题干

Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.
【小题1】According to Anderson, before 1970, Americans had little idea about ___.

A．the social movement	B．recycling techniques
C．environmental problems	D．the importance of Earth Day

【小题2】Where does the support for environmental protection mainly come from?

A．The grass –roots level.	B．The business circle.
C．Government officials.	D．University professors.

【小题3】What have Americans achieved in environmental protection?

A．They have cut car emissions to the lowest.

B．They have settled their environmental problems.

C．They have lowered their CO levels in forty cities.

D．They have reduced pollution through effective measures.

【小题4】What is especially important for environmental protection according to the last paragraph?

A．Education.	B．Planning
C．Green living	D．CO reduction

The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environmentfriendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of hightech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.
Among them，there are hydroelectricpowered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.
Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panelfitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.
【小题1】The hottest “green”toy in Germany is ________.

A．made of rubbish

B．made of organic or recycled materials

C．equipped with a solar panel

D．driven by an advanced motor

【小题2】The purpose of making the green toys is to ________.

A．raise kids' awareness about energy and environment

B．improve kids' imagination

C．give kids the knowledge of technology

D．improve the safety of toys

【小题3】We can infer from the last paragraph that the green toys ________.

A．can help save little energy

B．are not accepted by parents

C．will sell well in the future

D．have not been produced

【小题4】Which of the following BEST describes the opinion of Earthsense about green toys?

A．Doubtful.	B．Optimistic.

C
The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
【小题1】What can we learn about full-sun coffee production from Paragraph 4?

A．It limits the spread of new growing techniques.

B．It leads to air pollution and global warming.

C．It slows down the loss of shade trees.

D．It improves local soil conditions.

【小题2】The purpose of the text is to .

There was a time when a trip to the supermarket in the United States often ended with a seemingly simple question from the cashier, "Paper or plastic？"Well, which type of bag would you choose？

While both types of bags have some influence on the environment, it has long been supposed that paper bags are kinder. They are made from a renewable source, are broken down easily, burn without giving off thick smoke and can be recycled. However, the producing process behind paper bags uses more energy than that of plastic ones. How can this be true？

Studies show that paper bag production requires four times as much energy as plastic bag production.

And the amount of water used to make them is twenty times higher. Besides, the influence on forests is very serious. It takes about fourteen million trees to produce ten billion paper bags, which happen to be the number of bags used in the United States yearly. In terms of recycling, the idea that paper bags are more environment friendly than plastic ones can be quickly discarded. Research shows it requires about 98% less energy to recycle plastic than it does to recycle paper.

Even though paper bags might be more harmful than plastic ones, plastic still seems to be considered as the more harmful of the two by governments. In Ireland, for example, a tax has been introduced to discourage the use of plastic bags. People have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.

There’s no doubt that it makes more sense to reuse these bags. However, we don’t seem to be doing that at present. That may be because they fall apart quickly. If so, cloth bags are a better choice, but still, their production also has a bad influence on the environment. So what to do? How should we answer the question of “Paper or plastic?” It seems that we first need to ask ourselves one more general question: “What can I do to help the environment?”

【小题1】The question at the end of Paragraph 1 is used to ________.

A．introduce points for discussion

B．tell readers how to save money

C．express the author's doubts

D．show the kindness of the cashier

【小题2】Compared with plastic bags, paper bags ________.

A．take more time to break down

B．require less energy to recycle

C．need more water to produce

D．have less influence on forests

【小题3】The underlined word “discarded” in Paragraph 3 probably means "________".
