　　41.请选择答案填入()。
　　A.does B.makes C.covers D.gives
　　答案：C
　　解析：cover“覆盖”，在本句中指美国占据北美大陆的很大一部分面积。其他三个词都与本意无关，所以选C。
　　42.请选择答案填入()。
　　A.to B.in C.at D.from
　　答案：A
　　解析： 表示两个地区的位置有三个介词：in、to、on。in表示两者存在所属或包含的关系。(如台湾和中国的关系)，to表示两地相邻但不接壤(如中国和日本的关系)，on表示相邻且接壤(如中国和越南的关系)。因选项中没有on，就只能选to，表相邻。
　　43.请选择答案填入()。
　　A.Although B.As C.Because D.Now that
　　答案：A
　　解析： “美国是个大国”与“它不是世界上的国家”两个分句间很显然是转折的关系，所以应选although，只有它表转折。now that=since“现在，既然”，表原因。
　　44.请选择答案填入()。
　　A. every B. all C. each D. some
　　答案：C
　　解析： 本句意思是美国独立后有13个州，每个州都在美国国旗上有所表现。谓语动词是was，意味着主语是单数;这样排除了aU和some。而every一般不与of连用，所以只能选each。
　　45.请选择答案填入()。
　　A.less B.more C.another D.others
　　答案：B
　　解析： two more stars“又多了两颗星”。another表示“又，再”的时候，往往放数词之前，应说“another two stars”。
　　46.请选择答案填入()。
　　A. represents B. represented C. represent D. representing
　　答案：D
　　解析： representing the new states“代表着两个新州”，该结构是现在分词短语，修饰stars，因为stars和represent之间是主动关系，所以用现在分词来表示。
　　47.请选择答案填入()。
　　A. of B. from C. between D. by
　　答案：A
　　解析： 介词of在此处表示同位关系，即the new states就是指Alaska和Hawaii。又如：the city of Beijing北京市。
　　48.请选择答案填入()。
　　A.on B.in C.by D.for
　　答案：B
　　解析： in great numbers“大量地，大批地，成群结队地”，指人成群地来，固定搭配。
　　49.请选择答案填入()。
　　A.on B.in C.over D.of
　　答案：A
　　解析： on the coast“沿着海岸线”。coast往往和on相搭配，而不与其他介词搭配。
　　50.请选择答案填入()。
　　A.because of B.because C.for D.from
　　答案：C
　　解析： for that reason“由于那个原因”，固定搭配。又如for some reason“由于某种原因”。
