The town I live in is about to put cameras at all traffic lights to catch people who run red lights. It 34 me of how many people I’ve seen who take the yellow light as a 35 to go faster. I also can’t understand why people don’t move when the traffic light has turned green. Above all, there are those 36 situations in which someone doesn’t even 37 that the light turns red, and just keeps going. That is why so many 38 happen! All these situations make me 39 the purpose of traffic lights.
40 , it’s even more frightening to imagine letting people make their own decisions at
41 crossroads. Do the biggest cars get to go first？ Who decides who goes next？ So I guess I do like the idea of a system to 42 traffic. And I’ll do my best to obey the traffic rules：to go, to be cautious, and to stop when I’m 43 to.
It occurs to me that my parents have done much the same for me in terms of teaching me how to live. They have given me many 44 lights：to get along well with others, to listen and talk to them, to help others, and to live with joy and purpose. They have also given me some red lights 45 my life goes astray（误入歧途）：not to be greedy, to keep my temper, and to control my desires. And there 46 have been some yellow caution lights：to watch how much I drink, to keep control of my behavior, and to 47 school regularly and work hard.
If I obey these rules, my life will be as good as it can be. Just as I’m wise to pay attention to the traffic lights when I’m walking across the street,I’m wise to pay attention to the “ 48 _signals” given to me by my parents.
34. A. convinces B. informs C. reminds D. warns
35. A. sight B. signal C. message D. switch
36. A. instant B. exciting C. dangerous D. cautious
37. A. notice B. sense C. remember D. think
38. A. events B. problems C. situations D. accidents
39. A. look for B. wonder about C. care for D. worry about
40. A. Besides B. Anyway C. Instead D. However
41. A. noisy B. narrow C. crowded D. colourful
42. A. control B. direct C. improve D. serve
43. A. supposed B. used C. devoted D. delighted
44. A. safe B. green C. beneficial D. helpful
45. A. unless B. when C. before D. till
46. A. still B. even C. only D. also
47. A. start B. attend C. finish D. miss

