2011北京卷英语21,23,25,27,28,30,31,35详解
21.Experience of this kind (D) in both the U.S.and Europe well before the Second World War.
A.have conducted B.have been conducted
C.had conducted D.had been conducted
因为主语是Experience,所以谓语动词应该用被动,排除A和C,二战是已过去的事,但经验被指挥是在二战之前,所以应该用过去的过去,选D正确.
23.Tom （C） in the library every night over the last three months.
A.works B.worked C.have been working D.had been working
have/has been doing表示过去持续做某事.
25.It’s important for the figures （A) regularly.
A.to be updated B.to have been updated C.to update D.to have uodated
固定搭配,it's important for sb to do sth,这里的主语是figures,to do这里是不定式,所以用不定式的被动,选A.
27.—That must have been a long trip.
—Yeah,it (C) us a whole week to get there.
A.takes B.has taken C.took D.was taking
问句,对过去表示肯定的推测,答句应该是对过去事实的描述,应用过去时.
28.—Where are the children?The dinner’s going to be complerely ruined.

A.weren’t B.hadn’t been C.wouldn’t be D.wouldn’t have been

虚拟语气,固定搭配 if I +过去式,I would……

A.by B.for C.with D.in
固定短语：take for color 把……着色

21.D experiment与conduct之间是被动关系，故不选AC，before the second world war 是过去的过去 ，故用过去完成时。
23.C 考察时态，题干中出现明显的over the last three months，用于现在完成进行时或现在完成时。
25.figure与update之间是被动关系，故不用CD,regularly表示一般情况，所以选A
27.C 题干中must have done是对过去的肯定推测，因此提示时间在过去，选择一般过去时。
28.A考察虚拟，题干中出现always，从句虚拟使用一般过去时
