Several days ago,Yao twisted his ankle in the match VS Orlanto Magic.It really depressed me as the unending injuries had haunted the Rockets for the last whole season.I am so happy to know later that Yao is alright and will be healthy enough to face the challenges of new season.He is always performing like a gentleman no matter in the match or in daily life.I think he is a perfect delegate of China to the whole world.

翻译

今天有上级领导来学校检查，所以我们不得不做了很多事来迎接检查，但是做的这么多事情中有很多都不是我们平常做的或者根本就不能在平常做到。我觉得这样子迎接检查都是为了做面子，并不能反映学校正常的情况，而且还让学生花很多精力来做这些与学习无关的事情，是没有一点意义的。

谢谢

1. Introductory Paragraph The first sentence should state for which instructor and class the book-report is being written.The second sentence should state the title of the book and the author's name. The third sentence should tell how many pages the book has and the name of the publisher. The fourth sentence can state basic bibliographic information about the book. Bibliographic information means not only the author and title but also what company published the book, what year it was published in and any other relevant information such as the edition and if the book has been translated, simplified or abridged. (see copyright page and the back of the title page.) The next sentence should state the reason(s) you decided to read this book. Why did you choose this particular book? Typical reasons might be:o You like the author. o You like this type of book (i.e. mystery, western, adventure or romance, etc.). o Someone recommended the book to you. o It was on a required reading list. o You liked the cover. These reasons do not have to be complex. Most people choose the books they read because they like the author or somebody recommended it to them. If you chose the book because you like the author, then state why you like that author. An optional sentence can be used if the cover (back cover) of the book gives you any additional information then add a sentence with that information.o Was the book a best seller? o Are there X million copies in print? o Did it win any major awards? 2. Main Character(s) Paragraph The first sentence of this paragraph should state who the main character or characters of the book are, and why they are important. Refer to this person or these persons as the Main Character or Main Characters. You will need at least a complex sentence for this, and probably more than one sentence. 3. Other Characters Paragraph You should compose at least one sentence for each of the other prominent or important characters in the book. State the name of each of the other important characters, and the key role that each one plays in the book Most books have five or six prominent characters besides the main character, so simply listing each one and stating their role in the book will give you a good sized paragraph. 4. Plot Summary Paragraph This is perhaps the hardest paragraph to write in five sentences or so. If you have to write a bit more don't worry. Here are the main points to cover: o State the type of book (Mystery, Western, etc.). o What place or country was the book set in? o What time period was the book set in? (19th century, the present, ancient Rome, the 23rd century). o Other physical locations which are important, like: ships, airplanes, houses, or buildings. o Other notable attributes of the book. (Was it violent, scary, fast paced, etc.). o What is the main character trying to do? o What is the outcome of the book? o etc. Make sure you cover all of the major parts of the plot. You might have to go back through the book, chapter by chapter, and make a few notes. 5. Personal Impressions and Conclusion Paragraph Simply talk about what you liked or did not like about the book. Use this paragraph as your conclusion. It should summarize your overall impressions of the book and bring the report to a close. o Start with a sentence that states that you are now writing a conclusion. (For example: "My final thoughts on 'A Fine Balance' are that it is a fascinating book but I am not entirely sure if I completely understood the thematic message of the book." o Restate your reasons why you liked and/or disliked the book using different words. o Write two sentences that talk about the books good points and weak points. o Write a sentence or two about what you learned from the book. o Close with a sentence that states whether you would recommend the book to others. Don't be afraid to give your own honest impressions of the book. After all, if you've read the book thoroughly, you are entitled to your own interpretation of it. Typically, your book report should not exceed two double-spaced pages, and it should be somewhere between 600 and 800 words in length. Research Assistance This site, which claims to be the best single research source online, maintains an inventory of more than 25,000 research reports on thousands of subjects; many of which are book summaries.

