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.

4 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

One day, when I was a first-year student in high school, I saw a kid from my class walking home from school. His name was Kris. It looked like he was carrying all of his books. I thought to myself, “Why would anyone bring home all his books on a Friday? He must really be a nerd (书呆子).”

I had quite a weekend planned (parties and a football game with my friends), so I shrugged my shoulders and went on. As I was walking, I saw a gang of kids running toward him. They ran at him, knocking all his books out of arms and tripping him so he landed in the dirt. His glasses went flying, and I saw them land in the grass about ten feet from him. He looked up, and I saw terrible sadness in his eyes.

My heart went out to him. So I jogged over to him, and as he crawled around looking for his glasses, I saw tears in his eyes. As I handed him his glasses, I said, “They are bad guys! They really should be punished.” He looked at me and said, “Hey, thanks!” There was a big smile on his face. It was one of those smiles that showed real gratitude.

I helped him pick up his books and asked him where he lived. As it turned out, he lived near me, so I asked him why I had never seen him before. He said he had gone to a private school before. I would have never hung out with a private school kid before, but we talked all the way home, and I carried his books.

注意：
