油漆和易挥发化学物品一定要单独存放,并且远离热源.存放这些材料房间的室内空气湿度不能太大,所以房间要不间断地保持通风.因为对于油漆,尤其是聚酯漆和硝基漆来说,如果室内湿度比较大,油漆在涂刷之后容易返白.

寒假期间我经常去看望我的爷爷奶奶.他们都已经70岁了,住在乡下.我可以在那里做很多有趣的事情.我习惯一大清早起床呼吸乡下的新鲜空气.下雪后,我喜欢跟同伴们一起滑雪滑冰.夜幕降临时,我就坐在火炉边,听奶奶讲动听的故事.我也会给她讲一些城里的新鲜事.每次该回城时,我总是恋恋不舍.我确实喜欢乡下的生活.

想要学好高中化学一定要先把课本吃透了,至少书上出现过的知识点要熟记于心,有些课本上没有涉及到的知识则需要靠做题来积累了.首先,记熟基础知识,在这基础上,毕竟化学是属于理科,所以做题这个步骤也是不能少的,当然你如果要做课外题,一定要保证课内的作业已经全部搞明白了,否则先搞懂课内题,因为考试的大部分题目解题思路都是和课内题相关的.课内的题目全部搞明白了,你可以进行自我拓展,建议你一天做五道课外题吧,做完之后不能就忘了,尤其是做错的题目,不管是课内的还是课外的,都要整理在一本本子上,这本纠错本是你考前最好的复习资料.

Save the Wild Animals
Many wild animals are facing the danger of extinction,because the environment that they are living in has changed greatly.For example,with the developmet of cities,the using of insecticide and serious pollution,their living areas have become narrowcr and narrower.Many of the wild animals,now are confronted with food crisis.At the same time,man is killing off species just for getting their fur,skin,horns,teeth and meat.
In order to protect our resources of ecology,people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty.There fore,measures of the following should be taken:pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life,reserves.
Only if we human beings take some drastic measures can wild animals be preserved.
保护野生动物
许多野生动物正面临绝种的危险,因为它们生活的环境发生了极大的变化.譬 如,随着城市的发展,杀虫剂的使用和严重的污染,野生动物的生活区域变得越来越狭小.许多野生动物目前正面临着食物方面的危机.同时,为了获取野生动物的毛、皮、角、牙齿和肉,人类正在屠杀野生动物.
为了保护生态资源,人们应当意识到任何物种的缺失,至少意味着知识资源和自然美的缺失.因此,应采取以下措施：制订污染标准以降低有毒物质；严禁杀害某些稀有物种；应建立国家公园作为野生动植物保护区.
我们只有采取一些有力措施,才能保护野生动物.

⑴台阶数不宜过多,台阶长度要适当,一般以一个台阶垂直开挖到底,保持平台长2.5m-3m为好,易于掌握炮眼深度和减少翻碴工作量,装碴机应紧跟开挖面,减少扒碴距离,提高装碴运输效率.⑵个别破碎地段可配合喷锚支护和挂钢丝网施工.如遇到局部石质变坏,围岩稳定性较差时,应及时架设临时支护或考虑变换施工方法,留好拱脚平台,采用先拱后墙法施工,以防止落石和崩塌.⑶应重视解决上下部半断面作业的相互干扰问题.微台阶基本上是合为一个工作面进行同步掘进；短台阶上下部作业相互干扰大,要注意作业质量监控及安全管理；长台阶上下部作业面已拉开,干扰较少.对于短隧道,可将上半断面贯通后,再进行下半断面施工.⑷上部开挖时因临空面较大,易使爆破面碴块过大,不利于装碴,应适当密布中小炮眼,但采用先拱后墙法施工时,下部开挖应注意上部的稳定,必须控制下部开挖厚度和用药量,并采取防护措施,避免损伤拱圈,保证施工安全.若围岩稳定性较好,则可采取分段顺序开挖；若围岩稳定性较差,则应缩短下部掘进循环进尺；若稳定性更差,则可左右错开,或先拉中槽后挖边旁.⑸采用钻爆法开挖石质隧道时,应采用光面爆破或预裂爆破技术,尽量减少对围岩的扰动.

