試題分析:考察時(shí)態(tài)。本句中的關(guān)鍵詞是by到…時(shí)為止;該詞與完成時(shí)連用。本句中by后面接的時(shí)間狀語(yǔ)是I got to the office這是一個(gè)過去時(shí)的時(shí)間,故使用過去我才是。句意:到外面來的辦公室的時(shí)候,會(huì)議已經(jīng)開始了。故A正確。
點(diǎn)評(píng):連詞by到…時(shí)為止;該詞經(jīng)常與完成時(shí)連用,如果后面是現(xiàn)在的時(shí)間,句中就使用現(xiàn)在完成時(shí);如果后面是過去的時(shí)間,就使用過去完成時(shí);如果后面是將來的時(shí)間,就使用將來完成時(shí)。
