A new study shows older men          a lack of deep sleep are nearly twice as likely to develop high blood pressure.

A．suffering for

B．who is suffering

C．who suffer from

D．who suffer to

答案

C

解析

现在分词、定语从句都可作定语但是“遭受…”要用suffer或者suffer from;所以排除A、D两个选项，B选项who is suffering 中的who指的是men要用动词are，所以只能选C who suffer from相当于分词suffering from的作用。
