参考答案:
2 1 4 3
知识点1  What would you do if you had a million dollars? 如果你有一百万美元，你将做什么？
【讲解】if引导虚拟语气的条件状语从句，从句为非真实条件句。非真实条件句是指假设的条件与事实相反或不可能实现。当虚拟语气表示与现在事实相反时，从句用一般过去时，主句用“should/would/could/might＋动词原形”，因此此句中would do和won均为虚拟语气。如：
If I had time，I would go for a walk.假如我有时间，我就去散步。（事实上，我现在没时间，不能去散步。）
If I were invited, I would go to the dinner party.假如邀请我，我会去赴宴。（事实上，别人现在没有邀请我，所以我也不能去。）
If I won a million dollars in the lottery, I would put it in the bank.假如我抽奖中了一百万美元，我会把它们存在银行里。（事实上，我现在没有抽中一百万美元，所以我也不可能存一百万美元在银行里。）
【例1】单项选择
① If I were a bird, I______ in the blue sky.
A．will fly
B．shall fly
C．would fly
D．can fly
②If I______a wallet, I would give it to the police.
A．find
B．found
C．finding
D．find
【解答】根据题意，两个句子表达的都是一种假设的或不可能的情况，因此要用虚拟语气。①答案C，②答案B。
归纳延伸：
if引导条件状语从句分为真实条件句和非真实条件句。
（1）表示将来真实条件句时，谓语动词主要形式如下:
主句
从句
一般将来时
一般现在时
（2）表示现在及将来情况的虚拟条件句（表示纯属假设或实现的可能性不大的情况）；谓语动词的主要形式如下:
主句
从句
Would＋动词原形
过去式
如：Please tell him if he comes.如果他来了，请告诉他。
He will play football if it doesn’t snow.如果不下雪他将去踢足球。
If you hurried，you would catch the bus.你要是快点儿就会搭上车的。（可是你这样太慢了。）
I would certainly go if I had the time.要是有时间我一定去。（但我没有时间。）
1c  PAIRWORK
Pretend you are the peoplein the picture.Talk with your partner about what you would do ifyou won a million dollars.假装你们是图中的人，和你的同伴谈论如果你中了一百万美元的大奖，你会做什么。
2a  Why is Larry nervous? Listen and circlethe reasons.拉里为什么紧张？听
录音并圈出理由。
听力材料:
Girl 1: Where are you going, Larry?
Boy 1:To Tom’s party.
Girl 1:Lucky you! I’d love to go to that party!
Boy 1:Yeah, well, I’m a little nervous. I don’t know what to wear.
Girl 1:If I were you, I’d wear a shirt and tie.
Boy 1:What if everybody else is wearing jeans and T—shirts?
Girl 1:Oh, you shouldn’t worry about what other people are wearing.
Boy 1: And I don’t have a present. What if everyone brings a present?
Girl 1: If I were you, I’d take a small present a pen or something. Keep it in your pocket and if everyone has a present, you can give him yours. If not, you can keep it.
Boy 1:OK. But what if I don’t know anyone?
Girl 1 :If you don’t know anyone, you can talk to Tom. He’ll introduce you to people.
Boy 1:I guess I can do that.
Girl 1: Look! You’re sure to have fun.But if you’re still nervous，you can leave.
参考答案:
2 3 5
知识点2  He doesn’t know if he should bring a present.他不知道他是否应该带一个礼物。
【讲解】此处if表示“是否”的意思，相当于whether，引导宾语从句。should此处表示“应该”，不是用来表示虚拟语气。
I don’t know if I should go to the party.我不知道我是否应该去参加那个舞会。（if引导宾语从句）
He doesn’t know if we will arrive on time tomorrow morning.他不知道我们明天早上是否会准时到达。（if引导宾语从句）
They willlet me know if they change the plan.如果他们改变计划，他们会通知我的。（if引导条件状语从句）
If I have enough money next year，I will go to England.明年如果我有足够的钱，我打算去英国。（if引导条件状语从句）
【例2】选择能代替画线部分的选项。
①She wonder if she will pass the exam.
A．whether
B．when
C．how
D．in case
②I don’t know if he________（come）. If he ______（come）, pleasetell me.（用动词的正确形式填空）
警示
if 作“是否”讲，引导宾语从句，从句中可以用一般将来时或其他时态。if 作“如果”讲，引导条件状语从句，从句中用一般现在时代替一般将来时。
【解答】①从句使用will pass一般将来时，if是引导宾语从句，答案是A。②前者if是“是否”之意，引导宾语从句，答案为will come，后者if是“如果”之意，引导条件状语从句，答案为comes。
归纳延伸:
if用于不同复合句有不同的意义，在不同的复合句中，应仔细区分它的含义以及它所引导的从句所使用的不同时态。作宾语从句引导词时，主句如是一般现在时，从句常用一般将来时；作条件状语从句引导词时，从句常用一般现在时。
2b Listen again.Check（√）the four things Larry’ssister says to him.重新听录音，用（√）标出拉里的妹妹对他说的四件事。
参考答案:
1 2 4 5
知识点3  If I were you, I’d wear a shirt and tie.假如我是你，我将穿衬衣打领带。
【讲解】if引导的条件状语从句表示与现在事实相反的虚拟语气时，be动词只能用were，而不能用was。如：
If I were you，I should study very hard.假如我是你的话，我就努力学习。
If I were you，I would do more practice after class.假若我是你的话，我课后就多做练习。
If he were here，he would not agree with you.假如他在这里的话，他不会同意你的。
【例3】单项选择
If I______you, I______ the job.
A．am, will take
B．was, would take
C．were, would take
D．will buy, will have
【解答】题意为“如果我是你，我将接受这份工作”，这是运用if引导条件状语从句表示假设，应用虚拟语气，从句中be动词were，主句谓语动词为would take，答案是C。
2c  PAIRWORK
Student A，you are Larry.Student B，you are Larry’s sister.Student A，talk about your worries.Student B，give advice.学生A，假设你是拉里，学生B，假设你是拉里的妹妹，请学生A谈一谈你的忧虑，请学生B提出建议。
知识点4  I don’t have a present.What if everyone else brings a present? 我没有礼物，假如别人带了礼物怎么办？
【讲解】What if...? 表示“如果……，怎么办？”“要是……又怎样？”，相当于What would happen if...? 常用于口语中。如：
Whatifit’s true? 万一那事是真的怎么办呢？
What if it rains when we can’t get under shelter? 假如下起雨来，我们又没处避雨怎么办？
【例4】同义句转换。
①What if aliens should come to the earth?
What______ ______if aliens should come to the earth?
②What if I don’t know anyone?
What______I______if I don’t know anyone?
【解答】①would happen②shall，do

知识点5Well，dogs can be a lot of trouble.噢，狗可能带来很多麻烦。
【讲解】trouble此处作名词，表示“麻烦（事）”，还可表“困难，苦恼”。
trouble还可作动词，“使忧虑，麻烦某人做某事，打扰”等意思。
get into trouble陷入困境，遇到麻烦
get sb.into trouble使某人陷入困境
get out of trouble摆脱困境
What’s the trouble? 相当于What’s the matter? 或What’s wrong? 如：

I hope I’ve not given you any trouble.我希望没有给你增添麻烦。
I had no trouble finding his office.我毫不费力就找到了他的办公室。

D．will trouble

【解答】①题意为“不要自找麻烦”，主句中第一个trouble是动词，第二个trouble 是名词，until引导的从句中第一个trouble是名词，第二个trouble是动词，答案是B。②题the trouble相当于the matter，答案是A。
