这句话：

Tom has faced his share of controversies.

意思是：

Tom 也经历过不少争议。
或者更自然地说：Tom 也没少遇到争议。

逐部分看

Tom
= Tom

has faced
= 面对过 / 经历过

这里是 现在完成时：

has + faced

face 不只是“脸”，作动词时很常见：

face problems = 面对问题
face difficulties = 面临困难
face criticism = 面临批评
face controversy = 面临争议

⭐ his share of controversies

这是这句话最值得学习的地方。

his share of controversies

字面上：他所占的一份争议

但实际意思是：

他也经历过不少争议

所以：

have / face one's share of + 名词

经常表示：

某人也没少经历……

例如：

He has faced his share of problems.
他也没少遇到问题。

She has faced her share of criticism.
她也没少受到批评。

We've faced our share of challenges.
我们也经历过不少挑战。

📌 整句结构

Tom + has faced + his share of controversies

Tom → 主语
has faced → 经历过 / 面对过
his share of controversies → 不少争议

所以以后看到：

someone has faced his/her/their share of + 名词

可以直接理解成：

“某人也没少经历……” 👍
