Shanghai is one of the first cities in China to see bike sharing fever. Shared bikes can now be found all over the city.     36    On streets see riders of your age. Some might even be younger than you. Unluckily, there have been some accidents involving (涉及) shared bikes.    37    

One of the most serious accidents took place in March. One Sunday afternoon, a boy was riding an ofo bike (共享单车). He was hit by a bus and later died. The boy’s parents were not by his side.     38    He was only about 10 years old.

The good news is that Shanghai has been trying to manage bike sharing by making rules. The rules are still being discussed, but some of the rules have been decided on.     39    Users must be between 1. 45 and 1.95 meters tall.

However, it could be hard to make these rules work. Ou Jing is ofo’s manager in Shanghai. He said the company had banned (禁止) children under 12 from using its service. Yet, young children can still be seen riding ofo bikes. That’s because many ofo bikes use manual (手动的) locks.     40    Ofo has developed electronic locks. However, it will take some time for the company to fix the new locks on all of its bikes.

Most of you are old enough to ride a shared bike. Still, please ride slowly for your own safety. When you finish using the bike, don’t forget to park and lock it properly—for everybody’s safety.

(2018·山东临沂)Campbell Remess is a teenager from Australia. He has been sewing (缝制) teddy bears for sick children for several years.

The story    49     (begin) in 2013 when Campbell was nine years old. He told his parents that he wanted to give Christmas gifts to children in hospitals. But his parents said no, because with nine children of their own, buying presents for sick children would just cost too much. The little boy didn’t give up, however. He decided    50    (make) their presents by himself.

Campbell made his first teddy bear with his mother’s sewing machine in his bedroom. It was hard for him as he had never done this before. He downloaded (下载) patterns from the Internet and learned how to make a teddy bear by    51    (watch) videos online. It took him five hours to finish his first teddy bear. He can now make a teddy bear in an hour. He has also started a project called “Project 365 by Campbell” in which he    52    (try) to make a teddy bear every day.

Young Campbell uses his pocket money to buy materials for making teddy bears. To make more pocket money, he helps his parents with housework whenever he is free. Sometimes, he also sells his teddy bears online    53    (raise) money for sick children. Many people     54     (encourage) by Campbell’s story and they give away free materials to him.

Campbell    55     (give) away about 1,300 teddy bears so far. He is now busy making this year’s teddy bears. He said that he had never thought of stopping and he would keep putting smiles on people’s faces.

(2018·山东临沂)Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That’s because China has the longest mobile phone numbers in the world. Why is that?

The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider (提供者) you are using For example, 135 is for China Mobile Communications Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).

The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That’s enough for each person to have seven or eight phone numbers to use in China.

And mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven’t contacted (联系) for a long time, you may find that its owner has changed.

Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada’s mobile phone numbers are perhaps the shortest in the world: they use seven digits.
