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

We always say "Time is money", but time is even more precious(珍貴的)than money, because when money is spent , we can earn it back. But if time is gone away, it will never return. So, some of us even say time is priceless(無價的).
　　We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
　　As we all know , "Time and tide wait for no man." If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter .Remember: "No pains, no gains." Today's hard work is the cause of tomorrow's harvest.
