Step 1. Revision
Ask students to review five different verb tenses and name the five tenses. Ask them to look at the screen．
Show the names of the five tenses on the screen by a projector along with a sample sentence for each.
present progressive: We’ re studying English.
present: I walk to school every day.

Get a student to read the verbs in these sentences. Then get other students to briefly explain what each tense is used for.
Get students to think of two or three more sample sentences using each type of verb. Have several students read their sentences.
Step 2. Section A 1a
This activity introduces the key vocabulary.
Ask students to look at the signs on each animal’s picture. Get one or two students to the class. And read the words to the class. Get students to repeat the name of each animal.
Read the directions to the class. Point to the list of words in the box. Read the words and let students repeat them. Then get different students to explain what they think each word means in their own words. For example: A gentle animal is quiet and not dangerous. A fury animal is covered with soft hair. Ask some students to explain any words students don’t understand.
Have students fill in the answers on their own. As they work, walk around the classroom checking their progress and answering any questions they may have. After students have finished using all the words from the box, let the students write some other words in the blanks below some of the pictures.
Check the answers with the whole class.
Step 3. Section A 1b
This activity gives students practice in understanding the target language in spoken conversation.
Go through the instructions with the class. Read the list of words in Activity 1a. Say: You will hear Ginny and Victor talk about the animals in the picture in Activity 1a. Now please listen to the recording carefully and circle the words on the list that they use to describe the animals.
Play the recording the first time, students only listen. Then play the recording a second time. This time ask students to circle the words they hear on the recording.

Have students look at the sample conversation in the box and get three students to read it aloud to the class.
Tell students to think of an animal that is the same as them in some ways. Ask students to take a few minutes to write down a statement.
Say: You can write a sentence or two that describes how you are similar to the animal you choose. Don’ t say the name of the animal.

Ask students to describe the picture in groups. Then have a student describe it to the class.
Go through the instructions with the class. Say: You will hear two people talking about manatees. Listen and draw a line between each word and its definition.
Read the sample answer. Then say: The word endangered means there aren’ t very many of this animal left in the world. The manatee is endangered because there aren’ t very many of these animals.

This activity provides listening practice u-sing the target language.
Go through the instructions with the class. Ask students to look at the headings in the chart and the blanks next to each heading. Say: You will hear the same recording again. This time listen carefully to what both people say and fill in the blanks in the chart. Get students to call attention to the sample answer. The two people are talking about manatees, so you write the word manatee after the words kind of animal in the chart.
Play the recording again. Get students to fill in the blanks in the chart.
Check the answers with the class.
Step 7. Section A 2c Pair work
This activity provides guided oral practice using the target language.
Ask students to look at the sample conversation in the box. Have a pair of students read it to the class.
Read the instructions aloud to the class. Say: Each pair of students can make a conversation using information from Activities 2a and 2b. Let students work in pairs. As they work, move around the classroom, checking the progress of the pairs and offering help as needed.

A sample answer:
Dear Editor,
After reading the two letters, I realize that I must say something about animals and zoos. I don’t agree with Disgusted. In fact, many animals only eat once a day or once every few days, so feeding them just once a day is not a problem at all. I think zoos are very important to animals. They can stop many endangered animals from being killed or hunted. They can provide man with places for research work. Also we can visit the animals in the zoos to learn some knowledge to protect the animals Sincerely,
×××

Put students in two teams. Let each team work together as they write down some statements showing their viewpoint, using the expressions in the box.
Look at the sample language in the box. Get two students to read it to the class.
A: I think that animals should not live in zoos.
B: I disagree with you. I feel that zoos provide clean and safe places for endangered animals to live.
Ask the two teams to debate in class.
First, call on one team to give a statement. Then get the other team to give a statement that is related to the first statement. Help the teams make several different statements about a single point before going on to another point.
For example:
Team 1: I think that zoos are suitable for animals to live in.
