Crying babies,buzzing mosquitoes,ringing car alarms,they're all annoying noises. But what's the worst? A recent survey lists the things we hate to hear.
However,numberone on the list was the sound of a dentist's drill. "That lust sends shivers down my spine ," said one respondent. " After a visit to the dentist,I sometimes wake up at night with that sound in my head. It's horrible," said another. " I've seen patients shaking with fear when I bring out the drill," explained a dentist. Of course,anyone who has actually been to the dentist and heard the sound will probably agree with that.
But there's some good news,a new device developed by experts at College London,Brunei University and London South Bank University can cancel out the sound of the frightening drill. The tiny machine allows patients to listen to music on an MP3 player while the sound of the drill is eliminated. However,patients are still able to hear the dentist's voice because not all sounds are filtered out (滤除) .
The theory behind it is fairly straightforward. Microphones are placed close to the dental drill. These pick up any sounds and transform them into digital signals. Then,electronic filters cancel out any unwanted sound waves. This can be done even if the wave's amplitude (振幅) and frequency changes. However,the great thing is that this technology also allows other noises,such as the dentist's voice to come through.
It's easy to use,too. Patients simply plug the soundfiltering machine into their MP3 players. Then,via headphones,they can listen to music and hear the dentist's voice without being disturbed by the noise of the drill. Fantastic！
So,next time you go to the dentist,remember to bring your MP3 player.

5. B主旨大意题。全文介绍了一项新科技产品，能让患者听音乐的同时不受牙医电钻的干扰，故答案为B项。
6. D词义推断题。由第2段第一、三句可知：我们最害怕听到的声音排名第一的就是牙医的电钻。一名患者说在看过牙医后，他经常夜里醒来脑袋里都是电钻的可怕声音。故答案为D 项，意为牙医电钻的声音让人毛骨悚然。
7. C细节理解题。由第四段第四句可知，电子滤波器过滤掉不必要的波声。由后文可知，该设备在声波振幅和频率改变的情况下，依然可以过滤掉不必要的波声，同时还能让牙医的声音通过。故答案为C项。
A、D项与原文的表述矛盾，B项错误在于把声波转换成数字信号的是麦克风，而不是该设备。

LIMA. Peru―Nearly 60 years after Thor Heyerdahl's Pacific Ocean crossing aboard the balsa(白塞木) raft Kon-Tiki,a Norwegian team is in Peru putting final touches on a new boat to repeat the journey.
"I think we are mentally prepared and we are really,really anxious to put this raft in the ocean," said Olav Heyerdahl,28, the adventurer's grandson and one of the sixmember crew.
Behind him in a dry dock in Lima's port of Callao was the raft Tangaroa―named for the Polynesian god of the ocean―which is scheduled to set sail April 28.
The expedition had been set for last year,but was postponed after key sponsors shifted funds to help victims of the 2004 Southeast Asian tsunami.
In 1947,Thor Heyerdahl and his team sailed their simple raft 5 ,000 miles from Peru to Polynesia in 101 days to support Heyerdahl's theory that the South Sea Islands were settled by ancient mariners from South America. Heyerdahl,who died in 2002 at age 87,documented his voyage in the bestselling book Kon-Tiki and in an Oscarwinning documentary film.
The adventurer's 67-year-old son,Thor Heyerdahl Jr.，came to Peru to see the new boat and cheer on his own son. "Fm very happy for him that he gets this opportunity," he said.
The new 56-foot boat is larger than the Kon-Tiki,with eight crossbeams fastened to 11 balsa logs from Ecuador and covered by a bamboo deck.
The Kon-Tiki carried only the most basic equipment,even by 1947 standards. But the Tangaroa features abundant modern technology,including solar panels to produce electricity and satellite navigation and communications gear. "We have seen this project grow from just an idea,a dream,and then suddenly you are 10 days away from being on the raft on the sea”， said Swedish filmmaker Anders Berg,who will document the journey. " It's like pregnancy,I would say."
The Kon-Tiki was equipped with a simple sail and could not navigate against the wind. Its journey ended when it sank on a reef near Tahiti.
The expedition is a $800,000 venture backed by the Norwegian Environment Ministry,private businesses and Heyerdahl's hometown of Larvik,Norway.
( ) 1. The Norwegians will have the journey to .
A. support some theories B. repeat an old voyageC. explore some new places D. test a new kind of boat
( ) 2. What does the underlined sentence "It's like pregnancy" mean in the passage?
A. They have prepared for a long time.
B. The journey is common.
C. A baby will be born during the journey.
D. The journey will be hard.
( ) 3. Which of the following statements is true according to the passage?
A. Tangaroa was sunk on a reef near Tahiti.
B. The journey was delayed because of some financial reasons.
C. The voyage by Thor Heyerdahl was documented by an American filmmaker.
D. Six people will take part in the journey including Thor,s grandson,a filmmaker.
( ) 4. What is the best title for the passage?
A. Thor Heyerdahrs Pacific Ocean Crossing
B. Norwegians to Recreate Kon-Tiki Journey
C. An Oscarwinning Documentary Film
D. An Unforgettable Journey

The tomato is the world's most popular fruit. And yes,just like the eggplant and the pumpkin,botanically speaking it is a fruit,not a vegetable. More than 60 million tons of tomatoes are produced per year,16 million tons more than the second most popular fruit,the banana. Apples are the third most popular (36 million tons) ，then oranges (34 million tons) and watermelons (22 million tons) .

