[单项选择] Google Closes In on DoubleClick Deal
Score one for Google. The Federal Trade Commission ruled Dec. 20 that it would not block Google’s (GOOG) proposed $3.1 billion acquisition of leading online ad-serving and tracking firm DoubleClick. The 4-1 decision in Google’s favor marked a major win for the Web search Goliath, which is battling to expand its considerable share of the $30 billion online advertising market beyond tiny text ads related to Web queries.

The discovery of life beyond Earth would transform not only our science but also our religions, our belief systems and our entire world-view. For in a sense, the search for extraterrestrial life is really a search for ourselves--who we are and what our place is in the grand sweep of the cosmos.
Contrary to popular belief, speculation that we are not alone in the universe is as old as philosophy itself. The essential steps in the reasoning were based on the atomic theory of the ancient Greek philosopher Democritus. Yet philosophy is one thing, filling in the physical details is another. Although astronomers increasingly suspect that biofriendly planets may be abundant in the universe, the chemical steps leading to life remain largely mysterious.
Traditionally, biologists believed that life is a freak--the result of a zillion-to-one accidental concatenation of molecules. It follows that the likelihood of its happening again elsewhere in the cosmos is infinitesimal.
A. justifying popular beliefs.
B. making comparisons.
C. looking back on history.
D. posing sharp contrasts.

Another cultural aspect of nonverbal communication is one that you might not think about: space. Every person understands himself to have a sort of invisible shield surrounding his physical body. When someone comes too close, he feels uncomfortable. When he bumps onto someone, he feels obligated to apologize. But the size of a person’s "comfort zone" depends on his cultural ethnic origin For example, in casual conversation, many Americans stand about four feet apart. In other words, they like to keep each other "at arms length", people in Latin or Arab cultures, in contrast, stand very close to each other, and touch each other often.
