我基本上会了,但是第二问有疑惑.

同学,你好,你这个求助题,真的有点难,但是既然向我求助,老师也要尽力帮助你.我给你多写了5篇.你随便选吧.

August 6 2012
I have rested for a week. I began to feel bored. So I went out with my friends. They are my best friends in the middle school. We didn’t go to someplace special. We just saw the
other. We had lunch together. While we were having lunch, we were still talking about the new school and new friends. Yes! A year later, we have grown riper. And we learned much more
things and got new life. We haven’t enough time to play, to waste and to lose the way. We only have two years. Two years to go, we will get the real life which belongs to us.
August 7 2012
I have stayed in Shanghai alone for a week. It’s time for me to go to my real home—it is in Beijing. My parents are waiting for me. Although outside is no matter how beautiful, Beijing
is still my home. In fact, there is many fresh things. Like red bayberries. In the afternoon, I took a bus to Beijing. I was very unlucky that my mp3 was stolen. I was very sad. I didn’t know why thieves went to steal other’s things. Why don’t they hunt for a job? I don’t why! I hope there is no thief in our motherland.
August 8 2012
When I got home, it was very dark. Why? There is no electric. Every year in Beijing, there is lack of electric to supply. Because there are a lot of factories. And it is very cold in winter. So the government decided: supply electric to resident and the factories must stop working. My house is in the manufacturing district. I was unlucky. It was very cold. So my father use the electric making machine to make electric. Oh! What a unlucky winter!
August 9 2012
It was cooler than yesterday. One of my father’s friends invited me to eat red bayberries. You must know it is unusual. Because we will climb the hill to eat red bayberries. There is no chance to eat red bayberries in the hill for the people who don’t live in Beijing. On the hill, you can breathe the fresh air, you can listen birds singing and you can eat red bayberries. It was enjoyable. It is said there are wild pigs in the hill. What a beautiful natural.
August 10 2012
Today I found time was a cruel thing. Whatever man is, time always goes on. It won’t stay to wait for somebody. You can’t use anything to exchange time. Time is also a fair thing. Although you have a lot of money or you enjoy high reputation, time won’t leave them more. Today I found I hadn’t enough time. Although I have 50-day holiday, but I found I had a lot
of things to do. I had a lot of homework to do and I had something necessary to do.
August 11 2012
I have rested for 10 days. In these days, I felt very bored. I didn’t know to do what. Although I had a lot of things to do, I felt uncomfortable. I was ill because of the cold weather. I was tired, sleepy and had no strength. My parents are worried about my health. in fact, it didn’t matter. I was always in the room with air-conditioner and opened it in a low temperature. So when I went out, the high temperature disagreed to me. Finally, I was ill.
August 12 2012
Today, when I awaked up, I found the air-conditioner didn’t work. I used the control, but it still didn’t work. I knew the air-conditioner was in trouble. I went downstairs. My father told me two air-conditioner and two computer had been broken. Because my father used electric making machine to make electric, so the voltage was not stable. It led to the trouble. Oh! Whenever the government will let the factory use electric? If it lasts longer, I will be crazy!
August 13 2012
It doesn’t matter that the air-conditioner has been broken. But my notebook-computer also was broken. I really don’t know what to do. So I went to play basketball. I didn’t know any one in that place. And I was the first time to go there to play basketball. At first, there was no person playing basketball. So I played basketball alone. A few minutes later, some students came to play. So we played together. Of course, we had a match. And It lasts two hours. After the match, I felt I would be dead. I was too tired.
August 14 2012
No computer, I will not know to do what. I have no solution to the problem. So I sent my notebook-computer to the Asus computer company. I must have my computer repaired. And the other one, it was thoroughly broken. It can’t be repaired again.The computer company told me that my notebook computer needed one week to repair. The electric led to all trouble.
And many electrical appliances are broken. I don’t know when our country can solve the problem.
August 15 20112
I have lost two computers, but I had another one. I bought it about five years ago. It can be called curio. Though it was old. But it can still work. Although it works slowly, I was pleased. I can go on internet again. Chatting with my friends is a good relaxing. In the internet, one of my old friends invited me to tomorrow’s party. He told me that some friends would go, too. So I promised to go. A-ha! I can see my old friends. I was very happy and hopeful.
August 16 2012
It was sunny today. I was excited. I got up at a quarter to seven. I made a appointment to meet at nine o’clock. After I had my breakfast, I went to the city center of Beijing. It was cold outside. When I arrived, my friends didn’t arrive. I waited for him in front of the KFC’s door. I haven’t seen them for a year. And in a year, we didn’t come into contact with others frequently. About ten minutes left, my friends arrived one by one. After we greeted, we went to the 5-star restaurant to have lunch. The lunch cost us 800 yuan. Oh, dear! They were all very rich, and one was poor.
August 17 2012
Yesterday we played happily, but there were only ten people. I remembered last year there were twenty-two people at all. I heard some my friends had gone abroad. They went abroad to study. Maybe I couldn’t see them in the future. I think next year we won’t make a party. Next year is a very important year. We all will prepare for the college entrance examination. It is the most important for us now.
August 18 2012
I was bored. So I wanted to travel to Hong Kang. I told my father my decision. To my surprise, my father agreed. My father thought I always at home was bad. He thought I should go out to see our country clearly. How beautiful our country is! My father drove me a travel service. I filled out an application form. After that, the agency would finish every things. At last the agency told me it would take a week time to transact procedures.
August 19 2012
The screen of my father’s mobile telephone is broken. When you open the mobile telephone, the screen is always white with light. You can’t see from the screen. And my father is a
businessman. He needed a new one. So my father and I went to the electrical appliance shop. There are many new kinds of mobile telephones. At first, my father chose a Sumsung one.
But all the telephones have sold out. Finally, my father chose a Motorola one.
August 20 2012
The food in Shanghai disagree me. I think the food in Beijing is the most delicious. Seafood in Beijing is very fresh. Prawns in restaurant are all alive. And there are many food that you can’t see in other cities. It is very cheap that you eat seafood in Beijing. The less money you pay, the more enjoyable you are. Maybe my stomach is ill. Whatever food I eat, I am still thin. And I am too thin, I want to be a litter fatter. So I must eat more.

