When I come across a good article in reading newspaper, I often want to cut and keep it. But just as I am about to do so, I find the article on the 36 side is as much interesting. It may be a discussion of the way to 37 in good health, or 38 about how to behave and conduct oneself in society. If I cut the front article, the opposite one is likely to 39 damage, leaving out half of it or keeping the text 40 the title. Therefore, the scissors(剪刀) would 41 before they start, 42 halfway done when I find out the 43 . Sometimes two things are to be done at the same time, both worth your 44 . You can only take up one of them, the other has to wait or be 45 up. But you know the future is unpredictable(无法预料) --the changed situation may not allow you to do what is left 46 . Thus you are 47 in a difficult position and feel sad. How 48 that nice changes and brilliant ideas should gather around all at once? It may happen that your life 49 greatly on your preference of one choice to the other. In fact that is what 50 is like: we are often 51 with the opposite sides of a thing which are both desirable like a newspaper cutting. It often occurs that our attention is drawn to one thing only 52 we get into another. The 53 may be more important than the latter and give rise to a divided mind. I 54 remember a philosopher's remarks: "When one door shuts, another opens in life." So a casual(不经意的) 55 may not be a bad one.

Ⅳ．阅读理解(共20小题，每小题2分，满分40分)
A
Parents often believe that they have a good relationship with their teenagers(青少年). But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. "The door to his room is always shut." Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. "She used to cuddle up (蜷伏)with me on the sofa and talk," said Mark. "Now we joke that she does this only when she wants something, Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which."
Before age 11, children like to tell their parents what's on their minds. "In fact, parents are first on the list." said Michael Riera, author of Uncommon Sense for Parents with Teenagers. "This completely changes during the teen years." Riera explained. "They talk to their friends first, then maybe their teachers, and their parents last."
Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
56. "The door to his room is always shut" suggests that the son ______.
A. is always busy with his studies
B. doesn't want to be disturbed
C. keeps himself away from his parents
D. begins to dislike his parents
57. What troubles Tina and Mark most is that ______.
A. their daughter isn't as lovely as before
B. they can't read their daughter's mind exactly
C. they don't know what to say to their daughter
D. their daughter talks with them only when she needs help
58. Which of the following best explains "the wall of silence" in the last paragraph?
A. Teenagers talk a lot with their friends.
B. Teenagers do not want to understand their parents.
C. Teenagers do not talk much with their parents.
D. Teenagers talk little about their own lives.
59. What can be learned from the passage?
A. Parents are unhappy with their growing children.
B. Parents have suitable ways to talk with their teenagers.
C. Parents should be patient with their silent teenagers.
D. Parents should try to understand their teenagers.

第三部分：阅读理解
请认真阅读下列短文，从短文后各题所给的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
I was raised on a farm in the Fraser Valley along with five sisters and one brother. When I was 15, I got addicted to drinking at weekends and then dropped out of school. By the time I was 17, I continued to drink heavily. I couldn't find a job to support myself. So, I had no other choice but to join the army. I retired and went back home three years later, still a heavy drinker. When I was 22, I met Sue whose father was also a heavy drinker, so my behavior didn't surprise her. We were soon married and later had two daughters.
I started my first business when I was in my mid-twenties. A few years later, I bought a large chicken farm. Even with this success, though, my drinking was always a problem. It affected my marriage and family so much that I knew I had to make up my mind to stop drinking. So I tried great efforts. But two years later, I began drinking again.
When I was in my mid-thirties, I sold both of my businesses, and bought the big house on the hill. I was not at all happy, although I had everything that was supposed to make me happy. I sold our big house on the hill and bought a large land, where I built a new house. Our marriage was in big trouble, and my finances took a job as a heavy equipment operator in a road building camp.
My marriage still came apart when I was 38, and my kids had to go through our divorce. I spent 6 months in giving up drinking on a school camp. Nearly a year later, I met my childhood neighbor girl, June. We were married not long afterwards. My kids learned to trust me again and I have two stepchildren that also love me. Happy life continued about ten years. Everything was going so well when I felt there was something wrong with my body. I went to see a doctor, and the medical examination came out that I had ALS(肌肉萎缩症). Record shows that people with ALS generally survive between two to five years after symptoms appear. I've probably had the symptoms for one-and-a-half years already, so I don't know how much time I have left.…God knows…
56. Which of the following is the right order for the author’s experience?
a. He married June.
b. He married Sue.
c. He bought the big house on the hill.
d. He bought a large chicken farm.
e. He succeeded in giving up drinking.
f. He tried but failed to get rid of drinking.
