From this lesson, it starts with warming up, pre-reading, readingand comprehending part. (As we all know, reading belongs to the input duringthe process of the language learning. The input has great effect on output,such as speaking and writing.) Therefore, this lesson is in the importantposition of this unit. If the Ss can master it well, it will be helpful forthem to learn the rest of this unit.

Part2 Analysis of the students

The students in Senior High School, gradeone have already learned English for years, they can speak and communicate withtheir friends in English. They are moderate, mature and sensitive. They are highlymotivated in learning English and have the ability to learn by themselves.Furthermore, the topic of this unit is about astronomy, which is full ofmystery, the students will have greater interest in learning it. However, thedifferences in english level among students is the biggest challenge. Thereforethe teacher should provide enough background information to make them better understandthe text. Therefore, I will adopt appropriate teaching methods to arouse theirinterest in learning.

Ⅱ. Analysis of the students

Then, I’d like to talk something about mystudents. They already have learned

some basic listening skills, while theyare very unfamiliar to the gravity . Therefore, I will ask them to search moreinformation about the gravity before the class and thus make a good foundationfor this class.
