I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren't for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the county. But how realistic is the dream?Cities can be frightening places. The majority of the population lives in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of flats. Children become aggressive and nervous-cooped up at home all day, with nowhere to play; their mothers feel isolated from the rest of the world. Strangely enough,
The girl tried many times to sneak across the border to a neighboring country, （ ）each time.
Many objects in daily use have clearly been influenced by scientists but their form and function, their structures and appearance, were determined by technologists, artisans, designers, inventors and engineers using nonscientific modes of thought.Tillie Olsen's fiction and essays have been widely and rightly acknowledged as major contributions to American literature, and her work has been particularly valued by contemporary feminists.That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted.Doctors are men who prescribe medicines of which they knew little, to cure diseases of which they knew less, in human beings of whom they knew nothing.This was the dilemma of the rotten ruling class whose ideology had been discredited and whose power rested on lies and brute force.Being born female and black were two handicaps Gwendolyn Brooks states that she faced from her birth, in 1917, in Kansas.When he catches a glimpse of a potential antagonist, his instinct is to win him over with charm and humor.We must cheek the conclusion in practice, and should not blindly rely on such as was reached merely by calculation.She was waiting for us, her figure defined by the light from the half-opened door.Americans who would be patriots must try to learn what it is that they have in common, what it is in the public that is worth cherishing and preserving; until they know that, their patriotism will have no more content than a bright, loud afternoon parade.
The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illness may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.A multitude of factors, both inherited and environmental, influence the development of health-related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health-related behavior is usually one of personal choice. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Crape drew a comparison they suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.1.The concept of personal choice concerning health is important because（ ）.2.To "live a completely sedentary life-style"(Line 7, Para. 1) in the passage means （ ）.3.Sound personal health choice is often difficult to make because （ ）.4.To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crape to （ ）.5.According to Fries and Crape sound health choices should be based on（ ）.
