题文
阅读理解。 Traditional surgical procedures require surgeons to make large incisions (伤口) in a patient's body in orderto gain access to the organs inside. It was once common for heart surgeons, who perform highly specializedand complex procedures, to make long incisions in a patient's chest and then split the breastbone to reach theheart. Patients who undergo surgery are often at the risk of infection (感染), as bacteria can infect the cut inthe skin. In addition, there is often a lengthy recovery period. A surgical technique known as "keyhole surgery" has become more common in recent years. In general,the surgeon will make a couple of small incisions around the area where the operation I'm going to be performed. Tubes are pushed into the holes, and a tiny camera is put into the body. The camera is attached toa large monitor screen and the doctor can e it while performing the operation. In addition to the camera, doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push itto the right. Another new machine called the "da Vinci Surgical System" has been tested in hospitals in the US-Unlike keyhole surgery, this robot's moving parts are designed to copy man's hand and wrist movement, thus providing better control and nsitivity. Sitting at a console (控制台) a few feet from the patient, the surgeoncan control the instruments by moving highly nsitive pads. The area of the body is enlarged on a screen,which gives surgeons a view similar to that of a traditional surgical procedure. The da Vinci Surgical System has been welcomed as revolutionary by many surgeons. Patients with riousillness must still undergo major surgery, but the smaller incisions typically mean a shorter recovery time. Onthe downside, some operations have taken up to fifty minutes longer becau surgeons are inexperienced atusing the new technology. As surgeons become more familiar with the machines, the time needed for surgical procedures is likely to decrea. 1. What can be learned about the traditional surgery according to the passage? A. Long incisions are made in a patient's chest. B. It often takes a longer time to do an operation. C. The cost of the traditional surgery is very high. D. The incision is likely to be infected after the operation. 2. Which of the following is one disadvantage of keyhole surgery? A. It requires the u of long thin tools and a tiny camera.B. The doctor cannot view the inside of the patient's body clearly. C. The direction in which a doctor moves the surgical tools is opposite. D. A tiny camera has to be inrted into the patient's body in advance. 3. The da Vinci Surgical System differs from keyhole surgery in that it _____. A. requires that a surgeon make more small incisions on a patient B. reduces the amount of time it takes to perform a surgical procedureC. allows the surgeon to u the surgical instruments more nsitively D. gets rid of the need for surgeons to make large incisions on patients 4. The passage mainly tells readers about _____. A. the challenges brought about by new technologyB. the application of new technologies in modem surgery C. the reflections on the development in medical science D. the benefits and drawbacks of the da Vinci Surgical System 题型:未知难度:其他题型答案

考点
据考高分专家说,试题“阅读理解。 Trad.....”主要考查你对 [健康环保类阅读 ]考点的理解。 健康环保类阅读健康环保累阅读概念:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分: 第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容; 第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明; 第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。 从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。【阅读策略】 1、概要(Summarizing): 阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。 2、组织(Organization): 阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。
