1 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.

The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.

“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.

Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

2 . People generally like to pick out the best-looking fruits and vegetables when shopping for produce (农产品), but Canadian supermarket chain Loblaws is attracting customers with badly-shaped and faulty produce at the price of 30% lower than normal-looking one.

A trial run of the ugly food line, named “Naturally Imperfect”, began with only apples and potatoes to choose from. Consumer demand has been so huge that Loblaws is going to introduce more ugly vegetables and fruits like onions and mushrooms.

All the produce that will be sold through Naturally Imperfect would otherwise have been used in juices, sauces, or soups, or have not been harvested at all. The director Dan Branson explained that this program benefited both food producers who would otherwise have to let abnormal produce go to waste, and consumers who could buy fresh produce at low prices. And he was right, given how popular the line has become.

“It really went well beyond our expectation,” Branson said. “I think it really spoke to the fact that Canadians are out there really looking for some options.”

Of course, Canadians know that beauty is more than skin deep, and they also recognize that they can get the same flavor and nutritional benefits in spite of appearances. The positive response to the initial offering of apples and potatoes showed the opportunity to expand the line and offer more options at a greater price to Canadian families.

“If you grow produce in your backyard, there will be a lot of produce that won’t look as pretty as what you will see in a grocery store”, said Branson. “And nature doesn’t grow everything perfectly. I’d like to think if somebody were to take a No Name Naturally Imperfect apple, put it right beside a No.1 apple, close his eyes and eat them, there would be no difference.”

1. Loblaws is different from other supermarkets in that ______.

A．more fruits are offered at lower prices	B．normal-looking produce is forbidden there
C．only apples and potatoes are sold every day	D．imperfect produce is sold at lower prices there

2. According to Paragraph 3, Loblaws’s program ______.

A．prevents people from wasting their food	B．happens to be a win-win mode
C．teaches food producers how to grow	D．enables consumers to eat more fresh produce

3. What is Paragraph 5 mainly about?

A．Canadians are used to eating perfect produce.

B．Smart consumers know the importance of ugly produce.

C．Loblaws intends to improve customers’ quality of life.

D．Customers’ support promotes the development of the ugly food line.

4. What do Branson’s words in the last paragraph mainly tell us?

A．Imperfect fruits are as tasty and nutritious as perfect ones.

B．The world is usually full of imperfect things.

C．We should eat imperfect apples with our eyes closed.

D．The fruits grown by ourselves are more nutritious than those in the store.

As the saying goes, chances preferred the prepared mind. I learned this from one of my experience.

I was not chosen as member of the volleyball team of our school. Because of this, I decided to give up play volleyball. Lucky, my best friend stopped me but pointed out that it was my laziness and poor preparation which led to my failure. After that, I practiced playing the volleyball every day. When another tryout arrived, I was fully prepared and tried my best. As a result, I was selected and became an important player on our school team.

From this, I am firmly convincing that, no matter when chances arrive, we were able to seize them as long as we get well prepared.
