One afternoon, many years ago, I went to pick up my mother from work. I got there a little early so I 31 the car by the roadside and waited for her.
As I looked 32 the car window, there was a small park where I saw a little boy, around two years old, 33 freely on the grass as his mother watched from a short 34 . The boy had a big smile on his face 35 he had just been set free from some sort of 36 . The boy would then fall to the grass, 37 , and without hesitation or without looking back at his mother, run as fast as he could again, still with a 38 on his face.
Kids, when they fall down, don't view their falling down as failure, but 39 , they treat it as a learning experience. They try and try again until they 40 . While I was touched by the boy's persistence, I was 41 touched by the manner in which he ran. With each attempt, he looked so 42 and so natural — no signs of fear, nervousness, or of being discouraged. His only 43 was to run freely and to do it as effectively as he could. He was just being a 44 — just being himself—being completely in the moment. He was not looking for 45 or was not worrying about whether 46 was watching. He didn't seem to be bothered by the fact that maybe someone would see him 47 and that it would be 48 if he did fall. No, all that 49 to him was to accomplish the task, to feel the experience of running fully and freely. I learned a lot from that 50 and experience, and have successfully brought that lesson with me in my many pursuits(追求) in life.

第三部分 阅读理解(共两节,20小题;每小题2分,满分40分)
阅读短文(共15小题;每小题2分,满分30分)
阅读下列短文,从各题所给的A、B、C、D四个选项中,选出最佳选项,并在答题卡上将该项涂黑。
A
As you grow older, you’ll be faced with some challenging decisions—like whether to cut class or try cigarettes. Making decisions on your own is hard enough, but when other people get involved and try to pressure you one way or another it can be even harder. People who are your age, like your classmates, are called peers. When they try to influence how you act, to get you to do something, it’s called peer pressure.
Peers can have a positive influence on each other. Maybe another student in your science class taught you an easy way to remember the planets in the solar system. Maybe you got others excited about your new favorite book, and now everyone’s reading it. These are examples of how peers positively influence each other.
Sometimes peers influence each other in negative ways. For example, a few kids in school might try to get you to cut class with them; your soccer friend might try to convince you to be mean to another player and never pass him the ball.
It is tough to be the only one who says “no” to peer pressure, but you can do it. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do.
You’ve probably had a parent or teacher advising you to “choose your friends wisely.” Peer pressure is a big reason why they say this. If you choose friends who don’t cut class, smoke cigarettes, or lie to their parents, then you probably won’t do these things either, even if other kids do.
If you continue to face peer pressure and you’re finding it difficult to handle, talk to someone you trust. Don’t feel guilty if you’ve made a mistake or two.

C. Choosing friends with no bad habits.
D. Helping others who are in trouble.
54. What is the topic of the passage?
A. Friendship. B. Making decisions C. Self-confidence D. Peer pressure

From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.
The international space station (ISS) is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.
As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone,and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone’s effort and will benefit everyone.
Led by the U.S. and Russia, the ISS is a joint project between six space agencies involving 16 countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten-year’s hard work in construction. China has applied for participation in (taking part in) the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ-F/T1 carrier rocket blasted off (leave the ground) and successfully carried the Tiangong-1 into space on September 29, 2011, China takes a big step toward its Space Station Era.
Some West media suggested that the successful launch of Tiangong-1 would disturb the balance of global space power, raising concerns (关注) about “China threat”. China’s space project is not designed for military (军事的) purpose but for developing space technology to explore space resources and make use of them for mankind’s well-being.
55. From Paragraph 2 we learn that ________.
A. the necessity of building the international space station is not realized now
B. many experiments have been done in the international space station
C. the international space station is necessary for people to explore space more
D. people have traveled to Mars from the international space station
56. Which of the following is NOT a reason for countries’ cooperation in building the international space station?
A. That it requires a lot of money. B. That it needs everyone’s effort.
C. That it will benefit every participating country. D. That it is too far away from the earth.
57.The underlined word “aggregated” in Paragraph 3 can be replaced by “________”.
A. united B. scolded C. allowed D. forbade
58. China wants to build its space station in order to __________.
A. break the balance of global space power
B. show that China can build space station alone
C. raise international concerns about “China threat”
D. make use of space peacefully for mankind’s well-being
C
An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same town.
In addition to encouraging reading as a pursuit to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.
In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.
As Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
59. What is the purpose of the project launched by Nancy?
A. To invite authors to guide readers. B. To encourage people to read and share.
C. To involve people in community service. D. To promote the friendship between cities.
60. According to the passage, where would the project be more easily carried out?
A. In large communities with little sense of unity
B. In large cities where libraries are far from home
C. In medium-sized cities with a diverse population
D. In large towns where agreement can be quickly reached
61. The underlined words “shared a word” in Paragraph 5 probably mean .
A. exchanged ideas with each other
B. discussed the meaning of a word
C. gained life experience
D. used the same language
62. According to Nancy, the degree of success of the project is judged by .
A. the careful selection of a proper book
B. the growing popularity of the writers
C. the number of people who benefit from reading
D. the number of books that each person reads
D
The Internet will open up new vistas (前景), create the global village -- you can make new friends all around the world. That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationship with more than a limited number of people. No matter how hard the Internet tries to put you in communication, its best efforts will be defeated by your mind.
The problem is twofold(双重的). First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest (投入)in them. We invest a lot in a small number of people and then distribute what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline until eventually it dies into “someone I once knew”.
This is not, of course, to say that the Internet doesn’t serve a socially valuable fun_ction. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see them, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The Internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.
63. What is stressed in the first paragraph?
A. The present situation of the Internet.
B. The difficulty in communication on the Internet.
C. The socially valuable fun_ction of the Internet.
D. The role of the human mind in the Internet communication.
64. The underlined word “engagement” in the second paragraph probably means “__________”.
A. appointment B. connection C. interview D. agreement
65. According to the passage, the author holds the view that _________ .
A. the Internet fails to play so valuable a role in communication as it promised
B. the Internet determines the quality of social relationships
C. the Internet greatly increases the size of social circles
D. the Internet communication is no less effective than the face-to-face talk

