50．A。主旨大意题。作者的意图出现在第一自然段最后一句：“But in fact，the opposite is true：more often than not things that lead to happiness involve some pain” (但事实上，导致你幸福的事情多半伴随着痛苦)，故选项A符合题意。

C(words:401&236)

In a few years, you might be able to speak Chinese, Korean, Japanese, French, and English

- and all at the same time. This sounds incredible, but Alex Waibel, a computer science professor at US's Carnegie Mellon University (CMU) and Germany's University of Karlsruhe, announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.

One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.

Another prototype(雏形机) can send translations of a speech to different listeners depending on what language they speak. “It is like having a simultaneous translator right next to you but without disturbing the person next to you,” Waibel said.

Prefer to read? So-called Translation Glasses transcribe(转录) the translations on a tiny liquid-crystal(液晶) display(LCD) screen.

Then there’s the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted in a person's face, according to researchers.

During a demonstration held last Thursday in CMU's Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed - without speaking aloud - a few words in Mandarin(普通话) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”

This particular gadget(器械),when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, “to switch your mouth to a foreign language”. “The idea behind the university's prototypes is to create ‘good enough’ bridges for cross-cultural exchanges that are becoming more common in the world,” Waibel said.

With spontaneous(自发的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.　

49．D。推理判断题。依据文章第一自然段第1句“The way people hold to the belief that a fun-filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness”(人们坚持充满趣味、毫无痛苦的生活就等于幸福这一信条实际上减少了他们获得真正幸福的可能性)。再依据文章最后一句“…all those who are always having so much fun actually may not be happy at all”(……生活中总是有如此多的fun的人实际上也许一点都不幸福)。可以看出要理解真正的幸福是什么就必须把fun和happiness区分开来。因为两者绝不等同。故选项D正确。C项应该是回答“怎样才能获得真正的幸福”这一问题，且作者并没在文中明确提到获得快乐就必须在任何情况下都忍受痛苦。

48．B。推理判断题。依据文章最后一句“And it liberates us from envy：we now understand that all those who are always having so much fun actually may not be happy at all.”说明：我们现在的这种理解就可免除嫉妒，那么反过来，嫉妒产生于我们的理解不当，即misunderstanding，故选项B正确。

47．C。推理判断题。依据文章第4自然段第1句“带有婴儿的父母要是能睡上一整晚觉或度一个三天的假日，那真是太幸运了。在我认识的人中，不会有人用fun(好玩)来描述他们抚养孩子的感受”，似乎会认为作者的意图是B项(出力不讨好，毫无回报的事)或D项(不可避免的痛苦来源)。实际上，作者真实想法应在第2句中体现：但是决定不生孩子的夫妻永远也体会不到看着孩子成长以及和孙子玩耍的那种乐趣、那种欣喜。这种乐趣、欣喜实际就是一种回报。所以选项C正确。

46．A。细节理解题。本题要求学生判断单身汉拒绝结婚的主要原因。依据文章第3段第1行“Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment”(……害怕作出对义务的承诺，即不愿承担义务)。A项与之等同，故正确。

50．What is the author trying to tell us?

A. Happiness often goes hand in hand with pain．
