Ⅰ. seem “看來、似乎”既可作連系動(dòng)詞，以可做不及物動(dòng)詞，后接：形容詞、名詞、介詞短語或不定式。 如：
① Mother seemed to know that. 母親好像知道那件事。
② Bill doesn’t seem to a understand. 比爾似乎不太理解。= Bill seems not to understand.(這更正式)
Ⅱ. 常用搭配：
① It seems (that)好像、看來、似乎，如：
1. It seems to me that her accident is all your fault! 在我看來她出事都是你的錯(cuò)。
2. But it seemed that it wasn’t the only letter. 但是好像這不是的一封信。

1. It seems as though Ken will win the rice.看來賽跑Ken好像要贏。
2. It seems (as if ) it is going to rain. 天好像要下雨了。

① He looks / seems a nice man.他看上去是個(gè)好人。
② You look / seem tired. Let’s have a rest. 看來你累了，我們休息一會(huì)兒。
