Unit3 课时4 SestionA Grammar Focus 课件 2026-2027学年人教版英语九年级上册

该初中英语课件聚焦that、if/whether引导的宾语从句，系统讲解引导词、语序、时态三要素。课堂导入通过视频《I believe I can fly》创设情境，从简单句与复合句对比切入，以例句分析和语法成分标注为支架，帮助学生衔接已知与未知知识。 其亮点在于以“理解-应用-迁移”为主线，通过填空、语篇补全（如4b选择引导词）提升语言能力，结合华罗庚学习经历的语篇（4d）引导学生迁移知识表达观点，培养思维品质。小结用框架归纳三要素，学生能从语境应用到自主表达，教师可借助分层活动提高教学效率。

She will come back in two weeks I hear . 我听说她两周后会回来。 3. He works very hard. Do you know ? 你知道他学习很努力吗? she can swim he works very hard that she will come back in two weeks that that Grammar 当主句的主语为第一人称(I、we),且谓语动词是think, guess, believe等时,如果宾语从句要表达否定含义,通常要遵循“否定前移”原则,即只否定主句,不否定从句。 I don’t think this novel is boring. 我认为这部小说不枯燥乏味。 whether/if引导的宾语从句 whether与if通常可以互换,且常跟在ask、know、 find out、wonder、decide、see、doubt、unsure、 uncertain等之后引导宾语从句,引出两个或以上的可 能性之一; whether/if在从句中也不充当任何成分(翻译成“是否”),只起连接作用.

I want to know. whether/ if he has had supper whether/ if you are a student whether/ if he likes milk whether/ if they watched TV if they will come tomorrow Grammar 引导词用法小结: • 当主句后面跟一个陈述句时,通常用 连接(可以省略)。 • 当主句后面跟一个一般疑问句时,通常用 或 连接,意思是“是否”。后直接接“ ”、“ ”“ ”时,只能用 。 当宾语从句是特殊疑问意义时,用 特殊疑问词引导,不省略。 Do you know “ what did he say ?” Do you know what he said ? Can you tell me “ when will he arrive ?” Can you tell me when he will arrive ? Do you know “ where does he live ?” Do you know where he lives ? 三、由特殊疑问词引导的宾语从句 Grammar 1 . Why is the train late ?
