题目解答
答案
本题考察条件句中“可能性小的假设”用法：
- A项“If I were you...”为与现在事实不符的假设，符合要求。
- B项为真实条件句，表将来可能情况，不符合。
- C项“If he had studied...”为与过去事实相反的假设，符合要求。
- D项为真实条件句，表将来可能，不符合。
答案：A. If I were you, I would apologize.
C. If he had studied harder, he would have passed the exam.
解析
本题考查虚拟语气在条件句中的用法，核心在于区分可能性小的假设与真实条件句。
- 可能性小的假设通常使用第二类虚拟条件句（与现在事实相反）和第三类虚拟条件句（与过去事实相反）。
- 真实条件句（第一类）描述可能发生的情况，可能性较大。
关键点：通过条件句的结构（if从句的动词形式）判断假设是否虚拟。
选项分析
A. If I were you, I would apologize.
- 结构：if从句用were（过去时，与现在事实相反）。
- 类型：第二类虚拟条件句，表示不可能实现的建议。
- 结论：符合“可能性小的假设”。
B. If it rains tomorrow, we will cancel the trip.
- 结构：if从句用rains（现在时），主句用will cancel（将来时）。
- 类型：第一类真实条件句，描述可能发生的情况（下雨是有可能的）。
- 结论：不符合要求。
C. If he had studied harder, he would have passed the exam.
- 结构：if从句用had studied（过去完成时），主句用would have passed（虚拟完成时）。
- 类型：第三类虚拟条件句，表示与过去事实相反的假设（已考试结束，无法改变）。
- 结论：符合“可能性小的假设”。
D. If I have time, I will visit you.
- 结构：if从句用have time（现在时），主句用will visit（将来时）。
- 类型：第一类真实条件句，描述可能实现的计划（有时间是有可能的）。
- 结论：不符合要求。
