A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

    A private American organization called Population Action International(PAI) did the new study. It says more than 335 million people lack enough water now. The people live in 28 countries. Most of the countries are in Africa or the Middle East.

    PAI researcher Robert Engelman says by the year 2025, about 3, 000 million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.

   Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

   The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters is not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera which are carried in water.

    Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. And the report says lack of water would affect the ability to improve their economies. This is because new industries often need large amounts of water when they are beginning.

    The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water for agriculture.

    The report also says long--term solutions to the water problem must include controls on population growth.

    You may know all about vitamin C, but do you know why vitamin D is also important to your body? Experts from the Children's Hospital in Boston, US, have said that some teens don't get enough of this important nutrient.

    Vitamin D can help bones and muscles grow strong and healthy. If a person is short of vitamin D, he or she may have problems like rickets(佝偻病)and osteoporosis． Rickets is mainly found in children. Osteoporosis,the thinning of bone, is a common problem as people get older.

    Studies in these years have found that vitamin D may also have other uses. If someone is short of vitamin D, he may have heart problems or die from some cancers.

The easiest way to get vitamin D is from sunlight. But many people worry about getting skin cancer and skin damage from the sun. Also, even skin color has an influence. Darker skinned people get less vitamin D than lighter skinned people. Older people get less vitamin D than younger people. You can also get it from foods. Some food such as cheese and egg yolks (蛋黄) have some vitamin D． But most of vitamin D in the American diet comes from food like milk with the vitamin added.

    Now more doctors are testing for vitamin D in their patients. But some doctors worry that if people take too much vitamin D, it might be bad for their body. At the same time, skin doctors tell people to be careful with sunlight.

    What is eco­fashion? Eco­fashion is about making clothes that considers the environment, the health of consumers and the working conditions of people in the fashion industry.

    A closer look at the fashion industry points out many problems that are common practices in the creation of our fashions from the field to the factory. Firstly, the production of textiles pollutes the environment heavily. Cotton­planting uses pesticides; sheep­farming and wool­cleaning bring about global warming. Secondly, every stage of clothing production consumes a great deal of energy and some also involve chemicals which obviously do harm to the surroundings. In addition, there is a lot of waste produced in the process, especially in the form of polluted water. Thirdly, growing purchasing power and our shopping habits further worsen the bad effects. We are now buying clothes in increasing quantities and we are also quick to throw away clothes that have been worn only a couple of times.

    Then, how to solve the problem? To a large degree, it is the fashion producers that really have the power and the responsibility to shape our future. There are a great many ways these producers can reduce their ecological footprint, from switching to green energy and reducing energy use, through selecting sustainable materials and choosing local suppliers, to recycling and minimizing waste. On the other hand, as consumers we can all play our part by selecting environmentally friendly clothing and reducing clothing buying.

    There is some concern that eco­friendly fashions are just a trend that we will eventually grow tired of but we can make sure that doesn't happen. Now many people are beginning to shop for organic food products because the benefits of eating food free of chemicals are immediate. They relate directly to our personal health. In fact, choosing eco­fashion can also do good to our personal health, though it is mostly done by way of keeping the health of the planet.

    Growing up on a small farm, I lived a life that I took for granted. My father worked in the city as a plumber (水暖工). He was not highly educated, but he was smart, looking at problems in an engineer's way. He was a man made of leather, brass and chewing tobacco who tried to teach my brother and me useful things, including respect. He also had a temper and was strict with us for he would scold us when we made some careless mistakes. Sometimes, my father seemed like a distant enemy to me and I didn't like him very much.

    One day I came home from primary school and his car was already there. Once inside, I was told by my mother that he didn't feel well. His back hurt. My father never missed work; in fact, when he came home, he went to the barn to work even more. I remember looking at him secretly around the corner as he lay on his bed in the middle of the day.

    Later, my mother told me he got multiple myeloma (多发性骨髓瘤), a type of blood cancer. As the cancer grows, the person will shrink because the disease destroys the body's energy and the abnormal antibodies cause problems for other cells and tissue. Bones eventually look like Swiss cheese, and when they break, they may never heal. But I didn't realize that my father's time was rather limited and just treated him the same way I used to.

    For the last year of my father's life, his entire day consisted of rising from his hospital bed in the living room and walking to his chair to sit and think. He was predictably in that chair when I came home one day during the ninth grade. I do not remember where my mother and brother were, but the two of us were alone.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

    On my way home, I found a wallet which contained only three dollars and a letter that looked as if it had been in there for years. The envelope was worn and the only thing that was clear to read on it with the return address. The letter was written almost 60 years ago, which told Michael, the recipient(收信人), that the writer could not see him anymore because her mother forbade it. Even so, she would always love him. It was signed "Hannah."

    I called information in the hope that the operator could find a phone listing for the address on the envelope. The operator helped me find the woman who bought Hannah's parents' house 30 years ago. She remembered that Hannah had to place her mother in a nursing home several years ago.

    I called the nursing home. A man told me the old lady had passed away but Hannah was staying with them. Even though it was late at night, I asked if I could come by to see her. "Well," the man said hesitatingly, "if you want to take a chance, she might be in the day room watching television."

    I drove over, and the night nurse and a guard greeted me at the gate. Accompanied by the nurse, I went up to the 3rd floor. In the day room, the nurse introduced me to Hannah.

    I told her about finding the wallet and showed her the letter. The second she saw the envelope, she took a deep breath and said, "Young man, this letter was the last contact I ever had with Michael. I love him very much. But my mother felt I was too young. Michael Goldstein was a wonderful person. If you should find him," she hesitated, almost biting her lip, "tell him I still love him. You know, I never did marry…"

    I said good night to Hannah. At the gate, the guard asked, "Was the old lady able to help you?" I told him she had given me a last name which might help me find the owner of the wallet.
