Experts do not really know when people began keeping fish as pets. But they say that people have been interested in fish for thousands of years. Some say the ancient Sumerians were the first civilization to keep fish in ponds more than four thousand years ago. The Chinese kept and studied carp and goldfish more than one thousand years ago. The ancient Romans kept eels as pets. And the Greek philosopher Aristotle made what is believed to be the first known study of sea life, including sharks and dolphins.

Keeping fish at home in small water tanks called aquariums is extremely popular today. And everyone seems to enjoy visiting huge public aquariums that have opened around the world.

By the middle of the eighteen hundreds, science had shown that plants, fish and other sea creatures could survive together under water. So it was no longer necessary to change the water in a tank for the fish to live there. This led to the building of the first public aquariums.

The first aquariums opened in London, England in 1853. in the next fifteen years, other aquariums opened in Europe and the United States. By 1928, there were about forty-five public aquariums.

The Monterey Bay Aquarium has been recognized as the first aquarium in the United States and it shows visitors the underwater life in the bay. The Georgia Aquarium opening in 2005 says it is the largest in the world. It has more than one hundred thousand sea animals in thirty million liters of water including two whale sharks---the world’s largest fish.

Another aquarium re-opened in 2005 in Camden, New Jersey. The Adventure Aquarium first opened in 1992. It spent about fifty million dollars expanding its building and improving its exhibits.

Aquariums provide the public with many chances to experience life under the sea. They can be found in most areas of the world. People might even want to start an aquarium at home and join the millions of people around the world who keep fish as pets.

1.Which aquarium opened again after its rebuilding ?

A. The Monterey Bay Aquarium.           B. The Adventure Aquarium.

C. The Georgia Aquarium.                    D. The first aquarium in London.

As we all know ,trees are important to our life. They provide us with food, wood and most importantly, oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria in water.

The discovery was made by some scientists and high school students who were seeking for a natural water filter(过滤器)—one that could help people in developing countries that don’t have access to modern water systems.

The researchers, led by Rohit Karnik, a professor ,decided to turn to trees for help because they were able to allow liquid to flow through while blocking out air bubbles(气泡）.

They began by cutting 1.5-inch-wide sections of tree bark from the branch of a white pine tree. The researchers then tested the wood’s filtering ability by pouring water containing red dye particles(染料颗粒)of different sizes through. To their surprise, they found it was effective in trapping all the particles. Encouraged, the team did another experiment, this time with water containing bacteria. Sure enough, the bark held back 99%of the bacteria, allowing only 1% to flow through.

Mr. Karnik said the bark was able to filter water containing much smaller particles. This means that it can be used to get rid of most of the bacteria. However, what troubles them is that tree bark cannot hold back viruses, which tend to be much smaller.

Though the experiment is successful, we must remember one thing—the bark only works when damp. This means that before this natural filter can be put to practical use, the researchers will have to figure out how to keep the bark damp, or find a way to keep the bark’s great filtering ability even when it’s dry.

But the study is not done. The researchers plan on testing other types of trees, including those flowering trees. They think those may be more effective in trapping smaller particles and even viruses.

1.How will the discovery affect the world?

A. No harmful bacteria will be found in water.

B. There will be no water pollution around the world.

C. More pine trees will be planted around the world.

D. Clean water will be more accessible in developing countries.

2.What problem troubles the researchers when using the trees bark as a water filter?

A. Viruses cannot be prevented.

B. Tree bark should be wet.

C. It’s hard to remove air bubbles.

D. Not all bacteria can be held back.

3.Why does the team plan to do other experiments?

A. To find other natural water filters.

B. To improve the filtering ability of other trees.

C. To find a way to keep the bark wet.

D. To test the filtering ability of other trees.

4.In which column of a newspaper can we read this text?

A. Culture.　　 B. Science.

C. Lifestyle.　　 D. Society.

Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.

In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.

Experts, however, say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.

Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.

In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.

1.What is probably talked about before this passage?

A. How many vitamins a person’s body needs.

B. How many vitamins some foods contain.

C. The benefits that vitamins bring to our health.

D. What people should do to stay healthy.

2.Vitamin supplements are popular with people because ________.

A. people mistakenly think that they are good for their health

B. they contain more vitamins than the foods people eat

C. food does not provide enough vitamins people need

D. people fear that a lack of vitamins will lead to disease

3.From the passage, we can learn that medical experts advise people _________.

A. never to take any vitamin supplements

B. to depend only on food for their vitamins

C. not to take any vitamins together with medicines

D. to consult doctors before taking vitamin supplements

4.For people who lack Vitamin B-twelve, they can eat more from _______.

A. sweet potatoes　　 B. green leafy vegetables

C. pork products　　 D. eggs
