语法教学（it as formal subject）GreetingHello, boys and girls. I am glad to see you again. Are you happy today? Thats great. I am so happy to hear that. 1. Lead inBefore our class, let me show you some pictures. Now look at the ppt, what can you see in the first picture? Yeah, we can see some natural disasters. They are very terrible,right? Now lets move on to the second one. There are some homeless children and they lost their home in the disaster. In China, we have a lot of children who become orphans after some disasters. It makes us hurt. So today we are going to learn something about it.2. PresentationClass, please look at the handouts, I have some questions for you. Q1: Whats shocking? Q2: Whats important? Q3: What dont these children know? Now you have three minutes to find the answers of these questions. Then Ill check your answers. OK, time is up. Any volunteers? Who want to have a try? Great, Lisa, please. The first one is “It is a shocking that so little has been done in the past for these children without parents.” How about the second one? Jenny,please. Yeah, It is important to get something done to help them as quickly as possible. And the last one, lets answer together. Great. Many of these children dont know what it is like to wear clean clothes or sleep in a warm bed. Ill write them down on the blackboard. Hmm, guys, please look at the sentences on the blackboard. This time, I need you to work in pairs to find out the real subject of these sentences. You will have three minutes. Now, lets start. OK, times up. Have you got the answers? Jane,please. In the first sentence, the real subject is “so little has been done in the past for these children without parents”, and in the second sentence, the subject is “ to get something done to help them as quickly as possible”. The last one is “to wear clean clothes or sleep in a warm bed”. Do you guys agree with her? Wonderful. I totally agree with her. Thank you. Sit down, please. Guys since you have found the real subject of the sentences, can you tell me the function of “it” in these sentences? Think about it carefully. Err, Mike,do you want to have a try? You said “it” is used as formal subject in these sentences, and only in this way can the sentences keep balanced. Wow, you give us a perfect explanation. Thank you. Class, just as Mike said, in these sentences, “it” is used as formal subject, and the real subject is that clause and to do structure. Its a good way to express things clearly. So you can also use “it” as subject in your own writings. So next,lets do some practice. 4. PracticePlease look at the ppt, here are five sentences on it. Please rewrite these sentences by using “it” as formal subject. Three minutes later, Ill check your answers. Lets begin. Times up. Gina, you please. Yes, You said “Its important to learn English well.” “ Its necessary to wash your hands before meals.” Wonderful. You got the correct answers. When I walk around, I found most of you did a good job. Congratulations. 5. ProductionBoys and girls, since you have master the grammar, this time lets do something challenging. As you know, every year, there are so many natural disasters in China. For example, the typhoon happened in this summer caused lots of damage and many children lost their home. So, please work in groups to design a poster to call on people to think of ways to help these homeless children. You should use “it” as subject in your writings. Clear? OK, you will have 7minutes to prepare. Lets do it. Time runs out. Which group wants to have a try? Wow, Cocos group, please come to the front. Your poster is to help children who lost their homes after earthquake. I like your poster and you use the grammar we have learned today appropriately. Big hand for you. 6. Summary and homeworkHow time flies! Now, guys, lets summarize what we have learned today. The boy next to the window, may you help to summarize what weve learned today? Hmm, today, we have learned a new grammar-it as formal subject. Also, we learn that we should help those homeless children. OK, next is your homework. Please finish the exercises on page 39. Then your can surf the Internet to find out more ways to help children in need. Thats all for today. Thanks for your cooperation. See you. 7.