一、感谢信 Sample 120 June 2006 Dear Mr. Seaton,Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen the Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn't have known my way about.The weather was splendid on that day, which I thought was rare. I still remember some people told me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. So I think I was lucky.I think the river trip was the best thing of all. London really came alive for me as we saw it from the Thames during that wonderful journey down to Greenwich. It was all tremendously exciting - a day that I shall never forget.Thank you for giving me such a great birthday treat.Yours sincerely, Linda Chen Sample 220 July 2006 Dear Mr. Wang,Thank you for taking the time to write your wonderful letter in support of MCEA (Maywood Chinese Education Association). Your letter clearly articulates all the major reasons children in Maywood will benefit from studying the Chinese language as part of their elementary school education. It provides invaluable support that will help making bilingual Chinese education a reality in Maywood public schools.Although MCEA would like to see Palo Alto public schools implement the first bilingual Chinese kindergarten class in September of 2006, we have learned that the school district must take the time to understand how a new program will affect existing educational offerings, and to validate community interest. Nevertheless, MCEA, with more than 70 members, will continue to actively promote bilingual Chinese education in the Palo Alto public schools and will keep you apprised of the progress we make.Thanks again for sending a letter in support of MCEA. We' will continue to do all we can to realize this program both for families of Chinese descent and those with a general interest in participating in the growing economic power of China.Yours sincerely,George Chen Useful Expressions Thanks for. . . It was very nice/good of you to 。

Thank you very much for. . . I must thank you for. . . I am extremely grateful for your help. . . I am most grateful for. . .二、建议信 Sample 121 June 2006 Dear Mary,Thanks for your last letter. I'm so glad that you have been able (at last! ) to arrange a holiday in Australia. As I fear I won't be able to meet you at the airport when you arrive, nor will I be able to be home until later in the afternoon, so here are some instructions and suggestions.There is a bus from the airport to the city. It is much cheaper than a cab. Take the bus to the city and ask to get off at Town Hall railway station.To get to my place in the eastern suburbs you have three options. You can either take a cab, a bus or the train. I suggest you take the train, since the airport bus will leave you right at the station. Get off at Cliff Station. From there you can either walk to my place (about ten minutes) or take a taxi. Probably you should take a taxi as you will have luggage. When you arrive at my flat, ring the intercom for Flat 2. My friend Lillian will be at home and she will open the front door for you and let you into my flat.Presumably you will be tired and want to sleep. But if you feel like some exercise after that long flight, you could stroll down to Cooper Park, which is only ten minutes away ? you can see it from the window.Cheers and looking forward to seeing you.Yours sincerely, Annie P.S. I will leave something for breakfast in the fridge. Help yourself to anything you want.Useful Expressions: Here are some instructions and suggestions. May I suggest that we meet at the gate of the university? I'd like to suggest you should visit London for at least two days on your way to Scotland. Considering your present situation, I propose that you should apply for the post. What I want to suggest is 。 My suggestion is that. . .

Since leaving university I have been working in a research laboratory but my contract comes to an end in six weeks. I would particularly like to join the expedition for the opportunity it would give me to study the plant life of the area.I enjoy several outdoor activities including rowing and rock climbing and I consider myself to be both fit and healthy enough to undertake 。

6.关于写英文信的格式

英文书信的格式 英文书信是一种最常用的应用文体，对于普通的私人信件通常由五部分组成： 1.信头：指发信人的地址和日期。

写在信纸的右上角，可以从靠近信纸的中央写起。信头上面要留空白。

先写发信人地址。地址的写法与汉语不同，要先写小地方，后写大地方。

在地址的下面写上日期。日期的顺序是：月、日、年，或者：日、月、年。

例如：May 17? 2003。在年份之前有一个逗号。

2.称呼：指对收信人的称呼。写在信头之下，从信纸的左边开始。

写信给熟悉的人，一般用Dear…或My dear…作称呼。如：Dear Li Lei,Dear Miss Thomas或My dear Dad. 3.信的正文：指信的主体部分。

