C 节约用水 说明文 ☆☆☆☆☆ 9分钟
Did you know that people can only use less than 1% of all the water on the earth? And we can't drink the rest, wash with it, or use it to water plants. So it is important that we use our water wisely and don't waste it.
There are many simple things we can do to save water.
• Turn off the tap(水龙头). Just by turning off the tap while you brush your teeth in the morning and before bedtime, you can save up to 8 gallons of water! The same is true when you wash dishes. Turn off the tap! Put the plates in the dishwasher(洗碗机).
• Take a shower instead of filling up a bathtub(浴缸). It uses much less water. To save even more water, keep your shower under five minutes long—try timing yourself with a clock next time!
• Fix the leak(裂缝). If your toilet has a leak, you could be wasting about 200 gallons of water every day. That would be like flushing(冲洗) your toilet more than 50 times for no reason!
• Water your yard in a clever way. The best time to water your yard is in the early morning or late evening when it's cool outside. Also, when you're helping your parents water the yard, make sure not to water the plants too much—remember that a little sprinkle goes a long way!
• Who needs a hose(软管)? Washing your bike or car with a bucket and sponge instead of a hose saves a lot of water. A hose can waste 6 gallons per minute if you leave it running, but using a bucket and sponge only uses a few gallons!

【短文大意】水是生命之源，但是大自然的水能被我们利用的却很少。所以，我们应该从自身做起，节约用水，如关上水龙头、选择淋浴、修理漏水的马桶等。
1. A 【解析】段落大意题。第一段的“So it is important that we use our water wisely and don't waste it.”是本段的中心句，告诉我们节约用水的必要性。
2. C 【解析】推理判断题。由第三段的“Just by turning off the tap...you can save up to 8 gallons of water!”可知，如果吉姆在早晚刷牙时关掉水龙头的话，他就可以节约8加仑的水。
3. B 【解析】推理判断题。由第三段的“Put the plates in the dishwasher.”可知，用洗碗机洗餐具是一个节约用水的好习惯。
