* ㈠ 1.it作人称代词 1.1.it的最基本用法是作人称代词,主要指刚提到的事物,以避免重复: Ningbo is a beautiful city, isn’t it? 1.2.也可以指动物或婴儿(未知性别的婴儿或孩子): Is this your dog?No, it isn’t. 1.3.也可指抽象事物: It was a great surprise to me when he did a thing like that. 2.非人称代词it it有时并不指具体的东西,而泛指天气、时间、环境等,称为非人称的it: 2.1.指天气: It is a lovely day, isn’t it?It is a bit windy. 2.2.指时间:It was nearly midnight when she came back.2.3.指环境:It was very quiet in the café.2.4.指距离: It is half an hour’s walk to the city centre. 3.it的其他用法 3.1.表示谁在做某事的句子:Who is it? ---It’s me.Her face lighted when she saw who it was. 3.2.用来泛泛的指某件事:So you are going to be married this time?When is it?It doesn’t matter.It is a shame, isn’t it? ㈡.it的重要句型1. It is + 被强调部分 + that ... 该句型是强调句型。将被强调的部分放在前面,其它部分置于that之后,被强调部分可以是主语,宾语,表语或状语,强调的主语如果是人,that可以由who换用。如果把这种句型结构划掉后,应该是一个完整无缺的句子;这也是判断强调句型与其它从句的方法。 It was about 600 years ago that the first clock with a face and an hour hand was made. It was they that (who ) cleaned the classroom yesterday. It was in the street that I met her father. 2. It is not until + 被强调部分 + that ... 该句型也是强调句型。主要用于强凋时间状语,译成汉语"直到...才...",可以说是 not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3. It is clear ( obvious, true, possible, certain....) that ..... 该句型中it 是形式主语,真正的主语是that 引导的主语从句,常译为"清楚(显然,真的,肯定...)" 是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree. = That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 该句型和上一个同属一个句型;由于主句中的形容词不同,that 后的从句中要用虚拟语气(should + 动词原形),should 可以省去,建议记住该句型中的形容词。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型
