结尾万能公式

更多句型:

2. 结尾万能公式二:如此建议
Obviously, it is high time that we took some measures to solve the problem.虚拟语气用得要经典,因为老师本来经常考这个句型,而如果我们自己写出来,你说阅卷人会怎么想呢?
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
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
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。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
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)
四、短语优先原则
写作时,尤其是在考试时,如果使用短语,有两个好处:其
一、用短语会使文章增加亮点,如果老师们看到你的文章太简单,看不到一个自己不认识的短语,必然会看你低一等。相反,如果发现亮点—精彩的短语,那么你的文章定会得高分了。其
二、关键时刻思维短路,只有凑字数,怎么办?用短语是一个办法!比如:
I cannot bear it.可以用短语表达:I cannot put up with it.I want it.可以用短语表达:I am looking forward to it.这样字数明显增加,表达也更准确。
五、多实少虚原则
原因很简单,写文章还是应该写一些实际的东西,不要空话连篇。这就要求一定要多用实词,少用虚词。我这里所说的虚词就是指那些比较大的词。比如我们说一个很好的时候,不应该之说nice这样空洞的词,应该使用一些诸如generous, humorous, interesting, smart, gentle, warm-hearted, hospital 之类的形象词。再比如:
走出房间,general的词是:walk out of the room
但是小偷走出房间应该说:slip out of the room
小姐走出房间应该说:sail out of the room
小孩走出房间应该说:dance out of the room
老人走出房间应该说:stagger out of the room
所以多用实词,少用虚词,文章将会大放异彩!
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 enjoy 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
4)失衡句(头重脚轻,或者头轻脚重)
有些人脑袋大,身体小,或者有些人脑袋小,身体大,虽然我们不希望长成这个样子,可如果真的是这样了,也就必然会吸引别人的注意力。文章中如果出现这样的句子,就更会让考官看到你的句子与众不同。其实就是主语从句,表语从句,宾语从句的变形。举例:This is what I can do.Whether he can go with us or not is not sure.同样主语、宾语、表语可以改成如下的复杂成分:
When to go, Why he goes away…
5)附加(多此一举)
The man whom you met yesterday is a friend of mine.I don’t enjoy that book you are reading.Mr liu, our oral English teacher, is easy-going.其实很简单,同位语--要解释的东西删除后不影响整个句子的构成;定语从句—借用之前的关键词并且用其重新组成一个句子插入其中,但是whom or that 关键词必须要紧跟在先行词之前。
6)排比(排山倒海句)
文学作品中最吸引人的地方莫过于此,如果非要让你的文章更加精彩的话,那么我希望你引用一个个的排比句,一个个得对偶句,一个个的不定式,一个个地词,一个个的短语,如此表达将会使文章有排山倒海之势!
Whether your tastes are modern or traditional, sophisticated or simple, there is plenty in London for you.Nowadays, energy can be obtained through various sources such as oil, coal, natural gas, solar heat, and the wind and ocean tides.We have got to study hard, to enlarge our scope of knowledge, to realize our potentials and to pay for our life.(气势恢宏)
要想写出如此气势恢宏的句子非用排比不可!
七、挑战极限原则
既然是挑战极限,必然是比较难的,但是并非不可攀!
原理:在学生的文章中,很少发现诸如独立主格的句子,其实也很简单,只要花上5分钟的时间看看就可以领会,它就是分词的一种特殊形式,分词要求主语一致,而独立主格则不然。比如:
The weather being fine, a large number of people went to climb the Western Hills.Africa is the second largest continent, its size being about three times that of China.

或含蓄的手法不直接点明作者的看法,而是让读者自己去领会和思考。如“A Day of Harvesting”(收割的日子)的结尾: Evening came before we realized it.We put down our sickles and looked at each other.Our clothes were wet with sweat, but on every face there was a smile.5.用反问结尾 虽然形式是问句,但意义却是肯定的,并具有特别的强调作用,引起读者深思。如 “Should We Learn to Do Housework?”(我们要不要学做家务?)的结尾。Everyone should learn to do housework.Don’t you agree, boys and girls? 6.指明方向,激励读者 结尾表示对将来的展望,或期待读者投入行动。如“Let’s Go in for Sports”(让我们参加体育运动)的结尾: As we have said above, sports can be of great value.They not only make people live happily but also help people to learn virtues and do their work bettter.A sound mind is in a sound body.Let’s go in for sports.文章的结尾没有一定的模式,可以根据表达主题的需要灵活创造。一般的习惯是,一些记叙文和描写文经常采用自然结尾的方法;但说理性和逻辑性较强的说明文和议论文则往往都有结束语,以便使文章首尾呼应,结构完整。
