seem常与多种词性搭配使用，具体如下：

1. 与不定式或短语搭配，如"It seems to be raining."或"It seems that he is coming."

2. 与形容词搭配，如"It seems good."或"It seems interesting."

3. 与分词搭配，如"It seems walking in the park is good for health."

4. 与名词搭配，如"It seems success lies in hard work."

5. 与介词短语搭配，如"It seems in the garden that flowers are blooming."

seem也常用于由as if/though引导的从句中，表示对情况的推测或感觉。例如：

a) It seems as if it is going to rain.

b) It seems as though our plan'll be perfect.

c) It seems as if he knew nothing about that.

d) It seems as if it was/were spring already.

在使用这种句式时，若从句所描述的情况有可能实现，则谓语使用陈述语气，如例子a和b；若实现可能性较小或根本不可能实现，则谓语使用虚拟语气，如例子c和d。
