Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”

At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”

However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”

See in your mind’s eye where you really want to be in ten years’ time．Choose your own values, activities, and relationships rather than copying tubers．

While working with troubled teens, I used to haste them do a Ten Years game in the Future exercise．I asked them to write a letter to a friend as if it was ten years in the future．Most of these boys and girls didn’t think about the next week, much less ten years to come．This lack of “foresight”was a major reason why their lives were pretty messed up．But the real story is what happened to me．I did the exercise right along with them on many occasions, writing my dreams in detail．In my letter to a friend, I had moved to the country, built my own home, authored a book, and started my own business．

Over the next ten years, something magic happened．All my dreams became true, almost as if orchestrated (精心安排) by an unseen hand．I realized that something very powerful was happening, more powerful than expected．I did write books and start my business．We did move to the country and I did build my own home．

This letter to a friend will become a magnetic factor in your life．Your vision will guide you in your yearly goals, your monthly goals, and your daily activities．

You must write your letter as if it has already happened．For example:

“Leslie, I just wanted to make contact again and tell you about my life．I started my own gardening business in 2012 and it’s really taken off．”

“Dear Harold, I met the love of my life in 2016 and we moved to Hawaii where Frank works in a bookstore and I give surfing lessons everyday．We love it．”

Remember, describe all the details as if they have already happened．This will help you make it more real for you．

Every year landslides (滑坡) cause 25 to 50 deaths and $1.5 billion in damage in the United States. They account for 15 percent of the deaths from natural disasters in Europe. And in December, a single event killed more than 200 people in the Philippines. Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties. Shaking drills produce harmful dust and loosen heavy, dangerous debris (岩屑). "It's quite a risky job," says Giorgio Pezzuto of D'Appolonia, an engineering company in Italy.

D'Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber. "The idea is to operate a machine far away that can drill without a human being on board," says Pezzuto, manager for the project, which is supported by the European Commission. Engineers claim that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged mechanical spider, has cost at least $2 million so far. The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope's stability. Testing should begin in May.

The underlined word "event"(in Paragraph 1) refers to _____.

A. landslide  B. machine   C. earthquake     D. flood

The purpose in writing this text is _____.

A. to tell people how serious the damage caused by landslides is

B. to tell people that sending workers to stabilize mountainsides is a risky job

What does the robot look like?

A. A human being.  B. A spider. C. A truck.  D. A drill.

The biggest advantage of this product is that _____.

A. it will be faster and cheaper than manual labor

B. it can climb mountainsides, drill holes, insert bars and cement

C. it can collect data on the slope's stability

D. it can drill without a human being on board

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts(变换) back and forth from one level to the other.

Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend(建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

49. During REM, ______

A. you move restless                                         B. you start dreaming

C. your mind stops working                                         D. your eyeballs move quickly

“A good book for children should simply be a good book in its own right,” says Mollie Hunter. Born and brought up near Edinburgh, Mollie has devoted her talents to writing primarily for young people. She firmly believes that there is always and should always be a wider audience for any good book whatever its main market is. In Mollie's opinion it is necessary to make full use of language and she enjoys telling a story, which is what every writer should be doing. “If you aren't telling a story, you're a very dead writer indeed,” she says. With the chief function of a writer being to entertain, Mollie is indeed an entertainer. “I have this great love of not only the meaning of language but of the music of language,” she says. “This love goes back to early childhood. I've told stories all my life. I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them, I said I wanted to work with dogs, and the teacher always said ‘Nonsense, Mollie, dear, you’ll be a writer.’ So finally I thought that this woman must have something, since she was a good teacher and I decided when I was nine that I would be a writer.”

This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical and gives a picture both of Mollie's ambition and her struggle towards its achievement. Thoughts of her childhood inevitably(不可避免地)brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields—sadly now covered with modern houses.“I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I'll never go back,”she said. “Never.”“When I set one of my books in Scotland,”she said,“I can recall my romantic (浪漫的) feelings as a child playing in those fields, or watching the village blacksmith at work. And that's important, because children now know so much so early that romance can't exist for them, as it did for us.”

57. What does Mollie Hunter feel about the nature of a good book?

A. It should not aim at a narrow audience.

B. It should not be attractive to young readers.

C. It should be based on original ideas.

D. It should not include too much conversation.www.

58. In Mollie Hunter's opinion, which of the following is one sign of a poor writer?

A. Being poor in life experience.     B. Being short of writing skills.

C. The weakness of description.          D. The absence of a story.

59. What do we learn about Mollie Hunter as a young child?

A. She didn't expect to become a writer.      B. She didn't enjoy writing stories.

C. She didn't have any particular ambitions. D. She didn't respect her teacher's views.

60. What's the writer's purpose in this text?

A. To describe Mollie Hunter's most successful books.

B. To share her enjoyment of Mollie Hunter's books.

C. To introduce Mollie Hunter's work to a wider audience.

D. To provide information for Mollie Hunter's existing readers.
