句式变换
含情态动词的疑问句、否定句的变化均需 借助于情态动词完成。 1. 一般疑问句：直接将被动语态的陈述句 中的情态动词提前。 Must this task be finished at once? 这项任务必须立即完成吗？
注意：含情态动词的被动语态的一般疑问句 的回答，应保留原情态动词，但must表“必 须”时，其否定回答应用needn’t；need表 “必要”时，其肯定回答应用must。如： --- Must my exercise book be handed in now? 我的练习本必须现在上交吗？ --- Yes, it must. 是的，必须现在上交。 （No, it needn’t. 不，不必现在上交。） --- Need he be operated on at once? 他必须立即手术吗？ --- Yes, he must. 是的，他必须。 （No, he needn't. 不，他不必。）
Look at these sentences.
I think students should bห้องสมุดไป่ตู้ allowed to do homework with friends.
Sixteen-year-olds should not be allowed to drive.
Do you think sixteen-year-olds should be allowed to choose their own clothes?

否定句: 主语+情态动词+not+ be+动词过去分词.
疑问句: 情态动词+ 主语+ be+ 动词过去分词?

4. 反意疑问句：借助情态动词构成附加疑问 部分。如： This bridge can be built next year, can't it? 这座桥明年能建成，是吗？
Teenagers should be allowed to choose their own clothes. 应该允许青少年选择他们自己的服装。 Students should not be allowed to have parttime jobs. 不应该允许学生们做兼职工作。 Can these books be taken out of the reading room? 可以把这些书带出阅览室吗？ When must the work be finished? 这些工作必须什么时候完成？

2. 特殊疑问句 ：由特殊疑问词加上被动语态 的一般疑问句构成。 When must this task be finished? 这项任务必须在什么时候完成？ 3. 否定句： 在情态动词后面加上not或never 即可，但must表"必要"时否定式为needn't。 This task needn't be finished at once. 这项任务没必要立即完成。
