Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.
My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren’t written until the final threat.
I’ve been a newspaperman all my adult life. My daughter is a university graduate working toward her master’s degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student (技校学生).They’re called “motorheads” by the rest of the student body.
When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he’s a good kid,” I wanted to say. “And smart, really.”
I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don’t often make school honor rolls.
But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don't have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it, but let him go ahead, for I had nothing to lose.
My son, with other motorheads, fixed the car. They got parts from a junkyard, and ability from vo-tech classes. The cost was $25 instead of $800.
Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbors and co-workers trust their car repair to him.
These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.
I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don^ need clones in footsteps or anywhere else.
My son may never make the school honor roll. But he made mine.
36. The author let his son repair the car because he believed that .
A. his son had the ability to fix it
B. it would save him much time
C. it wouldn't cause him any more loss
D. other motorheads would come to help
37. What did the author realize in the end?
A. It is unwise to expect your child to follow your path.
B. It is important for one to make the honor roll.
C. Architects play a more important role than builders.
D. Motorheads have greater ability than office workers.
【答案】36. C 37. A
细节理解题。根据第六段的句子I doubted it, but let him go ahead, for I had nothing to lose.可知，作者认为儿子修车不会给他带来任何损失。故选C。
推理判断题。根据倒数第二段的句子Most important, I have learned that fathers don^ need clones in footsteps or anywhere else.可知，作者最后意识到希望孩子按自己期望的道路走是不明智的。故选A。
In the hills outside Missoula, Montana, wildlife biologists are looking at how climate change affects something very small: the snowshoe hare.
Life for snowshoe hares is pretty stressful 一 almost everything in the forest wants to eat them.
Alex Kumar, a graduate student at the University of Montana, lists the animals that are hungry for hares. “Lynx, foxes, coyotes, […. even] red squirrels.”
Kumar and field technician Tucker Seitz spend months searching these woods for hares, often listening for signals from hares they've already put radio collars on.
They catch other hares with wire traps about the size of a breadbox, with some apple as bait (诱饵). Most of the hares they track live less than a year — a hazard (风险）of being what Kumar calls “the cheeseburger of the ecosystem”.
But snowshoe hares have a special skill: camouflage. They're brown during the summer, but turn white for the snowy winter months.
“There’s times when you’re tracking them and you know they’re really, really dose, and you just can’t find them,” he says.
Hares switch color in the spring and fall in response to light, when the days get longer or shorter. But if the snow comes late, you get a white hare on brown ground.
“And they really think that they’re camouflaged,” Kumar says. “They act like we can’t see them.”
Kumar calls this “mismatching,” and it's becoming more of a concern with climate change.
“If the hares are consistently molting (脱毛) at the same time, year after year, and the snowfall comes later and melts earlier, there’s going to be more and more times when hares are mismatched,” he says.
Scott Mills of North Carolina State University leads the research. He says they're finding that mismatched hares die at higher rates. That’s a concern for the threatened Canada lynx, which mainly eats these hares.
“It’s a very clear connection to a single climate change stressor,” Mills says.
Hares might be able to adapt over time. Some snowshoe hares in Washington State don't turn white at all. Mills is trying to figure out whether hares and other wildlife can adapt as fast as the climate is changing.
“But how fast is too fast?” he asks.
38. The word “camouflage”（Paragraph 6) is closest in meaning to .
A. escaping B. hiding
C. fighting D. scaring
39. According to the passage, snowshoe hares can now be easily discovered by their enemies because they .
A. change their fur color to white too late
B. haven’t adapted to climate change
C. can no longer adapt to the change of light in spring and fall
D. find it more and more difficult to molt at the same time each year
40. Which best describes Mills' tone in the passage?
A. Approving. B. Enthusiastic.
C. Concerned. D. Doubtful.
【答案】38. B 39. B 40. C
词义猜测题。根据第六段They're brown during the summer, but turn white for the snowy winter months.在夏天他们是棕色的，但是有雪的冬天数月里变成白色。可知他们有一个特殊的技能“伪装”，划线词最接近的词义是B. hiding
推理判断题。倒数第三段中Mills描述了现状，并提出了担忧“He says they’re finding that mismatched hares…which mainly eats these hares.”，再结合最后一段他的疑问可以推出他的语气是“担心的”，故选C。
Nelle Harper Lee? better known by her pen name Harper Lee, was an American novelist widely known for To Kill a Mockingbird, published in 1960. Immediately successful, it won the 1961 Pulitzer Prize and has become a classic of modem American literature. In 1991 an organization conducted a survey that made readers identify books that had “made a difference” in their lives. The result? Lee's book trailed only The Bible. Alongside the works of Shakespeare and Twain, this novel remains one of the most widely taught books nationwide, reaching about 70% of American public schools. What makes it such a typical read for young people?
