Yesterday, our class had a discussion about whether junior students could ride electric bicycles to go to school. 25 students of our class agreed with it, because they said that it is convenient for them and it could take less time to go to school. If they took bus, sometimes the bus come late and it might make them late for school. But the other 35 students didn't agree with them. They said it is not safe for the junior students to get to school by electric bicycles, for they are too young. They also said in the morning the traffic was very busy and the students couldn't ride electric bicycles quickly. Besides, there are too much electric bicycles in the street now, they can get hurt easily.
昨天，我们班讨论了关于中学生是否该骑电单车上学的问题。班上25位同学表示赞同，因为他们认为这样比较方便而且更省时。如果他们坐公车，有时候公车来得晚就有可能使他们迟到。但是，另外的'35位同学不同意他们的看法。他们认为中学生骑电单车上学是不安全的，因为他们还太小了。他们还认为早上交通繁忙，学生骑车不能太快。而且，现在路上的电单车太多了，他们很容易受伤。
