【经典例题】Many workers built this factory in 2001. This factory ___ ____ by many workers in 2001.
【名师精解】本题的正确答案为：was built.正确解题的关键是被动语态的构成(built――be built)和过去时态(be动词要用was，与原句的built对应)。
2. 直接引语与间接引语的转换
【经典例题】He asked me,"Where are you going?"
He asked me____ ____ ____ ____.
【名师精解】本题的正确答案为：where I was going.在本题中需要注意的是人称的变化(you——I)和特殊疑问句中语序(are you——I was)的变化，考生要兼顾，避免因顾此失彼造成的失分。
3.There be句型的变换

【名师精解】正确答案是：5. 20 years ago 6.until. 前一道小题考查的是“20年前”的表达方式，用完成时和过去时两种不同的时态表达同一个意思。后一道小题考查的是时间的常用表达方式，考查 not until 句型的用法。
6.词或词组间的互换
【经典例题】He spent 20 dollars buying this book. He____20 dollars_____ this book.
【经典例题】She does well in English. She is ___ ____ ____English.

7.句子与词组间的互换
【经典例题】We're always busy with our work. We seldom have____ _____ .
【经典例题】The boy is very young. The boy can't understand it. The boy is___ young ____understand it.

【名师精解】这两道小题的正确答案是：less interesting than 和.faster than.这两道小题考查的都是表达比较意义的句型之间的转换。考生在复习时，不应该拘泥于两个句型之间的转换，而应努力做到灵活掌握、触类旁通，把各个句型的用法特点弄清楚，这样无论什么样的转换都不会困难。
10. 词形的派生
【经典例题】The teacher told us to be careful when we did our exam. The teacher told us to do our exam.________
【名师精解】本题的正确答案是：carefully.如果考生对carefully这个词较为熟悉，这道题就不会有任何困难，如果考生不熟悉carefully这个词，根据构词法也可轻松解出。考生只要掌握了形容词变相应副词的一般情况，就不难得出正确答案。
11. 从句的变换(1)主从复合句与并列句的相互转换
【经典例题】Hurry or you will be late for school. _____you don't hurry, you will be late for school.(2) 从句与从句的相互转换

12. 用连接词合并两个简单句
【经典例题】Jane couldn't sing well. I couldn't sing well, either. _____Jane _____I could sing well.
【名师精解】本题的正确答案是：Neither……nor……。它的意义是：“两者都不”，同时也要注意用了这一表达方式以后，后面要用肯定式(could)。同时应该注意它和both……and, neither……nor的区别。
