Dear Kate:
I'm happy to see the E-mail from you.I knew that you would go to China to study Chinese.As to how to study Chinese well, I have some ideas for you. Firstly, you should practice reading Chinese words aloud as much as you can. And you can talk with your friends everyday. Besides, you also can join a Chinese club to make friends with Chinese people to improve your Chinese-speaking. I wil teach some Chinese knowledge for you if possible. I hope you can learn Chinese well and have a good time in China.
Yours,
Li hua

我建议你先学《论语》最好是黄山书社的版本带翻译的.
同时买一本5年高考3年模拟,把其中的基础部分对照解析看三遍.然后,买一本甘肃教育出版社的《征服阅读》古文和现代文在一起的那本,每天坚持练习一到两篇.肯定会上来的.
有问题,我会及时给你解答的,要有信心,勇往直前!

Peter,
I'm glad to receive your letter and learn you

By the way, it's hot here in summer. It's nece

Regarding paypal, I don't have the account, so I have to get an angency to pay on my behalf. Do you think it is OK? About my credibility, you can consult with TAP and Pod as well as Vin in Germany. You can ask them about me (I've made transactions of over 1500 euros with them), if there are no problems about that. I'd like to buy four apple products. If everything goes well. I'd like to cooperate with you regularly. Please tell me what you think about it. Thanks.

设周大爷准备储蓄的这笔现金是x元：

2年期利息 1一年期第一年利息 1一年期第二年利息
得出：8.8%x-3.5%x-3.6225%x=335.5
得出1.6775%x=335.5
得出x=20000
周大爷准备储蓄的这笔现金是20000元

H2SO3是一种弱酸,在不同PH值下有H2SO3、HSO3-、SO3 2-三种形体共同存在,HSO3-呈弱酸性,SO3 2-则呈弱碱性,PH值不同,三种形体在溶液中的分布系数也不同,三种形体的分布系数计算方法如下：
a（H2SO3 ）= H * H / A
a（HSO3-）= H * Ka1 / A
a（SO3 2-）= Ka1 * Ka2 / A
式中：H表示溶液中H+的浓度
A=H * H + H * Ka1 + Ka1 * Ka2
已知H2SO3的离解常数Ka1=1.3*10-2 Ka2=6.3*10-8
当溶液PH=8.0时,溶液中H+浓度=1.0*10-8
计算出的分布系数分别为：
a(H2SO3)=1.05*10-7
a(HSO3-)=0.137
a(SO3 2-)=0.862
当知道NaHSO3的分析浓度后,根据各自的分布系数即可计算出溶液中HSO3-及SO3 2-的浓度,
溶液中加氢氧化钠的作用是调整PH值,控制HSO3-及SO3 2-的比例.

设原价为x万
由题意得一次性付清房款房价为（1-10%）x=90%x=0.9x

由题意可得1.15x-4=0.9x
解得x=16
所以这套房子原价16万元

如果是同时三个医生看的话,小明只要等待5分钟、小立等待2分钟；等待的时间也可以忽略不计；两个医生看的话,小明和小涛看同一个医生的话：小明先去,那小涛等3分钟；小涛先去,小明等8分钟；如果小立和小明同看一个医生的话：小立先去,那小明等6分钟；小明先去,小立只要等3分钟即可；如果小涛和小立去看同一个医生的话：小立先去,小涛要等6分钟；而小涛先后的话,小立要等8分钟；一个医生看的话：如果小明先看,那么小涛和小立只需等3分钟；如果小涛先看,那么小明和和小立需要等8分钟；如果小立先看的话,那么小明和不涛需要等6分钟.还真是绕口呢.

呵呵 多元函数可导啊~ 这么说吧 我们举一个最简单的例子 f(x,y)=X+Y 这个函数对于 x 和 y 的偏导（函）数 都是 1 对吧? 但是对于 x 的偏导 是在将y视为 常数的情况下得出的 同理 y的也是一样 我们通过 逼近 来理解的话 就是这样： 假设 要求 此函数 在原点的 x的偏导数 就是将 纵坐标 当成0 横坐标 不断逼近 0 的结果 而y的偏导数 就是将 横坐标 当成0 纵坐标 不断逼近 0 的结果 即是 沿着一条直线 不断趋近 所得到的结果 而所谓的函数 可导 条件将会苛刻很多 那就是 不管 x y 沿何种方式 （沿曲线啦 抛物线啦 三角函数线啦等等 ） 趋近原点 所得结果尽皆相同 则此函数 在此点有 导数 这就是多元函数的真正意义! 当然 这是理解的方法 不是确切的定义 您对着书 再看看吧……

心情愉快是儿童青少年心理健康的核心．良好的情绪和适度的情绪反应，表示青少年的身心处于积极的健康状态．但是，在日常生活中，遇到不顺心的事，每个人都会或多或少地出现一些情绪问题，如紧张、生气、烦恼等．当出现这些问题时，我们可以试着用以下三种方法来调节自己的情绪．方法一：当情绪不好时，有意识地转移话题，或者做点别的事情，如听音乐、看电视、打球、下棋、外出跑步等，来分散自己的注意力，这样可以使情绪得到缓解．方法二：把自己心中的烦恼向亲人或知心的朋友诉说，把积压在内心的烦恼宣泄出来，这样也会有利于身心健康．但是，要注意宣泄的对象、地点和场合；方法也要适当，避免伤害别人．方法三：当你想得到一件东西，或者想做某件事而未能成功时，为了减少内心的失望，可以找一个适当的理由来安慰自己，这样可以帮助你在挫折面前接受现实，保持较为乐观的态度，综上所述可以知选项B符合题意．

Good afternoon. Welcome to Do Re Me Music Training Class!
Today I’m going to share with you the benefits of music. Researchers acknowledge that certain types of music can aid relaxation by lowering heart rates and blood pressure.
In addition to improving creativity, learning music cultivates many skills that will continue to be useful to your children throughout their lives.
Besides, learning a musical instrument will help your children develop concentration, patience and perseverance, which will help them later in life to tackle difficult challenges. What’s more, practicing musical instruments improves your children’s hand-eye coordination.
Finally, the encouragement of a teacher and the enthusiasm of parents will certainly build in a child a sense of pride and confidence.
That's all! Hope it to be useful for all of you! Thanks!
