Are some people born clever,and others born stupid?Or is intelligence developed by our environment and our experience?Strangely enough,the answer to these questions is yes.To some extent our intelligence is given to us at birth,and no amount of education can make a genius out of a child born with low intelligence.On the other hand,a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings.Thus the limits of person's intelligence are fixed at birth,whether or not he reaches those limits will depend on his environment.This view,now held by most experts,can be supported in a number of ways.
　　It is easy to show that intelligence is to some extent something we are born with.The closer the blood relationship between two people,the closer they are likely to be intelligent.Thus if we take two unrelated people at random from population,it is likely that their degree of intelligence will be completely different.If,on the other hand,we take two identical twins,they will very likely to be as intelligent as each other.Relations like brothers and sisters,parents and children,usually have similar intelligence,and this clearly suggests that intelligence depends on birth.
　　Imagine now that we take two identical twins and put them in different environments.We might send one,for example,to a university and the other to a factory where the work is boring.We would soon find differences in intelligence developing,and this indicates that environment as well as birth plays a part.This conclusion is also suggested by the fact that people who live in close contact with each other,but who are not related at all are likely to have similar degree of intelligence.

看了这篇文章,很受启发,下面是译文.
有些人生来就是聪明的,而另一些人生来就是愚蠢的吗?或者智力的提升是来自环境和我们的经验吗?很奇怪的是,这些问题的答案是“是”.在某种程度上,我们的智力是生来就有的,一个生来智力低下的小孩接受再好的教育,也无法成为天才.在另一方面,一直在出生地长大的小孩智力发育要低于生活环境丰富多变的小孩.因而人在出生时的智力发展程度是固定的,他能不能达到这个极限则要看他的生长环境.现在大多数专家都从不同侧面支持这一观点.
我们生来就拥有某种程度上的智力,要证明这一点很容易.两个人之间的血缘关系越近,他们的智力程度也越接近.因而如果我们从茫茫人海中随意找两个不相关的人,可能他们的智力程度就完全不同.在另一方面,如果我们找两个双胞胎,他们的智力就会差不多在同一个水平.人际关系如兄弟姐妹、父子等通常会有相同的智力水平,这一点就明显的意味着智力来源于出生.
假设我们把一对双胞胎放在不同的环境中生长,比如,我们把一个送入大学,而另一个送到车间,我们就会很快发现智力发展的不一致,这就证明环境在智力发展中也起着一定作用.这也从另一个侧面证实相互密切接触、但毫无关联的人也会有相同的智力程度.
