2019-2020年高中英語 Unit4 Astronomy Grammar 新人教必修3課前預(yù)習(xí) 一.語法知識：主語從句：做主語用的名詞性從句，因其在復(fù)合句中做主語，又稱主語從句，引導(dǎo)主語從句的有從屬連詞that, whether， 連接代詞who, what, which， 連接副詞when, where, how, why等。1.連接詞：1）從屬連詞：that， whether等.that 引導(dǎo)主語從句只起引導(dǎo)作用，本身無實際意義，在主語從句中不充當(dāng)任何成分，但不能省略。That she left him cut him to the heart.That he will e is certain由whether及其他連詞引導(dǎo)的主語從句放在句首，句后都可。 Whether it will please them is not easy to say.Whether shes ing or not doesnt matter too much.2)連接代詞who ，what ，which, whatever, whichever, whoever What seems easy to some people seems difficult to others.Which side will win is not clear.3)連接副詞when，where， how， why等。Why he did it remains a mystery.When they will start is not known yet.How he became a great scientist is known to us all.2.位置：主語從句可以前置，也可以后置。用it做形式主語，而把主語從句放在句末，常用下面幾種句型。1）It + be + 表語 +主語從句表語：（名詞,形容詞,過去分詞）It is a pity that we cant go.It is no surprise that our team should have won the game.It is an honour that I was invited to attend the meeting.It is certain that she will do well in her exam.It is true that I told her everything.It is said that Mr. Green has arrived in Beijing.It is reported that China has sent another manmade earth satellite into orbit.2）It+不及物動詞或短語+主語從句It seemed (happened, doesnt matter, has turned out) that It happens that they were absent.It seems that Alice is not ing to the party at all.It doesnt matter whether she will e or not.It makes no difference where we shall have the meeting.3) It +及物動詞（被動語態(tài)）+主語從句It has been decided that the exhibition will not open on Sundays.注意:1）主語從句在句首時，必須由連接詞引導(dǎo)，不能省略這些連接詞；但是如果用it做形式主語，而把主語從句放在句末時，從屬連詞that可以省略。誤：They should like each other is natural.正：That they should like each other is natural.正：It is natural that they should like each other.2)如果主語從句放在句首，不能用if引導(dǎo)，但是如果用it 做形式主語，而把主語從句放在句末時，也可以用if引導(dǎo).誤：If Mary really heard him is really doubtful.正：It was doubtful if Mary really heard him.從文章中找出以下主語從句并試著分析：1).What it was to bee was a mystery until the dust began to slowly bine into a ball moving around the sun.2). because it was not clear whether the solid shape was to last or not.3).What scientists think is that the earth was different because of 4).Whether life will continue on the earth for millions of years to e will depend on 實戰(zhàn)演練一用正確的連接詞完成下列句子：1._ the universe is like has attracted Stephen Hawking all his life. 2._ is clear and simple about the universe has always seemed too difficult for us to answer.3._ the universe exists the way it does is a major question to all those who have looked at stars like Hawking.4._ has developed over two thousand years of observation has to be greatly revised.5._ in the universe we live is not the centre, but one of the nine planets orbiting the sun, which is just one of millions of stars in our own Milky Way galaxy.6._ we understand the universe is the time when we human beings will have answered all the questions.7._ we can have a plete picture of the universe depends on learning to understand what we see.8._ Hawking wants to tell us in this text is that we should study the universe, and understand it.二單項填空：1.I have always been honest and straightforward, and it doesnt matter _that Im talking to.A. who is it B. who it is C. it is who D. it is whom 2.