36能做透会拿个好分数的.我的练习过程如下,仅供参考哈
第一步：限时练习,根据自己情况,考试时候是填空和阅读在一起的一共30分钟,填空10个左右吧具体几个忘记了,根据你的填空时间来确定阅读时间,一般是18分钟到20分钟做阅读的时间,限时做一套,一定要限时,不然没用.然后对答案
第二步：肯定是分析错题啦!先分析文章结构,比如立论 ,驳论 ,现象解释等,这个你老G做那么好没什么问题啦,然后是错误类型归类并把他分析好,36套下来基本没什么问题啦!
针对你的问题,我是这样分配的,长阅读一般8~10分钟,短语读分三种,只有一个问题的阅读一般用2分钟,有两个问题的阅读一般用4分钟,有三个问题的阅读一般用5分钟,这样总时间能控制在18到20分钟.
新老阅读我都做了,不过没做过笔记,适合自己的方法就好.
错很多太正常了,第一遍都那样,肯定错的多,等做个2,3遍就好了,越熟练越舒服!慢慢就好了

学校领书的收发室会有的呀,或者问高年级的同学借好了.
新街口的教育书店应该有的吧,我以前缺教科书都在那里买的

你这么说大致上没错,不过凡事总有例外,这里的例外就是非延续性动词不能这么用,而go就是一个非延续性动词.
因为be going to 即可表示近期、主观上或者计划要去做的事,这句应该改为The boy who is going to Beijing is my son.比较好.
还可以说 The boy planning to Beijing is my son.
如果你好奇有哪些非延续性动词,不一定要全部背起来,题做多了,看多了,自然会记住的.

