问题描述：
当他做完作业时,他的妈妈将正在厨房做晚饭的英文怎么说?
答
●When he finishes his homework, his mother will be cooking dinner in the kitchen.=● His mother will be cooking dinner in the kitchen when he finishes his homework . 说明：从主要子句中的（will be cooking）可得知师太是未来式,本来副词句子中应该是（will finish）,但因连接词语是when,所以要用现在式（finishes）来代替未来.
主要句子→进行式,动作持续进行.副词句子→简单式,动作瞬间发生.
★when + S + V ,S + be V + Ving .
★S + be V+ Ving + when + S + V .
