Since people first sent rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spaceship. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.
Some things we send into space fall back toward the earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.
But space junk falling on housetops (屋頂) is not the biggest worry. Scientists are concerned about what happens when an empty rocket strikes another while orbiting (繞軌道飛行) the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.
So what can be done to clean up the space around our planet? Marco Castronuovo, an Italian researcher, talks about sending a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the atmosphere.
Mr. Castronuovo has proposed (提議) using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite would jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.
Scientists have been concerned about space junk for many years. Right now, the costs of the clean-up have been too great. Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.
【小題1】Much of the space junk _____.

A．was thrown by the astronauts
B．is from broken spaceship
C．is made up of small pieces of things
D．returns to the earth piece by piece
【小題2】Scientists are most worried that the space junk _____.
A．will stop the future space vehicles
B．will do harm to the atmosphere
C．will fall on the housetops
D．will burn up in space
【小題3】What does Marco Castronuovo think of his system?
A．It can remove space junk completely.
B．It can save a large amount of money.
C．It can create a large amount of space.
D．It can develop robotic technology.

科目：高中英語(yǔ) 來(lái)源：四川省成都樹(shù)德協(xié)進(jìn)中學(xué)2010屆高三考前沖刺考試英語(yǔ)試題 題型：閱讀理解


Supermarkets are trying out new computers that make shopping carts more intelligent(具備智能的). They will help shoppers find paper cups or toilet soap, and keep a record of the bill.
The touch-screen devices(觸摸屏裝置) are on show at the Food Marketing Institute’s exhibition here this week, “These devices are able to create value and get you around the store quicker,” said Michael Alexander, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.
Canadian stores will test the Concierge in July. A similar device, IBM’s “Shopping Buddy”, has recently been test-marketed at Stop & Shop stores in Massachusetts.
Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.
“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexander. “They’re not watching 30-second TV ads anymore.”
People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system(系統(tǒng)) that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.
The device also keeps a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.
The new computerized shopping assistants don’t come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.
1. The underlined word “they” (paragraph 1) refers to ______.
A. supermarkets  B. shop assistants    C. shopping carts           D. shop managers
2. Which of the following is the correct order of shopping with computerized shopping carts?
a. Start the system.                                               b. Make a shopping list.
c. Find the things you want.                                  d. Go to a self-checkout stand.
A. abdc                            B. bacd                        C. acbd                        D. bcad
3. We can learn from the last paragraph that ______.
A. intelligent shopping carts cost a large sum of money
B. the Concierge is cheaper than the Buddy devices
C. shop assistants with computer knowledge are well paid
D. average stores prefer the Concierge to the Buddy devices
4. What might be the most suitable title for the text?
A. New age for supermarkets                 
B. Concierge and Shopping Buddy
C. New computers make shopping carts smarter            
D. Touch-screen devices make shopping enjoyable

科目：高中英語(yǔ) 來(lái)源：2010年普通高等學(xué)校招生全國(guó)統(tǒng)一考試（重慶卷）模擬考試英語(yǔ)試卷 題型：閱讀理解


The energy crisis (危機(jī)) has made people aware of how the careless use of the earth’s energy has brought the whole world to the edge of disaster. The over – development of motor transport, with its increase of more cars, more traveling, has contributed to the near – destruction of our cities and the pollution not only of local air but also of the earth’s atmosphere.
Our present situation is unlike natural disasters of the past. Worldwide energy use has brought us to a state where long – range planning is vital. What we need is not a continuation of our present serious state, which endangers the future of our country, our children, and our earth, but a movement forward in order to work rapidly and effectively on planetary problems.
This country has been falling back under the continuing exposures of loss of morality (道德) and the revelation (揭露) that lawbreaking has reached into the highest place in the land. There is a strong demand for morality to turn for the better and for some devotion that is vast enough and yet personal enough to enlist the devotion of all. In the past it has been only in a way in defense of their own country and their own benefits that people have been able to devote themselves wholeheartedly.
This is the first time that we have been asked to defend ourselves and what we hold dear in cooperation with all the other people of this planet, who share with us the same endangered air and the same endangered oceans. There is a common need to reassess our present course, to change that course and to employ new methods through which the world can survive. This is a priceless opportunity.
To grasp it, we need a widespread understanding of nature if the crisis we and the world are facing is no passing inconvenience, no by-product（副產(chǎn)品）of the ambitions of the oil – producing countries, no environmentalists’ only fears, no byproduct of any present system of government. What we face is the result of the invention of the last four hundred years. What we need is transformed life style. This new life style can flow directly from science and technology, but its acceptance depends on a sincere devotion to finding a higher quality of life for the world’s children and future generation.
1. Which of the following has nearly destroyed our cities?
A. The loss of beliefs and ideas.                        B. More of law – breaking.
C. Natural disasters in many areas.                     D.  The rapid growth of motors.
2. By comparing past problems with present ones, the author draws our attention to the        .
A. seriousness of this crisis                                B. ineffectiveness of laws
C. similarity of the past to the present          D. hopelessness of the situation
3. Which of the following is used as an example to show the loss of morality?
A. Disregard for law.                                        B. Lack of devotion.
C. Lack of understanding.                                 D. Destruction of cities.
4. The author wrote the passage in order to        .
A. make a recommendation for a transformed life style
B. limit ambitions of the people of the whole world
C. demand devotion to nature and future generation
D. encourage awareness of the decline of morality

Students and Technology in the Classroom
I love my blackberry—it’s my little connection to the larger world that can go anywhere with me . I also love my laptop computer ，as it holds all of my writing and thought .Despite this love of technology ,I know that there are times when I need to move away from these device and truly communication with others.On occasion ,I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas .Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom ,I have a rule —no laptop ,ipads ,phones ,etc .When students were told my rule in advance of the class, some of them were not happy .
Most students assume that year reasons for this rule include unpleasant experiences in the past with students misusing technology . There’s a bit of truth to that.Some students assume that I am anti-technology . There’s no truth in that at all . I love technology and try to keep up with it so I relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas . I want students to think differently and make connections between the course the material and the class discussion .
I’ve been teaching my history class in this way for many years and the educations reflect student satisfaction with the environment that I create .Students realize that with deep conversation and challenge , they learn at a level that helps them keep the course material beyond the classroom .
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change ,I’m sticking to my plan. a few hours of technology-free dialogue is just too give up.
【小題1】
some of the students in the history class were unhappy with____

A．the course materialB．others’ misuse of technology
C．discussion topicsD．the author’s class regulator
【小題2】
the underlined word “engage ”in para.4 probably means ____
A．exploreB．a(chǎn)cceptC．changeD．reject
【小題3】
according to the author ,the use of technology in the classroom may ____
A．keep students from doing independent thinking
B．encourage students to have in-depth conversations
C．help students to better understand complex themes
D．a(chǎn)ffect students’ concentration on course evaluation
【小題4】
