公共场合不允许吸烟英语作文【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.

小星常说：“梦想总是遥不可及，努力不一定马上成功，脚踏实地走好每一步即便是失败也是一种收获”。
那年的我们拥有无知的心灵，对一切充满了信心，总是认为自己强大得无人能及，后来那一步的跨越，彻底把我们击醒。我们是强大的90后，我们是无可比拟的未来。
网上、现实中曾传言：80后是靠自己奋斗起步的一代；90后是啃老族；00后的崛起是更高程度的.疯狂。其实90后的我们真的很强大，我们总是靠着：走自己的路让别人说去吧、的宗旨。开始不在乎一切。甚至开始诞生了早恋、游戏狂、吃货、坑爹、土豪……一系列的新名词。90后的我们在别人看来是多么的傻。不知进取、不知孝道…好多骂名出现在我们90后的身上。但我们也有梦想，我们为梦想奋斗的时候，又有几个人看到了，90后的我们太懦弱了，其实每个人心中都想好好孝敬父母，只是不相信自己罢了。不相信自己可以成功、不相信自己会出人头地，只是一味的逃避。90的我们拥有着自己的梦想，但是也该我们奋斗了，在为时不晚的时间内该为自己的未来好好闯出一片属于自己的天地了，我们应该觉醒了。
梦想什么的，要看自己。你是否在记得，你是否在努力，你是否实现。其实实现与否不是很重要，最初的梦想是青涩的，或许不切实际。重要的其实是你实现梦想的路上，你收获了什么，你得到了什么。梦想不是靠努力就一定可以的，你得先去抓住最近的梦想，才能实现最后的梦，一步登天是基本不可能的。记得我最初的梦想还在小学班主任那里保存着，长大后的我一定要怀着梦想的果实去那里拿回梦想。或许现在我还没有实现，一切都只是出口狂言，但是我相信，只要自己肯向前，绝不后退，就一定会到达终点，靠自己的努力，不管用什么样的方式。
我相信梦想不会走远，它就在前面，你愿意向前，总有一天会到达；若你后退，前功尽弃。有一句话说得很好——当你想放弃的时候，想想自己为什么坚持走到了这里。梦想是自己的选择，而你呢？
自己许下的梦想，到了我们自己应该负责时候了。加油，只要坚持、只要相信自己可以，那么我就一定会做到
闯出属于自己的天地。用心带路，我们一定会到达自己的目的地成功是属于那些失败后依然不放弃梦想的我们。

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.

the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
