英语还原句子的技巧主要针对特殊句式（如疑问句、强调句、倒装句等），通过调整语序恢复为基本陈述句结构。以下是具体方法及示例：

一、常见特殊句式的还原方法

疑问句还原

将疑问句调整为陈述句语序。例如：

- 疑问句：Is this the train for Glasgow？

还原后：This is the train for Glasgow.

- 疑问句：Did she call you last night？

还原后：She called you last night.

强调句还原

将强调句转换为普通陈述句。例如：

- 强调句：It was because he loved my money that he married me.

还原后：Because he loved my money, he married me.

- 强调句：This is the factory which/that you visited yesterday.

还原后：This is the factory you visited yesterday.

倒装句还原

将倒装句调整为正常语序。例如：

- 倒装句：So fast does light travel that we can hardly imagine its speed.

还原后：Light travels so fast that we can hardly imagine its speed.

- 倒装句：Never have I seen such a beautiful sunset.

还原后：I have never seen such a beautiful sunset.

二、还原句的注意事项

主谓一致

还原后需检查主谓是否一致。例如：

- 原句：The company, which has been expanding rapidly, hired 50 new employees.

还原后：The company hired 50 new employees, which has been expanding rapidly.

时态与语态

需确保时态和语态正确。例如：

- 原句：He was reading a book when the phone rang.

还原后：He was reading a book when the phone rang.

标点符号

还原后注意标点符号的使用。例如：

- 原句：This is the man, whose car is parked outside.

还原后：This is the man whose car is parked outside.

三、实战练习建议

专项练习

通过教材或试卷中的专项练习题巩固方法，如：

- 将以下疑问句还原为陈述句：

a. What time did you call last night？

b. Where did she find the lost key？

- 将以下强调句还原为普通句：

a. It is the movie that inspired us.

b. The project which was completed on time.

错误分析

做完练习后，分析错误原因，如：

- 时态混乱（如将过去完成时误用为过去时）

- 语序错误（如将"whose"提前至错误位置）

- 忽略标点符号变化（如问号未改为句号）

通过以上方法与练习，可有效提升英语句子还原能力，增强写作与阅读的准确性。
