1·Using special stains, one can see that some bacteria have attached to them wavy-looking "hairs" called flagella. Others have only one flagellum.
用特殊的着色剂后，你会发现有的细菌上长着不少波状的“毛发”即鞭毛，而有的细菌只有一根鞭毛。
2·In recent experiments they proved that they could stop and start the bacteria's flagella simply by exposing them to two different kinds of substances.
在最近的实验中他们证明了他们可以仅仅通过施加两种不同物质来停止和启动细菌的鞭毛。
3·As a result, bacteria have developed a unique way of swimming: using tiny rotary motors called flagella, which resemble corkscrews.
结果细菌进化出独特的游泳方式：使用叫做鞭毛的像螺旋开瓶器的微型旋转马达。
4·Filling a volume of just 0.043 cubic micrometres, they consisted of thin rods with up to three long whip-like attachments called flagella.
它们只占0.043立方微米的空间，是由三个被称鞭毛的长鞭状附件组成的细条。
5·The rotation of flagella pushes the bacteria through the water.
鞭毛的旋转可以推动细菌在水中行进。
