What Educational Programs Are Provided by Organizations?The organizations mentioned above provide educational programs for kids,such as a community your child can be a part of and programs that focus on education,health,leadership,recreation and fitness.Another possibility is the Boy Scouts of America or the Girl Scouts.These are two separate organizationsthatcanpotentiallyprovideyourchildwithasenseofaccomplishment,self-confidence and belonging.Both organizations will provide your child with many learning experiences and activities both indoors and outdoors. What Kind of Program Is Best for My Child?The type of educational program that's best for your child is subjective and based on many试卷第2页,总10页factors,including your child's age.If your child is in primary school,educational programs can help him or her develop as a person and gain leadership skills,a sense of self-worth and the ability to cooperate with others.By the time your child is in high school, his or her involvement with educational programs and other extracurricular activates can be key elements when your child is applying to college.When you help your child to pick an educational program,carefully consider what your child needs and what every option offers.1.How should a parent choose a program that suits his child?A . Based on the child's age and needs.B . Considering what organization offers it.C . According to the child's school performance.D . Depending on the location of the program.2.What is the best program for a child according to the author?A . It must promote the child's leadership skills.B . It can contribute to applying to college.C . There is no standard answer to the question.D . There are activities a child likes best. 3.Who is this text probably written for? A . Teachers. B . Parents.C . School kids.D . Program organizers.At the age of 83,I'm reading more and dusting less.I'm sitting in the yard and admiring the view without caring about the weeds in the garden.I'm spending more time with my family and friends and less time working.Whenever possible,life should be a pattern of experiences to savor,not to suffer.I'm trying to recognize these moments now and cherish them.I’m not"saving"anything;we use our good china and crystal for every special event such as losing a pound,or the first Amaryllis blossom.I wear my good clothes to the market.I'm not saving my good perfume for special parties ,but wearing it for clerks in the hardware store and tellers at the bank.“Someday"and"one of these days"are losing their positions in my vocabulary.If it's worth seeing or hearing or doing, I want to see and do it now.I'm not sure what others would have done had they known they wouldn't be here for the tomorrow that we all take for granted.I think they would have called family members and a fewclose friends.They might have called a few former friends to apologize and mend fences for past quarrels.I like to think they would have gone out for a Chinese dinner or for whatever their favorite food was.It's those little things left undone that would make me angry if I knew my hours were limited.Angry because I hadn't written certain letters that I intended to write one of these days.Angry and sorry that I didn't tell my husband and parents often enough how much I truly love them.I'm trying very hard not to put off,hold back,or save anything that would add laughter and luster to our lives.And every morning when I open my eyes,I tell myself that it is special.Every day,every minute,every breath truly is a gift.4.What does the underlined word"savor"in paragraph 2 probably mean?A.Enjoy.B.Learn.C.Share.D.Remember.5.Why is the author not"saving"anything?A.She has already saved enough.B.She wants to seize the day.C.She finds the chance to spend.D.She attends many special occasions..6.What is the author's purpose in writing the text?A.To show her regret for what she missed in life.B.To blame people who left many things undone.C.To persuade people to think more of themselves.D.To share what she has learned from her life.7.The author would feel angry if___________.A.there were few things she could do B.she could not live longC.her last days were full of regret D.her efforts were in vainLiterature is an important part of a total language arts program at all grade levels because of the many benefits it offers.Literature provides pleasure to listeners and readers.It is a relaxing escape from daily problems,and it fills leisure moments.Making time for recreational reading and using high-quality literature help to develop enthusiastic readers and improve achievement.Developing a love of literature as a recreational activity is possibly the most important outcome of a literature program.Literature builds experience.Through reading,children expand their horizons through试卷第4页,总10页vicarious(引起共鸣的)experiences.They visit new places,gain new experiences,and meet new people.They learn about the past as well as the present and learn about a variety of cultures,including their own.They discover the common goals and similar emotions found in people of all times and places. Nory Ryan's Song by Patricia Reilly,Giff,a hard survival story,is set in Ireland during the potato hunger of I845,and Patricia Polacco's The Butterfly ,deals with Nazis,resistance,and Jewish persecution(迫害)during World War II.Literature provides a language model for those who hear and read it .Good literature exposes children to correct sentence patterns,standard story structures,and varied word usage.Children for whom English is a second language can improve their English with the interesting context,and all children benefit from new vocabulary that is woven into the stories.Literature develops thinking skills .Discussions of literature bring out reasoning related to sequence;cause and effect; character motivation; predictions;visualization of actions, characters, and settings; critical analysis of the story;and creative responses.Literature helps children deal with their problems .By finding out about the problems of others through books, children receive insights into dealing with their own problems,a process called bibliotherapy. Children might identify with Gilly,living angrily in a foster home in Katherine Paterson's The Great Gilly Hopkins ,or with Mary Alice ,a city girl forced to live with her grandma in a“hick town"in Richard Peck's A Year Down Yonder.8.What is likely to be the most significant consequence of a literature program? A . The habit of reading for pleasure. B . The lessons learned from works.C . The achievements of language skills.D . The ways of thinking developed by reading. 9.Why are Nory Ryan's Song and The Butterfly mentioned in paragraph 3? A . To introduce two great masterpieces.. B . To expand children's horizons in literature. C . To prove literature includes a variety of cultures. D . To give examples of books that provide such experiences. 10.From the last paragraph we know that literature can be___ A . educational B . practical C . changeable D . reliable11.What could be the best title of the text? A . Power of Books B . Ways of ReadingThe world's first luxury space hotel,Aurora Station,was announced Thursday at the Space 2.0 Summit in San Jose,California.Developed by US-based space technology start-up Orion Span,the space station will host six people at a time,including two crew members,for 12-day trips of space travel.It plans to welcome its first guests in 2022.“Our goal is to make space accessible to all,"Frank Bunger,CEO and founder of Orion Span,said in a statement."Upon launch,Aurora Station goes into service immediately,bringing travelers into space quickly and at a lower price point than ever seen before."While a$10 million trip is outside the budget of most people's two-week vacations,Orion Span claims to offer an authentic astronaut experience."It has taken what was historically a 24-month training to prepare travelers to visit a space station and streamlined(精简)it to three months,at a fraction(小部分)of the cost,"says Bunger.During their 12-day adventure,the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit,where they will witness incredible views of the blue planet.The hotel will orbit Earth every 90 minutes,which means guests will see around 16 sunrises and sunsets every 24 hours. Activities on board include taking part in research experiments such as growing food while in orbit,which guests can take home for a super-smug souvenir,and soaring over their hometown.Guests can have-live-video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and,upon(return to Earth will be greeted with a specially arranged hero's welcome.While enjoying the thrills of zero gravity,the travelers will be able to float freely through the hotel,taking in views of the northern and southern aurora from the station's windows.Deposits are already being accepted for future stays on the space hotel.12.what can we know about Aurora Station?A.It was set up in San Jose,California.B.It is created by an international company.C.It will host eight people at a time.D.It won't be put into operation until 2022.13.what is the purpose in building Aurora Station?A.To popularize the astronaut experience.B.To make profits through this new industry.试卷第6页,总10页C .

