America is a country ________many different nationalities as well as one with foreign immigrants _______ the majority of its population.

A．consisting of; making up	B．made up of; consisting of
C．consisted of; making up	D．making up of; occupied with

答案

A

解析

试题分析：考查现在分词做定语和with复合结构：句意：美国是一个由许多不同名族构成的国家，也是移民人口构成了它的主要人口的国家。第一空填consisting of，做定语，因为consist of是不及物动词短语，没有被动，或者填made up of，因为make up是及物动词短语，被动是be made up of，用过去分词做定语，第二空是with复合结构，因为foreign immigrants和make up（组成）指主动关系，选A。
