23、第一类：that，没有意义，仅起连接作用；连接的从句为陈述语气；在宾从和表从中可以省略，在主语从句中不能省略。第二类：if/whether，有“是否”的意思；连接的从句为一般疑问语气；在宾从中有只用 whether 不用 if 的 5 种情况，在主从中 if 不能位于句首，在表从中不用 if,只有 as if.(保险起见，所有名词性从句中首选 whether)。第三类：连接代词，what, which, who , whom, whose, whatever, whoever, whomever, whichever 等,他们在从句要充当成份，作主语,宾语（除 whoes） 。作定语（what, which, whose, whatever, whichever）。第四类：连接副词，when, where, why, how, however, whenever, wherever等，在从句中作状语，也就是说，从句中缺少时间，地点，原因，方式等语意的时候要用他们。（若从句中主谓或主谓宾齐全就要根据句意相应的用他们）同学们，通过对名词性从句的进一步学习，你是否有新的收获呢？5若有任何建议都可以提出来的哟，你也可以留便条在讲桌上的。希望童鞋们天天进步，学习开心。