1、原子的构成
（1）原子是化学变化中的最小粒子.
（2）原子由带正电的原子核和带负电的电子构成,原子核由带正电的质子和不带电的中子构成,核电荷数＝核内质子数＝核外电子数=原子序数.
（3）原子的质量、体积很小,原子在不断地运动,原子间存在一定的间隔.
（4）相对原子质量：以一种碳原子质量的1/12为标准,其他原子质量跟它相比较所等到的比.原子的质量主要集中在原子核上.相对原子质量＝质子数＋中子数.
2、元素
（1）元素：具有相同核电荷数（即核内电子数）的一类原子的总称.（决定元素种类的是核电荷数或核内电子数.）
（2）元素可以组成物质.由同种元素组成的纯净物叫单质,由不同种元素组成纯净物叫化合物.
（3）元素的分类.金属元素、非金属元素、稀有气体元素.
（4）元素符号
①每种元素都用一个国际通用的符号来表示,这种符号叫做元素符号.
②元素符号表示的意义：表示一种元素、表示这种元素的一个原子.（金属元素符号、稀有气体元素符号,还可以表示一种物质.）
（5）元素周期表
①根据元素的原子结构和性质,把它们科学有序地排列起来就得到了元素周期表.
②元素周期表有7个横行,18个纵行,7个周期,16个簇.
3、离子
（1）离子是带电的原子或离子团,离子也是构成物质的一种粒子.
（2）核外电子的排布.金属元素原子最外层电子一般少于4个,化学反应中很容易失去电子,从而带正电形成阳离子；非金属元素原子最外层电子一般多于4个,化学反应中很容易得到电子,从而带正电形成阴离子；稀有气体原子最外层具有8个（He为2个电子）的相对稳定结构.决定元素化学性质的是原子的最外层电子数.
4、化学式与化合价
（1）化学式：用元素符号表示物质组成的式子.化学式表示的意义：①表示一种物质；②表示这种物质的元素组成；③表示该物质的一个分子；④表示该物质一个分子的组成.
（2）化学上用化合价表示元素原子之间相互化合的数目,单质中元素的化合价为0.
（3）应用化合价推求物质化学式的根据是：①这种化合物确实存在；②化合物各元素正负化合价的代数和为0.

Learn to smile
Smile is an attitude to life. In our life, there may be something unpleasant. For example, you fail in an exam; or another time, you are misunderstood by your friends. These unpleasant things may make you feel bad. Then what will you do? Why not learn to smile? Smiling to yourself can bring back your confidence. Sometimes, the greatest enemy is yourself; that’s to say, sometimes, you are beaten by yourself. We should also learn to smile to others. It will help us to get closer to others. So, smile is the most widely understood language.   

一般过去时 一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用，如：then,at that time,at that moment,just now,just then , recently,yesterday,yesterday morning(afternoon,evening),last night, last week(month,year,Sunday,...

我就说说我们这的吧,我刚结束完初二,下学期就奔三啦～

初二下册最在我们这儿,最最主要的就是——从句.分出各种从句类型,但初二下没有深入地学习从句.主要就是这几种：if引导的条件状语从句、原因状语从句、让步、时间、疑问词引导、或者that引导的宾语从句.
简单讲一下吧,首先,宾语从句最最重要的一点就是——从句部分用陈述句语序.（引导词后面的句子就是从句）举个疑问词引导的吧：I don’t know 【what】should I do.【what是引导词】
平时我们问“我应该做什么”肯定这么说：what should I do? 而在宾语从句中,就要将疑问句语序改为陈述句语序.

【that】引导的宾语从句很简单,that引导的必须是一个陈述句,不能是个疑问句,所以啊,肯定得用陈述句语序喽～

if引导的条件状语从句比前面两种而言较难.【当if解释为“如果”时,句子才是一个条件状语从句,才需要遵守下面的约定：】
if是引导词,if之后的那一句话便是从句,从句部分必须用一般现在时,不管它是要表示将来过去还是现在.如果主句用了（即“ 不是if引导的那一句句子,不是if后的那一句句子,if前的那一句句子便是主句）将来时（will……be going to）那么从句部分必须用一般现在时,不管它是要表示将来还是现在.

