四、非延續(xù)性動詞與延續(xù)性動詞的相互轉(zhuǎn)換

即非延續(xù)性動詞與延續(xù)性動詞進(jìn)行轉(zhuǎn)換，此時往往會涉及時態(tài)的變化。如：

1. The manager left two hours ago.

  The manager _______ _______ _______ for two hours.

分析：答案為 has been away。leave為非延續(xù)性動詞，不能與for two hours 這樣的一段時間連用，而改成 be away這樣的延續(xù)性動詞后，則連用一般時間。

2. The film began five minutes ago.

The film has been _______ _______ five minutes.

分析：答案為on for。 has been提示時態(tài)是現(xiàn)在完成時態(tài)，“for+時間段”表示“持續(xù)(一段時間)”，常用在含有現(xiàn)在完成時態(tài)的句子里。

3. Mr Li joined the Party twenty years ago.

Mr Li _______ _______ _______ the Party for twenty years.

答案：has been in。短暫動詞join，意為“參加，加入(組織，政黨)”，不能與延續(xù)時間狀語連用，與延續(xù)性時間狀語連用時，將join 改成be in 或be a member in…。

五、運(yùn)用不同引語進(jìn)行轉(zhuǎn)換

即將直接引語變?yōu)殚g接引語或?qū)㈤g接引語轉(zhuǎn)換成直接引語。此時還要注意相關(guān)時態(tài)、人稱、動詞、狀語等的相應(yīng)變化。如：

1. “I’ve found my wallet,” he said to me.

He ______ me that he ______ ______ his wallet.

    分析：答案為told, had, found。此題為將直接引語轉(zhuǎn)換成間接引語。

2. “Did you see her last week?” he said.

He ______ ______ I had seen her the week _______.

    分析：答案為asked, if / whether, before。此題是將疑問句的直接引語轉(zhuǎn)換成間接引語。

3. He asked me where I had been these days.

“Where ______ ______ ______ these days?” he asked.

分析：答案為have, you, been。此題是將間接引語轉(zhuǎn)換成直接引語。

六、運(yùn)用簡單句與復(fù)合句之間的轉(zhuǎn)換

即將簡單句變成同義的復(fù)合句或?qū)��?fù)合句變成同義的簡單句。如：

1. We didn't go out for a walk because it was raining.

We didn't go out for a walk _______ _______ the rain.

分析：答案為because of。將原因狀語從句because it was raining改為表示原因的介詞短語 because of the rain。

2. He was so excited that he couldn't go to sleep.

He was _______ _______ _______ go to sleep.

分析：答案為too excited to。將so…that…換成too…to…結(jié)構(gòu)，原句的that從句為結(jié)果狀語從句，改寫句中的不定式仍表結(jié)果。

3. Now I will show you how to do the work.

Now I will show you ______ _______ _______ do the work.

分析：答案為how you can。即將原句中的“疑問詞+不定式”結(jié)構(gòu)轉(zhuǎn)換成賓語從句。

4. You should put them back after you use them.

You should put them back _______ _______ them.

分析：答案為after using。即將after引導(dǎo)的狀語從句改寫為after引導(dǎo)的介詞短語。

5. She seems to be worried now.

_______ _______ that she _______worried now.

分析：答案為It, seems, is。復(fù)合句 It seems / seemed that sb…與簡單句sb. seems / seemed to …同義，均表示“某人看起來……”。
