in the University before, I always take an oath devoutly. I must Study hard, make progress every day. And so on it. My mouth which appear in every day. Muddle along without any aimtwo months in summer in the past.
But in came to the University, all the ideas are university fresh washed out immediatelybefore. The daily activities of pressing me out of breath, I asked myself first: my university for what? Experienced a half semester busy, I ushered in the next semester idle tears. In thissemester I more degenerate, the heroic utterance before had left to be flung to the four winds. Every day to the mobile phone waste your life. I suddenly thought of, what is the progress of the times, or degenerate. Later I came to know, not the question of the age. The changes, people's thinking too quick, fast pace of life, created the impetuous social atmosphere.
The big two, determined to change yourself, start from their own English, so the English and minored in class. The spoken English class, only to find how Chinese own spoken language.Learn the English translation, only to find themselves how bad. The speech class, found themselves with completely different before class, the teacher needs to everyone sound, this is not a small challenge for the shy I. But I think this approach the teacher is very good, not only can exercise their confidence, for the pronunciation improve does have great benefits.Once, I stand on the stage to sing, although tone deaf, but I'm still happy. I have successfully taken the first step, I believe that their future will be able to go farther.
I decided to stay away from mobile phones, love life. Do good good study, day day up.

这些表达方式属于非正式用法,常见于口语,有时在歌词中也会出现.
口语中常用,但切忌在写作中使用.

我来说说:)
1.字一定要注意,可以不是特别漂亮,但一定要整齐.最好不要有涂改.写了错字也别涂,他根本发现不了,你涂了是帮老师扣你自己的分
2.高考作文不要试图去创新,有人写古文,有人写诗歌,但是万一得不到满分,就死定了.每一种作文都已经被总结成固定模式了,不要觉得不屑,老师门就喜欢这样的作文
3.多背一些名人名言,但不要总是李白杜甫什么的,烦死了.也不能是卡夫卡之类的太偏的,老师会觉得你是在卖弄.更不能说"古时候有一个人."或者"外国有一个人..." 老师会认为是你瞎编.引用的时候先考虑紧扣文章主题,再想办法给老师一些新意
4.就像楼上说的,不要话太多工夫在作文上.一般40多一点就是好作文了,不需要太钻牛角尖.用这些时间学数学和综合,绝对收获更多
5.写文章前一定要有完整的构思,边写边想肯定完蛋
就这些了吧,作文的变数很大,最后需要的也许就是一点点运气,遇到一个喜欢自己风格的阅卷老师
祝你好运吧!

and the like; or the like; et cetera(etc); et hoc genus omne; (and) what not; things like that;
and all that:最简单的应该是etc