例句：（这里的if解释为“如果”）
If he comes I will tell you immediately. 【如果】他来,我会立刻告诉你.
分析：
此句的从句部分便是“he comes ”,因为它在if之后.这里其实要表示一个将来时的,如果他来,并不知道来不来对不?但依旧要用上一般现在是.
I will tell you immediately为主句部分,用了将来时,因为它没有紧接着if.

if也可以表示为：是否.
当if表示为是否时,if部分不一定要用上现在时.
比如：I donnot know if he will come（我不知道他是否会来）

原因状语从句其实很简单,通俗来说,就是because引导的从句喽～用法其实楼主早就应该知道的,只是给他起一个名字而已,也不需要特别注意事态,因为because跟陈述句的吧.

时间也很简单啊,就是when、while（while后面的句子要用上进行时【现在进行时、过去进行时……】）、 before, after, as soon as, until, since. 这里要注意一点的是,如果主句是一般将来时,从句只能用一般现在时表示将来意义.和if条件状语从句差不多用法.

让步么,就是because和so不能用在同一句句子中,有了because就不能有so,so就不能用because,同样的,although（虽然）、but也同样.

另外还有一个很重要的就是——直接引语和间接引语.
这种从句并非由主语直接叙述出来,而是通过第三人转述的.实际上间接引语大都是宾语从句,当直接引语为祈使句,陈述句,疑问句被转换成间接引语时,句子的结构,人称,时态,时间,时间状语和地点状语等都要发生改变.间接引语其实就是我们所说的第三人称转述.

直接引语中的第一人称,一般转换为第三人称,如：
　　He said,“I am very sorry.” ——>He said that he was very sorry.
　　直接引语中的第二人称,如果原话是针对转述人说的,转换为第一人称,如：
　　“You should be more careful next time,” my father told me.——>
　 　My father told me that I should be more careful the next time.
　 　直接引语中的第二人称,如果原话是针对第三人称说的,转换成第三人称.如：
　　She said to her son, “I'll check your homework tonight.” ——>
　　She said to her son that she would check his homework that night.
　 　人称的转换包括人称代词、反身代词、物主代词等,如：
　　He asked me, “Will you go to the station with me to meet a friend of mine this afternoon?” ——>
　　He asked me whether I would go to the station with him to meet a friend of his that afternoon.
　　总之,人称的转换不是固定的,具体情况,具体对待.

　直接引语改为间接引语时,主句中的谓语动词如果是过去时,从句（即间接引语部分）的谓语动词在时态方面要作相应的变化,变成过去时范畴的各种时态（实际也是宾语从句的时态要求）

指示代词、时间状语, 情态动词、在直接引语变为间接引语时需要的变化：
this —— that these —— those now —— then today —— that day
can —— could may —— might must —— had to shall —— should

- -累死我了0 0,间接引语、直接引语的例子是从百科上找的.

语法讲一千遍过后的结果往往不是学生更加明白而是更加的糊涂.
语法的学习首先要知道什么时候用这个语法项目以及在什么地方用这个语法项目.
时态往往和说话人的主观表达意图有很大的关系,如进行时会让你的描述生动形象,完成时富含深层次的含义甚至于感情,一般式往往只是毫无目的的简单直陈.
语态其实在汉语中也一样存在,记得小学时候的被动句式和把字句式吗?那就是被动语态和主动语态.
主语从句、宾语从句、表语从句和同位语从句都是名词性从句,说得简单点,这些从句都相当于一个名词,可以当做名词来进行使用.但是所有的从句,不管是定语从句,状语从句还是名词性从句,他们的前面都会有一个连接词,如which, what, when, where,how等等,连接词后面紧跟的往往是一个主谓结构（俗称陈述句语序）.
语法题解题的主要技巧还是要把每个题目当做阅读理解来做,要体会说话人的表达意图,了解其感情色彩,这样才会选择恰当的表达方式.
内容太多,真要讲清楚恐怕至少也得万把字,只能如此了.

