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(shí)間點(diǎn)，可以和完成時(shí)連用。意為 ―自 ……以來 ‖，其從句為一般過去時(shí)，主句為現(xiàn)在完成時(shí)，表達(dá)主句的動(dòng)作從過去某一時(shí)刻開始一直延續(xù)到現(xiàn)在，本句的主句為現(xiàn)在完成進(jìn)行時(shí)。 【辨析】 since 與 for Since 除可作連詞、引導(dǎo)時(shí)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(shí)間，不能與一段時(shí)間，表達(dá)某一動(dòng)作延續(xù)的時(shí)間有多長(zhǎng)；既可用于現(xiàn)在完成時(shí)、現(xiàn)在完成進(jìn)行時(shí)中，也可用于一般現(xiàn)在時(shí)，一般將來時(shí)及一般過去時(shí)中。 Jack has studied Chinese in this school ________the year of 2020.
