Ⅳ. 请将两个句子合并成一个含有宾语从句的复合句。
1. The little girl asked her mum. Where do rainbows come from?

2. Could you tell me? Where can I find a post office near here?

3. He doesn't know. How old is Mary?

4. Our teacher told us. Light travels much faster than sound.

1. The little girl asked her mum where rainbows come from.
2. Could you tell me where I can find a post office near here?
3. He doesn't know how old Mary is.
4. Our teacher told us that light travels much faster than sound.

【分析】
合并两个句子为宾语从句需遵循三个核心规则：①引导词：原句是特殊疑问句时，用对应的疑问词（如where、how old等）；②语序：必须改为陈述语序（主语在前，谓语在后），不能用疑问语序；③时态：若主句是一般过去时，从句需对应过去时态，但从句是客观真理（如科学事实）时，用一般现在时；第4题还可加that引导宾语从句（也可省略）。逐个处理：
1. 主句是一般过去时的The little girl asked her mum，原特殊疑问句引导词用where，将疑问语序改为陈述语序（rainbows come from）后合并；
2. 主句是委婉语气的Could you tell me（could不影响时态），原特殊疑问句引导词用where，将疑问语序改为陈述语序（I can find）后合并；
3. 主句是一般现在时的He doesn't know，原特殊疑问句引导词用how old，将疑问语序改为陈述语序（Mary is）后合并；
4. 主句是一般过去时的Our teacher told us，从句是客观真理，时态用一般现在时，加that引导后合并。
【解析】
1. 主句为The little girl asked her mum，原特殊疑问句的引导词用where，将疑问语序“do rainbows come from”改为陈述语序“rainbows come from”，合并得：The little girl asked her mum where rainbows come from.
2. 主句为Could you tell me，原特殊疑问句的引导词用where，将疑问语序“can I find”改为陈述语序“I can find”，合并得：Could you tell me where I can find a post office near here?
3. 主句为He doesn't know，原特殊疑问句的引导词用how old，将疑问语序“is Mary”改为陈述语序“Mary is”，合并得：He doesn't know how old Mary is.
4. 主句为Our teacher told us，从句是客观真理，时态保持一般现在时，加that引导宾语从句，合并得：Our teacher told us that light travels much faster than sound.
【答案】
1. The little girl asked her mum where rainbows come from.
2. Could you tell me where I can find a post office near here?
3. He doesn't know how old Mary is.
4. Our teacher told us that light travels much faster than sound.

【解析】
1. 选D。根据下文“Elephants never forget”（大象从不忘记），可知此处指大象有良好的记忆力，符合语境。
2. 选B。下文内容围绕大象耳朵的功能展开，故小标题对应“Ears”，符合逻辑。

6. 选C。小标题为“Growing tusks（生长的象牙）”，可知大象的象牙从不停止生长，符合主题。
7. 选C。前文说明象牙不停生长，因此象牙越长，大象年龄越大，为因果关系，用“so”连接。
8. 选C。前文提到非洲雌雄象都长象牙，此处转折说明只有雄性亚洲象能生长象牙，“grow”符合语境。
9. 选A。根据小标题“Elephants never forget”，可知大象能长时间记住其他大象，“remember”贴合主题。
