是look at him

look是不及物動(dòng)詞，后面帶不了賓語(yǔ)，但是它和介詞at構(gòu)成動(dòng)介動(dòng)詞詞組，at后面就可以帶賓語(yǔ)了，表示看的對(duì)象、目標(biāo)。至于look at后我為什么選him,是因?yàn)樗竺嬉氖琴e語(yǔ)，人稱代詞he是主格，作主語(yǔ)用的，不可作賓語(yǔ)，him是人稱代詞賓格，作賓語(yǔ)用的，所以選用look at him.

是him不是he.,因?yàn)閍t為介詞，后接賓格him，中文意思是，看他。

When Spinks entered they all turned to look at him.當(dāng)斯平克斯進(jìn)來(lái)的時(shí)候，他們都轉(zhuǎn)過(guò)來(lái)看著他。

Mari tilted her head back so that she could look at him.

瑪麗把頭向后仰了仰，以便能看著他。

因?yàn)閍t是介詞，后面要跟人稱代詞的的賓格形式him，形成介賓結(jié)構(gòu)，例如：

1.I didn't dare look at him.我不敢看他。

2.He was watching her fixedly, willing her to look at him.他凝視著她，希望她也看他。

3.To look at him you'd never think he was nearly fifty.看他的外表，誰(shuí)也想不到他年近五十了。
