347. She keeps a supply of candles in the house in case of power failure.
译文
她在家放了些蜡烛,以备停电时用。点睛
a supply of为固定短语,意为“一批”。in case of意为“防备;万一;如果”,后面可以接名词或动名词等。如:The doctor asked us to call him during the night in case of necessity. 医生告诉我们,如果夜里有必要,就打电话给他。
考点归纳
与in case of类似的短语还有in case,它的用法十分广泛。in case/just in case引导目的状语从句,意为“以免;以防”。如:
You must be quiet in case the fish are frightened. 钓鱼时要静默不语,免得将鱼吓跑了。
in case接条件状语从句,意为“如果;万一”。如:
In case we fail, we won't lose heart. 万一我们失败,我们决不会失去信心。
in case作副词性短语,常置于句末,表示事先准备或预防的措施,意为“以防万一”。如:
She ought to be there in case. 她应待在那里,以防万一。
