A terrible accident____,however,occur the other day and we
A terrible accident _______,however,occur the other day and we witnessed it _______ accident.
A.does;by
B.did;by
C.has to;on
D.had to;on
我知道答案选B,我想问的是前面一个空为什么不能用had to?（我单独问前面一个空,和后面的by accident 无关）
A terrible accident _______,however,occur the other day and we witnessed it _______ accident.
A.does;by
B.did;by
C.has to;on
D.had to;on
我知道答案选B,我想问的是前面一个空为什么不能用had to?（我单独问前面一个空,和后面的by accident 无关）
B是对的.had to表示不得不,难道你认为这事故是必然发生的吗?
再问： 那能不能把to去掉只用had
再答： had也不行，你想用完成时，occur要加ed, 语法不对。the other day是前几天的意思，与过去时连用。 你学习进步，更上一层楼！ (*^__^*) 不明白的再问哟，请及时采纳，多谢！
