    After serving as a ski guide in Utah’s back country for more than two decades, a Park City woman is being recognized by Outside Magazine as 2015’s Best Ski Guide.

    Deb Lovci grew up in Colorado and began skiing when she was five years old. Later she moved to Utah and fell in love with the back country of Wasatch Mountains. Lovci has now served as a Ski Utah Interconnect guide for 27 years. “Anything that you slide on snow, I’m in love with, ” she said.

    Lovci leads ski tours through the back country of six different resorts located in the Wasatch Mountains. Lovci typically takes a group of eight to ten people on a ski tour each day, and on average, she takes 300 customers on tours through the back country each season.

I often recall my ski experiences which were fearful at the beginning, but they helped me achieve a success.”

    In a news release, Ski Utah director of communications, Paul Marshall said, “Deb Lovci is one of the most enthusiastic, focused, knowledgeable guides in the industry. Without her as the forefront of our Interconnect Tour, we would not have the success we have. She has been an enthusiastic part of the Interconnect Tour for 27 years and is thought highly of by our customers.”

    In campus violence cases in Beijing during the last five years, 14 percent of the offenders not only beat others, but also insulted(侮辱）them. They slapped(打耳光）others, made them kneel down, and in some cases took off other people’s clothes.

     Violence at schools has been widely reported in media in recent years 一 the violence among teenagers has drawn public and government attention. On Nov 11, the Ministry of Education, along with eight other central sectors, published a guideline on dealing with school violence.

     The guideline stressed that students with serious behavioral problems should be handed over to special schools. Or, in more serious cases, they may take criminal responsibility and be sent to prison.

     “The common tolerant attitude toward violence should be changed,” wrote Jiaxing Daily. “When teenagers do something wrong, we should tolerate and help them when necessary. But all of this has a limit."

Leon McCarthy, 12, was born without fingers on his left hand. That didn’t stop him from being able to do many tasks. But Leon could not grasp more than one object at a time. So Leon’s father, Paul, created a prosthesis(假肢), using a 3D printer. Now Leon has fingers that open and close. “It was a do－it－yourself, father－and－son adventure,” says Paul.

When Leon was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. “The doctor said Leon should first learn to get full use out of the hand he was born with,” says Paul. As Leon got older, his father looked into buying a prosthetic hand, which can cost as much as $30,000. Paul found a more affordable solution.

One day, Paul discovered a video on the Internet about Robohand, a prosthesis created with a 3D printer. He downloaded the free instructions and called Robohand’s creators for advice. They told him all he needed was a 3D printer—which costs around $2,000—and some materials.

Luckily, Leon’s school had recently purchased a 3D printer and it offered to help Paul build the hand for Leon. “We used a soccer shin guard(护胫), cardboard, and tape. They cost about $10.”says Paul.

With his new hand, Leon can do things better. “I can help my mom more, because now I can carry two grocery bags,” he says.

Leon’s father has already built several hands for Leon. Leon helps design each one. He says there’s one thing in particular that he wants to do with a future prosthesis. “The goal,” he says, “is to be able to tie my shoelaces(鞋带)．”

24. Why did Leon's doctor disapprove of his using a prosthesis in his childhood?

A. The prosthetic technology was underdeveloped then.

B. A prosthesis was very expensive at that time.

C. The original hand could do many tasks.

D. To master the disabled hand was important.

25. Leon’s father managed to get Leon a new hand by ________．

A. collecting money on the Internet       B. buying a prosthetic hand

C. purchasing a 3D printer              D. printing a hand

26. The materials used for Leon's hand can be described as ________．

A. cheap and common      B. strange and valuable

C. personal and lovely      D. basic and solid

27. What’s the best title for the text?

A. A DIY Enthusiast                                   B. A Helping Hand

C. A Great Adventure                                D. A Lucky Escape

One day I walked to my favorite cafe for lunch. I ordered a burger and iced tea and went to the outdoor area. While waiting for my meal, a homeless man on a bicycle stopped to ask if there was a grocery store in the neighborhood. After I gave him directions, he asked if I had graduated from Sana Clara University. (I was wearing a SCU T-shirt.) I told him, yes. Little did I know that this simple response would lead to a 90-minute conversation.

