We produce lots of rubbish everyday. {#blank#}1{#/blank#} (take) away a city's rubbish is a big job. Every day trucks come into a city {#blank#}2{#/blank#} (collect) the rubbish. Most of it is made up of things we can't eat {#blank#}3{#/blank#} use. If we keep these things, we will have a mountain of rubbish soon.

    In some cities the rubbish. {#blank#}4{#/blank#} (carry) outside the city to a dump(垃圾场). The kitchen rubbish is broken into small pieces and sent into a sewage system(污水处理系统). {#blank#}5{#/blank#} sewage system takes away the used water {#blank#}6{#/blank#} toilets and other places.

    People usually use some earth to cover the dumped rubbish. Later, grass may be planted on the land. After all of these, the place looks much {#blank#}7{#/blank#} (clean) than before. With the beautiful environment in front of {#blank#}8{#/blank#} (we), it's hard to imagine that it used to be a rubbish dump. But actually it is not {#blank#}9{#/blank#} (health) to stay in such a place for a long time.

    In order to protect the cities, the rubbish is burnt in special places. The fire burns everything {#blank#}10{#/blank#} the metal. Sometimes the metal can be used again in factories. In those factories, the metal is made into different kinds of products.

    Swimming is very popular. People like swimming in summer {#blank#}1{#/blank#} water makes people feel cool. If you like swimming and swim in a {#blank#}2{#/blank#} / rɒŋ/ place, it may not be safe. These years, a lot of people lost their lives when they were enjoying {#blank#}3{#/blank#} (them) in the water, and most of them were students. But some people still don't take care {#blank#}4{#/blank#} themselves while swimming. They often think they swim so {#blank#}5{#/blank#} (good) that nothing can happen to them in water. Summer is here {#blank#}6{#/blank#} /əˈgen/.If you go swimming in summer, don't forget that {#blank#}7{#/blank#} /ˈbetə(r)/ swimmers have died in water. They died because they weren't {#blank#}8{#/blank#} (care), not because they can't swim. So don't get into water when you are alone. {#blank#}9{#/blank#} there is a "No swimming" sign, don't get into water. If you remember these, {#blank#}10{#/blank#} (swim)will be safer.

    A kiwi is a strange bird because it cannot fly. It has no wings or tail. It {#blank#}1{#/blank#} (not have) feathers like other birds. Its feathers look like hair. It {#blank#}2{#/blank#} (sleep) during the day and it smells things {#blank#}3{#/blank#} (good) than most birds do.

    The kiwi lives only in New Zealand and it's endangered(濒危的) now. Take the North Island brown kiwi for example. There {#blank#}4{#/blank#} (be) about 35,000 individuals left in the world. Many {#blank#}5{#/blank#} (animal), such as dogs, cats, and so on, threaten this beautiful, small bird. In some areas, most {#blank#}6{#/blank#} (kiwi) do not reach the age of breeding. So the brown kiwi population has gone down greatly.

    New Zealanders want their kiwis {#blank#}7{#/blank#} (live). The government says that people {#blank#}8{#/blank#} (can) kill kiwis. There is a picture of a kiwis on New Zealand money. Sometimes, people from New Zealand are called "kiwis".
