下列各句中，没有语病的一项是（   ）

    Why do people like what they like? Scientists have taken on the task of solving this mystery(奥秘)for ages. In the 1960s, psychologist Robert Zajonc conducted a series of experiments where he showed people nonsense words and random shapes. Afterward he asked his subjects which they preferred out of ever thing they had been shown. In study after study, people always chose the words and shapes they had seen the most. Their preference was for familiarity.

    This discovery was one of the most important findings in modern psychology. But the preference for familiarity has clear limits. People get tired of even their favorite songs and movies. On one hand, humans seek familiarity, because it makes them feel safe. On the other hand, people love the thrill of something new. This change between familiarity and discovery affects ns all the time- not just our preferences for pictures and songs, but also our preferences for ideas and even people.

    For that reason, the power of familiarity seems to be strongest when a person isn't expecting it. The opposite is also true: A surprise seems to work best when it contains some familiarity. Nobody knows this better than Raymond Loews, who is considered to be the "father of industrial design. He had a theory that he said could help artists sell anything to anyone. He called it MAYA --"Most Advanced Yet Acceptable""To sell something surprising, make it familiar; and to sell something familiar, make it surprising," he said.

    One of Loewy's final tasks was too add an element(要素)of familiarity to a truly new invention: NASA's first space station. Loewy's biggest contribution to the space station was that he insisted NASA install a window with a view of Earth. Today, tens of millions of people have seen this small detail in films about astronauts. It is hard to imagine a more perfect example of MAYA: a window to a new world can also show you home.

阅读下面四篇短文，从每题所给的A、B、C、D四个选项中选出最佳选项。

B

    Think of life as a game in which you are playing with five balls in the air. You name them work, family, health, friends and spirit and you keep all of them in the air. You will soon understand that work is a rubber ball. If you drop it, it will bounce back.　　

    But the other four balls, family, health, friends and spirit, are made of glass. If you drop one of these, it will be broken and never be the same. You must understand that and try to have balance in your life. How ?　　

    Don't look down on your worth by comparing yourself with others. It is because we are different and each of us is special.　　

    Don't let other people set goals for you. Only you know what is best for yourself.　　

    Don't give up when you still have something to give. Nothing is really over until the moment you stop trying.

    Don't be afraid of difficulties. It is by taking chances that we learn how to be brave.

    Don't shut love out of your life by saying it's impossible. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly; the best way to keep love is to give it wings.　　

    Don't run through life so fast that you forget not only where you've been, but also where you are going.　　

    Don't be afraid to learn. Knowledge is weightless. It's a treasure you can always carry easily.　　

    Don't use time or words carelessly. You can't get them back. Yesterday is history, tomorrow is a mystery*, and today is a gift; that's why we call it “the present”. Life is not a competition, but a trip, step by step.
