II表示過去開始的動作一直延續(xù)到現(xiàn)在或者還將持續(xù)下去。 1）I have not seen Justin since Last Friday night. 2) Daniel has lived in Beijing since he came to China. III表示動作的確切時間不明確或不重要。此時下列詞匯經常和現(xiàn)在完成時連用：already, ever, never, for, just, lately/ recently, since, yet。 1） The boy has already come home. 2） I haven’t heard anything from him yet. 其中，for + 一段時間，since + 某個時間點。 e.g. We haven’t seen him for two days. We haven’t seen him since last Monday. IV表示到現(xiàn)在為止的一段時間內重復的動作。 1） Some villagers say that they have seen UFOs many times. 2） I have advised him to give up smoking many times, but he just won’t listen to me. V 現(xiàn)在完成時還可用于下列句型中： This/It is the best/ finest/ most interesting … + that- clause, This/It is the first/ second… time + that- clause, that 從句中的謂語動詞一般用現(xiàn)在完成時。 It is/ has been a period of time since + 一般過去時 1） This is the best book that I have read. 2） It is the first time that I have seen the film. 3） It is/ has been a long time since I came to Wuxi. 3、注意 1）現(xiàn)在完成時不和明確的表示時間的詞連用，如yesterday, last week, in 1976等。 2）表示短暫意義的動詞，如begin, leave, arrive, return, stop, open, go, come, die等，不能與表示一段時間的狀語連用。 * Read the following sentences and say T or F . (1) He has come to Beijing since last year. F (2) He has been here for three years. T (3) He has joined the army for three years F (4) He has been a solider for 3 years.

T 二、 現(xiàn)在完成進行時 1、 構成 have/has been doing e.g. I haven’t been sleeping well since I returned home. 2、用法 表示動作從過去開始一直延續(xù)到現(xiàn)在，可能剛剛停止，也可能仍然在進行。 1）-- Sorry, I’m late. Have you been waiting long? -- Yes. I have been waiting (wait) for an hour. 2) She is very tired. She has been working (work) all morning. 3) The man started working in the field half an hour ago. He is still working now. The man has been working (work) in the field for half an hour. 4) The boy started having dinner five minutes ago. He is still having dinner now. The boy has been having (have) dinner since five minutes ago. 3、注意 現(xiàn)在完成進行時多用持續(xù)性動詞，如do, live, learn, lie, stay, wait, stand, study等， 常和all the time, this week, this month, all night, all the morning, recently等表示現(xiàn)在之前這一段時間的狀語以及since和 for引導的時間狀語或從句連用。 e.g. He has been watching television all day. I have been learning English for three years. She’s been playing tennis since she was eight. This whole week, he has been training some new employees. He has been smoking too much recently. 三、 現(xiàn)在完成時和現(xiàn)在完成進行時的比較 1、現(xiàn)在完成時表示到現(xiàn)在為止已經完成的動作，強調結果；而現(xiàn)在完成進行時強調動作的持續(xù)性，強調“一直”，往往表示動作仍未結束。 I have been reading this novel. 我一直在讀這本小說。（書不一定看完） I have read two novels. 我已讀過兩本小說。（動作已完成） I have been writing letters. 我一直都在寫信。 I have written three letters. 我已經寫完三封信了。 2、有些動詞如study, work, live用兩種時態(tài)都可以，意思差別不大。 I have lived here since 1990. / I have been living here since 1990. They have studied the problem for quite some time. / They have been studying the problem for quite some time. 3、有些動詞動詞本身表示一種持續(xù)的狀態(tài)，一般不用現(xiàn)在完成進行時，如be, know, love, remember, understand, see, like, last。 I’ve known him for many years. They have not seen each other for a long time. The war has lasted for a long time. 動詞填空 1. How long ______ you _____________ (do) this work? (have, been waiting) 2. There you are.