The man, Michael, told me he was 50 years old. He was intelligent. Unfortunately, drug abuse had ruined both his formal education and his pursuit of success in the world of work. He drifted from one topic to another, ignoring the fact that my lunch had been brought to me. He clearly had more of a need to talk than I did. I made every effort to give him my full attention, never expecting that our conversation would go on and on ...

Eventually, I did eat my meal, bite by bite between responses in our conversation. Michael was a bit strange in terms of his interests and viewpoints. We had little in common, but he was fascinated with talking with, as he put it, “intelligent people”. I have to admit, I wish our conversation had been limited to ten or fifteen minutes, but when Michael finally rode off on his bike, he thanked me for listening so attentively to him and for my willingness to talk with him for so long. It was then that I realized that, just maybe, that was my purpose in life for today --- to be there, in that place, at that time, to carry on that conversation. On a quick review, I don’t think that I have done anything more important in my life.

21. Why did the author go to the outdoor area?

   A. To go on a date.                     

B. To borrow a bicycle.

   C. To wait for his order.               

D. To show strangers the way.

22. What can we learn about the homeless man?

   A. He received a complete education.

   B. He was dying for communication.

   C. He was curious about everything.

   D. He suffered from a serious disease.

23. Which word can best describe the author?

   A. Considerate.                      

B. Impatient.   

   C. Intelligent.                       

D. Strange.

Dear Mr.Smith,

Yours,

Li Hua

    In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."

    The city planner decided to build an underground drainage (排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's sign each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening. Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

25. The author mentions the joke to show ______.

   A. horses were fairly useful in Chicago                   B. Chicago's streets were extremely muddy

   C. Chicago was very dangerous in the spring              D. the Chicago people were particularly humorous

26. The city planners were convinced by Ellis Chesbrough to_______.

   A. get rid of the street dirt                             B. lower the Chicago River

   C. fight against heavy floods                           D. build the pipes above ground

27.What can we conclude about the moving operation of the Tremont Hotel?

   A. It went on smoothly as intended.                     B. It interrupted the business of the hotel.

   C. It involved Pullman turning ten jackscrews.            D. It separated the building from its foundation.

28.The passage is mainly about the early Chicago's ______.

   A. popular life styles and their influences                B. environmental disasters and their causes

   C. engineering problems and their solutions              D. successful businessmen and their achievements

Children, especially boys, tend to idealize their fathers when they are young．Every little boy wants to grow up to be just like his father, and every little girl thinks her father is the smartest man on the earth．It’s not very easy to be a good father, but it’s not that difficult either．Children will truly enjoy spending time with their fathers, not just when they are kids, but even when they are adults．

Not all children communicate well with their fathers．Communication is often left to mothers, while fathers dispense advice as and when necessary．Don’t expect all conversations to centre around the dinner table．Go to your children’s bedrooms and talk to them about school, their teachers or their friends．Remember that the conversation cannot be one-sided．When your children open up to you, you also need to open up to them．

If your children come home from school feeling upset, go up to them and ask them what is the matter．And if it is something which seems to you to be a silly reason to be upset, don’t voice your opinion．It may be silly to you, but to your children it is important enough．So don’t wave the topic away by telling them not to bother about such stupid things．Simply discussing their problems with them will help them feel better．

Don’t shy away from having discussions about your teenage children’s love lives．Generally speaking, your children are definitely not going to discuss intimate details with you．Try to let them know that you are relaxed about topics on love．Tell your children how you met your wife．It is perfectly normal for children to go through feelings for the opposite sex as they grow up, and by keeping the topic closed for discussion, you are only shutting them off from discussing their feelings with you．All they will do is turn to their friends．

56．To children their fathers are usually very _____．

       A．kind                 B．great               C．serious           D．strong

57．From the second paragraph we can know that _____．

       A．some children don’t like their fathers at all

       B．talking with children around the dinner table is unnecessary

       C．it is better for fathers to communicate more with their children

       D．mothers should communicate less with their children．

58．Suppose your children are worried about something you should _____．

       A．have a talk with them                     B．express your opinion

       C．keep silent                              D．let them alone

59．Which of the following has the closest meaning to the underlined word “intimate” in Paragraph 4?

