A
President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket．
"I just miss - I miss being anonymous (无名的)," he said "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk".
His dream, he said, was to "go through Central Park and watch folks passing by---spend the day watching people --- I miss that".
Faced with angry criticism for playing more golf than most previous presidents of the White House, he explained that the sport was simply the best way of getting away from the pressure. "It's the only excuse I have to get outside for four hours." he told Hearst magazines.
Though he said he enjoyed his life in the White House, he felt disappointed with some of the ways of Washington, which he has failed to change, such as the "kabuki dance"(日本歌舞)among political parties before serious policy discussions begin. His comments may be seen as evidence by critics who have accused him of appearing too indifferent（漠然）, and being slow to engage in important issues such as Libya and the near shutdown of the US government last week.
Since arriving at the White House in January 2009, Mr. Obama has already racked up 60 rounds of golf in office, more than George W Bush did in his eight years. In terms of ability, Golf Digest magazine has ranked Mr. Obama eighth out of the 18 presidents who played the game since it became established in the early 20th century.
56. What do the second paragraph and the third paragraph mainly tell us?
A. Obama wishes to enjoy simple pleasures.
B. Obama used to spend most of his time with his family.
C. Obama likes living a busy life.
D. He used to wash his car himself.

D. content with
59. Which of the following statements is from the critics?
A. The president lost lots of privacy, but he loves the life in the White House
B. There are always unnecessary procedures among political parties.
C. The president seems to be indifferent towards some really important issues.
D. The president is really a great golf player.
60. What is the passage mainly about?
A. Obama's favorite pastime.
B. Obama’s regrets for being the U.S. president.
C. The public's criticism of Obama.

Sundance Film Festival
The Sundance Film Festival is held in January of each year in Park City, Utah. This exciting festival is the biggest of its kind in the U.S. It focuses on independent films and it is a platform for new up-and-coming directors to show their creations. The Sundance Festival includes many different categories, from documentary to dramatic, and domestic to international. Both short and full-length pictures are now allowed.
Academy Awards
The Academy Awards ceremony has come a long way from its 1929 beginning as a small, private ceremony to its present-day status as the red carpet event of the year. While the Oscar is the Academy’s best known award, it is not the only one awarded by the Academy. In fact, the Academy’s Board of Governors also gives out Science and Technical Awards, Honorary Awards and Special Achievement Awards.
Cannes International Film Festival
The Cannes International Film Festival is held in Cannes, France. It is an annual event which nowadays takes place during May. The concept of the festival dates back to 1932. Some French film-makers demanded that the French government support a film festival where films could be judged on merit(价值), rather than in a political context. The choice of venue was between Biarritz and Cannes, and the latter was chosen because it was the only place willing to fund the festival.
Berlin International Film Festival
One of the most awaited film festivals of the year is the Berlin International Film Festival. It has been held annually since 1951 every February. This is where the best and the brightest of the stars from across the globe gather to witness a grand ceremony of films.

C
Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there is no need for a lot of scientific terms or expensive lab equipment. You only have to s hare your children’s curiosity. Firstly, listen to their questions. I once visi ted a classroom of seven–year-olds to talk about science as a job. The children asked me ―textbook questions‖ about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in science. Finally I said,‖ Now that we’ve finished with your lists, do you have questions of your own about science?‖
After a long pause, a boy raised his hand, ―have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?‖
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that. After asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their ―wait time‖ to three seconds or more, children give more logical, complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science dis cussion, don’t jump in with ―That’s right‖ or ―very good‖. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, ―That’s interesting‖ or ―I’d never thought of it that way before‖, or coming up with more questions or ideas.
Never push a child to ―think‖. It doesn’t make sense; children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a small target for your disagreement.
Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass, and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
66. According to the passage, children are natural scientist, and to raise their interest, the most important thing for adults to do is______.
A. to share the children’s curiosity
B. to let them see the world around
C. to explain difficult phrases about science
D. to supply the children with lab equipment
67. In the last sentence of the first paragraph, the word ―list‖ could best be replaced by______.
A. any problems
B. questions from the textbooks
C. any questions
D. any number of questions
68. According to the passage, children can answer questions in a more logical, complete and creative way if adults______.
A. ask them to answer quickly
B. wait for one or two seconds after a question
C. wait at least for three seconds after a question
D. tell them to answer the next day
69. In which of the following paragraph (s) does the author tell us what to say to encourage children in a science discussion?
A. The second and third
B. The fifth
C. The fifth and sixth
D. The fourth and fifth
70. The author mentions all of the following techniques for adults to share with their children’s curiosity EXCEPT that adults should______.
A. encourage their children to ask questions of their own
B. offer their children chances to see things for themselves
C. be patient enough when their children answer questions
D. tell their children stories instead of reciting (背诵) facts

