大学英语四六级作文必备：主题句的高分写法
导语：主题句是表达段落主题的句子。它用以概括段落大意，要求全段其他文字都围绕它展开。写好了文章的主题句，相当于已经完成了三分之一的工作，一个精彩高水平的主题句能够为你的作文增色不少。下面是小编为大家精心收集整理的主题句的高分写法，希望能帮助到大家!
请看下例：
My mother has passed along to me certain rules for getting along with others. Don't argue with parents; they will think you don't love them. Don't argue with children; they will think themselves victimized. Don't argue with spouses; they will think you are a tiresome mate. Don't argue with strangers; they will think you are not friendly. My mother's rules, in fact, can be summed up in two words: Don't argue.
主题句中提出的 ……此处隐藏593个字……stablish by paying for it, just as you have made it a part of yourself and the best way to make yourself a part of it is by writing in it.
本段的主题句如果没有in which 引出的定语从句，那么two ways 不仅不能起制约作用，而且也不能起导向作用，句子本身读起来也就使人觉得欠缺点什么。
Exercise is beneficial to your heart. A 22-year study was conducted by doctors in California. They found that people who work at physical jobs experience fewer heart attacks than other people. These active people work all the time at moderate speeds, their daily routine gives them an adequate amount of exercise and helps them stay in shape.
"Exercise is beneficial"这是毫无疑义的。但主题句中如不加上"to your heart"来加以control和limit，那就流于空泛。
因此，紧紧把握主题句中controlling idea的导向和制约作用，是短文写作成功关键之一。
