1．习惯是养成的；

　　2．好习惯是福气；

　　3．坏习惯必须克服。

　　[写作导航]习惯不论好坏都是后天形成的，一旦形成，就很难改变；好习惯是祝福，许多成功人士都承认守时、早起、诚实和毅力等是早期形成的；坏习惯如粗鲁、懒惰、说谎、偷盗和诽谤等恶习是我们应努力避免的。

　　[范文]

　　Habits, whether good or bad, are generally acquired. When a person does a certain thing once and again, he is impelled by some unseen force to do the same thing repeatedly; thus a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to shake it off. It is therefore very important that we should take great care in the formation of habits. Some bad habits formed in childhood may remain lifetime. Older persons also form bad habits, and in some cases they are ruined by these bad habits.

　　There are good habits which, when formed in early life, are great blessings. Many successful people declare that they owe much of their success and prosperity to the formation of such good habits as punctuality, honesty, and perseverance in early life.

　　Such habits as rudeness, laziness, stealing and slandering are bad habits. If we want to be useful to society, we ought to keep away from ail these vices, and strive to acquire those habits that are proven to be good for ourselves and others.
