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 o
f 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 (电梯) 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.
M
ore 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.小题1:________ 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-measurin g sensors that control lights |
| D．Window coating that lets light in, but keeps heat out |
A．se nd people to floors with fewer stops | B．teach people how to use their ID cards |
| C．make people stay very cool in summer | D．help people go traveling in the building |

e, I heard the phone ringing. It was my friend Lydia, upset over an argument with her husband. My usual approach is to offer advice, but this time, extremely tired from chores, I simply pulled off my coat, sat down in a chair and listened to my friend"s f
rustration and sadness. Without the disturbance of judgment or the desire to comfort her, I stayed totally quiet while she talked. Eventually Lydia"s depression eased and we said our goodbyes. The next day she phoned to thank me. "I"m so grateful for the way you helped me through this," she said.At first I was surprised. After all, I had done nothing except be there for her. But after I had my own venting(发泄的) experience with another friend later that evening, I realized that my focused silence had some value. In fact, most relationship experts agree that talk is cheap; it"s listening that"s rare and valuable. It allows you not only to hear what the other person is saying, but also to have a clear understanding of her thoughts and feelings. And for the speaker, that level of understanding translates into concern and respect.
Unfortunately, listening isn"t as easy as it sounds. Thanks to schedules filled with family and work, multitasking has become the barrier(障碍) to listening. My tiredness may have been the only thing stopping me from folding laundry or checking my e-mail while Lydia talked that afternoon.
Another barrier to listening is our listening system: Most of us take in only about half of what"s being said during a conversation, according to the International Listening Association. Research shows that we speak at 125 to 150 words per minute, yet think at 500 words a minute. Therefore, because we think much more quickly than we speak, it is easy for us to lose our concentration when listening to speakers.
While it can be hard to focus at times, it"s a skill worth developing. With a little practice — employing some techniques— you can become a better listener.

| C．her own listening experience | D．her own venting experience |
| A．we think much more quickly than we speak |
| B．we can only understand about half of what we hear |
| C．there is not much thinking time available while we are listening |
D．we lose our concentration easily while we are listen ing |
| A．Why listening is valuable. | B．What we should do while listening |

A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. Whom the gods would destroy they first make mad. Keep cool, says George Herbert, for fierceness (狂怒) makes error a fault.
To be angry with a weak man is to prove that you are not strong yourself. Anger, says Pythagoras, brings with folly(愚蠢)and ends with regret. You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.

Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
小题1: Which of the following is true according to the passage？
| A．Genetic limitation will be beneficial for some women |
| B．A large number of genes will prevent us from developing |
| C．Prohibition(禁止) of cloning might limit the freedom of scientists |
| D．First cloned humans might be normal according to scientists |
| A．Cloning should be entirely banned |
| B．Cloning should be used in creating life |
| C．Cloning will take away the right to reproduce |
| D．Cloning is acceptable if it is used for cloning organs |
Scientists have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes you have.
For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern (组合).
The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.
The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.
Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.
The studies show that tiny mutations (变异) in the make-up of some genes can greatly increase a person’s lifespan (寿命). Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.
David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.
“If we know which genes control longevity (长寿) then we can … target them with drugs. That makes it possible to slow down ageing,” he told The Times.
“Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged (义不容辞的) to take it.”
小题1:According to the article, which of the following is the most important if a person is to live to the age of 100?
| A．Eating healthy food every day. | B．Having the right types of genes. |
| C．Having a healthy lifestyle. | D．Taking drugs that prevent ageing. |
| A．10% | B．20% | C．30% | D．50% |
| A．The team studied the genes of over 100 people over 100 years of age. |
| B．The researchers found that mutations in certain genes lead to longer life. |
| C．The researchers found ways to develop drugs that could cure age-related diseases. |
| D．The study suggested that most people have genes that could lengthen their lives. |
| A．drugs to slow ageing will be very expensive |
| B．modern science will be able to find more longevity genes |
| C．it is the duty of medical scientists to fight the problems of ageing |
| D．scientists can make new genes that will allow longer life |
