It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(压平)and melted (融化) and the melted things are made for new coke cans.
4. Recover
When you buy a box of apples, there may be a few rotten(腐烂的)apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society(社会). But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
小题1:_______ can be recycled.
A.Only hard things | B.Many things | C.Few soft things | D.All things |
A.to throw waste things away | B.to cover waste things with earth |
C.to get back the useful parts | D.to throw the whole things away |
A.China | B.Japan | C.Australia | D.America |
A.We will have no resources(资源) of nature unless we can do with the waste. |

D.More things are wasted in developed countries than in developing ones. |

Shopping in Singapore is really a pleasure for tourists. The Great Singapore Sale is held every year, usually during the summer months. Singapore’s famous shopping stores welcome a great number of visitors from all over the world. Their shopping hours last till midnight. During this time, nice and cheap goods are on sale for tourists to choose from. Tourists can also try delicious foods there and experience the Singaporean nightlife.

I wonder whether there is any girl or boy who does not like to see a rainbow in the sky. It is so beautiful.
There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. You could not find the pot of gold or its end. No matter how far you run, it always seems far away.
A rainbow is not a thing which we can feel with our hands as we can feel a flower. It is only the effect of light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see. It is called a rainbow perhaps because it is made up of raindrops and looks like a bow(弓).
That is why we can never see a rainbow in a clear sky. We see a rainbow only when there is rain in the air and the sun is shining brightly through the clouds.
Every rainbow has many colours in the same order. The first or the top colour is always red, and the next comes orange, then yellow, and last of all, blue. A rainbow is indeed one of the wonders of nature.

The hottest place in the world is the Sahara Desert in Africa. But there are deserts in many other places: in America, in Asia and in Australia. In 1917 the temperature in Death Valley, in the United States, was over 48°C every day for six weeks. That"s very hot!
But deserts are not always hot. After dark, deserts are very cold.
Not many animals and plants can live in a desert, because it doesn"t rain very often. But one animal likes the desert — the camel. It has big feet to walk on the sand. It can live for a long time without water. Sometimes it doesn"t drink anything for weeks — so it gets very thirsty! When it finds water it can drink 100 liters(升) at a time.

Canberra is the capital of Australia. It is a modern and lively city with a population of over 345 000.
History Canberra is the eighth largest city in Australia. It is 238 km from Sydney and 507 km from Melbourne. Melbourne was once the capital of Australia. Sydney people also wanted to make their city the capital. It was difficult for the government to make the decision. Then in 1911, the government chose a place to build the new capital. It was between Sydney and Melbourne, the two largest cities in Australia. It took more than 14 years to build the city. In 1927, the city was set up. It became the capital and was named Canberra. “ Canberra” means “a place for friends to get together”. |
Culture Canberra is a beautiful city with trees and flowers everywhere. There’s a Flower Festival in September each year. People can enjoy all kinds of beautiful flowers and welcome the spring to arrive. A man-made lake --- Lake Burley Griffin is in the center of the city. It’s about 25 km long. People like to ride bikes, walk or run around the lake. In Canberra, there’re many famous universities like the Australian National University and the University of Canberra. The National Library and the National Museum of Australia are also famous places that people like to visit. |

Antifreeze is a liquid(液体) that is added to water to keep it from freezing. When water freezes and turns to ice,it expands(膨胀).The force of water expanding is so great that it will break the hardest metal.Water is used in car engines(发动机) to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary.
Water freezes at 0℃;the usual kind of antifreeze will not freeze until the temperature is-40℃.A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at-18℃;four parts of water and five parts of antifreeze reduce this to -22℃.
Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol.
小题1:people use ________ to keep car engines cool.
A.antifreeze | B.water | C.alcohol | D.ethylene glycol. |
A.0℃ | B.-18℃ | C.-22℃ | D.-40℃ |
A.keep alcohol in water |
B.stop ice from becoming water |
C.make the freezing point of water lower |
D.raise the freezing point of water |
A.water | B.ethylene glycol | C.any chemical | D.any mixture |
A.tell us what antifreeze is |
B.make people buy antifreeze |
