答案：二、3. C

解析：

【分析】
拿到题目首先明确核心信息：问句用How long提问，时态为现在完成时has stayed，是对从过去延续到现在的状态的总时长进行提问，我们需要选出能对应表示「从过去某一时间点起始、延续至今」的引导词。接下来逐个排查选项：首先排除B，When引导的是瞬间时间点，无法回答时长类问题；再排除D，Before意为“在…之前”，代入后语义逻辑矛盾，不可能是来中国之前就待在南通；再排除A，Until表示动作截止的时间点，代入后语义和问句语境不匹配；只有C选项Since表示“自从”，后接一般过去时的从句，刚好符合现在完成时对持续时长的回答要求。
【解析】
1. 先明确问句特征：How long针对持续时长提问，搭配现在完成时，答语需要给出状态延续的时间起点。
2. 逐一辨析选项：
选项A：Until意为“直到……为止”，强调动作的截止时间，代入后语义不符合语境，排除；
选项B：When意为“当……的时候”，仅能引导瞬间时间状语，无法回应时长类提问，排除；
选项C：Since意为“自从……以来”，后接一般过去时的从句，是现在完成时的标志性时间状语，用法和语义完全匹配题干要求；
选项D：Before意为“在……之前”，代入后逻辑矛盾，不符合常理，排除。
综上正确选项为C。
【答案】
C
【知识点】
现在完成时，since的用法，how long问答
【点评】
本题是现在完成时模块的基础常考题，易错点是容易误选A选项until，解题时要结合问句时态和语义双重判断，牢记since加过去时间点/一般过去时从句，是现在完成时回答时长提问的典型结构。

playing the piano. She's really talented in the arts.

答案：二、4. B

5. — What do you think is

a happy family?
— I believe love and understanding are the most important things.

A.at the end of
B.at the heart of
C.at the top of
D.at the back of

答案：二、5. B

解析：

【分析】
首先我们可以从答句获取关键提示：答句提到“爱和理解是最重要的要素”，说明问句的表意是“你认为什么是幸福家庭的核心？”。接下来只需要逐一辨析四个选项的介词短语含义，找到和“最重要、核心”语义匹配的短语，就能选出正确答案。
【解析】
我们逐一分析每个选项：
1. 选项A：at the end of 含义为“在……的末尾/尽头”，代入句子语义完全不通，排除。
2. 选项B：at the heart of 含义为“位于……的核心，是……的核心”，代入问句后句意为“你认为什么是幸福家庭的核心？”，和答句提到的“爱与理解是最重要的事物”形成完美呼应，符合语境。
3. 选项C：at the top of 含义为“在……的顶部，位列……之首”，通常用来描述位置、排名靠前，不能用来表达事物的核心本质，不符合语境，排除。
4. 选项D：at the back of 含义为“在……的后方；支持”，代入句中语义逻辑不通，排除。
因此正确答案是B。
【答案】
B
【知识点】
介词短语辨析，固定搭配
【点评】
本题考查常见介词固定短语的语义辨析，解题的突破口是抓住答句给出的“the most important things”的提示，反向推导问句缺失的表意，平时学习中要注意多积累由不同介词和名词构成的常用固定短语的含义和适用场景。
