教学的情况。1．A推理判断题。根据第一段中“90%ofteacherssaytheyarerequiredtoteachhandwriting.”可知，书法教学是基本的教学要求，故A项正确。根据“Onestudypublishedthisyearfoundthataboutthreeoutofeveryfourteacherssaytheyarenotpreparedtoteachhandwriting.”可知，很多老师不愿意教书法课，故B项错误；根据第一段的末句可知C项错误；根据全段判断，本段只是说键盘的普及使一些人认为书法渐渐过时了，故D项错误。2．D细节理解题。根据第二段可知，传统的书法教学会重复很多遍并且持续时间长，因此A、B两项内容正确。根据第三段第一句可知C项内容正确；根据最后一段第二句可知D项内容错误。3．B标题归纳题。作者叙述了美国书法教学的现状，没有发表自己的评论，故选择B。A项没有涉及，C项只是其中一部分内容，D项只是一部分人的观点。4．B观点态度题。根据全文的叙述可知，作者只是将美国书法教学的现状和不同人的观点呈现出来，并没有发表自己的见解，因此作者持客观的态度。B【文章大意】在中国电脑越来越流行，但如果人们使用电脑太多，他们可能会忘记手写笔画。在北京，几乎所有的大学生们的作业都是在电脑上做的。这样做的好处和坏处是什么呢？为了鼓励学生手写，又采取了哪些措施呢？5．B细节理解题。倒数第二段“‘Chinesecharactersenjoybothpracticalandaestheticvalue.’…”“‘Andhandwritingcontainsthewriter'semotion(情绪)’….”“…‘Throughone'shandwriting,peoplecangettoknowone'sthinkingandpersonality.’”分别对应选项A、C、D。故选B项。6．D词义猜测题。根据“…computersarebeingappliedmoreandmoreoftentomoderneducation.”“WhenI'mwritingwithapen,IfindIoftencan'trememberhowtowriteacharacter，thoughtIfeelI'mfamiliarwithit.”可知，电脑被应用于越来越多的现代教育中。当学生拿笔写字时，发现自己经常想不起来怎么去写，尽管觉得熟悉。由此可见长期依赖电脑就会这样。故选D项。7．C推理判断题。根据最后一段“Toencouragestudentstohandwrite，manyprimaryschools…”可知，为了鼓励学生手写，许多小学和大学都采取了措施。由此可推断，越来越多的学生将关注书写。故选C项。C【文章大意】本文介绍了关于机器狗对独居老人的生活是否能带来改善的一些研究报道。8．C细节理解题。从文中第一段“‘Noonewillarguethatanolderpersonisbetteroffbeingmoreactive,challenged,orstimulated(刺激)…’”可知，没有人会认为一个老人会生活得更积极、有挑战力或者更刺激。根据“‘Theproblemishowwepromotethat,especiallyforthosewithoutfriendsorhelp.’…”可知，问题就是我们如何改善那种情况，尤其对于没有朋友或者无法获得帮助的老年人。故选C项。9．D细节理解题。从文中第二段的“TheseoldpeoplewillkeepadiarytonotetheirfeelingsandactivitiesbeforeandafterAIBO.”可知，这些老人将要记日记写下在AIBO来前和后的他们的感受和活动。故选D项。10．D细节理解题。从文中第四段的“Oftentheelderlyaredisabledandcannotcareforananimalbywalkingitorplayingwithit.Aroboticdogremovesexerciseandfeedingconcerns.”可知，通常老人们是身体残疾的或不能照顾一个动物，比如遛它或者和它玩。一个机器狗不需锻炼和喂食。故选D项。11．A细节理解题。从文中最后一段的“…‘AIBOsmayevenonedayhavegamesthatcanhelpstimulateolderpeople'sminds’．”可知，AIBO有一天甚至可能有能刺激老年人头脑的游戏。故可以推测出，未来的机器狗可能能使老年人积极。故选A项。D【文章大意】本文是一篇议论文。网瘾如同吸毒。研究表明有6%～10%的人上网成瘾，本文也介绍了上网成瘾的几个典型症状。12．B细节理解题。文章开始列出的四个句子虽然表面上以第一人称作主语，但实际上是在列出上网成瘾者通常的行为。13．D细节理解题。文中出现了“…peopleworryabouttheteenagers…”这个关键的定位信息，据此可以在该段第一句找到答案。C项是对“…becausetheInternetischangingtheplayingfieldforsomeofthem.”的曲解。14．C细节理解题。列举了一位大学生上网的事，他之所以连续好几天在网吧上网正是网瘾造成的。15．A细节理解题。文章最后以设问的形式引出了一些上网成瘾的症状，所列内容相当于是一种警示：上网别上瘾。第二节【文章大意】文章主要介绍了“OK”一词的来源，专家们对此持有不同的观点。做题时需要注意段落大意和前后句的逻辑关系，还需要从文中寻找关键词。16．E根据下句“SomepeoplesayitcamefromtheNative…”可知，这里说的是“OK”一词的出处，E项“然而，语言专家们对‘OK’一词的来源持有不同的意见”符合语境，故选E。17．F根据“Someforeign­bornpeoplewrote‘allcorrect’as‘o­l­l­k­o­r­r­e­c­t’”可知，另一种观点是“OK”是“allcorrect”的一种不同拼写方法，故选F。18．B根据“Theorganizationsupported…TheycalledtheirgrouptheOKclub.”可知，这里说的是一个组织创造了“OK”一词，故选B。19．G根据“Itisaspace­ageexpression.”可知，本段前一部分介绍的是“OK”一词是随着太空时代而出现的，而最后一句说“OK”一词最早是在电话被发明的初期开始使用的。本段讲了两种不同的观点，G项起到了承上启下的作用，故选G。20．ATheseexpressions指代上句提到的短语，只有A项中提到了短语“okey­dokey”和“okey­doke”，故选A。Ⅱ.【文章大意】本文是一篇记叙文。新学期开始了，与以往不同的是，新的数学老师使用了一种特别的教学方法。老师让学生自学，遇到不会的问题时举手提问。这种方法培养了作者的探索精神，帮助作者成为班里的优秀学生之一。21．B新的数学老师坐在那里观察着“我们”。wait后跟介词for，look后跟介词at，D项不与us搭配，故选B项。22．D数学老师转着给学生分发新书，故选D项。pickup捡起，意外学会；pickout辨认出，挑出；handin上交；handout分发。23．A发完书之后，老师返回到教室前面。returntosp返回到……。故选A项。24．C根据“Wasn'thegoing
