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 in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting 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 planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about 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 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 55Cancri. 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!”What can we learn about Dr. Marcy from the passage?
| A．He is fond of watching Jupiter. |
| B．He is from a scientist family. |

One August afternoon, Richard Allen dropped off his last passenger, Mrs. Carey. Lifting two grocery bags, he followed her across the yard and stood on the step of her house. Glancing up, he saw a large wasp (黄蜂) nest under the roof. Allen had heard that wasps can become more likely to sting (蜇) in summer. He mentioned this to Mrs. Carey, who had opened the door.
“Oh, they don’t bother me,” she said lightly. “I go in and out all the time.”
Anxiously, Allen looked at the nest again—to see the wasps flying straight at him. “Hurry!” he shouted to Mrs. Carey. “Get in!”
She stepped quickly inside. Allen ran for his mini-bus. Too late; they were upon him. Just as he jumped aboard, half a dozen red spots showed on his arm, and he felt more on his back and shoulders.
As he was driving down the road, Allen felt as if something was burning at the back of his neck, and the “fire” was spreading forward toward his face. An immediate anxiety took hold of him. Allen knew that stings could cause some persons to die. But he had been stung the previous summer and the after-effects soon passed. However, what he didn’t know was that the first sting had turned his body into a time bomb waiting for the next to set off an explosion.
Miles from the nearest medical assistance, Allen began to feel his tongue thick and heavy and his heartbeat louder. Most frightening, he felt his breathing more and more difficult. He reached for the radio mike(话筒), trying to call the mini-bus center, but his words were hardly understandable. Signals were also poor that far out. He knew a rescue team was on 24-hour duty at the Amherst Fire Department’s north station. So his best chance was to make a run for it.
Rushing down the mountain, Allen tried not to panic, focusing his mind on each sharp turn. He was almost through the last of them when he felt sure he was going into shock(休克). Just then he reached for the radio mike again.
“Call fire station,” he shouted, concentrating to form the words. “Emergency. Bee sting. Emergency. There in ten minutes.”
“Five-ten.” the center replied. www. .com
Hold on, Allen thought. Keep your eyes open. Breathe. Keep awake.
At last he reached the station. Two firemen ran out. Allen felt their hands grasp him before he hit the ground. You made it, he thought. It is mentioned in the passage that wasps are more likely to attack when_____.
| A．there are huge noises |
| B．strangers are approaching |

| A．he was unable to speak clearly |
| B．his radio equipment was poor |
| C．he was in a state of shock |
| D．no one was on duty |
Which would be the best title for the passage？