Dear Tom,
How're you doing recently?I've heard that you have your own store on ebay,and just am wondering if you would like to sell some hand-made Chinese knots.These knots are all made by me,so the quality is guaranteed.They are bright red color and about 10cm long.They are made from fine Chinese silk,so very luxury feel.In China,we give the knot to family members or friends as a gift,because it is a symbol of good luck.I think you can sell them each for 5 dollars,and even at that price,we can both make profits already.Should you have any questions,don't hesitate to write to me.I'm looking forward to hearing from you soon.

Dear Mr/Mrs Li,
I'm writing to recommend Simon as the Best Student Prize of this term on behalf of the whole class. The reasons are as follows.
First, he has a good memory and does well in writing. He got high marks in all the subjects and has a good knowledge of Chinese history. Second, he likes sports and runs fast. He likes Liu Xiang and often wins in the school sports meeting. Third, he is always ready to help others and thinks more of others than of himself. He always go to the old people's home to take care of the old. Last but not least, he is so brave that he rescued his neighbours from a fire and put out the fire.
Hope you can make a nice choice and best wishe!


Yours,
Jim

pressure to some degree is not necessarily a bad thing. much pressure, however, is harmful to our well-being. Possible results are poor quality of sleep and weakening of memory. Besides, we may get tempersome and unable to communicate effectively with our parents and teachers. Those who have these problems may try to follow the suggestions below:
First, find out what exactly is making you anxious and stressed. Make a practical yet concrete plan on how to solve the problem. If you cannot do it yourself, resort to your friends and elders because they would be ready to help you.
Second, arrange your time well so you can take a rest . Watching a show or wandering in a park may help relieve your nerve. During recreation or rest , do not think of the pressure you are experiencing, instead, let your heart free at least for that period.

My friend
I have a good friend. Her name is Kate. She is thirteen years old. She likes singing and likes Children’s Day best. But she never eats hamburgers. Because she thinks they are not good for her healthy. She often eats vegetables. She usually goes to school on foot. Look, she is dancing with her friends now. Let’s join them.

本篇作文主要介绍自己叫做Kate的朋友，围绕朋友的简介和兴趣爱好。因为字数要求，对于朋友的爱好简单解释了一下，字数就够了。为了爱好层次分明用了连词but，使文章更连贯。

功率就是单位时间内所作的功,用功率表示做功的快慢.功：W=FS=Pt 功率P=W/t=Fv 能够灵活推导公式就没什么难的

语法 不是一朝一夕能够学好
这里我建议楼主：首先,学会怎么分析一个句子的 主谓宾,
然后 ,再学会找枝叶,即 定状补
定语修饰限制名词 状语修饰谓语 补语一般是对宾语的补充说明
这里一言难尽, 可以在百度知道多多提问碰到问题以后,然后再思考!

Last saturday,our class managed an activity to dong river.We leave for dong river at about 8 am on our school gate.When we fininally reached the river ,everyone seemed to be absorbed in its beautiful scenery,it was all so attrative and so comfortable when we looked at them.
However,there was something uncompatable happen,that was,many visitors throwed the rubbish anywhere.It is a common sense that we shoule live in peace with environment ,once we broke down this connection ,we ought to be punished.
I suggest that there should be more dustbin in it,thus ,the visitors can throw the rubbish easier.
touching with the nature is really a wonderful thing,I look forward to visiting a another nutural scnenry.

Good afternoon,everyone !I think it is our duty to keep our school clean because everyone likes to study in a beautiful environment.In order to keep our school clean,we should do the following.Don't spit and throw rubbish on the ground.We should use a handkerchief when we want to sneeze.We shouldn't pick up the rubbish and throw it into the dustbin.Please don't write or draw on the wall.We should clean our classroom and the school yard carefully.I am sure if everyone makes a contribution to our school,it will clearer and more beautiful.
That's all.Thank you.
