3. 英语中用if开头的句子结构
If 可以引导宾语从句表示“是否”的含义，也可以引导条件状语从句表示“如果”的含义。你要问时态的话那就要搞清楚它在引导条件状语从句时所用的虚拟语气的问题了。
a. 与现在事实相反的假设
条件从句 主句
一般过去时（be用were） should(would)等 +动词原形
例如：If they were here, they would help you. 如果他们在这儿，会帮助你的。
含义：They are not here, they can't help you.
b. 与过去事实相反的假设
条件从句 主句
过去完成时 should(would)等+ have+ 过去分词
例如：If he had come yesterday, I should / would have told him about it.如果他昨天来的话，我会把这件事告诉他的。
含义：He did not come yesterday, so I did not tell him about it.
c. 表示对将来不大可能发生的事情的假想
条件从句 主句
一般过去时 should/would等 + 动词原形
were+ 不定式
should+ 动词原形
例如：If you succeeded, everything would be all right. 如果你将来成功了，一切都会好的。
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right.
含义：You are not likely to succeed, everything will be what it is now.
4. 每一句用if 开头写小短文五句之内的
If you take this medicine,all your symptoms will fall away.
如果你使用这种药物，你的所有症状将会消失。

如果他表现不好，给他不及格。

If you grasp this rope, I will pull you up.

If you ask him, he will help you.
假如你向他请求， 他会帮助你。
5. 用if 作为每句的开头做一首英文诗（不少于10句）
If I never met you
If you were not that shining
If I could turn my eyes off you
If I could control my heart
If I could stop thinking about you
If we could spent less time together
If I hadn't come to you that day
If you never said you love me too
If we had less sweet memeory
If I could forget you once we had to go our separate ways.
If all of these are only if.
