B
翻譯：他第一次來(lái)到中國(guó)就參觀了上海.
the first time
用來(lái)引導(dǎo)時(shí)間狀語(yǔ)從句,意思是：當(dāng)?shù)谝淮?..時(shí)候.
比如：
1）I knew we would be good friends the first time I met her．
第一次見(jiàn)到她,我就知道我們會(huì)成為好朋友.
2）This is the first time I have been to the Great Wall．
這是我第一次去長(zhǎng)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.
我記得上次我們見(jiàn)面的時(shí)候總是我在說(shuō)話,這一次我要讓你說(shuō)話.
補(bǔ)充：the first time 相當(dāng)于一個(gè)連詞（=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：在第一時(shí)間,第一次,是一個(gè)介詞短語(yǔ),沒(méi)有連詞是功能,一般位于句末,比如：I must know the matter at the first time.我希望第一時(shí)間知道這件事.所以D答案排除.
在“The first time Venus played in a big event was in 1996.”這個(gè)句子中,the first time 指第一次,是在句首,不是連詞,而是表示時(shí)間的名詞,關(guān)系代詞when可以省略.
