题目解答
答案
1. Please come and join us.
解析：将 "Will you please come and join us?" 改为祈使句，只需将 "please" 提前即可，表示请求对方加入。
2. Don't be late again.
解析：将 "You should not be late again." 改为祈使句，使用 "don't" 加上原形动词 "be"，表示禁止或建议不要做某事。
3. Don't answer the phone while driving.
解析：将 "You should not answer the phone while driving." 改为祈使句，同样使用 "don't" 加上原形动词 "answer"，表示在驾驶时不要接电话。
4. Sit up straight, children. Don't slouch over the table.
解析：将 "You should sit up straight, children. You can't slouch over the table." 改为祈使句，使用 "sit up straight" 表示坐直，"don't slouch" 表示不要无精打采地趴在桌子上。
5. Be careful and put those things back in their places.
解析：将 "You need to be careful and put those things back in their places." 改为祈使句，使用 "be careful" 表示要小心，"put those things back in their places" 表示将物品放回原位。
祈使句通常用于表达命令、请求、建议或警告等，其结构通常是动词原形开头，有时可以加上主语 "you"（在正式文体中通常省略）。表示否定的祈使句则在动词原形前加上 "don't"。
解析
祈使句用于表达命令、请求、建议或警告，通常以动词原形开头。
- 肯定句：直接使用动词原形，如 "Sit down."
- 否定句：在动词前加 "don't"，如 "Don't talk."
- 含 "please" 的请求句：将 "please" 放在句首，如 "Please help me."
本题需将原句中的 "should" "can't" "need to" 等结构转换为祈使句形式。
1. Will you please come and join us?
关键点：原句含 "please"，直接提取 "please" 放句首，省略 "will you"。
转换：
Will you please come... → Please come...
2. You should not be late again.
关键点：原句含 "should not"，否定祈使句用 "don't + 动词原形"。
转换：
You should not be → Don't be
3. You should not answer the phone while driving.
关键点：同第2题，"should not" → "don't"，保持状语从句位置。
转换：
You should not answer → Don't answer
4. You should sit up straight, children. You can't slouch over the table.
关键点：
- 第一句 "should" → 动词原形 "sit"
- 第二句 "can't" → 否定祈使句 "don't slouch"
转换：
You should sit up straight→Sit up straight
You can't slouch→Don't slouch
5. You need to be careful and put those things back in their places.
关键点：原句 "need to" 省略，直接用动词原形开头。
转换：
You need to be careful → Be careful
