If you ears are working well, you hear sounds all the time. You can't switch（关掉）your ears off, even when you are asleep.
Listening
    When you really want to listen to something, you tell brain to focus on that sound. If your ears are healthy and are both working well, they can turn down other sounds while you focus on what you want to hear. If one ear isn’t working ______ the other, they can’t do this as well. If you hearing cells（细胞）have been damaged by too much loud noise or music, what you want to hear can get mixed up and lost in the other sounds around. With healthy ears you can choose what you want to listen to, but you can’t choose what you hear.
Understanding
    Your brain deals with the received sounds and tells you what they mean. Some people have problems understanding what they are hearing because their ears don’t work well and they don’t hear all the sounds. They brain does not get enough information to understand the messages or they may be mixed up.
Selective（选择的）hearing
    Lots of mums and dads think that kids have this “problem”. They think that you select what you are going to hear and what you can’t hear! Many mums say that dads do this, too. In fact, this is something we may all do to try and make our lives a bit easier. Some children wrote what they liked to hear and what they didn’t like to hear.

    On April 2nd，2016，an east China highway pile﹣up has killed three people and injured 31 others．That day was the first day of a three﹣day national holiday marking the Tomb﹣Sweeping Day（清明节）．
    Two people died in a local hospital where nine others are being treated．Another person died after treatment failed in a larger hospital in Wuxi where 22 remain hospitallized，Changzhou traffic police updated on its official microblog account at Weibo．com．
The accident happened at the Changzhou section of the highway linking Shanghai and Nanjing．It drew public attention as people began posting photos and videos on Chinese social media WeChat and Weibo．Images showed dozens of trucks，buses and cars crashed into each other．People were standing on the top of the vehicles（运载工具）．
    Local police told Xinhua Press that at least two trucks，three buses and 20 cars were involved．Rainy and foggy weather caused poor visibility and slippery mads．
What's more，it was difficult for ambulances（救护车）to get to the scene of the accident because the life emergency lane（生命通道）was filled with vehicles so that the doctors couldn't get there to save the injured．
    The Ministry（部长）of Public Security told traffic departments nationwide to keep a look out for vehicles using the emergency lane occupancy．
All highways in China leave the right lane as the emergency lane．Some drivers，however，pay no attention to this rule．Therefore，the police call on drivers to follow the rule strictly and offer the injured more hope of being saved．
    The ministry also asked the police to watch the traffic more carefully so as to quickly discover the potential（潜在的）danger．The police have decided to add electronic monitoring instruments to catch the violations and heavily fine drivers for it．

Dear Jeff,

Li Hua

    One morning, a blind boy sat on the steps of a building with a hat by his feet. He held a sign which said “I am blind, please help me.” There were only a few coins in the hat. A man was walking by. He took out a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words on it. He put the sign back so that everyone who walked by could see the new words.
    Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized (辨认出) his footsteps and asked, “Are you the one who changed my sign in the morning? What did you write?” The man said, “I only wrote the truth. I said what you said, but in a different way.” What he had written was, “Today is a beautiful day, but I cannot see it.”
    Do you think the first sign and the second sign were saying the same thing?
    Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but he could not enjoy it because he was blind. The first sign simply said the boy was blind, while the second sign told peop le they were so lucky that they we re not blind.
    There are at least two lessons we can learn from this simple story. The first is: Treasure (珍惜) what you have. Someone else has less. Try your best to help those who need your help. The second is: Be creative. Think differently. There is always a better way.
