she is wet ,she must have been caught a cold in the rain.
为什么要用完成时态的被动语态？为什么不用 must be caught
she is wet ,she must have been caught a cold in the rain.这个句子不正确。应该是：
she is wet ,she must have caught a cold in the rain.不用被动语态。追问
she is wet ,she must have caught a cold in the rain.不用被动语态。追问
she is wet ,she must have been caught in the rain
追答这样可以用被动语态。must +现在完成时，表示对过发生的事的推测

个人感觉，must be caught 也是可以的，完成时更好一些，表示对现在造成一定影响（感冒）。
