（2）Desks are made by workers.
4. It seems to be an interesting book.
seem在此表示“看上去”，暗示有一定依据，这种判断往往接近事实。而look着重于由视觉得出的印象，在搭配上两者都可接形容词、名词（前面常有形容词修饰）、动词不定式to be、介词短语。如：
He looks／seems a nice man．他看上去是个好人。
You look/seem tired. Let's have a rest. 看来你很累了，我们休息一会吧。
The boy looked/seemed to be very ill. 那个男孩看上去病得很重。
但以下几种情况，只能用seem，不能用look：
l）后面接动词不定式to do时。The new teacher seemed to know all his students．新来的老师好象认识他所有的学生。
2）用于It seems the that…结构时。It seemed that he lost something．看来他丢了什么东西。
3）用于There seemed +不定式结构时。There seemed to be hundreds of people on the playground. 运动场上好象有好几百人。
