He tried reading, but that could not make him forget his trouble.他试着看书，但这并没使他忘记烦恼。

It is a comprehensive lesson. It includes three kinds of tenses and two kinds of voices. It shows us it’s necessary to protect the animals.Teaching aims1.Knowledge aims: names of the animals such as manatee, kangaroo, chimpanzee,cheetah; words about description such as furry, enormous , playful, aggressive, gray, spotted, weigh, pound; words about description of animals ‘ situation .nguage aims: describe the creature of the animals and the place where the animalslive . the kinds of the tense.3.Ability aims: listening practice , speaking practice, writing practice.4.Moral aims: protect the animals and protect the environment .Let’s move on to another part, teaching key points. Important points are knowledge aims Knowledge aims are to enable the students to master the words and phrases. And thesentences: How big are the manatees? They are about 10 feet long and weighs 1000 pounds .Difficult points are ability aims . Ability aims are t o improve students’listening and speaking ability by reading and practicing the conversations.Then I’ll talk about next part analysis of the students. The students in Grade 9 know many words and lots of useful sentences . They are familiar with the teacher’s spoken English. It’s very helpful for me . But also they know more about the animals. So we get along well with each other.Next I’ll talk about teaching methods. My teaching methods are task-based approach and situational approach. During my class, I also design some interesting games for them to learn something.Next is the teaching aids. In this class, I’ll use PPT to present many situations for the students. These can get the students’ to be interested in English.Now I’ll talk about most important part teaching procedure. It includes 9 steps.Step1 is warm-up and leading in the new lesson. First ask the students the questions. I say, I’m cold. What about you ? And then greet to some students while shake hands with them or put my arms around them . I did it to make our heart close.Then I’ll use PPT to play an English song Save the Earth for the students and I’ll ask them try to think and answer my question What should we do?

I’ll take the students to the zoo and show many kinds of animals Then show description words of the animals. They are just for leading in the knowledge aims .Step 3 is Group work. After Step 1 and 2 , I give the students some chances to describe the animals using the description words. Those are the language points.Step 4 is playing the guessing game. The students are active so I design the game . It helps me check the students’knowledge and also make the students relaxed. It’s a preparation for next part. Because next part is a little difficult.Step 5 is listening practice. Because we don’t know the words very well. So I encourage the students to have a try or come on. I help them finish them. When we go on 2a, I find we can guessthe answers first . I t’s necessary for us to practice the listening. 2b is the most difficult ofall . So I design the chart by myself.

I t’s helpful for them. And ask them to remember them.Step 8 is a challenge. This part is just checking the students . At the same time it tells the studentsto protect our pandas.Step 9 is summary .