Guitars have always defined the sound of the blues. Blues music came into being in the 1890s and became mature in 1910. At first, it was powerful songs accompanied by the acoustic guitar(原声吉他), sung by slaves and poor white people to express their sorrow. In 1925, the style was given the name“the blues”.
The blues has a deep history, with different blues guitarists contributing their own style.
Born in 1911, Robert Johnson was one of the earliest blues guitarists whose music still makes an impact today. Performing only for a short time, Johnson contributed a lot to the blues tradition and was the first one to start the slide guitar technique(演奏手法) with the blues guitar. His songs are very popular and can be used to learn the correct way to play the blues guitar.
The second-greatest blues guitarist is B.B. King. Being a great guitarist, B.B. King had a crisp guitar style, which is perfect for beginners to start with. He had developed his own style, including various blues traditions such as the slide guitar.
Another famous blues guitarist is Eric Clapton. He became famous during the revolution in the British blues music scene in the 1960s. Clapton used heavy slide guitar techniques to develop his own style, which was quite close to rock. His songs have inspired and influenced many blues guitarists.
Blues guitarist, Stevie Ray Vaughan, is also well-known. His guitar style became popular because it included some elements of the jazz guitar and the heavy use of vibrato(颤音). Today, with the blues style being so popular, many people are trying to learn and become blues guitarists. As beginners, to become a blue guitarist, you should study the famous musicians. Listen to their music and watch their videos. Study the work of the blues guitarists and try to learn about specific playing styles.

Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit. Write your answers on your answer sheet.
Jane Eyre, by Charlotte Bronte, is the story of a young w oman’s struggle to find happiness. As a child, Jane is sent to live with her aunt and uncle after her parents die. Her aunt and cousins are very cruel to her. Then, Jane is sent to Lowood, a school for poor children. Here, she experiences more cruelty. The students do not get enough food to eat and they have to wear old, ugly clothes. At Lowood, Jane makes a good friend, Helen Burns, who is very kind and patient. She believes that it is better to do without the things you want. Even though Jane loves Helen, she cannot agree with her. Jane believes that both rich and powerful people and poor people deserve the same treatment.
Jane leaves Lowood years later and becomes the private teacher of the daughter of Mr. Rochester, who is a very rich man. Jane is still not completely satisfied with her life because she realizes that women do not have the freedom to choose what they want to do—she has become a teacher because she has no other choice.
Jane and Mr. Rochester fall in love and make arrangements to get married. However, on the day of the wedding, Jane is disturbed to learn that Mr. Rochester is already married. His wife is mad and is locked in the attic. Mr. Rochester says that he still wants to marry her. Even though Jane loves him, she knows that it would not be a good idea to stay with him. So, she makes the difficult decision to leave him.
Jane meets St John Rivers and his sisters, and stays with them. Jane finally has the loving family that she has always wanted. After some time, St John proposes to Jane. As Jane does not truly love him, she refuses him even though he is a good man. Jane goes back to Mr. Rochester to find out that his wife has died and they are free to get married. By following what she believes is right, Jane finds happiness in the end.

