由特殊疑问词引导的宾语从句
当宾语从句是特殊疑问句时，疑问词就是连词，这时疑问词不可省略，而且宾语从句要用陈述语序。
连接代词：wh，whm，whse，which，what 
连接副词：where，hw，why，when
结构 : 1. 主语 + 谓语 + wh- + 从句 2. 主语 + 谓语 + wh- + 谓语 + ...
连接代词 VS 连接副词
Culd yu tell me wh  knws the answer ?They dn't knw what is in their bags .

Let’s learn.
Tm says his sister always wears black pants. his sister wre black pants last year.his sister _________ black pants next year.
时态要：前后呼应 a. 主句是一般现在时，从句根据实际情况选用不同的时态；( 主现从任 ） b. 主句是一般过去时，从句要用相应的过去时态。( 主过从必过 ） c.若从句表示自然规律,客观事实,科学事实真理或名言警句等时，无 论主句用任何时态，从句仍用_一般现在时。 ( 真理永一现）
1. —Miss Sng, I haven't decided ________. —I really hpe yu will visit it. It's a gd chance t learn abut the histry f ur city.A. hw will I g t Suqian Museum B. hw I will g t Suqian MuseumC. whether will I g t Suqian Museum D. whether I will g t Suqian Museum2. — Culd yu tell me ________? — He likes the Science Museum best.

3. - Mum, culd yu tell me we need t visit my grandparents every week? -They will be happy t see us. A. what B. why C. where D. hw4. -That sunds interesting! May I ask t see the changes? - Well, it depends. Sme peple take a while, and sme thers take frever.A. hw much will it cst B. hw lng will it takeC. hw much it will cst D. hw lng it will take
当主句的谓语是think, believe, guess, suppse等表示“认为、相信、猜想、期望”等意思的动词时：主句的主语是第一人称, 时态为一般现在时时, 从句的否定一般要转移到主句上。I think teenagers shuld be allwed t chse their wn clthes.（改为否定句）→I dn't think teenagers shuld be allwed t chse their wn clthes.我认为青少年不应该被允许选择自己的衣服。
宾语从句与复合不定式短语的互换
1. 若主句的主语与从句的主语一致，则由疑问词引导的宾语从句可以变成“疑问词+动词不定式”这一结构。 I dn't knw hw I shuld d it next.= I dn't knw hw t d it next.

• 宾语从句须注意，几点事项应牢记。• 一是关键引导词，不同句子词相异。• 陈述句子用that；一般疑问是否(if / whether)替；• 特殊问句更好办，引导还用疑问词。• 二是时态常变化，主句不同从句异；• 主句若为现在时，从句时态应看意；• 三是语序要记清，从句永保陈述序。
