作文中十分优美的句子【一】
一个好的主题句是文章成功的一半。不仅文章有主题，段落有纲，句也必有中心。文章失却主题，就会不知所云;落无纲，则一盘散沙，句缺中心，就无意义。所以，在立足于篇章时，一定要首先明确文的主题;在发展段落时，也要首先写好主题句。从PETS三的特点来考虑，主题句最好是置于文首或段首，这样让人一目了然! 以下就是两个实用的开门见山式发展主题句的方法。
●To begin with, we must attach the greatest importance possible to this issue/fact (key word.
●As is well known to all, it is now high time that we took this (topic word into serious consideration.
作文中十分优美的句子【二】
有一次，它在河边打扮着自己美丽的羽毛，一只蝴蝶从孔雀旁边经过说：“孔雀姐姐，你的羽毛”。孔雀一时没听到，以为蝴蝶是跟它比美，就说：“蝴蝶妹妹，你以为你的翅膀就好看一点就跟我比美，我告诉你，我才是这个森林里最美得动物，我有着五彩缤纷的羽毛你有吗？哈哈哈哈！”蝴蝶听了，心里非常恼火，就说：“孔雀姐姐，你太过分了，我相信，总有一天，森林里一定会有比你更漂亮的动物的。”蝴蝶说完，就气着飞走了。孔雀甩着头说：“你有什么资格来教训我，我就不信森林里还有比我更美的动物。
后来，森林国王马上就要过生日了，可是没有谁跳舞跳的最好，国王决定来一场竞赛，选出一名跳舞跳得最好的动物。消息马上就传出了整个森林，动物们听见了高兴的不得了，每天在家里练习跳舞。孔雀骄傲的说：“我一定是这森林中跳舞的最好的动物。”它的话被许多动物听见了说：“孔雀，你实在是太骄傲了，在比赛场上我和你一分高下。”孔雀说：“好啊！”
动物们拭目以待的比赛终于开始了，在比赛场上，有许多动物很不服的`败给了孔雀，有的由于体型太大跳不动......
经过了三天的对比，总决赛终于开始了，国王也来看这次的总决赛，是天鹅和孔雀，孔雀看到了天鹅那洁白柔滑的羽毛说：“天鹅妹妹，你还是别跟我比了，你看你羽毛的颜色只有一片白，你看看我，五彩缤纷多么好看。”天鹅听孔雀的话说：“你别总是用自己的优点来嘲笑别人的缺点。”国王听见，站起来说：“我宣布，这次比赛的优胜者是天鹅。”孔雀听了，很不服的说：“比都没比，为什么说他赢。”国王说：“因为你太骄傲了，所以我说天鹅赢。”国王说完，动物们用热烈的掌声送给国王。
从此以后，孔雀再也不敢骄傲了。
作文中十分优美的句子【三】
好的文章动静结合、张弛有度有节奏感。句式也是一样，要有变化性，这不仅能使文章更生动，也是语言表达方式的需要和表达能力的体现。句式的`变化，主要是要注意两点：
● 不要从头至尾使用一种句型。
● 长短句结合。
由于语言功底的欠缺和惯用思维，很多人写的文章一种句式到头，如：
I think …
I hope…
He does it.
He will take it
这样的文章虽然意思表达出来了，却显得呆板，欠生动。解决的办法是：
1.间或使用主从复句。
Because he is very much determined, he will carry it out this time. (原因
比较：He is very much determined. He will carry it out this time.
2.使用分词结构句。
The weather being fine, a large number of people went sightseeing.
比较：The weather is fine. A large number of people went sightseeing.
Africa is the second largest continent, its size being about three times that of China.
比较：Africa is the second largest continent. Its size is about three times that of China.
3.使用不定式句。
To be or not to be, that is a question. (莎士比亚
To study or not to study, that is much different.(引申
To do it well, you must plan it well.
比较：You want to do it well. And you must plan it well.
4.倒装句
Only when we fully recognize its importance can we have control of its essence.
比较：After we fully recognize its importance, we can have control of its essence.
No sooner had he arrived home than it began to rain.
比较：He arrived home. And it began to rain.
5.失衡句
whether or not he will come is still unknown to all the people present.
比较：No one present knows whether he will come or not.
That he has done it all by himself is known to everyone.
比较：Everyone knows that he has done it all by himself.
当然，句子并不是越长越好，也不是越复杂水平就越高。凡事皆有度。太多长句的堆砌让人觉得是买弄。有时侯，一个短小精辟的句子可以起到画龙点睛的作用。特别是在文末段尾。比如：
●As a creature, every one knows.
●Actions speak louder than words.
●Practice makes perfect.
