He said (that) he felt sick. ◆ ② 一般疑问句充当宾语 → 用 if 或 whether 引导（不可省略） She asked me if/whether I could help her.（她问我是否能帮她） I wonder if/whether it will rain tomorrow.（我想知道明天是否下雨） ⚠️ 与or not连用或放在介词后时，必须用whether I don't know whether he will come or not.（不能说if...or not） ◆ ③ 特殊疑问句充当宾语 → 用原来的疑问词(what/who/when/where/how/why) Do you know where he lives?（你知道他住在哪里吗？） Can you tell me how I can get there?（你能告诉我怎么到那里吗？） 要素二：语序（必考！） ◆ 宾语从句必须用陈述语序（主语在前，谓语在后） ✅ I don't know what he wants.（陈述语序：what + 主语 + 谓语） ❌ I don't know what does he want.（错误！疑问语序） ✅ Could you tell me where the meeting is? ❌ Could you tell me where is the meeting? 要素三：时态呼应 ◆ 主句为现在时 → 从句可用任何时态（根据实际需要） I think he is right.（现在）I think he was right.（过去）I think he will be right.（将来） ◆ 主句为过去时 → 从句须用过去的某种时态（时态后退） He said he was busy.（现在→过去）He said he had finished.（过去完成） ⚠️ 客观真理不受主句时态影响：He said the earth moves around the sun. 【三、if 双重身份辨析（必考！）】 ◆ if 引导宾语从句 = 是否（是否做某事） I wonder if it will rain tomorrow.（我想知道明天是否下雨——宾语从句） ◆ if 引导条件状语从句 = 如果（主将从现） If it rains, I will stay at home.（如果下雨我就待在家——条件状语从句） 区别方法：if 表示"是否"→宾语从句；if 表示"如果"→条件状语从句 【四、连接词辨析总结】 ◆ 转折对比：but（但是）, however（然而）, while（而）, on the other hand（另一方面） I like texting, but I prefer face-to-face talk. ◆ 原因结果：because/since/as（因为）, so/therefore（所以） Since we misunderstood each other, we need to talk again. ◆ 时间顺序：when/while/after/before/as soon as After you finish reading, we can discuss it. 【五、直接引语与间接引语（了解）】 ◆ 直接引语变间接引语时，人称、时态、指示代词、时间状语需相应变化 直接：Tom said, "I am busy now." 间接：Tom said that he was busy then. 六、巩固练习 一、单词/短语填空 1.
