Contestants from around the world met in Pomona, California, this month to test their skills at things like driving a car, walking down stairs, and opening doors. Sounds easy, right? But the competitors weren’t people—they were robots!
The bots were participating in(参加) the final round of the US’s DARPA(Defense Advanced Research Projects Agency) Robotics Challenge. This event, which took place on June 5-6, tested robots on how well they could respond during a disaster and the winning team finally took home a $2 million grand prize.
The DARPA challenge was created after the 2011 Fukushima nuclear disaster in Japan. An earthquake caused a tsunami, which damaged a nuclear power plant. Workers at the plant needed to shut off an important valve(阀门), but it was too dangerous for humans to reach it. The US scientists at DARPA wondered whether the disaster could have been avoided if a robot had been sent to do the job. So they set up the robotics competition.
Turning a valve was just one task a robot might have to perform when entering a disaster zone. In addition to doing this, robots participating in the challenge had to navigate a course containing several other tasks: driving and exiting a vehicle, opening a door, walking over or clearing objects, cutting a hole in a wall, plus climbing a flight of stairs.
Teams had to complete the challenge in one hour, and points were awarded based on how quickly the robots completed a task. They didn’t have to attempt all the tasks. To make things even more realistic, challenge organizers caused short computer-system blackouts(断电) that prevented robots and the human operators controlling them from communicating. That means teams had to program their robots to be partially autonomous(独立的). Robots also couldn’t be attached to anything that could keep them from falling down, which happened a lot.
1.What do we know about this year’s DARPA challenge?
A. It lasted five days.
B. It was held in Japan.
C. Its winner got a cash prize.
D. Its winner will work in Fukushima.
2.What does the underlined part “the job” in Paragraph 3 refer to?
A. To open a door. B. To close a valve.
C. To predict a tsunami. D. To rebuild a nuclear power plant.
3.The robots that participated in the US’s DARPA challenge were required to _____.
A. challenge all the tasks
B. have a good sense of smell
C. complete their tasks in an hour
D. act in the dark in the whole process
4.What is the text mainly about?
A. A nuclear disaster. B. A research program.
C. A robotics competition. D. A scientific organization.

Some people describe American society as a salad bowl while others think of it as a melting pot.
In a bowl of salad，all the ingredients are mixed together. 1.____ Together, however, the ingredients make up a unity. All the ingredients of a salad contribute to the finished product. They may be covered with the same dressing (调味酱），but the green vegetables, tomatoes and cooked corn can all be seen for what they are.
From this point of view, America is very much like a salad bowl where individual ethnic groups mix together, yet maintain their cultural uniqueness. People may work together during the day at similar jobs and in the same companies, but at night they may return to their ethnic groups where their own individual culture directs their way of life.
2.____ Each ethnic group has its own special customs, language, food and traditions to protect and defend. This idea of the salad bowl is referred to as cultural diversity； that is， American society is a collection of various cultures living together in harmony within one country.
3.____Here, society is like one large pot of soup. All cultural aspects are mixed together, sacrificing their original identity and keeping a bit of what they were to become a new reality. The Some people describe American society as a saladlonger the soup is cooked, the better the taste and the more likely it will be for the mixture to dissolve. In this sense, America can surely be seen as a melting pot where people from all over the world come to live and work together forming one nation. There are dozens of shared symbols. 4.____In such a culture, symbols like the flag and the nation’s official song serve to break down the walls which separate ethnic groups.
Whether a salad bowl or a melting pot, America can be best described as a mixture of both. 5.____
A. Both are correct depending on one-s point of view.
B. They never lose their shapes, colors or tastes.
C. This is why there is so much diversity within America.
D, In other words, America is a nation where there is unity in diversity.
E. Thus, one needs to abandon one's culture to be considered "American".
F. They serve to develop the various ethnic groups to create a new American culture.
G. The other theory, which is also used to describe American society, is the melting pot.
