形容词/名词/代词"是宾补，"不定式"是真实宾语。这里需要用"it"作为形式宾语的原因是不定式短语太长，而挪到后面去，以保持句子的平衡。
We think it wrong to tell a lie.我们认为说谎是不对的。
I felt it useless for us to say anything further.我觉得我们再说下去也没有用。
