【文章內(nèi)容簡介】 was a pity. 很遺憾你沒去聽報告。(that不可省)It was a pity (that) you didn’t go to the talk. 很遺憾你沒去聽報告。(that可省)高考題：It never occurred to me__C_you could succeed in persuading him to change his mind.(陜西高考)A．which B．what C．that D．If首先要理解句意.這句話的意思是說,我從來沒想到你能夠成功地說服他去改變,而不是我從來沒想到你能否成功地說服他改變.第二,It never occurred to me是用于對于某個已發(fā)生的事實表示驚訝、吃驚的句型,所以這里you could succeed in persuading him to change這個事實只能用that來引導；if是用于引導一個不確定性（uncertainty）的,這里不可以用.It39。s obvious to the students___B_____they should get well prepared for their future.(天津卷)A．a(chǎn)s B．that C．which D．Whether,看出it為形式主語,代替that they should get well prepared for their future,并且本句意思完整,故選D.____B____some people regard as a drawback is seen as a plug by many others.(2010北京)A．Whether B．What C．That D．How,看出it為形式主語,代替that they should get well prepared for their future,并且本句意思完整,故選D.It is uncertain____A____side effect the medicine will bring about，although about two thousand patients have taken it.(2010浙江)A．that B．how C．what D．Whetherwhether是“是否”的意思這里應該是選B,what.因為跟后面side effect 連起來,what side effect,一起表示“是什么副作用”整句話的意思是“雖然有兩千多個病人服用的這個藥,但是對于其帶來的具體的什么副作用還是不明確的.”根據(jù)意思來選擇,只能是Bthat,how,whether都不能表達這個意思.主語從句練習題 makes mistakes must correct them.A. What B. That C. Whoever D. Whatever這句話強調(diào)的是普遍性，所以用whoever——任何人，而不是特指誰2. It worried her a bit ___B_ her hair was turning grey.A. while B. that C. if D. for 解析：句意：她的頭發(fā)漸漸變得花白,、,多放在句子后部,用it作形式主語,此時,that也不能省略. and why he came here ____A____ yet.A. is not known B. are not known C. has not known D. have not known因為,首先,這是現(xiàn)在完成時,yet 是現(xiàn)在完成時的提示詞,但是也可以是一般現(xiàn)在時第二,When and why he came here 這個整個句子做主語,凡是句子做主語的,都是單數(shù),因此是IS第三,這是被動,他何時來為什么來,還尚未為人所知悉如果是現(xiàn)
