英語六級-完形語法關鍵句360. The outbreak of the Second World War was

360. The outbreak of the Second World War was quickly followed by an increase in the number of day nurseries in almost all countries, as women were again called upon to replace men in the factories.

譯文　隨著二戰(zhàn)的爆發(fā)，婦女們又被召去工廠以填補男性勞動力的缺失，緊接著幾乎所有國家的日托數(shù)量都有所增長。
