We all have certain kinds of bad habits. For teenagers, it is very important to get rid of bad habits.
　　Let's take the habits of talking in class as an example. If we talk in class, we can't listen to the teachers carefully. Of course we can't understand the teachers, and can't finish our homework easily after class. Some students have to copy others' homework when the teachers ask us to hand it in. Then we will get weak in our school lessons and we will become a bad student in the teachers' eyes. Besides, talking in class maybe influences some other students.
　　So, we must get rid of bad habits at once.
【參考譯文】
　　
　　我們都有各種各樣的壞習(xí)慣。對于青少年來說，改掉這些壞習(xí)慣是非常重要的。
　　讓我們以上課說話為例。如果我們上課說話，我們就不能注意聽講，當(dāng)然不能很好的理解老師所講的內(nèi)容，課后就不能輕易完成老師的作業(yè)。當(dāng)老師要求我們交作業(yè)時，一些同學(xué)不得不去抄襲其他同學(xué)的作業(yè)。然后我們的功課會變得很差，我們將會變成一個老師眼中的壞學(xué)生。不僅如此，在上課說話還會影響其他的學(xué)生。
　　因此，我們必須立刻改掉壞習(xí)慣。
