Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
【小題1】What does the underlined phrase "over-consumption" refer to?

A.means burning packaging for energy |
B.helps control the greenhouse effect |
C.is the solution to gas shortage |
D.leads to a waste of land |
A.Unpackaged products are of bad quality. |
B.Supermarkets care more about packaging. |
C.Other products are better packaged than food. |

Europe is now the biggest market for organic food in the world, having grown by 25 percent a year over the past 10 years. Denmark’s agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 60 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.
So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides(殺蟲劑). Organic farmers rely on many methods — such as crop rotation (農(nóng)作物的輪作) and the use of resistant(有抵抗力的)varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.
Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture stated that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.
【小題1】The first paragraph mainly tells us _________.
A.organic farming has been performed only in Europe over the past 10 years. |
B.governments of European countries have cared less about organic farming. |
C.organic farming isn’t so popular as expected. |
D.European countries need organic food more than the other countries in the world. |
A.a(chǎn)rgue for | B.care for |
C.make up for | D.pay for |
A.It refers to farming with natural materials, instead of chemical fertilizers. |
B.It refers to farming with chemical fertilizers rather than natural fertilizers. |
C.It refers to farming with soil rather than any other thing. |
D.It refers to growing crops with man-made fertilizers and pesticides. |
A.organic farming is safer than traditional farming for the environment. |
B.the idea that organic farming is safer has not been proven by science. |
C.organic farming is accepted by the UK’s House of Commons committee. |
D.organic farming is preferred to traditional farming. |
A.The UK’s agriculture minister is an organic farmer. |
B.Organic farming is popular with young people. |
C.Farmers try every means to improve the organic sales system. |
D.Ninety-three percent of British shoppers don’t buy organic products. |

Think about the different ways that people use wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills (風(fēng)車) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏僻的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means high costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.
【小題1】From the text we know that windmills _______.
A.were invented by Europeans armies |
B.have a history of more than 2800 years |
C.used to supply power to electric lights in remote areas |
D.have rarely been used since electricity was discovered |
A.Sailing a boat. | B.Producing electricity. |
C.Grinding wheat into flour. | D.Pumping water from underground. |
A.wind power is cleaner |
B.it is one of the oldest power sources |
C.it was cheaper to create energy from wind |
D.the supply of coal and gas failed to meet ends |
A.The advantages of wind power. |
B.The design of wind power plants. |
C.The worldwide movement to save energy. |
D.The global trend (趨勢(shì)) towards producing power from wind. |

“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas A&M University. “It’s a stupid endeavor.”
That’s an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat.
They just might succeed in cloning Missy soon — or perhaps not for another five years.
Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate(代孕的)mother. The wastage of eggs and the many spontaneously aborted(流產(chǎn),發(fā)育不全) fetuses(胎)may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1996, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype(原型;雛形)is, by all accounts, athletic, good-natured and super-smart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament(氣質(zhì)、性情). In a statement of purpose, Missy's owner and the A&M team say they are “both looking forward to studying the ways that her clones differ from Missy.”
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,” Westhusin asks, “when we're not even close to getting it worked out in animals yet?”
【小題1】By “stupid endeavor”, Westhusin means to say that ________.
A.human cloning is a foolish undertaking |
B.a(chǎn)nimal cloning is absolutely impractical |
C.human cloning should be done selectively |
D.a(chǎn)nimal cloning is not worth the effort at all |
A.Its success is already in sight. |
B.It is progressing smoothly. |
C.It is doomed to utter failure. |
D.Its outcome remains uncertain. |
A.study the possibility of cloning humans |
B.search for ways to modify its temperament |
C.find out the differences between Missy and its clones |
D.examine the reproductive system of the dog species |
A.a(chǎn) bad temper |
B.defective(有缺陷的、有毛病的)organs |
C.immune deficiency |
D.a(chǎn)n abnormal shape |
A.Cloning of Missy |
B.Scientist Says ‘No’ to Human Cloning |
C.Human Cloning Is Dangerous . |

An experiment was carried out at British school into the performance of new pupils. At the start of the year, the pupils were each given a rating, ranging from “excellent prospect” to “unlikely to do well”. These were totally untrue ratings and did not reflect how well the pupils had previously performed. However, these ratings were given to the teachers. At the end of the year, the experimenters compared the pupils’ performance with the ratings. Despite their real abilities, there was an astonishingly high connection between performance and ratings. It seems that people perform as well as we expect them to.
The Self-fulfilling Effect is also known as the Pygmalion Effect. This comes from an old Greek story. The story was also the basis of George Bernard Shaw’s play “Pygmalion”, later turned into the musical “My Fair Lady”. In Shaw’s play, Professor Henry Higgins claims he can turn a Cockney flower girl, Eliza Doolittle into a duchess. But, as Eliza herself points out to Higgins’ friend Pickering, it isn’t what she learns or does that determines whether she will become a duchess, but how she’s treated.
The implication (含義) of the Pygmalion Effect for leaders and managers is massive. It means that the performance of your team depends less on them than it does on you. The performance you get from people is no more or less than what you expect, which means you must always expect the best. As Goethe said, “Treat a man as he is and he will remain as he is. Treat a man as he can and should be and he will become as he can and should be.”
【小題1】The underlined word “rating” in Paragraph 1 can be replaced by “_________”.
A.program | B.regulation |
C.correction | D.classification |
A.A new scientific experiment. |
B.The Self-fulfilling Effect. |
C.Shaw’s play “Pygmalion”. |
D.An improved teaching method. |
A.try out a new teaching method |
B.pick out the most excellent pupils |
C.learn if expectations affect performance |
D.give each pupil a proper rating |
A.Strict training from Higgins. |
B.Her own strong will and hard work. |
C.The proper way she was regarded |
D.Warm encouragement from Pickering. |
A.I’m sure you can make it |
B.I will help you any time |
C.It is as easy as pie |

