Dear Mr. Singh,
I’m writing to apologize for any misunderstandings that occurred when I showed you around Beijing the other day.
I felt rather strange when you would not shake hands with me. I did not realize that there are some taboos in different countries and cultures. After reading a magazine article, I know that people from India don’t shake hands with their left hands. I should not have held out my left hand to you. And I know you do not eat beef because of your religion.
I feel very sorry for not having known these taboos earlier. I hope you can forgive me for all these misunderstandings. I hope our next meeting will be happier.
Yours sincerely,
John

Dear Mr. Takashi:
I am writing to apologize for any misunderstandings that occurred when I showed you around Beijing the other day. I notice you were a bit upset when I put the business card you gave me in my pocket without looking at it, and I did not know why you bought so many things.
From reading magazine article, I learnt that Japanese people give out their business cards when they greet others and they would like others to look at their cards carefully, so I should have read your card before I put it in my pocket. I also know why you bought so many things here. Because giving gifts is expected in Japan and on a trip, you must bring back lots of gifts.
I feel very sorry for not having known these cultural habits earlier. I hope you can forgive me for all these misunderstandings. I hope our next meeting will be happier.
yours
sincerely,
Xiao Ming

高中二年级英语学案 Units 3-4 (B2) 【知识网络】 一、重点词汇与短语 1．impress （1）. impress作“铭刻”讲时, 是及物动词. 常用于impress sth on/upon sb “使某人铭记某事物”. 例如: His words impressed themselves on my memory. 他的话铭刻在我的记忆里. （2）. impress还可以表示“给某人留下深刻印象”, 常用于被动语态. 例如: We were deeply impressed by his words. 他的话给我们留下了深刻的印象. His acting impressed me as being somewhat artificial. 他的演技给我的印象是有点做作. （3）. 习语: impress sb with sth.使某人牢记某事. be impressed on one’s mind/memory被印在脑海里; 留下很深的印象. （4）. 同义词: affect v t给……以印象; 影响. 2．close 与closely 的区别 close 和closely 用作副词意义上有差别。 Close 是指距离、场所、地点等的“接近，靠近”，可以说是一种实际意义上的“接近”。 Close to有“接近，几乎，大概，差不多”的意思。 例如： We live close to the church. 我们住在教堂附近。 They sat close together. 他们紧挨着坐在一起。 He came close to losing his temper. 他差一点发脾气了。 Closely 是指抽象意义上的“接近”，多用比喻意义，有“亲密地，严密地，仔细地”等意思。 例如： The secret must be closely guarded. 这个秘密要严加保守。 He is looking at the bill closely. 他正仔细地看着帐单。
【知识要点】一、溶质的质量分数 溶液的浓稀、有色溶液的颜色都可以粗略的表示一定量的溶液中含有溶质的多少，溶液中溶质的质量分数可以准确地表示一定量的溶液中含有溶质的多少。 1.定义：溶液中溶质的质量分数是溶质质量与溶液质量之比。 数学表达式： 特点：无单位、是个比值、一般不受温度的影响等。 饱和溶液溶质的质量分数的计算： （其中S为该温度下物质的溶解度） 2．配制溶质质量分数一定的溶液 以配制100g溶质质量分数为5%的氯化钠溶液为例分析： （1）计算：计算配制100g溶质质量分数为5%的氯化钠溶液所需氯化钠和水的质量。 （2）称量：用托盘天平称量所需的氯化钠。 （3）量取：用量筒量取所需的水（水的密度近似看作1g/cm3）。 （4）溶解：将量好的水倒入盛有称量好氯化钠的烧杯中，用玻璃棒搅拌，使氯化钠溶解。 （5）装瓶、贴签：把配制好的溶液装入试剂瓶中，盖好瓶塞并贴上标签，备用。 操作示意图可简单表示如下： 说明：如果用液体溶质来配制溶质质量分数一定的溶液，其步骤为：计算→量取→溶解→装瓶、贴签。想一想，这是为什么？ 二、关于溶质的质量分数的计算几种类型1．根据定义式的基本计算 （只要已知其中的两个量，就可以求出第三个量） 例如：20克硝酸钾完全溶解在60克水中，所得溶液中溶质的质量分数是多少？ 解：根据溶质的质量分数的定义可得 ＝＝25% 注意：饱和溶液溶质的质量分数的计算： （其中S为该温度下物质的溶解度） 2．溶液的稀释和浓缩问题的计算 根据稀释前后溶质的质量不变进行运算，无论是用水或用稀溶液来稀释浓溶液，都可计算。 （1）用水稀释浓溶液 设稀释前浓溶液的质量为m，其溶质的质量分数为a%，稀释时加入水的质量为n，稀释后溶质的质量分数为b%。则可得m×a%＝(m＋n)×b% （2）用稀溶液稀释浓溶液 设浓溶液的质量为A，其溶质的质量分数为a%，稀溶液的质量为B，其溶质的质量分数为b%，两溶液混合后所得溶液溶质的质量分数为c%。则可得A×a%＋B×b%=（A＋B）×c% （3）蒸发水进行浓缩 设浓缩前稀溶液的质量为m，其溶质的质量分数为a%，蒸发水的质量为n，浓缩后溶质的质量分数为b%。则可得m×a%＝(m-n)×b% 说明：如果采用加入溶质的方法使溶液中溶质的质量分数增大，那么可以根据：

Pre-reading Background reading: Scottish scientists at Roslyn Institute created the much-celebrated sheep "Dolly", aroused worldwide interest and concern because of its scientific and ethical implications. She was the first mammal to be cloned from adult DNA taken from an adult cell. Previously, animals had only been cloned using embryo(胚胎) cells which already have the potential to become a complete embryo in its own right. The big breakthrough with Dolly was to make a clone from an ordinary, adult cell ? in this case from a female goat’s udder. Questions: 1. How does Dolly differ from other sheep? She was ______________ by humans while the others were born naturally. So, Dolly was a ______________ sheep. 2. Should we clone a human? II. 【While-class 】 Step1. Lead-in Step2.
