句子才是灵魂
句子是文章的基本单位,一个好的句子除了能够准确表达作者的意思，还需要简洁生动。
一、句子要简洁
写作要求精练，因为，简洁的表达能起到更加强调的作用。故设法1）避免使用空洞、多余的短语；2）避免过多地使用并列句；3）避免不必要的重复。请看下面各例：
1）Owing to the fact that I had a lot of work to do, it wasn’t possible for me to accept their invitation.
本句要表达的意思很简单，可是一堆空洞的短语使句子显得很累赘，
改为下面的句子就简洁明了多了。I was too busy to accept their invitation.
2) My hometown is a quiet, peaceful place. It is quiet and peaceful because of the small number of people living there.
有时为了构成平行的句子结构或达到强调的目的，我们会重复使用某些词语。但是，无目的地重复会导致笨拙。可改为：My hometown is a quiet, peaceful place because of the small number of people.
二、语言要生动
写作时要吸引读者的兴趣，句子就需生动、充满活力。平淡无味的句子会使人生厌，注意力分散。但要写出生动的句子就必须注意做到：
1.交错使用长短句
长句和短句各有各的特点，长句结构复杂、容量大，能表达比较复杂的内容，叙事具体、说理严密。短句结构简单、短小精悍、明白易懂。在写作中应当交错使用长句和短句，使句子的长短多样化，增加语言的表现力。请看下面的一段话：
I returned to my room. There was a note under my door. It was from Bob. He said he was in the town and looked for a job. He hadn't found anything yet. He added that he was sorry to have missed me.
一连串的短句，读起来使人感到单调乏味，为了使文字更为生动，意义更加明确，可做如下改动：
When I returned to my room, I found a note from Bob under the door. He said he was in the town looking for a job, but hadn’t found anything yet. He added that he was sorry to have missed me.
2.灵活使用多样句式
(1) 既可以用主动式也可以用被动式, 例如:
例1：We use machines not only in industry but in other sectors of national economy as well.
Machines are widely used not only in industry but in other sectors of national economy as well.
(2) 既可以用肯定式也可以用否定式, 例如:
例1： I shall go there unless it rains.
I shall go there if it doesn't rain.
(3) 某些修饰成分既可以用在句子前面也可以用在后面, 还可以用在中间, 例如:
例1： In fact, speaking is one of the most important means of communication.
Speaking is in fact one of the most important means of communication.
(4) 既可以是正常语序也可以是倒装语序, 例如:
例1：A new type of TV sets was among the products on display.
Among the products on display was a new type of TV sets.
(5) 既可以用简单句也可以用并列句或者主从复合句, 例如:
例1：Nowadays a lot of people work in office, spending most of their time indoors.
Nowadays a lot of people work in office and they spend most of their time indoors.
3.恰当使用英语习语:写作时适当地使用习语、成语等也是使语言生动活泼的好办法。如：
The committee refused to listen to our request.
如果被改成The committee turned a deaf ear to our request. 句子生动，增加了文采。
