答案解析
正确答案:A
解析:
这道题考查的是**特殊疑问句的结构**以及**主语疑问句**的用法。
### 正确答案:A
### 详细解析:
1. **判断疑问词的角色**:
在英语的特殊疑问句中,我们需要首先判断疑问词(Who, What, Which等)在句子中充当什么成分:
* **如果疑问词作主语**:语序不需要倒装,直接采用“疑问词 + 谓语动词 + 其他”的结构,且**不需要**添加助动词(do/does/did)。
* **如果疑问词作宾语或状语**:语序需要倒装,即“疑问词 + 助动词/be动词 + 主语 + 谓语...”,此时**需要**添加助动词。
2. **分析本题句子结构**:
* 原句意为:“是谁给了你那些花?”
* 在这个句子中,动作是 "gave"(给),执行这个动作的人(即主语)正是我们要问的 "Who"。
* 因为 **Who 在句中作主语**,所以句子保持陈述语序,直接使用谓语动词的过去式 `gave`,前面**不需要**加助动词 `did` 或 `do`。
3. **排除干扰项**:
* **B. do**:错误。首先时态不对,`gave` 是过去式,助动词应用 `did`;其次,即使时态正确,主语疑问句也不加助动词。
* **C. did**:错误。这是最常见的干扰项。如果加了 `did`,后面的动词必须还原为原形 `give`(即 *Who did give you...* 这种结构通常只用于强调语气,而在常规语法考题中,标准的主语疑问句不加助动词)。由于题目中给出的是 `gave`(过去式),所以不能选 `did`。
### 总结规则:
* **Who gave you the flowers?** (Who作主语,√ 正确)
* **Who did give you the flowers?** (强调句式,一般情况不首选)
* **Who did you give the flowers to?** (Who作宾语,需要助动词did,语序倒装)
因此,本题空格处不需填任何词,故选 **A**。
