When many people see birds cleaning their feathers, they attribute it to vanity on the part of the bird. But, in reality, what they are doing is maintaining their wings, the instruments that they depend on for safe flight. If a bird’s wings are not in perfect condition, the bird either won’t be able to fly or won’t be able to control its flight. That is why after a long flight and even throughout the day, you will see them cleaning their feathers.
Most birds, if they get a chance, will take a bath at least once a day. They do this to get rid of the dust that has accumulated in their feathers throughout their flight s during the day. In dry or desert areas, birds will not always be able to find water in which to bath, but they still need to clean their feathers. What many birds will do is to take dust baths. They will roll around in dust until it covers their feathers. They will stand up, shaking the dust out, and then clean their feathers with their beaks (鸟嘴) as usual.
Baths are important for another reason. During the course of the day and night, many parasites (寄生虫) are attracted to birds. Bugs, mites, fleas and so on will try to reach birds and suck from their blood. Daily baths help to keep the parasites to a minimum.
Some birds, especially those that spend a lot of time in or around water, have skin glands (皮肤腺) that produce oil. After bathing, these birds will squeeze the glands to spread the oil over their wings to keep them free of water.
If you are a bird lover and have bird houses in your yard, it can be good to go to the extra step, providing a bird bath. Once the birds in your neighborhood discover it, you will be surprised at how popular it becomes as they periodically stop by to take their daily bath.

The young people who talk of the village as being “dead” are talking nothing but nonsense, as in their hearts they must surely know.
No, the village is not dead. There is more life in it now than there ever was. But it seems that “village life” is dead. Gone for ever. It began to decline about a hundred years ago. When many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember what “village life” meant in the early years of the present century. It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp oil and coal.
Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed（展现）to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make “village life” and “town life” almost alike. Now with the highly developed science and technology and high-level social welfare（福利）for all, there is no point whatever in talking any longer about “village life.” It is just life, and a better life.
Finally, if we have any doubts about the future, or about the many changes which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. 0bviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.
1．By saying that village is not dead, but “village life” is dead, the writer suggests that_______ .
A．those young people who talk of the village as being “dead” are wrong
B．the two statements are against each other
C．“village life” today is rather uninteresting
D．“village life” today is no longer like what it used to be
2．As is suggested in paragraph 2, villages in the past______________.
A．lived a simpler life than villagers today
B．knew fewer people than villagers today
C．found it difficult to enjoy themselves
D．like to wash themselves with cold water
3．The expression “…there is no point whatever in talking about…” in paragraph 3 means that______________.
A．there is no end to the talking about …
B．it is harmful to talk about …
C．it is not meaningless to talk about …
D．there is no reason for talking about …
4．What does the writer think of the “village life today”?

Since the 1950s, most of the stars of pop music have come from Britain and America. Howver, in the last ten years, when many different kinds of music have established themselves on the pop scene, more and more stars have come from other countries.
Pop music changes all the time and new stars appear and become famous. For a musician to stay popular and still produced good, original music over a long period of time, is a sign of true star.
Most stars start their careers in a simple way---- playing in unknown night clubs or dance-hall where people want to dance to the music, not listen to it. They may have continued doing this for many years untill they get a “break”---- a chance to perform in a well –known place or get a recording contract. To become a star is the aim of every singer or musician and the dream of many a pop-crazy teenager.
However a group or star makes it to the top, they can be sure that their lives will change once they are successful. Ordinary teenagers living at home with their parents may suddenly find themselves rich enough to buy their own houses. An established superstar may be able to buy several.
Despite the large amount of money that are earned, life at the top is not easy for many stars.. The pop scene is hard work and many stars need to spend a lot of time away from home. For a lot of them, this means they have no home life and their personal relationships suffer. Despite great public success, life at the top can be very lonely.

Time is valuable but limit. There’s a famous saying, “Time is money”, this shows the
important of time. When time has gone, it will never return back. It’s a pity when many
people make poorly use of time. They spend their precious time oversleeping, drinking and
traveling. They don’t realize wasting time is equal to waste part of their life. They always
regret having made little achievement so far. Therefore, we should form the habit valuing
time. Don’t put off that can be done today until tomorrow. Laziness will not only bring us failure, but also lead us on the road of poverty and even death.

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).
But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.
The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.
Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.

1.The debate has been raging for years over the safety of, and necessity for, childhood vaccinations, which has been so much so that it is termed “The Vaccine War”. The debate has only a few moments that might be inspiring to those who have been following this now familiar issue.
2.There are certainly benefits of using a star in a film. It makes the film easier to market. Stars also help sell more tickets and drive DVD sales, which are a big part of studio revenue. However, a star does not guarantee success. The simple fact is that if you pay a star a great deal of money for a film that people don’t want to see, then it won’t work.
3.They are barely in their twenties and are already multimillionaires. At the age when many people are looking for their first job, the youngsters of The Sunday Times Rich List are buying country estates or jetting off to their overseas homes. Daniel Radcliffe, for example, who plays Harry Potter, has a fortune of £42 million, at 20.
4.Millions of jobless Americans, who might be suffering in anxiety and lacking a sense of security, are showing up at emergency rooms of state-owned hospitals, contributing to a longer waiting time and a higher risk of cursory treatment by overworked doctors and nurses.
5.Alice Miller, a psychology expert, who died at 87 at home in Provence, France, on April 14,repositioned the family as a central place of abnormal psychological function with her theory that parental power and punishment lay at the root of nearly all human problems.
