小結(jié)：while引導(dǎo)的時間狀語從句的謂語動詞必須是可延續(xù)的，而when引導(dǎo)的時間狀語從句的謂語動詞是可延續(xù)的，也可以是表短暫性動作的動詞。2).Whenyouhavefinishedyourwork,youmayhavearest.

小結(jié)：從句動作發(fā)生在主句動作之前時，只能用when引導(dǎo)這個從句，而不能用while。2.用while,when填空：①_____________Iwaswalkingdownthestreet,Inoticedapolicecarinfrontofthestore.②____________Johnarrived,Iwascookinglunch.③Iwaswandering（徘徊）throughthestreet_________Icaughtsightofatailor’sshop.When/WhileWhenwhen總結(jié)：相當(dāng)于andatthis/thattime。意思為“正在/剛要……這/那時（突然……）”3、When的特殊用法Wewerehavingaclasswhensomeonebrokein.(突然有人闖了進(jìn)來).Wewereabouttosetoffwhenitbegantorain.(這時開始下雨了)4).until/till(不用于句首)Hedidnotgotobeduntilhefinishedhiswork.（直到…才…）=Notuntilhefinishedhisworkdidhegotobed.
