Planet Hunter
When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets(行星)in other solar(太陽的)systems where life might exist, ”he says. “I decided to try to find planets orbiting(沿…軌道運行)other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995, ”Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it, and our patience paid off. ”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family”of three planets. In June 2002 they announced another discovery: a Jupiter-like(像木星一樣的)planet orbiting star 55 Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55 Cancri is a major breakthrough: it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun.
Why is this important? Scientists think that life on Earth may exist because of two special features(特徵)in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth. ”Dr. Marcy explains. “Without Jupiter, life on Earth would likely have been destroyed. ”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life, can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55 Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life! ”
1.What can we learn about Dr. Marcy from the passage?
A. He is fond of watching Jupiter.
B. He is from a scientist family.
C. He dislikes working with Paul Butler.
D. He is interested in finding life in outer space.
2.Which of the following is true of the recent discovery?
A. The planet is not as protective as Jupiter.
B. The planet is close to star 55 Cancri.
C. The planet proves to be a gas planet.
D. The planet is as large as Jupiter.
3.How many planets orbiting other stars have the two scientists discovered so far?
A. 100 B. 69 C. 66 D. 65
4.Dr. Marcy thinks that life may exist in the 55 Cancri system because ______.
A. he has found the system similar to the solar system
B. he has discovered an Earth-like planet there
C. he has discovered a rocky planet there
D. he has found signs of life in the system
5.“But we stuck with it”(in Paragraph 3)means ______.
A. they felt discouraged
B. they carried on with it
C. they failed in their attempt
D. they made some progress

When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood,he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.
These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence(能力)and came to feel they were worthwhile members of society, ” said George Vaillant, the psychologist(心理学家)who made the discovery. “And because they felt good about themselves, others felt good about them.”
Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.
The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.
Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings(基础)of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”
1.What do we know about John?
A.He received little love from his family.
B.He had few childhood playmates.
C.He enjoyed his career and marriage.
D.He was envied by others in his childhood.
2.Vaillant’s words in Paragraph 2 serve as _______.
A.a description of personal values and social values
B.an analysis of how work was related to competence
C.an example for parents' expectations of their children
D.an explanation why some boys grew into happy men
3.Vaillant's team got their findings by _______.
A.recording the boys' effort in school
B.comparing different sets of scores
C.evaluating the men's mental health
D.measuring the men's problem solving ability
4.What can be inferred from the last paragraph?
A.Competent adults know more about love than work.
B.Emotional health is essential to a wonderful adult life.
C.Love brings more joy to people than work does.
D.Independence is the key to one's success.
