Question

阅读理解 　　It seems strange that while three-quarters of the world’s surface is covered with water, getting an adequate(足够的)supply of it that’s fresh, clean, and safe to use for drinking, cooking and washing, is one of the most important problems that faces humanity．Most of the earth’s water is salt water in the oceans, only three percent is fresh and only a small part of that is possible．It may be trapped deep underground, and anyway unequally exist around the globe, so droughts and floods happen now and then．Of the remaining fresh water, much is polluted and dangerous to use． 　　A large part of UNICEF’s(联合国儿童基金会)work is bringing safe water to people and educating them in basic health care．Some diseases spread by polluted water are the most common causes of death and illness in children under five in the developing world． 　　Although water gives life, it can also carry some kinds of disease－a leading cause of blindness among children．Mosquitoes, and flies that live near in water bring yellow fever, malaria(疟疾)and sleeping sickness, so good piped water supplies are needed to reduce the need for people to gather in such an area． 　　In the country, women and children spend a major part of their time going out to collect water, often walking many miles each day to provide just the limited family needs for cooking, washing and drinking．And they can’t carry much while walking over rough fields bearing a heavy bucket(桶)． 　　Because children have to play their part in family life, and that includes getting water, they may be unable to go to school, or be so tired when they get there that they have difficulty learning．They may even have to spend the whole day without a drink as there may not be any clean water there, either． 　　Last year, UNICEF aimed to get almost 90000 water systems set up, to benefit 20 million people, working where it is most badly needed, often just to ensure keeping alive．A well may mean the difference between life and death． (1) What is the main reason for the inadequate supply of fresh water? [　　] A． Most of it is polluted． B． Most of it is almost impossible to get． C． Most of it is in the sea． D． Floods and droughts have taken place time and again． (2) Which of the following statements is NOT true?
