Grammar
If從句 (2)
一、引導條件狀語從句最常用的連詞是if，常見的if條件狀語從句表示在某條件
下，某事很可能發生。
e.g. If you ask him, he will help you．
如果你請他幫忙，他會幫你的。
If he does not work hard, he will fail his exams．
如果他不努力，考試就要不及格了。
二、If從句的時態
1. if從句用一般現在時，主句用一般將來時。
e.g. If he runs, he’ll get there in time.
如果他跑著去，他就會及時趕到那兒。
2. if從句用一般現在時，主句用情態動詞+動詞原形。
e.g. She may come with us if she arrives in time.
如果她來得及時，就可以和我們一道去。
三、if 引導的條件狀語從句位置靈活，可直接放在主句后面，也可以放在句首。放在句首時，從句后面要用逗號和主句隔開。
e.g. I’ll go to see you if I have time.
如果有時間，我就去看你。
If it rains tomorrow, we’ll stay at home.
如果明天下雨，我們就待在家里。

I am a good girl but I am not good at studying. I like watching TV so much that I can’t stop myself from watching it.

Yours, Mary
