1.The vast number of new businesses the city is attracting is good news for the local economy; however, the ( ) of vacant office space is something the mayor has to figure out soon.

　　A. level

　　B. training

　　C. shortage

　　D. exaggeration

　　【答案】C。根据题意，“城市吸引的大量新企业对当地经济来说是个好消息;然而，市长必须尽快解决空置办公空间的短缺问题。”however转折连词，横线处应填入与vast number含义相反的名词，所以选择shortage。A项：水平;B项：训练;D项：夸张。

　　2.The country life he was used to ( ) greatly since the opening policy.

　　A. change

　　B. has changed

　　C. changing

　　D. having changed

　　【答案】B。The country life是整个句子的主语，定语从句he was used to是用来修饰country life，省略了关系代词that/which。所以整个句子缺谓语动词，CD选项是非谓语动词形式，因此可以排除CD。因为主语country life是单数形式，所以谓语动词要用单数形式，排除A，故答案选B。

　　3.( ) the meeting himself gave them a great deal of encouragement.

　　A. The president will attend

　　B. The president to attend

　　C. That the president attended

　　D. The president attending

　　【答案】C。( ) the meeting himself是本句主语, 句意：总统亲自出席会议给了他们很多的鼓励。这句话使用主语从句，that引导主语从句的时候，that不能省略，所以A不对，也可以用动名词的复合结构在句中作主语，B也不对，句中“the president's”为名词所有格充当动名词“attending”的逻辑主语。所以D也错了，所以选C。

　　4.If you had seen a doctor, you ( ) much better now.

　　A. are

　　B. will be

　　C. would be

　　D. would have been

　　【答案】C。考查if引导的虚拟语气。根据句子结构可知, 该句采用的是if引导的虚拟条件句, 因为主句中有now可知, 主句是对现在的虚拟。故选择C。AB不是虚拟语气的用法。D是对过去的虚拟。

　　5.It is recommended that room reservations be made ( ) in advance.

　　A. better

　　B. best

　　C. good

　　D. well

　　【答案】D。考查固定搭配。“人们建议预定房间应该早早提前”。well in advance意为”早早儿的、大大提前”，ABC选项不符合原文意思，排除。
