She has been skating s she was four years old. 知識梳理 1. –How long have you been skating? 你滑多長時間了？ I’ve been skating for five hours. 我已經滑了五個小時了。 【用法】 （ 1）這是一個現(xiàn)在完成進行時的句子，現(xiàn)在完成進行時通常要和表示一段時間的狀語連用，表示在這段時間內，該動作一直在進行。其結構為 ―have/has been ++表時間段的狀語 ‖。 （ 2） for five hours 表示 ―五個小時 ‖，介詞 for 后跟時間段，表達某動作已延續(xù)多久了，故該動作應用延續(xù)性動 詞。（在肯定句中）。 （ 3） how long 意為 ―多久 ‖，在此句中，用以提問時間的長短，除此之外還可以提問物體的長度。 how long 用 以提問 ―（時間）有多久 ‖，其答語必為延續(xù)性動詞。 how long 針對動作提問的，即句中的動詞必為延續(xù)性動詞，因為只有延續(xù)性動詞才能延續(xù)一段時間，成為表狀態(tài)的形容詞或介詞短語。 How long has Elizabeth been a nurse? __________ A Since 1992 B. Seventeen years ago. C. In 199 2 ’ve been skating since I was seven years old. 【用法】此處的 since 用作連詞，后面跟時間點，可以和完成時連用。意為 ―自 ……以來 ‖，其從句為一般過去時，主句為現(xiàn)在完成時，表達主句的動作從過去某一時刻開始一直延續(xù)到現(xiàn)在，本句的主句為現(xiàn)在完成進行時。 【辨析】 since 與 for Since 除可作連詞、引導時間狀語從句外，還可做介詞，意為 ―自從 ……, 自 …… 以來 ‖，其后接具體的某一過去時間，不能與一段時間，表達某一動作延續(xù)的時間有多長；既可用于現(xiàn)在完成時、現(xiàn)在完成進行時中，也可用于一般現(xiàn)在時，一般將來時及一般過去時中。 Jack has studied Chinese in this school ________the year of 2020.
