文档简介
现在进行时表将来现在进行时表示将来的意义,常有“意图”“安排”或“打算”的含义,这种用法的句子主语通常为人,学习时主要掌握下列三点: 一、现在进行时表示将来的用法 1表示对最近的将来确定安排。如: Gina and Cindy are meeting tonight 吉娜和辛迪今晚要会面。 They are going to Shanghai next week. 他们下个星期要去上海。 When are you starting? 你们将什么时候动身? This Sunday. 本周日。 2表示没有具体安排好细节的决定或计划。如: Im not waiting for her any longer. 我不再等她了。 When I grow up, Im joining the army. 我长大了要参军。 What are you doing for vacation? 你假期准备做什么? Im visiting my friend in Hong Kong. 我准备看望我香港的朋友。 3用在时间或条件状语从句中表示将来的动作,强调动作的持续性。如: If I am still sleeping when he comes, wake me up, please. 他来时如果我还在睡觉,请你唤醒我。 When you are passing my way, please drop in. 当你路过我家时,请进来坐坐。 二、谓语动词 现在进行时表示将来的句子的谓语动词主要有下列三种: (1)现在进行时表示将来的句子的谓语动词绝大多数是位移动词,这样的动词有arrive, come, drive, fly, go, leave, travel等。如: Im going home tonight. 我今晚回家。 Were leaving for Changsha tomorrow. 我们明天就去长沙。 (2)表示位置的动词如stay, remain和动词do与have(吃、喝)。如: What are you doing next Saturday? 下星期六你准备做什么? Im staying at home 我将呆在家里。 What are you doing this evening? 今天晚上你准备做什么? Im having dinner at home with my families. 我要与我的家人在家共进晚餐。 (3)一些其它动词。如: My mother is buying me a dictionary soon. 1我妈妈不久将给我买一本词典。 Im meeting you after school. 放学后我要找你。 三、注意点 1.现在进行时表示将来时通常与表示将来的时间状语连用,否则容易与表示“现在”或“现阶段”意义的用法相混淆。如: Tom is coming here next week. 汤姆下周要来这儿。 Im taking an exam in October 我将在10月份参加考试。 2.用这种进行时与对方讲话时可变成命令,不过语气较温和。如: What are you doing tomorrow? 你明天准备做什么? Im leaving for Shanghai. 我要去上海。 Youre staying. 你留下来吧。 What are you doing this Saturday? 你星期六准备做什么? Ive no idea. 我不知道。 Youre taking part in the sports meeting. 你参加运动会吧。 3.这种表示将来的用法不能用通常没有进行时的动词,它们只能用其它方式表示将来。这样的动词有:(1)表示状态的be动词。(2) 感官动词feel, hear, smell, see等。(3)表示思想状态的如believe, forget, know, remember等动词。(4)表示喜怒憎恶的如like, hate, love, prefer等动词。(5)表示要求,愿望的如hope, want, wish, wonder等动词。(6)表示所属关系的如belong to, have等动词。(7 )其它一些动词如appear, fit, matter, seem等。如: Are you free tomorrow? 你明天有空吗? There is going to be a meeting next week. 下周将有一个会议。 4大多数动词用现在进行时表示一个最近按计划或安排要进行的动作时都可用be going to结构换用,但动词go和come用现在进行时表示将来,不用于be going to结构中。如: Im flying to London tomorrow.=Im going to fly to London tomorrow. 明天我将飞往伦敦。 Are you coming tomorrow? 你明天来吗? Yes, Im coming. 是的,我明天来。 What are you doing for your vacation? 你假期准备做什么? Im going to Tibet for a week. 我准备去西藏一周。 1现在进行时的被动语态现在进行时的被动语态表示“某人或某事正在被”,强调主语是动作的承受者。现在进行时的被动语态由“be being及物动词的过去分词”构成,助动词be有人称和数的变化(am, is are ).Modern cell phones are being used as cameras and radios, and to send e-mail or surf the Internet.现代的手机正用照相机、收音机,并用来发送电子邮件或上网浏览。New functions are being added to the cell phones.新的功能正在往手机上添加。Is a computer center being built for the students?学生计算机中心正在建设吗?The letter is not being written.那封信没在写。现在进行时被动语态常用于以下几种情况:1.表示现在此刻正在进行的被动动作。Theprojectisbeingdiscussedatthemeeting.Anewfilmisbeingshowninthetheater.Myhouseisbeingpaintednow.2.表示现阶段正在进行的被动动作,但此动作不一定在此时此刻发生。Anewstationisbeingbuilt.Manyinterestingexperiencesarebeingcarriedoutthesedays.Amodernschoolisbeingbuiltinourhometown.3.表示经常的被动行为,常和always,often,constantly等词连用。,往往带有赞扬、责备、厌烦及埋怨等感情色彩。Heisalwaysbeingpraisedbytheteacher.The window of our classroom is often being broken.4.与部分情态动词连用,表示对正在发生的动作的推测。Hemaybebeingbeatenbyhisfatherattheverymoment.John is not here .
