Question

.when i was four years old ,i went to a kindergarten. the teachers taught us many interesting

songs and games. we played all day long, (i did not know what learning was at that time ,while i was learning every day.) 请说说括号内的句子是什么语法,并译成中文.

Answer 1

what learning was 是个宾语从句，做know的宾语，

翻译是：虽然我每天都在学习，但那时我不知道什么是学习（也就是不懂学习的真正意义）。
