205. The young girl sitting next to me on the plane was very nervous. She ____ before. A. hasn‘t flown B. didn‘t flyC. hadn‘t flown D. wasn‘t flying 题干中前半句“was”，一般过去时；后半句最后出现“before”说明是在过去（was）之过去，前半句的“was”给出了选择过去完成时的时间背景，因此选择C. 206. By the time you get back， great changes ______ in this area.A.will take place B.will be taken place C.are going to take place D.will have taken place 题干“By the time you get back”，是“到你（将来）回来时”，这里因为是时间状语从句，将来时用一般时代替，因此后半句的时间应当使“将已经”，故选择D. 207.When their first child was born, they ______ for three years. A. had married B. had been married C. had got married D. got married [解析★]选B。这道题考察过去完成时。看到for three years, 第一，马上想到使用完成时，排除Ｄ。第二，动作必须是可延续性的，所以排除Ａ、Ｃ两项。答案Ｃ。208.I was really anxious about you. You _____ home without a word. A. mustn’t leave B. shouldn’t have left C. couldn’t have left D. needn’t leave [解析★★]选B。 这道题情态动词+have done 表示“对过去发生的事件的推测”。shouldn’t have done 表示“本不该做某事，但是却做了。”所以选B最合适。C. couldn’t have done 表示“过去不可能发生的事”。 209. When all the work ______, you may go back home. A. finishes B. has finished C. is finished D. will be finished[解析]选C。考察两个语法点：第一考察主将从现，主句使用may + 动词原形，相当于一般讲来时，从句应该使用一般现在时，所以A、C两项入围。第二考察被动语态。Work 和finish 的关系是动宾关系，因work（工作）自己本身不能发出finish这个动作。所以用被动语态。答案是C 210.Lucy and I are classmates. We _______ in Class One. A. all are B. are all C. both are D. are both【解析】此题容易误选A或C。这里受到汉语思维的影响引起的，译成汉语正好是“我们都在一班”。表示两者都要用both，both一般放在be动词、情态动词或助动词之后，行为动词之前。正确答案为D。 (责任编辑：admin) |
