Unit 5 If you go to the party, you’ll have agreat timeSection A1. If you go to the party, you’ll have a good time.条件状语从句常由从属连词if(如果),unless(如果不,除非)等引导。
和时间状语从句一样,条件状语从句用一般现在时而不用将来时,尤其注意主语为第三人称单数时,动词使用单三形式。
if引导的条件状语从句的结构:if+一般现在时,主语+将来时。
e.g.If you ask him, he will help you.If it rains tomorrow, we won’t go to the park.If it doesn’t rain tomorrow, we’ll go to the park.I’ll go with you if I’m free.We won’t go to the party unless they invite us.If you are bored, stop and relax yourself.Nobody can study English well unless he practices hard.2. I think I’m going to wear jeans to the party.If you do, the teacher won’t let you in.(1)do用作代动词,代替上文的动词部分“wear jeans to the party”,为避免重复。
根据时态和主语的人称变化,还可以用did, does作此类用法。
(2)let in意为“让……进来”e.g.Windows let in light and air.You must keep the door closed. Don’t let the dog in.3. Today is too early. If we have it today, half the class won’t come.(1)too“太…”,带否定含义。
课题:If you go to the party,you’ll have a great time!教学目标:1、句型:If you do, you will have a great time; What will happen if they have the party today?....2、词汇:have a great time; take away; all the time; make a living; in order to.......3、if 条件句重、难点:1.掌握句型2.对if条件句的学习以及运用授课内容及步骤:◆◆【知识梳理】1) 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:时态If+一般现在时主语+shall/will+动词原形e.g: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。
