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__________.学生看到了” and”会以为是前后动词时态对照，会写 come true/ comes true，选 will come true，是因为它是以下句子的缩略： If you study hard, your dream will come true
When Martin visited Beijing for the first time, he__________ the city.大多数学生容易写成： was falling in love with/ falling in love with分析：句中有 when还有暗示 visited，学生很容易联想到第三单元的从句，而选择上面的答案。 fell in love with“爱上”，是暂时性动词，应该选用一般过去时。
