单选题More Than a Ride to School The National Education Association claims, "The school bus is a mirror of the community." They further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. They are right—sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl. Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl"s bus driver since kindergarten. Last year when Liesrs family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus. This year Liesl is a senior and will enjoy her last year riding the bus. She says, "It"s been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you"re a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree. Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Company. Larry Althouse, president of the company, acknowledges Bruce Hardy"s outstanding record: "You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record. He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles. Hardy"s reputation is made further evident through the relationships he has made with the students that ride his bus." Althouse further adds, "Althouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come." Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl"s mother Carol also enjoys fond memories of riding Bruce Hardy"s bus to the Octorara School District.

单选题Dining Custom Every land has its own dining custom, and the United States is no exception. Americans feel that the first rule of being a polite guest is to be on time. If a person is invited to dinner at 6.30, the hostess expects him to be there at 6.30 or not more than a few minutes after. Because she usually does her own cooking, she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come. If he is late, the food will not be so good, and the hostess will be disappointed. When the guest cannot come on time, he calls his host or hostess on the telephone, gives the reason, and tells at what time he thinks he can come. As guests continue to arrive, the men in the group stand when a woman enters and remain standing until she has found a chair. A man always rises when he is being introduced to a woman. A woman does not rise when she is being introduced either to a man or a woman unless the woman is much older. When the guests sit down at a dinner table, it is customary for the men to help the ladies by pushing their chairs under them. Even an American may be confused by the number of knives, forks, and spoons besides his plate when he sits down to a formal dinner. The rule is simple, however: use them in the order in which they lie, beginning from the outside, or watch the hostess and do what she does. The small fork on the outside on the left is for salad, which is often served with the soup. The spoon on butter spreader, on a small bread-and-butter plate at the left. As the bread is passed, each guest puts his piece on the bread-and-butter plate.

单选题Smoking Can Increase Depressive Symptoms in Teens While some teenagers may use cigarettes to "self-medicate" (自我治疗) against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually 1 depressive symptoms in some teens. "This observational study is one of the few to examine the perceived 2 benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto. " 3 cigarettes may appear to have self-medicating effects or to improve mood, in the long 4 we found that teens who started to smoke reported higher depressive symptoms." As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to 5 mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools 6 in high, moderate and low socioeconomic neighbourhoods. Participants were divided into three 7 : never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical 8 ; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how often participants felt too fired to do things; had 9 going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt anxious or tense; and worried too much about things. "Smokers who used cigarettes as mood 10 had higher risks of elevated(提升) depressive symptoms 11 teens who had never smoked," says co-researcher Jennifer O"Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are 12 higher risk of developing depressive symptoms." The 13 between depression and smoking exists 14 among teens that use cigarettes to feel better. "It"s 15 to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.

单选题 Exercise Being Good or Bad Can exercise be a bad thing? Sudden death during or soon after strenuous exertion on the squash court or on the army training grounds, is not unheard of. {{U}} {{U}} 1 {{/U}} {{/U}}trained marathon runners are not immune to fatal heart attacks. But no one knows just {{U}} {{U}} 2 {{/U}} {{/U}}common these sudden deaths linked to exercise are. The registration and investigation of such {{U}} {{U}} 3 {{/U}} {{/U}}is very patchy; only a national survey could determine the true {{U}} {{U}} 4 {{/U}} {{/U}}of sudden deaths in sports. But the climate of medical opinion is shifting in {{U}} {{U}} 5 {{/U}} {{/U}}of exercise, for the person recovering from a heart attack as {{U}} {{U}} 6 {{/U}} {{/U}}as the average lazy individual. Training can help the victim of a heart attack by lowering the {{U}} {{U}} 7 {{/U}} {{/U}}of oxygen the heart needs at any given level of work {{U}} {{U}} 8 {{/U}} {{/U}}the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people, {{U}} {{U}} 9 {{/U}} {{/U}}particular, be screened for signs of heart disease before {{U}} {{U}} 10 {{/U}} {{/U}}vigorous exercise? Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people {{U}} {{U}} 11 {{/U}} {{/U}}undiagnosed coronary heart disease. In North America {{U}} {{U}} 12 {{/U}} {{/U}}over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing is unnecessary. Not many people die from exercise, {{U}} {{U}} 13 {{/U}} {{/U}}, and ECGs (心电图) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people {{U}} {{U}} 14 {{/U}} {{/U}}at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs {{U}} {{U}} 15 {{/U}} {{/U}}, they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.
