    There are no exact differences between physics and other natural sciences because all sciences overlap(重叠）.In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects.
    One major branch of physics deals with the states of matter—solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane.
    A branch of mechanics is statics(静力学）,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism（磁力）,heat,light,and sound.From these branches of physics scientists find clues(线索） which have revealed(揭示） the constructions of atoms and how the atoms react to various kinds of energy. This knowledge is often called the basis of modern physics.Among the many subdivisions（细的分支）of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the “natural laws” of electricity to help in designing and electric generator(电动机）.

      There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external (外在的) result or a product that can easily be identified and measured. The worker who gets a rise, the student whose grades improve, and the foreigner who learns a new language—all these examples of people who have measurable results to show for their efforts.
    By contrast (对照), the process of personal growth is much more difficult to determine, since it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they meet with new experiences and unexpected difficulties. In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept.
    In order to grow, to travel new roads, people need to have a willingness to take risks, to face the unknown, and to accept the possibility that they may “fail” at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we see ourselves as quick and curious? If so, then we tend to take more changes and to be more open to unfamiliar experiences. Do we think we’re shy and indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe. Do we think we’re slow to adapt to change or that we’re not smart enough to deal with a new challenge? Then we are likely to take a more passive role or not try at all.
    These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to change and grow. If we do not face and overcome these internal fears and doubts, if we protect ourselves too much, then we stop growing. We become trapped inside a shell of our own making.
    小题1:In the author’s eyes, one who views personal growth as a process would __________.
    A．succeed in climbing up the social ladder
    B．judge his ability to grow from his own achievements
    C．face difficulties and take up challenges
    D．aim high and reach his goal each time
    小题2:Which of the following can be viewed as the process of personal growth?
    A．Our manager was always willing to accept new challenges.
    B．Little Tom won the first prize in the Speech Contest.
    C．Max picked up French while he was in Paris.
    D．Daddy’s salary rose from $3,000 to $3,800.
    小题3:The best title for this passage should be _________.
    A．Facing new challenges
    B．Growth ―product or process
    C．Unavoidable feeling of self-doubt
    D．Overcoming internal fears

    When 7-year-old Warren Buffett said,“I will be the richest man one day,” his friends made fun of his “daydreaming”. But ever since then the little boy has set about learning how to make money by selling drinks, delivering newspaper and buying stocks. The American had already earned $9,000 (equal to $90,000 today) by the time he graduated from high school.
    And this month the 78-year-old man, who earned his fortune by making a lot of sound investment in the stock market, took the place of Microsoft founder, Bill Gates, as the world’s richest man. Gates’ worth declined $1.5 billion to $55.5 billion in 33 days after the recent financial storm, according to Forbes Magazine.
    Buffett, the only son of a stockbroker, was ready to think outside the box to develop his business from a very early age. At 8, he went to golf courses collecting and selling the used balls. At 11 when he sold soda pop door-to-door with a friend, the pair collected lids on streets to judge which flavor was the most popular.
    As a paper boy during high school, Buffett delivered two competitor papers, so that even when customers canceled one of the subscriptions, he could still make a profit from the other. With his paper delivery savings, Buffett bought 162,000 square meters of farmland and collected rent. Young Buffett stepped into the stock market at 11 but earned only $5. The experience taught him one of the virtues in investing, patience.
    After graduating from university, Buffett started his venture with stocks with his childhood earnings and money from friends. He researched the stocks and just bought those of solid companies that were undervalued and inexpensive at the time. By sticking to companies such as American Express and Coca-Cola, Buffett has become rich.
    “Learning is important to Buffett’s success. He is a learning machine who can spend his entire day reading. He keeps learning from books, street smarts and investigation, from both success and failure. In this way, he over-achieved his aptitude (能力).” said Charlie Munger, his longtime business partner.
    小题1: The passage is mainly about ___________.
    A．why Buffett took the place of Bill Gates as the world’s richest man
    B．what effect Buffett’s childhood experiences had on his success
    C．how Buffett earned his fortune and achieved his aptitude
    D．what Buffett dreamt about when he was a child
    小题2: Which of the following is true about Buffett?
    A．His worth is more than $ 55.5 billion now.
    B．He is next to Bill Gates in wealth at the present time.
    C．He achieved great success on stepping into the stock market.
    D．He bought 162,000 square meters of farmland by selling soda pop.
    小题3: How did Buffett behave at the stock market?
    A．He often prefers some inexpensive stocks.
    B．He will buy the stock whose price is lower than its value.
    C．He always borrows money from his friends to buy stocks.
    D．He will sell the stock if its price doesn’t go up.
    小题4:Which is the main factor that determines Buffett’s success?
    A．His education.B．His family background.
    C．His desire to learn. D．His cooperation with his partner.
    小题5:What can we infer from the passage?
    A．Buffett is an immediate success in the stock market.
    B．Buffett and Gates are business partners.
    C．His father helped him a lot in his business.
    D．Buffett has a good sense of business.

