　　1.汉字有成千上万个，尽管其中的大多数差别很细微，且只在历史文献中出现过：“成千上万”可译为tens of thousandsof; “差别很细微”即“细微区别于”可译为slightly differentfrom;“出现过”的意思也就是“被人们看见”，因此可以译为seen,用过去分词形式表示被动。

　　2.许多现代汉字是两个或两个以上简单文字的组合：“…的组合”可译为combination of...。

　　3.汉字也可以因为其线条和点的排列组合方式被看成是一门抽象艺术：该句中 “因为其线条和点的排列组合方式”可译为由how引导的名词性从句，即because of how the characters...;“被看成是”可译为beconsidered to be, consider常构成以下词组：consider as(认为)、repeatedly consider(再三考虑)。
