能带宾语从句的形容词常见有：sure,glad,sorry,certain,worried,awareetc.,eg.We all agree with him on,what he said,.,I havent found my book yet;in fact,I am not sure,where I could have done with it.,I am aware,that you have been exceptionally kind to me.,4、同位语词news(idea,fact,hope,promise etc)+,同位语从句,eg.We heard the news,that our team had won.,The fact,that he hadnt said anything,surprised everybody.,I have no idea,when she will be back.,5.先行词（名词或代词）+,限定性定语从句,或先行词（名词或代词），+,非限定性定语从句,eg.Gone are the days,when Shanghai was a paradise for imperialist adventures.,Is this the restaurant,in which you work?,My elder sister,who is twenty,is now studying in the university.,6.主句+,状语从句,或,状语从句,，+主句注意逗号,eg.Speak to him slowly,so that he may understand you better.,No matter how difficult the work may be,we must surely complete it.,以上是从五个基本简单句型出发，根据各种从句的特点，通过列式显示各从句在主句中的位置关系。
