She was born in the year _____ the Second World War broke out.

She was born in the year ______ the Second World War broke out.

A.on which B.when C.about which at

句子的意思是: 她是在第二次世界大战发作的那一年出生的.

全句列出了两个句子,要你选一个词把那两个句子连成一个复合句.A,C,D三个都不适宜,因为前面的一个名词是 year ,要你申明是什么样的"年",当然只要选用可以申明时间的 B.when 来保持,使后面一句 the Second World War broke out.成为一个定语从句,来润色 year(年).

B.

意思是“他出生在二战发作的那一年。” when 引导的定语从句润色 the year.
