Answer 1

答案：
解析：

1．nineteen改为nineteenth　第十九世纪，应用序数词。 　　2．builded改为built　built为不规则动词：build, built, built。 　　3．去掉to　want后面并没有省略不定式，它的宾语应是everything。 　　4．√ 　　5．worst改为worse　此处表示比较。 　　6．but改为and　两句在逻辑关系上是顺承而非转折。 　　7．middle前加the　固定词组：in the middle of在……中间。 　　8．not前加is　although引导让步状语从句，句子中应有谓语动词。 　　9．very改为so　so…that结构中so不能换成very。 　　10．去掉back　return含义为“返回”，不再与back连用。