　　1.动词不定式
　　例1：A lot of young people are learning to drive cars.（同时发生）
　　例2：All of us expected to discover a new oil field.（非谓语动词动作发生在后）
　　例3：He is said to have studied English for three years.（非谓语动词动作发生在前）
　　注：动词不定式的完成式有时用在intended,expected,meant,were to,was to等过去式的动词后面,表示未实现的行为.例如：
　　1）I meant to have sent the book to you by mail.（我本想把这本书邮寄给你的.）
　　2）He was to have been the new ambassador,but he fell ill.（他原是要任新大使的,但是他病了.）
　　2.动名词
　　例1：I am thinking of getting a new dictionary.（非谓语动词动作发生在后）
　　例2：We enjoy watching colour TV.（与谓语动词动作同时）
　　例3：He forgot having promised to write things for us.（非谓语动词动作发生在前.）
　　3.分词
　　例1：Singing a song,he came into the room.（非谓语动词动作与谓语动词动作同时发生）
　　例2：Having written his composition,he went to have a heart to heart talk with Wang.（非谓语动词动作发生在前）
　　非谓语动词的比较
　　1.动名词和动词不定式在用法上的比较
　　（1）一般说来动名词所表示的动作在意义上是比较抽象的、一般的,时间概念不强,不是指某一次的动作；而动词不定式所表示的
　　动作则往往是具体的一次行为.例如：
　　1）I like swimming,but I don't like to swim today.
　　2） They prefer staying indoors when the weather is cold.
　　3） Would you prefer to stay at home this evening?
　　（2）动词不定式的逻辑主语,常常是句子的主语或句中的某个词；而动名词的逻辑主语可能是句子主语或句中某个词,也可能是泛
　　指一般人物,在句子里是找不着的.例如：
　　1）I hate to be sitting idle.（我不想闲坐着.）（指自己）
　　2）I hate saying nothing at a meeting but gossiping afterwards.（我不喜欢开会不说会后乱说.）（可能指自己,也可能泛
　　指一般人）
　　（3）有些词后既可接动名词亦可接动词不定式,但意义不同,如stop,remember,forget,neglect,omit,dislike,detests,
　　begin,continue,start,regret,intend,attempt,propose等.例如：
　　When the teacher came in,the students stopped talking.（talking 是宾语,指停止讲话这个动作）
　　When the teacher came in,the students stopped to talk.（to talk是目的状语,指停下前一动作来进行talk）
　　Remember,forget doing something （指已做过的事）
　　Remember,forget to do something （指未做过的事）
　　2.动名词和现在分词在用法上的区别
　　（1）作定语的区别.分词往往表示它所修饰的词所做的动作,即逻辑主语是它所修饰的词；动名词往往表示与它所修饰的词有关的
　　动作,即所修饰的词不能充当逻辑主语.例如：
　　the raging storm （= the storm that is raging） （狂暴的风雨）（分词）
　　scorching heat （= heat that is scorching） （炙人的热气）（分词）
　　sleeping car （= a car for sleeping） （动名词）
　　working method （= method of working）（动名词）
　　（2）作表语的区别.分词作表语时保持它的形容词特征,动名词作表语时保持它的名词特征.动名词作表语时常可与主语互换位
　　置,分词则不行.例如：
　　The novel is interesting.（ 现在分词）
　　My job is teaching English.（动名词）
　　（3）作状语的区别.分词具有副词特征,可以直接用作状语；动名词不具有副词特征,不能单独作状语,只有与介词结合时才能作
　　状语.例如：
　　1） Hearing the news,they immediately set off for the station.（分词作状语）
　　2） Given another chance,I'll do it much better.（分词作状语）
　　3） After finishing his homework,he went to the reading-room.（动名词与介词一起作状语）
　　4） On coming in she laid a file of documents upon the table.（动名词与介词一起作状语）
　　3.动词不定式作宾语补语和现在分词作宾语补语的区别
　　动词不定式只说明宾语的一个动作,而分词则说明宾语的动作正在进行.例如：
　　1）Just then he heard someone sing in the next room.（在那时,他听见有人在隔壁房间里唱歌.）
　　2）Just then he heard someone singing in the next room.（在那时,他听见有人正在隔壁房间里唱歌.）
　　非谓语动词的一般式表示的动作与谓语动词表示的动作同时发生或在其后发生,非谓语动词的完成式表示的动作发生在谓语动词表
　　示的动作之前.

读后感属于议论文的范畴,但又不同于议论文.经常指导学生写有感而发,言之有物的文章,有利于读写结合.它是把读书和写作结合起来的好形式.通过多年的教学,指导学生写好读后感,可从以下几方面下手.读是感的前提,感是读的结果,因此对原作的准确理解,把握住要点,是写好读后感的前提和基础.对原文的阅读是否认真细致,是决定读后感的质量关键.写读后感,不仅有感的内容,也要有读的内容.一般来说,在读后感的开头,都需要用少量的文字先概括介绍一下所读作品的内容,这是因为你所读的作品并不一定为广大读者所熟悉的,不作任何介绍就发表议论会使人感到莫名其妙.而如果精要地作简介,不仅使学生或读者对陌生的作品有所了解,即使对于熟悉这篇作品的读者来说,也能起到激发思索的作用.
首先要想一个读后自己的观点
就是与一般人想得都不一样的
但是还不要都说明
要留下悬念
多设一些疑问句和感叹句

