If asked, he lies about his age.这里省略的是"If he is asked"还是"If he was

Question

英语语法：请问这里可以是虚拟语气吗？

Answer 1

这里不是虚拟语气，因为he lies about his age（主句），里面的动词是第三人称单数，是一般时态
所以这里省略的是If he is asked
If he is asked=If asked
If asked, he lies about his age.
如果被问到的话，他就谎报自己的年龄。

Answer 2

应该是If he is asked，这样才能前后时态一致。
当然用虚拟语气就更规范了，例如：
If he had been asked, he would have lied about his age.本回答被提问者采纳
