A. had started learning B. have started learning C. started to learn D. started learning 【解析】by the time所引導(dǎo)的從句是一般過去時，其主句要用過去完成時。正確答案是A。 (2)【過去完成時與現(xiàn)在完成時的主要區(qū)別】是時間的參照點不同：過去完成時的時間參照點是某個“過去的”時間；現(xiàn)在完成時的時間參照點是“現(xiàn)在”。因此現(xiàn)在完成時中的很多規(guī)則，也適用于過去完成時。 【例句】 When I got to the cinema, the film had been on for five minutes.當我到達電影院時，電影已演了五分鐘了。(got是一個過去的“時間點”，電影“開始”在我“到達”之前，是“過去的過去”。因為for five minutes為延續(xù)一段的時間狀語，應(yīng)用可延續(xù)的系表結(jié)構(gòu)be on的過去完成時形式。） 【溫馨提示】過去完成時是一個相對的時態(tài)，表示的是“過去的過去”，只有在和過去某時或某動作相比較時才用到它，因此當原句中若找不到一個“過去的時間”作為參照點時，是不能用過去完成時的。 【例句】 He got to the railway station and suddenly realized that he had forgotten to bring his ticket.他到了火車站后忽然意識到他竟忘記帶車票了。（“忘記”這一動作在“意識到”這一動作之前。） (3)When she got to school, she realized she had left her backpack at home. 當她到學(xué)校時，她意識到她把背包忘在家里了。 表示“把某物忘在某處”要用詞組leave sth in a place。 Ive left my umbrella at home.我把傘忘在家里了。 I left my book on the desk. 我把書忘在桌子上。 forget意為“遺忘某物”，指忘記一件具體的東西，但不能有具體的地點。 【例句】 I forgot my umbrella yesterday .我昨天忘了帶傘。 Dont forget the cases. 別忘了帶箱子。 五．訓(xùn)練評價 根據(jù)提示完成單詞。 1.
