To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier, it constructs a wider-meshed (网孔、网眼)web using fewer strands(线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactivity, labeled materials, it was found that 95 percent of web protein reappears in the next day web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate(无脊推动物). If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another.

解析试题分析:文章大意:讲述蜘蛛和网之间的关系。
【小题1】B主旨大意题:根据句首第一句:To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: theirmeans of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. 对许多织网的蜘蛛来说,他们大部分几乎是瞎子,网是他们在世界上必须的东西:他们交流,捕捉猎物,会见同伴,自我保护的的方式。
【小题2】C 细节理解:根据A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. 一个没有网的蜘蛛就像一个被扔在荒石岛上的人,完全与人失去联系,注定要饿死。所以选C。没有网的话,蜘蛛很可能会死掉。
【小题3】D 词义猜测:根据前文For 16 days the starving spider builds completely normal webs. 饥饿的蜘蛛16天的时间会织造完整的正常的蛛网。和后句Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. 这样的网只用来捕捉提醒大些的猎物,这样做,从一只饥饿的蜘蛛的角度来说更加合算。所以推测出更瘦的,骨瘦如柴的。
【小题4】A 细节理解根据Scientists are impressed by the adaptability of the spider's highly preprogrammed brain,蜘蛛的高度预编好的大脑的适应性给科学家们留下了深刻印象。下面用蜘蛛能修补好蜘蛛网为例证明这个论点。反之,蜘蛛能修补好蜘蛛网证明了蜘蛛有高度预编的大脑的论点。

Are morning people born or made? In my case it was definitely made. In my early 20s, I hardly went to bed before midnight, and I would always get up late the next morning.
But after a while I couldn’t ignore the high relationship between success and rising early. On those rare occasions where I did get up early, I noticed that my productivity (效率) was always higher. So I set out to become a habitual early riser. But whenever my alarm went off, my first thought was always to stop that noise and go back to sleep. Eventually some sleep research showed that my strategy was wrong.
The most common wrong strategy is this: supposing you’re going to get up earlier, you’d better go to bed earlier. It sounds very reasonable, but will usually fail.
There are two main schools (流派) of thought on sleep patterns. One is that you should go to bed and get up at the same time every day. The second school says you should go to bed when you’re tired and get up when you naturally wake up. However, I have found both are wrong if you care about productivity. If you sleep at fixed hours, you’ll sometimes go to bed when you aren’t sleepy enough. You’re wasting time lying in bed awake.
My solution is to combine both methods. I go to bed when I’m sleepy and get up with an alarm clock at a fixed time. So I always get up at the same time (in my case 5 a.m.), but I go to bed at different times every night.
However, going to bed only when I’m sleepy, and getting up at a fixed time every morning are my ways. If you want to become an early riser, you can try your own.
【小题1】According to the passage, the underlined phrase refers to ________.
A.people who stay up until the next morning |
B.people who get up early in the morning |
C.people who feel sleepy in the morning |
D.people whose productivity is the lowest in the morning |
A.Because he / she wanted to have more sleep time. |
B.Because he / she wanted to do morning exercise. |
C.Because he / she wanted to test which school is better. |
D.Because he / she found that the productivity was higher. |
A.going to bed after midnight |
B.asking scholars for advice on sleeping habits |
C.getting up early occasionally |
D.pressing off the alarm to go on sleeping |
A.Going to bed early and getting up early. |
B.Going to bed late and getting up late. |
C.Going to bed when sleepy and getting up at a fixed early time. |
D.Going to bed early and getting up late. |
A.main schools of thought on sleep patterns |
B.how to have a good sleep |
C.wrong strategies for getting up early |

We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.
【小题1】What has the new study of more than 260,000 people found?
A.Sugary sodas aren’t good for the physical health of old people. |
B.Americans have a special tooth for sweet foods. |
C.Sweetened soft-drinks may increase the risk of depression. |
D.Sweetened soft-drinks have important physical consequences. |
A.About twenty-six thousand people participated in it. |
B.The oldest participants were below 80 when the study was over. |
C.Most of the participants had depression when the study was over. |
D.The study lasted more than ten years from the beginning to the end. |
A.can reduce the harm of sweetened drinks |
B.is used to reduce the risk of depression |
C.is mainly used to make fruit punch |
D.is used to make something .sweet |
A.more research is needed to confirm the new findings |
B.the new findings aren’t consistent with any previous findings |
C.cutting one’s sodas intake will surely reduce one’s depression |
D.the new findings won’t have an impact on people’s drinking habits |

Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city.However, there’s something different about riding a London subway.It may not look different, but the historical value of one of England’s most popular forms of transportation is enough to make riding the subway a must when visiting London.With a little under 300 different stations, the subway can take you almost anywhere you need to go.
Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other.In fact, eye contact is avoided at all times.That’s not rudeness ―people are just too busy to bother looking.
Busy doing what, you ask? Well, they’re certainly not using the time for a moment of quiet thinking.Nor are they reading a book.New technology has replaced quiet habits.Today the only acceptable form of book on the London underground is an e-book.
Apple must earn a fortune from London commuters(使用月票上下班者).Since the launch of the iPhone in 2007, over 40,000―yes, that’s 40,000 “apps” have been designed.
Commuters love them because they are the perfect time-fillers.One “app”, called iShoot, is a game that features tanks.Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination.iSteam clouds the iPhone screen when you breathe into the microphone.You can then write in the “steam” on your phone screen.
For those without an iPhone, another Apple product, the iPod, may be the distraction(消遣)of choice.It’s not just teenagers who “plug in” to their music-iPods are a popular way to pass the time for all ages.
And if games, e-books and music aren’t enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work.With all these distractions, it’s amazing that people still remember to get off the train.
【小题1】Those who want to save time to reach where they go can download ______ to their iPhones.
A.iShoot | B.Tube Exits | C.iSteam | D.iPod |
A.they are going to work and have no time to communicate with each other |
B.they love reading books and do not want to be disturbed |
C.they feel sleepy because of getting up early |
D.they are busy playing games, reading e-books, listening to music or watching films |
A.computers | B.programs downloaded for the iPhone |
C.computer companies | D.fortune from London commuters |
A.for | B.against | C.neutral | D.hateful |
A.London commuters are unfriendly to strangers |
B.Apple has earned a lot of money from selling 40,000 apps |
C.technology is changing how London commuters spend their traveling time |
D.riding a London subway is a must when visiting London |

Our senses aren't just delivering a strict view of what’s going on in the world; they're affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten.
Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Rémi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens.
Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten.
For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they’d seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the disposal of our motives and needs. "Radel says.
【小题1】Why was there a delay on the day of the experiment?
A.Because hungry people needed time to fill their stomach. |
B.Because Radel wanted to create two groups of testers, hungry and non-hungry. |
C.Because noon was not the right time for any experiment. |
D.Because Radel needed time to select participants in terms of body mass index. |
A.Human’s senses aren’t just delivering a strict view of what’s going on in the world. |
B.What’s perceived by our senses affects our way of thinking. |
C.Human brains can really be at the disposal of our motives and needs. |
D.Thinking processes guarantee the normal functions of our senses. |
A.42 participants are too small a number for a serious investigation. |
B.An experiment with hungry and non-hungry participants is not reliable. |
C.Our thinking processes are independent of our senses. |
D.Humans can perceive what they need without involving high-level thinking processes |

Astronomers (天文学家) say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe.
A top NASA official and other leading scientists say that within four or five years they should discover the first Earth-like planet where life could develop, or may have already. A planet close to the size of Earth could even be found sometime this year.
At the annual American Astronomical Society conference this week, each discovery involving so-called “exoplanets” —those outside our solar system — pointed to the same conclusion:Quiet planets like Earth where life could develop probably are plentiful.
NASA’s Dew Kepler telescope and a lot of new research from the suddenly hot and competitive exoplanet field caused noticeable buzz at the meeting.Scientists are talking about being at “an incredible special place in history” and closer to answering the question. “Are we alone? For the first time, there’s an optimism that sometime in our lifetimes we’re going to get to the bottom of that,” said Simon Worden,an astronomer who heads NASA’s Ames Research Center. “If I were a betting man, which I am, I would bet we’re not alone.”
“These are big questions that reflect upon the meaning of the human race in the universe,” the director of the Vatican Observatory, the Rev. Jose Funes, said Wednesday in an interview at this week’s conference.
Worden told The Associated Press: “I would certainly expect in the next four or five years we’d have an Earth-sized planet in the habitable (可居住的) zone.”

Ever since man began to use the telephone, there have been new problems arising from the carrying of messages. At first, each message was carried by a pair of overhead wires. As a result, telephone exchanges were soon surrounded by thousands of wires. The wires were then replaced by cables (电缆),each containing many pairs of wires. Each cable is capable of carrying many messages. These cables, laid underground, replaced the overhead wires.
The more extensive telephone services have become, the more demand for these services has increased, particularly the demand for long-distance services. In China, for example, this growth is now over 30% every year. Long-distance telephone exchanges are usually in crowded cities, where is not easy to lay new labels for expanding services.
The use of radio to send telephone message and to link all telephone exchanges makes it possible to get rid of overhead wires and some underground cables.
Now man has invented the microwave system ( 微波系统 ). In a microwave system messages from various places can be brought together, and then they are sent out and received by radio. After that, the messages are split into their original form. Finally, they are sent to the places where they are going to be sent.
【小题1】The word “message” ( in paragraph 1) is close in meaning to “______”.
A.electricity | B.industry | C.information | D.wave |
A.is made of wood |
B.needs more exchange |
C.carries more messages |
D.is much longer |
A.growing | B.using | C.holding | D.understanding |

Going green seems to be fad(时尚)for a lot of people these days. Whether that is good or bad, we can’t really say, but for the tow of us, going green is not a fad but a lifestyle.
On April22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.
With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的)stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.
