及物动词都可接宾语从句吗
有网友在本站“答疑中心”问：是不是所有的及物动词都可接宾语从句。现简单答复如下：
可以这样认为，所有及物动词都可接宾语从句。
对于 hear, say, tell, think, believe, suppose等动词后接that引导的宾语从句，这是大家都很熟悉的用法。如：
I was very sad to hear that your mother had died. 听说你母亲去世，我很难过。
They say that hardship is good for the soul. 他们说艰难困苦对心灵有益。
You could tell that they were itching to leave. 你能看出来，他们渴望离开。
I think that we should stick around until we get an answer. 我认为我们应该留下来直到我们得到一个回答。
Doctors believe that smoking is harmful to your health. 医生们认为抽烟会危害健康。
但是，eat, drink, buy, sell 这样的动词也可以接宾语从句吗？它们好像通常是接名词或代词作宾语啊！
没错，eat, drink, buy, sell, make 这样的动词通常是接名词或代词作宾语，但它们也可以接宾语从句，如what, whatever 引导的宾语从句。如：
She can eat whatever she likes and she never gets fat. 她可以想吃什么就吃什么，而且从不发胖。
We’ve got to be practical and buy what we can afford. 我们得讲求实际，只买我们买得起的东西。
He tried to make what he was saying sound less definite. 他试图让自己所说的话听起来不那么肯定。
可见，原则上说，凡是能名词或代词作宾语的及物动词，均可以接 what, whatever等引导的宾语从句，因为这类从句相当于“名词或代词+which / that引导的定语从句”，换句话说，这类从句其实本质上与名词或代词是一样的。
