【正确答案】 C
【答案解析】[解析] 该空格后是a long walk作画线词的宾语，而take a walk是惯用型结构，表示去散步，而其他的动词不与walk搭配。
【正确答案】 A
【答案解析】[解析] 备选项中有than出现时看句子前半部分是否有比较结构。该空前面有一比较级的结构：larger，这就暗示句子的后面部分可能有than引出被比较的成分。
【正确答案】 A
【答案解析】[解析] 该空位于句首，在所在句中用作连词(该空与所在句之间没有逗号隔开)，再借助分句之间的句意关系判断最后的选项。从句意上看：前一句说“这座城市比我想象的要大”，而空格所在句说“商业区比我想象的要小”，因此这两句的句义有转折。
【正确答案】 C
【答案解析】[解析] 四个备选答案部可表示原因，看原文：空格后是一从句，因此空格处需要引导从句的连词。初步来说A，B和C在语法上都合适，再仔细比较这三个选项。since和as引导表原因的从句往往有一逗号与主句分开，而because的语气很强，其引导的从句不与主句分开。
【正确答案】 B
【答案解析】[解析] much of和most of分别修饰不可数名词和可数名词，原文中空格后是可教名词，所以选择most of。
【正确答案】 A
【答案解析】[解析] 四个备选答案均与open一词相关，而open既可作形容词用又可用作动词，而形容词表示状态，具有延续性。原文中白宫从10点到12点的对公众开放是属于经常性的动作，有延续性，因此选择作形容词的open。
【正确答案】 A
【答案解析】[解析] 四个备选答案均可用作副词，而只有pretty修饰副词，其他三个词均修饰动词。原文中该画线词是修饰副词的，所以选择pretty。
【正确答案】 C
【答案解析】[解析] 四个备选答案中有介词、动名词和副词。而画线词后是名词短语，画线词前是一逗号与主句隔开，因此该画线处应引导表示伴随状态的结构，所以用with。
【正确答案】 C
【答案解析】[解析] 空格前是ground(土地)，因此选择cover，表示“占据”了多大的面积。
【正确答案】 B
【答案解析】[解析] On each side是表示“每一边”。
【正确答案】 D
【答案解析】[解析] 备选答案都是连词。空格后是一从句，空格前是一名词，因此判定空格所在的从句应为定语从句或同位语从句。选择where。
【正确答案】 C
【答案解析】[解析] name after是固定的搭配，表示“根据…而命名”。
【正确答案】 A
【答案解析】[解析] cloth是布料，clothes是衣服，clothing是衣服的总称，cloths是指不同种类的料子。但该句中已经有silk限定，因此只能选A。
【正确答案】 B
【答案解析】[解析] furniture是不可数名词，因此说一件家具时，我们说a piece of furniture, pieces of furniture是家具的复数形式，其前面还可用many来修饰。
【正确答案】 D
【答案解析】[解析] 备选答案均为连词。空格前是时间名词，空格后是一从句，因此该从句应为定语从句，而when引导表时间的定语从句。
