While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol related danger: drunken pedestrians.

Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more frequently-and with higher blood alcohol levels-than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood alcohol level of at least 0.10-which by law in most states signifies intoxication-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 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, 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 Bloomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.

Bloomberg, 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(TRB)  in Washington in January.

Pedestrian accidents have not received enough attention in the past, according to Kay Culprits, who chairs the board’s committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified about how to prevent disasters.

While the rest of the world carried on cycling during the 1950s and 1960s ,America forgot how; even high-school children would drive to school .Recently there has been something of a renaissance(复兴) in cycling, and in many areas it is a very useful way of getting around, especially where bike paths or bike routes have been built. You may well want to buy , hire or borrow a bike. 

     There are two important consequences (后果)of this earlier drop in cycling in the U.S.A. One is that many people do not to know how to cycle. That is, cyclists often behave more like Pedestrians(行人)than motorists: they ride on the sidewalk or on the wrong side of the road; they don't care for stop signs or traffic lights; they ride without lights at night; they give no hand signals .The other consequence is that cycling is regarded by many people not so much as a way of getting from one place to another but as a way of life, a form of exercise, etc. As a result, a large number of young Americans have ten-speed racing bikes. These are very high and fast and great if you are cycling long distances, riding up mountains or racing. At first , though, you may find them awkward (使用不便)for cycling in town. Sight-seeing or shopping ----they are expensive, uncomfortable and hard to control until you get used to them, and unsuitable for rough stony roads.

     There are also ordinary bikes around. If you get hold one of these ,you may find that brakes work by pedaling(踩踏板)backwards. This is perhaps safer than ordinary brakes when it is wet, but it seems to be less effective. This arrangement also means you can't pedal backwards in order to get the pedals in the right place for getting on or moving off.

68.   The passage gives us a brief introduction to _______________________.

     A. advantages of bikes                B. cycling in America

     C. American transportation            D. how to ride a bike

69.   Young Americans prefer racing bikes because they_________________.

     A. can help keep fit                    B. are easy to learn

     C. are safer to ride                     D. are expensive and popular

70.   Which of the following does NOT result from the early drop in cycling in the U.S.A?

     A. Cyclists do not care for traffic lights.

     B. People ride on the wrong side of the roads.

     C. Cycling is not considered a way of transportation.

     D. People have to pedal backwards to stop the bike.

A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday.

Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe（预订） to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost.

Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes.

The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted（转变） from slower-speed, dial-up Internet access while the other half of families had no prior access.

"The industry continues to chip （击破）away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's going to be applications that make the Internet more similar to pay-TV," he predicted.

What does the underlined word “holdouts” in the first paragraph most probably mean?

A. some American families      

B. those who hold out one’s opinions

C. those who have been surveyed    

D. those who still haven’t access to the Internet currently

Many potential customers refuse to subscribe to the Internet mainly because __________.

A. they show too much concern about the cost

B. they can find little value of it

C. they do most YouTube-watching at work

D. the Internet doesn’t reach their homes

From the passage we can infer that _____________.

A. It is not an easy job to transform those holdouts into the Internet users

B. people will adopt dial-up Internet access no more

C. many Americans enjoy doing e-commerce shopping at home

D. more than half of the population are using the Internet in 2005

According to John Barrett, what is the key to attracting more U.S. families to broadband service?

A. making the Internet look more similar to TV set

B. applying the Internet more to entertainment

C. providing more pay-TV programs

D. chipping away at the core of non-subscribers

Which is the best title for the passage?

A. Web develops with technology

B. The present situation of web

C. Many Americans see little point to web

D. It is urgent to promote web service

A couple of years ago,before a trip to China,Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.

“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,”said Davis.

Known as the “Iron Hammer” for her punishing spikes(扣球),Lang made it possible for China to dominate in the sport in the early 1980s.She was a key player on China’s 1984 Olympic gold medal winning team.

When the US team arrived for the Olympics,Lang,48,who is from Beijing,had to take a different route to avoid a crowd of reporters and fans.

Then came the greatest moment to Lang：While the US team was playing in a packed gym,at least 8,000 Chinese fans unfurled an American flag.

“That really says it all,” Davis said.“They look at her as an icon(偶像)．I’m sure it’s hard for them to see her coaching another country,but they love her so dearly that her success is their success.”

The loyalty of the Chinese fans was tested on Friday,when China lost a match to the US.

“It’s a pity that China lost the match,but I’m still glad that Lang Ping’s team won,since she is the pride of China’s volleyball,” said Liu Chengli,a spectator.“We also cheered for

Lang’s victory.”

Lang said she just tried to stay professional when the two teams meet.“It doesn’t matter if we play China or any other team.It’s the same.” Lang said.

Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players,said US volleyball player Lindsey Berg.

“It’s such an honor to be here and play for our coach here in China,”she said.“The amount of support that the Chinese give to her and us has been tremendous.The whole event has been unbelievable.”

       A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”．This idea is dangerous．

       Science can be a force for evil as well as for good．Its applications can be channeled either way, depending on our decisions．The decisions we make, personally or collectively, will determine the outcomes of science．But here is a real danger．Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference．And, rather than fighting for the best possible policies, we may step back and do nothing．

       Some people go even further．They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime．They believe that science will get out of control in the end．This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world．

       In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science．Without a common understanding, the challenges of “controlling” science in this century will be really tough．Take human cloning for example．Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques．The outcomes are hard to predict．

       Therefore, discussions on how science is applied should be extended far beyond scientific societies．Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future．

What can we conclude from the recent study?

       A．People think highly of science．

       B．People hold mixed opinions about science．

       C．Science is getting dangerously out of control．

       D．Science is used for both good and bad purposes．

According to the passage, what will happen if we hold that science is getting beyond control?

       A．The development of science will hopelessly slow down．

       B．Businesses will have even greater influence on science．

       C．The public will lose faith in bringing about a bright future．

       D．People will work more actively to put science under control．

The discussion should reach beyond scientific societies because __________．

       A．scientists have failed to predict the outcomes

       B．the ties between different areas need strengthening

       C．united efforts are necessary for the development of science

       D．people need to work together to prevent the bad use of science

What is the main idea of the passage?

       A．Science and its applications bring us many dangers．

       B．The development of science mostly lies in people’s attitudes．

       C．Mankind can largely take control of science with their efforts．

       D．The future of science will be influenced by the dangerous ideas．
