17-year-old Elexis Webster grew up homeless with cruel family members and serious health problems.But Webster has got over these difficulties to become an honor student at her high school.The teen spent her childhood living in dug-outs(防空洞)，cars，and any place where her family could find shelter.She was treated cruelly by her mother，a drug user，who left her and her sister alone without food for days.Her older brother disturbed her study too many tunes.Her poor living conditions led to her becoming extremely weak，which caused her to miss school often.However，she got a 4.1 GPA in the exam，though many wouldn't expect her to have such a hard life.Surviving in the family in an environment like that，she was able to come out of it，and she knew she had to make the best of what happened to her.At 14，her mother was put in prison for leaving Webster and her sister in a car in the middle of a school day.The two girls were placed in foster care(寄養所)with a woman whom Webster still lives with.She calls her “Mema”．

“Mema”，who the teen sees as her mom，encouraged Webster as she returned school again.Even after missing three years of school，Webster was able to be excellent.Now Webster has planned to attend University of California at Los Angeles and study physics.“I got to a place where I was able to keep going and push for higher than a 4.1 and push to get into a really great college or university.I see success.I see happiness and I see peace，”she told KPIX 5.【語篇解讀】 本文是一篇記敘文。講述了一個名叫Elexis Webster的少女，在殘忍的家人和嚴重的健康問題的雙重打擊下，克服了這些困難，成了她所在高中的佼佼者。這篇文章為我們詳細記錄了她的故事。

1．Where does Webster live now most probably? A．In a car.B．In the dug-out.C．In foster care.D．At the University of California.C [推理判斷題。由文章中的“The two girls were placed in foster care(寄養所)with a woman whom Webster still lives with.”在Webster 14歲的時候，她的媽媽被捕入獄，她和妹妹被送到了寄養所，后面的“still lives with”可以讓我們推斷出，Webster現在依然居住在那里。] 2．Why was Webster's mother put into prison? A．She was always taking drugs.B．She left her daughters alone in a car.C．She stole food for her three children.D．She didn't let her children attend school.B [細節理解題。由文章中的“At 14，her mother was put in prison for leaving Webster and her sister in a car in the middle of a school day.”可以得知，她的媽媽被捕入獄是因為將她和她的妹妹獨自留在了車內。] 3．What's the future goal of Webster? A．Becoming a physics teacher.B．Earning enough money to buy a house.C．Being admitted into a really good college.D．Breaking away from her mother and brother.C [細節理解題。由文章中的“I got to a place where I was able to keep going and push for higher than a 4.1 and push to get into a really great college or university”可以得知，Webster的其中一個目標就是可以進入一所很好的大學。] 4．What do we know about Webster? A．She wouldn't believe in anyone any longer.B．She got a lot of help from her brother.C．She was brought up in a warm family.D．She got motherly love from Mema.D [推理判斷題。通過文章可以得知，Webster和妹妹在寄養所里面遇到了Mema，Webster將她看成了自己的母親，并且她鼓勵Webster重返學校，讓Webster在離開學校三年的情況下，重新變得很優秀。由此可以推斷出，Webster從Mema那里得到了母愛。] Ⅱ.閱讀七選五

There once were a goat and a donkey 1.(live)on a farm.The donkey worked the hardest so the farmer 2.(feed)it the most food.Sometimes the donkey was given more food 3.it could eat.This made the goat so jealous 4.it began plotting against(謀劃對付)the donkey.“Hey，donkey，”the goat said one day.“I think you do too much work on this farm.You carry such heavy things from morning to night.Why don't you pretend 5.(get)sick so you can take a day 6.？”The donkey thought the goat had a great idea.So the next morning，the donkey lay in the stable(畜欄)on its side with its eyes 7.(close).8.(immediate)，the farmer called the doctor.After looking at the donkey，the doctor said it needed a special 9.(medical)made from the heart of a goat.So the farmer killed 10.goat and gave the donkey medicine made from its heart.【語篇解讀】這是一篇記敘文。講述的是山羊嫉妒驢子能干活受到主人疼愛，告訴驢子讓它裝病想要陷害它，但最后山羊卻被自己的嫉妒心害了。

1．living [“There once were a goat and a donkey 1.(live)on a farm.” 主語為a goat and a donkey，與live之間為主動關系，故填living。] 2．fed [“The donkey worked the hardest so the farmer 2.(feed)it the most food.”瀏覽全文可知本文是一般過去時態，根據時態一致的原則，故填fed。] 3．than [“Sometimes the donkey was given more food 3.it could eat.”考查固定搭配“more than超過”，驢子有時候被給的食物比它能吃的還要多，故填than。] 4．that [“4.it began plotting against(謀劃對付)the donkey.”考查that的用法，that放句首可以引導主語從句，故填that。] 5．to get [“Why don't you pretend 5.(get)sick so you can take a day 6.？”考查固定搭配“pretend to do sth.假裝做某事”，故填to get。] 6．off [“Why don't you pretend 5.(get)sick so you can take a day 6.？”根據句意可推斷出此處指休假，使用固定搭配“day off休假”，故填off。] 7．closed [“So the next morning，the donkey lay in the stable(畜欄)on its side with its eyes 7.(close)．”考查with復合結構。題目中已經給出了with和一個名詞eyes，和動詞close構成被動關系，故填它的過去分詞形式，故填closed。] 8．Immediately [“8.(immediate)，the farmer called the doctor.”通過副詞形式來表示時間頻率，故填Immediately。] 9．medicine [“After looking at the donkey，the doctor said it needed a special 9.(medical)made from the heart of a goat.”special為形容詞，修飾名詞，故填medicine。] 10．his/the [“So the farmer killed 10.goat and gave the donkey medicine made from its heart.”這里既可以填the來特指山羊，也可以用his表示農夫的山羊，故填his/the。] 5

