much longer time.In the research, a team of US scientists studied the blood of 16, 000 people.Among them, some were smokers, some used to smoke, and the rest were nonsmokers.Scientists compared their genes and found that more than 7, 000 genes of smokers had changeda number that is onethird of known human genes.According to NBC News, both heart disease and cancer are caused by genetic changes.Some people may have had the changes when they were born, but most people get them in their daytoday lives while doing things like smoking.When you stop smoking, a lot of these genes will return to normal within five years.This means your body is trying to heal (治愈) itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.They can stay for as long as 30 years.Its almost like leaving a footprint on wet cement (水泥) it will always be there, even when youve walked away and when the cement becomes dry.Although the study results may make people unhappy, there is a bright side：the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.1The function of Paragraph 1 is to_Agive an exampleBarouse readers interestCmake an argumentDgive the main idea of the passage2Most genetic changes happen because of_Apeoples condition at birthBenvironmental pollutionCpeoples bad living habitsDheart disease and cancer3The underlined word “it” in Paragraph 4 refers to_Athe cementBthe footprintCthe harmful effects Dthe genetic change4Which of the following statements is true?AThe findings are the fruit of more than three years research.BThe findings have prevented more people from starting smoking.CThe findings offer evidence that a damaged gene can heal itself.DThe findings help to find cures for genetic damage caused by smoking.答案与解析这是一篇说明文。研究发现即使已经戒烟，它对基因造成的伤害还会保留很长的时间，基因变化会使人患心脏病和癌症。1B推理判断题。由第一段“New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time.”可知，新的研究发现，即使你戒烟，它对你的基因造成的损害也会在身体里停留更长的时间。以及下文通过实验说明这一问题的和具体的影响，所以第一段点明了短文的主题，同时第1段的作用也是引起读者的兴趣。故B选项正确。2C细节理解题。由第三段“Some people may have had the changes when they were born, but most people get them in their daytoday lives while doing things like smoking.”可知，有些人可能在出生时基因就已经发生了变化，但大多数人的基因变化是日常生活中如吸烟所导致的。所以大多数人的基因变化是日常生活中不良的生活习惯导致的。故C选项正确。3B词义猜测题。由第四段“Its almost like leaving a footprint on wet cement (水泥) it will always be there, even when youve walked away and when the cement becomes dry.”可知，这几乎就像在湿水泥上留下一个脚印，即使当你走了，当水泥变干的时候，它会一直在那里。所以第4段中带下划线的“it”一词是指“足迹”。故B选项正确。4D细节理解题。由最后段“the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.”可知，这项发现可以帮助科学家发明药物来治疗吸烟造成的基因损伤，或者找到方法来判断哪些人患有心脏病或癌症。所以D选项“这些发现有助于找到治疗吸烟引起的基因损伤的方法”是正确的。故D选项正确。BMy friend Jason and I wanted to do something to help other people who are less lucky and help us grow at the same time.After we decided that we would volunteer in Nepal, I did some surveys on the Internet and I found an organization called Volunteer(志愿者) Nepal and felt strongly that it was the right choice for us.While making our plans, Jason and I realized that others might like the chance to be a part of our experience.So before leaving for Nepal, we asked the people we know whether they would be interested in donating(捐赠) money or goods to Nepal Orphans Home.One friend, whose family owns a shop called Drake Supermarket, told others about it.Many people wanted to donate something.We received donations that filled 29 boxes with sporting goods, toys, coloring books, pencils, childrens books, and more, The boxes were later taken to Drakes warehouse(仓库) where I prepared them for shipment.Drake agreed to ship them to Nepal for free .The boxes had arrived at the Volunteer House when we arrived there.The next day, Jason and I opened the boxes.The children from the orphanages(孤儿院) stood in a line and were able to choose a gift.This took about an hour, but the looks on their faces and the happiness that we saw in their eyes made it one of the best days of our life.We visited the orphanages there in the following days.Being with the children at the orphanages was both sad and wonderful.Im sure that anyone who has volunteered will understand what I mean by that.My experience as a volunteer was very useful.It has changed me as a person and the way I viewed life in the past.1The writer did some surveys on the Internet probably to_Aget in touch with some studentsBdecide country to volunteerCfind some friends to volunteer with himDfind an organization for volunteers2Before leaving for Nepal, the writer_Aasked his friends to go with himBfilled 29 boxes with the things he boughtCreceived many donations from other peopleDbought many things in Drake Supermarket3What can we learn from Paragraph 4?AThe writer didnt expect the kids would love the gifts.BThe children were very happy to receive the gifts.CThe children had never received gifts from others before.DThe writer and his friend took the gifts to the orphanages.4The writer thinks that his experience as a volunteer was_Auseful BembarrassingCboring Ddisappointing答案与解析本文是一篇记叙文。文章主要讲述作者和朋友在尼泊尔做志愿者的经历。1D推理判断题。根据文章第一段最后一句的After we decided that we would volunteer in Nepal, I did some surveys on the Internet and I found an organization called

when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer.This was one more weapon for her to defeat my strange probleminability to read.In the library, I found my way into the “Childrens Room.” I sat down on the floor and pulled a few books off the shelf at random.The cover of a book caught my eye.It presented a picture of a beagle.I had recently had a beagle, the first and only animal companion I ever had as a child.He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him.I never forgot my beagle.There on the books cover was a beagle which looked identical (相同的)to my dog.I ran my fingers over the picture of the dog on the cover.My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title.Without opening the book, I borrowed it from the library for the summer.Under the shade of a bush, I started to read about Amos.I read very, very slowly with difficulty.Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home.That dog was my dog, and I was the little boy in the book.At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.My mothers call returned me to the real world.I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read.But I had read it.Books could be incredibly wonderful and I was going to read them.I never told my mother about my “miraculous” (奇迹般的) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year.And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction.The power of the words has held.1The authors mother told him to borrow a book in order to_Aencourage him to do more walkingBlet him spend a meaningful summerChelp cure him of his reading problemDmake him learn more about weapons2The book caught the authors eye because_Ait contained pretty pictures of animalsBit reminded him of his own dogChe found its title easy to understandDhe liked childrens stories very much3Why could the author manage to read the book through?AHe was forced by his mother to read it.BHe identified with the story in the book.CThe book told the story of his pet dog.DThe happy ending of the story attracted him.4What can be inferred from the last paragraph?AThe author has become a successful writer.BThe authors mother read the same book.CThe authors mother rewarded him with books.DThe author has had happy summers ever since.5Which one could be the best title of the passage?AThe Charm of a BookBMum
