语法知识
本单元语法： if条件句
if条件句：条件句用于陈述语气，表示假设的情况可能发生，其中 if 是“如果”的意思。
构 成 条件从句 主 句
时 态 If+一般现在时 主语+shall/will+动词原形
例 句 If he comes, he will take us to the zoo.
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。
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.
另外，主句是祈使句或含有情态动词，从句也用一般现在时。如：
Please call me if he comes next Sunday.
Can you call the policeman if you are in the trouble.
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，时态需根据语境确定。如果主句用一般现在时，从句可以根据具体情况选用时态，如果主句用一般过去时，从句必须用过去式的某种形式。
I don't know if it will rain tomorrow. 我不知道明天是否会下雨。
Our teacher said there was going to be a football match the next month.我们说下月将有场足球比赛。
现在进行时表示将来的时间
1. 用be doing 表示将来：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，arrive等， 也可用于其他动作动词，如：
We are having fish for dinner. 我们晚饭吃鱼。
We are moving to a different hotel the day after tomorrow. 后天我们会去另外一个旅馆。
这种用法通常带有表示将来的时间状语，如果不带时间状语，则根据上下文可表示最近即将发生的动作。
A: Where are you going?
B: I am going for a walk. Are you coming with me?
A: Yes, I am just coming. Wait for me.
2. 现在进行时表示将来和用be going to 表示将来意思比较接近，但有区别：(1)、根据已有迹象表明将要发生某事时，用Be going to + v，而不用一般将来时。如：Look at the clouds. There is going to rain.
(2)、表示客观将要发生与主观愿望和判断无关时，用一般将来时。如：
It will be Sunday tomorrow.
He will be 15 next year.
