答案A
分析:过去完成时表示“过去的过去”,即“过去某一时间之前所发生的事”,此处“by+过去时间”表示“到过去那点时间为止”,by the time后面所跟的从句,表示了time的具体时间,应该用一般过去时表示,had given是发生在by the time he wasfive之前的,要用过去完成时。(延伸)by+过去时间有下面几种情况:1)by the time+含有过去时的一个从句,如:By the time my mothercame back home,I had got the supper ready.2)by+过去的一点时间,如:By five o'clock yesterday afternoon,I had finished my homework.3)by+过去的一段时间,如:By last term we had learned two thousand words.(到上学期为止,我们已经学了二千个单词)(包括不包括上学期很模糊)4)by the end of last month(到上月底为止),by the beginning of last month(到上月初为止),by the middle of last month(到上月中为止),of后面必须跟一段时间,不能跟一点时间,不能说by the end of five o'clock,只能说by
five o'clock.5)by the age of eight(到8岁时为止)
