7、語從句中。例： She was playing games when her father went tocook this time yesterday. His father came back when Jagger was drivingthe car. Olivia was looking at me while we were taking a photo. 1）主句動作先于從句動作， 主句：過去進(jìn)行時(shí)； 從句：一般過去時(shí)。2） 從句動作先于主句動作， 主句：一般過去時(shí)； 從句：過去進(jìn)行時(shí)。3）主從句動作無先后關(guān)系， 同時(shí)使用過去進(jìn)行時(shí)，從句一般由while引導(dǎo)。 四、習(xí)題演練1.
