■ swarm

这个不及物动词（第二类）在一般词典上的释义是“蜂拥成群（而来或而去）”，这是对的。但是这个动词的主语，既可以是动物群或人群，也可以是挤满了这个群体的地点或空间（此时该群体由介词 with 引入）。

• The flies swarmed around the meat.苍蝇成群飞来围着肉转。
• The monkeys were swarming across an artificial hill ringed by a moat.猴子在一座由壕沟围住的假山上蹦来跳去。
• The crowd swarmed into the square.人群蜂拥进入广场。
• The swamp swarmed with mosquitoes and other insects.沼泽地有许多蚊子和其他昆虫。
• The beaches were swarming with tourists.海滩熙熙攘攘挤满了游客。

后一个用法也可以转义指抽象事物。

• His head was swarming with conflicting reactions.他脑子里出现了一大堆彼此冲突的反应。
• The translation swarms with errors.译本错误百出。
