表示动作正在进行，而不带 to 的不定式则一般表示动作已经完成。如： I saw him putting his hand into his pocket. (动作正在进行) I saw him put his hand into his pocket. (动作已经完成) It seems that 用法
此句型实质上是“主＋系＋表”结构。其中it是人称代词，并无实意，指的是某种情况，seems为系动词，that / as if 引导表语从句。 一、It seems that „表示“看起来„„”。
强调根据一定的事实所得出的一种接近于实际情况的判断，可以说表示事实。（可以转换成“名词或代词 ＋ seem ＋动词不定式”句型，其意不变，如果动词不定式为to be ＋ 形容词时，to be往往省略。）
It seems that it is more difficult for women to get to the top of the company. 妇女似乎更难提升到公司的最高职位。
It seems that no one knows what has happened in the park. (No one seems to know what has happened in the park.) 似乎没有人知道在公园里发生了什么事。
It seems to me that he has known everything. (He seems to have known everything) 在我看来他似乎什么事都知道了。

It seems that she is happy. 她似乎很高兴。
It seems that he likes his new job. 他看起来很喜欢他的新工作。 It seems that they don't like the idea. 他们似乎不喜欢这个主意。 It seems that he is lying.看来他在撒谎。
二、It seems as if ...也表示“看起来„„，似乎„„”。
使用该句型表示可能：若从句表示的是很可能实现的事情，从句谓语用陈述语气；若从句表示的是与事实相反的假设或实现的可能性很小的事情时，则从句谓语要用虚拟语气。
1、从句的谓语动词常用虚拟语气来表示所设想的事情不真实或不可能发生/存在。
It seems as if she had read this novel.看来她好像看过这本小说。 It seems as if it were autumn. 现在仿佛是秋天似的。 It seems as if it were spring already. 似乎春天已经来了。 It seems as if he knew everything. 好像他什么都知道似的。 It seems as if she had been to England. 好像她到过英国似的。

It seems as if he were in a dream.看来他像是在做梦。
It seemed as if the good man were trying to teach us all he knew at this last lesson.这个好心人仿佛要在最后这一堂课上把他的全部知识教给我们。
2、如果可能性很大则用陈述语气，或者句中的情况可能发生或可能被设想为真实，则仍然用陈述语气。
It seems as if our team is going to win.看来我们队要胜了。 It seems as if he has learned by heart a speech written by someone else.看来他像是背了一篇由别人写的演讲稿。
It seems as if he has been at the scene of the crime似乎他好像在犯罪现场。

It seems that it is going to rain. 仿佛天要下雨。 It seems as if Ken will win the race. 看上去肯好像能赢。 It seems as if our team is going to win． 看来我们队要胜了。 3、as if还可用于其它动词之后或省略句中。
（as if引导的从句是“主语＋系动词”结构，可省略主语和系动词，只剩下名词、不定式、形容词（短语）、介词短语或分词。）