       A．public              B．personal           C．strange            D．serious

   One night many years ago I was on the bridge of a ship passing one of our large cities on a quiet night. I saw its lights  41   in the sky and heard the city’s noises.

   I have spent twenty-five years on boats. Now I am a   42  . My job is to bring in the large luxury   43   and stay with them until they are safely stopped in their ports.

   I felt very   44   the first time I ever docked a big liner. She came   45  up the harbor on a flood tide and towered high over the short little boat. As we drew alongside, a doorway opened   46  at water level and two smartly dressed sailors helped me aboard.

   I was escorted to the bridge where I   47   from the captain. I realized I was in   48   of a great ship worth millions of dollars. Having docked several of the large liners, I realized I was not important,    49   simply the quarterback who called the signals.

   In spite of   50   we read in the newspapers, I have great faith in this country, praying that a peaceful understanding will come to this   51   world, so that my children can grow up in a world full of happiness. I believe this will come   52   .

   I remember the understanding and   53   that took over this country, back in 1949, when a little girl named Kathy Fiskus   54   into an old well in California. Engineers and sandhogs and people in all walks of life worked almost three days, and when they got her out she was dead.

   People sent in thousands of dollars in   55  funds, but those who did the work and   56  the equipment wouldn’t take the money. They worked for bigger things. I talked to captains of foreign   57   that came into New York Harbor, and they were just as   58  as we Americans over the tragedy.

   I believe some   59   will be found to work together for world peace with the same sympathy and understanding that people worked to rescue little Kathy Fiskus. I believe God will   60   bring this about.

When 7-year-old Warren Buffett said,“I will be the richest man one day,” his friends made fun of his “daydreaming”. But ever since then the little boy has set about learning how to make money by selling drinks, delivering newspapers and buying stocks. The American had already earned $9,000 (equal to $90,000 today) by the time he graduated from high school.

   And this month the 78-year-old man, who earned his fortune by making a lot of sound investment in the stock market, took the place of Microsoft founder, Bill Gates, as the world’s richest man. Gates’ worth declined $1.5 billion to $55.5 billion in 33 days after the recent financial storm, according to Forbes Magazine.

   Buffett, the only son of a stockbroker, was ready to think outside the box to develop his business from a very early age. At 8, he went to golf courses collecting and selling the used balls. At 11 when he sold soda pop door-to-door with a friend, the pair collected lids on streets to judge which flavor was the most popular.

   As a paper boy during high school, Buffett delivered two competitor papers, so that even when customers canceled one of the subscriptions, he could still make a profit from the other. With his paper delivery savings, Buffett bought 162,000 square meters of farmland and collected rent. Young Buffett stepped into the stock market at 11 but earned only $5. The experience taught him one of the virtues in investing, patience.

   After graduating from university, Buffett started his venture with stocks with his childhood earnings and money from friends. He researched the stocks and just bought those of solid companies that were undervalued and inexpensive at the time. By sticking to companies such as American Express and Coca-Cola, Buffett has become rich.

   “Learning is important to Buffett’s success. He is a learning machine who can spend his entire day reading. He keeps learning from books, street smarts and investigation, from both success and failure. In this way, he over-achieved his aptitude (能力).” said Charlie Munger, his longtime business partner.

D He bought 162,000 square meters of farmland by selling soda pop.

18. How did Buffett behave at the stock market?

A. He often prefers some inexpensive stocks.

B. He will buy the stock whose price is lower than its value.

C. He always borrows money from his friends to buy stocks.

D. He will sell the stock if its price doesn’t go up.

19. Which is the main factor that determines Buffett’s success?

A.  His education.                   B. His family background.

C.  His desire to learn.                D. His cooperation with his partner.

20. What can we infer from the passage?

On August 16, 1977, Elvis Presley saved me.

