我原来没订《初中生数学学习》,就是怕白花了冤枉钱.可是,后来我们班有好多人订了《初中生数学学习》以后,以前比我差的同学,现在跟我差不多;以前成绩与我不相上下的同学,现在超过了我.唉, I didn’t originally book “Junior High School Mathematics Learning” and I’m afraid that I’ve spent money. However, after many classes in our class had booked “Middle School Students Math Learning”, my previous classmates who were worse than me are now similar to me; The classmate who is equal to me now surpasses me.
