A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5 years less than their southern counterparts because they breathed dirtier air.
China itself made the comparison possible: for decades, a now-discontinued government policy provided free coal for heating, but only in the colder north. Researchers found significant differences in both particulate pollution of the air and life expectancy in the two regions.
While previous studies have found that pollution affects human health, "the deeper and ultimately more important question is the impact on life expectancy," said one of the researchers, Michael Greenstone, a professor of environmental economics at Massachusetts Institute of 一Technology. "This study provides a unique setting to answer the life expectancy question because the(heating) policy dramatically changes pollution concentrations（含量），，，Greenstone said in an email. "Further, due to the low rates of migration in China in this period, we can know people's exposure over long time periods," he said.
The policy gave free coal for fuel boilers to heat homes and offices to cities north of the Huai Riv饥which divides China into north and south. It was in effect for much of the 1950-198,0 period of central planning, and, though discontinued after 1980, it has left a legacy（遗留） in the north of heavy coal burning, which releases particulate pollutants into the air that can harm human health. Researchers found no other government policies that treated China's north differently from the south.
The researchers collected data for 90 cities, from 1981 to 2000, on the annual daily average concentration of total suspended（悬浮的）particulates. In China, those are considered to be particulates that are 100 micrometers or less in diameter, sent out from sources including power stations, construction sites and vehicles. Among them, PM2.5 is of especially great health concern because it can go deep into the lungs.
The researchers estimated the impact on life expectancies using death data from 1991-2000． They found that in the north, the concentration of particulates was 184 micrograms per cubic meter一or 55 percent higher than in the south, and life expectancies were 5.5 years lower on average across all age ranges.The main idea of this passage is that＿·
| A．research in China finds air pollution shortened life expectancy |

It is implied in the passage that＿·

| B．air quality was comparatively better in South China |
| C．southerners burned coals for heating in the 1980s |

Chinese cigarette packs will have skulls(骷髅),blackened teeth or diseased lungs printed on them in the latest effort to deal with smoking,but one expert said the images may actually attract younger people to take up the habit.
The images would have to take up at least 30 percent of the pack's surface area under rrules that would come into force from January 2009.It was part of a plan that would also see tobacco advertising banned in China by 2011.Similar images are already printed on packs in countries including Singapore,Thailand and Canada.
Chinese are the world's most enthusiastic smokers,with a growing market of more than 300 million making it a magnet for cigarette companies and a focus of international health concern.China has banned smoking on public transport,but it is still allwed in many public places such as restaurants,and it is not uncommon to see people smoking in hospitals.
The average age people take up smoking in some parts of the country had hallen to as low as just over 10.And the new measures could make the problem worse,according to Zhao Cuiping,a youth expert."In analysis over the past decade(十年) on what young people like,they far prefer skulls and other scary images to cats or dogs,"she said.
Chinese cigarettes are also among the cheapest in the world and a packet can cost as little as eight US. cents.
The country needs to take effective measures to cut down smoking or the habit could end up killing 2.2 million Chinese a year by 2020,the World Health Organization said in May.
56.The new designs will be adopted on cigarette packs ______.

第二节（共5小题；每小题2分，满分10分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
The purpose of a letter of application is to help you to "sell" yourself. 71 It should be simple,human,personal and brief without leaving out any necessary facts.
In writing a letter of application,keep in mind that the things a possible employer is most likely to want to know about are your qualifications(条件),your achievements and your aims. 72 If the first few sentences fail to win the reader's attention,the rest of the letter may not be read at all.Try to focus your opening remarks on the needs or interests of the employer not on your own need or desires.For example,instead of beginning with "I saw your advertisement in today's newspaper,"you might say " 73 "or "I have made a survey in my neighborhood to find out how many housewives use your product and why they like it."
74 Be clear about the kind of job for which you are now aplying.College graduates looking for their first positions often ask "Which can I provide in a letter? Employers want experience - which,naturally,no beginner has." The answer is that everything you have ever done is experience.
It is important to write a good strong closing for your letter.Make a specific request for an interview or give the possible employer something definite to do or expect.At excellent idea is to enclose(内附)a stamped,self - addressed envelope with your letter. 75
| A．I have made a careful study of your advertising during the past six months. |
| B．Don't be late for an interview. |
| C．It should state clearly the job you want,and should tell what your abilities are and what you have done. |
| D．Try to avoid generalities. |
E.The opening paragraph is perhaps the most important part.
F.That makes it easier for a possible employer to get in touch with you.
G.At the end of the letter,you should sign your name nicely.
D
For many year,motorcycle riding was considered a male sport.Women usually rode on the seat behind the men driving the two - wheeled vehicle.Now more and more women are taking the front seat.
More than twenty million people in the United States ride motorcycles.The number of female motorcyclists has increased greatly over the past few years.More than ten percent of motorcycle owners in the United States are women.

Female riders have helped change motorcycle culture.The Motorcycle Industry Council says more than five years ago factories began producing equipment that makes riding more pleasant for women.Some bikes now have smaller,softer seats and controls that are easier to reach. Modern clothes for riding look good and still provide protection.Besides,women are now riding motorcycles that are as powerful as the ones men ride.Lady Sprot Riders believe women have earned their place in the sport of motorcycle riding.When speaking of male motorcyclists,the members of the club say:"They Made the Game…We Came to Play!"
