Pay attention to something about
the “if” conditional sentences.
(1)条件状语从句通常由连词if引导, 意为“如果、假如”,
主句不能用be going to表示将来, 而应该用shall、will。
e.g. If you leave now, you are never going to regret it. (错误)
If you leave now, you will never regret it. (正确)
(2). if还可以表示“是否”，相当于whether, 用于引导宾语从句。I don't know if he come tomorrow. If he comes, I will tell you.(前一个if表示“是否”，后一个if表示“如果”。)
(3) if引导的条件状语从句可以转换为：祈使句＋and＋另一个句子；如果if引导的条件状语从句是否定句，可转换为：祈使句＋or＋另一个句子。
If you work hard, you’ll pass the exam easily.
=Work hard, and you’ll pass the exam easily.
=Work hard, or you won’t pass the exam easily.
Presentation
Pay attention to something about
the “if” conditional sentences.
在阅读英文文章时, 我们有可能看到这样的句子：
If my father will give me permission, I shall spend a few
months abroad.
如果我父亲同意, 我将在国外待几个月。
If you will take the trouble to read his letter carefully,
you will see what he means.
如果你肯花一些时间来认真读他的信，你就会明白
他是什么意思了。
在if-分句中中用“will＋动词原形”并不单纯表示将来意义，
这里的will是个表示“意愿”的情态动词, 相当于be willing to
(愿意)。
Presentation
What did you find out
I think I’ll take the bus to the party. If you do, you’ll be late.
I think I’ll stay at home. If you do, you’ll be sorry.
What will happen if they have the party today If they have it today, half the class won’t come.
Should we ask people to bring food If we ask people to bring food, they’ll just bring potato chips and chocolate.
if引导的条件状语从句替代词do的用法。
条件状语从句中的do,是替代词，代替上文中的动词短语，为避免重复,条件状语从句常用助动词do(does/did)来替代上文所提到的动作。take the bus to the party, stay at home.上边两句可以写成：If you take the bus to the party, you’ll be late. If you stay at home, you’ll be sorry.

know; do 句意“我不知道明晚参加迈克的生日聚会的事怎么做？”
don’t 后跟动词原形；what to + 动词形式，复合不定式结构。
2. think 本句表达一客观事实，主语parents是复数形式，故用一般
现在时态。句意“我父母认为我应当为下周的英语考试而学习” 。
3. go; will be 本句是含 if 条件状语从句的主从复合句；应遵循主将
从现原则。句意“如果我去参加聚会，他们会很失望。”
4. tells; have 本句为 but 连接的并列句，后半句为一般现在时，故前半句也应是一般现在时，主语 Mike 是第三人称单数形式，故填 tells；don’t 后跟动词原形。
5. wear; will look 本句为含if条件状语从句的主从复合句，应循主将从现原则。句意“如果我穿牛仔，我看起来会很糟糕。”
7. walk; will take 本句为含if条件状语从句的主从复合句，应循主将从现原则。
句意“如果我步行去，将会花费我很多时间。”
take; will be 本句为含if条件状语从句的主从复合句，应循主将从现原则。
句意“如果我乘出租车去，又将会很贵。” 。
advice是不可数名词，不能说an advice, 而是a piece of advice，
“两个建议”，我们通常说two pieces of advice.
注意：piece要采用复数，advice不可数，但piece可数。
我们也可以说为some pieces of advice一些建议。

Unit 10 Section A Grammar focus-3c 学案 (知识精讲+分层作业)
【重点语法】
if 引导的条件状语从句------基本用法
一、定义：
If 意为“如果”，引导条件状语 从句，表示假如从句的动作发 生，主句的动作就(不)会发生。 If it doesn't rain, I will go to the cinema tomorrow.
二、位置：
从句位置灵活，可放在主句之 前，但要用逗号与主句隔开；也 可放在主句之后。 My mother will take me to the park if she is free. If my mother is free, she will take me to the park
三：时态：
若主句为下列情形之一，条件状 语从句要用一般现在时
(1) 当主句为一般将来时：If he comes, he will bring his violin.
(2) 当主句的谓语中含有 can, may, must 等情态动词时：If you lose weight, you must eat less meat.
(3) 当主句为祈使句时：If you are not strong enough, please don't take part in such an activity.
注：助记口诀 if 条件句不一般，三个要点记心间： 主将从现、主情从现、主祈从现。
If 引导的条件状语从句------句型转换
1. 借助“祈使句+and/or+句 子”来转换 (and 表顺承，or 表转折)
If you study hard, you will pass the exam easily. = Study hard, and you will pass the exam easily. = Study hard, or you won’t pass the exam.
2. 借助without或with来转换
If there is no water, fish will die. = Fish will die without water.
if 引导的条件状语从句------辨析
1. if 引导条件状语从句和宾语从句的区别
(1) if 引导条件状语从句，表示“如 果”，从句需要遵循主将从现的原则
If it doesn't rain, I will go to the cinema tomorrow.
(2) if 引导宾语从句，表示“是否”， 从句不必遵循主将从现的原则
I don't know if he will come tomorrow.
2. If 与其他常见连接词的辨析
(1) if 意为“如果” Difficulties are nothing if we are not afraid of them.
(2) unless 意为“除非；如果不” We’ll go there tomorrow unless it rains.
(3) until/ till 意为“直到…” not…until 意为“直到…才” We waited until he came back. She didn’t stop working until eleven o’ clock.
(4) although/ though 意为“尽管； 虽然” We were not tired though /although we had worked all day.
(5) since 意为“自从”或“既然” Great changes have taken place in China since 1978. Since everyone is here, let’s begin our meeting.
【重点句型】
1. Could you give me some advice please
advice意为“劝告；建议”是不可数名词，不能说an advice, 而应说a piece of advice。“两个（则）建议”，我们通常说two pieces of advice。注意piece要采用复数，advice不可数，但piece可数。我们也可以说some pieces of advice一些建议。
Can you give me some advice
你能给我一些建议吗？
（1）advice 与 suggestion 两者都可表示“建议”，其区别如下：
advice 不可数名词。表示“一条建议”用 a piece of advice
I asked my teacher for some advice/ a piece of advice.
suggestion可数名词，复数形式为suggestions。
I asked my teacher for some suggestions/ a suggestion.
（2）与advice 相关的一些词组：
give sb. some advice 给某人一些建议
ask sb. for advice 征求某人的意见
take/follow sb.’s advice 听从某人的意见
ask advice of 向……征求意见, 请教
by sb.′s advice 依某人劝告
on sb.′s advice 依某人劝告
follow sb.′s advice 接受某人意见
give advice 劝告, 忠告
【拓展】
（1）固定搭配：give sb some advice(on/about…)
=give advice to sb(on/about…)给某人提（关于……的）建议；take one’s advice 接受某人的劝告。
Let me give you a piece of advice.
（2）advise为动词，意为“忠告，建议”，常构成“advise sb to do sth”;同义词为suggest。
He advised me to stop smoking.
2.…they’ll be too lazy to cook. ……他们会太懒惰而不做饭。
too…to…意为“太……而不能……”，其中too为副词，后面接形容词或副词；to为不定式符号，后面接动词原形。该结构可以与“so…that…(如此……以至于……)”进行互换，其中so后面接形容词或副词，that后面接否定句。
Linda is too tired to walk.
=Linda is so tired that she can’t walk.
If I go to the party, they will be upset. 如果我去参加聚会，他们将会失望。
upset adj.难过的；失望的; 常用作表语形容词。
What’s the matter, Mike You look very upset!
【拓展】be upset about…意为“对……失望”，后面接名词或动名词形式。
Linda is upset about her friend’s words.
