小学英文：条件句挑战练习（10 题）
小学英文：条件句挑战练习（10 题）
第三份是混合挑战：第三条件句的 had + 过去分词配 would have + 过去分词、条件在过去而结果在现在的混合条件句、unless 与 Had I 倒装，最后三题改错要指出 will 误入 if 子句、would 误入 if 子句、主句漏了 have 三处错。
快速答案 第三条件句：if 子句 had + 过去分词，主句 would have + 过去分词；混合条件句条件在过去、结果在现在，主句用 would + 原形；unless 等于 if not，子句仍用现在式；Had I known 等于 If I had known；改错要删去 if 子句的 will 与 would，并补回主句的 have。

03 答案与一句解说
| 题号 | 答案 | 一句解说 |
|---|---|---|
| 1 | would have passed | 第三条件句主句用 would have + 过去分词。 |
| 2 | had left | 与过去事实相反，if 子句用 had + 过去分词。 |
| 3 | hadn’t forgotten | 否定用 hadn’t + 过去分词。 |
| 4 | would feel | 混合条件句：过去的条件，现在的结果用 would + 原形。 |
| 5 | If it rains tomorrow, we will stay at home.（if 子句用现在式代替将来式，不用 will） | if 子句永远不用 will。 |
| 6 | If I were rich, I would travel the world.（第二条件句 if 子句用过去式 were，不用 would） | if 子句不用 would，be 用 were。 |
| 7 | If she had known, she would have told me.（第三条件句主句要用 would have + 过去分词） | had known 之后主句要一致用 would have told。 |
| 8 | will miss | unless 等于 if not，子句用现在式，主句用 will。 |
| 9 | would have left | 倒装 Had I 等于 If I had，主句照用 would have + 过去分词。 |
