___the expence, I ____ a round -the -world tour
A if it hadn't been for, would have taken
B were it not, would take

答案是A 请问这里为什么是用过去虚拟而不是将来虚拟B呢?

都可以,但是答案B有问题,应该是were it not for

英语语法：____ the expense,I ____ a round-the-world tour. I will ____ the world in the future.空格处为何填“tour”,不能填“travel” were it not expense .I take a round the worl tour I want to take a tour around the world.around是什么词性 a round the world.怎么译? Round The World 歌词阅读 Round The World tour of the world是什么意思 If I were rich,I______travel round the world the world goes round and travel round the world 造句 tour the world 这句语法对吗?
