Our environment isn’t as green and beautiful as it should be. There are steel(钢铁)monsters blocking out the sun，blowing out dangerous smoke，and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way, and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth．

You can see many big garbage dustbins in the streets．They’re not there for a show, but for you to drop your waste．We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “accidentally” drop as yon walk down the street, ask yourself how ranch waste you’re been contributing to the environment with that bad habit going on for years.

At home；the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps(水龙头)are not leaky(泄漏的)，which would help greatly in scrimping. Another is to use energy-saving lights，and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs．

Recycling is a method to make items reusable．Many things you want to throw out can be made into new products through the reproducing process．Use your imagination to come up with ways on things that you can use again．

Pass on the message of simple ways to save the environment to kids. Starting with kids is a good way of teaching the message early in their lives，in the hope that they can carry it forward as they grow older．

With environmental protection awareness(意识)in mind，we can do what we can，for the results are to have a big effect on the planet．As long as we do our part，the world is one small step closer to being saved.

71. In the first Para the author uses “steel monsters” to describe

A．big factories B. huge buildings

C. high mountains D. characters in fairy stories

72．The underlined word “scrimping” in the third Para can be replaced by

A．cleaning B. cooking C. saving D．drinking

73．From the Fifth Para，we can know that

A. protecting the environment begins with small chores

B. protecting the environment should start from childhood

C. wonderful life comes from environmental protection

D. protecting the environment benefits the country and the people

74．Which of the following is NOT TRUE?

A. The more people do their part, the greener the environment will be

B. Selling what you dent want any more is a kind of recycling

阅读理解

　　Meteorites (陨石) are lumps of rock and iron that hit Earth from outer space. Some of them are almost solid iron. We don’t know for sure, but the first iron that men used for tools and weapons might have come from meteorites. Iron is much heavier than most rooks. Early man would have noticed this.

　　It is thought that the centre of Earth is almost all iron, like the meteorites. But iron found on Earth’s surface is mixed with other things. Rock with lots of iron in it is called iron ore (铁矿石).

　　Iron ore is found in many places on Earth. There is much of it in Canada, but there’s a lot more of it in the United States—near Lake Superior (苏比利尔湖). Ships carry iron ore across Lake Superior and the other Great Lakes to steel mills in such cities as Chicago, Pittsburgh, and Detroit.

　　Steel is iron that has something called carbon in it. The carbon helps make the steel very hard. At first, steel was made by hammering heated iron on an anvil (铁砧) with a little carbon dust. Then a hundred years ago, Henry Bessemer in England and William Kelly in America discovered a better way of making steel. They made it in a big container called a crucible (坩埚). They loaded the crucible with hot melted iron and carbon and had air blown through it from the bottom. A few years later a still better way of making steel was discovered. It was called the open-hearth method (平炉炼钢法). And a lot of steel is still made in this way.

　　For making certain special kinds of steel, where the heat and the chemicals must be measured very carefully, an electric furnace is used. Recently, still another way of making steel was discovered. This is really an improvement on the openhearth way. Oxygen gas is blown into the hot melted iron at the top of the giant furnace.

　　Most steel is carbon steel. This is the kind of steel that is used in making such things as bridges, automobiles, boilers, ships, and railroad tracks.
