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) __________.

[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.

[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

[简答题]If one believed that the universe had a beginning, the obvious question was: What happened before the beginning What was God doing before He made the world Was He preparing Hell for people who asked such questions The problem of whether or not the universe had a beginning was a great concern to the German philosopher, Immanuel Kant. He felt there were logical contradictions, or Antinomies, either way. If the universe had a beginning, why did it wait an infinite time before it began He called that file thesis. On the other hand, if the universe had existed forever, why did it take an infinite time to reach the present stage He called that the antithesis. Both the thesis, and the antithesis, depended on Kant’s assumption, along with almost everyone else, that time was Absolute. That is to say, it went from the infinite past, to the infinite future, independently of any universe that might or might not exist in this background.
