[简答题]Until recently, scientists knew little about life in the deep sea, nor had they reason to believe that it was being threatened. Now, with the benefit of technology that allows for deeper exploration, researchers have uncovered a remarkable array of species inhabiting the ocean floor at depths of more than 660 feet, or about 200 meters. At the same time, however, technology has also enabled fishermen to reach far deeper than ever before, into areas where bottom trawls can destroy in minutes what has taken nature hundreds and in some cases thousands of years to build. Many of the world’s coral species, for example, are found at depths of more than 200 meters. It is also estimated that roughly half of the world’s highest seamounts—areas that rise from the ocean floor and are particularly rich in marine life—are also found in the deep ocean. These deep sea ecosystems provide shelter, spawning and breeding areas for fish and other creatures, as well as protection from strong current

Scientists had until very recently believed that there were around 100,000 human genes, available to make each and every one of us in our splendid diversity. 41) __________. So that grand panjandrum, the human, may not manage to boast twice as many genes as that microscopic nowhere—worm, with its 18,000 genes, the nematode. Even the fruit fly, considered so negligible that even the most extreme of animal rights activists don’t kick up a fuss about its extensive use in genetic experimentation, has 16,000 genes. 42) __________.

Without understanding in the least what the scientific implications of this discovery might be, anybody with the smallest curiosity about people—and that’s pretty much all of us—can see that it is pretty significant. 43) __________. Human complexity, on this information, can he Best explained in the manner it looks to be best explained before scientific evidence becomes involved at all. In other words, in the nature v

[单项选择] Scientists recently revealed an instinct in women untouched and unaffected by the age of technology. Glancing through glossy art books Lee Salk noticed that four times out of five Mary is depicted holding the infant Jesus against her left breast. The Madonna sparked off (bring into action) a series of experiments and observations to determine on which side women hold their babies and why. First he determined that modern mothers still tend to hold their baby on the left. Of 255 right- handed mothers, 83 % held the baby on the left. And out of 32 left-handed women, 78 % held the baby on the left. As a control, women were watched emerging from supermarkets carrying baby-sized packages; the bundles were held with no side preference. Then, dental patients were given a large rubber ball to hold during treatment. The majority clutched the ball to their left side, even when it interfered with the dentist’’s activities. This suggested that in times of tress objects are held against t
