Finally,she made her 44: one blanket and something else. She 45 all of the cash,but it was only enough for one blanket. She was unable to make the 46 of the purchases.
A gentleman,47 to make his purchase,watched 48 and signaled to me as I was bagging up the blanket for the woman. He told me he wanted to 49 everything else for her. I asked him if he was sure. He 50 .
I quickly and quietly rang out the rest of the purchases 51 I asked the female customer to wait a moment. The 52 came to over $200. The man provided me with his credit card 53 blinking. He 54 and off he went.
I then told the female customer that all of the things were hers and she was 55 and ready to go. She stared at me with complete 56 on her face. The 57 started. I started crying too.

C
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.
29.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.
30.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.
31.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
32.What is the text mainly about?
A. A nuclear disaster.
B. A research program.
C. A robotics competition.
D. A scientific organization.
