Theyhadtoputoffthesportsmeeting______theheavyrain.()A.becauseB.becauseofC.untilD.unless
They had to put off the sports meeting ______the heavy rain.()
A.because
B.because of
C.until
D.unless
答案:B.
because是连词,其后接句,becauseof是复合介词,其后接名词、代词、动名词、what从句等,until直到,unless,除非.根据They had to put off the sports meeting ______the heavy rain,可知因为大雨,他们不得不推迟运动会.这里表示原因,又rain是名词,所以用because of.故选B.
