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)
包含宾语从句的句子结构: 主句+连接词(引导词)+宾语从句

1. I hear (that) _______________________. (一小时后他 会回来) he will be back in an hour
2. He said (that)h_e_m__is_se_d__us__ve_r_y_m__u_ch______. (他非常想念 我们)
