Playing music with other people also helps children to 44 .People who can play musical instruments always have something they can do at a 45 .( )36.A.sadness B.troubleC.pleasureD.noise( )37.A.happy B.interestingC.boringD.serious( )38.A.know B.talk C.find D.fit( )39.A.second B.twoC.thirdD.three( )40.A.closes B.improves C.has D.breaks( )nguages B.mathC.historyD.physics( )42.A.why B.when C.who D.whose( )43.A.difficult B.surprisingualD.necessary( )44.A.think more B.study harderC.work togetherD.read more( )45.A.party B.dinnerC.classD.school四、阅读理解(40分)ASome people think music isn’t funny at all.About 4% of the population is what scientists call “amusic”.People who are amusics are born without the ability to enjoy musical notes.Amusic people often cannot tell the differences between two songs.As a result, songs sound like noise to an amusic.Many amusics compare the sound of music to pieces of metal hitting each other.Life can be hard for amusics.In fact, most people cannot understand what it feels like to be an amusic.Just going to a restaurant or a shopping center can be uncomfortable or even painful.That is why many amusics have to stay away from places where there is music.However, this can result in social loneliness.“I used to hate parties,”says Margaret, a seventy-year-old woman who only recently discovered that she was an amusic.By studying people like Margaret, scientists are finally learning how to identify(辨别)this unusual condition.Scientists say that the brains of amusics are different from those who can enjoy music.The difference is complex(复杂的), and it is not connected with poor hearing.Amusics can understand other non-musical sounds well.They also have no problems understanding common speech.Scientists compare amusics to people who just can’t see certain colors.Many amusics are happy when their condition is finally diagnosed(诊断).For years, Margaret felt embarrassed about her problem.Now she knows that she is not alone.That makes it easier for her to explain.“When people invite me to a concert, I just say ‘No, thanks.I’m an amusic.’”says Margaret. ( )46.Amusics are the people who .A.like musicB.have poor listeningC.don’t like musicD.are born unable to enjoy music( )47.Life is hard for amusics mainly because .A.music seems noise for themB.people don’t understand amusicsC.amusics try to stay at places full of musicD.amusics hate parties, restaurants or shopping centers( )48.Scientists identify amusics by .A.studying different kinds of musicB.going to parties regularlyC.studying amusic peopleparing music to colors( )49.What causes amusics different from most people according to scientists?A.Their brains.B.Their poor hearing.C.Their lack of colors.D.Their problems with speech.( )50.What is the main idea of the passage?A.Amusics’strange behaviors.B.Musical ability.C.Some people’s inability to enjoy music.D.Identification and treatment of amusic.BWe know music is very important in our daily life.Do you notice music p laying at any of those places when you go somewhere? Today most stores, stations, restaurants and other places play music.You might even hear music in an office or on a farm.Scientists believe that music influences the way people behave.They think that the sound of western classical (古典的)music makes people feel richer.When a restaurant plays classical music, people spend more money on food and drinks.When the restaurant plays modern music, people spend less money.Without music, people spend even less.Scientists also believe that loud, fast music makes people eat faster.Some restaurants play fast music during their hours.This makes people eat faster and leave quickly.Restaurants can make more money in this way.Some scientists think that music makes you think and learn better.They say that music helps students to be more active.It is true that people learn better when they are relaxed.And listening to music can help you relax.The next time you hear music somewhere, be careful.It might influence the way you do things.( )51.According to the text, scientists believe that music can .A.create different feelings for usB.help us to develop good habitsC.develop our interest in moneyD.influence natural environments( )52.Western c lassical music is often considered to be .A.a sign of being slowerB.something about mannersC.a sign of being richerD.something with new styles( )53.Which type of music below can make people work faster?A.Light music. B .Rock music.C.Sweet music.D.Soft music.