醛有机化合物的一类,是醛基(-CHO)和烃基（或氢原子）连接而成的化合物.
结构
醛的通式为R-CHO,-CHO为醛基.
醛基是羰基(-CO-)和一个氢连接而成的基团.
分类
按照烃基的不同,醛可分为脂肪醛和芳香醛. 芳香醛的羰基直接连在芳香环上.
按照醛基的数目,醛可以分为一元醛和多元醛.
重要反应
银镜反应：
R-CHO + 2Ag（NH3）2OH —（条件：水浴60℃加热）→ R-COONH4 + 2Ag↓ + 3NH3↑ + H2O
与新制氢氧化铜（斐林试剂、班氏试剂）反应：
R-CHO + 2Cu（OH）2 —（条件：加热）→R-COOH + Cu2O↓ + 2H2O
加成反应：
R-CHO + H2 —（条件：镍做催化剂,加热）→ R-CH2-OH
酮
羰基与两个烃基相连的化合物(正式学名为“某基·某基甲酮”).
根据分子中烃基的不同,可分为脂肪酮和芳香酮,饱和酮和不饱和酮.
按羰基数目又可分为一元酮、二元酮和多元酮.
羰基嵌在环内的,称为环内酮,例如环己酮.
一元酮中,羰基连接的两个烃基相同的称单酮,例如丙酮(二甲基甲酮).
互不相同的为混酮,例如苯乙酮(苯基·甲基甲酮).
酮分子间不能形成氢键,其沸点低于相应的醇,但羰基氧能和水分子形成氢键,所以低碳数酮(低级酮)溶于水.
低级酮是液体,具有令人愉快的气味,高碳数酮(高级酮)是固体.
化学性质活泼,易与氢氰酸、格利雅试剂、羟胺、醇等发生亲核加成反应；可还原成醇.受羰基的极化作用,有α-H的酮可发生卤代反应；在碱性条件下,具有甲基的酮可发生卤仿反应.由仲醇氧化、芳烃的酰化和羧酸衍生物与有机金属化合物反应制备.丙酮、环己酮是重要的化工原料

以前我也是这样.完型的话先看一遍文章,把自己确定的空写了,比如一些固定用法啊,常见短语啊,都会有一两个的,然后再把文章看一到两遍,基本上就知道文章说什么了,这样就比较有把握该怎么填了,至于一些不清楚的就靠自己...

什么叫"基本上连续"?
在这里,"基本上连续"的数学意义是:可测函数在其定义域上去掉一个测度任意小的集合后连续
分段函数是有间断点,但其间断点的集合的测度是任意小,所以是"基本上连续"

4500是对的 具体过程马上给你写
设房租X 房间数N 那么Nmin=1 Nmax=50 则Nmin=1时 ΔN=49,Xmax=49*5=295 所以X范围（50,295）
于是有Y=(N-[X-50]/5)*X 注[X-50]为取整的意思 如果是高中的可以不考虑
解它有 Y=-X^2/50+60X 对称轴为 X=150 方向向下 过原点的二次抛物线 最大值在最高点取得 即X=150时候 有Ymax=4500

