3、n government has been spending some $ 200 billion yearly for war preparations.杜鲁门政府一直每年花2000亿美元用于战备。现在完成进行时有时表示根据直接或间接的证据得出的结论：She is very tired.

The baby is sleeping.安静，孩子在睡觉。He is teaching in a middle school.他在一所中学教书。(目前阶段在进行的动作)四.现在进行时表将来摘自英语语法网现在进行时表将来，主要表示按计划或安排要发生的动作：Im leaving tomorrow.我明天走。Theyre getting married next month.他们下个月结婚。现在进行时与一般现在时均可表示将来，区别是：用现在进行时表示将来，其计划性较强，并往往
5、暗示一种意图；而一般现在时表示将来，则其客观性较强，即通常被视为客观事实，多指按时刻表或规定要发生的情况：Im not going out this evening.今晚我不准备出去。What time does the train leave?火车什么时候开?五.现在进行时表示感色彩现在进行时有时可表示满意、称赞、惊讶、厌恶等感情的色彩，通常与always, forever, constantly, continually等副词连用。比较：Shes always helping people.她老是帮助别人。(表赞扬)She always helps others.他总是帮助别人。(陈述一个
6、事实)The boy is constantly lying.这孩子老是撒谎。(表示厌恶)The boy often lies.这孩子常撒谎。(指出缺点)六.动词be的现在进行时摘自英语语法网主要用于表示一时的表现或暂时存在的状态。比较：He is foolish.他很傻。(生性如此)He is being foolish.他显得很傻。(指一时的表现，并非总是如此)He is friendly.他很友好。(长期如此)He is being friendly.他显得很友好。(指暂时的表现，而且不一定真诚)【注】“be+形容词”用于现在进行时时，其中的形容词通常只能是angry, careful,
7、 careless, clever, foolish, stupid, kind, friendly, brave, rude, polite等动态形容词，而big, tall, beautiful等静态形容词不能这样用的。现在完成进行时有哪些主要考法1.表示“持续”：即表示一个从过去某时开始一直持续的动作，这动作可能刚刚停止，也可能还在进行。如：She has been pruning the roses.她一直在修剪玫瑰。Hes been helping himself to my stationery.他未经许可一直用我的文具。The children have been having

12、完成时的区别(1)现在完成时可以表示一个已经完成的动作，而现在完成进行时则表示一个正在进行的动作：I have read the book.我读过这本书。I have been reading the book.我一直在读这本书。【注】有少数动词(如work, study, live, teach, stay等)在表示持续一时间时用这两种时态含义差不多(只是用现在完成进行进更强调动作的持续性)：How long have you worked been working here?你在这儿工作多久了？Ive lived been living here since 1988.自1988年以来我就
13、一直住在这儿。(2)现在完成时通常只陈述事实，而现在完成进行时还可表示一种感请色彩：I have waited for two hours.我等了两小时。(陈述事实)I have been waiting for two hours.我等了两个小时。(等得好辛苦)(3)现在完成进行时通常用来谈论较短暂的动作或情况，若要谈论时间延续较长的动作或情况或永久性情况，则通常用现在完成时：He has lived in Paris.他(一直)住在巴黎。He has been living in Paris.他(目前)住在巴黎。(表暂时性)(4)不用于进行时态的动词通常也不用于现在完成进行时，但它们可以用于现在完成时：Ive only known her for two day.我认识她刚刚两天。Theyve been married for twenty years.他们结婚已二十年了。The war has lasted for a long time.这场战争持续了很长时间。(5)现在完成进行时不用于被动语态，若要用可用现在完成时的被动语态代替：The house has been painted for a month.这房子已漆了一个月。The problem has been studied for five days.这个问题已研究了五天。学科网（北京）股份有限公司