A. a, d, c, b, f, e B. b, d, f, c, e, a C. b, c, d, a, f, e D. f, b, d, c, e , a
57. The underlined phrase “go down the drain”(in Paragraph 3) is closest in meaning to “______”.
A. be out of expectation B. be totally successful
C. become worse and worse D. be safe in one’s pocket
B
Seven well known facts that actually aren't true
1. Penguins Mate for Life
During the mid-2000s, films like "Happy Feet" made penguins all the rage, and young lovers went around spreading the facts like "penguins mate for life." While the idea is sweet, it's not exactly true.
Penguins usually stick with their partners through the mating season, but when it's time to mate again, they choose whomever is convenient, not necessarily their old flame.
2. Vincent Van Gogh Cut Off His Entire Ear
This is not entirely true. It was not his entire ear - just the tip of the lobe（耳垂） - and some say he didn't even do it. Van Gogh lived with artist Paul Gauguin, who had quite a violent temper, and many believe Gauguin actually did the cutting.
Either way, Van Gogh did reportedly send the tip to a prostitute.
3. Napoleon Bonaparte was Short
Everyone knows Napoleon Bonaparte was a tiny man - after all, his nickname was "le Petit Corporal." His reputation for being short even inspired the phenomenon known as the "Napoleon complex."
In reality, Napoleon stood around 5 feet and 7 inches tall, which was very average back in the day. Many believe his nickname was meant as a term of endearment, not a reference to his height.
4. Ben Franklin Preferred a Turkey to a Bald Eagle
The bald eagle is certainly a well-known representation of America, but legend has it that if Ben Franklin had his way, a turkey would have been much better. In reality, Franklin wrote a letter to his daughter mocking the eagle symbol used in a seal(印章) by the Society of the Cincinnati, a private military group.
He said it looked like a turkey and may as well be one.
5. You Have Five Senses
If you remember learning about the senses in elementary school, you know humans possess five: sight, smell, hearing, touch, and taste. Most scientists agree, however, that you have more like 10-20 senses, including pain, hunger, thirst, temperature, and more.
6. George Washington had Wooden Teeth
George Washington is known for three things: being the first president, chopping down a cherry tree, and having wooden teeth. At least one of these is certainly not true. While Washington did have bad teeth, his dentures(假牙) were not wooden.
7. Einstein was a Bad Student
If you ever made bad grades and pulled the old "Albert Einstein used to make bad grades" card with your parents or teachers, you are lucky you got away with it. In reality, Einstein was at the top of his class and mastered calculus when he was barely a teenager.
The reputation he developed for being a bad student had more to do with his behavior. He liked to talk back to his teachers.
61. Which is the true fact according to the passage?
A. Penguins usually stick with their partners through their whole lives.
B. Franklin laughed at the eagle symbol used in a seal and said it looked like a turkey.
C. Napoleon was much shorter than average.
D. George Washington’s false teeth were made of wooden.
62. Why do most people hold the idea that Albert Einstein used to make bad grades?
A. Because he used to like to talk with his teachers.
B. Because he used to be criticized by his parents.
C. Because he used to be different from other students.
D. Because he used to behave badly and usually didn’t respect his teachers.
C
Alibaba started taking the lead in China, simply enough, by connecting big Chinese manufacturers(制造商)with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba’s advantage wasn’t hard to identify: size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year——not charging small sellers a percentage of the sale.
If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You’re looking for what exactly? Why not try it? ” my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.
Alibaba’s original business-to-business model now is secondary to consumer buying. Chinese retail（零售）buying makes up 80% of Alibaba’s profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you’ll ever find. TMall.com is Alibaba’s other big site, where you can find brand name goods from Nike and Unilever near the lowest prices.
What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping—big-box retailers especially —in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.
I have a list of some of my recent purchases on Taobao for a sense of how extensive the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I’m not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher’s iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.
63. Alibaba’s advantage mainly lies in ___________.
A. its big size B. its business-to-business service
C. its not charging small sellers D. its low price
