Astronomy is the oldest science known to man....

Astronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone.

The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn(土星) had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture(海王星), the last of eight planets to be discovered, was not seen until 1846.

Before the spectroscope(分光镜), man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn’t know that radio noises came from far out in space.

Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy.

1.. Thousands of years ago, people observed the stars with the limitation of their _____.

The oldest and most common source (来源) of renewable energy known to man, biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere —- from trees and grasses to agricultural and city —- life wastes —-biomass promises to play a continuing role in providing power and heat for millions of people around the world.

According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide, because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun’s energy. In this way, biomass serves as a sort of natural battery(电池) for storing the sun’s energy. As long as biomass is produced continuously —-with only as much grown as is used— the “battery” lasts forever.

According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008—-although the numbers aren’t all in yet—-wind power probably took over first place because of the rapid development of wind farms across the country.

Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner’s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.

1.Why is biomass considered as “a sort of natural battery”?

A. It burns simply plant matter.

B. It stores the energy from the sun.

C. It keeps producing electricity.

D. It produces zero carbon dioxide.

2.We learn from the text that in 2008 ______.

A. 0.5~0.9 of power supply came from biomass

B. biomass might become the main energy source

C. there was a rapid growth of electricity production

D. Wind power would be the leader of renewable energy.

3.Why does the author encourage power plants to use biomass?

A. To save money.

B. To prevent the waste of energy.

C. To reduce pollution.

D. To increase production safety.

4.Where does the text probably come from?

A. A book review. 　 B. A business report.

C. A research plan. D. A science magazine

The pomegranate is one of the oldest known fruits. Pomegranates are found in ancient writings and pictured in the ancient art of many cultures and religions. The pomegranate is also a symbol of health, fertility and long life.

Experts think the pomegranate is native to northern India, Pakistan, Iran and Afghanistan. Today it also grows in Southeast Asia, the western U.S., Armenia and parts of Africa, among other places.

The skin of a pomegranate is strong. It can be red, purple or orange-yellow. The inside is filled with beautiful dark red seeds that shine like rubies. It is not easy to get them out. But the reward is great.

Health benefits

The pomegranate grows on trees. Parts of the pomegranate tree and fruit are used to make medicine.

The pomegranate is used for many conditions. However, the U.S National Institutes of Health says there is not enough scientific evidence to rate pomegranates as effective for any of them.

Still, in traditional medicine, the pomegranate is used for conditions of the heart and blood vessels, including high blood pressure and "hardening of the arteries."

The jewel-like seeds of the pomegranate are loaded with many nutrients and chemicals called antioxidants(抗氧化剂). These antioxidants remove poisons from the body.

The antioxidants found in pomegranates may help remove build-up of damage in blood vessels. So, it is a very heart-healthy fruit.

Antioxidants slow the progression of age-related sickness and may slow the growth of cancer cells. Men who have prostate cancer may benefit from a daily serving of pomegranate juice.

Pomegranates are used for weight loss and used as a treatment for sore throat. Pomegranates are also high in vitamin K, phosphorus, magnesium, calcium, zinc and iron.

Let's just say pomegranates are loaded with great things for the inside of your body.

Beauty benefits

But let's not forget the outside, too!

Pomegranates are great for the skin. They protect the skin by encouraging new skin growth, healing wounds and repairing tissue. Pomegranates protect the skin against sun damage as well. They may help skin look younger by providing moisture and elasticity.

Recipes for pomegranates

But how does one eat a pomegranate?

Pomegranates seeds are both sweet and tart. A thick liquid, or syrup, from the pomegranate tastes great with lamb, pork or chicken dishes.

Pomegranate seeds provide extra flavor to salads and other vegetable dishes. The seeds are also delicious in rice and grain dishes. And, of course pomegranates make great desserts. In the U.S., pomegranate juice is often added to sparkling drinks, drinks called smoothies and alcoholic drinks.

Watercolour is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colours found in the earth with water.

Fresco, one of the greatest of all art forms, is done with watercolour. It is created by mixing paints and water and applying these to wet plaster. Of the thousands of people who stand under Michelangelo’s heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolour painting in the world.

The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolour was used mainly for doing sketches or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolour as a serious art form. The English have a widely-known love for outdoors and also small private pictures. The softness of watercolour had a remarkably strong attraction for them.

The popularity of watercolour continued to grow until the twentieth century. The United States passed England as the center for watercolour, producing such well-known watercolour artists as Thomas Eakins and Andrew Wyeth.

1.The purpose of the passage is to introduce _____.

A. the gradual weakness of fresco painting

B. oils’ power or influence over watercolour

C. the discovery of watercolour in England

D. the start and development of watercolour

2.In the 16th and 17th centuries the artists thought _____.

A. watercolour was softer, and thus better

B. oil painting lasted longer, and was better

C. watercolour wasn’t fit for finished works

D. watercolour was too hard to use in any works

3.According to the passage, watercolour painting was put back in England because ____

A. it was easy to use outdoors              B. it was a strong medium

C. it was extremely bright in colour        D. it was suited to popular tastes

4. What would the next paragraph most probably deal with?
