1.Becau 后面加 of。此处 so much viewing 相当于一个名词，故加 of。/ 删去 be。此处 may not develop 已经构成谓语动词部分，be 属于多余。/ read 改为 reading。of 为介词，后面需要接名词、代词、动名词作宾语。2.program 改为 programs。
3.noi 改为 noisy。noi 为名词，noisy 为形容词。此处应用形容词构成系表结构。4.On 改为 In。根据上下文逻辑，此处意为“在一年中”。
5.删去第二个 to。make sb.do sth.为固定搭配，意为“让某人做某事”。/ real 改为really。6.difficulty-difficulties 7.删去 in。根据句意及句子结构，此处为表语从句。/.anything 改为 everything。此处为肯定句，anything 意为“任何一件事”，侧重个体； 而 everything 意为“一切事情”，侧重整体。

No.1 In the United States there are，strict speaking，__1__ no national holiday，for each state must，through legislative enactment __2__
or executive proclamation，appoint the day which each holiday is celebrated.__3__ 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 obrvation，such as Christmas，Thanksgiving，__4__ Labor Day，Independent Day，and New Year’s Day，are uniformly t
__5__ apart by all states as legal，or public holidays.In 1968，federal legislation established __6__ Columbia Day as a legal holiday for the District of Columbia and for the federal government beginning at 1971.__7__ The law also provided begun in 1971 federal employees would be granted__8__ three-days weekends by obrving Washington’s Birthday on the third Monday in February.__9__ Memorial Day on the last Monday in May，Columbus Day on the cond Monday in October，and Veteran Day on
the forth Monday on October.By 1971，most of the states also __10__ adopted the new dates.参考答案：
1.strict改为strictly 2.holiday改为holidays。因为原句的谓语动词为复数are，所以holiday必须使用复数。另外no后面可以用复数也可以用单数。3.which前面加上on。因为先行词the day在关系从句钟做状语，还原回去应为：each holiday is celebrated on the day，所以必须加on。
4.obvation改为obrvance。obrvation意思为“观察，观测”，obrvance则表示“遵守，庆祝”。
5.Independent改为Independence。独立日的说法是“Independence Day”。
6.apart改为aside。t apart 指“使分离，使分开”，语义不同，t aside表示“留出，保留”的意思。7.at改为in 8.begun改为beginning。9.three-days 改为three-day。10.also前面加had。
No.2 黑洞 What is a black hole? Well, it is difficult to answer the question, as the terms w
e would normally u to describe a scientific phenomenon __1__ are adequate here.Astronomers and scientists think that a black hole is __2__ a region of space which matter has fallen and from which nothing can __3__ escape—not even light.But we can’t e a black hole.A black hole __4__ exerts a strong gravitational pull and yet it has no matter.It is only space—or thus we think.How can this happen? __5__ The theory is that some stars explode when their density increas to a particular point;they “collap” and sometimes a supernova occurs.The collap of a star may produce a “White Dwarf” of a “neutronstar”—
a star which matter is so den that if continually shrinks by the force of __6___ its own gravity.But if the star is very large, this process of shrinking may be so inten that a black hole results in.Imagine the earth reduced to the __7__ size of a marble, but still having the same mass and a stronger __8__ gravitational pull, and you have some ideas of the force of a black hole.__9__ And no matter near the black hole is sucked in.__10__ 参考答案： 将as 改为since或者becau。在表示原因的连接词中，as引导的原因状语从句表示已知的愿原因。将adequate 改为inadequate，或者在are后加not。从逻辑
上分析，因为我们拥有的科学术语“不充足”，所以才无法回答这个问题，所以用否定形式。在which 前加into。这是一个定语从句，意思是“黑洞是太空中物质可以掉进去的地方”，所以定语从句应该为“into which matter has fallen”。将but 改为 so。上文已提到“连光都无法从黑洞中逃出”，所以我们根本无法看到黑洞。这里应该是因果关系，而不是转折关系。5 将thus改为so。这句话的意思是“那只是空间—或者我们认为它只是空间”。so做 think 的宾语，thus 只能做连词，不能做宾语。将which 改为who。这个定语从句的意思是“它是一颗星，其密度非常大，由于自身的引力，它在不断地收缩”。matter 属于star，所以关系代词应该用who。去掉in。result为不及物动词，意为“形成了”，而“result in sth。”意为“导致某结果”。8 将mass 改为mass。mass 可指“大量的物质”，而“the mass”特指“劳动群众”，用在此处不妥。将ideas 改为idea。“idea”在表达“印象”时，为不可数名词，不可以用复数。10 将no改为any。分析便知，任何在黑洞附近的东西都会被吸进去。
