The number of people who ____English as a foreign language __more than 750 million. A．learns; is B．learn; are C．learns; are D．learn; is

Answer 1

D

试题分析：句意：学英语作为一门外语的人的数量现在已经超过7.5亿人。Who引导的是定语从句，它在从句中作主语，先行词是people，当who在从句中作主语时，谓语动词的单复数根据先行词来确定，故排除AC；第二空是整个句子的谓语动词，句子的主语是number，故谓语动词用单数，故选D。 点评：本题难度适中。主谓一致是高中阶段的重要的一项语法项目，它们的各种情况比较多，需要考生牢记它们的用法，这里考生容易误选B。 即学即练：Butter and bread _____ their daily food, but the bread and the butter_____ up now. A. is; is eaten  B. are; have been eaten  C. are; are eaten  D. is; have been eaten 解析：D。句意:前一空的butter and bread表示同一概念，谓语动词用单数形式;后一空是指两种不同食物，故选D项。
