Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain cases, harmful. In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins better, improves skin, and helps reduce weight. Dr Goldfarb and Dr Negoianu say that they found little proof to back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day. It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those with certain medical conditions-drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines.com reports. The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, "but the difference in the number of headaches was o small between the two groups as to be considered unimportant." The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day. The website medheadines.com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur. We can learn from the passage that 8 glasses of water every day  _   . A) proves good for the body B) has scientific proof of harm C) is sure to reduce headaches D) is generally considered necessary
D


(Question)
In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built. The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move. "We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged. One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the  flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger  he could move. Thus, he slowly developed a code of communication with his wife. He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed. Which of the following is true of Washington and his father? A) They are hardworking and courageous. B) They are stubborn and bold. C) They are creative and persistent. D) They are curious and modest.

Question: It's exciting to imagine how future humans will have solved the problems we have now, or what amazing new inventions will make our lives more convenient and interesting. We asked top scientists to share their predictions on what the world will be like in a century. If they're right, the 2114 is going to be really cool. 1. Robots will do your chores and more Robots will be doing most of our jobs, from building homes to teaching math. There are already robots that clean floors and pump gas. In the future they will be more complicated and useful. Unfortunately, with robots taking all the jobs, unemployment will be high. 2. You will read minds. Speaking of being social, we will communicate in an entirely different way. Forget texts and emails. Mind-reading technology will allow us to send thoughts to each other without speaking a word. We will also be able to send thoughts to objects around us. (Instead of pressing "start" on the microwave, you could just think "start.") Meanwhile, chips implanted(in our brains will improve memory and intelligence. 3. Your car will drive you Today, around 30,000 Americans die in car accidents each year. One hundred years form now, accidents will be a thing of the past. According to Mark Safford, consultant or the U.S. Department of Transportation, future cars will drive themselves. These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds. 4. You will eat fake meat. Raising animals is not an efficient way to produce food, and it harms the environment: Cows, chickens, and pigs eat a lot, and then we have to deal with all that poop(. What's more, that poop can up poisoning lakes, rivers, and streams. Today, scientists can "grow" meat in a lab from animal cells, but it's expensive and not very delicious. In the future, they will have perfected the process. You'll order hamburgers that come from factories, not cows. Scientists may even find ways to make lab-grown meat tastier and healthier than the real thing. According to the passage, what is likely to happen when robots become more common in the future? A) People will be much lazier. B) More people will lose their jobs. C) People may become physically weaker. D) More people may become less intelligent.

B
