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。

答案：解题导语：本文通过论述电脑教育的必要性告诉我们：学生学习一些基本的电脑知识尤为重要。
1．in 解析：考查介词。电脑和网络在孩子们的教育、交流、娱乐方面发挥着越来越重要的作用。play a role in是固定用法，表示“在……方面起作用”。
2．is affected 解析：考查动词的时态和语态。现代生活的各个方面都受到电脑的影响。根据句意可知，此处应用一般现在时的被动语态。本句的主语是“Every aspect of modern life”，故此处用is affected。
3．essential 解析：考查形容词。发展数字信息读写能力在21世纪是极其重要的。此处应用形容词作表语。故填essential。
4．especially 解析：考查副词。电脑教育对学生来说特别重要。本句应用副词来修饰形容词key，故填especially。
5．to conduct 解析：考查动词不定式。be expected to do sth.表示“被期待做某事”。
6．so 解析：考查连词。本句前后表示因果关系，故用so连接两个并列句。
7．Training 解析：考查动名词。“...in basic software programs”是主语，故用动名词。
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。
