中考英语常考易混淆的知识点(五)
201.Jack’s father asked him, “Have you packed your things?” (改为间接引语)
Jack’s father asked him ______ he ______ packed his things.
if, had。将一般疑问句的直接引语改为间接引语，就是将其改为一个以if(是否)引导的宾语从句。宾语从句要用陈述句语序，主句中的谓语动词是过去式时，宾语从句的谓语动词也用过去式。
202.Hurry up, or you’ll miss the early bus. (改为含条件状语从句的复合句)
______ ______ hurry, ______ ______miss the early train.
If you, you will。“祈使句+and / or+陈述句”句型中的祈使句就相当于一个if引导的条件状语从句。注意：改写时因为前面用了连词if，后面的连词and / or要去掉。
203.This text is very difficult. I can’t understand it. (合并为同义句)
This text is ______ difficult for me ______ understand.
too, to。因为too…to…意为“太……而不能……”正好与前面的意思相吻合。另外，改写后的句子也可说成The text is so difficult that I can’t understand it.
204.I know a little bit about Italy as my wife and I ____ there several years ago.
A. are going B. had beenC. wentD. have been
题干中前半句“know”，一般现在时;后半句出现“several years ago”，明显的表示过去的时间，所以选择一般过去时“went”，答案C.本题很多同学都顺着中文“去过”而误选了“D. have been”，是没有掌握好语句中出现了具体过去时间这一关键。
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。
211.If there are ______ trees,the air in our city will be _______cleaner.(more/fewer/much)
横线后trees是可数名词的复数形式，只能在修饰名词的复数的fewer和more中选择，根据句意选择“更多more”;而后面cleaner往往学生会以为是个不可数名词而选择much，其实后面是clean个形容词，而且其后er表示它是形容词的比较级，只有much才能修饰形容词的比较级。
212.What does the word “alone” mean?=What’s the ___________ __________ the world “alone”?
上句中mean作动词，下句中meaning作名词，固定搭配：“the meaning of……的意思”，学生容易想到meaning，而忽视了后面的介词的搭配，容易写成：off/for
Study hard and your dream ______
