Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn't have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy. In order to raise the efficiency of the water supply, measures should be taken to _ . A) guarantee full protection of the environment B) centralize the management of water resources C) increase the sense of responsibility of agencies at all levels D) encourage local and regional water resources

As hand-held devices such as smartphones are becoming more common, users are reporting some new physical problems. Florida chiropractor Dean Fishman began noticing an increased number of patients talking about neck and shoulder pain. He discovered these symptoms were due to the overuse of hand-held devices, particularly the action of bending the neck, and then _ the term "Text Neck." As if the painful symptoms weren't bad enough, Fishman warns that an untreated case of Text Neck could lead to permanent spinal damage. Other doctors have warned about "iPad Hand," a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain. In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic principles: Avoid awkward positioning. Don't strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren't leaning over for a long period of time. Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes. When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle. Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you'll be resting both hands on the keyboard. And since you won't be holding the tablet, you'll be less likely to experience hand or arm pain. What kind of product for hand-held devices does the writer discuss? A) One for recording. B) One for charging. C) One for telephoning. D) One for typing.

Ques: As a society we might want to rethink the time and money spent on education,so that these resources can benefit a greater percentage of the population.Ideally,both high schools and colleges can prepare individuals for the ever-changing roles. High school degrees offer far less in the way of preparation for work than they might,or than many other nations currently offer,creating a growing skills gap in our economy.We encourage students to go on to college whether they are prepared or not,or have a clear sense of purpose or interest,and now have the highest college dropout rate in the world. We might look to other countries for models of how high schools can offer better training,as well as the development of a work ethic and the intellectual skills needed for continued learning and development. Meanwhile,the liberal arts become more important than ever.In a knowledge economy where professional roles change rapidly and many college students are preparing for positions that may not even exist yet,the skillneeded is one that prepares them for change and continued learning. Learning to express ideas well in both writing and speech,knowing how to find information,and knowing how to do research are all solid background skills for a wide variety of roles,and such training is more important than any particular major in a liberal arts college.We need to continue to value broad preparation in thinking skills that will serve for a lifetime. Students also need to learn to work independently and to make responsible decisions.The lengthening path to adulthood appears exacerbated by parental involvement in the college years.Given the rising investment in college education,parental concern is not surprising,but learning where and when to intervene willhelp students take more ownership of the outcomes of these increasingly costly educations. What suggestion does the author offer to parents? A) Rethinking the value of higher education. B) Investing wisely in their children's education. C) Helping their children to bring their talent into full play. D) Avoiding too much intervention in their children's education.
