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．—My dog's really fat.
—You ________ have given her so much food.
A．wouldn't B．can't
C．shouldn't D．mustn't
答案与解析：C 句意：——我的狗真的肥了。——你不应该喂她那么多食物。shouldn't have done sth.表示过去不应该做某事而实际上却做了。
22．—The head teacher said we had only three days to finish the project.
—Don't worry. We have already ________ two thirds of it.
A．taken over B．got through
C．made up D．given away
答案与解析：B get through此处意为“做完；完成”，符合句意。take over“接管；接收”；make up“编造；弥补；虚构”；give away“泄漏”。
23．Only when we saw the photos about the air crash ________ how terrible it was.
A．had we known B．we had known
C．did we know D．we knew
答案与解析：C 考查倒装。句意：只有当我们看到飞机坠毁的图片时，我们才知道飞机坠毁是多么可怕的事情。“only＋状语从句”放在句首时，后面的主句用部分倒装。know是发生在see后面的动作，故排除A项。
24．If any of these symptoms ________ while you are taking the medicine, consult your doctor immediately.
A．knocks B．occurs
C．reaches D．applies
答案与解析：B 句意：在服药期间如果出现任何这样的症状，就立即去咨询医生。occur“发生”为不及物动词，符合句意。
