Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste.

In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away.

But instead of being buried in land, some feathers could find a future in plastics（塑料）.

One of the products they have developed is a flowerpot（花盆）. It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it breaks down, it naturally becomes nutrient（營養(yǎng)物） in the soil.

The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private（私人） organization（組織）.

Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics.

He says feathers are much stronger and last（持續(xù)） longer than another plant material. "Feathers are stronger. By design, feathers are also more durable（耐用的）. And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly."

He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used.

"Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt.

Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two.

1.What do people mainly deal with feathers?

A．Feathers are used to make pillows, coats and other products.

B．Most feathers are paid no attention to.

C．Most feathers are used as nutrient

D．Most feathers are used to make flowerpots

2.What’s the advantage of the flowerpots?

A．They won’t last long.                    B．They can’t break

C．They are environmentally friendly           D．They can be reused

3.What does Walter Schmidt think of traditional flowerpots?

A．Too heavy                             B．Too old

C．Never re-used                          D．lasting longer but unnecessary

4.What do you think is the main idea of the passage?

A．Chicken and its feathers                  B．How to deal with feathers

C．feathers made into flowerpot              D．New flowerpots

When you watch TV programs about wild animals, it is surprising to see how an antelope can escape a lion’s attack. In the wilderness, everyone has a stunt. Even plants have their own ways of fighting off enemies.

Over millions of years of evolution, plants have developed a unique defence system. Chemicals are wildly used for survival. By making their leaves, flowers, roots and fruits distasteful or poisonous(有毒的) to enemies, plants can fight back.

One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount of poison increases in the other leaves. “It’s like the damaged leaves telephoning the others telling them to fight together against the enemy, ” he said.

The tree also sends defence messages to neighboring plants by giving out a special smell. Golden Wattle trees in the surrounding 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, it will die.

Every species of plant or tree is good at the production of a particular set of chemicals. A herbivore that can safely eat the leaves of one tree may be poisoned by its neighbor.

In this way, plants have developed not only individual defence system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.

1. Which of the following can be the best title of the passage?

A．Plants Fight back with Poisons

B．Plants Can Kill Animals

C．Animals and Plants

D．Lions and Antelopes

2.According to the study, if one Golden Wattle tree is attacked by animals, it can________.

A．tell other trees to protect it

B．produce more poison within 10 minutes

C．send defence messages to the neighboring plants

D．kill the animals with its leaves

3. In this passage the underlined word “herbivore” probably means animals which ________.

A．live on both animals and plants

B．feed on smaller animals

C．live on trees

D．feed on plants or grass

4.The last paragraph of the passage suggests that this kind of defence system________.

A．does great harm to the animals

B．does good to the forests

C．is helpful to some animals

D．harms the forests

At one time, computers were expected largely to remove the need for paper copies of documents  because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.

Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers .

Does all this mean environmental concerns have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling (回收利用)?” said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.  

1. The growing demand for paper in recent years is largely due to       ____.

A. the rapid development of small businesses        B. the opening up of new markets

C. the printing of high quality copies              D. the increased use of the Internet

2. Environmentalists believe one possible way of dealing with the paper situation is        ____.

A. to encourage printing more quality documents     B. to develop new printers using recycled paper

C. to find new materials for making paper           D. to plant more fast-growing trees

3. Hewlett-Packard Co. has decided to develop new technologies because      ____.

A. people are concerned about the environment       B. printers in many offices are working overtime

C. small companies need more hard copies            D. they see a growing market for printers

4.What would be the best title for the text?

A. Computers and Printers                       B. E-mail and the Business World

C. Internet Revolution and Environment          D. Modern Technology and New Markets

People turn to magic chiefly as a form of insurance—that is, they use it along with actions that actually bring results. For example, hunters may use a hunting charm (咒語). But they also use their hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to hunt even more successfully than they would without it. If they shoot a lot of game (獵物), they credit the charm for their success. Many events happen naturally without magic. Crops grow without it, and sick people get well without it．But if people use magic to bring a good harvest or to cure a patient, they may believe the magic was responsible.

People also tend to forget magic’s failures and to be impressed by its surface successes. They may consider magic successful if it appears to work only 10 percent of the time. Even when magic fails, people often explain the failure without doubting the power of the magic. They may say that the magician made a mistake in reciting the spell or that another magician cast a more powerful spell against the magician.

Many anthropologists (人類學家) believe that people have faith in magic because they feel a need to believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no control over the outcome of a situation. For example, farmers use knowledge and skill when they plant their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some societies may also plant a charm or perform a magic rite (儀式) to ensure a good harvest．

1. From the passage, we can learn that the writer of the passage may be _______.

A. a hunter                                                               B. a farmer

 C. a magician                                                   D. an anthropologist

2. Which of the following can best serve as the title of the passage?

A. Magic And Hunting.

B. Magic And Farming.

C. Why Magic Works?

D. Why People Believe in Magic?

3. The underlined word “spell” (Paragraph 2) most likely means ______.

A. magic words                                      B. magic events 

C. words or expressions                 D. magicians

4. People believe in magic because________.

A. magic powers are greater than natural powers

B. magic can turn dreams into reality

C. they are not sure of themselves

D. magic can bring good results

5. Which of the following statements is NOT true according to the passage?

A. Even though magic fails, believers in magic will explain the reason.

B. Believers in magic usually overstate the power of magic.

C. People use magic to reduce their uncertainty and give them extra confidence.

D. Magic can solve problems people can’t deal with in a natural way.