Most people watching Jeremy Lin these past two months saw Jeremy Lin，New York Knicks star;but I，watching him，saw someone else.That was my elder brother，Bob，who is athletic and energetic.He could never sit still when he was in second grade;he had to get up every now and then and run around the room.And sure enough，he grew up to be a starting player for an NCAA championship lacrosse(長曲棍球)team.He was a Nike-endorsed marathoner，too，and reached the top of Mt.Everest，unguided，in his 50s.And yet my family never watched his lacrosse games.We did watch some of his marathons，but that wasn't until he was in his 20s.When Bob was in his glory days，our Shanghainese-born parents were bent on getting him into medical school.There was a loving aspect to it: I can remember my father working through math books with him，lesson by lesson，at the big blackboard in the attic.Bob never did become a doctor，though;and neither did I．It wasn't until my younger sister came along that someone in the family finally wore a white coat.Bob today could be the fittest 58-year-old on the planet.His doctor estimates his biological age at 35；he's still big mountains in the Himalayas.And，like Jeremy Lin，he's charming.No one sees Bob without leaving with a laugh.He sometimes jokes he could be mayor of his building，and it's true.To know him is to cheer for him.And yet my parents did not cheer for him.What if my mother had sat on the sidelines with her statistics，like Jeremy Lin's mother? What if my father had played videos of athletes for my brother to watch and imitate? It's hard not to wonder.And how did Jeremy Lin's parents manage to do these remarkable things? Amy Chua，the tiger mother，recalls her immigrant father beating the kids whenever they mispronounced a Chinese word.How is it that Jeremy Lin's immigrant father in particular，Gie-Ming Lin，encouraged his son to follow such an untraditional path? 【語篇解讀】 林書豪的成功，使人們開始反思什么是最合適的教育方式。家長是應該把自己的意愿強加給孩子還是發揮孩子的特長呢？ 1．Bob's glory days were those ． A．when he was doing well in math B．when he was in second grade C．when he was made mayor of his building D．when he showed his talents in sports D [推理判斷題。根據文章一、二兩段內容可知，鮑勃20多歲時在體育方面的表現很優秀，由此可推知，鮑勃最輝煌的時期應是他在體育運動中展現他的特長的時候。] 2．From the passage we can tell that Bob is ． A．active and optimistic B．clever and determined C．brave and helpful D．considerate and independent A [細節理解題。根據第三段的第三、四、五句內容可知，鮑勃積極、樂觀，故應選A項。] 3．Which of the following statements is probably TRUE? A．Bob was always ignored by his parents.B．Bob could also have been a sports star.C．Bob's parents often watched his games.D．Nobody in the author's family was a doctor.B [推理判斷題。根據文章第一段內容可知，鮑勃曾經在體育方面的表現非常優秀，多次獲獎，若能堅持下去，他也許會成為一名體育明星，故B項正確。] 4．From the last two paragraphs we can infer that.A．parents should always study together with their children B．parents should know how to educate their children properly C．children should be punished when they do anything wrong D．children should try to live up to the hopes of their parents B [推理判斷題。在文章最后兩段中，作者用反問句暗示出家長應該給孩子正確的教育，而不是強迫他們做這做那。] Ⅱ.完形填空

(2017·安徽滁州九校聯考)In the early 1980s，one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays.My mom agreed and news of the unique gift baskets my mom was making spread like wildfire 1 throughout the neighborhood.My mom was busy throughout the holiday season，so she asked a friend to help her.When the orders continued after the holiday season for baby gifts，birthday gifts and more，it occurred to them that maybe this job could be turned into a business and they did it.My mom went into her business because she had creative ideas.She got orders and filled order.But there was no goal and no real plan.In 1991，my mom's partner got into financial trouble and there was not enough money to support either mom or her partner.So if you are led by your creativity or enthusiasm，make sure you ask yourself what you purpose to do your business is.If you don't set goals，how will you know which direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can't keep scores if you don't know what game you are playing.After my mom's partner quit，she had to abandon her business to support herself.She swore she would run a business again and do it differently the next time.However，there wasn't a “next time” for her.She passed away just after her 51st birthday.She never had someone tell her how important having a goal was，she never had a chance to be everything she could be.There are no right or wrong goals，only the ones that matter to you.Set them so that you can make progress and achieve success，whatever they may mean to you.【語篇解讀】 這是一篇論述文，以作者的母親的故事證明了目標的重要性。母親在幫鄰居做禮盒的過程中發現可以把做禮盒當作一項生意，于是在只有創意和熱情的情況下開始了第一次生意，最終因為合伙人陷入經濟困難而結束，但母親還想著開始第二次生意，卻在過完51歲生日便去世了。用母親的故事證明了：一個目標是多么的重要，只有知道自己要做什么，才有可能成功。

