In order to know a foreign language thoroughly, four things are necessary. Firstly, we must understand the language when we hear {#blank#}1{#/blank#} spoken.. Secondly, we must be able to speak it correctly with confidence and without hesitation. {#blank#}2{#/blank#} ,we must be able to read the language , and fourthly, we must be able to write it. We must be able to make sentences that are grammatically correct.

    There is no easy way to success {#blank#}3{#/blank#} language learning. {#blank#}4{#/blank#} good memory is of great help, but it is not enough only {#blank#}5{#/blank#}(memorize) rules from a grammar book. It is not much use learning by heart long list of words and {#blank#}6{#/blank#}meanings , studying the dictionary and so on. We must learn by using the language. {#blank#}7{#/blank#}we are satisfied with only a few rules we have memorized, we are not really learning the language. “Learn through use” is a good piece of {#blank#}8{#/blank#}(advise) for those {#blank#}9{#/blank#}are studying a new language. Practice is important. We must practise speaking and {#blank#}10{#/blank#}(write) the language whenever we can.

Using Garbage as a Fuel

    Garbage can be a good fuel to use. The things in garbage do not look {#blank#}1{#/blank#}coal, petroleum, or natural gas, but they are chemically similar to these fossil fuels. As we use up our fossil fuel supplies, we might be able to use garbage as {#blank#}2{#/blank#}energy source. Burning garbage {#blank#}3{#/blank#}( be) not a new idea. Some cities in Europe and the United States {#blank#}4{#/blank#}(burn) garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby {#blank#}5{#/blank#}( build). In Paris, France, some power plants burn almost 2 million metric tons of the city's garbage each year. The amount of energy {#blank#}6{#/blank#}(produce) is about the same as would be produced by burning almost a half million barrels of oil!

    But there are problems in using garbage as a fuel. Garbage that burns {#blank#}7{#/blank#}(easy) , such as food and paper, must be separated from metals, glass, and other materials {#blank#}8{#/blank#}do not. Another problem is that burning garbage can pollute the air. Our fossil fuel supplies are {#blank#}9{#/blank#}(limit) . Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage {#blank#}10{#/blank#}(pile) up on the earth.

    We high school students do have some growing pains, but we can get rid of them{#blank#}1{#/blank#} (correct) and wisely. First, some of us are upset about our body style and looks. It's unnecessary and it's not important at all. We needn't care about it. It is one's inner beauty that{#blank#}2{#/blank#} (matter). Second, we sometimes seem to be misunderstood by our teachers, parents and classmates. Faced with this, we can find a proper time to have a heart-to-heart talk with them, trying to remove the misunderstanding. Some of us have fewer friends, I think being open-minded and friendly will do us good. Third, we may fall behind others, {#blank#}3{#/blank#} makes us stressed. Actually we can encourage{#blank#}4{#/blank#} to work efficiently, full of{#blank#}5{#/blank#} (determine). At last, some of us don't have much pocket money, so they feel unhappy. Isn't it strange? So long as we have some, that's enough. And we can learn how to spend money.

    John Snow was a famous doctor in London-so{#blank#}1{#/blank#},indeed,that he{#blank#}2{#/blank#}Queen Victoria as her personal physician. But he became{#blank#}3{#/blank#}when he thought about helping ordinary people{#blank#}4{#/blank#}to cholera.This was the deadly disease of its day.Neither its cause nor its{#blank#}5{#/blank#}was understood.So many thousands of terrified people died every time there was an outbreak.John Snow wanted to face the challenge and solve this problem.

    First there was England.Wales was{#blank#}6{#/blank#}to it in the thirteenth century.Now when people{#blank#}7{#/blank#}to England you find Wales{#blank#}8{#/blank#}as well.Next England and Wales were joined to Scotland in the seventeenth century and the name was changed to "Great Britain".Happily this was accomplished without{#blank#}9{#/blank#}when King James of Scotland became King of England and Wales as well.Finally the English government tried in the early twentieth century to form the United Kingdom by getting Ireland{#blank#}10{#/blank#}in the same peaceful way.
