At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it’s sunny and brighten when a passing cloud blocks the sun.
A wall of windows at a University of Pennsylvania engineering building has built-in blinds (百叶窗) controlled by a computer program that follows the sun’s path. Buildings are getting smarter and the next generation of building materials is expected to do even more.
Windows could catch the sun’s energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up.
Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like “green roofs”, where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out.
As technologies such as sensors become cheaper, their uses spread.
The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping (刷) ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light.
More new building materials and technology are in development. A Philadelphia building firm is now working on “smart wrap” that uses tiny solar collectors to catch the sun’s energy and transmitters (传输器) as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so.________ will be developed and used in the construction industry.
A.“Green roofs” that cool or heat buildings |
B.“Smart wrap” that catches the sun’s energy |
C.Sunlight-measuring sensors that control lights |

The elevators at Seven World Trade Center are special because they can ________.
A.send people to floors with fewer stops |
B.teach people how to use their ID cards |

When I was quite young, I discovered that somewhere inside the telephone lived an amazing person - "Information Please" and there was nothing she did not know.
One day while my mother was out, I hit my finger with a hammer. The pain was terrible, but there was no one home to give me any sympathy. I walked around the house, finally arriving at the telephone! Quickly, I called “Information Please" and told her what happened.She told me to open the icebox and hold a little piece of ice to my finger.
After that, I called "Information Please" for everything. When my pet bird died, I told
"Information Please" the sad story. She tried to comfort me, she said quietly, "Paul, always remember that there are other worlds to sing in." Somehow I felt better.Another day I was on the telephone, “How do you spell ‘grateful’? ". All this took place in a small town in the Pacific Northwest. When I was 9, we moved to Boston.
A few years later, on my way to college, my plane put down in Seattle. I had about half an
hour or so between planes. Without thinking, I dialed my hometown operator and said, "Information, please."
Surprisingly, I heard the small, clear voice I knew so well, "Information." I hadn't planned on
this but I heard myself saying, "Could you please tell me how to spell ‘grateful’?"
There was a long pause. Then came the soft-spoken answer, "I guess your finger must have
healed by now."I laughed. "So it's really still you," I said, "I wonder if you have any idea how much you meant to me during that time."I told her how often I had thought of her over the years and asked if I could call her again. "Please do," she said, "Just ask for Sally."
Three months later I was back in Seattle. A different voice answered me. I was told that Sally
passed away five weeks before.
Before I could hang up she told me that Sally left a message for me—“Tell him I still say
there are other worlds to sing in. He'll know what I mean.”I thanked her and hung up. I knew what Sally meant.
Never underestimate the impression you may make on others. Whose life have you touched
today?

We would probably all be amazed if we watched a videotape of ourselves performing basically unconscious acts as we go about the business of the day. These unconscious acts consist of all the little personal habits that we don’t even think about, but definitely should. These are some of the things that present an image of who we are to others, and if we are careless in performing them, this image may well be other than we would like it to be.
Parents who insist that their children practice good manners and habits at home are doing them a great service, for these habits then become lifelong and the natural way they do things. It proves true that their unconscious actions will reflect a well-mannered person.
People who, for example, eat with both arms on the table at home will likely do so when out. Those who are lazy and slow in private will certainly be so in public. Children who are permitted to be disrespectful to their parents will follow suit with other adults, and will, most likely, become adults who are disrespectful of others. This is an area where the saying “practice makes perfect” may be applied.
There is an article about the actress, Audrey Hepburn, known for her beautiful carriage and posture. According to her biographer, her grandmother tied her neck to the back of her chair, at table, so that she would not drop down suddenly over her food, but rather would learn to put only small amounts of food on her spoon or fork and bring them to her mouth. This is a rather extreme “at home” method for the development of erect (直立的) posture, but it does illustrate the effectiveness of practicing good habits so that, when in public, they are instinctive.
Which of the following expresses the main idea of the passage?
A.Parents should be responsible for their children’s good habits. |
B.The actress is well known for her beautiful posture. |
C.We should always be aware of our manners. |
D.Without good manners, one can never be perfect. |
Those who eat with both arms on the table at home ______.
A.will probably have the same habit when they have meals in the restaurant |
B.will probably change the habit when eating out with their relatives |
C.will feel embarrassed when having meals with so many strangers in public |
D.will always put their arms on the table no matter where they eat |
The meaning of “practice makes perfect” in the third paragraph is ______.
A.the more practice one has, the better job he will do |
B.the more perfect one is, the more practice he needs |
C.if one has enough practice, he will become perfect |
D.perfect makes a person practice more |
Which of the following are NOT true?
A.If we are not careful about our unconscious acts, the images of ourselves presen![]() |
B.The good habits formed in one’s childhood will benefit him throughout his life. |
C.If parents do not care about the disrespectful attitude adopted by their children towards themselves, their children might be disrespectful of others. |
D.It is unlikely that a well-mannered person will not embarrass himself in public. |

