重难点精讲
考点1 seem的用法
seem作系动词，意为“像是, 似乎”，后接形容词作表语。如：
Everything seems easy. 一切似乎很容易。
seem 还用于句型：It seems (or) seemed (that)...。如：
The little boy seems to know everything.＝It seems that the little boy knows everything. 这个小男孩似乎什么都懂。
It seems that no one knows what happened. 看来没有人知道发生了什么事。
seem后还可跟不定式。如：
The teacher seems to be very angry. 这位老师好像很生气。
seem还可用于“It seems as if 加从句”的结构中。如：
It seems as if it is going to rain. 天看起来要下雨了。
seem用于否定句，既可以否定seem，也可以否定不定式。如：
My sister doesn't seem to like hamburgers.
=My sister seems not to like hamburgers.
我妹妹似乎不喜欢汉堡包。
