　　答案与解析

　　[语篇解读]这是一篇记叙文。Maja 在内战中失去了左腿，但她以顽强的毅力，在治疗的同时完成了中学和大学的学习，并在安装了假腿之后，在水族馆里与海豚一起畅游，终于完成了她少女时对自己逝去的堂妹的承诺：和海豚一起游泳戏水。

　　1．A下文说“Jasmina 去世之后”，由此判断本空选A表示“失去”：Maja 读二年级的时候她的堂妹 Jasmina 就去世了。

　　2．C本文最后说，“她们俩开始围绕水池一起游泳”。从文章最后的叙述判断，她此时的心愿是将来和海豚一起游泳戏水，以此来缅怀 Jasmina。因此选C。

　　3．A海豚是这两个女孩都喜欢的动物。adore 表示“非常喜欢；崇拜，爱慕”。B“收养，采纳”；C“拥有”；D“购买”都不符合句意。

　　4．B今天的 Maja 已经32岁，此时她说，“于是我决定，将来有一天，我要替她做这件事。”decide 表示“决定，认定”。

　　5．B下文说她甚至想当运动员，可见这里选B，表示她读中学的时候钟爱体育运动，甚至计划做一名运动员。四个形容词选项与语境的介词搭配的含义：A对……持肯定态度的；B对……很热情；C对……很挑剔；D对……好奇。从语境的连贯判断选B。

　　6．D语境表示转折含义，因此选D表示“不幸的是”。Maja 钟爱体育运动，可是很不幸，在1993年，在她祖国的内战中，她遭遇不幸。

　　7．A一颗炸弹使她失去了左腿。take sth.away 表示“带走，剥夺”。B“接管”；C“削减；砍倒”；D“切除，删去”。

　　8．C从故事的连贯判断选C，既然炸弹使她受伤并失去了左腿，那么后面就应该是负伤的她在美国接受治疗。

　　9．B这里用 because 引导原因状语从句：由于安装的假腿不合适，她走路的时候非常痛苦。A“直到……时候”；C“尽管”；D“假如”。

　　10．D从故事的叙述看，这里用 however 表示转折关系：假腿给她带来很多痛苦，但是尽管如此，她还是从当地的中学顺利毕业了。

　　11．B然后她拿到大学学位，在一家保险公司上班。从语境的连贯判断选B，表示“学位”。

　　12．C这里用 eventually 表示“最终，最后”：她中学毕业，然后大学毕业，找到工作，最后，开办了自己的公司。A逐渐地，慢慢地；B实际上，确实；D自然而然地。

　　13．D这里用情态动词 would 表示过去经常性、习惯性的动作：为了放松，Maja 经常会到家附近的一家水族馆观看海豚表演。

　　14．A一头叫 Winter 的海豚失去了尾巴，它吸引了 Maja 的注意力。这里用 catch one's eye 表示“吸引某人的注意力”。

　　15．D语境说 Winter 失去了尾巴，这里提到“高科技的尾巴”，从语境的连贯判断选D，她看见水族馆的训练员在给 Winter 装假尾巴。用 fit 表示“安装”。

　　16．A从语境的连贯看，看见海豚 Winter 装上假尾巴之后就能自如地在水中畅游，她联想到自己伤残的左腿，受到启发和鼓舞。inspire“鼓舞，给……以灵感”符合语境。B使……困惑；C使……震惊；D使……觉得愉悦，都不符合语境。

　　17．C她受到启发，找到 Winter 的假尾巴的发明人。然后，她有了一条新假腿，这只假腿解除了困扰她16年的痛苦。

　　18．B如今，Maja 装上的假腿使她能正常行走了，她该兑现当初对堂妹的诺言了。

　　19．D起初，这只海豚小心谨慎地接近 Maja，然后游走了。A盲目地；B生气地；C感激地；D小心地。从语境的连贯和生活常识判断选D。

　　20．C过了几分钟，这只海豚终于允许她摸一摸它的背，最后海豚 Winter 在水池中与她一起畅游。这里用 touch 表示“触摸”。

　　(2010·陕西高考)

　　Stop Spam!

　　When I first got an e­mail account ten years ago, I received communications only from family, friends, and colleagues.Now it seems that every time I check my e­mail, I have an endless series of advertisements and other correspondence that do not interest me at all.If we want e­mail to continue to be useful，we need specific laws that make spamming(发送垃圾邮件) a crime.

　　If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse.Computer programs allow spammers to send hundreds of millions of e­mails

　　almost instantly.As more and more advertisers turn to spam to sell their products, individual (个人的) e­mail boxes are often flooded with spam e­mails.Would people continue to use e­mail if they had to deal with an annoying amount of spam each time?

　　This problem is troubling for individuals and companies as well.Many spam e­mails contain computer viruses that can shut down the entire network of a company.Companies rely on e­mail for their employees to communicate with each other.Spam frequently causes failures in their local communications networks，and their employees are thus unable to communicate effectively.Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks.These computer problems raise production costs of companies, which are, in the end, passed on to the consumer.

　　For these reasons，I believe that lawmakers need to legislate(立法) against spam.Spammers should be fined，and perhaps sent to prison if they continue to disturb people.E­mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience.

　　1．What does the underlined word“correspondence”in Paragraph 1 probably mean?

　　A．messages

　　B．ideas

　　C．connections

　　D．programs

　　2．According to the text, what is the major cause of the flooding spam?

　　A．Companies rely on e­mail for communications.

　　B．More people in the world communicate by e­mail.

　　C．Many computer viruses contain spam e­mails.

　　D．More advertisers begin to promote sales through spam.

　　3．According to Paragraph 3, who is the final victim of spam?

　　A．The business.

　　B．The advertiser.

　　C．The employee.

　　D．The consumer.

　　4．What is the purpose of the text?

　　A．To inform.

　　B．To educate.

　　C．To persuade.

　　D．To instruct.

　　答案与解析

　　[语篇解读]　本文讲述的是越来越多的垃圾邮件给人们带来的麻烦，作者认为应该立法来限制垃圾邮件。

　　1．A　猜测词义题。根据句子中的advertisements可知correspondence(通信；信件)也应该是一种信息，故A选项messages正确。

　　2．D　事实细节题。从第二段第三句“As more and more advertisers turn to spam to sell their products...”可知越来越多的商人想通过发送垃圾邮件来促销产品，故D正确。

　　3．D　推理判断题。根据第三段最后一句话“These computer problems raise production costs of companies，which are，in the end，passed on to the consumer.”这些电脑问题提高了公司产品的成本，但最终转嫁到消费者身上，可知最后的受害者是消费者。

　　4．C　主旨大意题。文章主要写垃圾邮件的害处，作者呼吁立法限制垃圾邮件。文章有理有据，目的是让大家认识到垃圾邮件的害处，希望政府部门采取措施。A：通知；B：教育；C：说服；D：命令，教导。
