阅读文段,回答问题。

  清晨,我在门前散步,突然旁边的梧桐树上落下了什么东西,同时还有刺耳的吱吱声,我跑了过去,那是一只蝈蝈正在啄着处于绝境的蝉的肚子。我明白了,这场战斗发生在树上,发生在一大早蝉还在休息的时候。不幸的蝉被活活咬伤,猛地一跳,进攻者和被进攻者一道从树上掉了下来。有时我甚至还看到蝈蝈非常勇敢地纵身追捕蝉,而蝉则惊慌失措地飞起逃窜。就像鹰在天空中追捕云雀一样。但是这种以劫掠为生的鸟比昆虫低劣,它是进攻比它弱的东西,而蝈蝈则相反,它进攻比自己大得多、强壮有力得多的庞然大物,而这种身材大小悬殊的肉搏,其结果是毫无疑问的。蝈蝈有着有力的大颚、锐利的钳子,不能把它的俘虏开膛破肚的情况极少出现,因为蝉没有武器,只能哀鸣踢蹬。

1.本段介绍了蝉哪些方面的特点?

答:________________________________。

2.作者在介绍蝈蝈捕蝉时,拿鹰追捕云雀相比。那么蝈蝈与鹰相比有何异同点?

答:________________________________。
