Reading for Writing
【教材分析】
The topic of this part is “Present an argument about space exploration”.
This section is about an argument about introducing different benefits of exploring space. Argumentative essays have a stable structure. The first paragraph always presents a certain phenomenon or topic. The body always has the structure of putting up with the supportive or opposing views and their reasons or specific cases. The end always draws a conclusion. In the first paragraph, the author put forward the discussed topic—the benefits of exploring space. In paragraph 2 to paragraph 4, he or she gave 3 pieces of supportive opinions and the reasons or the specific cases. In paragraph 5, we can come to the conclusion—exploring space provides the world with many different benefits.
Therefore, students should be guided to learn the structure and write an essay like this after reading the argumentative essay. But before doing this, students should understand the main ideas about the article and find the topic sentences of each paragraph.
【教学目标】
1. Read quickly to get the main idea; read carefully to get the detailed information.
2. Learn the characteristics or structures of argumentative essays.
3. Learn to write an argumentative essay.
4. Learn to correct others’ writing.

I think we should be in favor of it because a lot of space technologies have already provided service for us common people, like GPS.
