WhenWhile

when:时间点，时间段。

动作可以先后发生，也可以同时发生

when＋从句（动作可以短暂性，也可延续性动词）while：只指时间段。

强调主句动作在从句动作发生的过程中，也可以是主从句动作同时发生。

while＋从句（延续性动词）

短暂性词时，用过去时，延续性词时，用过去进行时When主句（延续性词－进）when＋从句（短暂性词－过去时）

when（延续性词－进），主句（短暂性词－过去时）＝主句（短暂性词－过）when（延续性词－过去进行）While

While＋从句（延续性词－进），主句（短暂性词－过）＝主句（短暂性词－过）While＋从句（延续性词－进）

While＋从句（延续性词－进），主句（延续性词－进）

所以，主从句同时进行时，一般用“while”找出“延续性词”“短暂性词”1.Whenwe____________(have)dinner,myuncle______(arrive).2.Mymother______________(wash)thedisheswhenI_____(get)homeyesterday.3.I____________(eat)dinnerwhentheearthquake____________(happen).4.I___________(walk)inthestreetwhensomeone___________(call)me.5.

Whenhe_____________（shop)inthesupermarket,he_______(meet)oneofhisfriends.
