A．do; doing B．doing; do C．done; done D．do; done 解析：注意人与物所对应动词的不同用法。D项符合题意。 答案：D 三、语法重点 本单元主要学习情态动词ough to，have to/dont have to，mustnt和neednt的用法。请做下列试题。 可能这样考 ①—Has Mary finished writing her article? —No，and it ________ before class was over. A．should be finished B．should finish C．should have finished D．ought to have been finished 解析：ought to/should have done本应该做某事，而实际上没做，含有责备的意味。it指的是article，和finish之间是被动关系，所以用D项。 答案：D ②—James didnt turn up last night，did he? —No.He ________.We had changed our plan. A．shouldnt have come B．neednt have come C．didnt need to come D．neednt come 解析：shouldnt have come“本不应该来而实际来了”；neednt have come“本没有必要来而实际来了”；didnt need to come“没有必要来，实际上也没来”，need用作了实义动词；neednt come“不必来”，表将来。而A、B两项与句意矛盾。 答案：C ③As it turned out to be a small house party，we ________ so formally. A．neednt dress up B．did not need have dressed up C．did not need to dress up D．neednt have dressed up 解析：由“As it turned out...”的时态可知，事情发生在过去，所以用neednt have dressed up“本没必要打扮，而事实已经打扮了”，表示与过去事实相反的假设。 答案：D ④You ________ practise the drums while the baby is sleeping. A．neednt B．mightnt C．mustnt D．wont 解析：句意：婴儿睡觉的时候你一定不要练习打鼓。mustnt在此意为“不要，禁止”。 答案：C ⑤—Must I return this magazine within one week? —No，you ________.
