Saving the Earth (reading)A Brief Introduction to this DesignIn this teaching design, I design a piece of reading lesson. The aims I will get are: enable students to learn to outline a passage; help students deal with some good sentence structures; introduce some methods to help them improve their reading ability. Through the Pre-reading let students learn to predict a passages contents. In this part, let them work together, which can train their cooperative learning. In the While-reading, through listening let them outline the text and compare it with their prediction. During the course of analysis, help them deal with some good sentence structures and introduce some methods to help them improve their writing and reading ability. In the Post-reading, I design a discussion, through it, students can further understand the passage and know it pays to protect our environment and let them understand our nations policysustainable developmentunderstand how important it is. It mainly contains these parts in this design. I believe from these activities I can realize my teaching aims: learn to outline a passage, understand some structures, master some reading methods and know the importance of saving the earth.Teaching Aims:1.

When we see the title “Saving the Earth”, Im sure that you can think of a lot of ways to deal with it. Today we will further discuss it. Before we come to the passage, Lets finish the Pre-reading first. In the last unit we have studied how to predict the contents of a passage. Now please predict what will be talked about in this passage according the title. Please discuss it with your deskmate. Then Id like to share your opinion. You have three minutes to do it. If you still have questions, you can raise your hand for help.Ss: (Three minutes later, students give their prediction)Step 3: While-reading (TBL; listening and reading)T: Terrific! You all have done a good job. Now lets come to the passage “Welcome to the Earth Summit”. We will listen to the tape. After we finish listening to it, your task is to divide it into several parts and make an outline of the passage. You can compare your outline with your prediction. Are you sure? OK. Lets listen to the tape carefully.Ss: (After students give their opinion, teacher shows the outline of the passage on the computer screen)Outline:Part 1 (Para. 1):The origin of the Earth Summit and the purpose of holding it.Part 2 (Para.2-3):The contents of the Earth Summit.1).

That is, we have already known the main idea of the whole passage. Next Id like to help you to deal with some good sentence structures and knowledge points. The good sentence structures in this passage you should keep in mind and the knowledge points Ill tell you in the passage you should try your utmost to use them in your practical life. You can try to use them when doing some comprehension. OK. Let enter the text. Please look at the screen first. These sentence structures you should pay more attention to.1). Since then, several Earth Summits have been held and much progress has been made.2). Among the speakers was Chinas Premier Zhu Rongji.3). Without international cooperation, developing countries cannot prosper, nor will sustainable development be possible.4). Only by changing the way we live can we save the earth.5). Not until we know more will we be able to improve the situation.6). There is a good chance that we will see less violence and fewer wars.(If the students are able to understand the sentences well, just pass them. If they are not, I will give them a detailed explanation. If necessary, I will give more examples to let the students understand them better)T: Just now we dealt with some good sentence structures. If we can master them better, it is of great benefit for us to improve our speaking and writing ability. Besides, in this passage, we can still learn some other knowledge points, which can help us with some reading comprehension. So please listen to me carefully and try you best to pay much attention to what I will say. When we do some reading comprehension, we often have trouble in understanding some sentence that is often very important for us to comprehend. But at the same time, the passage will tell us some clues to help us conquer it. The clues include “or”, “,”, “ and so on. An “or”, a comma and a dash are easy to all of us, but they often help us a lot. In the first two paragraphs, you can find them and you can also find how important for us to comprehend some important words. I hope in the future study you can pay some attention to them.Step 5: Discussion (Cooperation Learning)T: We have finished dealing with some sentence structures and knowledge points, so we have had a better understanding
