Amsterdam 【小题1】 (call) the “City of Bicycles” because of the convenience of riding bicycles there. In the 1960s, a group of cycling fans had 【小题2】 idea that it would be better for everybody if cars weren't allowed in the city centre and only bicycles were. They were 【小题3】 (hope) that this would help to save energy, reduce 【小题4】 (pollute) and provide free public transport. The group painted hundreds of bicycles white and placed them in lots of neighbourhoods around Amsterdam for people to use.

【小题5】 (fortunate), it didn't work because 【小题6】 (thief) took all the bicycles within weeks! However, more than thirty years later, the “white bike” is back in town — this time with a computer chip to record its every move!【小题7】 (take) a bicycle, you have to insert a special card. People who want to use the bikes 【小题8】 (park) at special parking places have to take them to another special parking place 【小题9】 has enough room. Thanks to the good ideas of lots of people, many people around the world have been enjoying city center streets 【小题10】 cars for many years.

As the saying goes, time is money. And in my opinion, time is even precious than money. Why? Because when money is spent, we still have a chance to earn them back. But when time is wasting, we can never get it back. There is no doubt whether time is very limited, and even a minute is of great value. We should make fully use of time to do what should be done. It’s the pity that a lot of people still didn’t appreciate the value of time. They are wasting their time doing nothing of useful. We should form the good habit of race against time and make a difference in our world.

   Cellphones, tablets, and computers are keeping children and teenagers awake at night-even when they' re not in use, according to new research. A study published on Monday in JAMA Pediatrics says that media devices are causing kids to sleep less and reducing the quality of sleep that they get. This leads to trouble of staying awake the next day.

Researchers analyzed hundreds of studies of children and teens aged 6-19. The scientists found a strong and consistent association between the use of technology at bedtime and poor sleeping. The reason is not just that kids are staying up too late with their devices. Using a computer can overstimulate the mind and emotions, the researchers say. A smartphone or tablet also gives off a light that affects the body's natural timing. These factors contribute to poor quality sleep. And many kids could be at risk. According to the study,72% of all children and 89% of adolescents have at least one device in their sleep environment. Most of these devices are used near bedtime.

"The harmful association between screen-based devices and kids' sleep is a major public health concern," the study concludes. In their conclusion, the researchers urge parents to understand the damaging influence of device use before sleep.