( )54.The habit of listening to music can make a student .A.slow in actionB.care about mannersC.fresh in mindD.worry about studies( )55.Which of the following can be the best title of the passage?A.Music in RestaurantsB.Good and Bad MusicC.Types of MusicD.Music and BehaviorC(2018枣庄)EXCITING stories are everywhere in animation movies.Little villages,wild jungles and a faraway island...Get ready for trips to these places in some new films.Name ReleasedateIntroductionKung Fu Panda 3 Jan 292018In ChinaThe chubby Panda Po is back!In the new movie Kung Fu Panda 3,Po finds the SecretPanda Village,and meets many other pandas.But not all is well.A new enemy Kaicomes.He wants to beat all the kung fu masters around China and take away theirpower.Po has to stop him.He tries to teach kung fu to other pandas,and they try tosave China.The Jungle Book April 152018In theUSThis is a story about finding one’s human nature while living in the wild.The boyMowgli grows up with a family of wolves in the jungle.A tiger thinks hu mans are badbecause they hurt him once.As a human,Mowgli finds he is no longer welcome thereand decides to leave.The boy starts his trip of self-discovery in the jungle.The Angry Birds Movie May 202018In theUSIf you played the mobile phone game Angry Birds,you must remember those colorfullittle birds with angry faces.But why on earth are they so angry?That’s the story TheAngry Birds Movie wants to tell.The birds live on an island far away from the rest of the world and they know nothingof the outside world.One day,the island meets its first visitors—the green pigs.Theyare up to something.See how the conflict between the birds and the green pigsbegan in the 3-D animated movie..A.playB.cartoonC.warD.opera( )57.In order to destroy Kai’s plan,Po tries to .A.find his father Li Shan for helpe to China to learn Kung FuC.go to his birth place to find villagers for helpD.teach villagers Kung Fu to fight against him( )58.Why does Mowgli decide to leave in The Jungle Book at last?Because .A.he doesn’t find humans’natureB.he wants to start his trip of self-discoveryC.animals don’t want to accept him any moreD.he likes living with wolves to find human’s nature( )59.From The Angry Birds Movie we can guess that .A.living on an island far away from the rest of the world may be very boringB.people who play the mobile phone game will remember the birds’angry facesC.the first visitors and the birds are up to somethingD.the birds might not get along well with the pigs in the following story.( )60.The information most probably comes from .A.a fictionB.a newspaperC.a noteD.a bookD根据短文内容,从下列七个选项中选出能填入空白处的最佳选项Giving children music lessons won’t just introduce them to a world of rhythm and melody—it could also significantly improve their language skills.61. 74 Chinese children before primary school was led by scientist Robert Desimone from MIT.In the study, the 4-to-5-year-old children were divided into three groups.One group received a 45-minutepiano lesson three times a week.While another group received extra reading instructionlessons.62.63. Then the children were tested on their ability to discriminate(辨别)words based on differences in tone(声调)and so on.The test results showed that the children who had taken piano lessons performed better at discriminating words, when compared against the children who took extra reading lessons.64.The researchers think that the musical education helped these children perform better in language tests, even better than the kids who took extra reading lessons.65. “That means schools could spend more time and energy on music and there will be improvement in children’s studies,”Desimone says.A.The research showed a result.B.The classes lasted for six months.C.The third group took no extra lessons.D.This should make educators pay close attention.E.But the two groups both did better than the third oneF.Most people think it useless to make students have music classes.G.I think that some school should give students as many activities as they can.五、词汇运用(5分)根据句意及首字母提示写单词。

三、简答题
19.阅读下面的材料，回答下列问题：
自从非典型肺炎在我国部分地区出现以来，过氧乙酸作为高效消毒剂被广泛使用。
过氧乙酸在常温下是一种无色有刺激性气味的液体，易挥发，易溶于水和醋酸。
它对呼吸道黏膜有刺激性，高含量的过氧乙酸溶液对皮肤有腐蚀性。
一般商品过氧乙酸是40%的醋酸溶液，使用前通常先用蒸馏水等将其稀释，消毒时可用喷雾法消毒，也可将其配制成0.2%的水溶液洗手消毒。
过氧乙酸不稳定，易分解生成无毒物质，若用喷雾法消毒，过氧乙酸在半小时内就可完全分解。
（1）在过氧乙酸的质量分数为40%的醋酸溶液中，溶质是，溶剂是。
（2）分别指出过氧乙酸的一点物理性质和一点化学性质。
物理性质：；
化学性质：。
（3）100 g过氧乙酸的质量分数为0.2%的洗手液中含过氧乙酸g。
（4）不慎让高含量的过氧乙酸溶液沾到皮肤上，应做怎样的处理？。
（5）根据过氧乙酸的性质，用过氧乙酸喷雾消毒过的房间，人若要进去，应注意什么？
