Artificial intelligence,or AI,has been applied in a wide range of fields to perform specific tasks,including education, finance, heavy industry, transportation, and so on.

Education

There are a number of companies that create robots to teach subjects to children ranging from biology to computer science,though such tools have not become widespread yet.Advancements in natural language processing,combined with machine learning,have also enabled automatic grading of assignments.AI has also led to an explosion in popularity of MOOCs,or Massive Open Online Courses,which allows students from around the world to take classes online.

Finance

Use of AI in banking can be tracked back to 1987.Banks use artificial intelligence systems to organize operations,maintain book-keeping,invest in stocks,and manage properties.Also,systems are being developed,like Atria,to translate complex data into simple and personable language.There are also wallets,like Wallet AI,which monitor an individual’s spending habits and provides ways to improve them.

When 1 was a boy we used to live across the road from a big hill with huge oak trees growing out of it.When winter arrived,thick,heavy snow would fall,and my two brothers would grab their sleds heading over to the hill for a day of fun.I remember watching them with envy because 1 was still too small to go sledding.Finally,one winter 1 was considered big enough and joined my brothers as they carried their sleds up the long hill and prepared to ride down it.

The first few trips I rode with one of my brothers and had the time of my life.It was so exhilarating when the wind whipped across my face as I flew down the hillside on the wooden sled.Near the end of the day 1 was overjoyed too when my oldest brother decided to let me try riding the sled all by myself.I climbed on it full of excitement and lay on my stomach.Then with one big push my brother sent me down the snowy hillside.1 was doing pretty well too until I hit an old stump hidden by the snow and went off course,straight towards one of those big oak trees.My heart pounded in my chest and I could hear myself screaming.At the last possible second I rolled off and the sled crashed into the tree.I could hear my brothers running down the hill yelling,“You have to steer(操控)!You have to steer!”

Sadly,that wasn’t the last time I failed to steer when some obstacle knocked me off course in my life.Many times problems,troubles,and my own failures have sent me crashing into the trees of anger, frustration, and despair.I am still learning that life isn’t always safe sledding.I am still learning that it is up to me to steer myself back to love, back to kindness, back to goodness, and back to God.

Life is a trip,but no one ever said it was a smooth ride.Steer well then.Steer straight.Steer your soul towards the light and the love we are all meant for.

The popular TV program Readers has prompted more people in China to practice reading aloud in booths(亭)set up in big cities across the country.

As the latest TV show to help people’s love for literature recover,CCTV program Readers invites people from all walks of life to read aloud their favorite poems,essays and books,or even personal letters they wrote to their loved ones.Just as the weekly show has been well-received,its reading booths,equipped with professional recording devices and cameras,have become instant hits.

A crowd of more than 200 people were pictured lining up outside the Shanghai Library at 11 am on March 4 --the first day of the booth’s opening to the public in Shanghai.The deadline for registrations was brought forward to 2 pm instead of the scheduled 5:30 pm,as the number of waiting readers continued to grow.Some waited more than nine hours for a try-out in the booth, according to library management.

“There is an old photo in the late 1970s capturing people lining up outside the Shanghai Library before it opens.If that was a spring of reading in Shanghai,now I think another spring has arrived again,”library manager Zhou Deming,told the Shanghai-based The Paper.

The reading booth is the only one of its kind in the city of economic center at the moment,but more are expected to be put into use in the coming months,according to the library’s website.

The Readers program has also led to booths in other cities including Beijing,Hangzhou,Guangzhou and Xi’an to appeal to more people to read and share their life stories.

With the recent boom of culture-themed TV shows such as Readers and Chinese Poetry Competition,some are optimistic that this will help the country love literature and reading again in general.

Following the crowd may not always be in a person’s best interest.But new research suggests that teens who go along with their friends may end up healthier as adults.

Scientists have known that close friendships help boost health.That’s true for both teens and adults.The finding inspired Joseph Allen,a psychologist at the University of Virginia,and his team to study whether experiences during teen years would influence adult health.

