What are the differences? （2）在含有宾语从句的复合句中，宾语从句要用陈述语序。因此当特殊疑问句作宾语从句时，一定要注意语序。 “Where did he go last month?” She asked. = She asked where he went last month. 当疑问代词what/who在特殊疑问句中作主语时，该特殊疑问句本身即是陈述语序，所以转变成宾语从句后无需再调整语序。 “What’s wrong with the TV?” Tom asks. = Tom asks what’s wrong with the TV. 语序的变化 宾语从句可转化成“疑问词+动词不定式”结构 （3）宾语从句可转化成“疑问词+动词不定式”结构。 在含有疑问词引导的宾语从句的主从复合句中，如果从句的主语与主句的主语或宾语一致，则宾语从句可以转化为“疑问词 + 动词不定式”结构。 I want to know how I get there. → I want to know how to get there. 含有宾语从句的复合句与简单句的转换 (1)若主句的主语和从句的主语一致，可以将疑问词引导的宾语从句转化为“疑问词＋动词不定式”结构。 I don’t know what I should do next. = what to do (2)若主句的谓语动词是hope, agree, wish等，且主句的主语和从句的主语一致时，可以将that引导的宾语从句转化为动词不定式结构。 She hopes that she can get good grades. = to get (3)若主句的谓语动词是see, hear, watch, notice等时，其后由that引导的宾语从句可以转化为“宾语+宾语补足语(动词原形/动词-ing形式)”。 I heard that two girls were singing in the next room. = two girls singing 探究二：疑问词+不定式 宾语从句与动词不定式转化 I don’t know what I should do next. =I don’t know what ____ ____ next. 2.I wonder when we shall leave for Nanjing. =I wonder ______ ______ _____ for Nanjing. 3.

Pardon me, do you know...... 3. Could you tell me...... Speak more sentences politely. 如何改为宾语从句  What is she doing? Can you tell me?  Where does she live? Do you know? Can you tell me what she is doing? Do you know where she lives? 规律总结 1.含有宾语从句的句子结构： “主句+引导词+宾语从句” 2.特殊疑问句的引导词不变，就是特殊疑问词。 一般疑问句用if/whether 连接。 3. 引导词后面的句子由一般疑问句语序变为陈述语序。 （be动词和情态动词开头的特殊疑问保留； 助动词开头的特殊疑问去掉） 4.改写后句子，标点符号随主句。 把下列的句子改为宾语从句 1.“Who is he?” Do you know? 2. “Can you finish it by yourself?” he asks.