The previous afternoon, I played with my six-year-old peers in Heather Peters^’ backyard. I was enjoying my cake, when Heather asked me where my sleeping bag was. Only then did I know this party was a sleepover. The word “sleep-over” to a six-year-old bed-wetter is like what “cancer” means to an adult. But what if I told them I was a bed-wetter? At least with cancer, people gather at your bedside instead of running from it.

I thought of a way to escape. I would explain that I needed my mother's permission to spend the nights. But as I called my Mom, Heather stood beside me to listen. She granted permission! Then I would be sleeping in the same living room as the other girls. I didn't bring my own pajamas (睡衣)，so Mrs. Peters offered me Heather's pajamas.

As the other girls drifted into their sweet dreams, I tried to stay awake. “Do I need to go again? I'll stay up to go one more time.. .”.Of course , I finally fell asleep.

The next morning , I was the first to wake up. I was warm! I lay in panic for what seemed like hours before the other girls started to wake up. I did the only thing I could do — I pretended that the bed-wetting didn't happen. I got up, took off Heather's pajamas and changed into my clothes like the other girls.

Mrs. Peters walked into the room, and before she could say anything, she stepped right onto the pile of my wet pajamas. My heart stopped as I watched her face burn red. “WHO DID THIS?” She screamed, with a look so frightening. Should I answer? And that was when it happened — Mr. Peters came in and grabbed his wife , ‘‘Elvis Presley died!”

The news of the King's death overtook Mrs. Peters, and I ,was spared. I got home without the other girls knowing what had happened.

21. The author had to spend the night at Peters' because ________.

A. she enjoyed her cake there         B. the famous singer Elvis Presley died that night

C. her mother allowed her to do so    D. It was a routine of the party

22. Mrs. Peters got angry because ________.

A. she found the wet pajamas                      B. Elvis Presley passed away

C. her husband was rude to her                   D. all the girls slept at her house

23. From the story, we know Mrs. Peters was ________.

A. a bad-tempered woman                          B. a fan of Elvis Presley

C. a woman for perfection                          D. a woman who hated to wash pajamas

24. The passage is mainly about ________.

A. an embarrassing childhood incident       B. a fan-purchasing experience

C. the shocking death of a famous singer     D. an unfriendly hostess

Editing humans’ DNA

If you could change your child’s DNA in the future to protect them against disease, would you? it could be possible because of technology known as CRISPR-Cas, or just CRISPR.

CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA; it also uses an enzyme (酶) that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.
   The uses of CRISPR could mean that therapies(疗法) are developed for everything from Alzheimer’s to cancer to HIV. By allowing doctors to put just the right cancer-killing genes into a patient’s immune system, the technology could help greatly.
   In April scientists in China said they had tried using CRISPR to edit the genomes (基因组) of human embryos. Though the embryos would never turn into humans, this was the first time anyone had ever tried to edit DNA from human beings. With this in mind, the US’ National Academy of Sciences plans to discuss questions about CRISPR’s ethics (伦理问题).
   For example, CRISPR doesn’t work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities.
   There are also moral(道德的) questions around “playing God”. Of course, medicine already stops natural things from happening —— for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn’t keep going.
   A harder question is whether it is ever right to edit human germ-line (种系) cells and make changes that are passed on to children. This is banned(禁止) in 40 countries and restricted(限制) in many others. However, CRISPR means that if genes can be edited out, they can also be edited back in. It may be up to us as a society to decide when and where editing the genome is wrong.
   Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too; parents might want to make their children more intelligent at all costs.”
    In the end, more research is still needed to see what we can and can’t do with CRISPR. “It’s still a huge mystery how we work,” Craig Mello, a UMass Medical School biologist and Nobel Prize winner, told The Boston Globe. “We’re just trying to figure out this amazingly complicated thing we call life.”
