⑤ 英语四级作文经典句式
1． 结尾万能公式一：如此结论
说完了，毕竟要归纳一番，相信各位都有这样的经历，领导长篇大论，到最后终于冒出个“总而言之”之类的话，我们马上停止开小差，等待领导说结束语。也就是说，开头很好，也必然要有一个精彩的结尾，让读者眼前一亮，这样，你就可以拿高分了！比如下面的例子：
Obviously（此为过渡短语）, we can draw the conclusion that good manners arise from politeness and respect for others.
如果读者很难“显而见之”，但说无妨，就当读者的眼光太浅罢了！
更多过渡短语：
to sum up, in conclusion, in brief, on account of this, thus
更多句型：
Thus, it can be concluded that…, Therefore, we can find that…
2． 结尾万能公式二：如此建议
如果说“如此结论”是结尾最没用的废话，那么“如此建议”应该是最有价值的废话了，因为这里虽然也是废话，但是却用了一个很经典的虚拟语气的句型。拽！
Obviously, it is high time that we took some measures to solve the problem.
这里的虚拟语气用得很经典，因为考官本来经常考这个句型，而如果我们自己写出来，你说考官会怎么想呢？
更多句型：
Accordingly, I recommend that some measures be taken.
Consequently, to solve the problem, some measures should be taken.
写作的“七项基本原则”
一、 长短句原则
工作还得一张一驰呢，老让读者读长句，累死人！写一个短小精辟的句子，相反，却可以起到画龙点睛的作用。而且如果我们把短句放在段首或者段末，也可以揭示主题：
As a creature, I eat; as a man, I read. Although one action is to meet the primary need of my body and the other is to satisfy the intellectual need of mind, they are in a way quite similar.
如此可见，长短句结合，抑扬顿挫，岂不爽哉？牢记！
强烈建议：在文章第一段（开头）用一长一短，且先长后短；在文章主体部分，要先用一个短句解释主要意思，然后在阐述几个要点的时候采用先短后长的句群形式，定会让主体部分妙笔生辉！文章结尾一般用一长一短就可以了。
二、 主题句原则
国有其君，家有其主，文章也要有其主。否则会给人造成“群龙无首”之感！相信各位读过一些破烂文学，故意把主体隐藏在文章之内，结果造成我们稀里糊涂！不知所云！所以奉劝各位一定要写一个主题句，放在文章的开头（保险型）或者结尾，让读者一目了然，必会平安无事！
特别提示：隐藏主体句可是要冒险的！
To begin with, you must work hard at your lessons and be fully prepared before the exam（主题句）. Without sufficient preparation, you can hardly expect to answer all the questions correctly.
三、 一二三原则
领导讲话总是第一部分、第一点、第二点、第三点、第二部分、第一点… 如此罗嗦。可毕竟还是条理清楚。考官们看文章也必然要通过这些关键性的“标签”来判定你的文章是否结构清楚，条理自然。破解方法很简单，只要把下面任何一组的词汇加入到你的几个要点前就清楚了。
1）first, second, third, last（不推荐，原因：俗）
2）firstly, secondly, thirdly, finally（不推荐，原因：俗）
3）the first, the second, the third, the last（不推荐，原因：俗）
4）in the first place, in the second place, in the third place, lastly（不推荐，原因：俗）
5）to begin with, then, furthermore, finally（强烈推荐）
6）to start with, next, in addition, finally（强烈推荐）
7）first and foremost, besides, last but not least（强烈推荐）
8）most important of all, moreover, finally
9）on the one hand, on the other hand（适用于两点的情况）
10）for one thing, for another thing（适用于两点的情况）
建议：不仅仅在写作中注意，平时说话的时候也应该条理清楚！
六、 多变句式原则
1）加法（串联）
都希望写下很长的句子，像个老外似的，可就是怕写错，怎么办，最保险的写长句的方法就是这些，可以在任何句子之间加and, 但最好是前后的句子又先后关系或者并列关系。比如说：
I enjor music and he is fond of playing guitar.
如果是二者并列的，我们可以用一个超级句式：
Not only the fur coat is soft, but it is also warm.
其它的短语可以用：
besides, furthermore, likewise, moreover
2）转折（拐弯抹角）
批评某人缺点的时候，我们总习惯先拐弯抹角说说他的优点，然后转入正题，再说缺点，这种方式虽然阴险了点，可毕竟还比较容易让人接受。所以呢，我们说话的时候，只要在要点之前先来点废话，注意二者之间用个专这次就够了。
The car was quite old, yet it was in excellent condition.
The coat was thin, but it was warm.
更多的短语：
despite that, still, however, nevertheless, in spite of, despite, notwithstanding
3）因果（so, so, so）
昨天在街上我看到了一个女孩，然后我主动搭讪，然后我们去咖啡厅，然后我们认识了，然后我们成为了朋友…可见，讲故事的时候我们总要追求先后顺序，先什么，后什么，所以然后这个词就变得很常见了。其实这个词表示的是先后或因果关系！
The snow began to fall, so we went home.
更多短语：
then, therefore, consequently, accordingly, hence, as a result, for this reason, so that

希望能帮到你。
