A car will come to a grinding halt if you put water in the petrol tank.
如果把水灌进油箱，汽车会猛然间停下来。 问题:come to，什么意思？

Answer 1

come to/into sth: used in many expressions to show that sth has reached a particular state（表示达到某种状态）达到，进入
grinding halt (phrase短语)：stop very suddenly,especially before it was meant to
后面是一个短语，表示是突然停下来的一个状态，所以come to是达到（某种状态）的意思。
