Ⅱ. Analysis of the teaching material
This unit is mainly about astronomy， and the reading passage talks about the development of life on the earth. It shows how life began on the earth by explain a widely accepted theory that the universe started with a Big Bang. The text is well organized in the order of time， and clearly shows the process of how life developed on the earth. As a topic related to science and astronomy， the students have great interests in it. This will help the student to learn about the process of the development of life on the earth.
Ⅲ. Analysis of the students
This is the second term for the students in Senior High School， so they have adapted to the study in High School. Although this passage is about science， students will be interested in the topic and eager to explore more. At the same time it is also a little hard for the students to understand. Lots of words&expressions about science and biology are involved.
So， I will pay attention to the students in different levels， in order to make everyone experience the happiness of learning.
