✍️ Ai批改: 好的，我来分析这个英文句子的结构，并将其中的主语、动词和宾语用中文标注出来：

原句：
And so they were, but they did not know HOW happy till the pretty life in the Red Villa was over and done with, and they had to live a very different life indeed.

分句1: And so they were
- 主语 (Subject): they
- 动词 (Verb): were (系动词)
- 表语 (Complement): so (省略了前文提到的形容词，可能是happy)

分句2: but they did not know HOW happy
- 主语 (Subject): they
- 动词 (Verb): did know (动词短语，did为助动词，know为主动词)
- 宾语 (Object): HOW happy (疑问词引导的名词性从句作宾语)

分句3: till the pretty life in the Red Villa was over and done with
- 连词 (Conjunction): till (引导时间状语从句)
- 主语 (Subject): the pretty life in the Red Villa
- 中心词: life
- 修饰语: the pretty (形容词), in the Red Villa (介词短语作后置定语)
- 动词 (Verb): was (系动词)
- 表语 (Complement): over and done with (形容词短语作表语)

分句4: and they had to live a very different life indeed
- 主语 (Subject): they
- 动词 (Verb): had to live (动词短语，had为助动词，live为主动词)
- 宾语 (Object): a very different life indeed
- 中心词: life
- 修饰语: a very different (形容词短语), indeed (副词强调)

中文标注总结：
1. 分句1: 主语“they” + 系动词“were” + 表语“so”（他们确实如此）。
2. 分句2: 主语“they” + 动词“did know” + 宾语“HOW happy”（但他们不知道有多幸福）。
3. 分句3: 时间状语“till” + 主语“the pretty life” + 系动词“was” + 表语“over”（直到红房子的美好生活结束）。
4. 分句4: 主语“they” + 动词“had to live” + 宾语“a very different life”（他们不得不面对截然不同的生活）。

句子逻辑：
通过并列连词“but”和“and”连接，表达转折（原以为幸福，实则未意识到）和结果（生活巨变后的对比）。时间状语“till”说明前文“不知道多幸福”的状态持续到红房子生活结束为止。
