Unit 23 Conflict.阅读理解(共15小题；每小题2分，满分30分)AA failed plot to kill Barack Obama，uncovered by US federal agents recently，has reminded people of the ideas that some humans associate with simple numbers.Two white American NeoNazi racists(新纳粹种族主义者)had planned to kill 88 African Americans，before finally assassinating(暗杀) Obama.The number “88” is equated with “HH”， initials(首字母) for the Nazi greeting, “Heil Hitler”“H” is the eighth letter of the alphabet.Many people were not familiar with the NeoNazi importance of 88，but associations attached to other numbers are more wellknown，if not always believed.The number 13，for instance，is considered deeply unlucky.In the US，many buildings do not have a floor numbered 13.They instead label it 12A，or use the letter M，which is the 13th letter in the English alphabet.New Yorks John FKennedy International airport does not have a gate number 13.And the popular Irish flight carrier, Ryan Air, has banished(摒弃) row 13 from all its planes.Last year when Brussels Airline put 13 dots in their new logo，the flood of complaints was so vast that the airline was forced to change their “unlucky logo” and add an additional dot.The fear comes from a Bible story，which states that Judas Iscariot，the disciple(门徒)who betrayed(出卖) Jesus, was the 13th to sit at the table in the Last Supper.But the most fascinating fear of the number relates to Friday the 13th.Its a day of double bad luck.In the US，many people would not schedule a wedding for Friday the 13th.According to the Stress Management Center and Phobia Institute in the US，an estimated 17 to 21 million Americans are affected by a fear of this day.【语篇解读】本文通过一个刺杀总统奥巴马未遂的谋杀，介绍了人与数字的联系。1From the first two paragraphs, we can know that _.Aa lot of Americans want to kill Barack ObamaBthe number 88 is equated with 13Cthere are still racists in the USDthe two white Americans had killed 88 African Americans before killing Barack Obama【解析】细节理解题。由第二段可知在美国仍有新纳粹种族主义者。【答案】C2When you go aboard the Ryan Air，you will probably find that _.Arow 13 is replaced with 12 ABthere is no gate 13Cpassengers complain there is 13 dots on its logoDnone of their planes have row 13【解析】细节理解题。由第四段中的“And the popular Irish flight carrier，Ryan Air，has banished(摒弃) row 13 from all its planes.”可知D项正确。【答案】D3If you are in the US，you will probably not _.Alive on the 13th floorBattend a wedding on Saturday the 14thCsee a floor numbered 3Dhave an M floor【解析】细节理解题。由第四段可知A项正确。【答案】A4From the passage，we can know that the Brussels Airline _.Adoesnt have row 13Bhas 14 dots on its logoChas no flight take off on FridaysDwas once stuck in a flood【解析】细节理解题。由第五段可知B项正确。【答案】BBCan dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight.A recent research has found a new recipe for success.According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly.Twothirds of the homes interviewed reported a positive relationship between their cat and dog.However, it wasnt all sweetness and light.There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes.One reason for this is probably that some of their body signals are just opposite.For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.In homes with cats and dogs living peacefully, researchers observed a surprising behavior.They are learning how to talk each others language.It is a surprise that cats can learn how to talk Dog， and dogs can learn how to talk CatWhats interesting is that both cats and dogs have appeared to develop their intelligence.They can learn to read each others body signals, suggesting that the two may have more in common than was previously suspected.Once familiar with each others presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa.They can easily share the same water bowl and in some cases groom (梳理) each other.The significance of this research on cats and dogs may go beyond pets to people who dont get along, including neighbors, colleagues at work, and even world superpowers.If cats and dogs can learn to get along, surely people have a good chance.【语篇解读】本文是一篇说明文，说明了狗和猫可以和平相处，它们相互学习、理解彼此的语言，通过这篇文章，人们也应该和平相处，积极打造和平世界。5Some cats and dogs may fight when _.Athey are cold to each otherBthey look away from each otherCthey misunderstand each others signalsDthey are introduced at an early age【解析】细节理解题。由第二段第四行“One reason for this is probably that some of their body signals are just oppos
