Question

The research group ____________ 15 members has made great achievements in recent years.

A．is made up of

B．makes up

C．made up of

D．making up of

Answer 1

C

试题分析：考察定语用法。本题的关键是分清句中结构，本句的谓语动词是has made great achievements in recent years.前面的形容词短语made up of 15 members是对名词The research group进行修饰限制。相当于which is made up of 15 members.句意：由15个成员组成的研究队伍，在最近几年里已经取得了巨大的成就。故C正确。
点评：本句中的短语be made up of…由…组成；可以使用形容词短语made up of 15 members修饰前面的名词，相当于定语从句。在具体的使用中要主语这两者的互换。
