世界水资源的缺乏World Water Shortage A new study warns that about thirty percent of the world's people may not have enough water by the year 2025. 一项新的研究结果提出警告：到2025年，世界上将有30%的人没有足够的水饮用。 A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East. 这项研究是由美国一家名叫“人口行动”的私立机构进行的。报告说现在世界上有三亿三千五百万人没有足够的水。这些人主要分布在非洲或中东的28个国家。 P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-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. 人口行动组织的研究人罗博特.安格曼说，到2025年大约三十亿人缺水。
至少还有其他18个国家将可能面临同样严重的水短缺问题。人类对水的需求不断上升，但地球上水的还是保持不变。 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. 安格曼先生说，水短缺的国家的人口增长率要高于世界其他地区的人口增长率。他还说这些国家的人口出生率将持续增长。 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 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. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning. 报告表明，在未来，水资源的缺乏可能会导致一些严重的后果。
首先它可能会产生更多的健康问题。水资源的缺乏就意味着饮用水不再有保障。安格曼先生说，诸如霍乱等在水中传播的疾病会使世界出现许多问题。水缺乏也会引起更多的国际纷争。各国可能由于水而发动战争。现在有些国家，例如埃及，荷兰，柬埔寨，叙利亚，苏丹和伊拉克等，60%的纯净水是从国外进口的。报告认为水缺乏将影响发展国家发展经济的能力。这是因为新工业在开始阶段经常需要大量的水。 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 of agriculture.

对不起，没图，你自己排版吧~sorry~~~~A man was hit by a cab in the street. He was brought to the hospital. His wife who was standing up by his bed, said to the doctor: ＂I think that he is very ill.＂ ＂I am afraid that he is dead.＂said the doctor, Hearing this, the man moved his head and said: ＂I'm not dead. I'm still alive.＂ ＂Be quiet, ＂said the wife. ＂the doctor knows better than you！＂ 一个男人在街上被出租车撞倒送进了医院.他的妻子站在他的床前对医生说：＂我想他伤得很厉害.＂医生说：＂我怕他已经死了.＂听到医生的话，这个男人转动着头说：＂我没死，我还活着.＂妻子说：＂安静，医生比你懂得多.＂＂When we reach the station, that will be it! ＂we cry. ＂When I'm 18. ＂＂When I buy a new 450SL Mercedes Benz! ＂＂When I put the last kid through college. ＂＂When I have paid off the mortgage!＂＂When I get a promotion.＂＂When I reach the age of retirement, I shall live happily ever after! ＂Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The true joy of life is the trip. The station is only a dream. It constantly outdistances us. ＂Relish the moment ＂is a good motto, especially when coupled with Psalm 118:24:＂This is the day which the Lord hath made;we will rejoice and be glad in it. ＂It isn't the burdens of today that drive men mad. It is the regrets over yesterday and the fear of tomorrow. Regret and fear are twin thieves who rob us of today.So stop pacing the aisles and counting the miles. In stead, climb more mountains, eat more ice cream, go barefoot more often, swim more rivers, watch more sunsets, laugh more, cry less. Life must be lived as we go along. The station will come soon enough.It was there!It is Sport Day.All the student are very excited .Su Hai and Su Yang are watching the running race.Su Hai wants to take some photos.She is ……I've Just Bitten My Tongue ＂Are we poisonous?＂ the young snake asked his mother. ＂Yes, dear,＂ she replied - ＂Why do you ask?＂ ＂Cause I've just bitten my tongue！ ＂ 我刚咬破自己的舌头 “我们有毒吗？”一个年幼的蛇问它的母亲。
“是的，亲爱的，”她回答说，“你问这个干什么？” “因为我刚刚咬破自己的舌头。”（1）The rat-catcher can't catch caught rats. (2〕Six silly sisters sell silk to six sickly senior citizens. （绕口令）It was the first day of our summer holiday. All of us were very happy. Why? Because we have one months to do things we love to do. We are free.Although we have some homework. But we can finish them in several days. And the rest time we can make good use of. My god! We have been very tired after hard studying. In winter holidays, I want to have full sleepand eat good food in order to replenish myself. Last but not the least, I will have a good rest.这是我们暑假的第一天。我们大家都非常高兴。为什么呢？因为我们有一个月做我们都爱做的事。我们很空闲，虽然我们有一些功课。但是，我们可以完成它们的若干天。
其余的时间我们可以好好利用。我的上帝！我们已经很疲惫后很难学习。在冬季假期，我希望能有充分的很好吃的食物，以补充自己。最后但并非最不重要，我会好好休息。
