One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill. Grow
6、ing to two or three inches long, krill provide the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Realizing that this whale may grow 100 feet and weigh 150 tons at maturity, it is not surprising that each one devours more than one ton of krill daily. Krill swim ab
7、out just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic. Because of their pink color, they often appear as a solid reddish mass when viewed from a ship or from the air. Krill are very high in food value. A pound of these crustaceans contains about 460 caloriesab
8、out the same as shrimp or lobster, to which they are related. If the krill can feed such huge creatures as whales, many scientists reason, they must certainly be contenders as new food source for humans. 1.Which of the following best portrays the organization of the passage?

14、he entire growth, however, was in manufacturing, and especially in no – blue-collar jobs This trend is the same in all developed countries, and is, indeed, even more pronounced in Japan. It is therefore highly probable that in 25 years developed countries such as the United States and Japan wi
15、ll employ no larger a proportion of the labor force I n manufacturing than developed countries now employ in farming – at most, 10 percent. Today the United States employs around 18 million people in blue-collar jobs in manufacturing industries. By 2010, the number is likely to be no more than 12 million. In some major industries the drop will be even sharper. It is quite unrealistic, for instance, to expect that
