Our environment is getting{#blank#}1{#/blank#} than before. Now more and more people realize that we should do something to help the Earth. Here are the things we can do to help the Earth: We can recycle glass, metal and paper. We shouldn't throw{#blank#}2{#/blank#} in the garbage can（垃圾箱）! We can{#blank#}3{#/blank#} instead of driving cars! We should try to{#blank#}4{#/blank#}  short showers and turn off all the{#blank#}5{#/blank#} and the TV when we leave the room. All of these things will help the Earth.

    Next time you're in a public place, take a look around you. And {#blank#}1{#/blank#} how many people are using their phones. I can tell you now that it is probably more than half, whether you're on a bus, in a car 6 {#blank#}2{#/blank#}  simply walking down the street.

    I'm not saying that I am not an example of this, but it. {#blank#}3{#/blank#} mazes (使惊愕) me how people can spend so much time on their phones without {#blank#}4{#/blank#} to others. Has it gone too far?

     Recently, my smart phone broke and had to be  {#blank#}5{#/blank#} off for repair for a week or so. I had to use a really old, basic phone just to keep me in touch with my family and {#blank#}6{#/blank#}. All I could do on this phone was to send text messages, make calls and play one game. And I loved it. I loved being {#blank#}7{#/blank#} from the Internet, and I really didn't mind not having updates (更新) about what my friends were doing. It allowed {#blank#}8{#/blank#} to spend more time enjoying my time in London and watching the people {#blank#}9{#/blank#}  me and really see what was going on.

     However, I knew that as soon as I got my smart phone back I would be one of those {#blank#}10{#/blank#} once again. Perhaps I should just go back to using the basic phone and forget I ever got my smart phone back.

    Do animals have their culture? What do we mean by "culture"? Recent years social scientists have begun to ask if culture is found just in humans, or if some animals have their culture too. When we think of culture, we mean a way of life that a group of people have in common(共同的). Culture is the {#blank#}1{#/blank#} and beliefs(信仰) that a country or a group has. It is the way of behaviour that helps people live together. It is also the way of behaviour that makes a group of people {#blank#}2{#/blank#} other groups.

    Our culture makes us lose strength, claws(爪子), long teeth, and other defenses (防卫). Instead we use tools, cooperate(合作) with {#blank#}3{#/blank#}, and communicate with language. But this kind of "culture" can also be found in the lives of some animals. Animals can also make tools, for example. We {#blank#}4{#/blank#} think that the ability to use tools was the dividing line(分界线) between human beings and other animals. However, we have found that is not like this. Some animals can not only use tools but also make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.
