For medical students, real experience begins not in a classroom but at a teaching hospital. These doctors in training are guided. But sometimes accidents happen and the students get injured. For example, they might stick themselves with a needle while treating patients. Such needle sticks are common. But a recent study found that medical students often fail to report them. Failing to report an injury like this can be dangerous if a patient, or a medical worker, has an infectious disease. Researchers at Johns Hopkins University in Baltimore, Maryland, did the study, which involved a survey answered by almost 700 surgeons in training in the United States. Almost 60% said they had suffered needle stick injuries when they were in medical school. Many said they were stuck more than once. Yet nearly half of those whose most recent incident happened in school did not report it to a health office. If they had, they would have been tested to see if they needed treatment to prevent an infection like HIV or hepatitis. Most known cases of HIV or hepatitis are reported, but other possible infections often are not. Martin Makary, the lead author of the study, says medical students who are stuck put themselves and others in danger from infectious diseases. Doctor Makary said, "A needle that goes through the skin needs to be as sharp as possible." Doctors in training may have to do hundreds of stitches in some cases to close the skin after an operation. Doctor Makary said, "I support using _ tip needles which are considered safer. This needle is still sharp enough to go through body tissue, but it does have a blunt tip, so that if it accidentally goes into my finger, it's much less likely to hurt me." How common are needle sticks among health care workers? An estimated 600,000 to 800,000 of these and similar injuries are reported each year in the United States. But Doctor Makary says the real number may be much higher. The study advises doctors to protect their hands by wearing two sets of gloves. It also urges hospitals... If they report needle stick injuries, medical students will _ . A) receive treatment B) be forbidden to use sharp needles C) spend more time on training D) receive tests

studying 20 minutes a day for 20 days. You'll start with the basics and move on to more complex reading comprehension and critical thinking strategies. Please note that although each chapter can be an effective skill builder on its own, it is important that you proceed through this book in order, from Lesson I through Lesson 20. Each lesson builds on skills and ideas discussed in the previous chapters. As you move through this book and your reading skills develop, the passages you read will increase both in length and in complexity. The book begins with a pretest, which will allow you to see how well you can answer various kinds of reading comprehension questions now, as you begin. When you finish the book, take the posttest to see how much you've improved. The text is divided into four sections, each focusing on a different group of related reading and thinking strategies. These strategies will be outlined at the beginning of each section and then reviewed in a special "putting it all together" final lesson. Each lesson provides several exercises that allow you to practice the skills you learn. To ensure you're on the right track, each lesson also provides answers and explanations 'for all of the practice questions. Additionally, you will find practical suggestions in each chapter for how to continue practicing these skills in your daily life. The most important thing you can do to improve your reading skills is to become an active reader. The following guidelines and suggestions outlined will familiarize you with active reading techniques. Use these techniques as much as possible as you work your way through the lessons in this book. According to the passage, which of the following is NOT true? A) Each chapter has an internal relationship with the previous chapter. B) The texts are arranged in the order of length and complexity. C) Different reading strategies are listed at the beginning of each section. D) The author suggests using the book selectively according to readers' level.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. All of the following indicate that the monkey has almost restored to her original physical state except the fact that A) her heart beat again. B) she regained her normal breath. C) she rejected a penicillin injection. D) she acted as lively as a healthy monkey.
