谁都有坏习惯，我也有一个坏习惯，就是上课不认真。

everyone has bad habits. i also have a bad habit, that is, i don't take classes seriously.

有一次上课了，我在桌板下玩来玩去，被老师骂了一顿后，我眼泪都流出来了。我下定决心，一定要把这个坏习惯改掉。可是，我想了想问题又来了，怎么才能把坏习惯改掉呢？哦，有了，就是每天坚持住就行了。

once in class, i played around under the table. after being scolded by the teacher, my tears came out. i'm determined to get rid of this bad habit. but when i think about it, how can i get rid of my bad habits? oh, yes, just hold on every day.

今天上课的时候，我看着黑板上的字，认真听了老师说的每一句话，我还积极发言呢！下课了，老师还表扬了我。

today in class, i looked at the words on the blackboard and listened to every word the teacher said. i also spoke actively! after class, the teacher praised me.

今天真开心呀，我能改掉上课不专心的坏习惯，就能变得更棒了。

today, i'm so happy. i can get rid of the bad habit of not paying attention in class and become better.

今天我还懂得了很多知识，就是想改掉坏习惯就得坚持住。

today, i also know a lot of knowledge, that is, if i want to change my bad habits, i have to persist.
