一、宾语从句的概念
宾语从句即句子作宾语,而不再是一个词或短语作宾语。 I like my teacher.(名词作宾语) I know him .(代词作宾语) I know Mr Li teaches English. (句子作宾语)
包含宾语Leabharlann Baidu句的句子结构: 主句+连接词(引导词)+宾语从句
e.g. 1. Ask him _w__h_e_th__er__(i_f_)_h_e_c_a_n__c_o_m_e. (他是否能来) 2. I don’t know _w_h_e_t_h_e_r_i_t_is__g_o_in_g__t_o_r_a_i_n_o_r_n__o.t (是否要下雨)
当句末为or not时,引导词只能用whether而不能用if.
3. The teacher told us (that) _t_h_e__e_a_rt_h__m_o_v_e_s__a_ro_u_n__d_t_h_e_s_u_n. (地球围着太阳转)
注意:当从句是客观真理的时候,无论主句什么时态,从 句一律用一般现在时

I didn’t know who he was. 这四个句子是由连接代词 who, 和连接 副词 where, why 引导的宾语从句。
在口语当中往往省略
e.g. 1. I hear (that) ___h_e_w__il_l_g_o__to__B_e_ij_i_n_g____. (他会去北京) 2. He said (that) __h_e_m__i_ss_e_d__u_s_v_e_r_y_m__u_c_h_. (他非常想念我们)
