直到那时才.
我直到那时才逐渐认识到,知识只能来源于实践.
照理说,从句的时态要根据主句来定,但涉及到一些真理、规律性的除外.像这句话,知识来源于实践,是规律性的结论,这都要用一般时态的,所以选comes.
明白?

从句" knowledge comes only from practice"是客观真理,所以不管主句是何时态,从句都用一般现在时.
直到那时我才明白，实践出真知。
It was not until + 时间+从句。。。表示直到什么时候才怎么样。

强调句 it is 。。。that。。强调中间的部分
知识来自实践 这是真理所以用现在时态

这个好像跟时态没有太大的关系，实践出真知好像是一个熟语，所以应该是它本来的状态。

之所以选D,是因为最后的那句从句是表示一个特定的事实或者客观真理.所以必须用一般现在时comes.
例如: 太阳从东方升起, The sun rises in the east.

knowledge __comes __only from practice ，这是一个事实，对于事实或者真理等自然的规律，不管是过去还是未来还是现在，都用一般时态。

knowledge comes only from practice .知识源于实践。叙述的是一件事实，故必须得用一般现在时。It was not until then that 直到。。。才
整句话意思是：直到那时我才突然明白知识源于实践。

knowledge comes only from practice是一个事实，知识仅来自实践。所以ABC都不行，要用一般现在时。
