总结部分：
1. 当remain作不及物动词时，含义为①停留，留在（某地），搭配结构为“remain+介词+地点名词”，对应例句“Only a few students remained in the classroom after class.”；
2. 当remain作系动词时，可接形容词，含义为②保持（某种状态），搭配结构为“remain+形容词”，对应例句“He remained calm even in danger.”；也可接分词（v.-ing, v.-ed），词性为③系动词，含义为“保持(某种状态)”，搭配结构为“remain+分词”，对应例句“They remained standing for the whole meeting.”。

1. (1)“待在教室”对应remain作不及物动词的用法，结合语境“After school ended”可知用一般过去时，故填remained in the classroom；
2. (2)“一直坐在”对应remain+现在分词的用法，用一般过去时，故填remained sitting；
3. (3)“保持沉默”对应remain+形容词的用法，用一般过去时，故填remained silent。
