帮我检查一下这个句子对不对:Only start learn English in childhood ,can we remember words easy

only后可以用句子，或者非动词短语，所以本句中的start 不能用原形，start learn 改成starting to learn .或者像2楼那样补出主语.

easy应变成副词easily.

start后面加doing或者to do
start learning 或 start to learn。

Only when we start learning English in childhood, can we remember words easy

start 的用法有两种:start后面加doing或者to do
remember 是动词，后面用副词 easily

肯定不对撒learning，easily
