Question

几道选择题,希望有好的解释. 1. ________,we probably won't have all that much time for a holiday.
A.as it happens B.as it turned out C.If it happens D.If it turns out
2.You don't have to wear your seat-belt if you are reversing your car,______ you are making a local delivery using a special vehicle.
A.and B.but C.or D.for
标准答案是A;C,为什么呢

Answer 1

1、as it happens 中 as 有although的意思,表示“即使、就算”； happen表示事情发生 ,turn out表示事物出现.
2、"if you are reversing your car,______ you are making a local delivery using a special vehicle."这是一个条件状语从句.逗号前后两句是并列的,主句中“you don't have to...”表示否定,选择or.
