One day I would like to be a teacher.I always believe that rewarding good behavior is a great place to start.For example,if every student scores more than a 80 on the test,no homework for anyone in that subject.If everyone got a perfect score we would take a poll of where to go for a field trip.But if no one can get over a D then we will have to increase the homework load because students are not learning and need to.No homework for anyone in that subject在句中做什么？为什么没有主胃额，写得有些口语。。。no homework will be given for anyone in that subject.
