1.Don't discuss the problems with your partne unless you (B) to do so.A.ask B.are asked C.will ask D.will be asked unless 引导的条件状语从句 要用主将从现 所以选B 一般现在时 2.I(D) to get there before seven tomorrow.so I'll have to get up arly.A.told B.have told C.will tell D.was told 一般过去时的被动语态 was/were +done 我被告知要在明天七点前到达那里 所以我得起早了 3.If the question(C) incorrectly,() question will be given to you.A.is answered;other B.answers;other C.is answered;another D.answers;another 首先可以判断是被动语态 因为 question 是物 不能自己发出回答吧 ..排除BD other是指很多个体中一个怎样 泛指别的 其他的 another是一个怎样 指另一个 文中特指 另一个问题 所以用 anthor 4.--Lookat the sign on the right.----Oh,parking(B) here.A.doesn't allowed B.isn't allowed C.didn't allow D.wasn't allowed 由上句可知 应该用一般现在时的被动语态 表示经常性的动作 is/am/are+done 5.--Do yoy believe there are aliens?----I'm afraid not.I don't think aliens(B) in space.A.can find B.can be found C.can be found D.can;t be found 考察带情态动词的被动语态 can + be + done ——你相信这里有外星人吗 ——我恐怕不信 我认为外星人在宇宙空间中不能被发现 D.的话就是双重否定..就不对了 think的宾语从句应该否定前移 把从句中的not 转移到think前变成don't 6.--Mum,can I go skating now?----Well,you may go after your homework(C).A.has finished B.will finish C.is finished D.was finished 这个和第一题有点像 after引导时间状语从句 表示主句动作发生在从句动作之后 用一般现在时
