If you are interested in sea creatures,you don't have to go to swim in the sea. You can enjoy underwater life in 1        way―by visiting an aquarium.

Experts do not know 2        people began keeping fish as pets. The Chinese kept and studied carp and goldfish over one thousand years ago. The ancient Romans kept eels. And the Greeks made the first study of sharks and dolphins. By the middle of the 1800s,science 3       (show) that plants,fish and other sea creatures could survive together under water. So it was no 4        necessary to change the water in a tank for fish to live there. This led to the building of the first public aquarium.

Today,millions of people visit aquariums in more than thirty countries. An official of Maryland says his organization 5      (approve) fortyone aquariums in the USA in the past few decades. One of 6       (famous) aquariums is in Monterey,California. All over the world,it 7      (recognize) as the finest one. It was in a building that 8        to be a cannery. This was 9        workers prepared fish and placed them in cans to be sold.

What's more,the Monterey Bay Aquarium is caring about twentynine penguins,which are kept until they are ready 10       (return) to the nature reserve.

Have you felt that you are out of style,either in language,or in ways of expending,or in songs,or even in food and clothing? A kind of culture comes into your life and the world quietly or on a large scale. It has been said that yesterday's cultural icons are on the ash heap today and what's "in" today will be "out" tomorrow. 1       But practically speaking,how does one find time to keep up with all of the trends and changes that take place? I suggest not wasting all of your energy trying！

Allow me to explain. The adolescent years has always been about the process of individuation,separating from parents and becoming an independent adult. Over the past 50 years,youth culture has become more easily identifiable. 2       This makes it difficult for the average parents to keep up. Yet,whatever forms today's youth culture takes,it is important to remember that adolescents use youth culture to express that process―nothing more and nothing less.

Reading a good book on youth culture,periodically thumbing through a magazine marketed to teens or occasionally watching an hour of television programs aimed at teens are all worthy endeavors to keep up with today's youth culture. 3       It is an organization that does an excellent job of watching global youth culture trends that most parents would find difficult to track by themselves.

While keeping track of trends in youth culture throughout the country and the world is good parenting practices,you are supposed to approach them. 4       For instance,it may become trendy on the east coasts for teenage guys to wear Capri pants,but it could also be a trend that never makes it to Sioux Falls. So,if you happen to live in a place that is less trendy by nature,I would not advise that parents spend time preparing against the " Great Capri Pant Invasion". 5      

   A. So don't let the speeding changes make you lose the directions.

   B. Still,changes within youth culture itself are rapid.

   C. Keeping up with what's going on at your kids' school just down the road is the most important and practical thing to do.

   D. Another great resource is the Center for Parent/Youth Understanding.

   E. The youth culture nearly takes the leading part in the gap between young and old.

   F. It is wise for parents to be students of youth culture.

   G. You should also know what youth culture matters most to you and your kids.

There have been many great inventions,which1       ( change) the way we live. The first great invention was one 2        is still very important today―the wheel. This made it easier to carry heavy things3       (travel) long distances. For hundreds of years after that there were few inventions that have made as much effect as the wheel. There was little unknown land4       (leave) in the world. People did not have to explore much any more. They began to work instead to make life better.

In the second half of the 19th century many great inventions 5       (make) . Among them were the camera,the electric light and the radio. These all became a big part of our life today. The first part of the 20th century 6        more great inventions. The helicopter in 1909. Sound movies in 1926. The computer in 1928,and jet planes in 1930. This was also a time when a new material was made. Nylon came 7        in 1935. It changed the kind of clothes people wear. The middle part of the 20th brought new ways to help people get 8        diseases. They worked very well. They made people healthier and let them live long lives. By the 1960s most people could expect to live to be at least 60.  By this time most people had a very good life. Of course new inventions continued 9       (make) . But man now had a wish to explore again. The world is known to man but the stars are not yet. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries,10       (include) China and Japan,have made their steps into space.

As the pace of life continues to increase,we are fast losing the art of relaxation. Once you are in the habit of rushing through life,being on the going from morning till night,it is hard to slow down. 1       Stress is a natural part of everyday life and there is no way to avoid it. 2       A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health. 3       Some people are not afraid of stress,and such characters are obviously the prime material for managerial responsibilities;4 When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between " flight or fight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered. Since we can't remove stress from our lives        (it would be unwise to do so even if we could) ， 5      

   A. It seems strange that this phenomenon appears in our modern society.

   B. In fact,it is not the bad thing as often supposed to be.

   C. we need to find ways to deal with it

   D. But relaxation is essential for a healthy mind and body.

   E. We might do more exercise to strengthen our mind and body.

   F. others lose heart at the first sign of unusual difficulties

   G. The amount of stress a person can stand depends very much on the individual.

As a resident of Hubei Province which is called "the province with thousands of lakes"， my heart hurts for the polluting South Lake. We should of course do something of it right now.

First,the environmental protection department should make strict laws. Then the fish owners must deal the dead fish in time. Third,the citizens who live near the lake must forbidden to pour pollutants into the lake. What's more,the government should educate the citizens the important of protected environment and put forward various ways to dealing with the problems which may be causing by our ignorance and indifference.

If everyone is responsible for the South Lake and do which is right,there is no doubt whether it will turn back to a pretty diamond of Wuhan.

There is now growing 1          ( aware) of the comfort of our study environment. Nevertheless,do the heating system operating for a whole day really make 2       ?Proponents of having the heating system think of 3           ( stay) a cozy place as human instinct. Moreover,it also comes with a good mood for the stressful learning courses. Hence,it is said 4          (ensure) for every freezing winter day.

Despite its evident privileges,we can't ignore the potential consequences 5        are in the majority. With all the doors and windows 6       (close) when an air conditioner is in operation,the 7       (restrict) air circulation may give rise to the growth of bacteria. Many people may 8         (infect) with flu or other diseases.

Furthermore,9       (stay) inside for quite a long time will surely weaken our ability to cope with cold weather. Much electricity is used to keep the air conditioner running,which will probably cause environmental problems.

With all these factors taken into account,it's high time we10       (turn) off the heating system to live in harmony with nature.

For one thing,I take a optimistic and positive attitude the Internet. And I am marveling at computer's amazing calculation speed and enhanced intelligence which has changed the way which people communicating with each other. What's more,that makes great contribution to information spreading and global modernization.

But for another,I strongly oppose being addicted to the Internet too much. Internet obsession had become a more noticeable problem. More and more people are getting hook on the Internet and become slaves to chat rooms and games. Not only will it do harm to our health,but also it will make us to lose our passion for the real world.

A latest survey shows that the health of Chinese youngsters 1       (decline) . What we can't deny is the fact 2        there exists a great demand to keep healthy for them.

As 3       ( illustrate) by the survey,the phenomena such as obesity and short?sightedness 4       (increase) dramatically now.

The second thing we must focus on is 5        it is that makes the results come 6        being. As it puts,too much homework and 7      (lack) sleep do help decline the health state of Chinese youngsters. Especially 8       (owe) to their lack of exercises,the problem of overweight has become more and more serious.
