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 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 bff 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 bots 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.

President Barack Obama renamed North America，s tallest mountain this week. For almost 100 years,the 20,310-foot Alaskan peak has been identified on most maps as Mount McKinley. Its name is now officially Denali.
This “new” official name isn't really new at all. Obama changed the mountain's name to Denali because,for generations,that's what people in Alaska have called it. The Athabascan people,a Native Alaskan group,named the peak Denali long ago. It means “high one” or “great one."
“We are officially renaming the mountain Denali in recognition of the traditions of Alaska Natives and the strong support of the people of Alaska,” said U.S. Interior Secretary Sally Jewell. Alaska Senator Lisa Murkowski praised Obama's move. “I'd like to thank the president for working with us to achieve this significant change to show honor,respect,and gratitude to the Athabascan people of Alaska,she said.
The name Mount McKinley got its start in 1896. At that time,there was a gold rush going on in Alaska. A gold prospector(勘探者) wanted to honor William McKinley of Ohio,who had just been nominated(提名) to run for U.S. president.McKinley would go on to become the nation's 25 th president. He was killed in 1901,six months into his second term as president. The U.S. Congress made the name Mount McKinley official in 1917.
Native Alaskans were insulted(侮辱) by the name change. The result has been a political tug-of-war between Alaska and Ohio. Since 1975,Alaska politicians have pushed Congress to change the name back to Denali. Now that President Obama has changed the name,some people in Ohio are very unhappy. “This political change is insulting to all Ohioans” said Congressman Bob Gibbs,who is from that state.
Denali also made news this week for another reason: U.S. officials decreased its official height by 10 feet. The United States Geological Survey announced that Denali is 20 ,310 feet high,not 20,320 as previously thought. The mountain has not shrunk (萎缩) . Advances in technology allowed scientists to take more accurate measurements of it.
29. Why has the U.S. government renamed its tallest mountain?
A. To end a long political debate.
B. To show respect for Alaska Natives.
C. To remember the nation's 25 th president.
D. To officially identify the mountain's name on maps.
30. What's Ohioans’ attitude towards the new name of Mount McKinley?
A. Excited. B. Amazed.
C. Puzzled. D. Disappointed.
31. What do we know about Mount Denali?
A. It is actually 20 ,310 feet in height.
B. It was found by a gold prospector.
C. It was originally named McKinley.
A. It isn’t North America's tallest mountain.
32. What would be the best title for the text?
A. A political tug-of-war
B. From McKinley to Dendi
C. The tallest mountain found
D. In honor of William McKinley
