2018中考英语：易混淆知识点（5）

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.