Xi'an was called Chang'an in Han Dynasty.The connotation of "Chang'an" is "a place of permanent peace".It was not until the prosperous Tang Dynasty that Chang'an became famous both at home and abroad as the largest and busiest international metropolis of that age in the world.Xi'an obtained its present name in 1369.It stands first on the six largest ancient capitals.From the 11 century B.C.onwards,Xi'an or its vicinity was established as the capital city by 11 dynasties successively,including the Western Zhou,the Qin,the Han,the Sui and the Tang,and it also served as the capital of two peasant regimes respectively under the rule of Huang Chao and Li Zicheng.The city's capital status lasted for 1,608 years.As regards the number of dynasties and span of time,Xi'an served as an ancient capital beyond compare.
During the Tang Dynasty (618-907),Xi'an was the largest city in the world.Chang'an,was linked to many central Asian regions and Europe via the Silk Road,with thousands of foreign traders living the city.
Xi'an is the capital of Shaanxi Province and also the political,economic and cultural center of the Northwest China.With the development of travel industry and the implementation of the open policy,it has become one of the nation's key tourist cities and tourism has become the mainstay in Shaanxi's economy.
Xi'an lies at longitude 103?east by latitude 34?north,and 412 meters above sea level.It has an average annual temperature of 13鐧?and an average annual precipitation of 604 mm.The rainy season comes in July,August and September.The city now has under its jurisdiction eight districts -- Xincheng,Beilin,Lianhu,Yanta,Weiyang,Baqiao,Lintong and Yangling,and five counties -- Chang'an,Lantian,Huxian,Zhouzhi and Gaoling.As a whole,Xi'an covers an area of 9,983 square kilometers and has population of 5,860,000.The city proper occupies an area 861 square kilometers,and reaches a population of 2,650,000.
With an elevation of 500 metres,the Weihe Plain extends between Baoji in the west and Tongguan in the east and borders the Qinling Mountains in the south and the Huangtu Plateau in the north.Lying in the warm zone,the plain has a temperate climate with four distinct seasons.Chequered with the Weihe,Jinghe,Luohe,and Bahe rivers as well as the Jinghui,Weihui and Luohui canals,the fertile land on the plain has easy access to irrigation facilities and an abundant yield of farm produce.Xi'an lies in the centre to the south of this plain,a favourable geographical location surrounded by water and hills.
The area around Xi'an was inhabited by the progenitors of the Chinese nation as far back as 500,000-600,000 years ago.In the 1960s,archaeologists discovered in Lantian County to the southeast of Xi'an human fossils and cultural relics belonging to the Paleolithic Period.In the 1950s,the remains from the Neolithic Period were discovered at Banpo Village to the east of Xi'an City.In the 70s,the Jiangzhai Ruins from a later part of the Neolithic period were discovered at Lintong County to the northeast of Xi'an City.These archaeological discoveries indicate that the area around Xi'an is one of the cradles of Chinese civilization.
As one of the six ancient capitals in China,Xi'an served as the seat of 12 imperial capitals for 1,120 years after Chinese society had entered the civilized stage.
Xi'an is also a world-famous tourist city,a treasure house of cultural relics.The remains of past civilizations furnish evidence of every major epoch in China's half a million history,making for a particularly illustrative textbook of Chinese culture.The history apparent in Xi'an is so ancient and continuous that the city has no parallel anywhere as a cultural site.Here one can visit the sites once inhabited by its primitive people; admire the bronze wares manufactured in the Bronze Age; wander through the city ruins of the Qin,Han,Sui and Tang Dynasties; imagine for oneself the clamour of the old Oriental metropolis; explore the imperial tombs of the Qin,Han and Tang Dynasties,testimony to the pervasive power of the feudal ruling class; ramble in temples and pagoda courtyards,tracing vestiges of the Silk Road; and study stone inscriptions to appreciate Chinese calligraphy.Not least,Xi'an is the site of excavation of the vast army of terracotta warriors and horses from the tomb of China's First Emperor,Qin Shihuang,from whom the country derives its name.
Xi'an was the starting point of the world-famous Silk Road.It can be well likened to a history museum.Moving around this old city is like going through thousands of years back in time.In this vast museum you will see the Banpo Village Remains of a matriarchal community; the Huaqing Hot Springs which was noted as early as the Zhou Dynasty more than 3,000 years back; Qin Shihuang's terra-cotta warriors and horses,known as the eighth wonder of the world; the imperial cemetery grounds of the Han and Tang dynasties; the Great Mosque with unique features; the Big Wild Goose Pagoda and the Small Wild Goose Pagoda built in the Tang Dynasty; the Bell Tower and the Drum Tower of the Ming Dynasty; and the Forest of Steles with a rich collection of age-old stone steles.

用哪种方法都可以,而且解出来的结果应该是一样或完全等价的,否则你的过程可能有误.
比如y"+4y'=0,特征根为0,-4,故通解为y=C1+C2e^(-4t)
用代换法：p=y',则y"=pdp/dy,代入得：pdp/dy+4p=0,得：dp/dy+4=0,得：p=-4y+C1
即dy/(-4y+C1)=dx
积分：1/(-4)*ln|-4y+C1|=x+C2
得：|-4y+C1|=-4x+C3
-4y+C1=C4e^(-4x),
即y=C5e^(-4x)+C6
两者是等价的.

