宾语从句（引导词that, if, whether) 人教版九年级上册 Unit 3 Smart Learning 第一部分 核心语法精讲与练习 一、宾语从句（that / whether / if） 1. 概念对比 连接词 核心含义 用法说明 教材例句 that 引导陈述句作宾语从句，无实际意义，可省略 常用于 believe, think, know, find, suggest 等动词后 I believe (that) reading is important for learning. whether / if 引导一般疑问句作宾语从句，意为"是否" 常用于 wonder, want to know, ask 等动词后 I wonder if / whether you could help me. 易错提醒 ① 宾语从句必须用陈述语序（主语在前，谓语在后）。 ② whether 可与 or not 连用，介词后只用 whether。 ③ 主句为过去时，从句时态通常要作相应变化。 2. 判断小技巧 • 从句是陈述事实/观点，用 that（可省略）。 • 从句带有"是否"的疑问含义，用 whether / if。 • 句末有 or not，或放在介词后时，优先用 whether。 语法练习 A —— that / whether / if 填空 用 that, whether 或 if 填空。 1.

He needed to pass a qualification exam in a subject he had never studied before. He only had 48 hours. Instead of giving up, he decided to use AI as a learning partner. But he didn't ask the AI for direct answers. Instead, he uploaded textbooks and research papers, then kept asking deep questions. "Why does this theory work?" "How is it different from other ideas?" He wrote down the AI's answers and compared them with his own thinking. "The key is active learning," he said later. "AI can give you information quickly, but you have to question it, organize it, and reflect on it yourself." After 48 hours of hard work, he passed the exam. His story teaches us that technology is just a tool. The real power comes from the learner's own curiosity and critical thinking. As one expert said, "It is not just about what AI can teach you, but how you use it to think." 1. How much time did the student have to prepare for the exam? A. 24 hours. B. 48 hours. C. One week. D. One month. 2. What did the student NOT do while using AI? A. Upload textbooks. B. Ask deep questions. C. Get direct answers. D. Compare information. 3. What does the student think is the key to learning with AI? A. Getting information quickly. B. Active learning and critical thinking. C. Using expensive tools. D. Studying all the time. 4. What can we learn from the story? A. AI can replace human teachers completely. B. Students should never use AI. C. The learner's own thinking is the real power. D. Exams are not important. 5. What is the best title for the passage? A. AI Replaces Teachers B. A 48-Hour Learning Miracle C. The Future of Schools D.

I believe that anyone can become better if they keep trying and never give up. Last month, I tried a new way to learn English grammar. I used an AI app, but I didn't ask it for answers directly. Instead, I kept asking it deep questions like "Why do we use this tense?" I found that this method helped me understand the rules better. My teacher suggested that I should keep doing this because it trains my thinking. At first, I wondered if AI could really help me improve. Now I know that the real power comes from my own thinking, not just from the tool. I also understand that making mistakes is not bad because it shows me how to improve. I believe that active learning is the best way to success. 1 学科网（北京）股份有限公司 $
