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

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.''

A. Because she didn't want others to hear her play

Since the beginning of time, man has been interested in the moon. The Romans designed a special day to show admiration and respect to the moon. They called it “Moonday”, or “Monday”, as we know it today. Later, the great mind of Leonardo da Vinci studied the moon and designed a machine to carry a human to the moon. Leonardo said that one day a great machine bird would take a person to the moon and bring great honor to the home where it was born. Four and a half centuries later, Leonardo’s idea was realized. Apollo II took three Americans, Collins, Aldrin, and Armstrong to the moon. The mission (任务) did fill the whole world with great surprise, as Leonardo had said it would. Numerous essays, articles, and books were written about man’s first moon mission. But perhaps the most interesting story was one written before the event over 100 years before. In 1865, French author Jules Verne wrote a story about the first journey to the moon. His story was very similar to the 1969 Apollo II mission. Verne’s spacecraft also contained three men—two Americans and a Frenchman. The spacecraft was described as being almost the same size as Apollo II. The launch (发射) site in Verne’s story was also in Florida. The spacecraft in Verne’s story was named the “Columbiad”. The Apollo II command ship was called “Columbia”. His account of sending the spacecraft into the space could easily have been written about how Apollo II was sent into the space.
1.Leonardo da Vinci said that a great machine bird would ________.
A．bring great honor to the moon

A．100 years before the Apollo II mission
B．10 years before the Apollo II mission
C．four and one a half centuries ago
D．100 years ago
3.Verne’s story is very similar to _____.
A．the first U.S. space mission
B．the Apollo II mission
C．Leonardo da Vinci’s story
D．numerous other books on the same subject

From school to band practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes(电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
You’re having a blast at your friend’s birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera catches the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting (拍摄)whenever it hears that noise. That's one smart camera.

HOW would you like to step into the world of other people’s dreams? That’s just what Dom Cobb (Leonardo DiCaprio) does. His work is to steal secrets from people when they are asleep and dreaming. He has an even rarer ability: He can plant an idea in someone’s sleeping mind, and watch it grow and take root in reality. This ability is called inception.
The movie Inception (《盗梦空间》) was on show in Chinese cinemas not long ago. It is imaginative, of course. The movie leads one to wonder just how much we know about dreams. For years, scientists and researchers have been trying to solve sleep’s greatest mystery.
Is it possible to enter someone’s dreaming mind? In the movie, DiCaprio uses a drug and a dream machine to put a scenario (某一特定情节) into someone’s sleeping mind. He then goes to sleep himself, connected to the machine, and enters the other person’s dream.
In real life, there is a machine that can read someone’s mind. A brain scanner takes pictures of brain activity, and then the software recreates images of what the person was looking at.
Researchers say it may be possible one day to record someone’s dream – without the danger (or the fun) of actually sharing that dream.
What’s a dream, anyway? A dream is a group of images and sounds our brain creates when we’re sleeping. In the 1950s, researchers discovered a sleeping condition that happened around every 90 to 120 minutes during sleep: rapid eye movement, or REM. During this period you’re fast asleep, yet your eyes move around quickly under your eyelids (眼皮) and your brain is nearly as active as during the day. That’s when most dreams happen.
What do dreams mean? Dreams are not always filled with meaning. Sometimes dreams are just your mind playing with thoughts and images from your life, or things you may have read or seen on TV. But at other times, dreams show things that you want to achieve in real life, or things that cause you trouble or stress.
1.The movie Inception is mentioned at the beginning of the article to ______.
A. encourage readers to watch the movie
B. tell readers about people with special dreaming abilities
C. inform readers about the science of dreams
D. warn reader about the threat of dream stealers
2.According to the article, how does a brain scanner work?
A. It records dreams.
B. It uses a special drug that causes no pain.
C. It finds out what dreams mean.
D. It takes pictures of brain activity and recreates images.
3. According to the article, which of the following statements about REM sleep is TRUE?
A. Most dreams occur in REM sleep.
B. Over the last ten years scientists have solved the mystery of REM sleep.
C. People always remember what they have dreamed in a REM sleep.
D. People can have REM sleep all night.
4. The article claims that ______.
A. dreams tell us a lot about a person’s character
B. dreams are connected to real life
C. dreams are useful and help keep our brains active
D. dreams are usually about meaningful things
