student is providing a good model for the rest of the class．
Ask students to read the letter again． Then finish the work on their own or in pairs． When they
work, walk around the classroom, checking the progress of the pairs and offering help as needed．
Check the answers． Answers will vary but a good letter will take the points from the letter opposite
to their point of view and argue with them．
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 better．
Sincerely,
×××

Notes
1． living—active: lively
2． care for—look after; provide food, money, shelter, etc．
3． urge—request earnestly; try to persuade; strongly recommend
Step Ⅳ Part 4
This activity provides oral practice using the target language．
Go through the instructions with the class． There will be two different teams． One team will talk
about why zoos are good places for animals and the other team will say why zoos are bad paces for
animals．
Look at the list of expressions． Invite a student to read the list aloud to the class． Then get some
students to use each expression in a complete sentence．
S1 : I think that elephants shouldn’t be kept in zoos．
S2 : I believe that animals in zoos live longer than animals in the jungle．
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． Invite a pair of students to read it to the class．
SA : I think that animals should not live in zoos．
SB : 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 ask 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 not suitable for animals to live in．
Team 2: Why do you think so?
Team 1: Because animals there are only given food once a day． They’re hungry．
Team 2: I disagree with you． I believe that many animals only eat once a day or once every few
days． So, there is no need to worry about that．
Step Ⅴ Summary
In this class, we’ve learned some key vocabulary words such as against, be suitable for, tiny cages, care for, urge．
We’ve also done a lot of reading, writing and speaking practice using the target language．
Step Ⅵ Homework
