Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world. About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria. The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles of silver. The pages can be used as filters to remove harmful microorganisms that can pollute drinking water. The filter kills the organisms that pass through it. Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned. Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages. "The idea of classic texts--that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through _ " she says. Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful. Water for Life, a non-governmental organization, has provided financial support for the project. Question: What do we learn about the book from the text? Options: A: It sells well around the world. B: It has pages with several functions. C: It is about environment protection. D: It can treat about 100 liters of water.

Read the article and select the best answer. Article: There is nothing in the Hippocratic Oath that tells doctors what to do when they make a mistake with a patient. Nor is there much on this subject in medical school curriculums or in training programs. _ Much was made of the Institute of Medicine's 1999 report that 44,000 to 98,000 people die each year in hospitals from preventable medical errors, many of them made by doctors. The report stated much first-hand information to address the problem, but there was little discussion about how doctors, when they have made mistakes, should deal with their patients, Everyone assumes that the ever-present threat of accusation has made doctors more anxious about admitting error, and no doubt it has, But doctors have always been tight-lipped about their mistakes, in part to preserve an illusion(,) of medical omnipotence Studies suggest that patients are less likely to accuse doctors when they apologize for mistakes, and many hospitals now encourage their physicians to admit their errors. According to an supportive group called The Sorry Works! Coalition, 16 states have already passed laws giving doctors legal immunity for their apologies to patients. Of course, there are plenty of doctors with a nice bedside manner who can get away with bad treatment. How else to explain patients who often line up in court to support doctors accused of malpractice ? The surprising truth is that many patients have a hard time knowing whether they are really getting good medical care. Because so many diseases change randomly over time, patients sometimes spontaneously improve despite improper treatment. On the other hand, a patient who receives exemplary medical care may fare badly simply because the illness is hard to treat. In other words, doctors are often praised or blamed, when the outcome is in fact a chance event. Many, perhaps even most, medical errors probably have little ill effect and go unnoticed by patients. Many lawyers would disagree, but doctors ought to let their patients know when they've made a mistake; it humanizes... Question: According to the passage, which of the following is TRUE? Options: A: The doctor made the mistake deliberately so they do not apologize. B: Doctors never tell the patient they have made a mistake. C: The patients won't forgive the doctor if he make the mistake. D: The patient will usually forgive the doctor when the mistake are not intentional.

Read the article and select the best answer. Article: Every day my husband parked his car in the same open-air car park in Zimbabwe. On this particular day, he had been running to his car with a pile of office papers under his arm. As he opened the car door, he suddenly lost control of his body. He felt a stabbing pain in his arm, and became totally breathless and lost consciousness. As he fell down, half in, half out of the car, his last thought was "what a way to die". A young woman getting into her own car in the deserted car park noticed what was going on and at once ran to my husband's aid, trying to bring his life back.

Fearing an ambulance would take too long to arrive, she felt it better to get to the hospital as quickly as she could. She raced through traffic lights sounding her car's horn and rushed into the hospital, calling out, "I have an unknown man here who I think is having a heart attack. Having realized he was in capable hands, the woman returned to the car park, found his keys on the ground, collected his papers and piled them in the car.
