Unit 23 Conflict 阅读理解ANowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a nonspecific but stable change. For many people, the hightech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year.The genetic genie is out of the bottle.However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fastgrowing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?The statistics on population growth and hunger are disturbing. Last year the worlds population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.1.The passage mainly talks about_.A. the worlds food problemB. the development in biotechC. the genetically modified foods D. the way to solve food shortages2.According to the passage, GM foods_.A. will replace naturally grown foodsB. are far better than naturally grown foodsC. may help to solve the problem of poor nutritionD. can cause serious trouble in developing countries3.The underlined sentence “The genetic genie is out of the bottle.” in Paragraph 2 probablymeans that_.A.GM foods are available everywhereB. the technology in producing GM foods is advancedC. genetic technology may have uncontrollable powersD. genetic technology has e out of laboratories into markets4.Whats the writers attitude towards GM foods?A. Enthusiastic.B. Cautious.C. Disapproving.D. Unbelievable.【文章大意】本文是一篇说明文，主要介绍了转基因食品及其对人类生活的影响。1.C 【解析】主旨大意题。根据文章内容，特别是第一段中的“Nowadays more and more people are talking about genetically modified foods ( GM foods).”可知，本文主要介绍的是转基因食品。2.C 【解析】细节理解题。根据最后一段中的“Genetic engineering is widely used to produce plants and animals with better nutritional values.”可知，转基因食品有助于解决营养不良问题。4.B 【解析】观点态度题。根据第三段中的“However, like any new product entering the food chain, GM foods must be subjected to careful testing.”可知，作者认为转基因食品进入市场前需要严格的检测，由此可见作者对转基因食品的态度是谨慎的。B(2017湖北八校高三第一次联考)We do not usually think about how our language works.Talking is such a natural, everyday activity that we do not often stop to consider how it actually works.When we do study our language, though, we are often surprised that we are able to understand our conversations.Words can mean so many different things.However, it turns out that the speaking situation helps a lot in making language work.First, the speaking situation helps make words more particular.For example, the word “dog” can describe a dog that a speaker saw in a dream.It can also be used to discuss a neighbors dog.No language has a separate word for the idea “dog that I saw yesterday” and another word for the idea “dog that I saw in a dream”This is because the speaking situation makes it clear what speakers mean when they use words.So, when you have a conversation with your neighbor, the knowledge that you have a dog tells your neighbor what the word “dog” probably means in that situation.The speaking situation also helps make language clearer.For example, the word “bank” has two possible meanings.It can mean “a place where people keep money”，but it can also mean “the side of a river”So the sentence “I went to the bank” is not clear.It could mean I went to the side of the river or it could mean I went to the place where my money is kept.However, if the speaker is talking about fishing or going to the mountains, others probably know that “bank” means “the side of a river”The things that speakers say may not always be clear.Sometimes the words are not very particular, but the speaking situation can provide the meaning.Other times words may have many meanings.Then the speaking situation limits the right meaning.This extra knowledge from the situation is very important to understand language.【解题导语】本文讲述了语境对语言的理解起着很大作用。1The passage is mainly about _Athe best time and place to talk to others Bhow the speaking situation helps language work Cwhat to say in difficult situationsDhow our language worksB解析：主旨大意题。本文讲述了语境对语言的理解起着很大作用，故选B。2According to the passage, we can safely say that _Athe speaking situation does not affect the meaning of wordsBspeaking is not very natural for most people Cthe speaking situation is not important Dpeople often do not consider how talking works D解析：细节理解题。根据第一段中的“We do not usually think about how our language works.Talking is such a natural, everyday activity that we do not often stop to consider how it actually works.”可知，故选D。3By using the example of the word “dog”， the writer wants to show that _Aa word may need to be explained in a conversationBa word may have different meaningsCthe speaking situation helps people understand the particular meaning of a wordDthe meaning of words is not particularC解析：推理判断题。根据第二段的第一句话“First, the speaking situation helps make words more particular.”和下文的“For example”可知，下文正是用dog一词举例来论证第二段的第一句话，故选C。4According to the passage, we can know the meaning of the word “bank” by referring to _Athe time and the place where the conversation happensBthe occupation of the person who uses the wordCearlier or later parts of the conversationDa reliable dictionaryC解析：细节理解题。根据第三段所讲，作者用bank一词举例说明对话中这个词之前或之后的部分决定了这个词的含义，故选C。CThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at home with her parents. All shes ever wanted to do is to bee an elementary school teacher. However, Hipp has racked up(累计) $100,000 (about 0.67 million yuan) in student loan debt and isnt able to earn enough through working as a part-time skating instructor and restaurant server tolive anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily.The Pew Research Center recently reported that 2016 was a milestone in the evolving living arrangements of young adults in the US. Until 2016, the most mon living arrangement for young adults was to be living in their own property as part of a couple. UBS Financial Services, a Swiss global financial services pany, released a report that even suggests one reason for the growing number of young adults still living at home could be that their family doesnt want them to leave. The report shows that 74 percent of millennials(千禧一代) get some kind of financial support from their parents after college. Millennials see their parents as peers, friends and mentors(导师). In return, their parents happily provide financial support well into adulthood, helping fund everything for them. Stuart Hoffman, chief economist for the PNC Financial Group in the US, said “Although job growth for millennials since 2014 has improved, that doesnt necessarily mean that millennials are starting to fly the nest, he said. “They may like living at home and being able to save money.”He added, “While it has held back household formation and purchases on things, they are probably traveling more and eating out more. I dont know if it represents a change in moral values, its much more mon for adult children to live in their parents homes because its being part of the culture.”1.Whats the purpose of Caitlin Hipps story?A. To prove the authors view.B. To introduce her situation.C. To present the topic.D. To make readers rethink about the problem.2.What does the underlined part (Paragraph1) probably refer to?A. live with parentsB. live independentlyC. stay at homeD. leave home3.According to Hoffman, which of the following is true?A. It isnt necessary for millennials to leave the nest.B. They can spend less money on their daily life.C. Moral values are changing gradually.D. Young adults are living in a different life style.4.Whats the main idea of the passage?A. Why is the number of the millennial growing steadily?B. Why has the percentage of adults living with their parents been on the rise?C. Why are parents willing to help fund for young adults?D. Why do more adults treat their parents as peers, friends and guides?【文章大意】本文是一篇说明文，主要介绍了在美国，现在和父母同住的年轻人的数量持续增加这一社会现象。1.C 【解析】推理判断题。根据第二段中的“However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily.”可知，文章开头举Caitlin Hipp的例子就是为了引出本文话题越来越多的美国青年倾向于和父母同住。3.D 【解析】细节理解题。根据最后一段中的“its much more mon for adult children to live in their parents homes because its being part of the culture.”可知，霍夫曼认为现在的年轻人和父母同住是一种很正常的社会现象，这是不同以往的，说明年轻人的生活方式发生了变化。4.B 【解析】主旨大意题。根据文章内容，特别是第二段中的“However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily”可知，本文主要介绍了在美国，现在和父母同住的年轻人的数量持续增加这一社会现象。D(2017湖北七市高三联考)Modern humans have a hard time controlling their desire to eat.Often you eat not because you are hungry, but because you are affected by many other things.How much you eat is strongly affected by how much those around you eat.People eating alone eat least.People eating with one other person eat 35 percent more than they do at home.People dining in a party of four eat 75 percent more.Eating with overweight friends? Youll eat more.Is your waitress overweight? Youll eat more.A wide variety of food? Youll eat more.Plates can decide how sweet dessert tastes.If people ate it off a paper plate, theyd say, “This is good.” If they ate it off a fancy silver plate, they would say, “This is the greatest cake Ive eaten in my entire life.”Your knowledge about what makes food good or bad also affects how much you eat. You tend to eat more when you think the food is good, and less when you think it is bad.So Grandmas cookies always taste better than other cookies.“Good food” even has a “health halo(光环) effect”If were eating something healthy, we feel that everything in that meal is healthy.Due to this, people often believe that a cheese cake with a salad has fewer calories(卡路里) than the cheese cake alone.Thats perhaps also why eating organic(有机的) food might turn you into an annoying guy. Your brain may use anything that makes you feel good about your own morality to excuse your immoral behaviour.Food and hunger affect your judgment too.Hungry judges give more serious sentences. Kids who dont eat breakfast behave worse than kids who eat their breakfast.People whohave low blood sugar are more likely than the average person to have trouble concentrating and controlling their unpleasant emotions.【解题导语】本文主要介绍了哪些因素会导致人们吃得更多。1What is mentioned as a cause of overeating?ASuffering from great loneliness.BBeing served by a helpful waitress.CBeing treated to high quality food.DEating with many friends.D解析：细节理解题。根据第一段的“People eating with one other person eat 35 percent more than they do at home.” 可知，和许多朋友一起吃饭是吃得多的一个原因，故D项正确。2According to the passage, an annoying person may be one who_Afinds any excuse for eating moreBis crazy about the quality of platesCpetes with others in making cookiesDteaches people to stick to moralityA解析：推理判断题。根据第一段的内容和第三段中的“Thats perhaps also.your immoral behaviour.” 可知，一个让人讨厌的人可能总会找到多吃的借口，故A项正确。3According to the passage, people are more likely to make a bad judgment when _Athey dont feel hungryBthey arent overweightCthey have low blood sugarDthey know little about foodC解析： 细节理解题。根据文章最后一段的“People who have low blood sugar are more likely than the average person to have trouble concentrating and controlling their unpleasant emotions.” 可知，低血糖的人比常人更难以集中注意力和控制自己的情绪，判断力会更差，故C项正确。4What would be the best title for the passage?AWhen Cant We Go on a Diet?BWhat Affects Eating?CHow to Make Good FoodDWhere to Find Safe FoodB解析： 标题归纳题。通读全文可知，本文的主题句是第一段的第二句“Often you eat not because you are hungry, but because you are affected by many other things.”， 结合下文内容可知，本文主要介绍影响吃饭的因素，故B项最能概括文章大意。 七选五(2017云南三校高考适应性考试)Unless you think youre the smartest, who doesnt want to be smarter?
