main theme is global warming so the whole class should be started and finished according to it In this class students can be active in the activities I set for them including listening thinking group work and discussing During the class students work with their partners or teacher tofinish the learning task so they experience a sense of success by showing their opinions by themselves However there is much teamwork in this class but a few students are less confident or shy to take part in the activities Some students even did not prepare well for the class So they need to be given more encouragements and practice Besides the teaching information is too much which makes the teaching time so limited that students do not have more time to think about the questions or express their own ideas Further more during the last part Discussion maybe sometimes we can let students do it by themselves i
