　　阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
　　Soon it may be harder to stop and smell the roses.
　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
　　The report was recently published in the journal,Atmospheric Environment.
　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.
　　"It's something that is really worthwhile paying attention to."
　　56.What's the passage mainly about?
　　　A.How greatly air plooution affects our lives.
　　　B.Effects of air pollution on bee populations.
　　　C.Measures to fight air pollution.
　　　D.The rapid decline of bee populations in the world.
　　57.According to the passage,Jay Evans probably agrees that ______ .
　　　A.bees are the insect that suffers most from air pollution
　　　B.bees are at risk of dying out owing to air pollution
　　　C.the fading smell of flowers doesn't affect bees so greatly as was thought
　　　D.as is often the case,bees fail to locate the flowers because of the missing scents
　　58.The word"exacerbate" in the last paragraph but one probably means ______.
　　　A.worsen B.improve C.get rid of D.decrease
　　59.Which of the following is NOT true according to the passage?
　　　A.The more air pollution there is in a region,the greater the destruction of the flower scents.
　　　B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.
　　　C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.
　　　D.Air pollution does more harm to insects such as bees and butterflies than human beings.

When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.
Underwater archaeology __the study of ships, aircraft and human settlements that have sunk under large bodies of water is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment .Besides the Swedish ship wreck(残骸）,underwater archaeologists have made more exciting discoveries such as the  5000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world’s knowledge of history, but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines(挖掘机）often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.
【小题1】What purpose does Paragraph 1 serve in the passage?

We often talk about ourselves as if we have permanent genetic defects(缺陷) that can never be changed. “I’m impatient.” “I’m always behind.” “I always put things 　　1 !” You’ve surely heard them. Maybe you’ve used them to describe　　　 ___2　 .

These comments may come from stories about us that have been 　3　 for many years—often from 　4　 childhood. These stories may have no 　5　 in fact. But they can set low expectations for us. As a child, my mother said to me, “Marshall, you have no mechanical (操作机械的) skills, and you will never have any mechanical skills for the rest of your life.” How did these expectations　 6　 my development? I was never 　7　 to work on cars or be around　 8　 . When I was 18, I took the US Army’s Mechanical Aptitude Test. My scores were in the bottom for the entire nation!

Six years later,　 9　 , I was at California University, working on my doctors degree. One of my professors, Dr. Bob Tannbaum, asked me to write down things I did well and things I couldn’t do. On the positive side, I　 10　 down, “research, writing, analysis, and speaking.” On the　 11　 side, I wrote, “I have no mechanical skills.”

Bob asked me how I knew I had no mechanical skills. I explained my life 　12 and told him about my 　13　 performance on the Army test. Bob then asked, “　 14　 is it that you can solve 　 15　 mathematical problems, but you can’t solve simple mechanical problems?”

Suddenly I realized that I didn’t 　16　 from some sort of genetic defect. I was just living out expectations that I had chosen to 　17　 . At that point, it wasn’t just my family and friends who had been　 18　 my belief that I was mechanically hopeless. And it wasn’t just the Army test, either. I was the one who kept telling myself, “You can’t do this!” I realized that as long as I kept saying that, it was going to remain true. 　19　 , if we don’t treat ourselves as if we have incurable genetic defects, we can do well in almost 　20　 we choose.

　　Build the highway and watch the town grow.At first a few shops appear and maybe a restaurant.Then a hotel opens. Eventually new house are built. A village is born.
　　This is also how the virtual world has developed. Think of the Internet as the road carrying information between two computers.Think of the World Wide Web as the village. At first it is just a place on the virtual road where travelers meet. More travelers come bringing new kinds of information. New travelers come bringing new kinds of information.New villages are started.
　　Every willage has a founder.Tim Berners-Lee is the man who wrote the software programme that led to the foundation of the Word Wide Web.How did he get the idea? He tells us on his own web site. "One of the things computers were not able to do was store in formation from different sources. The dream behind the Web is of a common space in which we communicate by sharing information."
　　In 1991 his programmmes were placed on to the Internet.Everyone was welcome to use them.
　　Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programmes he invented. Or he could have joined another company. But in his view the Web is a language,not a pproduct. Charging a gee for using his programmes would have slowed the growth of the Web.And other companies would make similar products to compete. Instead of one World Wide Web there would be several smaller Webs. Each would use incompatible (不相容的) software. They Web is valuable because it uses a common computer language to reach people and share information. Competing webs would lose this value.Imagine if somebody sent you a bill every time you spoke a world of English.
　　In 1994 Tim Berners-Lee formed the World Wide Web Consortium,or W3C.More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone, no matter what their equipment or solftware,can work equally on the Web.
　　"The Web can help people to understand the way that others live and love. It helps us understand the humanity of people," he says.
　　68.The writer's purpose in writing the first two paragraphs is to ______.
　　　A.give us some idea of the Internet
　　　B.give us some idea of the Web
　　　C.tell us how the idea of Web started
　　　D.tell us the idea of the Web is wonderful
　　69.Tim Berners-Lee invented the World Wide Web in order to _____
　　　A.place his programmers on the Internet
　　　B.stop smaller webs appearing
　　　C.help people to form a web site
　　　D.let people share all kinds of information
　　70.According to the text,the disadvantage of competing webs is that they would ______.
　　　A.slow the development of the Web
　　　B.destroy the whole web system
　　　C.lose the value of information
　　　D.waste a lot of money

Most 23-year-olds have not done enough in life to be worthy of having their own documentary（纪录片）
　　Most 23-year-olds aren't LeBron James.
　　The NBA superstar, who recently won gold at the Beijing Olympics, has just released More Than a Game. It is a documentary that follows his rise to stardom (明星地位) and how he and four childhood friends overcame long odds to win a national championship in high school.
　　Combining footage (镜头) taken during James' career at St. Vincent-St. Mary High School in Akron, Ohio, US, along with one-on-one interviews by writer/director Kris Belman, home videos, and personal family photographs, the film is about much more than basketball. At its core (核心) is a story of friendship, loyalty and love.
　　"We set out with a goal as kids and we wanted to accomplish that someway, somehow by using basketball as a tool, not knowing that it was going to create other opportunities for us," James said. "We didn't know it was going to create a brotherhood and trust. We grew from kids into young men."
　　While James is the star, his former teammates, Dru Joyce III, Sian Cotton, Willie McGee and Romeo Travis, play a major role in the film.
　　Their journey began together as 8-year-old boys, winds through years traveling all over America playing in basketball tournaments and finishes in their senior season at St. Vincent-St. Mary High School.
　　At the time, Belman was a college film student. He set out to film James and his friends' season as his final school project, a 10-minute documentary. But after gaining the trust of the players and coach Dru Joyce, Belman spent two months filming and eventually teamed with producer Harvey Mason Jr to the full-length feature.
　　James hopes the film will inspire youngsters (年轻人).
　　"We set out with a goal when we were eight and we accomplished it when we were 18," he said. "It's a great story and I wanted to get it out to kids that have a dream, that they should continue to go after it, believe in it and live it if they want to accomplish something."
