6、ad the letter, but I dont understand it. ii. Began in the past and still continues (or has only just finished). It is often used with for + a period of time or since + a point of time (see KS 28)：动作开始于过去，现在仍在继续或刚刚结束。这时经常与 for+一段时间或 since+时间点一起使用。例如He has been there for six months (and is still there

10、型 have/has had Do 型 have/has worked2用法表示说话前某一时刻发生的动作之结果对现在的影响。例如 I have already sent him a Christmas card.我已经给他寄去了圣诞卡。 （影响是他可能不久就可以收到了。 ） She has lost her pencil box.她遗失了钢笔盒。 （影响是现在她没有铅笔盒） They have just bought a new house.他们刚买了一幢新房。 （影响是他们有新房子住了）表示不确定的过去时间状语如 already,just,yet 常用于现在完成时表示从过去某一段时间持续到说
11、话时为止的动作或状态。常与 for+时间段或 since+某时间点的时间状语连用。例如 We have learned English for about three years.我们学英语大约三年了。 They have stayed in this hotel since last Tuesday.自上星期二以来，他们一直住在这里。 He has been in the army for four years.他在部队四年了。表示从过去某一时间到说话时这一过程中动作发生次数的总和。 We have built many overpasses in the city in the past

14、续性动词：leave 平 be away(离开),borrow keep(借),buy have(买)，fall ill be ill(生病),catch a cold have a cold(患感冒),join the army be in the army(参军)2瞬时动词用于现在完成时表示动作的完成。例如He has just left. They have arrived here. The play has begun.3.瞬时动词不能与 for+时间段连用表示动作的持续性，应改用持续性动词。例如（）I have bought a calculator.（）I have bought
15、 a calculator for a week.（）I have had the calculator for a week.但瞬时动词的否定结构可以与 for+时间段连用，说明某动作不发生的状态可以持续一段时间。I havent met my tacher of English for a year.4持续性动词的现在完成时/瞬时动词的现在完成时（否定式） +sinceWe have stayed in this school since we came to the city.They havent met each other since we left school.5It is+时
16、间段 +sinceIt is two days since he left for America.6瞬时动词与持续性动词用于 till/until 结构。语法 Grammar in use1现在完成时与现在进行时现在完成时的时间概念有时是不确定的。 （cf. 第 1 册第 8388 课）我们所关心的是现存的结果，或者过去发生的事对现在的影响。现在完成时不能和明确表示过去的副词（如 ago, yesterday 等）连用。经常和现在完成时连用的副词和副词短语有：before（now） （在此以前） ；so far（到目前为止） ；up to now （直到现在） ；just（刚刚） ；alre
17、ady（已经） ；lately（最近） ；now（现在） ；疑问句和否定句中常用 ever, yet, never, not ever 等。现在进行时经常用于表示在短期内正在进行的动作或存在的情况，因此往往不需要和时间状语连用。试比较：Have you washed the dishes yet?你洗过碟子了吗？Im washing them now.我正在洗。I have just made the cakes.我刚做好这些蛋糕。I am making cakes.我在做蛋糕。I have alreay written a letter to Dan.我已经给丹写了封信。I am writt
18、ing a letter.我在写信。Henry has never been to Germany before.亨利以前从没有去过德国。He is visiting Berlin.他正在柏林观光。4现在完成时与一般过去时（1）现在完成时强调过去发生的动作的结果和对目前的影响，而一般过去时强调动作发生的时间、地点、方式等，与现在没有联系。I have just had breakfast.我刚吃过早饭I had breakfast a moment ago.我是刚才吃的早饭I have finished my homework.我已经完成作业I finished my homework in
19、the classroom after school.我是放学后在教室里完成作业的。（2）现在完成时表示的持续状态强调持续到说话时为止，与现在有联系，而一般过去时表示的持续状态强调过去某段时间的经历，与现在没有联系。The Greens have stayed in China for year.格林一家已经在中国待了一年。The Greens stayed in China for a year during the war.战争期间格林一家在中国待过一年。（3）区别现在完成时和一般过去时的关键是看句中谓语动词表示的动作或状态是否与现在有联系。现在完成时常常与包括现在时间在内的时间状语连用，
20、如 this summer,this month,today,in the past few years.比较：I have done many exercises this morning.上午我已做了许多练习。 （说话时还在上午）I did many exercises this morning.今天上午我做了许多练习。 （说话时在下午或晚上）2同位语 (Appositives)一个名词（或短语等）与另一个名词（或短语）并列而作为其说明或限定成分时称为同位语。同位语与它所补充说明的成分之间用逗号隔开。课文中有两句话含有同位语：I have just received a letter fr
21、om my brother, Tim.我刚刚收到弟弟蒂姆的来信。 （Tim 是 my brother 的同位语。它们指的是同一个人。Tim 用来补充说明 my brother 的名字）He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia.他刚买了一辆澳大利亚小汽车，现在去了澳大利亚中部的小镇艾利斯斯普林斯。 （在这句话中 a small town in the centre of Australia 是 Alice Springs 的
22、同位语，补充说明这是个多大的镇子，在什么地方）在译成汉语时，同位语或者插入主句中，或者另译为一句，很少像英语中那样用逗号隔开。请参阅课文中两个句子的译文。同位语如果太长，可以另译为一句。如课文中第二个例句的后半部分可以译为：“现在去了艾利斯斯普林斯。这是澳大利亚中部的一个小镇。 ”同位语的其他例子如：This is John, one of my best friends.这位是约翰。他是我最好的朋友之一。Mrs. Smith, my neighbour, has never been abroad.我的邻居史密斯夫人从来没有出过国。Lesson 4 An exciting trip 激动人心
23、的旅行词汇学习 Word study1receive vt.（1）接到，收到，得到：When did you receive that letter?你什么时候收到那封信的？Susan received a gift/card this morning.今天上午苏珊收到了一份礼物一张卡。receive 是“收到” ，指的是一个被动的动作，主观上接受与不接受并不清楚。take 则是主动地“拿” 、 “取”：5He told me to take the keys from his pocket.他让我从他口袋里把钥匙拿出来。I received a beautiful pen from my u

27、的复数形式。通常，number 前有 great, large, good, small, certain 等形容词，数量大小也随之改变：A large/ great number of our students are Danish.我们的学生中有许多是丹麦人。There are a small number of spelling mistakes in your homework.你的家庭作业里有少数几个拼写错误。2He will soon visit Darwin. 他不久还将到达尔文去。will 表示将来要发生的事。这句话的时态是一般将来时。 （cf. 第 12 课语法）下一句话Fr
28、om there, he will fly to Perth 也是一般将来时。3My brother has never been abroad before, so he is finding this trip very exciting. 我弟弟以前从未出过国，因此，他觉得这次旅行非常激动人心。（1）这句话由两个简单句组成，后一句由连词 so 引导，为表示结果的状语从句。（2）find 作“发现” 、 “发觉 ”讲时宾语往往带补足语（一般为形容词） ，说明宾语的状况、性质等：I find the film very interesting.我觉得这电影很有趣。She found Tons room very dirty.她发现汤姆的房间非常脏。She has already found herself wrong.她已经发现自己错了。需要注意的是，find 一词很少用于进行时态，一般用于过去时、完成时及一般现在时等。
