二、如何限题和写提纲

定题：选择恰当的题目。

命题："Teaching"

过于笼统：Teaching

仍较广泛：Teaching Number Concept

范围缩小：Teaching Number Concept to Children

范围明确：Teaching Number Concept to Children at Five

命题"Child Behaviour"

过于笼统：Child Behaviour

仍较广泛：How Children Play Together

范围缩小：How Girls Play Together

范围明确：Patterns of Play Among Primary School Girl Students

写提纲的好处：

1. 可以扩大思路

2. 可以按次序排好素材

3. 将文章分成段

4. 明确写作的中心思想

The Advantages of Travel

Travel is beneficial to us in at least three ways.

First, by traveling we can enjoy the beautiful scenery in different places. We will see with our own eyes many places read of in books, and visit some famous cities and scenic spots.

Second, we will meet people with different interests and see strange and different things when we travel. We can get ideas of the conditions and customs of other people, taste different foods and local flavours if we like. In this way, we can understand how differently other people live.

Third, travel will not only help us to gain knowledge of geography and history and other knowledge, which arouses the fervent love for our motherland, but will also help us keep healthy and make us less narrow-minded. Travel does benefit us both mentally and physically.

With all these advantages of travel, it is no wonder that travel has now become more popular than ever in China.

在写100字左右的作文，我们也强调三段论。第一句话或第一段我们强调我们要写的内容，第二段找一些例子阐述一下。第三段再次把我们强调的内容引申的说一下。
