of humors, although patients may have noticed much earlier that they weren't getting any better!

　　By the late 19th century, personality had been correctly linked to the brain. This was a big advance, but some people took it too far and phrenology （颅相学） emerged as a new 'science'.

　　Phrenologists believed that the brain affected the shape of the head, and so by feeling someone's head, they could discover the shape of their brain and therefore their personality-including, for example, how likely someone was to commit murder. At the height of its popularity, phrenologists were consulted about possible marriage partners or to give a background check on job applicants. Job interviews must have been interesting in those days!

　　More recently, scientists have looked to our genes as the source of personality. While there is certainly a link, it is far from simple. For a start, a single gene might be involved in many different aspects of our personality-and we have around 25,000 genes in our body. And when even a simple thing like the colour of your skin is the result of more than l00 different genes, imagine how many are involved in a character trait like being open, agreeable or conscientious.

【答案】Personality has long been considered related to people's nature. 2500 years ago, the ancient Greeks thought personality was linked to 'humors' in the body. In the 19th century, people thought personality had something to do with the brain, which resulted in the emergence of phrenology. More recently, genes determine personality. However, it should be much too complex.

第一段Two and a half thousand years ago, the ancient Greeks believed that your personality was the result of different fluids, or 'humors', in your body, like blood, phlegm and bile. 2500年前，古希腊人认为你的个性是体内不同体液或"体液"的结果，就像血液、粘液和胆汁一样。

第二段By the late 19th century, personality had been correctly linked to the brain. This was a big advance, but some people took it too far and phrenology emerged as a new 'science'. 到19世纪末，人格已经被正确地与大脑联系起来。这是一个很大的进步，但有些人做得太过了，颅相学成为了一门新的"科学"。

第三段简单介绍了颅相学以及流行状况。

第四段More recently, scientists have looked to our genes as the source of personality. 最近，科学家们把我们
