Has the world just witnessed its first ever robot suicide（自杀）?
Tiring housework was seemingly too much for one cleaning robot to take，when it apparently rebelled（反抗） and decided to end it all.
The robot was given the tiresome task of cleaning up some spilt cereal（残渣剩饭） before it climbed on to a kitchen hotplate where it was destroyed，according to reports in Austria.
It had reportedly grown worn out of being forced to clean the same house every day and decided to become a victim to the robot cause.
“Somehow it seems to have restarted itself and made its way along the work surface where it pushed a cooking pot out of the way and basically that was the end of it,”explained fireman Helmut Kniewasser，who was called to handle the fire.
“It pretty quickly started to melt and then stuck to the kitchen hotplate. It then caught fire. By the time we arrived，it was just a pile of ash.”
The fireman added: “The entire building had to be evacuated（疏散） and there was severe smoke damage particularly in the flat where the robot had been in use. It's a mystery how it came to be started and ended up making its way to the hotplate. ”
It took an hour to clean and make the building safe. The homeowner plans to sue（控告） the producer of the robot.

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 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.
C. The robot's producer.

“This is not the real answer for smog. The real answer has to do with clean cars，different industry and different lifestyles.”

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 48. 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
49. 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.

The intelligence times provide us much convenience，but at the same time，some of our abilities are being weakened gradually.
1. Memorizing phone numbers
It was annoying to remember numbers. Now we simply add them to our contacts list. That usually works well unless our device is lost，stolen，or damaged. No one can be expected to remember all their contact numbers. What we can do is memorize 5 of our most important contact numbers. This should include a mixture of family，friends and business. If you're really ambitious you can memorize 5 contacts for each category.
2. Map-reading skills
The convenience and effectiveness of GPS guidance systems and digital maps generated by search engines is unquestionable. They've definitely made our lives easier. What we don't get from using these devices and applications is the increased ability to understand spatial orientation（空间方向）and navigation.
To renew or acquire those skills，try using physical maps to plan your next trip. After a few trips，you'll be pleasantly surprised with how useful a physical map can be.
3. Photography
Even amateur photography requires a basic learning about lighting，depth，and composition. This is true for digital photography. Most smart cameras automatically make these adjustments. We no longer have to learn the art of photography. On most devices，this is easily changed by turning off the automatic settings. Experiment with setting by hand the scene modes，lighting，and zoom. You just may learn that you're a “true photographer”.
4. Reading comprehension
The primary cause is E-reader. They're convenient and can store thousands of books. But there's evidence that E-reader makes it more difficult for readers to keep and recall information they just read. Don't worry! What we should do is make an effort to read printed books. This will be especially helpful when seeking information we need for academic or career purposes.
5.Hand-written correspondence（通信）
Writing letters and notes include hand writing skills，organizational skills，and learning about the person or persons you correspond with. This is another easily regained skill. Send a letter to an old friend，relative or acquaintance.
53. What's the disadvantage by adding all numbers to the contacts list? A. We might lose all our phone numbers accidentally. B. It's hard to find the number from the contacts list.

56 .E-readers are thought to weaken our reading comprehension because ______. A. they are convenient and can store thousands of books B. they make it more difficult for us to recall information C. less people can afford to buy E-readers
