.
When coal is burned in a boiler, two kinds of ash by-products are produced: a heavy bottom ash and a fine-as-powder fly ash. About 10 to 15 percent of the coal by-product is bottom ash which is used like sand on streets and highways covered with ice, and also on highways as paving material.
It is the fly ash, however, that is receiving much attention. Once considered a waste, fly ash is now regarded as a natural resource in the United States. It can be placed in some lower places, where it is compacted（压实） and covered with soil, for the seeds of various grasses and plants to be placed in the soil to make the land productive.
Fly ash may be added to concrete (混凝土）to build roads and other kinds of buildings, taking the place of the cement(水泥) up to 20 percent. As a by-product of burned coal, fly ash requires no extra energy to be produced, while cement production requires great amounts of energy.
Besides, the technology is able to take out some useful minerals from the fly ash, which is still a very expensive process today. But the time may come when it is cheaper to take out these products from ash than to mine new supplies.
49. The bottom ash can be put on icy streets________.
A. in order to rebuild them          B. in order to make them colorful
C. so that people can walk on them   D. so that cars can run faster
50. The fly ash can be used to________.
A. grow various plants   B. take the place of soil
C. cover productive land       D. make more productive land
51. Which of the following is right?
A. To produce fly ash, some extra coal is to be burned.
B. Fly ash is made while producing cement.
C. It takes less energy to produce fly ash than cement.
D. Fly ash is a costless by-product.
52. The word “mine” in the last sentence of the passage means_______.
A. to buy things from other countries
B. to search for useful materials in the mountains
C. to dig deeply into the ground to get useful materials
D. to take out certain materials from other things

Among the four skills in learning English, which of these is the “Odd-Man-Out”? The answer is speaking. The other three you can do alone on your own. But you can"t really speak alone! Speaking to yourself can be “dangerous” because men in white coats may come and take you away !
Where can you find people to speak English? And how can you practise speaking when you are alone? At school if you pay to go to a language school, you should use the chance to speak .If your teacher asks you to speak in pairs or groups with other students, try to say as much as possible. Don"t worry about your mistakes. Just speak!
Conversation Clubs　Many cities around the world have conversation clubs where people can exchange one language for another . Look in your local newspaper to find a conversation club near you .They are usually free although some may charge a small entrance fee.
Shopping　Even if you don"t want to buy anything ,you can ask questions about products that interest you in a shop. “How much does this cost?” “Can I pay by cheque?” Often you can start a real conversation—and it costs you nothing!
Cafe and Bars　There are often American, Britain, Irish and Australian bars in many large cities .If you can find one, you"ll probably meet many people speaking English as a first or second language.
Language is all around you　Everywhere you go, you find language .Shop names, street names ,advertisements ,notices ,and car numbers....When you walk down the street , practice reading the words and numbers that you see .Say them to yourself .It"s not exactly a conversation ,but it will help you to “think” in English .But don"t speak too loud!
Songs and Video　Repeat the words of an English-language song singing with the music until it becomes automatic. It"s good practice for your memory and for the mouth muscles that you need for English.
Above all, speak as much as possible! Make as many mistakes as possible! When you know that you have made a mistake, you know that you have made progress!

French surgeons have performed what they said on Wednesday was the world"s first partial face transplant--- giving a new nose, chin and lips to a woman attacked by a dog.
Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation.
“The patient is in an excellent state and the transplant looks normal,” the hospitals said in a brief statement after waiting three days to announce the pioneering surgery.
The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are “extremely difficult, if not impossible” to repair using normal surgical techniques, the statement said.
The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to resemble the woman who had been the source of her new face.
The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants,

Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area"s high sensitivity to foreign tissue.
Teams in France, the United States and Britain had been developing techniques to make face transplants a reality
There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers.
Experts say that although such medical advances should be celebrated, the transplant had thrown up moral（道德的）and ethical(伦理的)issues. Little is known about the psychological effect of the transplant.
小题1:The best title for the passage would be ________.

A．French Woman has First Partial Face Transplant

B．First Face Transplant Opens Debate

C．Risks and Ethical Problems of a Face Transplant

D．A Complete Face Transplant of a French Woman

小题2:Why did the woman need such an operation?

A．Her face had been bitten by a dog

B．Her face had been burnt in a fire.

C．She was born especially ugly

D．She wanted to test such an operation.

小题3:The underlined word "resemble" means ________.

A．to remember forever

B．to recognize immediately

C．to set as an example

D．to present similarity or likeness to

小题4:What can we learn about the operation?

A．The woman had used the dead woman" s whole face.

B．There has arisen a debate about the operation.

C．The woman will suffer from psychological damage soon.

D．Such transplants have been performed by doctors.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
What is your favourite colour? Do you like yellow, orange, red? 小题1:Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist（悲观主义者）. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings. 小题2:If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
小题3:. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. 小题4:. A black bridge over the Thames River, near London, used to be the scene of more suicides(自***) than any other bridge in the area---until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
小题5:It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

A．On the other hand, black is depressing.

B．They tell us, among other facts, that we do not choose our favourite colour as grow up --- we are born with our preference.

C．The rooms are painted in different colours as you like.

D．If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.

E. Light and bright colours make people not only happier but more active.
F. Life is like a picture or a poem, full of different colours.
G. Colours do influence our moods---there is no doubt about it.
