It just may be the world’s most costly vacuum cleaner ( 吸塵器). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine.

CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there.

Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere (大氣層) and burn up. But when they do not, it creates big problems.

Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine.

CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction (摩擦) with the air.

Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below.

1.Space junk is created when .

A. unused spacecraft hit each other

B. people in space throw away rubbish

C. a new spaceship is sent up

D. an old spaceship creates friction with the air

2.What’s the danger of space junk?

A. It will pollute space.

B. It will hurt people on the Earth.

C. It will hit a spaceship.

D. It will burn in the atmosphere.

3.Unwanted objects will fall back to the Earth when .

A. they are made to move slowly

B. they meet other objects in space

C. they are not used for years

D. they are near the atmosphere

4.The passage is most probably a .

A. science research paper B. science fiction story

C. newspaper ad D. science news report

I can’t swim so I have a strong fear of water. Look back at my childhood, I think that three reasons might explain fear. Firstly, I am not allowed to go near the water when I was a child, as my mother had an unreasonable fear of it. Therefore, I was taught to see to the water as something danger. Secondly, my eyes became bad when I was five. If I took off my glass in the water, I couldn’t see something, and this increased my fear. What’s worse, for a child I once saw a neighbor drowned. Since then I have been more frightening.

Students usually have two long holidays a year, but have you heard elephants have holidays?

The Indian elephants from a temple are sent on a north-long holiday with massages(按摩) and baths to relax. The 64 elephants will be fed with a lot of food, enough for them to put on 700~800 pounds.

A temple veterinarian said that those Indian elephants would be treated after spending a month walking on roads, living on leaves and bananas and giving shows during lots of temple festivals. Their daily diet includes special rice and other special food, which are very nutritious and can make them healthy and strong. All of these are made by professional people.

This treatment will also calm them down ahead of a busy work schedule in upcoming events later in the year where they are the main attractions. The special holiday has cost the temple about￡12,500, but extra money is ready for being used to treat the animals.

Indians believe that doing something good to elephants can help them get wisdom and power. Having elephants is a traditional symbol of honor for temples across southern India. All temples, however, never buy their elephants. The elephants were donated by people.

1. The Indian elephants can have a __________ holiday.

A. day’s B. week’s C. month’s D. year’s

2.The elephants can do the following during their holiday EXCEPT_____.

A. eating delicious food

B. giving performances

D. having a massage

3. What does the underlined word “nutritious” in Paragraph 3 mean?

A few weeks ago, while I was reading the morning paper, I turned the radio up to listen to a Saturday morning talk show and I heard an old sounding gentleman, with a golden voice. He was telling whoever he was talking with something about “a thousand marbles”.

I was intrigued and stopped to listen to what he had to say …

“Let me tell you something, Tom, something that has helped me keep a good perspective on my own priorities (優(yōu)先考慮的事).”

He continued, “You see, I sat down one day and did a little math. The average person lives for about seventy-five years. Now then, I multiplied 75 by 52 and I came up with 3,900 which is the number of Saturdays that the average person has in their entire lifetime. Now stick with (繼續(xù)傾聽……的話) me, Tom. I’m getting to the important part.”

“It wasn’t until I had lived through over twenty-eight hundred Saturdays that I started thinking about all this in any detail,” he went on. “I got to thinking that if I lived to be seventy-five, I only had about a thousand of them left to enjoy. So I went to a toy store and bought 1,000 marbles. I took them home and put them inside a large, clear plastic container. Every Saturday since then, I have taken one marble out and thrown it away.

“I found that by watching the marbles diminish (變少), I focused more on the really important things in life. There is nothing like watching your time here on this earth run out to help get your priorities straight.

“It was nice to meet you, Tom. I hope you spend time with your family, and I hope to meet you again.”

You could have heard a pin drop on the radio when the old man signed off. I guess he gave us all a lot to think about. I had panned to work that morning. Instead, I went upstairs and woke my wife up with a kiss. “Come on, honey, I’m taking you and the kids to breakfast. And can we stop at a toy store while we’re out? I need to buy some marbles.”

1.The underlines word “intrigued” in Paragraph 2 probably means “ ________”.

A.encouraged B.moved C.worried D.attracted

2.The old man started practicing the theory of “a thousand marbles” ________.

A.in his twenties B.in his fifties

C.in his seventies D.in his eighties

3.What life lesson does this text teach us?

A.Spending more time with our family.

B.Enriching our life with marble games.

C.It’s never too late to love our family.

D.Learning to live life to the fullest.

The word dream is probably heard most frequently from people in show business, where everyone dreams of standing under the spotlight and being somebody. But the truth is that most end up being nobodies. Hong Kong director Derek Yee’s latest film“ I Am Somebody” shows respect for these unknown extras(群眾演員)in the film industry.

In the film, Wan Guopeng, son of a woodcutter, comes a long way from the Northeast with only 1,000 yuan to the dream factory of the East to become an actor. In real life, when the young man was chosen by the director to play the leading role, he had only 20 yuan left but still hadn’t considered giving up.

Famous Hong Kong actor Tony Leung remembered that 30 years ago, he was a salesman but knew that it was not the kind of life he wanted to live. “Wan is exactly like me back then…Only when I was in an acting training course did I realize that what I wanted to be was an actor, not a star winning the best actor awards.”

Yee chose real nobodies to play themselves in the movie. Their strength was their deep understanding of the feelings of the characters they played. But the disadvantage was also obvious: They lacked acting skills. When emotional performances were needed, their expressions and moves seemed unnatural.

The entertainment industry might be the field with the most broken hearts and most efforts gone in vain. Here luck, opportunity and physical appearance are probably much more important than hard work.

In the film, Qin Peijun, a survivor from a coal mine collapse(煤礦坍塌), goes all out to take hold of every possibility to appear in the lens of the camera, even if only as an extra. However, it is obviously much harder for him to realize the dream of becoming a professional actor than for Wang Zhao, who is a lazy bone with a pretty face.

Some critical comments are directed at the sudden inversion(反轉(zhuǎn)) in the last part of the film. The two leading actors’ happy endings seem to disagree with the film’s realistic style. But anyway, this movie is not a documentary but a way to reinforce(硬化) that every brave heart deserves to have their dreams realized.

1. Which of the following can best describe Wan Guopeng?

A. Determined. B. Careful.

C. Intelligent. D. Easy-going.

2.Derek Yee chose real nobodies to play in the film because____.

A. he respected these people

B. they knew well about the characters

C. he needed emotional performances

D. they asked for less money

3.What does the underlined phrase “in vain” in Paragraph 5 mean?

A. Wrongly. B. Secretly.

C. Without success. D. Without consideration.

4.What’s the main idea of this passage?

A. It’s OK to be nobody.

B. It’s really hard to become a successful actor.

C. Live the dreams.

D. Be a person of dreams.
