问题解答:

我来补答
1.it's +时间段+since sb.did sth.自从……以来已经多长时间了 这是一个句型
2.这是有关虚拟语气省略if的句子,在由if引导的虚拟语气句中,谓语动词有had,were,should时,可将if省略,并将had,were,should提前,此句原句为if he had never lived,由于有had,所以把had提前变成had he never lived.
3.little,few,never,hardly,seldom,rarely,等否定和半否定的词前置,句子要部分倒装.
4.否定+时间段+before 表示“…不久就……”
肯定+时间段+before 表示“过多久才……”
所以如果你用bifore则表示他自学画画才20多岁
用until表示“直到他20多岁时他才自学画画”
5.首先不可能填have,因为主语为he
其次,这是个idea的同位语从句,主句floated为过去时,所以应该时态一致,用过去式
