A federal agency on Tuesday called for a ban on all cellphone use by drivers -- the most far-reaching recommendation up to now — saying its decision was based on a decade of investigations into distraction-related(與分散注意力有關(guān)的) accidents, as well as growing concerns that powerful mobile devices are giving drivers even more reasons to look away from the road.
As part of its recommendation, the National Transportation Safety Board is urging states to ban drivers from using hands-free devices, including wireless headsets. No state now has made laws to ban such activity, but the Board said that drivers faced serious risks from talking on wireless headsets, just as they do by taking a hand off the wheel to hold a phone to their ears.
However, the concern was heightened by increasingly powerful phones that people can use to send e-mails, watch movies and play games.
"Every year, new devices are being on sale." she said. "People are attracted to update their Facebook page, to play music with cellphone, as if sitting at a desk. But they are driving a car."
The agency based its recommendation on evidence from its investigation of numerous crashes in which electronic distraction was a major contributing factor.
Ms. Hersman said she understood that this recommendation would be unwelcome in some circles, given the number of drivers who talk and text. But she compared distracted driving to drunken driving and even smoking, which required wholesale cultural shifts to change behavior.
"It's going to be very unpopular with some people." she said. "We're not here to win a popularity contest. We're here to do the right thing. This is a difficult recommendation, but it's the right recommendation and it is time."
The agency's recommendation is not required for states to adopt such a ban. And it won't likely be agreed upon by state lawmakers who are unwillingly to anger those who have grown accustomed to using their device behind the wheel.
The ban also deserves attention because it is the first call by a federal agency to end the practice completely, rather than the partial ban that some lawmakers have put in place by allowing hands-free talking.
小題1:The ban on all cellphone use by drivers was put forward______.
A．a(chǎn)fter a long discussion and recommendation
B．a(chǎn)fter about ten years' investigation in it
C．because of the most powerful mobile devices

Supermarket Morrisons today announced to launch an online shopping operation within two years in a move to catch up with its web-savvy rivals. The UK's fourth biggest supermarket said Morrisons.com would offer grocery and non-food products but would take time to build from zero.
As part of its online development, Morrisons - the only one of the "Big Four" grocers to have a significant internet business - revealed it had invested £32 million in a 10% stake of a New York-based online grocer. The announcement came as Morrisons posted a 13% increase in underlying pre-tax profits of £869 million in the year to January 30.
Morrisons is implementing a growth strategy which is focused on expanding its e-commerce business and moving into the convenience store market. It has earmarked £3 billion in investment over the next three years. The supermarket floated the idea of launching its own website last year and today is the first firm commitment to realising that goal.
Last month, the company took its first major step to launching an online operation with the acquisition of internet retailer Kiddicare for £70 million. The company said this move, along with the 10% "strategic" stake in American online grocer FreshDirect announced today, would help it launch its own website in the future. FreshDirect was launched in 2002 and serves 600,000 customers in New York, New Jersey and Connecticut. The deal will see Morrisons chief executive Dalton Philips join the company's board.
Morrisons also revealed it would open three convenience stores, around 3,000 sq ft in size, in July under the name M Local. The shops will be located in Morrisons' heartland in the north of England, in neighbourhoods around the M62 motorway. The company said the convenience business was the second-fastest growing part of the market. Rival models include Tesco Metro and Sainsburys Local.
小題1:FreshDirect severs 600,000 customers in          .
A．ConnecticutB．New JerseyC．New YorkD．certain states
小題2:Which would help Morrisons launch its own wesbsite in the future?
A．Taking measures to beat its rivals as quickly as it could
B．Offering enough grocery and non-food products from zero
C．Building more convenience stores and market in the United States
D．Launching an online operation with the acquisition of interest retailer
小題3:Which of the following would be the best title of the passage?
A．Morrisons Has Many Business Rvials
B．Morrisons Will Launch an Online Operation
C．Morrisons Switches to Run Online Shopping
D．Morrisons Wants to Establish Branches

Modern life is impossible without travelling. The fastest way of travelling is by plane. With a modern airline you can travel in one day to places which it took a month or more to get to hundred years ago.

Many people like to travel by car. You can make your own timetable. You can travel three or four hundred miles or only fifty or one hundred miles a day, just as you like. You can stop wherever you wish where there is something interesting to see, at good restaurant where you can enjoy a good meal, or at a hotel to spend the night.

If you exhibit positive characteristics such as honesty and helpfulness, the chances are that you will be thought as a good-looking person, for a new study has found that the perception （認(rèn)知） of physical attractiveness is influenced by a person's personality．
The study, which was led by Gary W．Lewandowski, has found that people who exhibit negative characteristics, such as unfairness and rudeness, appear to be less physically attractive to observers．In the study, the participants viewed photographs of opposite-sex individuals and rated them for attractiveness before and after being provided with information about their personalities．
After personality information was received, participants also rated the probability of each individual' s becoming a friend and a dating partner．Information on personality was found to significantly change the probability, showing that cognitive （認(rèn)知的） processes modify （修改） judgments of attractiveness．
"Thinking a person as having a desirable personality makes the person more suitable in general as a close relationship partner of any kind," said Lewandowski．
The findings show that a positive personality leads to greater expectation of becoming friends, which leads to greater expectation of becoming romantic partners and, finally, to being viewed as more physically attractive．The findings remained consistent regardless of how "attractive" the individual was formerly thought to be or of the participants' current relationship status．
"This research provides a positive outcome by reminding people that personality goes a long way toward determining your attractiveness; it can even change people's impressions of how good-looking you are," said Lewandowski．
小題1:In the study the participants were required to _____．
A．try to make friends with each other
B．try to prove positive characters make people more attractive
C．exhibit negative characters such as unfairness and rudeness
D．rate one's attractiveness by photos before and after knowing her or his personality
小題2:What's the CORRECT order of how cognitive processes modify judgments of attractiveness?
a．find a person with a positive personality
b．view the person more physically attractive
c．want to make friends with the person
d．want to be his/ her romantic partner
A．a(chǎn)→c→d→bB．d→c→b→aC．c→b→a→dD．a(chǎn)→d→c→b
小題3:Which of the following is WRONG according to the passage?
A．The research reminds people to pay more attention to the personality．
B．Personality can change people's impressions of one's appearance．
C．The judgment of one's attractiveness always stays unchanged．
D．Positive personality may lead to more friends．
小題4:The passage is written in a（n） _____ tone．
A．subjectiveB．objectiveC．scepticalD．negative

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（機(jī)制） - like those used on coupon（優(yōu)惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.
Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.
Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.
“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”
Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.
Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential（連續(xù)的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.
“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.
小題1:It can be learned from the text that ______.
A．the short time horizon is the reason why group-buying has been successful.
B．a(chǎn) simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up.
C．a(chǎn) sequential mechanism allows a herding effect which boosts the confidence of the buyers.
D．researchers at the University of Toronto's Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop.
小題2:The underlined word “eliminates” in paragraph 7 probably means“______”.
A．to become or to make something greater in amount, number, value
B．to remove or get rid of something
C．to deliberately not include something in what you are doing or considering
D．to make something known to somebody
小題3:What can be the best title for the passage?
A．Secret for marketing success – boosting confidence.
B．Secret for group-buying mechanism—herding effect.
C．Comparison between a simultaneous mechanism and a sequential mechanism.
D．What others do influences our decisions.
