Bike sharing programs have been popular in many cities and communities across China. Some in the cycling community believe these programs have many advantages, encouraging the people who might not use a bicycle to ride bikes. Others think that the programs are filled with potential (潛在的) danger and create more problems than they solve.

Biking is great for the environment because it allows people to travel without burning fuel (燃料). People who use bike sharing programs might use them instead of their own car or taxi to travel around their area. This helps to cut down air pollution and creates a culture of eco-friendly (環(huán)保的) transportation. Biking is known to be excellent exercise for both the body and the mind. Also, it's convenient to use. Public bicycle systems offer a convenient, easy-to-use system for people.

We all know that bicycle helmets protect us from injuries (受傷) and should be worn by all cyclists (騎行者). It seems impossible for everyone who doesn't own a bicycle to wear a helmet. And during heavy traffic hours, bicycles might not be available for use. Furthermore, Bike sharing programs make bicycling easy for everyone, whether or not they are familiar (熟悉的) with cycling. Some people will have experience riding in the city, while for others it may be a first-time experience. These people put themselves and others on the road at risk.

A doctor entered the hospital hurriedly after being called in for an important surgery (外科手術(shù)). He found the boy’s father in the hall waiting worriedly.

On seeing him, the father cried out, “Why did you take all this time to come? Don’t you know that my son is in danger?”

The doctor smiled and said, “I’m sorry. I wasn’t in the hospital and I came as fast as I could after receiving the call, and now I wish you’d calm down so that I can do my work.”

“Calm down! What if your son was in this room right now? Would you calm down?” said the father angrily. The doctor smiled again and replied, “We will do our best and you should also pray (祈禱) for your son’s healthy life.”

The surgery took some hours. And then the doctor went out happily, “Thank goodness! Your son is saved!” And without waiting for the father’s reply, he carried on his way running by saying. “If you have any questions, ask the nurse.”

“Couldn’t he wait some minutes so that I can ask about my sons state (情況)?” shouted the father when seeing the nurse.

The nurse answered, tears coming down her face. “His son died yesterday in a road accident. He was at the burial when we called him for your son’s surgery. And now that he saved your son’s life, he left, running to finish his son’s burial.”

After hearing what the nurse said, the dad was in deep thought with a red face.
