What do you think is the most common illness? Do you get ill sometimes? We are lucky to live now because there are lots of medicines to make people better．

     The most common illness in the world is the cold．It often begins with a sore throat．Then you sneeze and your nose runs．You usually have a headache，too．Often you cough later．It's not a very bad illness but you can feel quite ill．   

     There isn't a cure(治愈)for a cold but you can take medicines to make you feel better．For instance aspirin(阿司匹林)can stop your headache．It is good to rest and to drink a lot of water，too．A doctor once said to me，“With the proper medicine a cold will last for seven，days．With no medicine it will go on for a whole week!”

     Where does our medicine come from? A long time ago people knew that some plants made them feel better．They ate the leaves，the roots，the I fruit or the seeds of those plants．For instance the juice of lemons makes a sore throat feel better．

     In modern times scientists have looked at these plants and found out which chemicals(化学物质)are in them．Many of our medicines today are made from those chemicals．   

     There are some illnesses which we can't cure yet．And nobody has found a cure for old age．But because of modern medicines most people now live longer than their grandparents．   

    In most parts of the world, many students help their schools make less pollution(污染). They join “environment(环境) clubs ”. (1)In an environment club, people work together to make our environment clean. Here are some things students often do.

    No garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags and the bags can be used again. If the classes make the least garbage, we will report them to the whole school!

No car day. On a no car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jump, bike or run. Use your legs! It's lots of fun!

    Turn off the water! Did you know that some toilets(厕所) can waste(浪费) 20 to 40 m³ of water an hour? In a year, that would fill a small river! In environment clubs, students mend(修理) those broken toilets.

    We love our environment. (2)Everyone should take _______ to make our environment ______. Let's work together.

    TFK Kid Reporter Dahlia Suiter spoke with the writer of Writer to Writer: From Think to Ink.

    You just said that you didn't think you'd become a writer. Why?

    I didn't know what I would be. There were times when I wanted to be a scientist. I loved reading about biology.

    ①{#blank#}1{#/blank#}

    I never thought about writing stories for adults (成年人). It was always for children because when I was a child, books were so important to me.

    ②{#blank#}2{#/blank#}

    Revision(修改) is my favorite part. If I can add (增加) something surprising at the same time, I'm happy about that, too.

    ③{#blank#}3{#/blank#}

    Writing is hard, and if you're not having fun with it, why do it? "Save ( 保存) what you write" is very important because you may need it. You may need that part you cut.

    ④{#blank#}4{#/blank#}

    I hope the book will open up new places to go with writing.

    ⑤{#blank#}5{#/blank#}

    Yes. Writing can be a good way to discover (发现) yourself. You learn about yourself when you write. Writing also slows your thinking down, and you can make discoveries and go places that you don't expect.
