名词性从句之宾语从句和表语从句精品PPT课件

3. 当宾语从句是特殊疑问句时，由疑问词 （what, who, whom, which；whose； when, where, how, why等）引导，因为疑问词在 从句中担任一定的句子成分，具有一定的 意义，所以不可以省略
Do you know what he said just now ? I don’t remember when/where we arrived . I asked him where/how/why I could get so much money . Please tell me who \whom\what we have to see .
Everyone knew what happened and that she was worried.

特殊疑问词
特殊疑问句
一、连接词（引导词） 1. 当宾语从句是陈述句时（包括肯定句和
否定句），连词由that引导，因为that在从 句中不作任何成分，也没有任何具体意思， 因此在口语或非正式文体中常省略
Lin Tao feels (that) his own team is even better.
2.如果主句是过去的时态，那么从句的时 态一定要用相对应的过去的某种时态 （包括一般过去时，过去进行时，过去 将来时， 过去完成时）
I knew who lived here. (live) I saw she was talking with her mother. (talk with) He was wondering whether his father would come back tomorrow. (come back) He said that he had seen it . (see)
二、时态
1. 如果主句是现在的时态 ，从句的时态可根 据实际情况而定，（包括一般现在时，一般过 去时，一般将来时，现在完成时等）
I know he lives here . ( live ) I know he lived here ten years ago . (live) I have heard that he will come tomorrow . (come)
1. Mike insisted that we __(_s_h_o_u_ld_)__n_o_t _b_e___
(be)late for school. 2. The doctor ordered

she
_(s_h_o__u_ld_)_s_t_a_y__
