单选题
The sentence “Our planet has shrunk” underlined in Paragraph 1 means that.
A

the earth has become physically smaller

B

the more advanced ways of traveling has made the distance between countries shorter

C

the traditional concept of our planet has become out-of-date

D

modern means of communication has made it much easier for people to communicate with each other from different parts of the world

参考答案和解析
正确答案： B
解析：
语义题。前一句指出“新科技以前所未有的形式将这个世界连接起来”。后一句又接着进行解释说“现在的世界变成了一个‘地球村’，因为电话、传真或卫星的连结，各国之间的联系在数秒之内便可完成”。由此可知划线部分“我们的星球‘缩小’了”指的是“现代通讯方式使得世界各地的人们之间的交流更方便了”。

A Record-Breaking Rover
NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance. Since arriving on the Red Planet in 2004,Opportunity has traveled 25 .01 miles,more than any other wheeled vehicle has on another world.
“This is so remarkable considering Opportunity was intended to drive about 1 kilometer and was never designed for distance,”says John Callas,the Mars Exploration Rover Project Manager.
He works at NASA's Jet Propulsion Laboratory in Pasadena,California.“But what is really importantly is not how many miles the rover has racked up,but how much exploration and discovery we have accomplished over that distance.”
The solar-powered Opportunity and its twin rover,Spirit,landed on Mars 10 years ago on a mission expected to last 3 months. The objective of the rovers was to help scientists learn more about the planet and to search for signs of life,such as the possible presence of water.
Spirit stopped communicating with Earth in March 2010,a few months after it got stuck in a sand pit. But Opportunity has continued to collect and analyze Martian soil and rocks.
During its mission,Opportunity has captured,and sent back to Earth,some 187,000 panoramic and microscopic images of Mars with its cameras. It has also provided scientists with data on the planet's atmosphere,soil,rocks,aid terrain.
The rover doesn't seem to be ready to stop just yet. If Opportunity can continue on,it will reach another major investigation site when its odometer hits 26.2 miles. Opportunity has beer working on Mars since January 2004.
Researchers believe that clay minerals exposed near Marathon Valley could hold clues to Mars's ancient environment. Opportunity's continuing travels will also help researchers as the, plan for an eventual human mission to the Red Planet.

Opportunity is a record breaking rover in the sense of________.
A: how long is has stayed in space
B: how far it has traveled
C: how much investment it has involved
D: how many facilities it has been equipped with

答案：B
解析：
根据第一段“NASA's Mars rover Opportunity has boldly gone where no rover has gone before—at least in terms of distance.”可知，“机遇号”比任何漫游车行驶的距离都长。故选B。


从第二、三段可知，“机遇号”并不是为长途行驶而设计的，它本来预定只能行驶大约一千米。因此“机遇号”在被设计时，约翰并没有准确地知道它的价值。故本题选 B。


由第四段“The objective of the rovers was to help scientists learn more about the planet and to search for signs of life , such as the possible presence of water.”可知，把“机遇号”和 “勇气号”送上火星的目的之一是寻找生命的迹象。故本题选D。


根据文章最后两段可知，如果“机遇号”继续行驶的话，在它行驶到26.2英里的时候，它就会到达另一个重要的研究场地——马拉松谷，因此C项正确。倒数第二段第一句说，“机遇号”不会止步于此，故A项错误。B、D项文中并未提到。


由最后一段可知，“机遇号”接下来的工作能够帮助研究人员实施人类最终登陆火星的计划。故B项“科学家正努力把更多的人类送上火星”是正确答案。

第5题：

And that quest has brought______benefits that improve our lives in countless ways.

A.tangible

第6题：

Most of us，when we reached our teens，started looking forward to the day when we would occupy places of our own，far from the confines of our families. We saw this moving away as a chance to strike out on our own，to grow，to spread out wings and experience freedom. At the same time，we regarded this independence as temporary-the thing to do until we found the perfect mate and married. Over the years，many millions of people have made this passage from one family to another，with just a brief，often nervous interval of independence in between. But recently，more and more people have begun to challenge the concept that living together is better than living alone. Being single is now accepted as an alternative lifestyle-one that is natural，rewarding，and complete. In fact，being single has become almost fashionable.


正确答案：
我们大多数人到了十几岁的时候，就开始向往有一天能有自己的独立空间，从而远离家庭的束缚。我们把离开家看做是独立生活、长大成人、展翅飞翔和体验自由的机会。但与此同时，我们认为这种独立只不过是在我们找到满意的伴侣并结婚之前的暂时的事情。这些年中，几百万人们都是这样从一个家庭到另一个家庭过来的，中间经历了一个短暂、并且常常是不知所措的独立阶段。但是最近，这种与人住在一起比独居更好的观念正开始受到越来越多的人们的挑战。独身现在被人们看做是生活方式的另一种选择-这种生活方式是合乎自然的，有意义的，而且是没有什么缺陷的。实际上，独身已经变得近乎流行起来了。
