填空题Contrary to common belief social media websites such as Facebook do not 1 personal ties, they strengthen them in unique ways for different age groups, according to a new study. The rapid spread of Facebook, which has more than 500 million users worldwide, has prompted concerns about its 2 effects, but researchers at the University of Texas have 3 a different conclusion. "Our findings suggest that Facebook is not supplanting face-to-face 4 between friends, family and colleagues," said S.

More than 60 percent of Facebook users said posting status updates was among the most popular activities, followed by 60 percent who wrote comments on their profile and 49 percent who 7 messages and comments to friends. The researchers also found that although about the same number of men and women use Facebook, they do so in different ways. "There is a 8 difference in orientation in how to use a tool like Facebook. We found that for women the content tends to be more 9 , and (they) are especially interested in using it for connection," said Watkins. "For men, it"s more functional," he added.

填空题It's a good idea to apply sunscreen before heading to the beach if you don't want to burn. But for marine animals like whales, they don't have that (1) . Species like sperm whales can spend up to six hours at the ocean's surface in between dives, (2) in the sunlight. So how do they protect themselves from a serious case of sunburn? It turns out that their bodies have a similar defense (3) against the sun's UV radiation as people. Blue whales—which have the lightest skin color of the three species—tan during their summer stay before (4) back to their northern feeding grounds. Sperm whales don't tan. They can receive an "overdose" of UV radiation during their hours at the ocean's surface, and they have proteins that (5) protect their cells from UV damage. This process is (6) to how human bodies produce antioxidants in response to molecules that can cause a lot of genetic and cellular damage. And fin whales escape sun damage thanks to their high levels of melanin—a dark substance in the skin to protect humans from UV radiation. Older whales and whales with less (7) of melanin in their skin—like blue whales—had the greatest level of damage in their mtDNA. Fin whales, which had the greatest amount of melanin, had the least amount of mtDNA damage. Now that the ozone layer that shields Earth from UV radiation is gradually (8) , it's important to know what the consequences are for whales and dolphins, especially for (9) or endangered species. Although it's difficult to tell what causes many of these skin conditions, UV damage is one cause. Even though whales have (10) defenses to UV radiation, high exposure can still be harmful.

填空题Diamonds have little intrinsic value and their price ______(几乎全凭它们的稀有).

填空题Personality is to a large extent inherent — A type parents usually bring about A type (42) But the environment must also have a (43) effect, since if competition is important to the parents, it is likely to become a major factor in the lives of their, children. One place where children (44) up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools (45) the 'win at all costs' moral standard and (46) their success by sporting achievements. The current (47) for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B type fellows. Being too keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, (48) dead seconds after saying: 'Rejoice, we conquer! ' By far the worst form of competition in schools is the (49) emphasis on examinations. It is a rare school that allows pupils to concentrate on those things they do well (50) . Obviously, it is neither practical nor desirable that all A youngsters change into B's. (51) It is top management. If the preoccupation of schools with academic work was lessened, more time might be spent teaching children surer values. (52) It is surely a mistake to choose our doctors exclusively from A type stock. B's are important and should be encouraged.
