The world uses plenty of water a day. Drinking water is a human right and everyone should have【小题1】（they）share. However, more than 700 million people around the world have trouble【小题2】（get）clean, safe water.

And it also helps the environment【小题4】keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans.

Then desalination（海水淡化）businesses come in. More than 19,000 factories have been built around the world, 【小题7】（most）in coastal countries. Every day, they process more than 92 million tons of water. But the technology they use【小题8】（require）a lot of energy.

Scientists【小题9】（work）to create a technology that costs less money and works better. They want to produce 20 times more clean water, 【小题10】make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

Each student needs to learn something different. Pleasure reading makes it p【小题8】 for each student to learn what he or she needs.

Reading for pleasure is not the same as studying. When you read for pleasure, you choose your own books, and you d【小题9】 have to remember everything. There are no tests on your pleasure reading books. Pleasure reading will help you:

November 9 is National Fire Safety Day in China. What should you do if there 【小题1】 a fire?

Get help from your parents or 【小题2】 119. Don’t try to put out a 【小题3】 by yourself.

Get out of the room 【小题4】 soon as possible. If there’s a lot of smoke in your room, stay close to the floor. It’s easier to breathe (呼吸) there and see things.