Here are the rules that you can also apply to make yourself work really hard. Practice working hard.17. Therefore,if you want to be a hard worker,you must practice working hard.Practice waking up early, practice doing a lot of work,and practice working more hours.One day you will wake up and realize that you are a hard worker. 18.Many hard workers always have a large purpose that forces them to work.Don't just think of buying a car or a big house because this is not a purpose strong enough to push you forward.An example of a big purpose is deciding that you are working hard so that you bring change in the lives of your friends,family,and neighborhood.A strong purpose always involves bringing a large positive change in any particular setting. Surround yourself with hard workers.19. But if you surround yourself with hardworking people,you will find yourself working hard towards your goal.Avoid friends who just want to have fun all the time.This type of friends will always discourage you when you attempt to work hard.Therefore,always surround yourself with go-getters.Read and watch inspirational materials.You can also push yourself harder through reading and watching inspirational material.Motivational books and videos encourage you to work harder.These materials make you work hard.20. A .Have a strong purpose.B .Find a great goal to overcome your laziness.C .Like other skills,one has to practice it to perfect it.D .Inspirational material makes you believe in yourself.E.Nevertheless,occasions are not rare when we always find it difficult to push ourselves harder.F.They remove discouragement and assure you that you will never fail if you push yourself to the limit.G.If you surround yourself with lazy people,you will also be lazy. 三、完形填空A woman couldn't find her wallet at Gilleece's bar.She didn't ___ about her $1500 in cash as her wedding ring was in side.Gilleece disliked the ____that a theft could have occurred.So he was ___ to help.He spent hours ____footage(影像)from security cameras and he saw a boy put something into his pocket and walk off.Gilleece ____a clip(片段)on the bar's Facebook page."I didn't want to ____ him,"he said."I just asked if anybody knew the guy was."Within hours,Gilleece got a text from 17-year-old Rivens Prather.who admitted doing it because he was ______ He said he opened the wallet and saw the ring,thinking it was fake,so he took the money and threw the wallet ___ the docks(码头)into the ocean.Gilleece told the teen to meet him at the docks where Cilleece,a father of two,saw him for what he was:more of a kid than a(n)______But the ____ were high.The police were already on the ____;Prather could be facing theft charges.I had to help him ____,"says Gilleece.He ____ two local divers to search the waters.____,a detective was waiting there.A crowd had ____ to watch the two divers search in the icy water.Hours passed,with no ___ of the ring.And then a diver _____,ring in hand.Cheers erupted from the crowd.When Gilleece called the wallet's owner,she burst into tears.

