1.for → ／
在句子中说明前后两个相等成份的关系时用except，否则用except for。本句是说每位美国总统，除了乔治·华盛顿，都曾在白宫居住过，“Every American president”与“George Washington”为对等成分，故应去掉for。
2.majority → major
majority意为“大多数”、“半数以上”，一般后接复数名词，而major则为“主要的”。本句意为“华盛顿在设计白宫中起了主要作用”，故应用major。
3.of → from
要表示一个人的家乡在哪里，介词应为from。
4.long → longer
本句意思是说华盛顿把白宫设计得比原来更长，更宽了一些。与原来作比较，long当然应用比较级，而且and连接的两个形容词也应为对等成分，既然wider是比较级，long也应为比较级。
5. was ∧ first → the
the +序数词具有名词意味，在这里the first即表示the first president。
6. onto → into
“搬进新居”应为“move in”或“move into”,move on意为“继续前进”，而“move onto”则是不存在的。
7.live → living
live (a)意为“活着的”，而“living”则是“适于居住的”、“生活的”。the living area意为“适于居住的地区”。
8. so → too
原文说，战火把楼房的内部完全烧毁了，专家们说白宫太危险了，不能居住了，所以后来工人们才又重修白宫内部。“太……太……”应为“too…too…”。
9. which ∧ underground → were 或which → them
本句有两种改法，若想使这部分成为非限制性定语从句，则which引导一个句子，后面应加一个“were”；若想使这部分为独立成分，则改which为them。
10. appearing → appearance
原句意思是说，重建白宫的工作并未改变它的外貌。appearing为appear(出现)的v. + ing形式，appearance意为“外观，外貌”。
