SAT語法解析之it用法.

　　SAT語法令很多同學(xué)都頭疼，大家需要了解SAT語法考點的內(nèi)容有助于大家分清重點與次重點。下面小編就來給大家介紹一下SAT語法真題中有關(guān)于it的用法。

　　一、考查 it 用作形式主語的用法當(dāng)不定式、動名詞、從句等用作主語時，為避免頭重腳輕，通常在句首使用形式主語it，而把真正的主語放在句子末尾。如：It&aposs no good sitting up too late. 熬夜沒有好處。

　　It is quite clear that he has read the book. 很顯然，他讀過這本書。

　　It doesn&apost matter what he says. 他說什么沒關(guān)系。

　　【特別提醒】注意it用作形式主語的三類特殊句式：1.用作動詞look, seem, appear, happen, occur, follow等的主語(后接that從句或as if從句)。如：It seems that he knows everything. 他好像什么都知道。

　　It (so) happened that I had no money with me. 碰巧我沒帶錢。

　　2.當(dāng)系表結(jié)構(gòu)后接有if 或when引出的狀語從句時，通常在系表結(jié)構(gòu)前使用形式主語表示說話人對某情況的看法。如：It was a great surprise to me when he did a thing like that. 他這樣做使我很吃驚。

　　It would be a tragedy if anything went wrong. 如果出了什么事就是一個悲劇。

　　3.用于if it were not for… / if it hadn&apost been for…(若不是因為)。如：If it hadn&apost been for the freezing wind they could have reached the injured man in time. 要不是有刺骨的寒風(fēng)，他們就及時趕到傷員身邊了。

　　二、考查 it 用作形式賓語的用法當(dāng)不定式、動名詞、從句等用作賓語且其后跟有賓語補足語時，就應(yīng)在賓語補足語前使用形式賓語，而將真正的賓語移至句末：We found it difficult to persuade her. 我們發(fā)現(xiàn)很難說服她。

　　He makes it a rule to get up bore dawn. 他習(xí)慣于天亮前起床。

　　I think it very strange that he goes out walking almost every night. 我認(rèn)為他幾乎每晚都出去散步是很奇怪的。

　　【特別提醒】注意it用作形式賓語的三類特殊句式：1. 動詞+it+if / when從句當(dāng)enjoy, like, dislike, love, hate, prer, appreciate等動詞后需要接一個if或when引導(dǎo)的從句時，此時必須要先在動詞后接it作形式賓語。如：She won&apost like it if you arrive late. 她不喜歡你遲到。

　　He hates it when people use his bike. 他討厭別人用他的自行車。

　　I&aposd prer it if I didn&apost have to do so much work. 要是我不必做那么多工作，那就太好了。

　　I would appreciate it very much if you would help me with it. 如果你能幫助我做這事，我會十分感激。

　　2. 動詞+介詞+it+that從句能用于此句型的主要有三個動詞，即depend on, answer for, see to.如：You may depend on it that he will turn up in time. 你可以相信他會及時趕到的。

　　I can&apost answer for it that the boy is honest. 我不能保證這個男孩是誠實的。

　　I&aposll see to it that all these letters will be sent to the post bore twelve. 我將注意讓所有的信件在12點以前送到郵局。
