Question

1 but,favourite eating varieties like cod and skate which grow to unnatural sizes.grow后面加个to什么意思？
2,Three factors have caused these fish to grow so large .grow前面为什么加to
3.the plentiful supply of food thrown overboard by the crews on the rigs。为什么用overboard什么意思？

Answer 1

首先明确grow是一个vt.和vi.动词,因此它后面可以接宾语和不定式形式.
1.to就像Grow to 18 years old 一样表示到达某一地点,程度,这里当然是指长到了不寻常的尺寸.但是这里并不是不定式形式,to是个介词,表示指向.
2.这里grow是vi.形式,so large表示程度,可以看做一个状语副词.修饰长的程度.
3.overboard指的是越过船舷,因为船员要喂鱼的话要将鱼食扔入水中,这里的board指的是船,over只从上空（不接触所越过物体）飞过,因此overboard指的是从船上面扔过去,也就是越过了船舷的意思.
