A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.
An electromagnetic field(电磁场) will pull particles(微粒) in the smog to the ground where they can be easily cleaned.
“It’s like when you have a balloon which has static(静电) and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.
His studio has reached an agreement with the Beijing government to test the technology in one of tile capital’s parks.
With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.
Roosegaarde says an indoor model device has already proven it works and is confident that the results — with the help of a team of scientists and engineers — can be replicated(复制的) outside.
“Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”
“We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”
Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem,rather than a practical solution to Beijing's awful air pollution.
“This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”
However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.
1.The device works by _______.
A. helping keep the particles out with more masks
B. pulling pollutants to the ground with an electromagnetic field
C. absorbing hair with a balloon with static
D. creating clean air and let it out into the sky
2. According to the passage,_______ .
A. the Beijing government has agreed to use the technology in Beijing
B. they have proven the results of the device both indoors and outdoors
C. the results of the air-cleaning device can be expectable
D. the Beijing government has never done anything to handle the air pollution
3.What does Roosegaarde really mean by saying “Beijing is quite a good place... ”?
A. The air pollution in Beijing is not quite serious.
B. The weather in Beijing is good for foreigners to live in.
C. Beijing is quite fit for using the air-cleaning device.
D. It is easy to get the top of the smog in Beijing.
4.Roosegaarde appeals to people in Beijing to ________.
A. pay attention to air pollution and solve the problem finally
B. invent more devices to clean the smog in Beijing
C. drive modern cars and try different lifestyles
D. realize how serious the pollution they're facing is

Dutch designer Daan Roosegaarde has spent much of his time seeking artistic solutions(解决方案)to solve our environmental problems. His past projects include "Bioluminescent(生物发光)Trees" to light streets, a "Smog-Free Tower" to clean Beijing's polluted air. and "Gates of Light". which uses the headlamps of passing cars to light up the 60 floodgates of the Afsluitdijk, a major dam in the Netherlands. Now, he is hoping to use his skills to solve a pressing global problem-space junk!
Scientists guess that there are over 500,000 bits of large rubbish. To deal with the problem, Roosegaarde intends to achieve his goal by educating the public about the need of the situation and coming up with possible solutions. The plan. called the Space Waste Lab. started in October 2018 with a laser(激光)show in the Netherlands. The unique outdoor artwork of LEDs used real-time tracking information to point at pieces of space junk floating at altitudes of 200 to 20,000 kilometers. The experience was designed to make the public know more about how much space junk there are.
To find a solution, the designer has been thinking with experts. One of the projects being considered is "Shooting Stars",which attempts to reintroduce the trash to the atmosphere in a controlled way. Upon reentry. the waste would burn in the atmosphere like a shooting star. Roosegaarde envisages that if successful .burning space trash could someday replace fireworks at large public events!
In September 2018。the RemoveDEBRIS satellite successfully sent a net to catch a target while orbiting at an altitude of about 300 kilometers(190 miles). Sometime this year. the capsule will set free a harpoon that has been designed to remove space trash. At the end of its task,RemoveDEBRIS will let go a sail to bring the satellite itself and hopefully some trash, back into the atmosphere where it will burn up.
1.What can we infer about Daan Roosegaarde?
A.He is too aggressive to put forward good plans.
B.He is creative in solving environmental problems.
C.He is fond of spending all of his time seeking art skills.
D.He is sensitive to art reflected in environmental projects.
2.Why was a laser show held in October 2018?
A.To confirm real-time information about space trash.
B.To show the great beauty of LEDs to common people.
C.To raise public awareness of the amount of space trash.
D.To inspire people to consider the solution to space trash.
3.What does the underlined word "envisage" in paragraph 3 probably mean?
A.Suspect. B.Demand.
C.Advise. D.Imagine.
4.What is the function of a sail?
A.Bringing the satellite to atmosphere to burn.
B.Keeping trash traveling along its own orbit.
C.Taking the satellite away from atmosphere.
D.Removing space trash out of the capsule.

