题目

He visited Shangha_______he went to China. A.at the first time B.the first time C. the first time w
He visited Shangha_______he went to China.
A.at the first time B.the first time C. the first time when D. at the first time when
我知道the first time 可作连词，但它也可作时间状语，选CD 难道不可把它看作定语从句么？
问题补充：还是很疑惑，高一英语UMIT2中The first time Venus played in a big event was in 1996.教参把 the first time解释成先行词，省略了when，以此类推CD不也是对的了吗？

答案

B
翻译：他第一次来到中国就参观了上海.
the first time
用来引导时间状语从句,意思是：当第一次...时候.
比如：
1）I knew we would be good friends the first time I met her．
第一次见到她,我就知道我们会成为好朋友.
2）This is the first time I have been to the Great Wall．
这是我第一次去长城.
3）I remember that the last time we met I did most of the talking,so perhaps I should let you do the talking this time.
我记得上次我们见面的时候总是我在说话,这一次我要让你说话.
补充：the first time 相当于一个连词（=when + first）,后面接句子.所以when是多余的,排除C答案.at the first time 表示：在第一时间,第一次,是一个介词短语,没有连词是功能,一般位于句末,比如：I must know the matter at the first time.我希望第一时间知道这件事.所以D答案排除.
在“The first time Venus played in a big event was in 1996.”这个句子中,the first time 指第一次,是在句首,不是连词,而是表示时间的名词,关系代词when可以省略.
