问题选择题

Many a student ________ failed in the biology exam，and Tom is the only one of them who ________ decided to give up the course.

A．have；has　

B．have；have

C．has；have　

D．has；has

答案

答案：B

题目分析：主谓一致。 Many a +单数名词谓语动词用单数，不止一个。Who 引导定语从句，看先行词，如果先行词是one of+ 名数复数，则定语从句谓语动词用复数形式。；如果先行词是the only one of+名词复数，定从的谓语动词则用单数形式。本句话意思为，不止一个学生生物考试不及格，Tom 是唯一一个决定放弃这门课的学生。
