seem可以+形容词：Everything seems easy
也可以seem to be：
The maths problem seems to be very difficult
He seems to be sick. 看样子他病了
seem可与形容词、名词、不定式（短语）、分词及介词短语搭配。
1. seem + 形容词。如：
She seems quite happy today. 今天她似乎很高兴。
2. seem + 名词。如：
That seems a good idea. 那似乎是个好主意。
3. seem + 不定式（短语）。如：
He seems to be thinking about something. 他似乎正在考虑某事。
The policeman seemed to have known the truth. 那个警察似乎早已知道事情的真相。
注意：（1）不定式是to be并以名词或形容词作表语时，to be通常可以省略。这样就变成1、2的用法。如：
She seems (to be) quite unhappy. 她看起来很不高兴。
He seems (to be) a fool. 他好像是个傻子。
（3）seem的否定式可在不定式前直接加not或借助do的相应否定形式来表达（放在seem前）。如：
They seemed not to know each other. 他们看起来好像互不认识。
She doesn’t seem to like the idea. 她似乎不太喜欢这个想法。
4. seem + 分词。如：
He seemed pleased at what I said. 听了我的话，他似乎很高兴。
The news seems exciting. 消息似乎很激动人心。
5. seem + 介词短语。如：
They seemed in high spirits. 他们似乎情绪高涨。
