if引导一个条件状语从句
当主句是一般将来时时, if引导的从句必须用
现在时来表示将来可能发生的动作或存在的状态。
Grammar Focus: if 条件状语从句
在英语里, 当句子的主句为将来时态时, 它所引导的
时间状语从句和条件状语从句都使用一般现在时来
表示将来时间, 这在英语里被称为“主将从现”。
主句的将来时态并不仅限于我们这一课里所学习到
的will＋动词原形构成的一般将来时, 还包括be
going to＋动词原形、be doing所表示的一般将来时以及我们以后会学到的其它的将来时态。例如:
What is he going to do when he grows up
他长大了想干什么？
We are leaving for Xiamen tomorrow if it doesn’t rain.
如果明天不下雨, 我们就去厦门。
We will buy that microwave next week if its price
keeps going down.
如果价格持续下降, 下个礼拜我们就买那台微波炉。
If +…, I’ll / you’ll +…

get up late, you’ll be late.
eat too much, you’ll be fat.

If 是引导词，意为 “如果，假设”，由if引导的条件状语从句，表示主句动作发生所需要的条件。
If it rains tomorrow, we’ll stay at home.
如果明天下雨，我们就呆在家里。
I’ll go to see you if I have time.
如果我有时间，我就去看你。
If 引导的条件状语从句位置灵活，可直接放在主句后面，也可以放在句首。放在句首时，从句和主句用逗号隔开。
如果有时间，我就去看你。
If I have time,
I will go to see you.
I will go to see you
If I have time.
If she doesn’t come, she will be sorry.
If you don’t hurry up, you’ll miss the train.

这里if所引导的是真实条件句(real conditional), 即所假设的条件有可能成为现实, 表达假定所假设的条件实现时会出现的情况或会采取的行为。有时, 我们可以使用并列结构的祈使句来表达这种类型的条件句。
e.g. If you set your alarm clock, you won’t oversleep.
如果你上闹钟, 你就不会睡过头了。
Set your alarm clock, and you won’t oversleep.
If you give him an inch, he will take a mile.
他会得寸进尺。
Give him an inch, and he will take a mile.
If you don’t give him some food, he will starve.
如果你不给他一点吃的, 他就会饿死。
Give him some food, or/else he will starve.
Have a good rest if you are tired.
Don’t wait for me if I am late.

Summary
(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 “如果”, 引导条件状语从句, 主句用一般将来时，
从句则用一般现在时，如：　If it rains tomorrow, I shan’t climb the hills.
注意：1.
注意2:
宾语从句中的 if 与条件状语从句if的区别。
宾语从句中的if “是否”相当于whether, 引导
宾语从句, 时态需根据语境确定。
I don't know if it will rain tomorrow. 我不知道明天是否会下雨。
我把知道他明天是否回来，如果他来了，我将告诉你
I don't know if he will come tomorrow. If he comes,I'll tell you .
1.如果你不赶快走, 你就会迟到。
2 .如果你爱你的父母, 你应当帮他们做做家务。
3. 如果你更友善一些, 你会教上很多好朋友。
Exercise
If you don’t go soon, you’ll be late.
You should help do the housework if you love your parents.
You will make lots of friends if you are more
friendly.
4.如果你带外校的朋友来, 老师会让他们离开。
5. 如果你不完成作业, 妈妈不会让你玩电游。
6. 当你看到Bill Gates, 你会对他说些什么？
If you bring friends from other schools, the
teacher will ask them to leave.
If you don’t finish your homework, your mother
won’t let you play computer games.
What will you say to Bill Gates when you see him
1. be＋doing形式: 用现在进行时态表达将来，
主要意义是表示按计划、安排即将发生的动作，
常用于位置转移的动词, 如go、come、leave，
start、arrive等, 也可用于其它动态动词。如：
The president is coming to the UN this week.
总统这周将到联合国来。
We are moving to a different hotel the day
after tomorrow. 我们后天将换一家宾馆。
Explanation
advice意为“劝告；建议”是不可数名词，不能说
a advice, 而是a piece of advice,也因为advice是不可
数名词。“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。我们也可以说为
some pieces of advice一些建议。
如：Can you give me some advice
你能给我一些建议吗？
