In the United States there are, strict speaking, no national __1__ holiday, for each state must, through legislative enactment or __2__ executive proclamation, appoint the day which each holiday is __3__ celebrated. Congress and the president may establish legal holidays for the District of Columbia and for federal employees throughout the states and territories; and by long custom, days that receive nationwide observation, such as Christmas, Thanksgiving, Labor __4__ Day, Independent Day, and New Year’s Day, are uniformly set __5__ apart by all states as legal, or public holidays. In 1968, federal __6__ legislation established Columbia Day as a legal holiday for the
District of Columbia and for the federal government beginning at __7__ 1971. The law also provided begun in 1971 federal employees __8__ would be granted three-days weekends by observing Washington’s __9__ Birthday on the third Monday in February, Memorial Day on the last Monday in May, Columbus Day on the second Monday in October, and Veteran Day on the forth Monday on October. By 1971, most of the states also adopted the new dates. __10__
答案：
1.strict改為strictly
2.holiday改為holidays。因?yàn)樵涞闹^語動詞為復(fù)數(shù)are，所以holiday必須使用復(fù)數(shù)。另外no后面可以用復(fù)數(shù)也可以用單數(shù)。
3.which前面加上on。因?yàn)橄刃性~the day在關(guān)系從句鐘做狀語，還原回去應(yīng)為：each holiday is celebrated on the day，所以必須加on。
4.obsevation改為observance。observation意思為“觀察，觀測”，observance則表示“遵守，慶祝”。
5.Independent改為Independence。獨(dú)立日的說法是“Independence Day”。
6.apart改為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。
7.at改為in
8.begun改為beginning。動詞begin和分句的主語federal employees的關(guān)系是主動的，應(yīng)此要用beginning。
9.three-days 改為three-day。用連字符連接起來的表示數(shù)量的名詞的前置修飾語的復(fù)數(shù)概念仍然是單數(shù)，如：a million-pound banknote。
10.also前面加had。如果一個句子里面有by引導(dǎo)的時間狀語從句則動詞一般用完成體。
