10、have more confidence in himselfEngineering students are supposed to be examples of practicality and rationality, but when it comes to my college education I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have ch

11、osen a college with a large engineering department, famous reputation and lots of good labs and research equipment. But that“s not what I did. I chose to study engineering at a small liberal-arts university that doesn“t even offer a major in electrical engineering. Obviously, this was not a practica

12、l choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren“t studying science or engineering. My parents, teachers and

13、other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them. I headed off to college sure I was going to have an advantage over those students who went to big engineering “factories“ where they didn“t care if you have values or were

14、flexible. I was going to be a complete engineer: technical genius and sensitive humanist all in one. Now I“m not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses

15、with liberal-arts courses, I have learned there are reasons why few engineering students try to reconcile engineering with liberal-arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don“t mix as easil

16、y as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult.（分数：25.00）(1).The author chose to study engineering at a small liberal-arts university because he _.（分数：5.00）A.wan

When she and her engineer husband married a few years ago, they built a $100,00

21、0, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla“s eyes burned. Her throat was constantly dry. She suffered from

22、 headaches and could hardly sleep. It was as though she had suddenly developed a strange illness. Experts finally traced the cause of her illness. The level of formaldehyde gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitc

23、hen cabinets and wall-to-wall carpeting. The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation“s drive to save energy. The problem itself isn“t new. “The indoor environment was dirty long before energy conservation came along,“ says Mo

24、schandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.“ The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn“t w

25、orry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom build up to dangerous levels.（分数：25.00）(1).It can be learned from the passage that the Ouchidas“ ho

29、 IndoorsD.Traps in Building ConstructionWe can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as well as “regular“ coffee, and it took several years to gain general acceptance (introduction stage). At one poi

30、nt, though, instant coffee grew rapidly in popularity, and many brands were introduced (stage of rapid growth). After a while, people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline when freeze-dried coffees were introduced (stage of decline).

31、 The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for

32、 new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the military? Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A

33、marketer may re-position the product to appeal to new market sections. Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality impr
