When the old man was alive,he _ sit for hours at the door.would B.could C.must D.might
答案 :D
A.would 是will 过去式 表示"将" 在这里 一定不对
B.could 是 can 过去式 表示“能” 也不正确
C.must 翻译为一定 也不对
D.might 是 may 的过去式 表示 “可能” 当这个老男人活着的时候,他“可能”坐在门口数个小时了.故选择D.
I hope to help you 文落write.

When the old man was alive, he could sit for hours at the door.
答案:B. could

B. could
意思上could “能”符合句意。另,前面was alive 过去式,所以用could。
