语法全解：
when和while 都表示主从句的动作或状态同时发生，但二者意义不尽相同。
1. when引导的从句可表示时间点，也可表示时间段，从句的位于动词既可以是延续性动词，也可以是非延续性动词；while引导的从句通常表示时间段，从句中宜用延续性动词作谓语。 They arrived while we were watching TV.
2. 含有when引导的时间状语的主从复合句，如果主句用过去进行时，从句应该用一般过去式，表示一个动作正在进行的时候另一个动作发生，强调后一动作发生的突然性。 We were watching TV when suddenly the lights went off.
3. 当主从句的动作都是延续的或同时发生，主从句都用过去进行时的时候，从句多用while引导。 They were reading while we were writing .
4. 如果表示从句的动作在主句的动作“之前”或“之后”发生时，多用when，不用while。 此外，when还含有“at the moment “的意思，此时引导的句子不能放在句首，也不能用while来替换
主谓一致判断法
主谓一致是指在一个英语句子中，主语和谓语在人称和数上要保持一致，这种一致性体现在联系动词be和助动词do, have的人称和数上，以及实义动词的第三人称单数上
1. 不可数名词作主语时，谓语动词用单数形式
2. 动名词或动词不定式作主语时，谓语动词用单数形式
3. Either…or… : neither…nor…: not only…but also…: 连接两个名词或代词作主语时，谓语动词与邻近的名词或代词在人称和数上保持一致。
4. 在here : there 开头的倒装句中，谓语动词与后面的珠玉在数上保持一致。
