現(xiàn)在完成進(jìn)行時例題解析

      一、結(jié)構(gòu)形式 

　　現(xiàn)在完成進(jìn)行時是由“助動詞have(has) + been+動詞的現(xiàn)在分詞”構(gòu)成。

　　二、基本用法

　　1. 表示從過去某時開始一直延續(xù)到說話時還在進(jìn)行，或可能還要繼續(xù)下去的動作。它通常和“for+段時間”或“since+點(diǎn)時間(也可以是從句)”的時間狀語連用。例如：

　　I have been waiting for a letter from my parents.　我一直在等我父母的來信。

　　It has been raining for three hours. 雨已經(jīng)下了三個小時了。

　　We have been studying here since 2004. 自從2004年以來，我們一直在這里學(xué)習(xí)。

　　2. 表示從過去某時開始，一直延續(xù)到說話時刻，可能剛剛結(jié)束的動作。例如：

　　She has been sweeping the street all day. She is too tired. 她一整天都在掃大街。她太累了。

　　We have been waiting for you for two hours. We don't want to wait any longer.

　　我們已經(jīng)等你兩個小時了。不想再等了。

　　三、常用句型

　　1. 肯定句：“主語+have(has) been+動詞的現(xiàn)在分詞+其他.”例如：

　　I have been sitting here all the afternoon.　 我在這兒坐了一下午。

　　He has been collecting all kinds of stamps since he was ten years old.

　　自十歲起他就開始收集各式各樣的郵票。

　　2. 否定句：“主語+have(has) not been+動詞的現(xiàn)在分詞+其他.”例如：

　　They haven't been meeting each other for five years. 他們有五年沒見面了。

　　He hasn't been teaching here these years.　 這些年他并沒有一直在這兒教書。

　　3. 一般疑問句：“Have(Has) + 主語 + been + 動詞的現(xiàn)在分詞？”其肯定回答：“Yes, 主語 + have (has).”否定回答：“No, 主語 + haven't (hasn't).”

　　四、例題解析

　　1. Cathy is taking notes of the grammatical rules in class at Sunshine School, where she ______ English for a year.

　　A. studies    B. studied    C. is    D. has been studying

　　答案：D

　　3. --Hi, Tracy, you look tired.
