单选题Cancer is considered a modem disease, though it was not unknown in ancient times. (The condition was named by the Greeks from their word for crab, presumably because of its clawing, crablike growth). The incidence of cancer has risen dramatically in recent decades, primarily 1 cigarette smoking, and cancer is probably our most dreaded disease today. As a cause of death in the United States, cancer has climbed from less than 6 percent of all deaths in 1900 to over 20 percent today, 2 recent statistics. It is already the leading killer of women aged thirty to fifty-four. And add a killer of the overall population, it is second only to heart disease, 3 close to 430,000 deaths per year. This figure has risen annually since 1949, and if percent trends continue, cancer may well overtake heart disease as the number one cause of death. Can We Fight Cancer More Effectively Today? Although there is still much to be learned about cancer, our knowledge of the disease has grown steadily in recent years. We have a better understanding of the disease and are finding ways to 4 it. Early recognition of the signs of cancer, prompt diagnosis, and aggressive treatment by the appropriate means have made the word cancer less 5 than it used to be. Even people with forms of cancer that are still difficult to treat know that current techniques may 6 them to outwit the disease until improved treatment becomes available. Many cancer victims have hope where there was once despair. Even more important is the fact that some kinds of cancer are 7 caused by preventable factors—for example, 25 to 30 percent of all cancer deaths are related to cigarette smoking, and most skin cancer is caused by 8 exposure to the sun. Not all forms of cancer have such obvious associations, but where risk factors have been 9 , we can use this knowledge and attempt to reduce the odds of developing those particular forms of disease. You and the people you know can 10 your cancer risk as individuals.

单选题As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home . To begin with, all the factors which are part of intelligence — the child's understanding of language, learning patterns, curiosity — are established well before the child enters school at the age of six. Study after has shown that even after school begins, children's achievements have been far more influenced by parents than by teachers, This is particularly true about leaning that is language-related, The school rather than the home is given credit for variations in achievement in subjects such as science. In view of their power it's sad to see so many parents not making the most of their intelligence. Until recently parents had been by educators who asked them not to educate their children. Many teachers now realize that children cannot be educated only at school and being asked to contribute both before and after the child enters school. Parents have been particularly afraid to teach reading at home. Of course, children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually — and the easiest place to do this is at home. Many four and five-year-olds who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.

单选题{{B}}阅读理解三{{/B}} {{B}}Questions 11 to 15 are based on the following passage.{{/B}} Most of us have seen a dog staring at, sometimes snarling at, and approaching a reflection of itself. For most animals, seeing their own image in a mirror acts as a social stimulus. But does the dog recognize itself, or does the reflection simply signal a potential companion or threat? This question is interest for a number of reasons. Apart from curiosity about the level of animals' understanding, research on self-recognition in animals has several benefits. It provides some insight into the evolutionary significance of this skill of self-recognition and into the level and kinds of cognitive competence that the skill requires. Such research also indicates the kinds of learning experiences that determine the development of self-recognition. In addition, work with animals fosters the use of techniques that are not dependent on verbal responses and that may therefore be suitable for use with preverbal children. The evidence indicates that dogs and almost all other nonhumans do not recognize themselves. In a series of clever experiments, however, Gallup has shown that the chimpanzee does have this capacity. Gallup exposed chimpanzees in a small cage to a full-length mirror for ten consecutive days. It was observed that over this period of time the number of self-directed responses increased. These behaviors included grooming parts of the body while watching the results, guiding fingers in the mirror, and picking at teeth with the aid of the mirror. Describing one chimp, Gallup said, "Marge used the mirror to play with and inspect the bottom of her feet; she also looked at herself upside down in the mirror while suspended by her feet from the top of the cage; she was also observed to stuff celery leaves up her nose using the mirror for purposes of visually guiding the stems into each nostril." Then the researchers devised a further test of self-recognition. The chimps were anesthetized and marks were placed over their eyebrows and behind their ears, areas the chimps could not directly observe. The mirror was temporarily removed from the cage, and baseline data regarding their attempts to touch these areas were recorded. The data clearly suggest that chimps do recognize themselves, or are self-aware, for their attempts to touch the marks increased when they viewed themselves. Citing further evidence for this argument, Gallup noted that chimpanzees with no prior mirror experience did not direct behavior to the marks when they were first exposed to the mirror; that is, the other chimpanzees appeared to have remembered what they looked like and do have responded to the marks because they noticed changes in their appearance.
