It was very cold outside my car. I did not want to get out of it1we passed by a cafe. Suddenly I noticed a short old man,2 with some bits of cloth, shaking(摆动)with the cold. He was waiting for anyone who would3 him a coin or a cup of hot coffee.
I asked my4 to go over and hand this old man something. He5 into my husband’s face, smiled and said, “6 . ” I felt so happy and I wished the old man could live7 the cold night.
I was sure to meet him again and find out how he was the next8, as I have to pass this way every day. I did so the next evening, and he remembered the9and came up to my window and10 at me. This time I offered(提供) him a11of food. He reached out for the bag and I gave him my hand. He12 the food, smiled and said, “May God bless you.” I looked at the old man and he13 me think of my father.
I do hope all of us will remember that maybe one day, it could happen to one of us,14 please do not pass by a15 person without offering at least a word of love and a kind smile or an act of kindness of any kind.

Imagine this：A television screen has the size and thickness of a piece of paper．You carry it around in your pocket and take it out when you want to watch a show．Imagine a guitar so tiny that you can’t see it with the human eye，but you can hear sound when its strings（弦）are pulled．

Nanotechnology is the science that deals with doing things in a very small way, and it is being studied and developed all over the world．Many scientists say nanotechnology will produce the next industrial revolution（工业革命）．

Perhaps nanotechnology will have the biggest influence on medical science．Imagine nanobots（纳米机器人）in medicine．Thousands or even millions of tiny machines can he sent into the human body with different tasks．For example，they can be designed（设计）to find and kill cancer cells or viruses（病毒）．Other machines may stay in the human body for ever to help organs（器官）that are not working properly．

When could all of these happen? Scientists believe that most of these are possible in the next 30 years. Thousands of scientists around the world are working on these micro-machines．Nanotechnology is just around the corner．