平常可不是月偏食,那是地球遮住月亮了.
月偏食
月食是自然界的一种现象,当太阳、地球、月球三者恰好或几乎在同一条直线上时(地球在太阳和月球之间),太阳到月球的光线便会部分或完全地被地球掩盖,产生月食.
月食的时候,对地球来说,太阳和月球的方向相差180°,所以月食必定发生在“望”(即农历十五前后).要注意的是,由于太阳和月球在天空的轨道(分别称为黄道和白道)并不在同一个平面上,而是约有5°的交角,因此只有太阳和月球分别位于黄道和白道的两个交点附近,才有机会形成一条直线,产生月食.
月食可分为月偏食、月全食及半影月食三种.当月球只有部分进入地球的本影时,就会出现月偏食；而当整个月球进入地球的本影之时,就会出现月全食.至于半影月食,是指月球只是掠过地球的半影区,造成月面亮度极轻微的减弱,很难用肉眼看出差别,因此不为人们所注意.
月食的过程分为初亏、食既、食甚、生光、复圆五个阶段.
初亏：月球刚接触地球本影,标志月食开始.
食既：月球的西边缘与地球本影的西边缘内切,月球刚好全部进入地球本影内.
食甚：月球的中心与地球本影的中心最近.
生光：月球东边缘与地球本影东边缘相内切,这时全食阶段结束.
复圆：月球的西边缘与地球本影东边缘相外切,这时月食全过程结束.
月球被食的程度叫“食分”,它等于食甚时月轮边缘深入地球本影最远距离与月球视经之比.
月全食的观察
月亮可用肉眼直接观察,不需要什么特别的设备,就可以做以下两项月全食观察.
1.记录月全食的全过程
观察前准备一些观察用纸,纸上画有大圆,圆上按逆时针方向标出0°至360°,0°的位置表示月面的正北点.在月全食发生的过程中,每隔4分钟画一幅月食素描.这样做的结果即可得到一套月全食全过程的食相图.
2.观察月面的亮度与颜色
月食时月面的亮度和颜色可区分为以下5级：0级,非常暗淡,几乎看不见；1级,稍亮,呈黑黄色,细节难以区分；2级,微亮,呈黑红色或棕黄色,中心有些暗斑,外侧相当明亮；3级,呈砖红色,能看见月面细节,但很模糊；4级,呈铜红色,非常明亮,外侧很亮,略有蓝色,可看到大的细节.观察月全食时,要对月面的亮度和颜色的级别作出判断,并记录下来.同时也要记录当时的天气情况.（来源：北京青年报）

我高一基本就什么也没学 到了高二下学期想学学发现什么也学不会 到了高三再想想不学也不行 作为理科生数学绝对不能往下拉分 就强迫自己学
我说一下我的经验希望能帮上你
首先对常用的公式不光要背过 而且对于各种变形一定要熟练 这点很重要 达到了这点可以给做题提供基本的思路 如果一点思路都没有那这个题肯定做不出来的
有辅导书吧 里面的例题全看明白 比较好点的书都有解析也就是做这个题的解答思路分析 这里说的看明白不是这个题会做 而是体会这种题的做法
有错题本最好 但是我相信一般同学是没有那个耐力的 但没有这个不要紧 只要做过的错题懂了之后 过两天一定再重做一遍 如果这一遍很熟练的做出来了 那这种题基本不会再出问题了
最后就是多做题 从最基本的入手 慢慢的加深难度 想要补回来一定要付出比别人多的时间和精力
你现在就全当自己没学过 第一次学 拿出点干劲来 遇到问题一定及时问老师 千万不能攒着 越攒越多总有一个时候就自己放弃了 用不了多长时间我相信会好起来的 只要想学总会好起来的!

北极 南极 北极
习惯上人们把位于北半球的地磁南极叫北磁极,位于南半球的地磁北极叫南磁极.可见地磁的南极和北极与地理的南极和北极是不一致的

先说狭义相对论：在麦克斯韦的电磁理论中光速的描述是没有参照物的,于是爱因斯坦根据物理学家们的实验结果提出两条假设：1所有好的物理定律在不同的惯性参考系中应有相同形式,2光在不同观测者看来应有相同速度.他根据这两条假设,加上近乎完美的逻辑得到了整个狭义相对论,也就是新的物理公式的变换规律,而不是像以前那样速度相加就得到相对速度.但狭义相对论只适用于惯性参考系,我们生活的时空还有万有引力,于是爱因斯坦将其推广,并把万有引力解释为时空弯曲,就得到了在任意参考系都适用的广义相对论,但基本思想还是不变的.

呵呵,其实学习都是有窍门的.我的初高中地理成绩没低过90分,说实话地理很简单.学习自然地理,重在理解,要建立在书本上.简单的说,就是把书本多看几遍,读透吃透知识点.同时,脑子要转起来,想办法让自己兴奋起来,这样学起来就有劲了.要搭配一些练习,要有正确答案的.慢慢做,不要浮躁.把涉及到的不会的知识点记在纸上,重点攻克.做完后对答案,找出薄弱的知识点,再钻研.学习人文地理,重在记忆.不要偷懒,该背的要全背下来.另外,任何一门学科都可联系生活,建议你买一些有彩图的地理杂志,这里推荐《中国国家地理》.通过看杂志培养兴趣,将知识点和地理实际相联系起来,你会发现,自己爱上了地理,兴趣油然而生,学习更不是问题了.我也是选地理的,现在读高三,如果还有问题可以再问我的.以上是我的个人看法,希望对你学习地理有所帮助.

