题型:单项选择题

病毒比细菌小得多,只有用能把物体放大到上百万倍的电子显微镜才能看到它们.一般病毒,只有一根头发直径的万分之一那么大.病毒比细菌简单得多,整个身体仅由核酸和蛋白质外壳构成,连细胞壁也没有.蛋白质外壳决定病毒的形状.它们中有的呈杆状、线状,有的像小球、鸭蛋、炮弹,还有的像蝌蚪.病毒不能单独生存,必须待在活细胞中过寄生生活,因此各种生物的细胞便成为病毒的“家”.寄生在人或其他动物身上的病毒称为动物病毒,人类的天花、肝炎、流行性感冒、麻疹等疾病,动物的鸡瘟、猪丹毒、口蹄疫等,都是因为病毒寄生于人体及畜禽细胞而引起的.寄生在植物体上的叫植物病毒,烟草花叶病、大白菜的孤丁病、马铃薯的退化病等等都是由植物病毒引起的.还有一类病毒生活在细菌体内,以茵为食,因此被称为噬菌体,是细菌病毒.病毒所依赖的活细胞叫寄主,一般每种病毒都有特定的寄主,例如脑炎病毒只能在脑神经细胞内寄生.寄主养活了病毒,而病毒却“恩将仇报”,反过来危害寄主.以人体为寄主的脊髓灰质炎病毒,可以导致小儿麻痹症的发生;由流行性腮腺炎病毒引起的腮腺炎,至今还使许多儿童深受其害.1801年,拿破仑派遣了2.5万名士兵进军西印度洋的卡伊德岛准备 * * 当地黑人.由于军队染上了“黄热病”,结果病死2.2万多人,只好不战自败.直到1902年才查明:引起“黄热病”的元凶是黄热病毒.病毒的寄生性为消灭病毒带来了困难,因为消灭病毒或多或少都要伤害寄主.只有在人们认识到动物自身具有免疫机能之后,才逐渐掌握了对付病毒的办法______人工免疫.最简单的生命体是类病毒,它的个体只有病毒个体的七十分之一,只有核酸,别无其他组成物质.类病毒与病毒性质相似,也具有寄生性,可以引起小麦矮化病等症.

根据本文,下列符合病毒描述的是 ()

A.病毒由核酸、蛋白质外壳、细胞壁等构成

B.病毒往往只有类似蝌蚪的一个形状

C.病毒要用放大到上百万倍的电子显微镜才能看到

D.与细菌相比,病毒往往要复杂得多
