這個(gè) 選 D 這跟虛擬語氣沒半點(diǎn)聯(lián)系 希望樓上的朋友不要亂說
為幫助理解 可以看成是一個(gè)對(duì)話
A:I didn't know you were in London.how long have you been here?
B：.
這里用過去時(shí)是因?yàn)?在A 說話之前 A 不知道B 去了倫敦 是在這個(gè)動(dòng)作之前
有一個(gè)時(shí)間點(diǎn)
這屬于 口語交際中 的簡(jiǎn)單語法問題
I ___ you____ in London .how long have you been here?
I ___ you____ in London .how long have you been here?
A don't know ,were
B hadn't known ,are
C havn't known ,are
D didn't know ,were
這類題總是做錯(cuò)
A don't know ,were
B hadn't known ,are
C havn't known ,are
D didn't know ,were
這類題總是做錯(cuò)
