少兒英語(yǔ)學(xué)習:現在完成時(shí)與過(guò)去完成時(shí)的用法區別，少兒英語(yǔ)學(xué)習 今天小編帶大家來(lái)看一下少兒英語(yǔ)第18課的“每課一句”希望對大家有所幫助。
　　 一、課文原文
　　Lesson 18 He often does this!
　　After I had had lunch at a village pub, I looked for my bag. I had left it on a chair beside the door and now it wasn't there! As I was looking for it, the landlord came in. 'Did you have a good meal?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The landlord smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said. 'My dog had taken it into the garden. He often does this.'

　　二、每課一句My dog had taken it into the garden.
　　這句話(huà)有的人會(huì )問(wèn)，為什么不用現在完成時(shí)？即：
　　My dog has taken it into the garden.
　　如果用的是現在完成時(shí)，這句話(huà)的意思是：
　　我的狗已經(jīng)把你的包叼到花園里去了。這就說(shuō)明，店主說(shuō)這句話(huà)的時(shí)候，作者的包還在花園里。但是，其實(shí)這個(gè)時(shí)候店主已經(jīng)把作者的包拿回來(lái)了。店主用過(guò)去完成時(shí)來(lái)表達，就表達出了上面的含義，即：店主把包拿回來(lái)（過(guò)去的動(dòng)作）之前，他的狗把包叼到花園里了（過(guò)去的過(guò)去）。
　　三、更多拓展As I was looking for it, the landlord came in.
　　句中的as的用法與while差不多，其引導的從句一般要用進(jìn)行時(shí)，其主句動(dòng)作如果是持續動(dòng)詞，一般也要用進(jìn)行時(shí)。
　　本句話(huà)中的come in沒(méi)有用進(jìn)行時(shí)，是因為come in是瞬間動(dòng)作。
