1 . We often hear friends ask why they should read fiction. There is so much to learn from history, from what is going on at the frontiers of science, and from contemporary studies of human behavior. Why should they spend their scarce "free time" reading fiction, the purpose of which, at best, is only entertainment?
We are disappointed about such comments. Yes, we respond, we do find pleasure in reading fiction. But we also learn much about how to best live our lives in ways that can only be captured by fiction. We recognize that some novels are entertaining, but leave no lasting impression. What makes a novel more than entertainment?
Our answer is that we don't just read great books - they read us as well. The human condition is complex and contradictory, layered like an ice-cream dessert, with flavors mixed among the layers. A great novel reflects that complexity. We may read it several times, as we do with our favorites, and each time it is like finding an old friend and gaining new insights from that friend. We put it down with new understandings of the world around us and, most important, of ourselves.
Let's look at the novel Frankenstein, written in 1818 by Mary Shelley. Frankenstein is not the monster, but a young man seeking out the secrets of the universe. He collects body parts and charges it with life. When the dull yellow eyes open, however, Frankenstein, shocked by what he has done, abandons the creature, which ultimately kills Frankenstein's brother, his bride, and his best friend.
On one level, Frankenstein is entertaining - a good horror story, though a little dated. But Shelley writes more than just that. On a deeper level, her book forces us to ask whether humans reach too far to gain knowledge that is as forbidden as the fruit of the Garden of Eden. This theme, as old as the legend of Prometheus （普罗米修斯），dominates Frankenstein. Shelley, of course, knew nothing of genetic （遗传的）engineering that happens today. She was deeply troubled by what human beings might discover about themselves, and the effects of those discoveries on society. Our reading of great literature can also be enriched by understanding the author's personal interests and anxieties.

2 . Windows are a key component in a building's design, but they are also the least energy- efficient part. According to a 2009 report by the United Nations, buildings account for 40 percent of global energy usage, and windows are responsible for half of that energy consumption. If conventional windows are used to better block sunlight passing into a building, they need expensive coatings. Even so, they can not adjust the indoor temperature effectively.
Scientists at the Nanyang Technological University, Singapore (NTU) have developed a smart liquid window panel that can help. By creating a mixture of micro-hydrogel (水凝胶), water, and a stabilizer, they found that it can effectively reduce energy consumption in a variety of climates. Thanks to the hydrogel, the mixture becomes hard-to-see- through when exposed to heat, thus blocking sunlight, and, when cool, it returns to its original clear state. The high heat capacity of water allows a large amount of heat energy to be stored instead of getting transferred through the glass and into the building during the hot daytime when office buildings mainly operate. The heat will then be gradually cooled and released at night when the staff are off duty.
As a proof of concept, the scientists conducted outdoor tests in hot (Singapore, Guangzhou) and cold (Beijing) environments. The Singapore test revealed that the smart liquid window had a lower temperature (50°C) during the hottest time of the day (noon) compared to a normal glass window (84°C), The Beijing tests showed that the room using the smart liquid window consumed 11 percent less energy to maintain the same temperature compared to the room with a normal glass window. They also measured when the highest value of stored heat energy of the day occurred. This "temperature peak" in the normal glass window was 2 pm, and in the smart liquid window was shifted to 3 pm. If this temperature peak shift leads to a shift in the time when a building needs to draw on electrical power to cool or warm the building, it should result in lower energy charges for users. The research team is seeking ways to cut down the cost of producing the smart window and so far, they have found several industry partners to commercialize it.

3 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.
1. How did Ben “see” after he had his eyes removed?| A．By using a walking stick. | B．By asking others for help. |
| C．By inventing a new system. | D．By echolocating surroundings. |
| A．Skill. | B．Task. | C．Sense. | D．Invention. |
| A．He laughs best who laughs last. | B．Actions speak louder than words. |
| C．God shuts one door but he opens another. | D．Man becomes learned by asking questions. |
| A．Culture Shock. | B．Human Biology. |
| C．Scientific Technology. | D．Environmental Protection. |
