难度较大语法专项训练：完成时态

初三语法专项训练：现在完成时用法小结现在完成时的构成：助动词have（has）+过去分词，1．表示过去发生或完成的某一动作对现在造成的影响或结果。例如：Ihavejustcleanedmyclothes.我刚洗过衣服。（“洗衣服”是发生在过去的动作，对现在造成的结果是“衣服干净了”）现在完成时常用的时间状语有：already（”已经”用于肯定句的中间和末尾处）never(“从不”用于中间处)ever（”曾经”用于疑问句和肯定句的中间处）just (“刚刚”用于中间处)yet (“已经”用于疑问句的末尾处/“还”用于否定句的末尾处)或不加任何的时间状语，但不能和表示过去的时间状语连用.现在完成时与一般过去时的用法比较现在完成时表示过去的动作一直延续到现在甚至会继续下去或表示过去的动作对现在造成的影响；一般过去时表示动作发生的时间在过去。试比较：Theplanehasarrived.飞机已经来了。（说明现在的情况：飞机在这儿）Theplanearrivedaquarterago.飞机是一刻中以前来的。（强调动作发生的时间在过去）Ihavetaughthereforfifteenyears.我在这儿已经教了十五年。（表示十五年前的动作一直延续到现在，还可能会继续。）Itaughthereforayear.我过去在这儿教过一年。（表示“我“现在已经不在这儿任教了）练习：I．翻译下列句子：你曾经吃过鱼和薯条吗？我刚刚丢了我的化学书。我以前从来没去过那个农场。他已经吃过午饭了。你已经看过这部电影了吗？我哥哥还没回来。我上星期看过这部电影。在1992年他住在这里。II．用过去时或现在完成时填空：1.“_________you__________(have)lunch?”“Yes.”“When________you__________(have)it?”“I____________(have)itat12:00.”2.“_________you__________(write)alettertoyourauntyet?”“Yes,I___________.I________________(write)onelastweek.”3.“_________he___________(finish)hishomework?”“Notyet.”4.“_________theyever__________(be)abroad?”“Yes,justonce.”5.Yourfather_________just___________(finish)hiswork.6.Yourfather_________(finish)hisworkjustnow.7.LasttermI__________(learn)manyEnglishwords.8.They____________(notread)theinterestingbooksyet.9.He_____________never____________(go)tothesciencemuseum.10.____________youever____________(drink)coke?11.“____________you_____________(buy)adictionary?““Yes,I__________.”“Where__________you_____________(buy)it?”“I___________(buy)itinabookstore.”“When___________you_____________(buy)it?”“Yesterday.”Since和for的用法表示过去已经开始持续到现在的动作或状态常用的时间状语有：for,since,howlong,sofar,thesedays等。Since+过去点的时间，for+一段时间（数词+量词），此划线部分用howlong提问。一、since短语或从句表示过去的动作延续至今，since之后的时间为一点。如：Mr.Smithhasworkedheresince1984.1984年以来，史密斯先生一直在这工作。He’slearnedabout5,000Englishwordssincehewenttocollege.他上大学以来大约学了五千个英语单词。二、for短语表示动作延续多长时间，for的宾语为时间段。如：Wehaveknowneachotherfortwentyyears.我们认识有二十年了。Ihaven’tseenherforalongtime.我好久没有见到她了。练习：用since和for填空1)______twoyears