重庆市渝中区巴蜀中学2019届高三上学期第三次适应性月考语文试题解析汇报版

实用标准文案精彩文档巴蜀中学2019届高考适应性月考卷(三)语文一、现代文阅读(33分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成下列小题。

①进入21世纪后,信息通信技术出人意料地迅猛发展和广泛运用,使人类社会快速迈入信息时代,这与20世纪的工业时代形成鲜明对比。

21世纪信息时代的特点是什么?②首先,信息通信技术的广泛运用使社会经济运作模式和人类职业世界发生了深刻变化。

运用新知识、新思想和新技术实现快速产品创新和全球贸易,在人类历史上第一次成为经济发展的核心。

与此同时,伴随计算机和电子通信技术的发展,人类的许多工作正被机器代替。

人类的经济模式正快速转变为全球经济和知识经济,人类社会正快速进入知识社会。

美国经济学家写道:“主要由常规认知工作和常规手工劳动构成的工作,其份额正日益下降。

国家日益增长的劳动力比例则是那些强调专家思维或复杂交往的工作。

”当重复性的常规工作被计算机取代时,人类就必须从事计算机不能胜任的工作,也因此必须发展计算机不具备的复杂能力,即以专家思维和复杂交往能力为核心的“21世纪素养”。

这类工作以创造、发明、交往为核心,从业者也就由工业时代的“常规生产工作者”转变为信息时代的“心灵工作者”。

此外,由于科学技术的快速发展及由此导致的产品的快速创新,人类职业的变化日益加剧:旧职业快速淘汰,新职业不断涌现。

因此,未来教育不仅要为创新驱动的职业做好准备,还要为尚未诞生的职业做好准备。

在此背景下,具有广泛迁移性的核心素养成了教育的首要目标。

③其次,信息通信技术和全球化使社会生活发生深刻变革。

在信息时代,每个人都是“数字公民”,怎样合法地、道德地使用信息通信技术?在日益多元化的社会,怎样管理和化解价值观、利益等方面的冲突?在日益网络化的社会,怎样运用包括信息技术在内的各种手段发展“社会资本”“社会技能”和“跨文化素养”?这些问题均对世界教育提出了挑战。

④再次,信息时代为个人自由或自我实现提供了前所未有的机遇与挑战。