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit. There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
【小題1】 Rainforests can help to adjust the climate because they________.
A.reflect more heat into the atmosphere |
B.bring about high rainfall throughout the world |
C.rarely cause the temperature to drop lower than 16℃ |
D.a(chǎn)bsorb the heat from the sun, reducing the effect of heat from the sun on the earth |
A.We will lose much more than we can gain. |
B.Humans have begun destroying rainforests. |
C.People have a strong desire for resources. |
D.Much carbon dioxide comes from burning rainforests. |
A.we can get enough resources without rainforests |
B.there is great medicine potential in rainforests |
C.we will grow fewer kinds of crops in the gained land |
D.the level of annual rainfall affects wind patterns |
A.How to Save Rainforests? |
B.How to Protect Nature? |

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鷹), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
【小題1】Why do people kill animals?
A.They kill animals for something they need. |
B.They kill animals to raise some money. |
C.Animals destroy their natural resources. |
D.Animals create many problems. |
A.they give us a source of food |
B.they are beautiful and lovely |
C.they keep the balance of nature |
D.they give us a lot of pleasure |
A.People care much about animals because they need them. |
B.Once a certain kind of animal is gone forever, there will never be any more. |
C.Killing all rats and mice may cause some new problems. |
D.People must not kill any animal or plant. |

The size and location of the world’s deserts are always changing. Over millions of years, as climates change and mountains rise, new dry and wet areas appear. But within the last hundred years deserts have been increasing after frightful speed. This is partly because of natural changes, but most responsible for creating deserts are men.
Man can make deserts, but they can also prevent them from getting bigger. Algeria is planning a green belt of trees along the edge of the Sahara Desert to stop the sand. In China, too, windbreaks are being built in the northwest to keep the desert from growing.
But desert still threaten the world. Experts believe that land that is on the way to becoming deserts equals the size of Australia, Russia and US put together. Can we stop the spread of the world’s deserts and save the land that is so essential to mankind? Yes, we can, And we must.
【小題1】The reason for the land that turns into deserts is mostly because of _______
A.the changing of the climates | B.man |
C.the natural changes | D.the wind |
A.trees planted as a belt to stop the wind |
B.high walls as a belt to stop the wind |
C.long and deep ditch as a belt to stop the wind |

Grasshoppers are having to change their song — one of the iconic sounds of summer — to make themselves heard above the noise of road traffic, ecologists have discovered. The study, published in the British Ecological Society's journal Functional Ecology, is the first to show that human-made noise affects natural insect populations. Animals use sound to communicate for many reasons, including marking out territory, warning of predators and finding mates, and although previous research shows birds, whales and even frogs change their calls in noisy environments, the impact of human-made noise on insects has been neglected until now. Ulrike Lampe and colleagues from the University of Bielefeld in Germany caught 188 male bow-winged grasshoppers, half from quiet locations and half from beside busy roads. The grasshoppers use their song to attract mates.
The team then studied the differences in the two groups' songs in the laboratory. To encourage them to sing they exposed the males to a female grasshopper, and then recorded their courtship songs. Analysis of almost 1,000 recordings revealed grasshoppers living beside noisy roads produced different songs to those living in quieter locations.
According to Lampe: "Bow-winged grasshoppers produce songs that include low and high frequency components. We found that grasshoppers from noisy habitats increase the volume of the lower-frequency part of their song, which makes sense since road noise can mask signals in this part of the frequency spectrum(頻譜)."
The team's findings are important because traffic noise could be upsetting the grasshopper's mating system(交配系統(tǒng)). "Increased noise levels could affect grasshopper courtship in several ways. It could prevent females from hearing male courtship songs properly, prevent females from recognizing males of their own species, or impair females' ability to estimate how attractive a male is from his song," Lampe explains.
Having discovered that human-made noise affects insect communication, the researchers now want to learn more about how the mechanism works, and whether the grasshoppers adapt to noise during their development as larvae(幼蟲), or whether males from noisy habitats produce different songs due to genetic differences.
The bow-winged grasshopper is a common species in Central Europe. Adults occur mainly between July and September, preferring dry grasslands. Around 1.5 cm long, they vary in colour from green and browns to red and purple. The male's song consists of 2 second-long phrases that increase in amplitude (振幅) towards the end. The beginning of a phrase is characterized by slower ticking sounds that increase in speed and amplitude, leading to a buzzing sound towards the end of the phrase. A courtship song usually includes 2 phrases.
【小題1】The author wrote the article to _________________.
A.introduce how grasshoppers make noises to attract mates. |
B.raise the awareness of protecting bow-winged grasshoppers. |
C.inform us of a recent discovery of ecological research. |
D.warn us that human-made noise has changed ecological system. |

B.Grasshoppers change their songs to adapt to the noisy environment. |
C.Grasshoppers’ songs include both low and high frequency components. |
D.Bow-winged grasshoppers are a common species in Central Europe. |
A.repair | B.develop |
C.weaken | D.improve |
A.Road noise can cover the lower-frequency part of their song. |
B.Animals make sounds only for the purpose of finding mates. |
C.Grasshopper larvae learn to adapt to human-made noise. |
