第二部分 英语知识运用(共两节，满分45分)
第一节 单项填空(共15小题；每小题1分，满分15分)
从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。
21．Hurry! The train ________. You know it ________ at 800 a．m..
A．leaves; leaves B．leaves; is leaving
C．is leaving; leaves D．is leaving; leaving
答案与解析：C 此题考查时态。句意：快点，火车就要开了，你知道火车上午八点准时发车。第一空表示将要发生的动作，故用现在进行时表示将来；第二空用一般现在时表示按时刻表要发生的动作或状态。
22．—I thought you were proud of the coat I ________.
—I'm afraid not. You'd better change it for another.
A．would wear B．had worn
C．wore D．wear
答案与解析：D 此题考查动词时态。本题难度较大，容易受前面时态的影响，但是要注意两点：一是前面的句子用一般过去时表示不太肯定的语气；二是后面的“你最好换一件”表明对方现在还在穿这件衣服，因此用一般现在时。
23．I'm sorry that I can not accept your ________ to attend your birthday party, Linda, because I'm ________ to answer all the customers' letters tonight by my boss.
A．requirement; required
B．demand; requested
C．request; asked
D．request; required
答案与解析：D request“请求”，此处用做名词，指有礼貌的、正式的请求；be required to do sth.相当于be asked to do sth.，强调根据事实需要提出的要求。requirement指“要求的事物”时多用复数。
24．I once thought Jonna was a good student, for she often got a high mark but ________ she was found out to often cheat in examinations.
A．actually B．truly
C．surely D．mostly
