be of doing sth是什么语法 - 柯帕斯英语网

Many adults' most wonderful memories are of playing baseball when they were kids.

请问句中的 are of playing 是什么语法？

我觉得这里的 are of playing baseball 可理解为在 of 前面省略了 ones / those （=memories），即：

Many adults' most wonderful memories are of playing baseball when they were kids.

=Many adults' most wonderful memories are ones / those of playing baseball when they were kids.

这里的of=about，该句可以看作主系表结构。
