i think/believe you should…
sj:i don't think it is necessary to do sth.….we must decide….
sk:i hope we can make a decision.
(teacher writes all the expressions above on the bb.)
t:now let's have a discussion,using the expressions on the blackboard later,i'll ask some students to act it out.
sample diaolgue:
sa—villager a;sb—villager b;
sc—villager c;sd—villager d
se—the village leader
se:as we all know,we are given a large piece of land.i've got all of us here to have a discussion and decide how to use the land.please give us your advice.
sa:i advise we should grow corn on this piece of land.it's large and flat and machines can go up and down it,so we can spend less time and get more corn.a lot of  money can be made after selling the corn.
sb:i think we ought to build a farm there and raise pigs or cows with the grain we harvest.so we can make more money.
sc:my advice is that we should turn it into a garden,and grow flowers there.then we can sell the flowers.there is nobody here selling flowers.so i think our business will surely be good.besides,sometimes selling grain or meat is hard,for the price could be too low.
sd:i think we'd better design it like this:we build a building of a few floors.in each floor,we can raise one kind of animals.with their wastes,we can raise fish or grow vegetables on the top or in the space which faces the sun.we can also grow mushrooms in the dark places.we can use one quarter of it to do this and build a garden on one quarter so that people can enjoy themselves here.half of the rest grow flowers to sell and for the other half we can grow grass on it so that our environment will be better.
sa:that's a good idea.but it will need a lot of money to do this.i hope we can make a decision today.
se:we must make a decision.my opinion is that we do as sd said.any other opinions?