从称呼的下一行第一段顶边写。从第二段起每段第一个词都缩进3或5个字母写。

4.结束语：指正文下面的结尾客套话。一般从信纸的中央靠右写起，第一个字母大写，末尾用一逗号。

在非正式的社交信中，常用Yours或Sincerely。假如对方是亲密的朋友，可用Sincerely yours?Yours等。

5.签名：指发信人签名。写在结束语的下面，稍偏右。

另外，英文信封写法与汉语的不同。一般把收信人的地址写在信封的中央或偏右下角。

第一行写姓名，下面写地址。发信人的姓名和地址写在信封的左上角，也可以写在信的背面。

英文书信的格式 1、信头（Heading） 指发信人的姓名（单位名称）、地址和日期，一般写在信纸的右上角。一般公函或商业信函的信纸上都印有单位或公司的名称、地址、电话号码等，因此就只需在信头下面的右边写上写信日期就可以了。

英文地址的写法与中文完全不同，地址的名称按从小到大的顺序：第一行写门牌号码和街名；第二行写县、市、省、州、邮编、国名；然后再写日期。标点符号一般在每一行的末尾都不用，但在每一行的之间，该用的还要用，例如在写日期的时候。

2、日期的写法： 如：1997年7月30日，英文为：July 30,1997（最为普遍）； July 30th,1997; 30th July,1997等。1997不可写成97。

3、信内地址（Inside Address）： 在一般的社交信中，信内收信人的地址通常省略，但是在公务信函中不能。将收信人的姓名、地址等写在信头日期下方的左角上，要求与对信头的要求一样，不必再写日期。

4、称呼（Salutation）： 是写信人对收信人的称呼用语。位置在信内地址下方一、二行的地方，从该行的顶格写起，在称呼后面一般用逗号（英国式），也可以用冒号（美国式）。

（1）写给亲人、亲戚和关系密切的朋友时，用Dear或My dear再加上表示亲属关系的称呼或直称其名（这里指名字，不是姓氏）。例如：My dear father,Dear Tom等。

（2）写给公务上的信函用Dear Madam,Dear Sir或Gentleman(Gentlemen)。注意：Dear纯属公务上往来的客气形式。

Gentlemen总是以复数形式出现，前不加Dear，是Dear Sir的复数形式。 （3）写给收信人的信，也可用头衔、职位、职称、学位等再加姓氏或姓氏和名字。

例如：Dear Prof. Tim Scales, Dear Dr.John Smith。 5、正文（Body of the Letter）： 位置在下面称呼语隔一行，是信的核心部分。

因此要求正文层次分明、简单易懂。和中文信不 同的是，正文中一般不用Hello！（你好！）正文有缩进式和齐头式两种。

每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。

商务信件大都采用齐头式的写法。 6、结束语（Complimentary Close）： 在正文下面的一、二行处，从信纸的中间偏右处开始，第一个词开头要大写，句末用逗号。

不同的对象，结束语的写法也不同。 （1）写给家人、亲戚，用Your loving grandfather,Lovingly yours,Lovingly等； （2）写给熟人、朋友，用Yours cordially,Yours affectionately等； （3）写业务信函用Truely yours(Yours truely),Faithfully yours(Yours faithfully)等； （4）对上级、长辈用Yours obediently(Obediently yours),Yours respectfully(Respectfully yours)等。

7、签名（Signature） ： 低于结束语一至二行，从信纸中间偏右的地方开始，在结束语的正下方，在签完名字的下面还要有用打字机打出的名字，以便识别。职务、职称可打在名字的下面。

当然，写给亲朋好友的信，就不必再打了。 8、附言（Postscript） ： 一封信写完了，突然又想起遗漏的事情，这时用P.S.表示，再写上遗漏的话即可，要长话短说。

通常在信末签名下面几行的左方，应于正文齐头。 注意：在正式的信函中，应避免使用附言。

9、附件（Enclosure） ： 信件如果有附件，可在信纸的左下角，注上Encl：或Enc： 例如：Encl:2 photos（内附两张照片）。如果福建附件不止一项，应写成Encl：或Encs。

我们有时可看到在称呼与正文之间有Re：或Subject：（事由）字样。一般在信纸的中间，也可与“称呼”对齐。

还应在底下加横线，以引起读信人的注意，使收信人便于在读信之前就可了解信中的主要内容。事由一般在公务信函中使用，也可以省略。
