Useful questions
A: I read a news report that animals, especially wild ones,
are at risk when we don’t see them as important to our
world. Do you think we should protect animals and
their habitats
B: Yes, it’s of great importance because they help maintain
　 the balance of our ecosystem. They provide us with many 　
　 things such as food, clothes and happiness.
Sample
A: You’re right. Don’t forget they’ve also led us to key
advances in science and technology. Unfortunately,
some human activities have done much harm to them,
directly and indirectly.
B: What do you mean
A: For example, hunting and fishing directly cause animal
populations to fall, while indirectly, the cutting down
of trees leads to the loss of animal habitats.
B: That’s true, but we can take measures to help save them.
A: Definitely! What do you suggest
B: We can reduce how much beef we eat because forests
are often cut down to make room for cattle farming
and can also reduce our use of wood and paper. Most
importantly, we should call on people to pay attention
before it’s too late. What do you think
A: Agreed! Writing an article about it for the school
newspaper is a good way to start!
