The polar bear is a vein big white bear. We call it the polar bear {#blank#}1{#/blank#} it lives in the Arctic Circle near the North Pole.

    The polar bear lives in snow and ice. At the North Pole there {#blank#}2{#/blank#} (be) only snow, ice and water. There is not ally land. The polar bear has a very {#blank#}3{#/blank#} (warmly) coat because the weather is cold in the Arctic Circle.

    You can't find the polar bear easily in the snow because {#blank#}4{#/blank#} coat is white.

    A grown-up polar bear is usually about three meters long and weighs 450 kilos. It can stand up on its back legs because it has very wide {#blank#}5{#/blank#} (foot). It can use its front legs like arms. The polar bear can swim very {#blank#}6{#/blank#} (good). It catches fish and sea animals for food. It goes into the sea when it is afraid. People like to kill the polar bear {#blank#}7{#/blank#} its beautiful white coat. The government of Canada and {#blank#}8{#/blank#} United States call on that people should stop {#blank#}9{#/blank#} (kill) polar bears. They don't want these beautiful animals to {#blank#}10{#/blank#} (death) out.

    Many people think that the dinosaurs(恐龙) were the biggest animals that ever lived. They are wrong. The world's biggest animal is still living, and it lives in the sea. It is called the Blue Whale, Blue Whales can be as long as 30 meters {#blank#}1{#/blank#} weigh as much as 1,000 kilos. The largest dinosaurs {#blank#}2{#/blank#} (weigh) only 500 kilos.

    The whale is not only the world's biggest animal, it is also one of the {#blank#}3{#/blank#} (clever). We know that whales can communicate with one{#blank#}4{#/blank#} (other), although we do not know what they are saying. One day perhaps we will learn to talk to whales, and then they will be able to tell us about {#blank#}5{#/blank#} (they).

    There are lots of stories {#blank#}6{#/blank#} whales, and maybe the most famous one is called Moby Dick, which was {#blank#}7{#/blank#} (write) by the American writer, Herman Melville. In this story, a sailor ——Captain Ahab spends a lot of time trying to find and kill{#blank#}8{#/blank#} very big white whale named Moby Dick. {#blank#}9{#/blank#} (Sad), there are not many kinds of whales left. People have killed them for {#blank#}10{#/blank#} (thousand) of years for food and other things. However, there are now laws(法律) to stop people killing most kinds of whales, so perhaps there will be more of them in the years to come.

    It is necessary to relax ourselves after the exam. There are some kinds of{#blank#}1{#/blank#}(activity) for us to take part in. First of all, we can go for a w{#blank#}2{#/blank#} along the bank of the river. We can also go to the movies or listen to music. What's more, joining in a sports club is a good {#blank#}3{#/blank#}(choose), which can keep us healthy. For example, p{#blank#}4{#/blank#} football in the afternoon may relax ourselves. Above all, we should arrange(管理) our time{#blank#}5{#/blank#}(proper) and live a regular(规律的) life. I hope all of us can have a wonderful time.

    "Thank you" is widely {#blank#}1{#/blank#}(use) in the modern society. It is a very good manner. You should say "Thank you" {#blank#}2{#/blank#}others help you or say something kind to you. For example, when someone {#blank#}3{#/blank#}the door for you, when someone says you have done a good job, when someone says you have {#blank#}4{#/blank#}(buy) a nice shirt, or your city {#blank#}5{#/blank#}

very beautiful, you should say "Thank you". "Thank you" is not only used between friends, but also used {#blank#}6{#/blank#}parents and children, brothers and sisters, husbands and wives.

    "Excuse me" is {#blank#}7{#/blank#}(other) short polite usage. We use it as often as "Thank you". When you hear someone say so behind you, you'd get to know that somebody wants to walk past you without {#blank#}8{#/blank#}(touch) you. It is not polite to interrupt(打断) others while they {#blank#}9{#/blank#}(talk). If you want to have a word with one of them, please say "Excuse me" {#blank#}10{#/blank#}(one), and then begin to talk. You should also do so when you want to cough or make any unpleasant noise before others. Let's say "Thank you" and "Excuse me" on the right occasion.