Furthermore,new medical research suggests that the consumption of lycopene―the stuff that makes tomatoes red―may prevent cancer. As with essential amino acids (氨基酸) ，they are not produced by the human body. Lycopene is the most powerful part in the carotenoid (类胡萝卜素) family and,with vitamins C and E,protect us from the free radicals that degrade many parts of the body.
The scientific term for the common tomato is lycopersicon lycopersicum,which mean "wolf peach". It is a cousin of the eggplant,red pepper,ground cherry,and potato,also known as the nightshade (颠茄) or solanaccae. There are more than 10 ,000 varieties of tomatoes.

The long years of food shortage in this country have suddenly given way to obvious abundance. Stores and shops are choked with food. Yet,instead of joy,there is widespread uneasiness and confusion. Why do food prices keep on rising,when there seems to be so much more food about? Is the abundance only temporary,or has it come to stay? Does it mean that we need to think less now about producing more food at home? No one knows what to expect.
The recent growth of export surpluses (过剩) on the world food market has certainly been unexpectedly great,partly because of two strange successful grain harvests. North America is now being followed by a third. Most of Britain's overseas suppliers of meat,too,are offering more this year and home production has also risen.
But the effect of all this on the food situation in this country has been made worse by a rise in food prices,due chiefly to the gradual cutting down of government support for food. The shops are overstocked with food not only because there is more food available,but also because people,frightened by high prices,are buying less of it.
Moreover,the rise in domestic prices has come at a time when world prices have begun to fall,with the result that imported food,with the exception of grain,is often cheaper than the homeproduced variety. And now grain prices,too,are falling. Consumers are beginning to ask why they should not be enabled to benefit from this trend.
The significance of these developments is not lost on farmers. The older generations have seen it all happen before. Despite the present price and market guarantees,farmers fear they are about to be pressed between cheap food imports and a shrinking home market. Present production is running at 51 percent above prewar levels,and the government has called for an expansion to 60 percent by 1956;but repeated Ministerial advice is carrying little weight and the expansion programme is not working very well.
( ) 1. Why is there " widespread uneasiness and confusion”about the food situation in Britain?
A. The abundant food supply is not expected to last.
B. Britain is importing less food.
C. Despite the abundance,food prices keep rising.
D. Britain will cut back on its production of food.
( ) 2. The main reason for the rise in food prices is that .
A. people are buying less food
B. the government is providing less financial support for agriculture
C. domestic food production has decreased
D. imported food is driving prices higher
( ) 3. The government's expansion programme didn't work very well because .
A. farmers were uncertain about the financial support the government guaranteed
B. farmers were uncertain about the benefits of expanding production
C. farmers were uncertain about whether foreign markets could be found for their produce
D. the older generation of farmers were strongly against the programme
( ) 4. What did the future look like for Britain's food production at the time this article was written? ^
A. The fall in world food prices would benefit British food producers.
B. An expansion of food production was at hand.
C. British food producers would receive more government financial support.
D. It looks depressing despite government guarantees.

While drunken driving may be on the decline,traffic safety experts remain puzzled over how to deal with another alcoholrelated danger：drunken pedestrians.
Pedestrians struck and killed by cars often are extremely drunk. In fact,they are drunken more frequently―and with higher bloodalcohol levels―than drunken drivers who are killed in accidents,various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a bloodalcohol level of at least 0. 10―which by law in most states signifies intoxication (醉酒) 一compared to only 25 percent of drivers in deadly accidents,according to recent federal data.
Some types of pedestrian accidents have been declining nationally,especially those involving children,but the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2 ,500 a year. The total number of pedestrians killed annually in US traffic accidents is at least 7 ,000,or one of every seven highway accidents resulting in death.
"We're dealing here,we think,with a very severe drinking problem that leads to a severe highway safety problem”，said Richard Blomberg,president of Dunlap and Associates Inc.，in Norwalk,Coon.
Blomberg,whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans,was among several researchers who spoke on the topic at the annual meeting of the Research Council's Transportation Research Board (TRE) in Washington in January.
Pedestrian accidents have not received enough attention in the past,according to Kay Colpitts,who chairs the board's committee on pedestrians. Few methods exist to monitor walking habits,she said,and researchers have been puzzled about how to prevent disasters.
( ) 5. Which of the following would be the best title for the passage?
A. Traffic Safety.
B. Drunken Drivers.
C. Drunken Pedestrian Accidents.
D. A Severe Highway Safety Problem.
( ) 6. Among the causes of walkers' accidents,the most serious problem is .
A. long delays in traffic signals causing pedestrians to lose patience
B. taking too much alcohol and then hanging along the roads
C. a lack of adult keeping eyes on many children involved in accidents
D. former drunken drivers whose licenses are not allowed to use for a time
( ) 7. According to recent federal data,drunken drivers with an over 0. 10 bloodalcohol level in deadly accidents .
A. are 15 percent less than drunken adult walkers
B. are relatively steady at 2 ,500 a year
C. are at least 7 ,000 in US traffic accidents
D. make up oneseventh of highway accidents
( ) 8. From the passage we know that Blomberg is .
A. a researcher
B. a specialist in traffic safety
C. a clerk of a consulting company
D. a government official
