Electric bicycles which run on battery-operated (电瓶) motors are winning over riders of ordinary bikes 41 their speed, quality and environmental advantage.
They were first 42 on 1980s in China, but the selling was not very good. Today, thanks 43 improvements on battery quality, the electric bikes sell well. There are now more than 100 electric bicycle producers in China and 26 million such bicycles were produced in 2011. Japan is another large 44 of such bicycles in the world with a total production reaching 381,721in 2010.
45 China is one of the largest producers of electric bicycles in the world, the 46 of its producers with mass production (大批量生产) is actually small.
Electric bicycles are still 47 in China. Time is needed for people to become familiar with them and accept them. Each bike’s price of between 2,000 yuan (US $318) and 3,000 yuan (US $477) is still 48 for ordinary citizens (民众). Although such bikes are quick, safe and 49 to operate, their batteries still have shortcomings (不足). They weigh more than 10 kilograms; their service life is 50 two years and they 51 400 yuan each.
There were more than 450 million bikes in China in 2006. If just one percent of all these bikes are replaced by electric 52 , the market will be very large. And 53 the battery is further improved and the price is 54 , many of us will not be able to keep back from 55 the latest electric bikes

I was tired and hungry after a long day of work. When I walked into the living-room, my 12-year-old son looked up at me and said, “I 31 you.” I did not know 32 to say, and I just stood there, looking 33at him. My first thought was that he must need help with his homework. Then I asked, “What was that all about ?” “Nothing,” he said, “My teacher said we should tell our parents we love them and see what they say.”
The next day I called his teacher to 34 more about what my son said and how the other parents had reacted﹡. “Most of the fathers had the 35 response﹡ as you did,” the teacher said, ”When I first suggested ﹡that we try this, I asked the children what they thought their parents would say. Some of them thought their parents would be surprised.”
Then the teacher explained , “ I want my students to know that feeling love is an important part of 36 . I’m trying to tell them it’s too bad that we don’t express﹡ our feelings. A boy 37 tell his parents he loves them.” The teacher understands that sometimes it is 38 for some of us to say something .
That evening when my son came to me, I took him in my arms and held on for a while, saying, “Hey, I love you, 39 .” I don’t know if saying that made either of us healthier, 40 I did feel pretty good.
