二、合并调整，句式多样
在连句成文时，往往会出现句式单调、结构重复或语言冗余等问题。一个句子独立来看是好句子，但若置于篇章之中未必是适合行文的好句子。因此，需要对这些句子进行适当调整，完善表达。请看下面的一个片段：
First, you can try to communicate with your parents, and you can communicate with your teachers and friends as well. You can get along better with them in order that you can let out your anger. You will not hurt them or yourself if you do so. Second, it is important to do regular exercise. You can play football or basketball. Third, it is important to keep high mood. You should have good mood every day. You should also renew your spirits and release your stress. You can have a good attitude towards life and enjoy your beautiful life.
这是未加润色而直接合并要点句拼凑成的文章，问题主要表现在表达单调，简单句过多，主要是you can ...，you should ..., it is important ...，这与“句式多样”的要求相去甚远。
为避免此类问题，我们可对句子进行优化组合。
句1和句2可以进行合并为“First, you can try to communicate with your parents, teachers and friends and get along better with them in order that you can let out your anger.”
句3前增加In this way，即“In this way, you will not hurt them or yourself if you do so.”
句4和句5进行合并，同时用of importance替换important，即“Second, it is of importance to do regular exercise, such as playing football or basketball.”
句6改变句子开头方式并优化，即“Keeping high mood is good for our mental health.”
句7、8、9可合并为“You should have good mood every day, renew your spirits and release your stress so that you can have a good attitude towards life and enjoy your beautiful life.”
通过以上调整，整个段落长短句结合，句式更加灵活，多样化，使文章显得更紧凑、更流畅。
综上所述，要想写好一段话，必须遵循两个原则：
1．统一性原则。一段话只能有一个中心，每句话都只能围绕这个中心去阐述，不能随心所欲地添加一些与中心无关的句子。
2．句式多变原则。考生一定要注意句式应灵活多变，避免采用单一的句子结构，切记不要让there be, and, have, think等常见词汇泛滥。书面表达的句子并非越长越好，有时，一个短小精辟的句子也可以起到画龙点睛的作用，因此书面表达的写作讲究长短句结合，各种句式交错使用。如果考生能做到简单句、并列句、三大从句、非谓语动词交替使用，那么就会使文章增色添彩，提升档次，获得阅卷老师的青睐。