    Here are five letters from readers listed in 1-5. All the greetings and signatures are left out. Suppose you are a secretary of the magazine CR (Crazy English Reader), for each one find a suitable reply from A-F. Mark the correct letter (A-F) on your answer sheet. There is one extra reply which you don’t need to use.
    1. I am a reader of CR. Recently I found students translate some articles of CR. I appreciate your offering an opportunity to us beginners to practise using English. So I want to ask how they can obtain these articles and translated them for you, and what qualities you require. Thank you.
    2. I love your Crazy English Reader magazine! It provides valuable data for work in our English teaching. My wife and I are teaching Conversational English so I’ve been giving you a bit of a plug at our middle school. I told the students to “get a copy!” It’s good stuff! Fantastic!
    3. I’m one of Yao’s fans from Guangzhou. I have read the Yao Ming articles in No.7 Crazy English Reader. I want to know his correspondence address and the official website. Could you please tell me? Thank you very much indeed.  
    4. First of all, I must say thank you very much to all the CE Reader editors who gave us a really good English magazine. Secondly, I want to give you a piece of advice. In each passage, you gave us some new words with their Chinese translation. However, as far as my knowledge, I think you should give us not only the Chinese meaning but also the English meaning so as to know the words more accurately. Thank you!
    5. I am an editor of the English Monthly of our school. I have a question that is how to say the position of the paper e.g., 总编责任编辑 and so on. I hope you can help me to tell me the word in English. The more the better. Thank you so much! I love the book very much. Now, I do this work, I need study more information about this work, if you have time, please email me. Thank you.
    Thank you for your suggestion. We may try that in some future issues of CR. I think the best way to improve your reading vocabulary is to be able to guess the meaning of the word from the other words around it. Also, if you have an English dictionary, it’s good to look up the words and then mark them down in a notebook and review them later on. Then if you really want to learn how to use the words, try using them in conversation or in writing. Hope this helps.
    The best way for you to learn the different positions in a newspaper or magazine is to get a copy of an all-English magazine or newspaper and then copy down the different positions. There are also titles such as Managing Editor, reporter, Copy Editor, Photo Editor and Layout Editor. I hope this helps. If you have some more specific questions, you can send them to me and I’ll try to answer.
    C．The best way to reach Yao directly is through his home team, the Shanghai Sharks. You can write him at 2570 Xietu Road, Shanghai. For more information on Yao, you can look at the sports section in sina. com. I hope this helps. Another idea is that you can try to write Yao while he’s living and playing in Houston. You can try to reach Yao in the US at:   Yao Ming   Compaq Centre 10  Houston, TX 77046
    Thank you for being such a careful reader of CR. Yes, you’re right we made a mistake in the writing of that Chinese word. Each issue we try to read very carefully each article and its translation to make sure there are no mistakes, but unfortunately a few mistakes always get by. But you encourage us to keep improving, so thank you.
    Yes, we do have several students who help us translate some of the articles in our magazine. We contact these translators directly after interviewing their translation work. Afterwards we assign the articles to them for translation. If you are interested in being one of our translators you can send us some information about yourself and a sample of your translation work.
    Thank you for helping us to promote CR. We’re glad it’s helpful to your students. We always try to include articles that reflect real life. It’s our hope that CR will not only improve student’s English but also open up a different worldview.

