Green is an important color in nature. It is the color of grass and the leaves on trees. It is the color of most growing plants, too.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet finished or plants that are not ripe.
For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in war (战争). By the eighteenth century, a greenhorn had the meaning it has today--a person who is new in a job.
About one hundred years ago, greenhorn was a popular expression in the American west. Old-timers used it to describe a man who had just arrived from one of the big cities in the east. The greenhorn didn’t have the skills that he would need to live in the hard, rough country.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds.
A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution (革命) is the name which was given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural (农业的) scientists who had green thumbs.

第一节：阅读理解（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
（A）
In 2008, the main candidates（候选人）for President each used this expression: “You can put lipstick（口红）on a pig, but it is still a pig.” This means that it is a waste of time to change something from ugly or unpleasant–looking to beautiful.
There are other expressions about improving a pig’s appearance, like this one: “A hog in a silk waistcoat is still a hog.” Hogs are similar to pigs, only bigger. Americans use many other expressions about pigs, hogs and female hogs called sows, like this one, “You cannot make a silk purse out of a sow’s ear.” This means you cannot create something valuable from something that has no value. Then there is the expression “Cast pearls before swine（猪）.” That means wasting something valuable on someone who will not be thankful or care about it.
Hogs, which are very large animals, take up a lot of space but people should not take up more than their share. If one of your children is taking up too much space sitting in front of the television, other children might say: “Do not hog the couch.” And a road hog is a driver who uses more than his share of the road. Such a driver increases dangers for other drivers.
Pig terms are also used in American politics. Farmers mark their pig’s ears to identify them. In politics, earmarks are money set aside for projects in a congressman’s home state.
In many areas, pigs provide ham, bacon and other pork products to eat. All Americans want to be able to bring home the bacon because they want to earn enough money to provide the necessities of life. Experts say this term was first used in the 1920s. But it is believed to come from the much older game of catching a greased（涂了油的）pig. This was a popular event at country fairs in which the winner was awarded the pig.
41. The author writes this passage mainly to _________.
A. express his support for the Presidential Election
B. introduce some expressions used in Americans’ daily life
C. criticize the bad influence caused by expressions about pigs
D. discuss some problems caused by expressions about pigs
42. If you give a good book to a person who can’t read, which of the following is the most suitable to describe it?
A. Cast pearls before swine.
B. You can put lipstick on a pig, but it is still a pig.
C. A hog in a silk waistcoat is still a hog.
D. You cannot make a silk purse out of a sow’s ear.
43. A driver who takes up too much space on the road is often referred to as _________.
A. a greased pig B. a couch hog
C. a road hog D. a road earmark
44. How many words which refer to the same animal are mentioned in this passage?
A. Three B. Four C. Five D. Six
45. Which of the following expressions are similar to “You cannot make a silk purse out of a sow’s ear.”?
A. When pigs fly! B. To eat like a pig
C. To sell a pig in a pork. D. To sweat like a pig.
When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction.
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
1.The aim of the extinction of large prehistoric animals is to suggest that _______.
A．large animal were not easy to survive in the changing environment
B．small species survived as large animals disappeared
C．large sea animals may face the same threat today.
D．Slow-growing fish outlive fast-growing ones
2.We can infer from Dr Myers and Dr. Worm’s paper that _______.
A．the stock of large predators in some old fisheries has reduced by 90%
B．there are only half as many fisheries are there were 15 years ago
C．the catch sizes in new fisheries are only 20% of the original amount
D．the number of larger predators dropped faster in new fisheries than in the old
3.By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.
A．fishing technology has improved rapidly
B．then catch-sizes are actually smaller then recorded
C．the marine biomass has suffered a greater loss
D．the date collected so far are out of date.
4.Dr Myers and other researchers hold that _______.
A．people should look for a baseline that can’t work for a longer time
B．fisheries should keep the yield below 50% of the biomass
C．the ocean biomass should restore its original level.
D．people should adjust the fishing baseline to changing situation.
5.The author seems to be mainly concerned with most fisheries’ _______.
A．management efficiency
B．biomass level
C．catch-size limits
D．technological application.
Adults usually do not remember most of the things that are taught by their teachers at school. But this story is one such lesson that I will never forget. Every time I drift off course, I think of this story.
It was a normal Monday morning, and my teacher was teaching us on important things in life and about devoting ourselves to what is important to us. This is how the story went:
An old man lived in a certain part of London, and he would wake up every morning and go to the subway. He would get onto the train right to Central London, and then sit at the street corner and beg. He would do this every single day of his life. He sat at the same street corner and begged for almost 20 years.
His house was dirty, and a stench (恶臭) came out of the house and it smelled terrible. The neighbors could not stand the smell any more, so they called for the police officers to clear the place. The officers knocked down the door and cleaned the house. There were small bags of money all over the house that he had collected over the years.
The police counted the money, and they soon realized that the old man was a millionaire (百万富翁). They waited outside his house expecting to share the good news with him. When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a rich man now, a millionaire.
But the old man said nothing at all; he went into his house and locked the door. The next morning he woke up as usual, went to the subway, sat at the street corner and continued to beg.
Clearly, this old man had no great plans, dreams or anything significant (有意义的) for his life. We learn nothing from this story other than staying focused on the things we enjoy doing.
【小题1】The neighbor called the police because ______.
| A．the old man kept begging money from them every day |
| B．there was something dangerous in the old man’s house |
| C．the old man wouldn’t buy tickets for the train |
| D．they couldn’t bear the smell from the old man’s house |
| A．remained calm | B．became excited |
| C．felt worried | D．became nervous |
| A．Make great plans for your life. |
| B．Keep on doing what you like. |
| C．Do something that is good to society. |
| D．Depend on yourself rather than others. |
Rene Descartes’ explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon – that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes’ terms — as a physical process, a sign of tissue injury.
The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes’ model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord(脊髓). In some cases, this imaginary gate could simply stop pain signals from getting to the brain.
Their most amazing suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other “output” from the brain. They were saying that pulling on the rope need not make the bell ring. The bell itself —the mind— could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after immersing your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury.
The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male nondancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers — a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic(慢性) injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one’s sensitivity to pain.
There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo(安慰剂) injection and promised that it would relieve their pain had the least discomfort — not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work.
Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string. Today every medical textbook teaches the gate control theory as fact. There’s a problem with it, though. It explains people who have injuries but feel no pain, but it doesn’t explain the reverse, which is far more common — the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? The rope and clapper are gone, but the bell is still ringing.
