問題詳情：

Beijing is hardly alone in its air pollution problems. The world Health Organization has said that roughly half of the world’s urban population is exposed to pollution at least 2.5 times higher than it recommends.

While it may take years to fix this global problem, innovative minds in the Asia region have come up with creative solutions for living with air pollution.

DIY Purifier

Thomas Talhelm started worrying about the air inside his Beijing home during “airpocalypse”(空氣末日) in 2013 when Beijing’s air quality index skyrocketed to a terrifying 755.

The scholar couldn’t afford the luxury of an expensive air purifier. “Filters (過濾器) are actually very simple—a high efficient filter is all you need to get over 96% of the PM2.5,” he said.

With three of his friends, Talhelm created Smart Air, an air purifier consisting of a basic household fan with a high efficient filter attached to it.

It works as efficiently as the big brands selling for thousands of dollars, removing more than 90 percent of PM2.5 in your room, according to Talhelm’s research.

Invisible Mask

Infipure’s “nose mask” claims to cut 99% of PM2.5 without the trouble of a surgical face mask.

The filters, made from special materials, are inserted into your nose and aim to be undetectable.

“People care about their health, but don’t want all the downsides that come with a traditional face mask,” Infipure co-founder Francis Law explained.

Plant Backpack

Taiwanese artist Chui Chih has designed a survival device for an apocalyptic world.

Named Voyage on the Planet, a potted plant is housed inside a clear backpack hooked up to two tubes to bring fresh air to a face mask. It’s a bold, abstract idea from an oxygen tank.

Smog Vacuum

Daan Roosegaarde has been working on a smog vacuum that will suck pollutants from the sky to the ground like a vacuum, making way for clean air.

A byproduct of this smog vacuum, namely The Smog Free Tower, is the “smog ring”—a piece of jewelry made from smog particulates(微粒).

“The pollution we suck up, the small particulates, we don’t throw them away. We put them under pressure for a couple of weeks and they crystallize, creating something like a diamond,” Roosegaarde explains.

70. Thomas Talhelm invented Smart Air for all the following reasons except _______.

A. the high price of the big brands

B. the help from three of his friends

C. the poor quality of the indoor air

D. the simple principle behind the device

71. If someone wants to travel around in those polluted days, which product will he most probably choose for the sake of convenience?

A. Smart Air. B. Infipure’s nose mask.

C. Voyage on the Planet. D. The Smog Free Tower.

72. In which solution the inventor also makes use of the dust collected from the polluted air?

A. DIY Purifier. B. Invisible Mask.

C. Plant Backpack. D. Smog Vacuum.
