New forms of thought as well as new subjects for thought must arise in the future as they have in the past, giving rise to new standards of elegance.

　　結(jié)構(gòu)分析：句子主干是New forms…must arise…as they have in the past。主語(yǔ)是new forms和new subjects，后跟介詞短語(yǔ)as well as new subjects for thought，謂語(yǔ)是must arise。as在這里引導(dǎo)狀語(yǔ)從句as they have in the past，have后省略了arisen，其內(nèi)容與本句主語(yǔ)一致。giving rise to…是一個(gè)現(xiàn)在分詞短語(yǔ)做狀語(yǔ)。

　　譯文：同過(guò)去一樣，將來(lái)必然會(huì)出現(xiàn)新的思維方式和新的思維對(duì)象，給完美以新的標(biāo)準(zhǔn)。
