whenvswhile

这两个词都有“当…的时候”的意思。when既可指某一点时间,也可以指一段时间;while强调一段时间,所以从句的谓语动词常是延续性的。当when表示“在某一段时间里”的意思时,它可以代替while,但while不能代替when.e.g.WhenIcamehome,shewascookingdinner.当我到家时,她正在做饭。Whenyouhangwetclothesnearafire,youwillseesteamrisingfromthem.当你把湿衣服挂在火边时,你会看到水汽从衣服上升起。1.Matchthesentenceswiththepictures.1.____He’sscared.2.____It’sclimbingatree.3.____It’sjumpingdown.4.____She’sshouting.恐惧的攀登;爬跳跃呼喊;呼叫cdba2a.Listen.Checkthesixthingsyouhear.Action1.sawacat
