英语中，从句是一种非常重要的语法结构。从句可以用来描述时间、原因、条件、结果、目的等，用法非常灵活。
名词性从句
名词性从句可以在句子中充当主语、宾语、表语和同位语。例如：
- 主语从句：What he said surprised me. (他说的话让我惊讶了。)
- 宾语从句：I don't know where he is. (我不知道他在哪里。)
- 表语从句：The problem is that she is always late. (问题在于她总是迟到。)
- 同位语从句：His hope, that he would get the job, was shattered. (他的希望，即得到这份工作，破灭了。)
形容词性从句
形容词性从句用来描述名词或代词的特征或状态。形容词性从句通常由关系代词（who, whom, whose, which, that）引导。例如：
- The man who is standing there is my friend. (站在那里的那个人是我的朋友。)
- The book that I bought yesterday is very interesting. (我昨天买的这本书非常有趣。)
副词性从句
副词性从句可以用来描述时间、原因、条件、结果、目的等。副词性从句通常由连词（when, while, because, since, if, although, unless, so that）引导。例如：
- Time：I will call you when I arrive in New York. (我到达纽约后会给你打电话。)
- Reason：I didn't go to the party because I was sick. (我没去参加派对，因为我病了。)
- Condition：You can come to my house if you want to. (如果你愿意的话，可以来我家。)
- Result：She studied hard so that she could pass the exam. (她努力学习，以便通过考试。)
- Purpose：He took a taxi in order to catch the train. (他打车，为的是赶上火车。)
在使用从句时，需要注意句子的结构和语法。掌握好从句的用法，可以使我们的英语表达更加准确、流利。
