need动词后面什么时候加to什么时候不加to?请举例说明。
1. 当人作为主语时，需要使用动词不定式，即在"need"后面加上"to"再加上动词原形。例如："The students need to study hard."（学生们需要努力学习。）2. 当提到的事物或抽象概念作为主语时，使用动名词形式，即在"need"后面直接跟动名词，不加"to"。例如："The library needs updating."（图书馆需要更新。）
3. 当谈论物体需要被动的动作时，使用不定式的被动形式，即在"need"后面加上"to"再加上"be"再加上动词过去分词。例如："The car needs to be repaired."（这辆车需要被修理。）