第三部分：阅读理解（共14小题；每小题2分，满分28分）
阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题纸上将该选项标号涂黑。
A
Eddie’s father used to say he’d spent so many years by the ocean, breathing seawater. Now, away from that ocean, in the hospital bed, his body began to look like a beached fish. His condition went from fair to stable and from stable to serious. Friends went from saying, “He’ll be home in a day” to “He’ll be home in a week.” In his father’s absence, Eddie helped out at the pier （码头）, working evenings after his taxi job.
When Eddie was a teenager, if he ever complained or seemed bored with the pier, his father would shout, “What？This isn’t good enough for you？” And later, when he’d suggested Eddie take a job there after high school, Eddie almost laughed, and his father again said, “What？This isn’t good enough for you？” And before Eddie went to war, when he’d talked of marrying Marguerite and becoming an engineer, his father said, “What？This isn’t good enough for you？”
And now, regardless of all that, here he was, at the pier, doing his father’s labor.
Parents rarely let go of their children, so children let go of them. They move on. They move away. It is not until much later, as the heart weakens, that children understand; their stories, and all their accomplishments, sit on top of the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives.
Finally, one night, at his mother’s urging, Eddie visited the hospital. He entered the room slowly. His father, who for years had refused to speak to Eddie, now lacked the strength to even try.
“Don’t sweat it, kid,” the other workers told him. “Your old man will pull through. He’s the toughest man we’ve ever seen.”
When the news came that his father had died, Eddie felt the emptiest kind of anger, the kind that circles in its cage.
In the weeks that followed, Eddie’s mother lived in a confused state. She spoke to her husband as if he were still there. She yelled at him to turn down the radio. She cooked enough food for two. One night, when Eddie offered to help with the dishes, she said. “Your father will put them away.” Eddie put a hand on her shoulder. “Ma,” he said, softly, “Dad’s gone.”
“Gone where？”
49. In Paragraph 4, the writer indicates that ________.
A. Children like moving away from them parents
B. Children often feel regretful because they leave their parents
C. Children wouldn’t have achieved so much without their parents’ support
D. Children can never understand how much their parents have devoted to them
50. The underlined senten ce probably means “________”.
A. Don’t give it up
B. Don’t worry about it
C. Don’t let him down
D. Don’t touch it
51. Which of the following shows the right order of the story？
a. Eddie’s father died.
b. Eddie worked as a taxi driver.
c. Eddie married Marguerite.
d. Eddie was bored with his father’s job.
A. bacd
B. dcab
C. bcda
D. dcba
52. From the last part of the passage, we learn that ________.
A. Eddie’s mother liked to listen to the radio
B. Eddie often helped his mother wash the dishes
C. Eddie and his wife lived in his mother’s apartment
D. Eddie’s mother missed her husband so much that she was at a loss
B
Among the Boys is a unique after-school program for boys living in the Highland Park neighborhood of our city. The organizational task is to provide males living in low-income and public housing with opportunities to discover their ability to change challenges into possibilities. The program includes an academic part as well as specific plans for supporting the overall development of the participants. Among the Boys uses painting as an instrument for helping boys examine their world, discuss it, and develop positive ways of handling the challenges they face daily. Young men present personal challenges to the group, such as a recent fight or the long-term drug abuse they observe in their neighborhood. After guided discussion, the youth work as a team, determining how to best represent the issue at hand in a painting. The resulting paintings and explanations of these paintings provided by the young people suggest that something profound （深远的） occurs through this process. These young men are learning a healthy way to express and cope with the pain and suffering they feel. Art serves as a healing process and a structured method of teaching teamwork, nonviolent values, conflict handling and problem-solving skills.
Activities in Among the Boys are in agreement with the best practices in the prevention of high-risk behavior. First, community-based youth development programs are considered important parts of a comprehensive prevention method, particularly in high-risk
neighborhoods. Second, compensatory （补偿） education that targets at risk youth for academic failure is also considered an effective prevention method. Third, interventions （介入）aimed at improving youth’s moral reasoning, social problem-solving, and thinking skills are reported to be effective methods for reducing violence in high-risk populations, especially when carried out with elementary school-aged boys. Finally, Among the Boys has an adapted tutoring part, considered an effective prevention tool. Tutorring is typically a one-to-one match between a tutor and a youth, but Among the Boys employs what is referred to as “group tutoring.” Among the Boys makes up for its high student-tutor ratio（比例） with quality and quantity of time, as the program meets after school, on Saturdays, and all day during the summer, and is staffed primarily by males, an unusual quality among educational programs.
Among the Boys is rare and successful form of grassroots program, and represents the dream of a successful male who grew up in the Highland Park neighborhood and has returned to make a valuable contribution to his community.
53. Which of the following best describes the organization of the second paragraph？
A. A theory is presented and proved with data.
B. A statement is made and supported with reasons.
C. A problem is put forward and solutions are suggested
D. A situation is described and a prediction is provided
54. In discussing Amon g the Boys’ tutoring part, the author implies that ________.
A. Among the Boys employs a traditional tutoring model which proves effective
B. tutoring is effective only when it is carried out with elementary school-age boys
C. tutoring prevents the you th’s attention from wandering off while having a discussion
D. increased hours with a group can be as effective as a one-to-one tutoring relationship
55. The founder of Among the Boys________.
A. sought contributions to make his program successful
B. started the program for the same neighborhood in which he grew up
C. is seeking reelection for the Highland Park community school board
D. was a successful graduate of Among the Boys when he was a youth
C
Do you want to live with a strong sense of peacefulness, happiness, goodness, and self- respect？The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.
Here’s an example to show how honorable actions create happiness.
Say a store clerk fail s to charge us for an item. If we keep silent, and profit from the clerk’s mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness？
In the first case, where we don’t tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk’s attention causes different things to
happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable action, we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it’s easy to think and act honorably again when we’re happy. While the positive cycle can be difficult to start, once it’s started, it’s easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.
56. According to the passage, the positive action in the example contributes to our ________.
A. self-respect
B. financial rewards
C. advertising ability
D. friendly relationship
57. The author thinks that keeping silent about the uncharged item is equal to ________.
A. lying
B. stealing
C. cheating
D. advertising
58. How will we feel if we let the clerk know her mistake？
A. We’ll be very ex cited.
B. We’ll feel unfortunate.
C. We’ll have a sense of honor.
D. We’ll feel sorry for the clerk.
59. Which of the following can be the best title of this passage？
A. How to Live Truthfully
B. Importance of Peacefulness
C. Ways of Gaining Self-respect
D. Happiness through Honorable Actions
D
People who have a fear of ugly insects will want to stay far away from Lake Tawakoni State Park in north Texas, US. A giant spider web was recently found there. The thick web is swarming （云集） with millions of little spiders.
Stretching across several acres it blankets a number of trees, bushes and even the ground.
While the web may make some people nervous, it has become a big attraction for others—especially for unlucky insects. “At first, it was so white that it looked like fairyland,” said Donna Garde, the park’s manager. “Now it’s filled with so many mosquitoes that it’s turned a little brown.”
Most spiders work alone, which is why the discovery of the huge web has caused such a stir. Scientists across the country have been debating its origin.
Some spider experts’ say the monstrous web may have been weaved by social spiders. Social spiders work together to build larger webs to catch small insects. However, those webs take years to build. Park officials say this web was formed in just a few months.
Others say it could be the work of millions of tiny ballooning spiders. These types of spiders ‘fly’ by throwing out thin threads of silk, which they use to ride air currents （气流）. In 2002, a similar giant web made by ballooning spiders was discovered in a field in Canada.
Texas entomologist （昆虫学家）Herbert Pase says the giant web is very unusual. “From what I’m hearing, it could be a once-in-a-life-time event,” he said.
But John Jackman, an entomologist and professor at Texas A&M University, disagrees. Jackman says he hears reports of similar webs, like the one in Canada, every few years. “There are a lot of folks that don’t realize spiders do that,” he said. “Until we get some samples sent to us, we won’t know what species of spider we’re talking about.”
Park officials expect the web to last until fall when the weather gets cooler. That’s when the spiders begin dying off in the park.
60. What is the main reason for scientists’ excitement and argum ent about the giant web？
A. Most spiders work alone, which makes it hard to understand how the web formed.
B. The huge web causes too many mosquitoes to be killed, which is unbelievable.
C. No similar discoveries have ever been made throughout the world so far.
D. The web forces people to stay far away from Lake Tawakoni State Park.
61. Which of the following will John Jackman most probably agree to？
A. Possibly such a big web can only be seen once in one’s whole life.
B. The web will be there as long as the weather is warm enough.
C. It is not very uncommon for spiders to weave big webs like that.
D. A lot of spiders will die off for the sake of the big web.
62. Which of the following sentences about the web in north Texas is TRUE according to the
passage？
A. It is not certain yet what spiders made the web.
B. What makes the web special is its color.
C. It took years for the web to come into being.
D. The web is used by spiders to protect themselves.

We were wet to the skin, and we still sang and laughed happily.

There are various students’ clubs in our school, which are fairly popular with the students. Among them, there exists the literature club, where students can share their respective opinions on a novel. The play club, cartoon union and photograph association are all on the top of the list.
