UNIT 3 Back to the past表语从句[观察例句]1．The question is when he can arrive at the hotel.2．The book is not what I need.3．That is why she failed to pass the exam.4．The trouble is that we have no money.5．The argument is whether it rains tomorrow.[归纳用法]一、概念：从句在整个主句中作表语，因此被称为表语从句。表语从句隶属于名词性从句。放在系动词之后，一般结构是“主语＋系动词＋表语从句”，可以接表语从句的连系动词有be，look，remain，seem等二、引导词：连词 that /whether/as if /as though/because连接代词what / who /whom/which/whose/whatever/whoever/whomever/whichever连接副词 when / where/ why /how1．由连词that，whether引导的表语从句。主句的主语常常是抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。The trouble is (that) he has lost his money.麻烦的事是他丢了钱。The question is whether we need more ice cream.问题是我们是否还需要更多的冰淇淋。The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。2．由连词because，as if，as though引导的表语从句。(区别于主语从句)It looked as if it was going to snow.看起来好像要下雪了。That's because we never thought of it.那是因为我们从未想过此事。It seems as if he didn't know the answer.好像他不知道答案。That's because he didn't understand me.那是因为他没有理解我。3．由连接代词who，whom，what，which，whose及whoever，whomever，whatever，whichever引导的表语从句。连接代词既保留原意，又在从句中担当句子成分。The question is which of us should go.问题是我们哪一个应该去。The problem was who could do the work.问题是谁能做这项工作。That's what we should do.那是我们应该做的。4．由连接副词when，where，why，how引导的表语从句。连接副词除在句中起连接作用外，还在从句中充当时间，地点，方式或原因状语，本身具有词义。That's why he got angry with me.那正是他对我生气的原因。Go and get your coat.It's where you left it.去把雨衣拿来。就在你原来放的地方。I had neither a raincoat nor an umbrella.That's why I got wet through.我既没伞也没雨衣。这是我淋湿的原因。That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的。That is what he is worried about.那就是他所担心的。[即学即练]——单句语法填空①The reason why she couldn't have come to the meeting was that she had not been invited.②The difficulty we now meet with is how we can persuade him to tell us the truth.③The village school is no longer what it used to be.④Tom overslept this morning and that is why he was late for online study today.⑤With wonderful views of mountains and beaches，Lovers Point Park is where many people get married.Ⅰ.单句语法填空1．The fact is that the novel coronavirus epidemic(新型冠状病毒疫情)has a great influence on our life.2．I have been sleeping all day because of the present epidemic.That's why I don't know the latest news today.3．Chongqing is where my grandpa and grandma were born and brought up.4．The problem is whether your brother would go there with me.5．I think that is how friendship begins.6．When everyone quieted down，the speaker began to talk，saying that this is exactly what was happening in our lives.7．Obeying the traffic rules is what all of us should pay attention to particularly.8．The trouble is that I am anxious to telephone Mr.Smith but I have lost his number.9．The most exciting moment was when I was given the first prize.10．It seems that we are the same age.Ⅱ.短文语法填空Danger is not 1.what you expect.But the truth is 2.that it often comes suddenly and unexpectedly.How can you get out of danger？The key is 3.whether you can face danger bravely.What you must remember is 4.that you must believe in 5.yourselves/yourself(you)．Just remember that you can defeat danger.Tell yourself you can turn into a superman when you are 6.in danger.That is 7.why I am going to tell you the stories about Mrs.Pam.It is reported 8.that her body was nearly run over by a car when she was trying to save her baby.She looks as if she 9.were(be) weak，but she lifted the car 10.to save(save) her baby.
