B.to be sent
C.to have been sent

为什么选C?从哪看出来!

-So you are28,______?
A.was given birth;aren't you
B.was born;did you
C.was given birth to;are you
为什么不选B?而选C?

Answer 1

第一题可以把句子倒过来看 是
Mr.Li was fortunate to have been sent to the USA for further study.
所以一定要有to 就可以把A D排除了.
而用完成时关键是因为讲话人要强调事情和现在的关系,即因为李先生被送去了美国现在已经不在这里了.
第二题选 C是因为 are you 和前面的you are 28谓语保持一直,至于.was given birth to的确很奇怪,不过至少还是符合语法.
