专四英语some of the most important concepts in physics______thei

选A.因为主语是concepts
owe A to B
A 归功于B
或A 归因于 B
owe...to...与attribute...to...有一个很重要的区别就是:
owe...to...的主语既可以是人,也可以是物；
而attribute...to...的主语则只能是人.另外,owe...to...只用于主动句,大都与褒义词连用.
例如：
He owes his success to his father.他把他的成功归功于他的父亲.
Jim attributes his success to hard work.吉姆把他的成功归功于努力工作.
Economists attributed the slow progress in economy to poor cooperation.经济学家把经济增长缓慢归咎于合作不好.

B

我选B
Their success owes more to good luck than to careful management.
I attribute that partly to discipline, partly to desire, and partly to the old transferability of skills.
我在字典上查了这两个句子你体会下

a
A 更幼稚归功于，认为是***功劳的意思
B则更多是属性本性引起的原因