1．What did the writer's mom do after failing in her business? A．She found a different partner.B．She celebrated her 51st birthday.C．She planned to have a second try with different methods.D．She decided never to run a business again.C [細節理解題。根據第四段“She swore she would run a business again and do it differently the next time.”可知，在合伙人辭職后，即母親生意失敗后，母親發誓：她一定會再做一次生意，下次再做不同的事。C選項符合題意。A選項的意思是找一個不同的合伙人；B選項說慶祝她五十一歲生日；D選項說母親決定再也不做生意。都不符合題意，故選C。] 2．What can we infer from the passage? A．The writer began her business with a set goal.B．The writer's mother was a woman without creativity.C．The writer's mother died because of her failure in business.D．The writer believes having goals in mind ensured one's success.D [邏輯推斷題。由文章最后一段“ Set them so that you can make progress and achieve success，whatever they may mean to you.”可知，作者認為只有建立目標才能取得成功，但并未說他會開始自己的生意，A選項錯誤；由第二段中“My mom went into her business because she had creative ideas.”可知，媽媽是具有創造性的，B選項錯誤；由第四段可知，媽媽生意失敗后還希望開始下一次生意，媽媽并不是死于生意失敗，C選項錯誤；由最后一段“Set them so that you can make progress and achieve success，whatever they may mean to you.”可知，只有心中有目標才能成功，D選項正確，故選D。] 3．How does the writer present his point of view mainly? A．By providing examples.B．By explaining causes.C．By making comparisons.D．By listing figures.A [主旨大意題。本文主要是通過舉了母親做生意只有創造性和熱情，沒有目標而生意失敗的例子，證明了只有心中有目標才能取得成功的觀點，可見本文主要是通過舉例子的方法來證明觀點的，A正確。B.By explaining causes 通過說明原因；C.By making comparisons 通過作比較； D．By listing figures 通過列數字；都不符合題意。故選A。] Ⅱ.閱讀七選五

(2017·福州八縣高二聯考)Everyone makes mistakes.1 ．Making a mistake at work，however，can be more serious.It may cause problems for your employer and even affect the company's bottom line.Evil consequences will finally come down to you.Simply correcting your mistake and moving on may not be an option.When you make a mistake at work，your career may depend on what you do next.Admit your mistake.Tell your boss about your mistake immediately.The only exception is that you make an insignificant error that will not affect anyone.Otherwise，don't try to hide your mistake.2 ．

Present your boss with a plan to fix your mistake.When you go to your boss to admit your mistake，you must have a plan for correcting it.Present your plan clearly.Tell your boss how long it will take to carry out your plan and if there are any costs involved.Don't blame anyone else for your mistake.3 ．Encourage those who may share responsibility to follow your lead in admitting to your boss.4 ．

There's a big difference between admitting your mistake and beating yourself up about it.Take responsibility but don't blame yourself for making it，especially in public.Correct your mistake on your own time.If you have to spend extra hours at work to correct your mistake，don't expect to be paid for that time.5 ．

B Several different stories are told about the origin of Saint Valentine’s Day.One legend dates as far back as the days of the Roman Empire.According to the story, Claudius, the Emperor of Rome, wanted to increase the size of his army.He knew that it would be easier to get young men who were not married to join.Therefore he made a rule that no young man could marry until he had served a certain number of years in the army.A priest(牧師)named Valentine broke the rule and secretly married a great many young people.Finally, Claudius found out about Valentine and put the priest in prison, where he remained until his death on February 14.After his death, Valentine was made a saint(圣人), and the day of his death was named Saint Valentine’s Day.It became the custom for lovers to send each other message on this day.Now Saint Valentine’s Day is a time for people to send one another

greetings of many kinds.February 14, Valentine’s Day, is sweethearts’ day, on which people in love with each other express their tender(溫柔的)emotions.People sometimes put their love message in a heart-shaped box of chocolates, or a bunch of flowers tied with red ribbons(帶子).Words of letters may be written on the flower covered card, or something else.Whatever the form may be, the message is almost the same: “Will you be my Valentine？”

語篇解讀：本文是一篇說明文。介紹了一個關于圣瓦倫丁節傳奇故事以及如今人們慶祝圣瓦倫丁節的方式。

1．Valentine was put in prison because ________.A．he secretly got married B．he didn’t serve in the army C．he married many young people secretly D．he broke the laws 解析：選C 細節理解題。根據第二段中的“A priest(牧師)named Valentine broke the rule...”可得出答案。
