Unit4 Grammar
1.作人称代词和非人称代词的用法
在正确运用it的基础用法上,重点掌握:作形式主语作形式宾语并能在所给题干提示的语境和逻辑关系中灵活运用.
It 是一个特殊的代词，它有两重意义。一是作为代词，另一个是当作连接词(引导词)。
它可以用来代替事物和前面提到过的事,也可以用来表示时间,天气等.还可以用作先行代词及引导次.
具体用法作代词:1. 指代事物或前面提到过的事物:
What is this ?It is a picture.
It is a lvely and cute panda, isn’t it?Yeah. I wn’t frget it!
Hw is the weather?It is rainy.
What's the time? It is twenty past tw.
Hw far is it frm yur hme t yur schl?
It is nly five minutes’ walk.
4. 表示情况或代替this, that:

it作形式主语。英语中不定式、动名词、主语从句在作主语时主语往往显得很长，使整个句子看上去有点 头重脚轻，这样就借助“it”来作形式上的主语，而把真正的主语移到句子后边去，使全句看上去平稳一些。 “it”没有实际的意义。 It + be+ adj. // n. +t d It is easy t climb the hill.It is his duty t slve the prblem.
2) It + be + n use / gd + gerund (动名词)做某事是没用的。It is n using arguing with him.做某事是没好处的。I t is n gd ging there.
2.作形式宾语。这种情况通常只用于能带以名词或形容词作宾语补语的动词后面。常用于下列句型:feel; think; make; find…+it adj. // n. +t d …E.g. I fund it nt easy t get n with Jim. We all think it imprtant t learn English well.
It 句型:1.It + is/was/ has been +一段时间 + since+过去时自从我上次见到他已经有两年了。 It is tw years since I last saw him.我离开学校五年了。 It has been three years since I left the schl.
It 句型:2. It takes/tk sb sme time t d sth 花费某人多少时间做某事他们花了3年时间盖这栋大楼。 It tk them 3 years t build the skyscraper.我用了三天读完这本书。 it tk me three days t finish reading the bk.
3. It + seems / appears that好像。。。 好像不久有选举。 It seems that there will be an electin sn. 看来要下雨了。 It appears that it’s ging t rain.

1）It + be + fr sb. + t d sth.做某事对于某人来说怎么样 如果不定式的逻辑主语是由fr引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易度等情况的形容词，常见的有：imprtant, safe, cmmn, difficult等。 做这项工作对我来说很难。 It’s difficult fr me t d this wrk.
5. 2） It + be + f sb. + t d sth.某人做某事某人怎么样 如果不定式的逻辑主语是由f引起，主句中的形容词必须是能表示主语特征的形容词。常见的有：bad; brave; careless; clever; flish 等，这个句型可以改写为：sb. + be + adj. + t d. 你这么说太好了。 It’s kind f yu t say s.=Yu are kind t say s.
