[參考范文]

The students of our school has a discussion about whether listening test in the National Matriculation English Test should be kept or canceled. Some students think that listening test should not be canceled. They insist listening is among the four basic skills. We therefore can not ignore it. Besides, listening is one of the important channels for us to get information from the outside world. So it should be strengthened today when international cooperation is becoming more and more frequent. But others don’t agree. They think not everyone has to communicate with foreigners in the future, Moreover listening test is unfair to the students in the areas where radio signals cannot be picked up effectively. And for certain reasons, there is a big difference in teachers and equipment between the countryside and the city.
