说明文写作口诀和范文

口诀：说明文写作注重“序”，依据信息来动笔，时间、空间和逻辑，“三种顺序”选其一。要把说明文写得条理分明，就要掌握一定的说明顺序。常用的说明顺序有：空间顺序、时间顺序、逻辑顺序。空间顺序是指从整体到局部，从上到下，从内到外的顺序；时间顺序是指时间上从先到后的顺序；逻辑顺序是指先因果或先果后因或先主后次的顺序。参照模式：

1、顺序说明法：

These are several reasons why I decided to study in this school.First of all, the students in this school are friendly.Secondly, there is a big library and 3 big computer rooms.Thirdly, there are many finest teachers.Finally, this school is not far from my home.It won’t take me long time to go to school.这段文章介绍了一个学生在这个学校学习的理由。全段层次分明，连接词语（firstly, secondly, thirdly, finally）运用得当。

2、举例说明法

Computers are very important in our lives.For example, they can do many kinds of work.You can get lots of information on them.You can also watch interesting movies and videos.By the way, downloading music is a good choice.We even use them to play computer games at home.Today a lot of people buy computers.Computers are becoming more and more popular.本段文章首先说明了电脑的重要性，然后用for example来举例说明电脑的不同用途。

3、因果关系法

Of all the pets, I like dogs best.I prefer dogs because dogs can do lots of things for people.People keep a dog not only for pleasure but also for safety.A dog can be a guard.In the country, farmers like to keep dogs for pleasure, too.Besides, some of the dogs can help farmers to look after other animals, such as sheep and pigs.Dogs can be a great help to army soldiers and policemen.Dogs often do important work for them.So dogs are really our good friends, and we must take good care of them.第一句是本段的主题句，末句是总结句。在主题句后，作者用连词because引出了句子来阐述自己喜欢宠物狗的理由。
