【宾语从句练习题】在英语语法中，宾语从句是一个非常重要的知识点，它不仅在阅读理解中频繁出现，也是写作和口语表达中的常见结构。掌握好宾语从句的用法，能够帮助我们更准确地表达自己的想法，并提高语言的流畅性与准确性。
那么，什么是宾语从句呢？简单来说，宾语从句就是在一个主句中充当宾语的句子。它通常由连接词（如that、whether、if、what、when、where、why、how等）引导，放在动词或介词之后。例如：
- I think that he is right.
- She asked if I could come.
- They don’t know where she went.
在这些句子中，“that he is right”、“if I could come”和“where she went”都是宾语从句，分别作动词“think”、“asked”和“know”的宾语。
