Hi, my name is Mei Shan. I study in a high school now. It seems that my life has changed a lot in the past few years. For example, I used to be short but now I am tall. I used to have long hair, but now I have short hair because I have no time to take care of it. I used to be afraid of the sea because I didn't know how to swim, but now I am a good swimmer in our school. As for eating, I used to have meat and eggs but now I like eating more vegetables.

  When I was young, I didn't use to read any books, but now I often read some storybooks. When I was in primary school, I used to play ping-pong with my friends after school, but now I have to go home right now and do my homework. I didn't like math and I used to be terrified of tests, but now I like all the subjects and never mind any tests. In the past, I used to have time to chat with my friends online, but now I am too busy to do it. How I miss my old days!

    This week, our topic is pollution. What are the answers to all of our pollution problems? We asked two experts to give their views.

    ◇Forest Smith is a member of Green First, an environmental group.

    Our future on the Earth looks very bad. We are dumping waste on our land. We can't breathe the fresh air. The sea is polluted too.

    I visited some relatives recently in a small village. They grow their own food and cycle everywhere. They are not wealthy, but they are happy and healthy.

    We must close the factories producing useless products. That will reduce rubbish and air pollution. We must recycle more, give up all cars, and improve public transport.

    A big problem is overpopulation in big cities. We must give up big cities and factories, and go back to a simple way of life.

    ◇John Green is a scientist at a university.

    Things are not as bad as Forest says. We'll have a bright future. We don't need to give up cars but we need to invent better, cleaner engines.

    This won't stop the problem of traffic jams. So we need better public transport. We should also recycle more.

    But some things are getting better. My sister returned last month after living abroad for five years. She said, “Our old neighbourhood doesn't look the same as before－it is cleaner and greener now.”

    In a word, science has brought many improvements to our life.

    A young man went to visit a wise man who lived deep in the mountain{#blank#}1{#/blank#}

    "Excuse me!{#blank#}2{#/blank#} Is it the day we were born or the day we die？Is it the day we fall in love or the day we are successful？"the young man asked．

    "None．The most important day in our lives is today．The wise man replied calmly．

    "Why？"the young man was very surprised．

    {#blank#}3{#/blank#}

    "So is it because of my visit？"

    "Even if nobody visited me today，today is still very important，because today is the only wealth we have．No matter how important yesterday is，it has gone by；{#blank#}4{#/blank#}

    No matter how ordinary and boring today is，it is in our hands．"

    The young man still wanted to ask something，but the wise man stopped him and said，"When we are talking about the importance of today，we have wasted a lot of it．That is to say，part of‘today'has passed．"

    Having understood this，the young man nodded and then went down the mountain．

    {#blank#}5{#/blank#}Therefore，what we should do now is to forget yesterday and tomorrow and catch hold of today!

A．Is it because there is some unusual event taking place today？

B．Actually today is the only wealth and chance we have．

C．No matter how wonderful tomorrow may be，it hasn't come

D．Could you tell me what is the most important day in our lives？

E．He wanted to ask for the wisdom of life．

    Lucy likes English very much. She studies hard. She reads English every morning. She likes speaking English. She often listens to the radio. She likes watching TV. But she only watches it on Saturday evening.

    She doesn't like dancing. But she likes singing. She sings well. She likes driving a car too. Her parents like her. And all the teachers like her, too.

    Han Hong is mainly known for her strong voice and her famous song Heaven's Road. In fact she is not only a singer but also does a lot for charity. When COVID-19 hit Wuhan, Han felt she should do something. She called up famous people and the public to help Wuhan. "I want to call up my friends in the art circles to donate(捐款) and help people affected by this terrible virus outbreak," the 48-year-old singer said on her Sina Weibo, which has over 15 million followers. Within just a week, a large number of Chinese pop stars and the public went into action. Over 278 million yuan and lots of medical supplies(医疗物资) have been donated through her charity organization, Han Hong Love Charity Foundation, which she founded in 2012. Thousands of fans as well as other common people answered her call to help Wuhan. "When you're going through a situation like this, you would like to offer help. There are so many kind people out there," said a fan, who donated through Han's foundation. "It's good to know that there are trucks with medical supplies going straight to the medical workers." Han turned down interviews. Her friend said she was busy coordinating(协调) work in Wuhan. "Many people don't trust charity organizations to use their donations properly. We must make sure the donation process is open and clear. Also, we update(更新) and share detailed information online, so the public know which place the goods and money come from and go to, even a packet of instant noodles." said Han Hong.