数系的扩充与复数的概念 编稿张富全 1、教学目标： （1）经历数的概念的发展和数系扩充的过程，体会数学发现和创造的过程，以及数 学发生、发展的客观需求； （2）理解复数的基本概念以及复数相等的充要条件； 2、教学重点、难点： （1）重点：体会数的概念的发展和数系扩充的过程，从中感受实际需求与数学内部的矛盾在数系扩充过程中的作用，并认识数系扩充的原则； （2）难点：认识到实数系向复数系扩充的必要性，并掌握如何将实数系扩充到复数系，从而掌握复数的相关概念。 3、教学方法与教学手段： 创设情境、启发引导 4、教学过程设计： 一、人类对数的认识过程的回顾 先回顾数的发展史（到实数为止），即教材中的“为了计数的需要产生了自然数，为了测量等需要产生了分数，不了刻画具有相反意义的量产生了负数，为了解决度量正方形对角线的长的问题产生了无理数，等等”。 紧接着介绍数学史上16世纪意大利数学家卡尔丹在其著作《大术》一书中提出的这样一个问题“将10分为两部分，使得两部分之积为40”。他将其中一部分设为x,另一部分则为10-x，于是得到方程x(10-x)=40， 请学生解一下这个方程（学生：无解）。为什么无解？（△<0） 问题1：什么叫方程无解？ 回顾关于方程解的问题： 方程x+1=0,对于一个不知道负数的小学生而言有解吗？ 方程2x=3，对于一个不知道分数的小学生而言有解吗？ 方程x2=2,对于一个不知道无理数的初一学生而言有解吗？ 问题2:方程是否有解与什么相关? （通过上述问题的研究,让学生感受方程是否有解与人的认识程度有关,同时
与数集有关。随着人的认识程度的深入以及数集的扩充，在原来数集中无解的方程到了新的数集中也可以变得有解。） 方程x(10-x)=40是在什么范围类无解?(实数集) 问题3：有没有必要将实数集扩充，使得此类方程在新的数集中变得有解？ 再回到数学史，1572年意大利工程师邦贝利(Rafael Bombelli)的著作《代数学》一书中，邦贝利研究卡尔丹《大术》中另一个方程x 3-15x-4=0的时，利用一元三次方程求根公式求得了它的两个根32± -，而另外一个根写成了这样的形式：3312121212--+-+，邦贝利同时发现，这个三次方程显然有一个解 x=4，这说明应该有41112111233=--+-+，由此说明负数开平方应 该得到承认，实数集有必要扩充！ 问题4：怎样将实数集进行扩充，使得x 2=-1之类方程在新的数集中有解呢？ 点明课题 问题5：怎样进行数系的扩充？ (通过上述过程是为了让学生体验到人类的认识过程是一个从简单到复杂、从低级到高级的过程，数的发展是为了满足人们生产生活的需要，也是为了解决因研究探索而形成的认知冲突。在数学文化背景下设计的问题串，是为了让学生充分地感受到实数集扩充的必要性，并感受在面对用理性思维进行研究探索而形成的认知冲突时，要有科学精神，要以理性精神、发展的观点认识新问题，发展新观念。) 二、实数系向复数系扩充 问题6：按照数集扩充的原则，对实数集进行扩充，并要使得方程x 2=-1有解，至少 应该在新数集中添加怎样的一个数？ 问题7：有了i ，新的数集中还会有什么数？ 问题8：这些数有什么一般形式？ 在归纳前有的数系扩充过程的基础上，实现实数系向复数系的扩充，进而掌握复数的概念以及相关的一些概念（如虚数单位、复数的实部与虚部、复数集）。 （同样在问题串的带领下，在有理数集向实数集扩充过程的铺垫下，让学生

第I卷（选择题） 请点击修改第I卷的文字说明 一、选择题（题型注释） 50 mL 0.5 mol·L－1盐酸与50 mL 0.55 mol·L－1 NaOH溶液在如图所示的装置中进行中和反应。通过测定反应过程中放出的热量计算中和热。下列说法正确的是 A．实验过程中没有热量损失 B．图中实验装置缺少环形玻璃搅拌棒 C．烧杯间填满碎泡沫塑料的作用是固定小烧杯 D．酸或碱的物质的量越大，所测中和热的数值越大 【答案】B 【解析】 试题解析：该装置虽然采取了一定的保温措施，但不可能完全杜绝热量的散失，故A错误；该实验装置缺少环形玻璃搅拌棒，故B正确；烧杯间填满碎纸条的作用是保温，减少热量的散失，故C错误；中和热指稀溶液中强酸和强碱反应生成1mol水所释放的热量，与反应物用量无关，故D错误。 考点：中和热的测定 2．对处于化学平衡的体系，由化学平衡与化学反应速率的关系可知 A．化学反应速率变化时，化学平衡一定发生移动 B．化学平衡发生移动时，化学反应速率一定变化 C．正反应进行的程度大，正反应速率一定大 D．只有在催化剂存在条件下，才会发生化学反应速率变化而化学平衡不移动的情况 【答案】B 【解析】 试题解析：正逆反应速率都变化但仍相等，则平衡不移动，故A错误；反应向正反应方向进行时，说明正反应速率大于逆反应速率，但正反应速率不一定增大，也可能减小，此时逆反应速率更小，故C错误；化学平衡发生移动时，正逆反应速率不等，一定发生变化，故B 正确；如反应前后气体的体积不变，增大压强，平衡也不移动，故D错误。 考点：化学平衡与反应速率 3．下列各组物质的燃烧热相等的是 A．碳和一氧化碳B．淀粉和纤维素 C．1 mol碳和3 mol碳D．3 mol C2H2和1 mol C6H6
