宾语从句2

2.如果主句是一般过去时，则宾语从句 常用表示过去的任意时态。例如：
1).He said that he was a cleaner .
2).I knew she had cleaned the house already .
3.如果宾语从句表达的是客观事实、真 理、自然现象、名言、谚语等时，主句 即使使用了过去时，宾语从句仍然用一 般现在时。 例如：
7.I think you _a_r_e_t_a_lk_i_n_g_ about the relay race now. (talk)
8.I didn’t know whom the letters ___w_e_r_e___ from. (be)
9.The radio says it __W_i_ll__b__e_ cloudy tomorrow. (be)
• 7. I’m not really sure_A__. • A. whether the plane will
be late • B. will the plane be late.

要点三：宾语从句的时态 （有三条规则）
1.如果主句是祈使句或是一般现在时或 一般将来时态，宾语从句可根据句意 选择任何一种时态。例如：
army. 我对他是否参军了很感兴趣。
3）当宾语从句移到句首表示强调时。例如： Whether this is true or not, I’m not sure.
这是否真实，我不敢肯定。
4)连词处于动词不定式前，用whether而不用if。 例如：
We decided whether to walk there.
在中考试题中，对宾语从句的考查主要 体现在三个方面：连词、语序和时态。近年 来对状语从句和宾语从句的混合考查更加频 繁，要注意综合分析。下面还有五道模拟中 考题，大家做做看。
1.I want to know if they__B__ the spring sports meeting next month. If they
2.当宾语从句是由一般疑问句变化而来时，用连 词if或whether引导，意思为“是否”，表示选择。 例如：
Could you tell us ? Will he really come here ? （合并句子）
Could you tell us if / whether he will really come here ?
1).Do you know who he was talking with at eight last night?
2). Please tell me how many pictures they have drawn .
3).Mary says she will come back soon .

3.当宾语从句由特殊疑问句变化而来时，则用该 特殊疑问词来引导宾语从句。例如：
A.if;whether B. whether;if C. whether;whether D. if;if

宾语从句三要点
一、宾语从句的概念
宾语从句：在复合句中充当宾语的从句叫宾语从 句，在句中作动词、介词的宾语。 eg. We know Mr Green teaches English.
Create an interest in what you lerrn. •宾语从句是初中英语教材中重点语法之一，也是 •中考一个考查热点。
I don’t know how many people there are in the room.
要点二：宾语从句的语序
宾语从句一律用陈述句语序。从句的 结构均为“引导词+主语+谓语+其他成 分”。
例如：1.We don’t know when they will arrive.
2.Could you tell me which way we must take to get to the museum?
例2.I don’t know __D_ he will come
tomorrw. ___ he comes, I’ll tell you.
(2005江苏)
A.if; Whether B.whether; Whether
C.if; That
D.if; If
解析：例２中，前一句是宾语从句，用if和 whether均可，但后一句为条件状语从句， 只能用if，故答案为D。
Could you tell me ? Where is the nearest post office ? （合并句子）
Could you tell me where the nearest post office is ?
注意：连接词作定语时，和它所修饰的词是不可 以分开的。例如：What time , which room , how many people等。例如：
2.Tom says that they _w__e_re__p_la_y_i_n_g_ (play) basketball at six o’clock yesterday evening.
3.I hear they _h_a_v_e_r_e_t_u_rn_e_d_ (return) it already.
4.He asked what they _w_e_r_e__d_o_in_g_ at eight last night. (do)
5.He said that they _h_a_d__b_e_e_n_ members of the Party since 1948. (be)
6. The teacher told his class that light _t_ra_v_e_l_s_ faster than sound. (travel)
