On a cold winter evening, I was walking home alone, when suddenly came screams (呼喊声) from behind some tress.1 I slowed down to listen, and 2 that what I was hearing were the sounds of a fight. A woman was being attack (袭击) not far from where I 3.
“Should I go to help her?” I thought. I was worried about my own 4 , and I regretted having suddenly decided to take a new way home that night. “What if I am 5 too? Shouldn't I just6 to the nearest phone and call the police?” But already the girl's 7 were growing weaker. I knew it was time for me to act fast because I could not 8 the life of this unknown woman, 9 it meant risking my own life.
I am not a 10 man. I didn't know where I found the 11 and physical strength (体力), but once I had finally 12 to help the girl, I changed suddenly. I ran behind the bushes and 13 the attacker off the woman. Struggling, we fell to the ground, where we fought for a few minutes 14 the man jumped up and ran away.
15 heavily, I came up to the girl, who was crying. In the 16 I could not see her clearly, but I could certainly 17 her shock. Not wanting to frighten her any further, I spoke to her from a distance.
“It's OK,” I said 18“The man ran away. You're safe now.” There was a long stop and then I heard the words, said in both wonder and 19 “Dad, is that you?” And then, from behind the tree, stepped my youngest 20 Katherine.
Last year, I was assigned to work at an office near my mother's house.1 ， I stayed with her for a month. During that time, I helped her out with the housework and contributed to the 2.
After less than a week, I started to3 the groceries were running out pretty quickly.4 ， I began observing my mother's daily routine for two weeks. To my 5 ， I found that she would pack a paper bag full of canned goods and 6every morning at about nine. She took the food to the slums (贫民窟) and distributed it to street 7.
I asked around and 8 my mom was popular in the area. The kids looked up to her as if she were their own mother. Then it hit me—why didn't she want to tell me about what she'd been doing? Was she 9 that I would stop buying the groceries if I knew the truth?
When she got home, I told her about my discovery and 10she could react, I gave her a big hug and told her she didn't need to keep it a 11 from me. She told me that 12of the children lived with an old lady in a shelter while others 13 on the streets. For years, my mom has been helping out by 14them whatever food she could 15. I was so moved by how 16 she was. She used what was 17 for her to help others in need. And I was so18 of her.
I 19 to buy groceries for my mom. But now, I always add a(n)20 bag for her other children.

Earthquake rescue robots have experienced their final tests in Beijing. Their designers say with these robots, rescuers will be able to buy more time to save lives during an earthquake.
This robot, looking like a helicopter, is called the detector (探测器) bot. At about 4 metres long, it took about 4 years to develop the model. Its main functions are to collect information from the air, and deliver goods of up to 30 kilos to people trapped by an earthquake.
This robot is equipped with a high 360degree panoramic (全景的) camera. It can work day and night and also be able to send the latest pictures from the quake area.
Dr Qi Juntong, from Chinese Academy of Sciences, said, "The most important feature of this robot is that it doesn't need distant control. We just set the information on it, and then it takes off, and lands by itself. It flies as high as 3,000 metres, and as fast as 100 kilometres per hour."
This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers can't go.
The robot is equipped with a camera that can work in the dark, as well as a detector that not only finds people, but can also detect poisonous gas.
Another use for the rescuers is the supply bot, with its 10metrelong pipe. People trapped in the ruins will be able to get supplies including oxygen and liquids.
Experts have said that the robots will be produced, and serve as part of the national earthquake rescue team as soon as next year.
