语法专题复习--名词性从句

命题规律
纵观近五年的高考，对名词性从句的考 查主要集中在以下几点：
1.考查连接词的正确选用。这些易混的连接词主要 有：what/that/which; whether/if; what/whatever; who/whoever; where等 2.考查名词性从句的语序，名词性从句总是用陈述 语序。 3.考查it作形式主语和形式宾语的用法。
【学以致用】
• 1._I_t _is__p_o_s_s_ib_l_e_t_h_a_t_(很可能)she will come back tomorrow.
• 2._It_i_s_o_b__v_io_u_s__th_a_t___(很明显)this measure is effective. 3._I_t _is__re_p_o__rt_e_d_t_h_a_t___(据报道)20 people were killed in the accident.
that 只起连接作用，无意义，在从句中不充当任
何成分。
what 既起连接作用, 又在从句中作 主语, 宾语, 表
语。