Five Happiness Secrets For Tough Times
Sonja Lyubomirsky, an author, has researched the science of happiness for years.
Here are her tips to help you cope with a bad economy, and increase your bursts of happiness throughout the day.
66.________
“You could spend a lot of time thinking deeply,” says Lyubomirsky.“But that just makes you feel even more pessimistic, more out of control, and affects your self esteem.Your relationships will suffer and your job performance will suffer.”
Get rid of pessimism.One of the most effective ways to cope when things are difficult is to adopt a positive thinking strategy.“What can I learn from this? Times are tough, I’ve been furloughed at work, but I can spend more time with the kids, adopt a new hobby, or learn a new set of skills.”
67.________
Now more than ever we need each other to survive.Lyubomirsky found that doing good things for friends, family, or strangers can make you happier.Think of practical, everyday gestures that can make someone’s life a little bit easier.For example, Lyubomirsky says, “Maybe now many of us can’t afford to take a cab to the airport, so offer to give a friend a ride.”
68.________
You don’t need an expert to tell you that relationships are critical to happiness.
Not being the bread-winner anymore or not being able to fulfill your kid’s needs can weigh down hard on your family life.But the trick is to stop feeling guilty and focus on caring for your loved ones.
“I was at a psychology conference where an expert was talking about the effects of this economy on families and how parents can’t afford to buy their kids luxuries like toys anymore,” says Lyubomirsky.“But what they don’t realize is that kids don’t care about toys — what they care about is parents being grumpy and taking it out on them.”
69.________
“If you find a happy person you will find a project,” says Lyubomirsky.“Happy people all have goals they care about.”
Commit yourself to a project – whether it is a business you want to start or a dance you want to learn.But it’s also important to remember to be flexible in these times.
Don’t get frustrated if circumstances are stopping you from meeting your goals.Adopt and change!
“If your spouse has lost their job you might have to change your goal,” says Lyubomirsky.“Or you might have to learn a whole new skill for a new job.”
70.________
When times are tough, it’s easy to get skip your regular workouts in favor of moping in front of the TV and eating a bag of chips.Your thinking is “I have more important things to worry about right now than looking good.”
But carve out a small part of your day to give your body some TLC.It will go a long way in boosting your happiness.“Even if you can’t afford to go to the gym,”
Lyubomirsky says, “take time out to exercise at home.”
A.Focus on your relationships.
B.Think about what to do next step.
C.Take good care of your body.
D.Try to avoid over thinking.
E.Set up a proper goal for yourself.
F.Practice acts of kindness.

阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词(注意:每个空格只填一个单词)
There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy, the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.
People who are to be happy fix their attention on the convenience of things. The pleasant parts of conversation, the well prepared dishes, the goodness of the wine, the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
Though in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrong doings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

One possible version:
Dear Sir or Madam:
Li hua, a senior student of Xin Hua High School. Recently some primary schools in Xi’an made pupils whose schoolwork and general behavior were good enough wear red scarves of the Chinese Young Pioneer while those not good enough wear green ones, saying this was aimed at encouraging the pupils who did badly in school to make progress.
Personally I think the measure taken by those schools divides the children into two different groups. It’s discrimination against those so-called problem students and could even harm their self-respect. Schools should immediately stop this inappropriate measure. Instead, they should try to give them more help and encouragement to enable them to do better.
All the best!
Yours,
LiHua
