表示主句动作发生的特定时间，既可指时间点，也可指时间段。从句的谓语动词可以是延续性动词，也可以是非延续性动词；从句的动作和主句的动作既可同时发生，也可以是先后发生。Itwassnowingwhenhearrivedatthestation.延续性动词和非延续性动词Grammarfocus如：work,study,drink,eat等。

延续性动词指动作可以延续一段时间，而不是瞬间结束。

非延续性动词指动作极为短暂，瞬间结束。

如：

start,begin,hit,jump,knock等。Grammarfocuswhen引导的时间状语从句(when后面的是从句）1.

Myfathercame,IwaswatchingTV.2.Whentherainstormcame,Marywasdoingherhomework.3.Ilostthewaywhentheskybecamedark.用when引导的时间状语从句时，主从句的时态要保持一致，如果主句时态是过去时，从句也必须用过去的某一种时态。如果主句时态是现在时，那么从句也应该是现在的某一种时态。从句过去时，主句过去进行时。GrammarfocusWhileLindawassleeping,Jennywashelpingmewithmyhomework.Mary’smothercamebackfromworkwhileshewassleeping.PeterlikesMathwhilehissisterlikesEnglish.

while引导的时间状语从句强调主句动作在从句动作进行的过程中发生，从句的谓语动词必须为延续性动词，常用进行时。while也可以用来表达“然而”。while引导的时间状语从句强调两个动作同时进行。主句过去时，从句过去进行时PresentationLookatthetableandwritesentenceswithbothwhileandwhen.JohnMarytakephotosbuyadrinkplaythepianoleavethehousecleanhisroomturnontheradioshoptakethecartothecarwashWhileJohnwastakingphotos,Maryboughtadrink.JohnwastakingphotoswhenMaryboughtadrink.4aPresentation1.WhileJohnwasplayingthepiano,Maryleftthehouse.
