Revision

Ask the students to make a revision of new words.

Let’s learn

Lead students learn the difinition and strucure of conditional sentences.

1. if引导的条件状语从句------定义

If it rains tomorrow, I will stay at home.

If it is sunny tomorrow, they will have a trip.

If he doesn't study hard, he will fail in the exam.

if 引导的句子表示某事发生所需的条件，即“在…条件下，某事才能发生”，在句子中充当状语，因此称之为条件状语从句。

if:从属连词，意思是：“________________________”

主句用____________时态，从句用___________________时态，所以也把if引导的条件状语从句称之为____________________句。

Let’s do

Lead the students to finish exercise.

用所给单词的适当形式填空

①If I ___ (go) to Beijing Zoo, I ________ (learn) a lot about animals.

②If I ______ (arrive) at noon, I ______ (see) the feeding of animals.

③If I ____ (find) the Monkey Hill, I ________ (have) fun there.

④If I _____ (watch) the animals carefully, I ______ (get) enough information for my class report.

⑤If I _____ (finish) my report, I ______ (be) very happy.

Let’s learn

Lead students to learn the usage of conditional sentences.

1. if引导的条件状语从句------位置

If I come to school late, I will miss some classes.

I will miss some classes if I come to school late.

If it rains tomorrow, I will stay in bed.

I will stay in bed if it rains tomorrow.

从句可放在________或_____，但是放在主句之前须有_____隔开

2. if引导的条件状语从句------时态

①如果主句是一般将来时，从句则用__________时。

eg: If it rains（从句），I will stay at home.

   I’ll go with you if you don’t want to go alone（从句）

②主句是含有情态动词 may/ might/ can/ must/ should等的句子。从句要用__________时。

eg: If you want to be healthy, you must/ should eat less salad.

   If you finish your homework, you can go home now.

③主句是祈使句时，从句用__________时。

eg: Please let me know if someone calls me.

   Don't play basketball if you don't finish your homework.

④ “祈使句+and/ or + 简单句”是一个固定结构，此时祈使句相当于一个由if引导的条件状语从句。用and引导的简单句通常表示一个较好的结果；用or引导的简单句表示一个不愉快的结果.简单句的时态常用__________时。

eg: Study hard, and you will pass the exam.

    = If you study hard, you will pass the exam.

   Hurry up, or you will miss the train.

   = If you don't hurry up, you will miss the train.

3. 注意事项

①在if引导的条件状语从句中，当主句是一般将来时时，不能够使用be going to结构，而要用will。

I’ll help you with your English if I am free tomorrow. 

②在if引导的条件状语从句中不能够使用some，而要用any。

 If you have any questions to ask, please come to my office.

③为了避免重复，条件状语从句中常使用do( does, did ) 来代替上文提到的动作。

- I think I will ride my bike.

- If you do, you'll be late.
