constantly be learning more about the subjects that they teach with a belief that what he students regardless of then ever-ending learning;. Teachers must3. And even if a teacher is a history teacher (not too many current events when studying, say, ancient history) they need to stay up-to-date on any current discoveries that perhaps haven't been known in the past.

America. However, many are refuting (駁斥) the so-called "facts" today basing on new findings.

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably(必然地) associated with environmental damage.

Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product（GDP）. Before growth is calculated, inflation （通貨膨脹） is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.

There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.

Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.

In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable（必然的，不可避免的）. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.

For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.

1.What does the passage mainly talk about?

A. Pollution caused by plant construction

B. Effects of windmills on the environment

C. Economic growth and human civilization

D. Economic growth and environmental damage

2.What does the underlined word "They" in the third paragraph refer to?

A. Goods and products B. The industrial plants

C. Water and atmosphere D. Negative health effects

3.According to the passage, the author holds the opinion that ____.

A. economic growth should be calculated in terms of GDP

B. use of natural resources causes no damage to the environment

C. industrial manufacturing may cause damage to the environment

D. a windmill is a perfect way to produce economically practical energy

4.Which of the following shows the structure of the passage?

Starting a bank a child’s play? Absolutely, if you ask some enterprising youngsters in India, who have not only managed to establish one, but also, unlike many of the large International banks, run it successfully since 2001. What’s even more impressive is that the young bankers and their 90,004---clients(委托人) are all homeless!

The Children’s Development Khazana (treasure) opened its first branch in 2001 at a homeless shelter in New Deli as a way to help the street children protect their hard-earned money from thieves. Since then, the idea has caught on like wildfire.

Today, Khazana has 12 branches all across New Deli, with a total of Rupees 12lakh (about 22,000USD) in deposits. Not only that, there are now 77 branches in other parts of Asia, ranging from Nepal, Bangladesh and Afghanistan to the island of Sri Lanka, and even Kyrgyzstan in Central Asia. While no deposit or balance is too small for the bank, they do have strict regulations about where the money is earned from. Funds obtained by begging or selling drugs are not welcomed at this bank !

Also, unlike the real banks, all employees are volunteers , which means that they go to school or a paying job during the day and work at the bank in the evening. To ensure that everybody gets a chance to participate in running the branch, two volunteer managers are elected from the clients base every six months.

Karan, the current manager is just 14-year-old. During the day he earns a living by helping out the cleaning workmates at wedding banquets and other big parties. In the evening, he handles the deposits（存款）and withdrawals（取款）in the bank. After the bank closes, he along with an adult volunteer from the shelter head over to a regular bank and deposit the funds collected into Khazana’s interest-bearing bank account and though it started with one single purpose. The Children’s Development Khazana is today a well-developed bank, one kids can not only deposit money which earns them 5% interest, but also, request loans for family emergencies, to start a business or even to pay for school.

1.The initial aim of starting the Children’s Development Khazana is to______.
