引導词what是名词性从句学习的重点，正确使用what成为学习这类从句的一大难点。近年来高考多次对what在名词性从句中的用法进行考查，下面对what的一些用法作一简析。
一、What引导的名词性从句
1.What is most important in life isn’t money. （What 引导主语从句，在从句中作主语）
2.Will you show me what you bought？（What 引导宾语从句，在从句中作宾语）
3.She is no longer what she was five years ago. （What 引导表语从句，在从句中作表语）
4.I don’t know what machines they are making. （What 引导宾语从句，在从句中作定语）
What引导的名词性从句时，what用作连接代词，可引导主语从句、表语从句、宾语从句，且在上述从句中充当主语或表语或定语或宾语，含义为“什么；……的（人、事、物）”。
二、What与that引导名词性从句的区分
分析下列从句中的what与 that：
1.What on earth she is is still a mystery.
2.That you are coming to London is the best news.
3.He could understand what I said.
4.I heard that he had joined the army.
5.Our plan is that we will go there once a week.
6.Can you show me what books you like？
▲小结：that 连接词，在从句中仅其连接作用，不做任何成分，无词义。
what 连接代词，在从句中不仅起连接作用，且在从句中充当主语、表语、定语或宾语，有词义。
