2、点荟萃 名词性从句一直备受高考命题者的关注，近几年来的高考题主要考查在具体语境中连接词的选择，尤其是连接词what和that的辨析，以及whether 与if表示“是否”时的区别。因此，正确区分名词性从句的类型，根据在从句中的作用和所表达的意义，确定恰当的连接词是一轮复习的重点。此外，名词性从句和定语从句的辨析，也是高考考查的重点。2021/8/11 星期三3一、认识各种名词性从句 名词性从句相当于名词，可分别作句子的主语、表语、宾语和同位语。因此，名词性从句具体分为主语从句、表语从句、宾语从句和同位语从句。名词性从句中的连接词有连词that/whether/if，连接代词what/who(m
