【参考范文】

　　Certainly, every person has bad habits. Some people may be in the habit of speaking rudely; some tend to be deaf to others’ opinions; some are inclined to delay. However, there is no doubt that allowing to be controlled by bad habits does a great harm to personal development.

　　It is not too much to say that it is a destructive behavior to allow to be controlled by bad habits while it is constructive to change unwanted habits. If bad habits are allowed to be developed, they will get out of control and become big obstacles to life or career. For example, a delayed-prone person will hardly restrain himself from missing the deadline. Understandably, he will have few chances to be entrusted with important tasks and then will barely be professionally experienced enough to gain promotion. On the contrary, it is beneficial to change unwanted habits and acquire good ones, because good habits can make people more competent and thus widen the door to success.

　　In summary, bad habits will probably make it impossible for us to achieve our ambitions. Therefore, we should be alert to our bad habits and make persistent efforts to break them.

　　【中文译文】

　　当然，每个人都有坏习惯。一些人可能习惯说话粗鲁，一些人习惯对别人意见充耳不闻，还有一些人习惯拖沓。然而，不可否认的是允许自己被坏习惯控制对于个人发展是及其有害的。

　　毫不夸张的说：允许自己被坏习惯控制是破坏性行为，而改变不想要的习惯则具有建设意义。如果任由这些坏习惯发展，它们会失去控制，变成生活或事业上的巨大障碍。比如，一个有拖延倾向的人很难约束自己在截止日期前完成工作。自然，他将很少有机会被委派重要的任务，也就几乎不会具有充足的专业经验获得晋升。相反，改变不想要的习惯并且养成好习惯是有益的，因为好习惯能让人更有能力，从而面向更为宽敞的成功之门。

　　总之，坏习惯很可能让我们无法实现志向。因此，我们应该警惕自己的坏习惯并持续努力去改正它们。

　　【写作思路】

　　开篇指出虽然每个人都有坏习惯，但是放任坏习惯对于个人发展十分不利。第二段继续论证放任坏习惯对生活及事业的危害以及改正坏习惯的必要性，且举例说明。结尾进行总结，强调主题。
