October, and Veteran Day on the forth Monday on October. By
1971, most of the states also adopted the new dates. __10__參考答案及解析:
ct改爲strictly
day改爲holidays
因爲原句的謂語動詞爲複數are，所以holiday必須使用複數。另外no後面可以用複數也可以用單數。
h前面加上on
因爲先行詞the day在關係從句鍾做狀語，還原回去應爲：each holiday is celebrated on the day，所以必須加on。
vation改爲observance
observation意思爲“觀察，觀測”，observance則表示“遵守，慶祝”。
pendent改爲Independence
獨立日的說法是“Independence Day”。
t改爲aside
set apart 指“使分離，使分開”，語義不同，set aside表示“留出，保留”的意思。
改爲in
n改爲beginning
動詞begin和分句的主語federal employees的'關係是主動的，應此要用beginning。
e-days 改爲three-day
用連字符連接起來的表示數量的名詞的前置修飾語的複數概念仍然是單數，如：
a million-pound banknote。
前面加had
