题目内容
A machine which makes water out of air could become the greatest household invention since the microwave. Using the same technology as a dehumidifier (除湿器), the Water Mill is able to create a ready supply of drinking water by getting it from a limitless source-the air. The company behind the machine says not only does it offer all alterative to bottled water in developed countries,but it is a solution for the millions who face a daily water shortage.
The machine works by drawing in damp air through a filter(过滤器) and over a cooling element which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the humidity(湿度)in the air increases.In keeping with its ecodevelopment,the machine uses the same amount of electricity as three light bulbs.
Inventor Jonathan Ritchey said:“The demand for water is off the chart.People are looking for freedom from water distribution systems that are shaky and unreliable”.
The machine,which is about 3 feet wide,is likely to cost£800 when it goes on sale here in the spring.Its maker, Canadian firm Element Four, estimates that a liter of water will cost around 20 pence to produce.
Environmentalists claim half the world’s population will face water shortage because of climate change by 2080.One in five humans is said to lack access to safe drinking water.
The Water Mill is not effective in areas with below about 30 percent relative humidity, but with average relative humidity in England of more than 70 percent that won’t be much of an issue here.
1.According to the author, the biggest advantage of the machine is its ______.
A.little power use B.unlimited source C.proper size D.high production
2.We can conclude from the passage that the machine________.
A.can be used everywhere
B.has not been on sale
C.will replace the water distribution system
D.will solve the problem of water shortage
3.The underlined phrase “off the chart” in the passage means ________
A.record-breaking. B.urgent. C.unbelievable.D.amazing.
4.What would be the best title for this passage?________
A.Microwave for Household Use B.Filter to Draw in Damp Air
C.Mode Dehumidifier on Sale D.Machine to Make Water out of Air
1.B
2.C
3.B
4.D
【解析】
试题分析:文章大意:本文介绍了一项新发明:从空气制水的神奇的机器。
1.细节理解题。由第一段可知,该发明最大的优点是空气取之不尽用之不竭。 B
2.细节理解题。由第四段“The machine,which is about 3 feet wide,is likely to cost 800 when it goes on sale here in the spring”可知,该发明将取代水分配系统。选C
3.猜词题:从第三段的句子:People are looking for freedom from water distribution systems that are shaky and unreliable”.可知人们在寻找一种方法摆脱不可靠的水分配系统,所以对水的需求是很紧急的,“off the chart”=urgent,选B。

考点:考查科普类短文
Brenda Bongos was a happy, artistic girl. She had one big ambition—to play the drums in a band. But one big problem lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.
One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.
With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit(成套设备) and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.
It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.
Years later, when asked how she had achieved all this, she thought for a moment, and said: ''If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.''
1.Why did Brenda try to play in the strangest places?
A. Because she didn't want others to hear her play
B. Because she didn't mean to disturb others.
C. Because she didn't have her own room
D. Because she didn’t like her neighbors.
2.Brenda started to give concerts _______.
A. after she practiced in her space bubble
B. when she became part of the unique space journey
C. after she became a real musical astronaut
D. when people came to see her in the space bubble
3.Brenda became famous because _______.
A. she was good at music and science
B. she became a real musical astronaut
C. she invented a special way of practice
D. she played well and had a talent
4.Which of the following can be used to describe Brenda?
A. Kind, hardworking and clever
B. Brave, kind and hardworking.
C. Lovely, brave and kind
D. Nervous, kind and clever.
5.It can be inferred from the text that: " _______".
A. He laughs best who laughs last
B. It's never too old to learn
C. Two heads are better than one
D. One good turn deserves another
