2、 common/unusual/interesting hobby? 语法现在完成进行时二.【重难点分析】1. 现在完成进行时构成：肯定句：主语+ have / has been + doing 否定句：主语+have/has+not+been+doing 一般疑问句：Have/Has+主语 +been+doing? 现在完成进行时表达“ 某一动作从过去开始一直持续到现在，有可能还要持续下去” ，现在完成进行时的句子中多用延续性动词，如：live ，learn，study，work 等。(1) I have been collecting stamps since I was ten year
3、s old. 我从十岁起就一直在集邮。(3)我学英语已经十年了。_ 在这几个句子中， have 和 has是助动词， 疑问形式需把助动词提前，否定形式在have或 has后面加 not， have not和 has not可以分别缩写成havent和 hasnt，如：(1)Has he been writing the letters to his friend? 他是一直在给他的朋友写信吗？(2)我有很长时间没有看电影了。_ （表明没有看电影这个动作从过去一直持续到现在，还要继续持续下去。）2.现在完成进行时与现在完成时的区别：(1)现在完成时强调动作的完成，而现在完成进行时侧重的是动作的持
4、续进行。如：I have read a book about birds. （已经读完）I have been reading a book about birds.（一直都在读，现在还在读，有可能会继续读下去）(2)两种时态都有延续性，但现在完成时往往只说明一个事实，一种影响或结果，无感情色彩；现在完成进行时表示一个动作的延续、重复，有时有一定的感情色彩。如：She has been singing all the day. 她都唱了一整天了。（抱怨、厌烦）三.【重点词汇】1. since的用法：(1)conj (引导时间状语从句，从句中常用过去时，主句用一般时态或完成时)自从 以来； 以后
5、egIt was years since l had seen her自从我见到她(到那时 )又过去好几年了。我们到这儿刚好有一周了。_ (引起原因状语从句，通常置于句首)既然；因为eg既然他这么说，那一定是真的。_ (2)prep自 以来egI have lived here since childhood 自小我就住在这儿。1993 年以来他还没有回过家。_ (3)adv精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - - - - -第 1 页，共 6 页 - - - - - - - - - - (与完成时态连用)从那以
6、后；后来egHe left the city in 1985 and has returned only once since 他 1985 年离开这座城市，自那以后只回来过一次。以前(4)构成短语： ever since从那以后 (一直 ) long since很久以前；早已2. since ，from 和 for (1)from 是介词，后接名词、动名词，表示事情的开始点，以from 短语作状语时，句中的谓语动词可用一般现在、过去和将来时，如：这个电影在晚上8 点到 10 点上映。 _ They chatted at the meeting from beginning to end 他们
7、在会议上自始至终都在聊天。(2)since 则为介词或从属连接词，其后接名词、动名词或从句，表示从某一特定时间起直至现在或过去某一特定时间为止，依然继续着的事情的开始点，在以此为时间状语的句子中，谓语动词常用完成时。如：自他们来这儿以后， 发生了许多事情。 _ The teacher said that John had made great progress since last semester老师说从上个学期以来约翰取得了很大的进步。(3)for 是介词，后接名词，可以用来计算持续的时间，表示事情从开始到结束所持续的时间，谓语动词常用过去时或完成时，for 与一般现在时连用，表示时间一直
8、持续到将来。如：The meeting lasted for hours. 会议持续了几个小时。我学过三年钢琴。_ 我认识她已经五年了。_ 3. favorite 作名词，指 “ 最爱的物品 ” ，favorite 也可作形容词，作形容词比较级和最高级形式。例如：My favorite food is dumpling我最喜欢的食物是饺子。4. stop表示 “ 停止，结束，阻止”The light turned red I have to stop 红灯亮了，我不得不停下来。(1)stop 作名词，意为 “ 车站，站点 ” 。例如：I get off at the next bus stop
9、 我在下一站下车。(2)stop 作动词，意为 “ 停止 ” ，常用于stop doing sth.结构中，表示“ 停止做某事 ” ，指停止正在做的事。例如：The students stop talking 学生停止了讲话。(动名词 talking 作宾语 ) (3)stop to do sth. 则表示 “ 停下来去做某事” ，指停止原来的事去做另外一件事。例如：The students stop to talk学生们停下来(开始 )讲话。 (不定式 to talk 作目的状语 ) We should stop to have a rest我们应该停下来休息一会儿。(4)stop sb.(
