　　多彩的世界

　　我們周?chē)�的世界充滿(be full of)色彩：草(grass)是綠色的，天空是藍(lán)色的。如果人看不到所有這些顏色，那將是多么遺憾的事呀！但有些人對(duì)某些顏色的確是看不見(jiàn)的(blind)。

　　人類(lèi)的色盲很難解釋。在一只眼睛(a single eye)里有幾百萬(wàn)(millions of)叫做“視錐”的微小物質(zhì)。它們幫助我們?cè)诹凉?bright light)下看清并辨別顏色的差異(tell the difference between colors)。單眼中也有幾百萬(wàn)“視網(wǎng)膜桿”，但它們是用來(lái)(be used for)在天色幾乎(nearly)黑下來(lái)時(shí)看清東西的，它們?yōu)槲覀冿@示形狀(shape)而非顏色。

　　一些鳥(niǎo)和動(dòng)物的眼睛有很少(few)或沒(méi)有視錐，所以它們看不到顏色。貓和狗不能和我們一樣看清顏色。

　　一些昆蟲(chóng)甚至可以看到X射線(X-ray)�？茖W(xué)家們知道，我們周?chē)�有些其他顏色昆蟲(chóng)可以看到而我們卻無(wú)法看到。

　　人類(lèi)有最偏愛(ài)的顏色。藍(lán)色常受歡迎是因?yàn)樗�是涼爽的天空和海洋的顏色。綠色是讓我們想起草地、驟野和森林的顏色，黃色是太陽(yáng)(sun)色。另一方面，紅色是血(blood)與火(fire)的顏色，使一些人想起事故、危險(xiǎn)和流血。黑色是夜的顏色．在黑暗中(in the dark)，我們看不到周?chē)�的一切，所以我們有時(shí)害怕未知的(unknown)事物，不喜歡黑色。?