    注意：每个空格只填一个单词。
    The USA is the first country where Mother’s Day appeared.
    On May 9th, 1906,an American Anne Jevis’s mother died. Ann was in deep sorrow. In order to memorize her mother, she put forward a proposal to fix a day as Mother’s Day. On May 7th ,1914,the Congress of the USA passed a law ,making the second Sunday of May “Mother’s Day”.
    Today millions of Americans observe Mother’s Day in some ways. They buy more than 150,000,000Mother’s Day greeting cards. Companies produce more than 1,000 different kinds. Most of the cards show pictures of flowers, hearts or other things that people feel are linked to being a mother. They have messages that express a person’s love for his or her mother. Some are humorous. And some have no words. People can express their own feelings for their mother. Many people give flowers for Mother’s Day. It is one of the busiest days of the year for the flower industry. Many people have written songs about mothers and Mother’s Day.
    Mother’s Day is a time for young children to do special things for their mother. Some would make a special gift or draw a special picture. One family activity on Mother’s Day is to have the children cook the early morning meal .Then they serve the food to their mother while she is still in bed. Or they might clean the house so she does not have to do it. Fathers might take care of the children that day so the mothers can rest, or take a walk, or read a book. Many mothers feel that this free time on their special day is a very good Mother’s Day gift.
    Some families will get together for a meal at a local eating place. This means that mothers do not have to cook on their special day. Coming out to dinner has become a tradition on Mother’s Day. As a result, restaurants are extremely crowded that day. It has become one of the busiest days of the year for the restaurant industry in the United States.
    Now Mother’s Day has been an international festival and more than 40 countries have accepted this festival.

    Microsoft founder Bill Gates has recovered his spot at the top of the US money heap, taking the place of investor Warren Buffett as America's richest person, Forbes magazine's latest list reveals.

    With 57 billion dollars net worth Gates again leads the list of 400 richest individuals in the world's wealthiest country. He displaced Buffett who briefly held the position this year but who has seen his Berkshire Hathaway investment group's shares slip 15 percent since February and is now worth 50 billion.
    According to Forbes, whose list was published late Wednesday, the golden 400 have 1.3 billion dollars net worth or more. However, their combined net worth rose only 30 billion dollars, or two percent, to 1.57 trillion dollars.
    Forbes said that rising oil and dizzy art prices fuelled the entry of 31 new members into the ultra-rich club and the return of eight previous members.
    A notable arrival was Mark Zuckerberg, 24, founder of the social networking site Facebook（脸谱网）. Forbes estimates his worth at 1.5 billion dollars.
    Meanwhile, turmoil（动荡）on the stock and housing markets saw 33 others drop off the list, including the former head of the troubled insurance giant AIG, Maurice Greenberg, and a former head of the online auction site eBay, Margaret Whitman.
    Biggest gainers were led by New York Mayor Michael Bloomberg who took eighth place with 20 billion dollars worth after a transaction（交易）put a new value on his Bloomberg media and financial data network.
    The biggest loser was casino（赌场，娱乐场）tycoon Sheldon Adelson, whose fortune fell 13 billion dollars over 12 months -- the equivalent to 1.5 million dollars an hour -- although he still has 15 billion dollars and occupies 15th place.
    About two thirds of the list are self-made billionaires and just over 10 percent are women, led by television star Oprah Winfrey whose fortune rose 200 million dollars to 2.7 billion dollars.
    小题1: According to Forbes, Warren Buffet is worth _____.
    A．57 billion dollarsB．50 billion dollarsC．1.5 billion dollarsD．20 billion dollars

    A．tell the readers that television stars make money easily
    B．prove that a millionaire can become a billionaire
    C．women can also be billionaires

    A．one earns much and also loses much
