• 名词性从句包括主语从句，宾语从句，表语从句，同位语从句四种。• 判断名词性从句两步分析法；• 1 确定从句• 2 看从句在句中充当什么成分就叫什么从句• What he said is right . （主语从句）• I don’t understand what he said . （宾语从句）• This is what he said . （表语从句）• I have no idea that she quit her present job .（同位语从句） 名词性从句的连接词有 连接词；that whether（动宾从句可以用if） 连接代词；who whom whose which what 连接副词；when where how why 以及由连接代词和连接副词后面加上ever 【定义】一个句子在另一个句子中充当主语、宾语、表语、同位语，相当于名词，故称为名词性从句。【四大从句】名词性从句分为主语从句、宾语从句、表语从句和同位语从句。一、主语从句一个句子在另一个句子中充当主语，即句子充当主语，该句子称为主语从句。【完成例句】根据句意选词填空(that, if, whether, why, when, what)(1) That he will succeed is certain.