氢气与盐不能发生化学反应.
你的想法有道理,因为你认为氢在前面,应该可以把后面的金属从它们的盐中置换出来.
如果是在溶液中,氢气不可能把盐中的金属置换出来的.因为在溶液中,氢气虽然有还原性,但是不能电离.氢气要表现还原性,必须在较高温度下才行.
但氢气确实有能力把后面的金属从化合物中置换出来,但该化合物,应该是氧化物,而不是盐.如:
H2 + CuO =加热= Cu + H2O 铜在氢的后面,氢气可以把它还原出来.

席慕容《祈祷词》
我知道这世界不是绝对的好
我也知道它有离别 有衰老
然而我只有一次的机会
上主啊 请俯听我的祈祷
请给我一个长长的夏季
给我一段无瑕的回忆
给我一颗温柔的心
给我一份洁白的恋情
我只能来这世上一次 所以
请再给我一个美丽的名字
好让他能在夜里低唤我
在奔驰的岁月里
永远记得我们曾经相爱的事
席慕容 缘起
就在众荷之间
我把我的一生都
交付给你了
没有什么可以斟酌
可以来得及盘算
是的 没有什么
可以由我们来安排的啊
在千层万层的莲叶之前
当你一回眸
有很多事情就从此决定了
在那样一个 充满了
花香的 午后
际遇
席慕容
在馥郁的季节 因花落
因寂寞 因你的回眸
而使我含泪唱出的
不过是
一首无调的歌
却在突然之间 因幕起
因灯亮 因众人的
鼓掌 才发现
我的歌 竟然
是这一剧中的辉煌

　　“像”与“象”的规范用法
　　一段时期来,汉字“像”与“象”使用混乱,国家语言工作委员会就此作出了规范表述.
　　在现代汉语里,象作为一个单音词,只有指“大象”这样一个意义.作为词素,有两个意义:一、名词性词素,指形状、样子,可构成复合词如“现象、假象、表象、星象、脉象、旱象、形象、印象、怪象、险象、幻象”等.二、动词性词素.指摹仿、摹拟,可构成复合词如“象形、象意、象声、象声词”等.带单人偏旁的“像”,在现代汉语中有三个义项:一、名词,指比照人物等作成的形象,如“鲁讯像”等.二、动词,意指“相似”,如“他像他的哥哥” ．．．

　　“象”和“像”莫混淆
　　孟 祥 军
　　同学们在使用“象”与“像”的时候,经常将这两个字混淆,出现使用错误,下面我们来区别一下它们的用
　　法,以便同学们正确使用这两个字.
　　1.“象”和“像”都作名词.
　　“象”字有两种意思：（ 1 ）指物品或动物,如象棋、大象、象牙等.（ 2 ）指形状、状态,比如现象、
　　景象、气象、印象等.
　　“像”字指照人物做成的制品,一般和人有关,如裾隆⑼?瘛⑿は瘛⒒?瘛⑺芟瘛⒙枷瘛⒁粝竦取?
　　2.“象”和“像”都作动词.
　　“象”字用作动词时,一般指摹拟、模仿的意思,如象声、象形等.
　　“像”作动词的时候,大多是相似的意思,如好像、像母亲、像雷锋等.
　　现在同学们在使用这两个字的时候,最常见的错误是把名词中的“像”（如画像、塑像、录像、音像等）写
　　成“象”；把“象”（如景象、气象、印象、现象、象形等）写成“像”.只要我们搞清楚这两个字作名词或动
　　词时的不同用法,就能够正确使用它们.
　　顺便说的是,过去常常有人写的“照像”、“像片”,现在都应规范为“照相”、“相片”.

我英标不是很好,帮你找了些资料
t读“特”（清音,读此音时,要去掉该中文字“e”的音）,如：take,let
th读“咝”（清音,中文无此音.读此音时,想象一下蛇伸出舌头的样子,但必须上下齿咬
住舌尖,发出清音,发音完成后才松开）,如：think,thank,three,thirteen
th读“嗞”（中文无此音.读此音时,也必须上下齿咬住舌尖,但发出浊音,发音完成后才
松开）,如：this,that,with
tr读“特惹”（两个音连读时要快,前音稍短,后音稍长）,如：tree,truck,train,
trousers
在英语单词中字母p,k,t在s后的读音规则是轻音浊化
s后若跟/t/则/t/变/d/ 例如:stop---/sdop/
/p/则/p/变/b/ 例如:spider---/sbaidэ/
/tr/则/tr/变/dз/ 例如:stride---/sdзaid/
/k/则/k/变/g/ 例如:ski---/sgi:/
单词后面的音标只是读出来的音标,标的话还是按照原来的标,不变的.
注：音标这样写可以看得懂吧,有些音标打不出,例如：/o/这个打不出.

以此类推 we can deduce the rest in the same manner.
