whenvswhile

這兩個詞都有“當…的時候”的意思。when既可指某一點時間,也可以指一段時間;while強調(diào)一段時間,所以從句的謂語動詞常是延續(xù)性的。當when表示“在某一段時間里”的意思時,它可以代替while,但while不能代替when.e.g.WhenIcamehome,shewascookingdinner.當我到家時,她正在做飯。Whenyouhangwetclothesnearafire,youwillseesteamrisingfromthem.當你把濕衣服掛在火邊時,你會看到水汽從衣服上升起。1.Matchthesentenceswiththepictures.1.____He’sscared.2.____It’sclimbingatree.3.____It’sjumpingdown.4.____She’sshouting.恐懼的攀登;爬跳躍呼喊;呼叫cdba2a.Listen.Checkthesixthingsyouhear.Action1.sawacat
