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(与分散注意力有关的) 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.The ban on all cellphone use by drivers was put forward______.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.The text mainly discusses the relationship between .
| A．heart problems and air quality |
| B．heart problems and exercising |
| C．heart problems and smoking |
| D．heart problems and fatty food |
The underlined word “modest” in Paragraph 3 most probably means.
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
What can we learn from the text?
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking, |
| D．Stricter regulations on pollutants should be made. |
When he wrote The Adventures of Tom Sawyer and The Adventures of Huckleberry Finn, Mark Twain turned to Hannibal. The relationship between Hannibal and Twain began in November 1839, when Twain’s father decided to leave the village in Florida and move east about 35 miles to the somewhat larger and more prosperous Hannibal, on the banks of the Mississippi River. Twain marked his fourth birthday about a week after the family settled there. He showed little promise of becoming a long-term resident. However, because his health was so poor that his parents probably feared he would not survive childhood.
During the family’s first few years in Hannibal, Twain was too young to understand fully the changes going on around him. About the time the family moved into their new home. Twain’s health improved a lot. Instead of having to lead a quiet indoor life, he could roam the streets of Hannibal. Climb the surrounding hills, explore the area’s caves and splash about in local swimming holes. He reveled in his newfound freedom, spending nearly all his free time playing outdoors with the other boys in town and soon becoming a leader.
Twain’s carefree days did not last long, on March 24, 1847, his father died. For the next six years, his brother Henry, and his sister Pamela lived with their mother in the family home. Twain began taking odd jobs after school to bring in extra money. Within a year of his father’s death, he quit school and became an apprentice (学徒) printer, and when his brother Orion bought the Hannibal Journal in 1851, Twain went to work for him as a printer and editorial assistant. The stories he wrote for Orion’s paper, his first publications, taught him that he much preferred writing to typesetting. Thus, when he decided to leave Hannibal in May 1853, he already had an idea of his future career. Why did little Mark Twain move and live in Hannibal?
| A．Because he wanted to live in a larger and more prosperous city. |
| B．Because his father brought him there. |
| C．Because he wanted to wrote his novels there. |
| D．Because he wanted to become a long-term resident of Hannibal. |
When did Mark Twain become healthy?
| A．As soon as he arrived in Hannibal. |
| B．At the time when his family moved into their old home. |
| C．After his father died. |
| D．At the time when his family moved into their new home. |
The last paragraph mainly tells us _________.
| A．the happy childhood of Mark Twain |
| B．how Mark Twain became a famous writer |
| C．how Mark Twain to earn money to support his family |
| D．why Mark decided to leave Hannibal |
The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year，but it’s always on a Sunday.

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备） to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgrum. Her services were recognized in the form of a Military’s Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work.

Accidents and illness are unhappy things to talk about, but no one can expect to live a lifetime without having some kind of accident or becoming ill. Some accidents and illnesses are serious and may result in long periods of invalidism.
The newspapers contain spectacular accounts of accidents in the street and highways and public places, but nearly as many accidents occur around the home. Somebody trips on a rug. Somebody falls off a stepladder. Somebody is careless in cooking dinner, and is burned. Accidents incurred in the playing of sports and swimming also accounts for a large number of injuries, big and little. Despite constant campaigns to reduce the number of accidents, there are still approximately 100,000 accidental deaths and nearly 9,000,000 nonfatal injuries in the United States each year.
It has been estimated that around 3,000,000 people are constantly ill in the United States throughout the year and that over half the illness is caused by respiratory diseases, chiefly colds and influenza.
The pain and suffering caused by accidents and illness tell only half the story. Loss of time from school and work and medical and hospital expenses often make the pain seem worse. Money spent in this country for doctors, services, hospitalization, nursing care, drugs, medicines, Xrays, and special treatments, amounts to a huge annual sum. Added to this expense is another much larger amount that is lost to wage earners throughout the nation by reason of their loss of wages or income while sick or otherwise disabled.
Accident and health insurance is a form of insurance devised to protect against these economic losses. It protects the earning of wage earners and finishes financial aid to the family of the breadwinner by the payment of his doctor and hospital bills. Today, business and professional men, farmers, industrial workers, clerks and those engaged in various occupations, whose earning power is shut off for a week, a month, or sometimes years, because of accidents or illness can insure themselves against this financial loss by accident and health insurance.
Protection is available to all types of workers and the cost(called the premium)ranges from a few cents a day for small or limited policies to a month for policies paying larger amounts(called indemnities). Policy is another name for an insurance contract(合同). Most accident and health policies are cancelable policies—that is, they are sold for a definite term such as a week, a month, or a year, similar to contracts of fire insurance and automobile liability insurance. There are, however, policies which cannot be canceled or terminated(终止)by the insurance company until the policyholder reaches an age at which he usually has no further earning power—most often at sixty or sixtyfive years. These noncancelable policies cost more than the cancelable policies.What is the passage mainly concerned about?
| A．Everyone will have some sort of illness or accident. |
| B．Accident and health insurance is available to everyone. |
| C．Cancelable insurance policies are better than noncancelable one. |
| D．Insurance is a good protection against accidents and illness. |
Every year in the United States there are________.
| A．more people die in accidents than of illness |
| B．more people who are ill than those injured in accidents |
| C．more outdoor accidents than indoor accidents |
| D．more people injured in accidents than those who are constantly ill |
The heaviest pain and suffering caused by accidents and illness are________.
| A．colds and influenza | B．financial losses |
| C．loss of time | D．invalidism |
Accident and health insurance will protect people by________.
| A．covering their medical expenditure |
| B．paying their wages |
| C．restoring their earning power |
| D．providing policyholders with the money they need to survive |
