　　答案：1.must　解析：考查情态动词。句意：你一定是Carol。这么多年来你一点儿没变。依据第二句可知，此处应用must表示很有把握的推测，意为“一定，肯定”，只用于肯定句。

　　2．danced　解析：考查虚拟语气。句意：Ellen是一个极出色的舞者。我希望我能够跳得和她一样好。动词wish后的宾语从句中常用虚拟语气。再根据句意可知，此处表示对现在情况的一种假设，所以从句中的谓语动词要用过去式。

　　3．would have had　解析：考查虚拟语气。句意：要不是下雨，我们的旅途会很愉快的。本句为与过去事实相反的假设，故填would have had。

　　4．made/should make　解析：考查虚拟语气。句意：我们如今都高三了。我认为我们该更加努力备战高考了。It is time＋(that)从句，that从句的谓语动词需为“动词过去式”或“should＋动词原形”。

　　5．needn't　解析：考查情态动词。句意：这周你不必请人修这台机器。到下个月我才用。根据题干中“I won't need it until next month”可推知空处表示“不必”。故填needn't。

　　6．were　解析：考查虚拟语气。根据主句中的“are talking”可知，as if引导的从句中应用与现在事实相反的虚拟语气，所以填were。

　　7．might/may　解析：考查情态动词。由语境“这样暴力的游戏不应该让小孩子玩”可推断出，“他们有可能很容易受到伤害”，故填might/may，表示“可能”。

　　8．(should) be delayed　解析：考查虚拟语气。在“It is/was proposed/suggested/decided/required that...”句型中，that后从句谓语动词用“(should)＋动词原形”。又因为the plan与delay是逻辑上的动宾关系，需用被动语态。故填(should) be delayed。

　　9．had bought　解析：考查虚拟语气。句意：——当时出售的二手车非常便宜。——我同意，要是我当时买下来就好了。if only意思是“要是……就好了”，此处表示与过去事实相反，应用过去完成时，故填had bought。

　　10．shall　解析：考查情态动词。句意：未经图书管理员允许，任何读者不得将书带出图书馆。shall用于第二、三人称表示命令、威胁、许诺、警告等语气，符合句意。

　　.单句改错

　　8．an　解析：考查冠词。用电子邮件进行交流也是一个办公标准。此处表泛指，office的读音以元音音素开头，故填不定冠词an。

　　9．which/that　解析：考查关系代词。该句是定语从句，从句中缺少主语且指物，故用关系代词which或that引导。

　　10．requirements　解析：考查名词。中学有计算机知识培训和毕业要求。句子主语为“High schools”，故此处应填名词的复数形式。
