Sustainable management is seen as a practical and economical way of protecting species from dying out. Instead of depending on largely ineffective laws against poaching (偷獵), it gives local people a good economic reason to preserve plants and animals. In Zimbabwe, for instance, there is a sustainable management project to protect elephants. Foreign tourists pay large sums of money to kill these animals for sports. This money is then given to the inhabitants of the area where the hunting takes place. In theory, locals will be encouraged to protect elephants, instead of poaching them because of the economic benefit involved.

This sounds like a sensible strategy, but it remains to be seen whether it will work. With corruption in these developing countries, some observers are skeptical that the money will actually reach the people it is intended for. Others wonder how effective the locals will be at stopping poachers.

There are also questions about whether sustainable management is practical when it comes to protecting forests. In theory, the principle should be the same as with elephants --- allow logging companies to cut down certain number of trees, but not so many as to completely destroy the forest.

Sustainable management of forests requires controls on the number of trees which are cut down, as well as investment in replacing them. Because almost all tropical forests are located in countries which desperately need funds from logging, there are few regulations and motive to do this.

One solution might be to confirm wood comes from sustainably managed forests. In theory, consumers would buy only this wood and so force logging companies to go "green" or go out of business. Unfortunately, unrestricted logging is so much more profitable that wood prices from managed forests would cost up to five times more --- an increase that consumers, no matter how "green", are unlikely to pay.

Which of the following statements is true in understanding the "sustainable management"?

A. Sustainable management is usually used in commercial units.

B. Sustainable management is more powerful than laws.

C. We will probably meet many problems in the course of applying sustainable management.

D. It is likely that sustainable management will replace the laws in protecting living things.

The example of Zimbabwe is mentioned in the first paragraph is to ________.

A. prove that sustainable management is ineffective

B. explain what sustainable management is

C. show that tourism there is booming

D. illustrate that people there are good at making money with elephants

The phrase "go green" in Paragraph 5 probably means _______.

A. a company begins to make money instead of being in red

B. making the forests always green in color

C. operating in ways which do not damage the environment

D. starting from the very beginning

What is the passage mainly about?

A. What environmental protection mainly include.

B. The feasibility (可行性) of sustainable management in environmental protection.

C. Different people’s attitudes towards sustainable management.

D. How people can protect animals and plants.

What attitude does the author take towards the sustainable management?

Another eager beaver works as a salesman for a business. He   6   arrives at the office before anyone else, and is the    7   person to leave.

The man works hard, because he   8   his job. He is a true “eager beaver”.

The expression   9   the name of a hardworking animal, the beaver. Beavers are  10  creatures. They are like mice and rats, but much   11   . Some weigh more than twenty-five kilograms. Beavers have a large, black, flat tail to   12   them swim. They also have thick brown hair or fur to keep them warm in cold  13  .They have front teeth  14  enough to cut down large trees.

Beavers spend a lot of time in the water, building dams to form little   15   or pools. They work hard to cut down trees,   16   branches and put them across streams. They use their tails to pack mud on the branches to make the dams solid.  17   other animals work so hard.

And, like the animal, the expression “eager beaver” is in no danger of dying out.

I am so worried about global warming. We need stop cutting down all of the trees so that they can absorb the carbon dioxide. I think the Kyoto Protocol （京都議定書) to stop pollution is a great idea ,and I hope our country will decide to follow it, too.

                                                             — Eli S.,10,Texa

People should do all they can to help stop pollution, even if it is something as little as recycling your soda can. Every little thing helps. Maybe schools can put recycling bins in classrooms. Students can bring in all of their cans and bottles and see how many the school can collect.

                                                  — Lindsey A.,11, Massachusett

The United States should take action to help stop pollution. Since we are one of the richest countries, we should at least spend a little money to help.

                                                  — Aaron z,11,Massachusett

It is not good that the United States is not following the Kyoto Protocol. The U.S. is one of the most pollution emitting (污染物排放)countries in the world. Even if the rest of the world agrees to follow those rules, without the U. S. and its big businesses agreeing, global warming will still be a big problem.

                                                         —Augustine S.,11,Ohio

The world needs to learn more about global warming problems. If we do not do something soon then some of Earth’s coolest animals will become extinct. People should use solar power instead of things that pollute the atmosphere!

                                                    — Jillian J.,10,Pennsylvania

Global warming is very dangerous, and it must be prevented. Even if people think that it cannot be stopped ,we should  at least try. Stopping global warming is more important than keeping our businesses going. What about the penguins(企鵝)and the polar bears? We can’t just let them become extinct.

                                                        —Samantha R.,11,Illinois
