have前面的主语应该是什么?
Acids are chemical compounds that,in water solution,have a sharp taste,a corrosive action on metals,and the ability to turn certain blue vegetable dyes red.
have a sharp taste的主语应该是什么?省略了什么吗?it?代表的是acids?这样说不通啊?acids是复数形式嘛,那代表的是“Acids are chemical compounds ”这个现象?如果是这样的话,Acids are chemical compounds 后面的that是什么用途啊?
