B It keeps your insides from falling out. It helps you warm up when you are cold, and it can cool you off when you are hot. It lets you feel things by touch. What is this Your skin, of course! What does your skin ask for in return for all the wonderful things it does Just a little care! So let’s learn how to take good care of our skin. Like the heart and stomach, your skin is an organ(器官). In fact, it is the largest organ in your body. Unless there’s a problem, you may not think about your skin very much. But skin has an important job to do. Your skin is protecting you. Your skin keeps you from getting sick. When you take care of your skin, you are helping your skin do its job. Taking care of your skin today will help you have no problems in the future. Clean skin is happy skin! One simple way to take care of your skin is to keep it clean. Keeping your hands clean is very important. When washing your hands, use warm water. Wet your hands, and then use soap. You should wash your hands carefully everywhere. You’ll also want to use warm water, but not too hot, when you take a bath. Use soap to clean your body. Don’t forget under your arms and behind your ears! Your face needs attention, too. It’s a good idea to wash your face once or twice a day with warm water. What does this passage mainly talk about ( )

A. Taking care of your skin.
B. Your skin.
C. An important organ.
D. Keeping yourself from getting ill.

Text 4 Picture-taking is a technique both for reflecting the objective world and for expressing the singular self. Photographs depict objective realities that already exist, though only the camera can disclose them. And they depict an individual photographer’s temperament, discovering itself through the camera’s cropping of reality. That is, photography has two directly opposite ideals: in the first, photography is about the world and the photographer is a mere observer who counts for little; but in the second, photography is the instrument of fearlessness, questing subjectivity and the photographer is all. These conflicting ideals arise from uneasiness on the part of both photographers and viewers of photographs toward the aggressive component in "taking" a picture. Accordingly, the ideal of a photographer as observer is attracting because it implicitly denies that picture-taking is an aggressive act. The issue, of course, is not so clear-cut. What photographers do cannot be characterized as simply predatory or as simply, and essentially, benevolent. As a consequence, one ideal of picture-taking or the other is always being rediscovered and championed. An important result of the coexistence of these two ideals is a recurrent ambivalence toward photography’s means. Whatever are the claims that photography might make to be a form of personal expression just like painting, its originality is closely linked to the power of a machine. The steady growth of these powers has made possible the extraordinary informativeness and imaginative formal beauty of many photographs, like Harold Edgerton’s high-speed photographs of a bullet hitting its target or of the swirls and eddies of a tennis stroke. But as cameras become more sophisticated, more automated, some photographers are tempted to disarm themselves or to suggest that they are not really armed, preferring to submit themselves to the limit imposed by pre-modern camera technology because a cruder, less high-powered machine is thought to give more interesting or emotive results, to leave more room for creative accident. For example, it has been virtually a point of honor for many photographers, including Walker Evans and Cartier Bresson, to refuse to use modern equipment. These photographers have come to doubt the value of the camera as an instrument of "fast seeing". Cartier Bresson, in fact, claims that the modern camera may see too fast. This ambivalence toward photographic means determines trends in taste. The cult of the future (of faster and faster seeing) alternates over time with the wish to return to a purer past when images had a handmade quality. This longing for some primitive state of the photographic enterprise is currently widespread and underlies the present-day enthusiasm for daguerreotypes and the work of forgotten nineteenth-century provincial photographers. Photographers and viewers of photographs, it seems, need periodically to resist their own knowingness.

阅读下面短文,回答文后问题。 随着科技水平的提高和人们对物质世界更深层次的认识,医用生物材料作为材料大家族中与人们的关系最直接、最密切的一个分支,也得到了迅猛的发展。人们现在可以制造出各种生物医学材料来修复和替代人体器官,提高人们的生活质量,延长人们的生存空间。 介入医学是一门融医学影像学和临床治疗学为一体的新兴边缘科学,涉及人体消化、呼吸、心血管、神经、泌尿、骨骼等多个系统疾病的诊断和治疗。生物医学材料的研究和发展对介入医学的普及和发展起着举足轻重的作用。尤其是为一些不治之症或难治之症,如癌症、心血管疾病等,开拓了新的治疗途径,而且简便、安全、有效、并发症少。在介入疗法中,插入身体的导丝、导管壳、导管、血管支架,球囊导管,以及人体内各腔道支架,都是由医用生物材料制成的。 利用医用生物材料制成的支架,不仅可以扩张血管,还可以为患食道肿瘤的病人服务。把这些支架放入患处,可使患者恢复进食和排泄,减轻患者的病痛,提高生存质量。又如治疗血管肿瘤,随着肿瘤的增大,会压迫血管,造成供血不足,甚至威胁生命。利用导管把为肿瘤提供营养的血管堵住,肿瘤就会由于得不到营养而死亡、脱落。 系统性红斑狼疮,是一种自身免疫性疾病。目前的研究表明,患者自身免疫系统发生紊乱,产生过多的抗DNA抗体及抗体附属物,从而损害组织器官。生物医学材料的发展和基因工程在医学上的应用,为治疗这种疾病提供了新的思路。人们制造了一种高分子材料,经碳化后形成微小的碳颗粒,通过生物提取技术,从小牛胰腺中提取DNA进行分离纯化,制成具有生物活性的DNA免疫吸附剂,然后组装成DNA免疫吸附剂的血液净化装置。 在实际医疗过程中,使患者的血液作体外循环,在通过DNA免疫吸附装置时,血液中的抗DNA抗体就会被吸附剂所吸附,从而达到治疗的效果。从理论上讲,如果我们能够找到合适的DNA,就可以通过血液换流的方法治疗任何免疫系统疾病, (选自王渝生主编的《改变人类的科学活动》,上海科学技术文献出版社,2004) 理论上,通过血液换流的方法治疗免疫系统疾病的最为关键的因素是:

A. 血液净化装置
B. 合适的脱氧核糖核酸(DN
C. 足够的生物活性
D. 精密的分离纯化技术
