When Paul was a boy growing up in Utah, he happened to live near a copper smelter（炼铜厂），and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest．One day a young visitor looked at this wasteland and called it an awful area．Paul knocked him down．From then on, something happened inside him.

Years later Paul was back in the area, and he went to the smelter office．He asked if they had any plans or if they would let him try to bring the trees back．The answer from that big industry was “No”.

Paul then went to college to study the science of plants．Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds．It would be a waste of his life to try to do it．Everyone knew that, he was told．Even if he was knowledgeable as he had expected, he wouldn’t get his idea accepted．

Paul later got married and had some kids．But his dream would not die．And then one night he did what he could with what he had．As Samuel Johnson wrote, “It is common to overlook what is near by keeping the eye fixed on something remote．Attainable good is often ignored by minds busied in wide ranges.” Under the cover of darkness, he went secretly into the wasteland and started planting.

And every week, he made his secret journey into the wasteland and planted trees and grass．For fifteen years he did this against the plain common sense．Slowly rabbits appeared．Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing.

Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has．It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child.

       B．the economy of Utah depended wholly on the copper smelter

       C．no laws were made to protect the environment against pollution

       D．he had determined to stop the copper smelter polluting the area

       B．Because he was interested in planting trees since he was young.

       C．Because he wanted to get more knowledgeable people to help him.

       D．Because he thought his knowledge would make his advice more persuasive.

About 90 percent of Chinese believe the polarization(分化) between the rich and poor is “serious” in China, according to a survey conducted by China Youth Daily. And more than 80 percent of the respondents(对象) surveyed said something must be done to narrow the expanding gap between the rich and poor, while 14.1 percent said it was necessary.

The polarization has aroused wide concern among the public in recent years. The State Development and Reform Commission(国家发改委) said the Gini Coefficient had reached 0.47 for China, up from o.29 two decades ago. Usually, a country with a number above 0.4 is warned to pay attention to the income inequality problem.

To find out the people’s view, the survey covered 10,250 respondents, between the ages of 20 and 30 with a college education and a monthly salary between 1,000 and 3,000 yuan. Surprisingly, most disagreed with the view of experts who claim the urban-rural difference is causing the widening gap. More than 70 percent of the respondents believed that “ the group of special interests” is the prime reason for the polarization, followed by “people in power” 68 percent, and “bosses” 50 percent.

Another unexpected finding is that almost all agreed that a good educational background and knowledge were not the decisive factors in gaining wealth. About 95 percent said rich people are not necessarily those who are able to speak English or have a college education.

Today in China, rich people , accounting for 10 percent of the population, control 45 percent of the total social fortune, and poor people, also 10 percent of the population, only control 1.5 percent, according to an investigation published by the National Bureau of Statistics last June.

It can be inferred that the Gini Coefficient ( in paragraph 2) would probably be _____.

   A. the unit used in advanced mathematics

   B. the degree of a country’s development

   C. the level of the citizen’s living standard

   D. a measure of income inequality

Experts hold the view that the main reason for the polarization is _____.

   A. the urban-rural difference             B. the group of special interests

   C. the people in power                  D. the bosses

Which of the following can show the correct proportion(比例) of the social fortune among population?

 

What’s the best title of the passage?

   A. Close the Gap between the Rich and Poor

   B. Surveys conducted by China Youth Daily

   C. Higher education, Higher pay

   D. Rich-Poor Divide Serious, Study Finds

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP section and pays for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits.

When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

The article is intended to           .

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

Passive RFID tags chiefly consist of           .

A. scanning devices              B. radio waves              C. batteries            D. chips

Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become more fierce.

C. Because their private lives will be greatly affected.

Lichens (地衣) are difficult to see. They don’t move. They often mix into the living place. You might not even recognize one if you are looking right at it.

Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms (微生物) almost everywhere — from deserts to rainforests, and from Antarctica to Africa. They’ve traveled in outer space, and some scientists think there might even be lichens on Mars.

What you probably don’t realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus (菌类) and an alga (藻类). Neither of these organisms is a plant, so the lichen isn’t a plant either.

Through photosynthesis (光合作用), the alga gets the sun’s energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus.

Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another. By putting together a lichen family tree, they hope to understand why so many different types of lichens have grown in so many places around the world.

Many researchers are trying to understand basic facts about the organisms and their connections. Researchers are also using lichens to examine the health of the environment.

What do we know about lichens according to the passage?

A. They will die if they leave Earth.

B. There are more lichens than plants on Earth.

C. They look similar to the environment around them.

D. They are too small to be easily seen by people.

What does the second paragraph mainly talk about?

A. The way lichens live.

B. The natural environment of lichens.

C. The way lichens work as organisms.

D. The family tree of lichens.

Which of the following statements is NOT the scientists’ purposes of studying lichens?

A. To understand basic facts about them.

B. To creat a lichen family tree.

C. To understand how lichens are related to each other.

D. To understand why lichens can live in different places.

We can know from the passage that __________.

A. lichens can be used to better understand the environment

B. lichens don’t have any differences in colors or sizes

C. lichens don’t use photosynthesis like a green plant

D. scientists have discovered every kind of lichen
