Really?A. had started learning B. have started learning C. started to learn D. started learning 【解析】by the time所引导的从句是一般过去时，其主句要用过去完成时。正确答案是A。(2)【过去完成时与现在完成时的主要区别】是时间的参照点不同：过去完成时的时间参照点是某个“过去的”时间；现在完成时的时间参照点是“现在”。因此现在完成时中的很多规则，也适用于过去完成时。【例句】When I got to the cinema, the film had been on for five minutes.当我到达电影院时，电影已演了五分钟了。(got是一个过去的“时间点”，电影“开始”在我“到达”之前，是“过去的过去”。因为for five minutes为延续一段的时间状语，应用可延续的系表结构be on的过去完成时形式。）【温馨提示】过去完成时是一个相对的时态，表示的是“过去的过去”，只有在和过去某时或某动作相比较时才用到它，因此当原句中若找不到一个“过去的时间”作为参照点时，是不能用过去完成时的。【例句】He got to the railway station and suddenly realized that he had forgotten to bring his ticket.他到了火车站后忽然意识到他竟忘记带车票了。（“忘记”这一动作在“意识到”这一动作之前。）(3)When she got to school, she realized she had left her backpack at home. 当她到学校时，她意识到她把背包忘在家里了。表示“把某物忘在某处”要用词组leave sth in a place。Ive left my umbrella at home.我把伞忘在家里了。I left my book on the desk. 我把书忘在桌子上。forget意为“遗忘某物”，指忘记一件具体的东西，但不能有具体的地点。【例句】I forgot my umbrella yesterday .我昨天忘了带伞。Dont forget the cases. 别忘了带箱子。五训练评价 根据提示完成单词。1.
