It is said (reported, learned…) that…‎ 该句型中的it 仍是形式主语，真正的主语是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.‎ It is reported that another earth satellite has been put into orbit.‎ ‎6.

It is the first (second, …)time that…‎ 该句型应和上一个句型区别开来。该句型中不用虚拟语气，而用完成时态。至于用哪种完成时态，由主句的谓语动词的时态来决定。如果是一般现在时，从句用现在完成时态；如果是一般过去时，从句则用过去完成时态。该结构中that可以省去；it有时用this替换，常译为“是第一（二,…）次…”。‎ ‎10. It is …since…‎ 该句型主要用作处理瞬间动词的完成时，要和表示一段时间的时间状语连用。主句中是时间作表语，其时态是现在时和完成时，引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。‎ It is (has been) 5 years since his father died.‎ It is almost five years ___we saw each other last time.

It happens (seems, looks, appears) that…‎ 该句型中的it 是形式主语，that 引导的是主语从句，主句中的happen, seem等词是不及物动词。‎ It happened (so happened) that he met his teacher in the street.  (碰巧……)‎ It seems that he will be back in a few days.  (看来……)‎ The Foreign Minister said, “___our hope that the two sides will work towards peace.” (2004北京)                          ‎ A. This is   B. There is   C. That is   D. It is (D) ‎ ‎14.

A. it, it                    B. what, what C. it, what               D. what, it 【陷阱】很容易误选B，认为两空均考查形式主语。 【分析】最佳答案是D，第一空填形式主语，真正的主语是其后的不定式 to play with fire。第二空填 what，what is difficult 是主语从句，注意 what is difficult 后的谓语动词 is。请做以下类似试题： (1) I know ______ is important to know my own limitations, but _______ is difficult is to help others to know their own limitations. A. it, it                    B. what, what C. it, what               D. what, it (2) Yes, ______ is difficult to find a job nowadays, but _____ is more difficult is try to find such a job with a high salary but little things to do.

A. that                    B. those C. it                        D. them 【陷阱】几个干扰项均有可能误选。 【分析】最佳答案是C，因为在通常情况下，like 是及物动词，其后应有宾语(句中 it 即为其宾语)。句中的 when 从句不是宾语从句，而是时间状语从句，其中的 when 的意思是“当……的时候”。其实，也有的词典将 I don’t like it when (if) … 作为一个句型来处理。能这样用的动词不多，主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示喜好的动词。 She won’t like it if you arrive late. 她不喜欢你迟到。 He hates it when people use his bike. 他讨厌别人用他的自行车。 请做以下类似试题(答案均选 it)： (1) I hate _______ if people say such things in public.

A. he                      B. that C. she                     D. it 【陷阱】容易误选A或C。 【分析】最佳答案是D。it 用以指身份不明的人。若指身份明确的人，则不宜用it。比较： (1) Mr Smith is at the door. _______ wants to see you. (2) Someone is at the door. ________ must be Mr Smith. A. He                      B. It C. This                    D. That 第(1)题选A，因为来者身份明确；第(2)选B，因为来者身份不明确。 4. “Excuse me, I want to have my watch fixed, but I can’t find a repair shop.” “I know ________ nearby. Come on, I’ll show you.” A. one                     B. it C. some                   D. that 【陷阱】容易误选B。 【分析】最佳答案是A。it 和 one 的区别可简单地概括为：it = the + 名词，one = a + 名词。如： I haven’t got any pens, and I want to borrow one. 我没有钢笔，我想借一支。(one = a pen) I have two pens, and I can lend one to you. 我有两本支钢笔，我可以借一支。(one = a pen) I have a pen, and I can lend it to you. 我有一本钢笔，我可以把它借给你。(it = the pen) 在上面一题中，one 相当于 one 相当于 a repair shop。请做下面一题（答案选A）： There is only one English-Chinese dictionary in that book-shop.

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。例如：‎ ‎ It is clear that he is wrong. （这是很清楚的事，他错了。）‎ ‎2． It is v-ed that…=sb/sth is to do It is said (reported/ learned/believed/thought/known/told/hoped.....) 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．．．）”。例如： ‎ It is reported that another earth satellite has been put into orbit. （据报道，另一个地球卫星已经进入轨道。）‎ ‎④ It is + noun +从句 ‎ It is a pity (a shame /an honor /a good thing/a fact /a surprise/...) 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。例如：‎ It is a pity that he is ill. （他生病了，真遗憾！）‎ ‎5）it作形式宾语 当复合宾语中的宾语是不定式、动名词宾语从句时，往往把宾语放在它的补足语后面，而用it 作形式宾语，放在宾语补足语之前。‎ 该句型中的it 作形式宾语，常用的动词有think, believe, make, find, consider, feel等。 例如： ‎ I find it necessary to read more. （我发现多读很有必要。）‎ ‎6）用于强调句型 It is/was + 被强调部分 + that/who ... 例如： ‎ It is Tom that answered the question. （是汤姆回答地这个问题。）‎ It is not until + 被强调部分 + that ... 例如： ‎ It is not until the professor come that they begin the test. ‎ ‎（直到这位教授来了,他们才开始测试。） ‎ It的用法专项练习习题精选 ‎2011-10-07 00:45 来源：互联网作者：佚名 [打印] [评论]‎ ‎　　1.