Facebook has taken over a start-up named CTRL-Labs, which is developing devices that can pick up electrical signals from the brain and transmit them to a computer. CTRL-Labs has designed a wristband that can identify the signals the brain sends to the hand telling it to move, and decode (解码) them. It could then transmit that command — for example, to press a button — to a computer or other devices.
It also captures (捕捉) your intention”, said Facebook VR president Andrew Bosworth. “So you can share a photo with a friend using an imperceptible (极细微的) movement or just by, well, intending to,” he said in a post on his personal Facebook page.
Facebook has not confirmed a report by CNBC which claimed that the deal was worth between $500 m and $ l bn (£0.4bn and £0.8bn).). Mr Bosworth said he hoped the CTRL-Labs team would help Facebook to “build this kind of technology, at scale and get it into consumer products faster”.
There was a mixed response to the news.
“Facebook needd to leave us alone. Step away from our lives more.” tweeted tech commentator Azeem Azhar.
“I’m very curious to see what the response is from regulators here,” wrote an analyst Fatemeh Khatibloo.
Underneath Andrew Bosworth’s Facebook post, Josh Chan, founder of an educational app, said the news was exciting.
“As an educator, I’m imagining how this could transform how we all learn,” he said.
Facebook implied it would be some time before the product came to market. “The CTRL-Labs technology is an innovative input that Facebook hopes will be used to significantly improve the upcoming Facebook VR experiences a few years down the road to fundamentally improve the user experience.” it said.
Facebook may have more to say about the new acquisition on Wednesday at its annual VR headset event, which the firm purchased in 2014 for around $2bn.
1.What does the underlined sentence imply?
A.Facebook should not affect people’s lives any more.
B.Facebook should get less involved in people’s lives.
C.Facebook should be less concerned about people’s lives.
D.People’s lives have been totally disturbed by Facebook.
2.What is the author’s attitude towards CTRL-Labs?
A.Positive. B.Negative. C.Objective. D.Indifferent.
3.What does the passage mainly talk about?
A.The acquisition of a start-up company that has designed a fancy wristband.
B.The design of a high-tech product that can greatly affect people’s lives.
C.The development of a wristband that can capture users’ intentions.
D.The purchase of a start-up company that is developing a mind-reading product.

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石),mammoths and mastodons, the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .”
1.One of the fossils studied by the researchers is that of ________.
A. the Asian elephant B. the forest elephant
C. the savanna elephant D. the mastodon elephant
2.The underlined word “divergence” in paragraph 4means “________”
A. evolution B. exhibition C. separation D. examination
3.The researcher’s conclusion was based on a study of the African elephant’s _____
A. DNA B. height C. weight D. population
4.What were Alfred Roca’s words mainly about?
A. The conservation of African elephants.
B. The purpose of studying African elephants
C. The way to divide African elephants into two units
D. The reason for the distinction of African elephants
5.Which of the following can be the best title for the passage?
A. Naturalist’s Belief about Elephants.
B. Amazing Experiment about Elephants
C. An Unexpected Finding about Elephants
D. A Long scientific Debate about Elephants

Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子),but it’s not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.
This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.
On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it’ll try to get nice photos of those faces,” said Juston Payne, the device’s product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child’s hand is over the lens, or if it is tossed in a dark purse.
The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.
Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.
“This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we’re likely to get more assistance from the artificial intelligence packed into our apps and gadgets.
1.What is the most outstanding feature of Clips?
A. It allows of hands-free photography. B. It enables easy internet access.
C. It is equipped with tough glass. D. It can be worn on your clothing.
2.What does the underlined word “candid”, in Paragraph 2 mean?
A. touching. B. brief C. unforgettable. D. embarrassing.
3.What makes Clips a reality according to Juston Payne?
A. The advance in technology. B. The popularity of the Internet.
C. The rise of the smartphone industry. D. The reduction in the price of lens.
4.What is the best title for the text?
A. Artificial Intelligence in Everyday Life. B. New Gadgets in the Age of Apps.
C. A New Digital Camera from Google. D. An Alternative Way to Photograph.
