In Greece there are the ruins of a bathtub and water system built over 3, 000 years ago. The Romans had warm public baths. In some as many as 3, 000 persons could bathe at the same time. Treating disease by bathing has been popular for centuries. Moden medical bathing or hydrotherapy, first became popular in Europe and by the late 1700’s also became popular in the United States. For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to be clean was avoided and perfunewas often used to cover up body smells ! By the 1770’s doctors began to say that soap and water were good for health. They believed that it was good for people to be cleaned. Slowly people began to bathe more frequently. During the Victorian Age of the late 19th century, taking a bath on Saturday night became common. In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “The Great Unwashed! In one American city, for example, a person could only take a bath every thirty days !That was a law! Frequency of bathing today is partly a matter of habit. People know that bathing for cleanness is important to health. Doctors know that dirty bodies increase the chance of diseases. Consequently, in the United States, people generally bathe often. Some people bathe once a day at least. They consider a daily bath essential to good health. 查看更多

  Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.

    The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).

    Who is to blame?

    Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim(受害者)of habitat destruction.

    Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”

    In China the new reserve(保护区)itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.

"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.

The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average(平均水平) of 11% and the rate in most developed countries.

    Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment(投资) in such reserves at all levels.

1.What do we know about the IUCN?

   A. A union for listing animals and plants on the earth

   B. A group of volunteers who are interested in wildlife

   C. An organization concerning the protection of rare species' survival

   D. A government made up officials, scientists and experts

2.What can be concluded from the passage?         

A. All the protection methods can’t work.       

B. The IUCN does most of the protection.

C. The efforts China makes has paid off.   

D. Enough is done in wildlife protection.

3. Which of the following is not the cause of the disappearance of the animals?

   A. Bad weather     B. Over-hunting    C. Warmer oceans    D. Habitat destruction

4.Which of the sentence is NOT true?

       A. China has been paying great attention to protecting the natural resources.

       B. China has set up a lot of natural reserves.

       C. The natural reserves in China cover more than 15 percent of the nation's land area.

       D. The rate of China's natural reserves is lower than the average of the world.
