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.

　　參考答案：

　　要點：句子框架New formsas well as new subjectsmust ariseas they have in the past, giving rise to。本句難點是：有并列從句。1)主語較為復雜，為并列結構，分別是new forms和new subjects，中間用as well as連接。 2)as在這里引導了一個介詞結構(as they have in the past)，have的賓語省略了，其內容與本句主語一致。3)giving rise to分句為非限定性定語從句的從句，省略了which are。

　　譯文：同過去一樣，將來必然會出現新的思維方式和新的思維對象，給完美以新的標準。
