step 4 while-listening

Listen to the first part and complete the passage in activity 2.

Let the students read the passage of activity 2 first, and try to fill in the blanks with appropriate words. At the same time, pay attention to the meaning of the new words.

Listen and fill in the blanks. Then check the answers.

Answers: wildlife, loss, protect.

Tell students they will hear the audio dialogue again without pausing. You can choose the first or second part, or both. Ask them to write down just the key words of the dialogue. They shouldn't write down "little" words such as pronouns, articles, and prepositions.

Then in pairs they must compare their notes and reconstruct the original dialogue before reading it to the class. It does not have to be exactly the same, but it must be grammatically correct.

(1) How many elephants are killed on average every day?

Answers: 54

(2) What did Prince William say about China?

Give students a chance to apply what they have learnt in the previous listening activities through a discussion.

What does "Change begins with you" mean?

Suggested answers: It means that if we want things to change, we must change ourselves first and not wait for others to change first. I think it tells us that we must be the change we want to see in the world.

Wrap up and give students opportunities to apply what they have learnt in the previous listening activities through discussion and adapting a role-play.

(2) What is being done to help them?
