知之深,爱之切出自哪

见过钱穆先生的《国史大纲》一书中写道：“惟知之深，故爱之切”。

To Know Him Is To Love Him(知之深，爱之切)
To know know know him
Is to love love love him
Just to see him smile
Makes my life worthwhile
To know know know him
Is to love love love him
And I do
I'll be good to him
I'll bring love to him
Everyone says there'll come a day
When I'll walk alongside of him
Yes just to know him
Is to love love love him
And I do
Why can't he see
How blind can he be
Someday he will see
That he was meant for me
To know know know him
Is to love love love him
Just to see him smile
Makes my life worthwhile
To know know know him
Is to love love love him
And I do
越是了解了解了解他
越是爱恋爱恋爱恋他
仅仅看见他的浅笑
已令我没有枉度此生-
越是了解了解了解他
越是爱恋爱恋爱恋他镂
爱恋他
我想对他千般好
我欲给他挚爱真情
人们都说终有一天SPAN>
我与他能连理相结
越是了解他
越是爱恋爱恋爱恋他