| D．War against Wasps |
Ever since Stephanie’s 13th birthday we have been receiving comments from other adults expressing their sympathies because our daughter is now a teenager．We’ve heard everything from，“Sure she’s a good kid，but just wait，now that she’s teenager…”to the ever inspiring，“Well，all kids are rotten when they are teenagers，just try to go through it the best way you can．”What’s more upsetting is that many of these insensitive adults feel the need to share their negative predictions well within the hearing of both our daughters．
I know that teenagers can be moody（闷闷不乐）and difficult at times，but I’m 38 and I can also be difficult and moody．We worry about the future and want today’s kids to know that we care for them and that there are opportunities that wait for them．However, at the very point they set out on that journey toward adulthood we stand there watching them disapprovingly（不赞成），just waiting for them to make mistakes．“just like we knew they would．”We tell them to respect themselves and to say no to drugs，yet we fail to set a positive example by treating them with kindness and consideration，demonstrating（示范）our respect for them．
I have，at times been guilty of this behavior but am now realizing that the more I see each person as a person，the more I am pleasantly surprised in some way or another. For example，a few weeks ago my husband and I were having dinner at our favorite restaurant and two teenage boys came in and sat down right beside us．I must admit that my first thought was，“perfect，there goes our quiet, peaceful dinner．”I was so wrong! These young men were well behaved．quiet and left a nice tip for the waitress．Once I looked beyond the jeans so loose they were practically falling off and the multi-colored hair, I saw what fine people these kids were．
Many of the people who，perhaps unknowingly, treat teens with disrespect are unhappy about the fact that pop singers and sports stars are our children’s heroes. I feel that unless we give them something better to go after, we really shouldn’t complain．When their children reach their teens，parents usually expect_________．
| A．trouble | B．sympathy |
| C．congratulations | D．inspiring comments |
In the author’s opinion，the trouble with parents is that________．
| A．they are too watchful of their teenage children |
| B．they are too concerned about their children’s future |
| C．they fail to treat teenagers with enough kindness and respect |
| D．they speak ill of their children within their hearing |
When two teenagers came into the restaurant and sat beside the author, her first thought was that__________．
| A．they were wrong to have chosen this restaurant for dinner |
| B．something interesting was going to happen over dinner |
| C．her quiet dinner with her husband would be ruined |
| D．she and her husband were going to have a pleasant surprise |
What does the author think of the two teenage boys?
| A．They may become nice people if they are willing to change their lifestyle． |
| B．They are typical of teenagers who wear ill-fitting clothes and dye their hair． |
| C．They’re fine young men despite their loose jeans and multi-colored hair． |
| D．They will respect you if you respect them． |
Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out.” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
“It was a strange-looking machine –one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the center of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen:
“ENTER NAMES VOYAGER 1: … VOYAGER 2: …”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED（自动回收程序已启动）.”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow (光芒), until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION: MARS. RETRIEVE DATE: 2025.”Where did the boy’s father most likely work?
| A．In an electronic factory. |
| B．In a computer company. |
| C．In a scientific research center. |
| D．In an information processing center. |
Mark thought“SPACE TRANSPORTER”on the screen was the name of _________． .
| A．a computer game | B．a company website |
| C．a software producer | D．an astronomy program |
What happened to the boys at the end of the story?
| A．They were blown into the air. |
| B．They were sent to another planet. |
| C．They were hidden in the strong light. |
| D．They were carried away to another country |
Why did Jason want to shut off the computer?
| A．He was afraid of being scolded. |
| B．He didn’t like the loud noise and light. |
| C．He didn’t want to play games any more. |
| D．He was afraid something dangerous might happen. |
If your boss asks you to work in Moscow this year, he’d better offer you more money to do so — or even double that depending on where you live now. That’s because Moscow has just been found to be the world’s most expensive city for the second year in a row by Mercer Human Resources Consulting.
Using the cost of living in New York as a base, Mercer determined Moscow is 34.4 percent more expensive including the cost of housing, transportation, food, clothing, household goods and entertainment(娱乐).
A two-bedroom flat in Moscow now costs $4,000 a month; a CD $24.83, and an international newspaper $6.30, according to Mercer. By comparison, a fast food meal with a hamburger (汉堡包) is a steal at $4.80.
London takes the No.2 place, up from No.5 a year ago, thanks to higher cost of housing and a stronger British pound relative to the dollar. Mercer estimates (估算) London is 26 percent more expensive than New York these days. Following London closely are Seoul and Tokyo, both of which are 22 percent more expensive than New York, while No.5 Hong Kong is 19 percent more costly.
Among North American cities, New York and Los Angeles are the most expensive and are the only two listed in the top 50 of the world’s most expensive cities. But both have fallen since last year’s study — New York came in 15th, down from 10th place, while Los Angeles fell to 42nd from 29th place a year ago. San Francisco came in a distant third at No. 54, down 20 places from a year earlier.
Toronto, meanwhile, is Canada’s most expensive city but fell 35 places to take 82nd place worldwide. In Australia, Sydney is the priciest place to live in and No. 21 worldwide. What do the underlined words “a steal” in Paragraph 3 mean?
| A．an act of stealing | B．something very cheap |
| C．something delicious | D．an act of buying |
London has become the second most expensive city because of ______.
| A．the high cost of clothing |
| B．its expensive transportation |
| C．the stronger pound against the dollar |
| D．the high prices of fast food meals |
Which city is the third most expensive on the list?
| A．Sydney. | B．Hong Kong. | C．Moscow. | D．Tokyo. |
Which city has dropped most on the list in North America?
| A．Toronto. | B．Los Angeles. | C．San Francisco. | D．New York. |
The world is filled with smart, talented, educated and gifted people. We meet them every day. A few days ago, my car was not running well. I pulled it into a garage and the young mechanic had it fixed in just a few minutes. He knew what was wrong by simply listening to the engine. I was amazed. The sad truth is, great talent is not enough.
I am shocked at how little talented people earn. I heard the other day that less than 5 percent of American earn more than $100,000 a year. A business consultant (顾问) who specializes in the medical trade was telling me how many doctors, dentists and people like them struggle financially. All this time, I thought that when those students studying medicine graduated, the dollars would pour in. It was this business consultant who gave me the phrase “They are one skill away from great wealth.” When I ask the classes I teach “How many of you can cook a better hamburger than McDonald’s ?”, almost all the students raise their hands. I then ask, “So if most of you can cook a better hamburger, how come McDonald’s makes more money than you?” The answer is obvious---McDonald’s is excellent at business systems. The reason why so many talented people are poor is that they focus on building a better hamburger and know little or nothing about business systems. The world is filled with talented poor people. All too often, they’re poor or struggle financially or earn less than they are capable of , not because of what they know but because of what they do not know.The example mentioned in the first paragraph is to show ______.
| A．how little talented people earn |
| B．the world is filled with talented people |
| C．he is not good at repairing cars |
| D．the mechanic is good at repairing cars |

The writer seems to believe that _____.
| A．all talented people are not rich |
| B．a person with a talent is sure to become rich |
| C．a talented person is poor just because he knows too much |
| D．many talented people earn little because of something they don’t know |
