The population of the Earth is growing faster. It is important that we look after the Earth. We need it! The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!
【小題1】The Earth gives us ___________.
A.foodB.rubbishC.chemicalsD.pollution
【小題2】When something dies in nature, _________.

科目:初中英語 來源:2011年湖南省衡陽市中考英語試卷(解析版) 題型:閱讀理解

Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.

Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指紋) could be used to indentify the criminal.

Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands.

When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away.

Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使無菌) a surface just by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.

1.According to the passage,_______ could be used to identify the criminal.

A. fingerprints    B. scientists' hands

C. microbes        D. fingerprints and microbes on people's hands

2.Paragraph 3 tells us that________.

A. our hands look similar             B. the microbes will make the keyboard dirty.

C. we should compare hands often     D. we have our own sets of microbes.

3.When you work on computer, the microbes________.

A. just stay on our hands B. also stay on the keyboard

C. will do harm to you D. will disappear

4.From Noah Fierer we know that________.

A. fingerprints are no longer useful in fighting crime

B. microbes can be found on everyone's hands.

C. unlike microbe fingerprints can be cleaned if people wipe them

D. the microbe is used as a useful tool

5.What’s the best title of the passage?

A. Microbes May Tell Who You Are               B. Scientists Say Everyone Has Microbes
