347. She keeps a supply of candles in the house in case of power failure.
譯文
她在家放了些蠟燭,以備停電時用。
點睛
a supply of為固定短語,意為“一批”。in case of意為“防備;萬一;如果”,后面可以接名詞或動名詞等。如:
The doctor asked us to call him during the night in case of necessity. 醫(yī)生告訴我們,如果夜里有必要,就打電話給他。
考點歸納
與in case of類似的短語還有in case,它的用法十分廣泛。
in case/just in case引導(dǎo)目的狀語從句,意為“以免;以防”。如:
You must be quiet in case the fish are frightened. 釣魚時要靜默不語,免得將魚嚇跑了。
in case接條件狀語從句,意為“如果;萬一”。如:
In case we fail, we won't lose heart. 萬一我們失敗,我們決不會失去信心。
in case作副詞性短語,常置于句末,表示事先準備或預(yù)防的措施,意為“以防萬一”。如:
She ought to be there in case. 她應(yīng)待在那里,以防萬一。
