主题句

　　通过审题，我们知道了写作的思路。下边我们就谈怎么样写。第一步就是要写主题句。主题句是确保不跑题的前提，只有不跑题才有可能得及格分。写主题句最保险的方法就是把各要求句译成英语。例如上述作文的三段主题句分别为：

　　☆ It is very necessary to be a good university student.(议论体主题句)

　　☆ There are several respects of necessities to be a good university student.(说明体的主题句)

　　☆ What I will do in the future is the following.(描述题的主题句)

　　如果要求句是英语就可以把它扩充成主题句，例如这样的一篇做文：

　　Good Health

　　1) Importance of good health

　　2) Ways to keep fit

　　3) My own practice

　　这样的作文的要求句就可以扩展成主题句。扩展后三段的主题句分别为：

　　☆ It is very important to have good health. (将名词importance变成形容词important)

　　☆ There are four ways to keep fit for me.(用there be句型)

　　☆ My own practices are the following.(采用原词)

　　条理

　　保证不跑题是写作当中第一重要任务，第二个重要任务就是条理清楚。对于议论文来说，正反面要清楚。对于说明文来说，1、2、3条要清楚，对于描述文要来， 谁干什么要清楚。就拿上例Good Health来说，第一段保持正反面要清楚就应这样写：主题句(It is very important to have good health.,正面(With good health, we can...),反面(Without good health, we can do nothing. We can't do...)

　　第二段应当这样写：主题句(There are four ways to keep fit.) 从几方面说明： Firstly, we should have our breakfast in the morning. Second, we should have a nap at noon. Third, sports exercises are necessary in the afternoon. And fourth, we could have a pleasant feeling in the evening by listening to the music....)

　　为了使文章更具关于条理性，我们可以用first(ly),second(ly),third(ly)等副词，他们可以使文章的条理性十分突出。作文是主 观性题，要想得高分我们必须把评卷老师考虑进去。评卷老师的时间很短(每份卷子的作文只有一两分钟就要阅完)，所以我们在列条条时最好不用：To begin with, ... After that,... And then,... The next,... The following,... At last ...。因为用这样的词语不利于阅卷老师看出你作文的条理性。

　　第三段应当这样写：主题句(My own practices are the following.)具体情况(主语为第一人称代词I，与第二段呼应) In the morning, I have my breakfast . At noon, I have a nap. And in the afternoon, I always play football. In the evening, I usually listen to the classic music.

　　综上所述，如果我们按以上几节的方法去做，就可以保证及格以上分数。
