单选题Reading involves looking at graphic symbols and formulating mentally the sounds and ideas they represent. Concepts of reading have changed (51) over the centuries. During the 1950's and 1960's especially, increased attention has been devoted to defining and describing the reading process. (52) specialists agree that reading (53) a complex organization of higher mental (54) , they disagree (55) the exact nature of the process. Some expels, who regard language primarily as a code using symbols to represent sounds, view reading as simply the decoding of symbols into the sounds they stand (56) . These authorities (57) that meaning, being concerned with thinking, must be taught independently of the decoding process. Others maintain that reading is (58) related to thinking, and that a child who pronounces sounds without (59) their meaning is not truly reading. The reader, according to some, is not just a person with a theoretical ability to read but one who (60) reads.

单选题Up in Smoke I began to smoke when I was in high school. In fact, I remember the evening I was at a girlfriend"s house, and we were watching a movie—a terribly romantic movie. He (the hero of the movie) was in love, she (his lady) was beautiful, and they were both smoking. My friend had only two cigarettes from a pack in her mother"s purse, and she gave one to me. It was my first time. My parents didn"t care much. They both smoked, and my older brother did too. My mother told me that smokers don"t grow tall, but I was already 5"6" (taller than most of the boys in my class), so I was happy to hear that " fact ." In school, the teachers talked against smoking, but the cigarette advertisements were so exciting. The men in the ads were so good-looking and so successful, and the women were—well, they were beautiful and sophisticated (老于世故的). I read a book called How to Stop Smoking. The writer said that smoking wastes time, and that cigarettes cost a lot of money. "So what?" I thought. The book didn"t say that smoking can take away years of your life. But ten years later, everyone began to hear about the negative effects of cigarette smoke: lung disease, cancer, and heart problems. After that, there was a health warning on every pack of cigarettes. I didn"t pay much attention to the reports and warnings. I felt healthy, and I thought I was taking good care of myself. Then two events changed my mind. First, I started to cough. I thought it was just a cold, but it didn"t get better. Second, my brother got lung cancer. He got sicker and sicker. My brother and I used to smoke cigarettes together over twenty years ago, and we smoked our last cigarettes together the day before he died. I sat with him in his hospital room, and I decided to quit. "No more cigarettes, ever," I said to myself. However, it was very hard to stop. Nicotine (尼古丁) is a drug; as a result, cigarettes cause a powerful addiction. I tried several times to quit on my own—without success. I made excuses. I told myself: Smoking helps me keep my figure—i.e. I don"t gain weight when I smoke. Smoking not only relaxes me but it also helps me think clearly, I"m a free, liberated woman. I can smoke when I want to. Finally, I ran out of excuses—I might say my excuses went up in smoke. I joined the "Stop Smoking" program at the local hospital, which also ended up in failure.

单选题IS the Tie a Necessity? Ties, or neckties, have been a symbol of politeness and elegance in Britain for centuries. But the casual Prime Minister Tony Blair has problems with them. Reports suggest that even the civil servants may stop wearing ties. So, are the famously formal British really going to abandon the neckties? Maybe. Last week, the UK"s Cabinet Secretary Andrew Turnbull openly welcomed a tieless era. He hinted that civil servants would soon be free of the costliest 12 inches of fabric that most men ever buy in their lives. In fact, Blair showed this attitude when he had his first guests to a cocktail party. Many of them were celebrities without ties, which would have been unimaginable even in the recent past. For some more conservative British, the tie is a must for proper appearance. Earlier, Labor leader Jim Callaghan said he would have died rather than have his children seen in public without a tie. For people like Callaghan, the tie was a sign of being complete, of showing respect. Men were supposed to wear a tie when going to church, to work in the office, to a party—almost every social occasion. But today, people have begun to accept a casual style even for formal occasions. The origin of the tie is tricky. It started as something called simply a "band". The term could mean anything around a man"s neck. It appeared in finer ways in the 1630s. Frenchmen showed a love of this particular fashion statement. Their neckwear impressed Charles Ⅱ, the king of England who was exiled to France at that time. When he returned to England in 1660, he brought this new fashion item along with him. It wasn"t, however, until the late 18th century that fancy young men introduced a more colorful, flowing piece of cloth that eventually became known as the tie. Then, clubs military institutions and schools began to use colored and patterned ties to indicate the wearer"s membership in the late 19th century. After that, the tie became a necessary item of clothing for British gentlemen. But now, even gentlemen are getting tired of ties. Anyway, the day feels a bit easier when you wake up without having to decide which tie suits you and your mood.

单选题Caffeine Caffeine is probably the most widely used drug in the world. Humans have been consuming caffeine for hundreds of years, primarily in the form of coffee, tea, and cocoa. Habitual coffee and tea drinkers had long been observed to have a lower incidence of non- melanoma (黑色素瘤) skin cancers, although no one knew why. A recent study found that caffeine affects skin cells damaged by ultraviolet radiation, a main cause of skin cancer. Caffeine interferes with a protein that cancerous cells need to survive, leaving the damaged cells to die before they become cancerous. Drinking caffeinated coffee has also been associated with a decreased incidence of endometrial (子宫内膜的) cancer—that is, cancer of the cells lining the uterus—the strongest effect appears to be in overweight women, who are at greatest risk for the disease. Researchers believe blood sugar, fat cells, and estrogen (雌性激素) may play a role. Although the mechanism remains unknown, people who drink more than two cups of coffee or tea a day reportedly have about half the risk of developing chronic liver disease as those who drink less than one cup of coffee daily; caffeinated coffee has also been associated with lowered risk of cirrhosis (肝硬化) and liver cancer. While many of caffeine"s undesirable effects, such as elevated heart rate and blood pressure, are brief, some short-term benefits, including pain relief, increased alertness, and increased physical endurance, have also been attributed to caffeine. As a component of numerous over the counter diet pills and pain relievers, caffeine increases their effectiveness and helps the body absorb them more quickly. By constricting (收缩) blood vessels in the brain, it can alleviate headaches—even migraines (偏头痛)—and can help counter the drowsiness (眩晕) caused by antihistamines (抗组胺药). Caffeine does not alter the need for sleep, but it does offer a temporary solution to fatigue for people who need to stay alert. Research has shown that sleep deprived individuals who consumed caffeine had improved memory and reasoning abilities, at least in the short term. Studies of runners and cyclists have shown that caffeine can improve their stamina—hence its addition to energy boosting sports drinks. People who consume a lot of caffeine regularly may develop temporary withdrawal symptoms, headache being the most common, if they quit or cut back on it abruptly. Fortunately, these symptoms last only a day or two in most cases. Individuals who are more sensitive to the stimulatory side effects of caffeine may want to avoid it, but most doctors agree that the equivalent of three cups of coffee a day does not harm healthy people. There is no medical basis to give up daily caffeine and many reasons to include a moderate amount in one"s diet.
