很高兴能够在这里回答你的问题,填写
确实选D
这个句子的时态是将来完成时
首先发生在飞机着陆时,现在还没有着陆,所以要用将来时
正如你所说,for 3 hours,所以要用完成时态
所以用将来完成时态 will have doneD选项明明是将来完成进行时啊说明一直在等了三个小时用将来完成时进行时也是没有问题的
By the time your plane lands tonight ,I____at the airport for 3 hours
By the time your plane lands tonight ,I____at the airport for 3 hours
A had waited
B have been waited
C had been waiting
D will have been waiting
为什么是D,for 3 hours不是完成时态的标志吗?
A had waited
B have been waited
C had been waiting
D will have been waiting
为什么是D,for 3 hours不是完成时态的标志吗?
