He didnt love his uncle, who was as base and unworthy as his father had been upright and honourable.
他不喜欢他的叔父，因为他的叔父卑鄙下流，不像他的父亲作风正派，受人尊敬。
1）怎么翻译的中文中为什么有“不像”两字呢？我理解不了，“不像“是否要出现否定词呢？这句话可以用not等否定词改写吗？ 如何改写呢？
2) as his father had been upright and honourable - 为什么这里用had been, 而不用was ？ 可以用was吗？ had been 和 was 语义上究竟有何区别？
3）我查了词典unworthy, 词典上列出了unworthyl of sb/sth，这里后面为什么没有of sb/sth呢？