Some years ago, a Miami woman walking through an office building noticed two men standing together.Several minutes after her leaving, the men murdered a person working in the building.The police determined that the woman was the only witness and could possibly describe them.However, her memory of the men proved disappointingly unclear.Several days later, psychologist Ronald Fisher was brought in to obtain a more complete account from the woman.His interview produced a breakthrough—the woman reported a clear picture of one of the suspects.The important information enabled the police to arrest the suspect and close the case.
The police asked Fisher for help because of his rich knowledge i
n cognitive (认知) interview, a kind of memory-rebuilding process.Memory researchers have found that people trying to remember a past event often only recall part of the relevant information.Human memory is selective and it is often distorted by stress.But a person's accurate recall of an event or understanding of a question can be improved using specific interviewing techniques.The "cognitive interview" was developed in the late 1990s.It encourages the witness to take an active role in recalling information rather than giving answers only to someone else's questions.The witness first describes what happened in his or her own words, with no interviewer interruptions.The interviewer then goes further with specific techniques, such as having the witness tell the details of what happened from different perspectives(角度).
The cognitive interview focuses on guiding witnesses through four general recalling techniques: thinking about physical surroundings and personal feelings that existed at the time of past events; reporting everything that comes to mind about those events, no matter how broken it is retelling events in a variety of time orders, such as from beginning to end, end to beginning, forward or backward; and adopting different perspectives while recalling events.
Experiments with police detectives trained in this demanding interview method find that they obtain nearly 50% more information from witnesses than before training, while error rates remain about the same.It is proved that cognitive interviews are quite important tools in improving the accuracy and completeness of witness testimony (证词).
The purpose of the passage is to _____.
A.give an account of a murder case |
B.introduce an idea of cognitive interview |
C.prove Fisher was an expert in cognitive int![]() |
D.help a witne![]() |
What is required to recall in a cognitive interview for a witness?
A.The exact time at which a murder took place. |
B.The information about the event in the time order. |
C.The important things that come to his or her mind. |
D.The surroundings and feelings at the time of the event. |
The key point in a cognitive interview is that
A.the witness is encouraged to take part in recalling information |
B.the interviewer should interrupt the witness from time to time |
C.the interview should take place outside the police station |
D.the witness should recall details at the scene of the event |
The underlined word "distorted" in the passage probably means " ____

Dr. Sylvia Earle wants you to stop eating fish. It’s not because fish are endangered, though wild fish stocks in many oceans are very low. It’s not because they’re bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they’re smart.
“Fish are sensitive, they have personalities,” says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. “I would never eat anyone I know personally.”
There’s a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see the
se as strong arguments against eating fish altogether.
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. “While it may seem obvious that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables,” says Dr. Lynne Sneddon. “Really, it’s kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?”
Fishermen and (fried) fish lovers are doubtful. “I’ve never seen a smart fish,” says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. “If they were very smart, they wouldn’t get caught.”
“For years, everyone’s been telling us to eat fish because it’s so good for us,” says another diner. “Now I’ve got to feel guilty while I’m eating my fish? What are they going to think of next? Don’t eat salad because cucumbers have feelings?”
Dr. Sylvia Earle discourage people from eating fish because _____________.
A.there are not that many wild fish in the ocean |
B.fish actually are sensitive and have personalities |
C.some ocean fish contain poisonous substances |
D.fish are like dogs or cats that people know personally |
We can infer from the passage that _____________.
A.all people don’t agree with the idea to stop eating fish |
B.people will be persuaded not to eat fish in the future |
C.stopping eating fish will lead to people’s not eating vegetables |
D.we shouldn’t care too much about the feeling of fish |
By saying “There’s a lot more to fish than meets the eye,” the writer means ______.
A.there are far more fish than other animals in the world |
B.there are more fish in the world than people can see |
C.people can see more fish if they pay more attention |
D.fish are not that simple as they appear to people’s eyes |
What is the writer’s attitude towards people eating fish?
A.Neutral. | B.Indifferent. | C.Approving. | D.Opposed. |
