Drop 既可作及物动词也可作不及物动词,常用的意思有“下降,落下,减少,降低”;fall 只能当作不及物动词使用,常用的意思有“跌倒,下降、减少,落下”。这两个词在日常的对话和写作中出现频率很高,但二者之间在表达“落下,降落”时有微妙的区别。首先看 drop,它可作为及物或不及物动词来使用,常用的意思有“下降,落下,减少,降低”。Eg: The weather forecast says the temperature is going to drop below zero tonight.天气预报说今晚气温会降到零度以下。Please be careful not to drop the glasses.请千万小心别把杯子摔掉了。Travel agents drop prices to boost bookings during off-peak seasons.旅行社在淡季减价以促预定销售。Scientists are looking at what causes the sea level to drop.科学家在研究海平面降低的原因。接着来看fall,它只能被作为不及物动词来使用,常用的意思有“跌倒,下降、减少,落下”。Eg: It is slippery on the road, be careful not to fall.路上有些滑,小心别摔倒。The government predicts the unemployment rate will continue to fall in the next quarter.政府预计失业率在下个季度会继续降低。The snow started to fall as I was leaving.我走的时候雪已经开始落了。通过以上的例句不难看出 drop 和 fall 当作不及物动词使用时有以下几个区别:第一,fall 有“摔倒”的意思,而 drop 则没有;第二,在两个词表示“落下,降落”时,drop 特别强调描述人为的、有空间高度下落的动作,而 fall 则可以指任何物体或人在没有受控制下、失去平衡而倾倒或受重力影响而“自然下落”。Eg: I dropped the glasses; they fell on the hard floor and broke.我把杯子摔掉了,它们落在地上后碎了。
