※ 引述《ziew0805 (ziew)》之铭言：
: 题目在此
: She cried so hard as if it were the end of the world.
: 此句后面的were 要怎么解释 因为前面动词是过去式cried 理因来说小朋友们都认为应该
: 要用had been the end of the world 而
: 不是过去式 were the end of the world
: 以及下面这一句
: The fortune-teller looked at me as if he were able to read my mind.
: 这一句也是假设语气但前后时态却一样
: 虽然语感上知道后面要用were able to
: 不过小朋友们还是觉得前面过去 后面应该要过去完成 had been able
: 请问遇到这种情况要怎么解释 呜呜

值得注意的是第一点后半部：
They can also be used to talk about things which we know are not true.
例：
I feel as if/though I'm dying.
She was acting as if/though she was in charge
这两个例句都表示“非事实”，但时态并没有“退后一步”。
再搭配底下第二点：
When we talk about things which we know are not true, we can use a past tense
with a present meaning after "as if/though". This emphasises the meaning of
unreality.
它说we "can" use a past tense ...，因此我认为这表示“可以”，但不强制。
综合上述，我认为"as if/though"表示“非事实”时，后面的时态要不要“退后一步”
应该都可以。
若有错误还请指正。谢谢！
