词义辨析

v. (动词)

reduce by, reduce to

• 这两个短语都表示“减少”,前者用于表示减少的数量; 后者用于表示减少的程度。

reduce, decrease, diminish, lessen

• 这组词都可表示“降低”或“减少”。其区别在于:decrease指各种事物逐渐减少、逐渐衰弱的过程; lessen指减轻强度和减缓烈度,也可指从整体上减去部分或在程度上、数量上的减少; diminish指可以看得出的“缩小”“缩减”; reduce指缩小事物的范围、强度、数量等,也可指级别、地位或经济条件的降低。例如:
• Decrease the dose of medicine when you feel better.你感到好些就减少药剂用量。
• The number of fighters had now diminished to two, but the hilltop remained in our hands.现在战士只剩下两个人了,但我们仍然占领着山头。
• Good lubrication will reduce friction.良好的润滑会减少摩擦。
• The noise lessened as the plane got further away.飞机逐渐飞远了,噪音也就减弱了。

decrease，diminish，lessen，reduce，dwindle

• 这些词的共同含义是“减少，变少”。
• decrease指逐渐地、不断地减少。
• diminish侧重大小、数量和重要性的不断减小，强调减小的部分。
• lessen普通用词，与decrease近义。指数目、程度、价值、实力等的减少。
• reduce普通用词，含义广。指数量、程度的降低或减少。
• dwindle与decrease同义，指逐渐减小，但强调变得越来越少终至全无。

常见错误

v. (动词)

1. 他们被减薪了。

   误 Their salaries were reduced down.

   正 Their salaries were reduced.

   正 Their salaries were cut down.

   析 reduce本身就表示减少,所以无需再用down这一副词。
