题目内容
If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA(美国航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(细菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.
【小题1】NASA will use a high-tech machine to recycle wastewater at the ISS to ______.
| A．protect the ISS |
| B．make the astronauts work harder |
| C．provide better water and food for the astronauts |
| D．save the cost of sending water up to the ISS |
| A．4.4 thousand | B．11 thousand |
| C．48.4 thousand | D．24 million |
| A．freezing | B．heating |
| C．shaking | D．precipitating(沉淀) |
| A．water recycling at the ISS |
| B．the International Space Station |
| C．a high-tech machine |
| D．the cost of NASA |
| A．The recycled water is much better than that from a city tap. |
| B．The high-tech machine will recycle all the water used on the station. |
| C．The ISS astronauts use more water than us. |
| D．The high-tech machine can only recycle urine to make water. |
【小题1】Ｄ
【小题2】Ｃ
【小题3】Ｂ
【小题4】Ａ
【小题5】Ａ
解析试题分析：这篇短文主要描述了在空间站上水的回收利用问题。科学家们用一种高科技机器把人员在空间站上产生的废水，回收利用，从而减少往空间站运水的费用。
【小题1】根据短文第一二段描述，可知选Ｄ，用高科技机器来节约送水去空间站的花费。
【小题2】根据第三段描述，计算可知11,000*4.4=" 48.4" thousand，故选Ｃ。
【小题3】根据最后一段The water will be heated to 130℃ to kill bacteria(细菌).描述，可知选Ｂ。
【小题4】这篇短文主要描述了在空间站上水的回收利用问题。故选Ａ。
【小题5】根据最后一段Scientists say that the recycled water is thousands of times better than the water from a city tap.描述，可知选Ａ。
考点：关于水的回收利用问题的说明文阅读
点评：本文信息量较大，出现数字较多。阅读中注意把握短文的重点内容。然后带着问题,再读短文,找出答题依据.对于有关数字的问题,要认真分析,并进行必要的计算.
Get SMART This Year
| interest however take monthly weight week start will they new |
If you’re one of 3 , you’ll be more successful if you make SMART goals! Each goal should be:
Specific. Don’t say you want to lose some 4 , read more or exercise. Decide how much weight to lose, how many books to read, or how many times a 5 to exercise.
Measurable(可衡量的). Weigh yourself daily, count the number of books you read 6 , and make notes of how many times you exercise each week.
Attainable(可达成的). Don’t set impossible goals. For example, don’t make promise to lose 10 kilograms in a week. Or if you have just 7 running, realize you won’t be running a long-distance race in a month.
Relevant(相关的). If you love history, you probably 8 read eight books a month about science. You won’t stick with it if the subject isn’t 9 .
Timely. Set deadlines. How long will you 10 to read a book?
A new year is about starting over--- so start now!
