Unit 5MusicSection Warming up & ReadingPrereading.阅读理解AAs your mom and dad always say：practice，practice，practice！Thats how you get really good at something，and thats exactly what dancer Kaeli Ware has done for most of her 14 years.The Leesburg teen is on her first tour with the musical “Brothers of the Knight，” which opens at Warner Theatre.“Ive been dancing since I was 2 years old，” she said.“My mom is a dance teacher.At first I didnt really have a choice，but now I love it.Its what I want to do every day.”Three years ago，Kaeli was attending Harper Park Middle School in Leesburg.Then she started homeschooling in order to have more time to dance.“She works hard，” said Adrienne DellasThornton，the artistic director at Kirov Academy in Washington，where Kaeli studies.Every day except Sunday，Kaeli gets up at 6 am to go to Kirov Academy.There she dances for three hours.After that she rests，eats and does schoolwork.At 4：30 pm，she starts dancing again at the Ashburn，studio where her mother teaches.She finally gets to bed around 11：30 pm after doing more homework.“Its a lot of work，but I just keep pushing，” Kaeli said.Classical ballet (古典芭蕾舞) is a big part of Kaelis studies because，she says，ballet is the foundation for other types of dancing.But Kaeli misses doing other types of dancing，such as hiphop or tap.“Even in hiphop，you need correct posture (姿 势)，” she says.She calls the way she dances in the show “lyrical (热情的)”，in part because there are words that go with her dancing.“It is like ballet，but it is a lot more powerful.I think thats why I like it so much.”语篇解读 本文是记叙文。文章介绍了一位年轻的舞蹈演员。1The text mainly introduces_.Aa musicalBa young dancerCthe fun of dancingDthe key to success解析：主旨大意题。文章从Kaeli的巡回演出说起，介绍了她对舞蹈的热爱、学舞的艰辛、学习的舞种等。答案：B2What do we know about Kaeli according to the text?AShe left school to dance.BShe learnt dancing from her mom.CShe loved dancing at an early age.DShe danced for her moms studio.解析：细节理解题。根据文章第三段的Then she started homeschooling in order to have more time to dance可知，Kaeli为了有更多的时间练舞开始接受家庭教育。答案：A3The underlined word “It” in the last paragraph refers to“_”AtapBhiphopChome schoolingDher dancing in the show解析：篇章结构题。根据文章最后一段的she dances in the show再结合第一段的her first tour with the musical.可知，此处指代Kaeli在“Brothers of the Knight”中的舞蹈。答案：D4Kaelis success shows that_.Anothing is impossibleBpractice makes perfectCa good beginning is half doneDfailure is the mother of success解析：推理判断题。从文章首句及文中对Kaeli刻苦练习舞蹈的描述可知。答案：BBPerus Inca Indians first grew potatoes in the Andes in about 200BC.Spanish conquerors brought potatoes to Europe，and colonists (殖民者) brought them to America.Today，Americans eat about 140 pounds of potatoes per person every year while Europeans eat twice as many.One of the favorite ways to eat potatoes is in the form of potato chips.While Benjamin Franklin was the US ambassador (大使) to France，he went to a big party where potatoes were prepared in 20 different ways.Thomas Jefferson，who succeeded (接替) Franklin as French ambassador，brought the recipe for thickcut，Frenchfried potatoes to America.He served French fries to guests at the White House in 1802 and at his home，Monticello.On August 24,1853，at Moon Lake Lodge in Saratoga，New York，a nativeAmerican chef named George Crum created the first potato chips.He became angry when a diner complained that his French fries were too thick，so he cut the potatoes as thinly as possible，making them too thin and crisp to eat with a fork.The diner loved them，and potato chips were born.In 1860 Chef Crum opened his own restaurant and offered a basket of potato chips on every table.In the 1950s，in Ireland，Joe “Spud” Murphy and Seamus Burke，produced the worlds first seasoned (调味的) crisps，Cheese & Onion and Salt & Vinegar.In the United Kingdom and Ireland，crisps are what people in the US call potato chips while chips refer to French fries.Ketchup flavored chips are popular in the MidEast and Canada.Seaweed is popular in Asia，and Mexicans like chicken flavored chips.About 27 pounds of potato chips are produced from 100 pounds of potatoes.Americans eat 24 billion pounds of potato chips every year，and spend more than $7 billion a year on them.语篇解读本文是说明文。文章主要介绍了薯片的历史及其现状。5What can we learn from the first paragraph?AIt was Americans who discovered potatoes.BPotatoes were first grown in the Andes of Peru.C.Europeans eat fewer potatoes than Americans.DPotatoes grow better in America than in Europe.解析：细节理解题。根据第一段的Perus Inca Indians first grew potatoes in the Andes in about 200 BC可知，土豆最初生长在秘鲁的安第斯山脉。答案：B6The author introduces the birth of potato chips by_.Ausing numbers Bmaking comparisonsC.following the order of timeDfollowing the order of importance解析：写作手法题。根据第二、三、四段出现的1802,1853,1860,1950s可知，作者按时间顺序介绍了薯片发明的过程。答案：C7What are potato chips called in the United
