rocked

rock, stone

这两个词都可表示“石头”。它们的区别是：

stone指体积较小的天然石块; rock指体积巨大的天然石块。例如:

The wall is made of stone.这堵墙是石头块砌成的。

He built his house on rock.他在岩石上建起了房子。

rock, quake, quiver, shake, shiver, tremble

这组词都可表示由于震动或受刺激而引起的振动或颤抖。它们的区别是：

在表示因寒冷或恐惧而发抖时, shake, tremble, quiver和shiver常可互换。rock和shake强调外界因素所致, quake则强调自身因素引起。在摇动的幅度上, rock>quake>quiver>shiver。在摇动的频率上, shiver>tremble>quiver>rock。在程度上, quake最弱,几乎难以觉察。tremble强调无法克服性,而shiver则强调短暂性。用于指声音时, tremble只表示声音断断续续; quiver则指音调高低或声音强弱方面的颤抖。例如:

His hands were trembling〔shaking〕 from cold.他冷得两手直哆嗦。

He was quaking〔shivering〕 in his boots at the thought.他一想到这些就怕得发抖。

The ground quaked under his feet.大地在他脚下震动。

His insides quaked at the thought.想到这一点,他心里就发慌。
