　　托福阅读句子插入题：Sumer and the First Cities

　　【Paragraph 3】It used to be believed that before 3000 B.C.E. the political and economic life of the cities was　centered on their temples, but it now seems probable that the cities had secular rulers from earliest times. ■Within the　city lived administrators, craftspeople, and merchants. (Trading was important, as so many raw materials, the　semiprecious stones for the decoration of the temples, timbers for roofs, and all metals, had to be imported.) ■An　increasingly sophisticated system of administration led in about 3300 B.C.E. to the appearance of writing. ■The earliest　script was based on logograms, with a symbol being used to express a whole word. ■The logograms were incised on　damp clay tablets with a stylus with a wedge shape at its end. (The Romans called the shape cuneus and this gives the　script its name of cuneiform.) Two thousand logograms have been recorded from these early centuries of writing. A more　economical approach was to use a sign to express not a whole word but a single syllable. (To take an example: the　Sumerian word for " head” was “sag.” Whenever a word including a syllable in which the sound “sag” was to be written,　the sign for “sag" could be used to express that syllable with the remaining syllables of the word expressed by other　signs.) By 2300 B.C.E. the number of signs required had been reduced to 600, and the range of words that could be　expressed had widened. Texts dealing with economic matters predominated, as they always had done; but at this point　works of theology, literature, history, and law also appeared.(Sumer and the First Cities of the Ancient Near East)
