The next time a giant Big Mac or Coke flashes...

The next time a giant Big Mac or Coke flashes into your mind when you’re walking home from the pub, you may not simply have the snacks. And that picture of the model putting on Chanel — no, you’re not daydreaming.

A British startup has created a new advertising system that uses lasers to project images up to 200 metres tall from the sides of tall buildings, enabling advertisers to reach people from virtual billboards（广告牌）in the sky. Passers-by will see each image for only between one tenth and quarter of a second, as their eye eye catches the light from certain angles.

Advertising agencies and big businesses have already signalled their interest, but Skyline campaigners have branded the technology “greedy” and said that it could fill our skies with showy and tasteless brands.

The Echo system, from Lightvert, uses a high laser projector to bounce light off a narrow reflective strip fixed to the side of a building, visible up to 1km away. This creates large-scale images that are captured briefly in the viewer’s eye as a result of the “persistence of vision” effect: the same effect that leaves an imprint of a light source on your vision after you’ve turned away.

Daniel Siden, the technology’s inventor, explained: People often think this could be subversive, but it’s not subliminal advertising（隐性广告）as the imagery registers on the conscious level. It’s actually less invasive and more fun than traditional advertising. Mr.Siden said that planning experts have indicated that planning permission should not be a problem outside of conservation area. He said that the system was safe because of the distance between the projector and passers by. And images would be above the line of sight of drivers and cyclists

and below the field of vision of airline pilot. The images have been tested and shown not to cause epileptic seizures（癫痫发作）.

Because it uses only one strip of reflected light, the system needs a small amount of the power, about one-twentieth of a standard 96-sheet digital outdoor display for an image of the same height.

The owners of high-rise properties could use the system to make large returns from installing the laser projector and reflective strip. The company puts the cost of a unit measuring 100 metres at under ￡750,000, based on the present design, anticipating that costs will drop.

Still, some Skyline campaigners dislike the technology and believe it delivers subliminal advertising. Barbara Weiss of the Skyline Campaign, said: “It’s actually offensive. London’s latest tall buildings are not particularly well-built or well designed, but unfortunately people are forced to look at them. Adding stupid advertising that’s invasive in its nature will only make it worse.”

1.Why does the writer cite the example of Big Mac, Coke and Chanel in paragraph 1?

A.Because he attempts to promote these products to potential consumers.

B.Because he studies the association between products and images in advertising.

C.Because he tries to illustrate the effectiveness of flashing images of advertised goods.

D.Because he wants to introduce a new advertising technology to readers.

2.Which of the following statements about the Echo system is true according to the passage?

A.Pedestrians can see the flashing images on one side of the building from specific angles.

B.The system is composed of a laser projector, a reflective strip and a physical billboard.

C.The image lasts between one tenth and quarter of a second in vision even if you turn away.

D.It’s a new advertising system developed by a time-honored British company.

3.The underlined word “subversive” in paragraph 5 probably means ________.

A.Subconscious B.trouble making

C.harmless D.imaginative

4.Which party is likely to set obstacles to the application of the Echo System?

A.Environmentalists worried about energy consumption.

B.Drivers, cyclists and pilots whose sight might be affected.

C.The Skyline Campaign regarding the image as flashy.

D.The patients who suffer from epileptic seizures.

Next time you raise an eyebrow at the views of your friend, brother, sister or colleague, remember they could be helping to make you smarter. New research shows that intelligence is not fixed but can be improved throughout adulthood by family members, bright mates and intellectually challenging careers. The study challenges the commonly held belief that intelligence is fixed by the age of about 18.

Scientific consensus (共识) suggests intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a part up to this age. After this point, IQ scores become steady. But James Flynn, professor at the University of Otago in New Zealand, argues that people can “upgrade” their intelligence throughout their lives. He believes intellectual stimulation (刺激)from other people is important as the “brain seems to be rather like a muscle—the more you use it, the stronger it gets”. However, the opposite is also true—so people who share a home or workplace with the intellectually challenged risk seeing their IQ levels nosedive as a result.

Professor Flynn analyzed US intelligence tests from the last 65 years and created new IQ “age tables”. He found a bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage compared to a similar child with equally bright brothers and sisters. However, children with a low IQ could gain six to eight points by having brighter brothers and sisters and special educational treatment to help pull them up.

Professor Flynn concluded that although genetics and early life experiences determine about 80% of intelligence, the remaining 20% is linked to lifestyle. This means people can raise their IQ, or allow it to fall, by ten points or more. He suggests the best way to improve IQ levels is to socialize with bright friends, and find an intellectually challenging job.

1.What do people commonly believe?

A.People1 s IQ levels fall as they get older and older.

B.It’s wise for people to share family members’ views.

C.The intelligence changes no more during adulthood.

D.Doing challenging deeds is good for one’s intelligence.

2.The underlined word “nosedive” in Paragraph 2 most probably means ________.

A.vary B.fall C.change D.develop

3.Which of the following can help improve one’s intelligence according to Professor Flynn?

A.Staying with smart people. B.Making many friends.

C.Doing exercise every day. D.Learning from parents.

4.The purpose of the text is to ________.

A.persuade B.advertise C.entertain D.inform

The next time your brain refuses to recall a simple fact or name, be thankful. That could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions.

The researchers say there are numerous neurobiological(神经生物学的)studies conducted on how the brain stores information, a process called persistence (暂留). However, scientists also assumed that our occasional inability to recall facts was due to a are an the brain. In 2013, scientists discovered that as new neurons combine with the hippocampus(海马区)----a region of the brain that plays a significant role in learning and remembering---they overwrite old memories, making them harder to access. There is also evidence that the brain weakens or removes connections between neurons, in which memories are encoded.

The scientists have a theory on why the brain spends so much energy erasing memories. They say what the brain decides to forget is determined by our daily life. An example is that our brains remember phone numbers according to the need. Instead of storing this irrelevant information that our phones can store for us, our brains are freed up to store the memories that actually do matter for us. They also believe that memorizing too much detail could prevent us from making good decisions.

So the next time you are unable to recall a seemingly important fact, don’t be hard on yourself. Just throw it to your brain’s “rubbish can” to make room for information that can contribute to making you smarter! Remember, even Albert Einstein was absent-minded!

1.What can we know from the first two paragraphs?

A. Persistence is not a process to store information

B. Once information is stored in the brain, it will last forever

C. Learning and memorizing take place in the hippocampus

D. New neurons will strengthen old memories

2.The brain has to erase memories to __________.

A. recall important information

B. store more important information

C. store detail

D. remember phone numbers

3.If some unimportant information is stored, it will be _________.

A. combined with the hippocampus

B. processed and memorized permanently

C. stored and decoded immediately

D. removed and forgotten soon

4.What is the best title of the passage?

A. Scientists encourage us to forget things

B. The way our brains memorize and encode

C. Forgetting things may make you smarter

D. Why was Albert Einstein absent-minded?
