Helen has always been interested in helping her community (社区). Her first volunteer experience was for the American Red Cross when she was in high school. When she was a school teacher, she also found time to volunteer.

    After she retired (退休), she started volunteering to help the old. When her father was older, he was not able to see as well as he used to, which made her sad because he had always enjoyed reading. She decided it would be fun to read to elderly people in her community.

    She also helped one woman write her stories. Ann was almost 100 years old, and Helen wrote down information about her life when she visited her. She put the information in a book and got it published (出版), Ann was very excited to share her life story with her children and grandchildren.

    After a strong storm hit some southern cities, Helen volunteered again for the American Red Cross. She prepared food and answered phones in a care centre.

    One day Helen read an article in the newspaper about refugees (难民) who needed to learn English. She met once a week with Sahra, a 38-year-old woman from Somalia. Helen gave Sahra a camera and asked her to take pictures of her daily life. In the end, they wrote a book together and used the photos in the book. This helped Sahra learn many new words about her everyday life.

    Helen says, "The real value of my volunteer work is becoming friends with the people I help. They enrich my life as well as I enrich theirs."

    Think about this question: what would it be like if there was no other way to get around and we could only use our feet? {#blank#}1{#/blank#} Also, we would spend a lot of time on the way before we got somewhere. So we really need to thank all those modes of transportation (交通方式(.

    {#blank#}2{#/blank#} The earliest boats were canoes(独木舟). Later there were sailing boats(帆船), but they could only be used in one direction. {#blank#}3{#/blank#} 

In the 19^th century, some modes of transportation that we know today came out, such as the bike, the train and the subway. {#blank#}4{#/blank#} As it got easier to travel, people wanted to get to places faster. In the early 20^th century, the first plane in the world came out. By the 1970s, many families in the UK had a car.

    {#blank#}5{#/blank#} They all make our traveling easier and faster and help us see this world better.

    I am Paul. I am in the classroom. What's under the teacher's desk?

    It's a black schoolbag. Who lost the schoolbag? Let's look at the things in it. This is a pencil box with a pen, a ruler and two pencils in it. This is a Chinese book. I always have my name on my books. But I can't see a name on it. I get(取)the math(数学)book from the schoolbag and have a look. There is no name on it, either(也). How about the music(音乐)book? Let me see. Here is a photo in this book. This is Sally, but I don't know the other two girls in the photo. Is this Sally's schoolbag? I am not sure. I will call Sally and phone her about the lost schoolbag.

    Although the world develops much faster and better, the resources on the earth get fewer and fewer. In order to protect them, something must be done.

    _______________. Water is the source of life. No water, no life. So it's very important for us to do so.

Not only should we protect drinking water and stop polluting it, but also make full use of it.

    _______________. It is crucial. We can't imagine what the life will be like without it Everyone should do his best to save it. Don't forget to turn off the lights or other electric machines when we finish working.

    _______________. They are useful. Please stop cutting them down and use recycled paper instead.

Make our world a green one to live in.

    _______________. Plenty of them can be recycled like cans, paper, bottles, and so on.

    The volunteers often teach people how to recycle, and gave us tips on how to save energy, and we should work together to protect the resources and improve the environment around us.

    We are a bit afraid when we talk about the A/H1N1 flu(甲型H1N1流感).

    Flu

    The A/H1N1 flu sounds really scary and some people died of it. ⑶It is difficult for us to stop it. But it works like other kinds of flu. We catch it in the same way, and we can protect ourselves from the flu in some similar ways.

    ★Pandemic(大流行病)

    The A/H1N1 flu is a pandemic. ⑷The word "|pandemic" sounds like millions of people might die. But that's not what it means at all!

    The pandemic spreads(传播)over a whole country or the whole world. It doesn't mean a high death rate(比率), but just only large groups of people in the world may get it.

    Mask(口罩)

    A mask just keeps a person from breathing in the virus(病毒)that might be breathed out by someone. Wearing a mask isn't a bad idea, but it doesn't mean that the flu is much more dangerous than other kinds of flu.
