首要，一个阶段有必要有一个中心即主题思想，该中心由主题句特别是其中的题旨来表达。整个阶段有必要紧扣这个主题(stick or hold to the topic)，这便是

阶段的统一性(unity)。其次，一个阶段有必要有若干推展句，使主题思想得到充分打开，从而给读者一个完好的感觉，这便是完好性(completeness or 

adequateness)。再者，一个阶段不是杂乱无章的，而是有机的组合，语句的摆放顺序有必要合乎逻辑，从一个语句到另一个语句的过渡有必要流通

(smooth)，这便是连接性(coherence)。下面辛达雅思代报小编就对这三个规范分别加以说明。

　　1.统一性

　　一个阶段内的各个语句有必要从属于一个中心，任何游离于中心思想之外的语句都是不可取的。请看下例：

　　Joe and I decided to take the long trip we'd always wanted across the country. We were like young kids buying our camper and stocking it 

with all the necessities of life. Bella bakes the best rhubarb pie. We started out in early spring from Minneapolis and headed west across the 

northern part of the country. We both enjoyed those people we met at the trailer park. Joe received a watch at his retirement dinner. To our 

surprise, we found that we liked the warm southern regions very much, and so we decided to stay here in New Mexico.

　　本段的主题句是段首句，controlling idea(中心思想)是take the long trip across the country。文中呈现两个irrelevant sentences，一个是Bella bakes 

the best rhubarb pie，这一段是讲的是Joe and I，中心呈现一个Bella是不合适的。还有，Joe received a watch at his retirement dinner这一句更是与主题

句不相关。考生在作文卷上常常由于造出irrelevant sentences(不相关语句)而丢分，值得引起留意。再看一个例子：

　　My name is Roseanna, and I like to keep physically fit. I used to weigh two hundred pounds, but I joined the YMCA for an exercise class and 

diet program. In one year I lost eighty pounds. I feel much better and never want to have that much weight on my five-feet frame again. I bought 

two new suitcases last week. Everyday I practice jogging three miles, swimming fifteen laps, lifting twenty-pound weights and playing tennis for 

one hour. My mother was a premature baby.

　　本段的controlling idea是like to deep physically fit，但段中有两个irrelevant sentences，一个是I bought two new suitcases last week，另一个是My mother was a premature baby。

　　从上面两个例子能够看出，native speakers同样会造出来irrelevant sentences。卷面上假如这种语句多了，形成偏题或离题，那问题就更严重了。

　　2.完好性

　　正象咱们前面说得那样，一个阶段的主题思想靠推展句来完成，假如只要主题句而没有推展句来进一步交待和充实，就不能构成一个完好的阶段。同样，虽

然有推展句，但主题思想没有得到相对圆满的交待，给读者一种意犹未尽的感觉。这样的阶段也不能完成其外交功用。例如：

　　Physical work can be a useful form of therapy for a mind in turmoil. Work concentrates your thoughts on a concrete task. Besides, it is more 

useful to work--you produce something rather than more anxiety or depression.

　　本段的主题句是段首句。本段的两个推展句均不能回答主题句中提出的问题。什么是“a mind in turmoil”(心境不平静)Physical work又怎样能改动这种

情况?为什么它能起therapy的效果?读者得不到明确的答案。

若要达到完好就有必要尽可能地简明。例如：

　　It is not always true that a good picture is worth a thousand words. Often writing is much clearer than a picture. It is sometimes difficult to 

figure out what a picture means, but a careful writer can almost always explain it.

　　段首句所表达的主题思想是一种观点，有必要有具体案例加以验证。上述两个推展句只是在文字上对主题作些解说，整个阶段内容空洞，简而不明。假如用

一两个具体的例子的话，就能够把主题解说清楚了。例子下段：

　　It is not always true that a picture is worth a thousand words. Sometimes, pictures are pretty useless things. If you can't swim and fall in the

 river and start gulping water, will you be better off to hold up a picture of yourself drowning, or start screaming "Help"?
