高中英语作文万能句子
英语写作万能公式 1. 开头万能公式一：名人名言有人问了，“我没有记住名言，怎么办？尤其是英语名言？”，很好办：编！原理：我们看到的东西很多都是创造出来的，包括我们欣赏的文章也是，所以尽管编，但是一定要听起来很有道理呦！而且没准将来我们就是名人呢！对吧？经典句型：A proverb says, “ You are only young once.” （适用于已记住的名言）It goes without saying that we cannot be young forever. （适用于自编名言）更多经典句型：As everyone knows, No one can deny that…2. 开头万能公式二：数字统计原理：要想更有说服力，就应该用实际的数字来说明。
原则上在议论文当中十不应该出现虚假数字的，可是在考试的时候哪管那三七二十一，但编无妨，只要我有东西写就万事大吉了。
所以不妨试用下面的句型：According to a recent survey, about 78.9% of the college students wanted to further their study after their graduation.看起来这个数字文邹邹的，其实都是编造出来的，下面随便几个题目我们都可以这样编造：Honesty根据最近的一项统计调查显示，大学生向老师请假的理由当中78%都是假的。
Travel by Bike根据最近的一项统计调查显示，85%的人在近距离旅行的时候首选的交通工具是自行车。
Youth根据最近的一项统计调查显示，在某个大学，学生的课余时间的70%都是在休闲娱乐。
Five-day Work Week Better than Six-day Work？根据最近的一项统计调查显示，98%的人同意每周五天工作日。
更多句型：A recent statistics shows that …写作绝招结尾万能公式：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.写作绝招写作的“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, finally9)on the one hand, on th...
求高中英语作文的一些优美句子。
最好是通用的。
.It cannot emphasize the importance of protecting our eyes too much.再怎么样强调保护眼睛的重要性都不为过。
2.I will live up to my end of the deal/ I'll never break my promise.我要兑现我的承诺。
3.To the world you may be one person,but to one person you may be the world.对于世界而言，你是一个人；但是对于某人而且，你是他的整个世界。

2、In ancient times, people celebrated Qing Ming Jie with dancing, singing, picnics, and kite flying.

今年的清明节是4月4日。
在二十四个节气中，既是节气又是节日的只有清明。
清明节是我国传统节日，也是最重要的祭祀节日。
按照旧的习俗，祭祀（扫墓）时，人们要携带酒食果品、纸钱等物品到墓地，将食物供祭在亲人墓前，再将纸钱焚化，为坟墓培上新土，折几枝嫩绿的新枝插在坟上，然后叩头行礼祭拜，最后吃掉酒食回家。

be more specific They are wasting resources, for example, time, energy and money.” 上面这句话不错，只是转折词“for example”不妥当；应该这样： “They are wasting resources. For example, they use too much time, energy and money.” 不然就要换一换转折词，改用“such as”或“like”: “They are wasting resources, such as (or like) time, energy and money.” 不管任何语言，转折词（transitional words）都扮演着一个重要角色，就是：承先启后，使句子紧凑，段落相吸，对文章结构，有良性作用。
但是有些人几乎没有采用转折词的习惯，结果文句松散，上下文七零八乱，应该避免。
现在把主要转折词，分类列下，供大家参考。

高中英语句子分析
第一句是一个复合句，If引导的是一个条件状语从句， people那个是主句，主从句不是并列关系，所以不能加and，起连接作用的词是if。
第二句中and连接的是两个并列句，前面可以加逗号。
and做并列连词时，它前后连接两个相同的语法成分，如动词，名词，形容词，甚至是句子。
如： i'll go to school and study hard. i will call on a friend,and we'll go to museum together. 通常来说，“and＂前后连接两个相同功能的词时，前面不加逗号；而连接两个独立的句子时，前面有逗号隔开。
They can also send emails at any time,and get the latest information through the Interent,which is open to both teachers and students in school.另外，and在连接两个不定式的时候，后一个不定式要省略to 如： we'll intend to go home together and play CS. 这是固定的语法习惯。
