A new study gives us the warning 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 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. 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. 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 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. 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. The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow... _ are expected to have severe water problems by the year 2025 A) No countries B) 18 countries C) 46 countries D) 28 countries

You may have noticed that you feel hungry a lot. This is natural----during teens, a person's body needs more nutrients to grow. Snacks are a great way to satisfy that hunger and get all the vitamins and nutrients your body needs. But you need to pay attention to what you eat. Filling your stomach with a lot of fries after class may give you a short-time help, but a snack high in fat and calories will only slow you down in the long time. To keep energy levels going---and avoid gain weight---keep away from foods like candy or soda. Look for foods like bread and grains and combine them with some food like peanut butter or low-fat milk or cheese. Choosing healthy snacks means shopping smart. Be careful of the health instructions on food bags. Here are some things to watch out for. That something is "all natural " doesn't necessarily mean that it's nutrients. For example, "all natural" juice drinks or sodas can be filled with sugar (which means they'll be high in calories and give you little nutrition.) A granola bar is a good example of a snack that people think is healthy. Although granola bars can be a good source of certain vitamins and nutrients, may also contain a great deal of fat, including a particularly harmful type of fat called trans fat. Check the Nutrition Facts instructions on the bag to be sure. Which of the following snacks is unhealthy according to the text? A) Peanut butter B) Candies and soda C) Low-fat milk D) bread

Q: Residents along Australia's east coast awoke in the morning to an orange sky as winds swept millions of tons of red dust from the country's inland and dumped it on Sydney. Tanya Ferguson,living in Sydney,saw that the room was completely orange.She thought there was a bush fire.But when she went outside,the entire city was covered in a film of orange dust. "It was like being in the outback ,but it was right here in the city,"she said On that day,a big dust storm swept through Sydney.It covered the city in orange dust for about eight hours,making landmarks such as the Sydney Opera House and Harbor Bridge invisible. The storm affected the transportation system.Flights were delayed.Roads were busy as drivers struggled in the difficult conditions.Children and the elderly were told to stay indoors until the dust had cleared.Later strong winds blew it out to the sea and up the coast. No one was hurt in the storm,though health officials answered hundreds of calls from people with breathing difficulties.Emergency services responded to hundreds of calls about tree branches brought down by strong winds. Dust storms are common in the Australian outback,where the land is arid .But the storms rarely reach the coastal regions. Officials said it was the worst dust storm of the past 70 years.Air pollution levels were 15,500 micrograms of pollutants per cubic meter. "On a clear day the pollutants are around 10--20 micrograms per cubic meter,"said Chris Eiser of the NSW department of the environment. Experts said that dry conditions in the outback and strong winds caused the sandstorm. "Ten very dry years over inland southern Australia and very strong winds have combined to produce the storm,"said Nigel Tapper,an environmental scientist at Monash University, Australia. Which of the following is TRUE? A) The dust storm didn't blow up to the coastal regions of Australia. B) The level of air pollution was very high due to the dust storm. C) People called the emergency service because they had got lost. D) Children stayed indoors for the schooling had been cancelled.

Q: The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem. As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today's ly high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs. For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor people are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are old. Many companies do not hire people over 65 years old the normal retirement age. Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job. Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer. At the present time, the government thinks it can reduce poverty in the country in the following ways. First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer be below the poverty line. Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer. Then it is more likely that they can find jobs. Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government... Which of the following is NOT true? A) Ten percent of the Americans live a poor life. B) Poor people are those who live below the poverty line. C) The poverty line rises as the general standard of living rises. D) The poverty line tends to be at the same level.
