关于宾语从句作介词的宾语，现详细解析如下：
一、介词可后接宾语
介词后面的内容就是宾语，如：
The movie is about a dog and a cat.
这部电影是有关一条狗和一只猫的。
（介词about关于的内容是a dog and a cat，所以a dog and a cat是about的宾语）
二、介词后接宾语从句
介词后面的内容若是句子，那么该句就是宾语从句，如：
She is angry at what you did.
她对你所做的事感到生气。
(介词at后接宾语从句 what you did)
三、大部分介词不接that或if引导的从句，可接由其他引导词引导的从句
He is only interested in who has won the election.
他只对谁赢了选举感兴趣。
It depends on whether you can handle the problem.
这取决于你是否能处理这问题。
She has a different opinion over how the machine works.
她在这机器是如何运作的问题上有不同的意见。
四、except/but等个别介词可接that引导的从句
He remembers everything except that he has a wife.
他什么都记得，但不记得他有个老婆。
She said nothing except that she was all right.
她什么也没说，只说她挺好。
She knew nothing but that you were upset.
她什么都不知道，只知道你心情不好。
I saw nothing except that she walked as if she were carrying something.
我什么都没看见，只看见她走路时好像拿着东西一样。
