Grammar Focus: if 条件句
if引导一个条件状语从句时，当主句是一般将来时态时, if引导的从句必须用一般现在时态来表示将来可能发生的动作或存在的状态。
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, 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 +…

1. 结构
For example:
If you study, I’ll be happy.
wear jeans to school, you’ll be sorry.
get up late, you’ll be late.
eat too much, you’ll be fat.
wash your clothes yourself…
有时，我们可以使用并列结构的祈使句来表达if引导的条件句。如：
If you set your alarm clock, you won’t oversleep.
如果你定闹钟, 你就不会睡过头了。
Set your alarm clock, and you won’t oversleep.
2. 用法
(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: 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, 时态需根据语境而定。
I don’t know if it will rain tomorrow.
我不知道明天是否会下雨。

Write a story with your group on a piece of paper. The first person begins the story with “I think I will …” The others add sentences with “if”. Pass the paper around twice. Then read the story.
I think I will go to the movies tonight. If I go to the movies, I won’t finish my homework. If I don’t finish my homework…
3c
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。
【探究·导学】
在英语中, 有相当多的动态动词都可以用现在进行时表示将来。例如：
Dinner is ready. We’re having fish for dinner.
晚饭好了, 今晚我们吃鱼。
I’m spending my holidays in Singapore this year.
今年我要去新加坡度假。
Tom isn’t finishing his high school until next year.
汤姆明年才高中毕业。
2. Can 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。如：
Can you give me some advice
你能给我一些建议吗？
与advice有关的一些词组：
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