English class is a place where young Americans come to know themselves. In the folds of dusty books, students can make contact with humanity beyond the shallow small talk of the school hallways. Disturbed by hormones (荷尔蒙）and anxiety, teenagers get through school with confusion and frustration. Literature is a safety valve (安全阀）一 it promises relief, a place to figure out one's problems and get to know oneself better.
The novel particularly distinguishes itself in this aspect. It speaks in a child's voice without treating its readership as children. Some critics have called it an “impossible”evement, a children's book penned by a well-educated adult — it's unlikely that a child like Scout could exist in the real world. But that's exactly what makes it such a charming, attractive read for young people. It indicates the consciousness of a well-educated adult facing difficult realities, but describes it through the light and playful voice of a curious little girl.
Gaby Hick, a third- year student focused on English literature at Brown University, calls it ^one of the first books that kids and young adults read that deals with serious issues 一 rape, race, mental issues”. She adds, “The story makes these adult themes accessible because of Scout.” The book’s setting, a small town in Alabama affected by the Great Depression of the 1930s, may appear very different from the experience of most kids reading it today. But Lee's words make her story feel alive and present.
In 2006, however, critic Thomas Mallon expressed his regret about the book's avoiding complexity in The New Yorker. But her novel makes a great teaching tool for teenagers precisely because its moral view is as clear as that of one of Aesop's Fables. That absence of ambiguity (含糊其辞）in this novel doesn't mean the novel is free of challenging ideas, either. Will Serratelli, another literature student at Brown says, “There aren’t many hard moral questions being asked …but it opens up all these other questions that 1 hadn't thought about before. My English teachers always asked, Do you sympathize (同情）with this character? Would you want to hang out with them?’ When you give a kid a book where those questions don't even need to be asked, it forces them to dig deeper.”
Mallon's criticism is accurate in that this novel may present too limited a view of racism in America. That's especially problematic because it is one of the only books consistently assigned to American students that acknowledges (承认）racial discrimination (歧视）at all. However, To Kill a Mockingbird may owe some of its popularity as a teaching text to the fact that the narrative voice is a white one. Naomi Vamis, an African Studies student at Brown says, “It's another practice of telling stories about black people through white central characters,” she says.
While the novel is undoubtedly worth its place in the classroom, English teachers may do well to consider that it is a white author's perspective — and ought to be the only beginning of a dialogue about race and never the final word. But as a gateway to more mature ideas, and as a YA(young adult) distillation (提炼）of complex concepts young people may not have grasped before, Lee's novel is invaluable.
41. According to the passage, the novel To Kill a Mockingbird can help us .
A. reduce much anxiety for fear of losing ourselves
B. understand what the real personality of human is
C. know more about the past U.S. economic situation
D. find and deal with some other complicated questions
42. What does the underlined word “trailed” most probably mean in Paragraph 1 ?
A. Was as good as. B. Tried hard to defeat.
C. Went along the same route as. D. Had a lower score than.
43. What can we conclude from Will Serratelli's statement underlined in Paragraph 5?
A. The kids are unwilling to answer challenging questions.
B. The kids have to face more moral questions.
C. The kids tend to sympathize with the characters.
D. The kids are motivated to think further.
44. Why is the novel well received by teenagers in the U.S.?
A. Because it reveals racial discrimination in America.
B. Because a white author tells the stories about black people.
C. Because it makes some serious adult issues accessible.
D. Because it is widely used as a tool for moral judgments in society.
45. What is the authors purpose in writing the passage?
A. To tell us about the content of the novel.
B. To explain the reasons for its popularity.
C. To introduce some different comments.
D. To approve of the creative writing style.

The basics of infrastructure (基础设施）design
It is rightly pointed out by various intellectuals that the lifestyle of today is vastly different from that of the earlier times especially in terms of its pace. Lifestyle of today is remarkably fast paced and so in order to catch up with such a pace of life, the adoption of smart and time saving methods is of real significance. Well, the highways have certainly contributed in this direction and have made our lives a lot easier. Thanks to the modern flyovers and expressways, a single route can be accessed by twice the number of vehicles at the same time.
These facilities and supplies have made our lives double free but it needs to be realized that designing and constructing it is a very complex and a long process. You have to hold firmly to the various rules of designing, government standards and most importantly, their safety and usability for the people. In the end it is a joint effort of a number of skilled engineers, scientists and statisticians. The material that is used in the construction is finalized after it undergoes certain tests for evaluating their qualities like hardness, roughness, thickness and all that is required.
Some of the points you have to take care of while laying an infrastructure design are as follows:
The basic layout (布局）of the road — At this level of planning, various civil engineers have meetings to figure out the basic requirements of the road like thickness of the asphalt（沥青）,the size of lanes, distance to be covered, degree of curves and much more.