1、预习.预习既是学习方法问题,也是学习习惯的问题.预习的内容很多,如：课前要预习生词、课文和语法内容,在自己不懂的地方作上标记,带着问题有针对性去听课,课堂上尽力去解决自己不懂的问题,如仍不懂,课后应马上问老师.
2、听课.听课是学习过程中最重要的环节,听课效率高的学生往往能够在课堂上掌握教师讲授的大部分内容.听课要做到：紧跟各个教学环节,如复习、引入、呈现、练习和巩固等；要集中精力,听懂教师的讲解,并做好笔记；积极参与课堂活动,如回答问题、对话、角色扮演和复述等.
3、作业.要认真完成课后作业.英语作业分口头和笔头两种.对语言学习来说,朗读、记忆、背诵等课后作业十分重要.
4、复习与总结.课后要进一步理解课上所学的内容,如整理笔记、复习重点和难点；熟读或背诵重要句子；通过归纳、分析和比较,使知识条理化；根据个人情况有针对性地进行复习.
5、自备一本词典.对于重点词汇或易混词要勤查词典,学会用简单的英语去解释生词,其目的在于培养学生的自学能力,以便今后能正确使用英语词典等工具书,准确地理解词义.
自己试着分析结构比较复杂的长句子,如能理解长、难句,那么也就不难理解整篇文章了,这样也随之提高了阅读能力.
6、课外时间尽量多看些课外读物或英语报刊杂志,多读故事类、幽默笑话类材料,以便提高学习英语的兴趣.另外,可以辑一些英语谚语、警句等（如：Practice makes perfect. 熟能生巧；Where there is a will, there is a way.有志者,事竟成）.这样在扩大自己知识面的同时激励自己发奋学习.
7、多说英语,多背课文,培养语感；多写英语,锻炼自己的组词造句能力；课余时间要多与老师交流,解决遗留问题,坚持勤学好问.

没事,我刚开始也是这样,告诉你方法,
做完形,先从头到尾粗略的读,懂得大概意思,然后你要把老师教的一些词的固定用法背会,因为完形的考法之一就是靠你短语用用,看后面的介词与哪个搭配,再者就是,最纠结的,其实我觉得也没多大必要,毕竟你是上高中,没有多大的词汇要求,但是你想提高就多记点,多做点,积累点经验,有时候你看见老是出现的单词,就选呗,考点噻,多做点就好了,不急

黑海和里海之间没有什么海峡也没有运河相连接,这两个地方是分开的.黑海和地中海之间有土耳其海峡相连接,土耳其海峡分为三部分,靠近黑海部分叫伊什坦布尔海峡,靠近地中海部分叫达达尼尔海峡,中间部分是马尔马拉海（世界上最小的海）；地中海和红海之间有苏伊士运河相连接；地中海和大西洋之间有直布罗陀海峡相连接.

不大,比如你初中学了“接触面的粗糙程度相同时,压力越大,滑动摩擦力越大"高中就会引进一个公式,没多大影响

基本和都出现矛盾了!
应该改成“班里同学的作业都交了”

Water contents keep increasing in general

九年级的化学不会难过高中的,那是基础.你要静下心来吧课本看透,结合课后的习题,学习知识不能死板,要多想想这样那样的知识点之间有什么事共通的,老师说的理论知识会导致什么样的现象.有些比较特殊的例子要记着.看书时不要让自己的脑子死往书里钻,想不通的问题时试着让大脑离书本远远地,一一种全局看.注重复习和预习,也许这种话你挺多了,但是认真做了才能有用.最后要记住：学习不是任务,自己去发现学习的乐趣.
