Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. The mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure(基础设施)that must be maintained.
Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.
Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.
Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.
Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.
Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.
A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.

When you're surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters to record the computer user's age, gender, location, favorite movies and hobbies.
The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated (高科技) software called a “ beacon" to capture what people are typing on a website.
Lotame packages that data into profiles (个人资料) about individuals, only without their names, and sells the profiles to companies seeking customers. Batches of such data may be sold for a few dollars.
The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web.
The "cookie" a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news. There are new and more complex tools such as “beacons” which scan in real time what people are doing on a webpage. These beacons instantly assess the Internet user's location, income, shopping interests and even medical conditions.
Millions of Internet users around the world also face unprecedented (空前的) threats. Private, sensitive, personal and business information is being gathered and sold without their knowledge.
Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were installing intrusive files on visitors' computers. These include MSN. com and Yahoo. com.
Next time you visit a webpage and find an ad banner advertising something you've been planning to buy, don't be amazed that your computer can read your mind.The purpose of the passage is to __________.
| A．introduce a tiny file in a computer-a single code |
| B．show how your individual information was let out when you surf the Internet |
| C．show how to protect your privacy |
| D．introduce a sophisticated software called a “beacon" |
All of the following statements are False except __________.
| A．Lotame sells the profiles about individuals to companies seeking customers with their age, gender, location, hobbies and names |
| B．spying on Internet users is the fastest-growing businesses on the World Wide Web |
| C．some of the biggest websites in the US know they were installing intrusive files on visitors' computers |
| D．a tiny file in a computer-a single code consisting of a long series of numbers and letters can record users' information |
It can be inferred that __________.
| A．because the data is used harmlessly the Internet users around the world will not face threats |
| B．when a person surf the Internet, his personal details may be let out without his knowledge |
| C．your __________ computer can really read your mind |

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 share your children’s curiosity.
Firstly, listen to their questions. I once visited 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 silence. 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 discussion, 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.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 |

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens and white paper, I decided that the act of writing must be the most wonderful thing in the world.
Years later, during her final illness, mother kept different things for my sister and brother. “But the desk,” she said again, “is for Elizabeth.”
I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.
They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface”.
As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
I posted the letter and waited for her answer, none came.
My hope turned to disappointment, then little interest and, finally, peace. It seemed that nothing happened. I couldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
Now the present of her desk told me that she was pleased that writing was my chosen work though she’d never been able to. I cleaned the desk carefully and found some papers inside —a photo of my father and a one-page letter, folded(折叠) and refolded many times.
Give me an answer, my letter asks, in any way you choose, Mother, you always chose the act that speaks louder than words.The writer began to love her mother’s desk _______.

James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9.There, a school teacher asked the youth his name.
"J.C., "he replied.
She thought he had said "Jesse", and he had a new name.
Owens ran his first race at age 13. After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second year student, in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.
A week before the Big Ten meet, Owens accidentally fell down a flight of stairs. His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.
The stage was set for Owens victory at the Olympic Games in Berlin the next year, and his success would come to be regarded as not only athletic but also political. Hitler did not congratulate any of the African American winners.
"It was all right with me, "he said years later. "I didn’t go to Berlin to shake hands with him, anyway."
Having returned from Berlin, he received no telephone calls from the president of his own country, either. In fact, he was not honored by the United States until 1976, four years before his death.
Owens Olympic victories made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks, motorcycles and dogs.
"Sure, it bothered me, "he said later. "But at least it was an honest living. I had to eat."
In time, however, his gold medals changed his life. "They have kept me alive over the years, "he once said. "Time has stood still for me. That golden moment dies hard."Owens got his other name "Jesse" when ________.
A. he went to Ohio State University
B. his teacher made fun of him
C. his teacher took "J. C." for "Jesse"
D. he won gold medals in the Big Ten meet In the Big Ten meet，Owens__________.
| A．hurt himself in the back |
| B．succeeded in setting many records |
| C．tried every sports event but failed |
| D．had to give up some events |
We can infer from the text that Owens was treated unfairly in the US at that time because________.
| A．he was not of the right race |
| B．he was the son of a poor farmer |
| C．he did not shake hands with Hitler |
| D．he did not talk to the US president on the phone |
When Owens says "They have kept me alive over the years ", he means that the medals __________.
| A．have been changed for money to help him live on |
| B．have made him famous in the US |
| C．have encouraged him to overcome difficulties in life |
| D．have kept him busy with all kinds of jobs |
What would be the best title for the text?
| A．Jesse Owens, A Great American Athlete |
| B．Golden Moment — A Life time Struggle |
| C．Making A Living As A Sportsman |
| D．How To Be A Successful Athlete |
Boys' schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.
Far from the traditional image of a culture of aggressive masculinity (阳刚), the absence of girls gives boys the chance to develop without pressure to conform to a stereotype, a US study says.
Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to conform to the "boy code" of hiding their emotions to be a "real man".
The findings of the study go against received wisdom that boys do better when taught alongside girls.
Tony Little, headmaster of the British boys-only school, Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.
The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.
But in single-sex schools teachers can tailor lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.
Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have more acute vision learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around, James found.
Single-sex education also made it less likely that boys would feel they had to conform to a stereotype that men should be "masterful and in charge" in relationships. "In mixed schools boys feel compelled to act like men before they understand themselves well enough to know what that means, " the study reported.The author believes that a single-sex school __________.
| A．forces boys to hide their emotions to be "real men” |
| B．helps to cultivate masculine aggressiveness in boys |
| C．encourages boys to express their emotions more freely |
| D．naturally reinforces in boys the traditional image of a man |
It is commonly believed that in a mixed school boys __________.
| A．perform relatively better |
| B．behave more responsibly |
| C．grow up more healthily |
| D．receive a better education |
What does Tony Little say about the British education system?
| A．It fails more boys than girls academically. |
| B．it focuses more on mixed school education. |
| C．It fails to give boys the attention they need. |
| D．It places more pressure on boys than on girls. |
According to Abigail James, one of the advantages of single-sex schools is __________.
| A．teaching can be tailored to suit the characteristics of boys |
| B．boys can focus on their lessons without being distracted |
| C．boys can choose to learn whatever they are interested in |
| D．teaching can be designed to promote boys' team spirit |
Which of the following is characteristic of boys according to Abigail James' report?
| A．They enjoy being in charge. |
| B．They have sharper vision. |
| C．They conform to stereotypes. |
| D．They are violent and sexist. |
