  谁能想到,庞大的鲸,(竞 竞)是海洋中最优秀的游泳健将之一。“海上霸王”虎鲸,每小时可游上百公里;上百吨的抹香鲸还是海洋中的潜水冠军呢!另外,鲸还有这样一些本领:从静止不动,立(即 既)达到全速游动,又能马上“刹车”;既能快速下潜,也能快速上浮。这些本领,是任何舰艇都望尘莫及的。

  鲸的体形特殊:硕大的头部,急速收缩的尾部,前肢演变成不大的鳍,后肢已经退化,整个身体像一(棵 颗)拉长的“水滴”。这类体形能大大减少水的阻力,十分适于在水中活动。

  舰船设计师们由大鲸的体形联想到船舶,设计了多种水滴似的鲸形船。(已 以)往一些客轮、货轮的水下部分都是刀形,现在都改成鲸形,有的超级油轮也模(仿 妨)鲸的体形,因而加快了航速。

  原先的核潜艇是雪茄形的,现在,出现了一些水滴形的现代化水下核潜艇。与雪茄形的核潜艇相比,水滴形核潜艇所受到的水的阻力可以减少很多,再加上核动力装置,功率有所增加,在水下航行时,速度有了大幅度的提高。

1.用“√”选出括号内用得正确的字。

2.写出下面词语的反义词。

收缩——(  )    增加——(  )
