英语达人帮忙找下一小段话中的语法点
Dolphins find things by first making a series of clicking and whistling sounds.then,by litening to the echoes made when the sounds reflect from an object,they determine its position.this system is called echo-location.
The swimming sonar comes cheap .all dolphins ask for is 20 pounds of fish a day and a few pats on the nose.for the Navy,that's a real bargain.To actually make a system as good as the dolphins would be much more expensive,say Lt.wood.
帮忙看下以上这段话中有什么语法点.
