单选题{{B}}Passage Three{{/B}} When 23-year-old Eric Atienza graduated from college last Year, he didn't have a job. Not wanting to give up his apartment and move back with his parents, he did what many young Americans are doing: he signed up with a temp agency, which places workers on short-term jobs. Temporary workers such as Atienza comprise 20 per cent of the U.S. workforce. In 1985, 417,000 workers were classified as temporary help. In 2005, there are more than 2.5 million, according to Labour Department data. Using temporary workers allows companies to increase or decrease the number of staff as their workloads change. It also allows companies to avoid the costs involved in hiring and firing long-term employees. Many temp agency owners and career specialists say temping is a good way for recent graduates to get experience. "Short-term jobs let graduates try out different companies to find the best fit," said Pegi Wheatley, owner of McCall Staffing, a San Francisco temp agency. But things don't always work out that way. "when I started temping, I had this notion that a temporary job could turn full-time. I worked for a friend of mine, but that didn't happen for me," said Atienza, who quickly became bored with his office work. Atienza stayed with the temp agency because he could earn U.S.＄10 an hour doing office work. Other short-term jobs, such as working as a store clerk in a cafe, pay about U.S.＄7. But there were trade-offs for the higher pay. Because in the U.S., health insurance is provided through employer, most temps are not eligible for workplace health benefits. Atienza ran the risk that an accident or illness would land him in the hospital with no way to pay the bill. Other drawbacks, though less serious, still mean that temping for most graduates is exactly what its name implies- a temporary choice. Instability, gaps between contracts, lack of vacation time and isolation from other employees are often-cited negatives. "Temping gave me the time to figure out what I wanted to do, because I could pay off my bills. But none of that came from the jobs themselves," said Atienza, who quit temping last month in favor of a full-time job.

For thousands of years there have been individuals who have tried to {{U}}(56) {{/U}} others to buy the food they have produced or the goods they have made or the services they can {{U}}(57) {{/U}}. But in the 19th century the mass production of goods {{U}}(58) {{/U}} the Industrial Revolution made person-to-person selling inefficient.

At the same time, mass communication, first newspapers and magazines, then radio and television, made mass selling through {{U}}(60) {{/U}} possible. The objective of any advertisement is to convince people that it is in their best {{U}}(61) {{/U}} to take the action the advertiser is recommending.

单选题{{B}}Passage Four{{/B}} A nocturnal(夜间活动的)moth has become the first animal known to see colours in the dead of night. The moth uses this visual talent to find yellow, nectar-packed flowers in the dark, but the finding suggests that other, species also use colour vision at night. Nocturnal moths were thought to find flowers by looking for bright petals against a darker, leafy background. This difference in brightness explains why a yellow flower stands out from green leaves on a black and white photo. To test this idea, researchers at Lund University in Sweden trained nocturnal elephant hawkmoths(豆天蛾)to pick out yellow or blue artificial flowers from eight other flowers of varying shades of grey. They then made moths perform the trick in conditions as dark as a starry but moonless night. The researchers expected the moths to do badly, but to their surprise the insects picked the correct flower 90 per cent of the time. But the moths could not distinguish between lighter and darker shades of a coloured flower, even though they could still tell both from grey. "This tells us it's not a brightness-related cue,” says Almut Kelber, the sensory biologist leading the Lund team. "They could only have used the spectral(光谱的)composition of the signals—which we call colour." The moths use three separate colour receptors: blue, green and ultraviolet. At night, that leaves so little light per receptor that the insects should be almost blind. But hawkmoths have a host of adaptations to compensate. One is a mirror-like structure at the base of the eye, which reflects the light across the photoreceptors for a second time. The structure of the compound eye also allows each facet to supplement the light that strikes it with light from as many as 600 others. Kelber suspects that many other insects, and some higher animals, also use colour vision at night. She plans to look for the ability in nocturnal frogs and toads that use colour to choose their mate. "Why not? she asks. "At night there are just as many colours as during the day."

单选题I have an infatuation (迷恋) with autumn. The colors of the season, and the smells, have always thrilled me. I have always found joy in this time of year. The last few autumns of my life, however, I recollect in shades o gray rather than cheerful oranges and yellows. When I became a single mother, every aspect of life took on new meaning. Since I was used to carrying out most of the parental duties without much help during my marriage, I truly did not foresee how different parenting would become after the marriage was over. But suddenly I realized I was a statistic. The daily routine was not changed so much; it was the angle at which I had begun to look at life. I believed my ex-husband's lawyer was tracking every grade the children made, and I was under a microscope in this new town where the children and I moved our "broken home. " I feared having to eventually establish my family with each new teacher and each new term as a single-parent family. I just wanted to be us again, without the stigma (特征) of the label that put on us. During those few gray years, I would reassure myself that soon things would be better, and that I would someday be able to feel whole again. There is no mathematical equation of adults proportioned to children to equal a stable, loving family. Every family has its strengths. In fact, studies show that in families who read together, eat together and communicate openly, children are likely to succeed academically, as well as socially and emotionally. I am sure these habits are just as effective when practiced in single-parent families. I realize now that I am not a statistic. We are an active, vital family in this charming community, where we are not marked by any stigma of any statistics of any focus groups. We are given opportunity, all of us. We are surrounded by beauty and immersed in possibility. There is joy to be found here, in what we see around us and in creating our own rendition of how we want to be seen. There is strength and grace in our own willingness to break free from conformity without falling behind the barriers of self-imposed limitations or preconceived notions of where we should fit in this world according to research.
