科目:初中英語 來源:2013屆江蘇省南京市白下區中考二模英語卷(帶解析) 題型:閱讀理解

Saving water is an important part of going green. As water becomes less and polluted more, conservation (保護) becomes more and more important. The less water you use, the less wastewater will end up in our rivers and lakes. Wasting water means that more water needs to be treated and cleaned, a process that requires quite a lot of energy.
As it is said above, cutting down on water usage is one of the most important things you can do for your local environment and the planet as a whole. That is why more green households are going blue: cutting down their water footprint by conserving and harvesting (收獲) water.
It may seem like a big concept, but going blue starts with small changes that everyone can make. Something as simple as turning off the tap while you brush your teeth can save a lot of water. Wash your fruits and vegetables in a bowl rather than under a tap to save even more. Make sure that the taps are fully turned off every time you step away from the sink or the shower — all those little drips can add up to a lot of water waste.
Another way of reducing your water footprint is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home’s water needs. Many of us already practice rainwater harvesting in a small way. Collecting water from your gutters (檐溝) is a great way to keep your garden green without running the sprinkler (灑水器).
【小題1】The underlined word “green” means ______ in this passage.

A.嫉妒B.環保C.未成熟的D.健康的
【小題2】According to the passage, which is NOT the reason that people should save water?
A.Treating wastewater needs much energy.
B.The water on the earth is becoming less and less.
C.The water on the earth is becoming polluted more.
D.Rainwater harvesting can meet a lot of your home’s water needs.
【小題3】According to the passage, all of these can be used to save water except ______.
A.washing fruit and vegetables under a tap
B.using a bowl to wash your fruit and vegetables
C.making sure taps are fully turned off all the time
D.turning off the tap every time after brushing your teeth
【小題4】Which of the following is the best title of this passage?
A.Save Water by Turning off the Tap
B.How to Treat and Clean Wastewater
C.Keep Your Garden Green with Rainwater
D.Save Water Starting with Small Changes
【小題5】From the passage, we can know that_____.
A.we can get enough water by harvesting
B.most people pay no attention to saving water
C.we can practice rainwater harvesting in a small way
D.harvesting water is more necessary than conserving it

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.
【小題1】Children like rainbows because          .

A.they are beautiful
B.they are like bows
C.they can find a pot of gold at the end of a rainbow
D.they are good to crops
【小題2】We cannot feel          with our hands.
A.a pot of goldB.a flowerC.a rainbowD.a raindrop
【小題3】We can see a rainbow          .
A.when it is raining heavily
B.when it is snowing
C.when it is cloudy
D.when it is becomes fine shortly after raining
【小題4】Which of the following statements is NOT true?
A.A rainbow is like bow.
B.A rainbow is the effect of light shining on raindrops.
C.Every rainbow has different colours in different orders.
D.A rainbow is one of the wonders of nature.
【小題5】The first colour of a rainbow is always           .
A.yellowB.redC.greenD.blue
