He could speak English fluently because he __________ it for four years when he was a college student. A．had studied B．have been studying C．studied D．was studying

Answer 1

C

试题分析：考查时态：句意：他的英语可以说的很流利，因为他做大学生的时候学习了四年。说明学习英语是在大学当学生的时候，用过去时。选C。 点评：时态的考查要根据本句的关键词，本题的关键词是when he was a college student.     本题特别容易错选B项。但学习的动作发生在过去已结束。只能用过去时。
