单选题Until the 20th century cigarette smoking was not a widespread habit. The cigarette industry started in the 1870s with the development of cigarette manufacturing machines. It helped produce great numbers of cigarettes very quickly and reduce the price greatly. And consequently more and more people, both men and women, began to smoke cigarettes. Men as a group, however, smoke more than women. But the highest proportion of smokers is found in the age group of 24-44, regardless of sex difference. Income, education and occupation all play a part in determining a person"s smoking habits. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes per day. The situation is somewhat different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower education groups. These more highly educated women tend to smoke more heavily. Among teenagers the picture is similar. There are fewer teenage smokers from upper-income, well-educated families, and fewer from families living in farm areas. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.

单选题 Suppose you set your mind to work on the problem of how you would use your own eyes if you had three more days to see. If with the oncoming darkness of the third night you knew that the sun would never rise for you again, how would you spend those three precious days? What would you most want to let your gaze rest upon? I, naturally, should want most to see the things which have become dear to me through my years of darkness. You, too, would want to let your eyes rest long on the things that have become dear to you so that you could take the memory of them with you in the night that loomed (降临) before you. I should want to see the people whose kindness and gentleness and companionship have made my life worth living. First I should like to gaze long upon the face of my teacher, Mrs. Anne Sullivan Macy, who came to me when I was a child and opened the outer world to me. I should want not merely the outline of her face, so that I could cherish (珍惜) it in my memo ry, but to study that face and find in it the living evidence of the sympathetic tenderness and patience with which she accomplished the difficult task of my education. I should like to see in her eyes that strength of character which has enabled her to stand firm in the face of difficu lties, and that {{U}}compassion{{/U}} for all humanity which she has revealed to me so often. Oh, the things that I should see if I had the power of sight for just three days!

单选题Directions: {{I}}This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 to 45. {{/I}} Placing a satellite into orbit requires a tremendous amount of energy, which is achieved from multistage rockets burning chemical fuels. The first stage of a multistage rocket consists of rocket engines that provide a huge amount of force. The first stage lifts the entire launch vehicle—with its load of fuel, the rocket body, and the satellite—off the launch pad (发射台) and into the first part of the flight. After its engines use all their fuel, the first stage portion of the rocket separates from the rest of the launch vehicle and falls to the earth. The second stage then ignites, providing the energy necessary to lift the satellite into orbit. It, too, then separates from the satellite and any remaining rocket stages. The rest of the launch depends on the satellite's mission. And a third rocket stage provides the energy to lift the satellite to its final orbital altitude. After the satellite has reached the final altitude, another rocket engine fires and gives the satellite a circular orbit. All rocket-engine burns occur at a precise moment and last for a precise amount of time so that the satellite achieves its proper position in space. In 1990 the United States began launching some satellites from aircraft flying at high altitudes. This method still requires a rocket-powered launch vehicle, but because the vehicle does not have to overcome friction with the thick atmosphere found at low altitudes, much less fuel is needed. However, the size of the rocket is limited by the size and strength of the aircraft, so only smaller satellites can be launched this way.

单选题 Scientists can determine someone's favorite food from their body shape. They have discovered that the arrangement of taste buds(舌部味蕾) on the tongue varies for different body types. The scientist team examined 1 000 British adults and divided them into three physiologically recognized body types--ectomorphs, endomorphs and mesomorphs. They determined that a person's body type indicated where they. were likely to have the most taste buds-on the sweet, bitter or salty areas of their tongue. The study showed that ectomorphs, who make up one in three of the population, usually have a small delicate shape, have a sweet tooth but hate bitter foods. Mesomorphs, who make up 20 percent of the population, usually have a muscular shape and prefer salty or bitter foods but dislike sweet foods. Half the British population are endomorphy with soft, rounded bodies, and they like most foods. The findings showed that for two in three people food preference was a physiological rather than a psychological choice. Body shape expert Simon Bradshaw, who takes charge of this team, said: "It appears that simply by looking at an individual" s body shape we can make sure about their .preferences. " But Catherine Collins, of the British Dietetic Association said:" It is difficult to dictate whether our body shape dictates the food we like, or the food we like dictates body shape. " It stands to reason people who prefer most types of foods will be fatter and people who are the endomorph shape tend to find it more difficult to lose weight.
