解析：
这是一篇说明文，讲述了人类脸部特征的独特性，同时谈到描绘人物性格要比描绘脸部容易一些。
3．本空后面有一个定语从句that makeone hce different fromanother使一张脸不同于另一张腔，是脸部的特征造成了这一点，选features特点．di“erences不同；parts局部，qualitles质量，都不能造成这种不同。4．前文说到小孩子，后面又列举鸽子为例，说明连动物都能识别不同的脸，这是选择后再递进，选oreven．and also，and too并且也，把人与动物并列是不对的；and then然后，转移到动物也是不对的．5．take...for granted是固定搭配，意思是“认为某事属实〞。7．所谓一个人行为、说话、思想、感觉与别人不同，是指方式的不同，选the ways。而不是manners举止，礼貌；idelis想法；patterns类型的不同。这种方式的不同使一个人不同于另一个人。8．make使得。方式cause不会“引起〞这种不同，不能选。9．人类性格是很复杂的，选complex复杂的。说到单个人可以用speclal特别的，但总的来说不能用它  opposite相反的，表示情况相反；mysterious神秘的，很片面。14．在此列举的性格都是很好的方面，选conslderate考虑周到，与其他列举的词一致。cruel残忍，与列举
词不一致；anxious着急，fond喜欢(不表示性格，只表示感情)。10．前面说到有18 000个英语单词区别人物行为的不同，也就是说我们有这些词，就掌握了情况，才有了判断HY，所以选in-formatlon情况。20．本句前面列举了一些不同术语，称呼不同人物，这些术浯就是terms。noulls指名词，含意太广泛。

In about 250 BC, the Greek scientist Archimedes was asked by King Hieron to find out if his crown was   1  gold.  Archimedes thought and thought about the problem. Suddenly the  2  came to him when he was having a  3  .
As he got into the bathtub, Archimedes   4  that if he immersed (浸人) the king's crown in a vessel   5  to the brim (边缘) with water, it would cause some water to If he then immersed a piece of pure gold of the same   7  as this crown, the same amount of water would overflow if the crown was pure gold.    8 , Archimedes found that the crown was not pure gold.
He is believed to have rushed naked (赤) from his bathtub into the  9  shouting, “Eureka! which means “I’ve  10  it!〞 Archimedes made many important scientific  11  , including pulleys, and he first explained why things float.
