I thought about it, and when I was four, I was already the oldest of four children, and my mother even had another child to come, so what I think she -- understandably -- really meant was that she was so ready, she was so ready.
我想了想，当我四岁的时候 我已经是四个孩子当中最大的了， 而且还有另外一个孩子在我妈的肚子里。 所以她的意思应该是，她真得很需要我能够上学了，
