高中英语语法：It的完整用法精讲 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。 10）It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 11）It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 it也常用来表示一般的笼统的情况。如： 12）It's awful—I've got so much work I don't know where to start. 糟透了——我有这么多工作要做我不知从何开始。 13）How is it going with you? 你近况如何？ 14）Take it easy. 不要紧张。 it也常用于下列结构： 15）It looks as if the college is very small. 看起来这个学院很小。 16）It seems as though our plan will be perfect. 似乎我们的计划很完善。 17）It's my turn. 该轮到我了。 it也常用于某些习惯用语中作宾语，各该习惯用语有具体意义，但it并无具体意义。如：cab it 乘车catch it 受责，受罚come it 尽自己分内come it strong 做得过分walk it 步行make it 办成take it out of somebody 拿某人出气 4. 先行词it. it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用，先行词不重读。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语

高考英语知识点介词in的用法总结 来源：互联网 英语是一门很讲究知识积累的科目，没有扎实的基础就很难考得高分。小编为您搜集整理了2013年高考英语相关知识点，希望同学们能够认真看一看。 小编寄语：介词 in 在英语中很常见，但是用法却很复杂。下面小编为大家提供介词 in 的用法总结，供大家参考。 1. 表示时间，表示“在……后”，注意它与after的区别：虽然两者均可与一段时间连用，表示多久之后，但in 以现在时间为起点，表示从现在起多久以后，通常用于将来时态或含有将来意味的句子；而 after 则以过去或将来时间为起点，表示从那以后。如：I’ll come back in five minutes. 我5分钟后就回来。（以现在时间为起点） He came back after five minutes. 5分钟后他就回来了。（以过去时间为起点）但是，若after后接的不是一“段”时间，而是一“点”时间，则完全可以现在时间为起点。如： I’ll come back after five o’clock. 我5点钟以后回来。 不过，在现代英语中，以上规则有时被打破。如： I may come after a day or two. 我可能过一两天会来。 Wang Bing is leaving the USA after two days. 两天后王兵要离开美国。 2. 类似in three days 这样的短语，有时含义不易确定，因为它既可表示“3天内”，也可表示“3天后”，大致可以这样区分：若与延续性动词连用，则表示“3天内”，若与非延续性动词连用，则表示“3天后”。如： He learnt English in three weeks. 他在3周内学会了英语。 The train will arrive in a few minutes. 火车过几分钟就到。 但语言的实际并不完全是这样，有时需视具体的上下文或语境来确定。如： We should be able to complete the work in five days. 我们应该能在5天内完成这工作。

高考英语语法知识之It 的用法总结 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，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 they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was 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 ... 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。 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 ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ... 该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9.

精品文档 精品文档英语连词for的用法总结 1、for在英语学习中，我们经常用到，for做连词时引导原因状语从句，主要表示理由，用于引导的分句对前面的话进行解释，起到补充说明的意思，常用逗号把它和前面的分句分开。例如： Humanity had better hope so, anyway，for the truth will soon out for the entire species.不管怎样，人类最好希望如此，因为这种真理将对整个人类显示出来。He must be in now, for the light in his room is on. 他现在一定在家，因为他房间的灯是亮着的。（灯亮其实并不能说明人一定在家）。注意：for表示原因时的四个“不能”for引导的从句不能位于它所解释的动词之前、for引导的从句不能位于not, but或任何连词之后、for引导的从句不能用于回答问题、for引导的从句不能单单用来复述已讲过的话，而必须包括新的内容。for 引导的从句不能直接说明某一特定动作发生的原因，而只能提供一些起帮助解释作用的附加说明。2、for的用法很广泛，for除了用作连词表示原因、理由之外，它还可以用作介词等： 1）表示“当作、作为”。如： I like some bread and milk for breakfast. 我喜欢把面包和牛奶作为早餐。What will we have for supper? 我们晚餐吃什么？ 2）表示动作的对象或接受者，意为“给……”、“对…… （而言）”。如： Let me pick it up for you. 让我为你捡起来。 Watching TV too much is bad for your health. 看电视太多有害于你的健康。3）表示时间、距离，意为“计、达”。如： I usually do the running for an hour in the morning. 我早晨通常跑步一小时。We will stay there for two days. 我们将在那里逗留两天。 4）表示去向、目的，意为“向、往、取、买”等。如： Let's go for a walk. 我们出去散步吧。 I came here for my schoolbag.我来这儿取书包。 I paid twenty yuan for the dictionary. 我花了20元买这本词典。 5）表示所属关系或用途，意为“为、适于……的”。如： It's time for school. 到上学的时间了。 Here is a letter for you. 这儿有你的一封信。 6）表示“支持、赞成”。如： Are you for this plan or against it? 你是支持还是反对这个计划？
