A
因為是從句,是陳述句啊,B是一個疑問句
could是can的客氣說法.
-could you tell me () at that time?-I was Watching TV at home.
-could you tell me () at that time?-I was Watching TV at home.
-could you tell me () at that time?
-I was Watching TV at home.
A.what you were doing
B.what were you doing
C.what are you doing
D.what you are doing
為什么不是B啊..【could在這里不是過去時了麼,為什么問句中可以出現(xiàn)兩個過去時的單詞?】
-could you tell me () at that time?
-I was Watching TV at home.
A.what you were doing
B.what were you doing
C.what are you doing

為什么不是B啊..【could在這里不是過去時了麼,為什么問句中可以出現(xiàn)兩個過去時的單詞?】