So they followed 171 teens,starting when the kids were just 13.They interviewed each one every year for

five years,and also spoke to these teens’closest friends,who provided additional information about the quality of their friendships.The same 171 people were interviewed again at ages 25,26 and 27.This time,the questions surveyed each person’s overall health.When the researchers analyzed the data they found a strong connection between a teen’s behavior and adult health.Teens who had close friends grew up to be the healthier adults.Whether teens held back their feelings or expressed them to a close friends also influenced later health.Those who held back were more likely to be sick as adults.The connection held up even after the scientists accounted for other possible influences on health.Weight,family income and drug use were all examined.So were mental health issues,such as anxiety and depression.And in these people,such other factors did not explain adult health as well as teen friendships did.

Going along with the crowd may have benefits,says Allen,but there are also drawbacks.Teens who are more independent tend to do better at school and work.And peer pressure may lead some kids to engage in risky behavior,such as smoking,drinking or using drugs.Dealing with it is an ongoing challenge,Allen acknowledges.“Finding the right balance is the key.Teens shouldn’t lose heart for not finding this easy.”And,he adds,“Parents need to be understanding about the pressures teens face.”

32.Where can you probably read this passage?

A.Science fiction

B.Health column

C.Fashion magazine

D.Entertainment newspaper

33.We can learn from Allen’s study that _______________.

A.many other factors have a greater influence on adult health than teen friendships

B.mental health issues have nothing to do with adult health

C.the same 171 teens were interviewed each year from 13 to 27

D.the teens who couldn’t express themselves grew up to be unhealthier

34.According to what Allen said,we can know that _______________.

A.in order to do better at school,teens should not follow the crowd

B.though it’s challenging for teens to deal with peer pressure,they should not give up

C.teens will engage in smoking,drinking or using drugs when facing peer pressure

D.parents should understand their teens and stop them going with friends

35.What can be inferred from the passage?

A.There is nothing bad for teens to follow the crowd.

B.Close friendships are the most important for people’s health.

C.Teen friendships may turn out healthier adults.

D.Adult health is only influenced by teen friendships.

广东省惠州市2018届高三文综(历史部分)第三次调研考试试题(含解析)

2018届高三惠州市第三次调研考文综历史试题 1. 秦统一后,在全国实行郡县制,每郡设监郡御史一名,是中央最高监察机构御史府在每 郡设置的派出机构,其职责主要在于监察一郡地方官吏。此后,这种派出管理制度一直延续至清代。这一制度 A. 削弱了地方权力 B. 形成了地方割据势力 C. 加强了中央集权 D. 维护了大一统的局面 【答案】C 【解析】中国古代的派出制度从秦一直延续至清,材料已经明确派出制度的基本内涵,不难推断出。根据材料对派出制度的阐述可知并没有削弱地方权力,故A错误。B与材料逻辑明显不符。从秦至清,其中不乏分裂时期,但仍实行派出制度,此项制度不足以达到维护大一统局面的作用,故D不选。作为中央派出机构监督地方官吏,显然是为了加强中央集权,故选C。 2. 王阳明提出“致良知”与“知行合一”的工夫论,强调道德实践不再是迫于外在天理的 合目的性行为,而成为真正意志自由的主体行为。王阳明的主张 A. 彻底否定程朱理学 B. 启迪了明清之际进步思潮 C. 维护封建道德伦理 D. 逐渐成为官方的统治思想 【答案】B .................. 3. 历史叙述一般包括史料呈现、史实陈述和历史解释等。下表是不同时期的学者对李贽形象的历史叙述

这反映出 A. 历史叙述应当尊重历史事实 B. 历史解释目的在于揭示历史事实 C. 时代立场不同影响历史解释 D. 历史叙述的差异性揭示历史本质 【答案】C 【解析】本题考查学生的基本史学素养。本题从不同时代的学者对晚明李贽的不同评价来考查学生的史学素养.。历史解释是历史叙述的一部分,基于同一历史事实,历史解释由于学者所处时代、所持立场以及学识等各方面的原因呈现多元化,故答案为C.。 4. 清初小说《姑妄言》曾写到:“你道这好儿子不送去念书,反倒送去学戏,是何缘故?但他这昆山地方,十户之中有四五家学戏。以此为永业,恬不为耻。”这一现象说明当时 A. 儒学主流地位受到冲击 B. 经济发展推动观念转变 C. 小说成为文学主要形式 D. 民众需求促进戏曲兴盛 【答案】B 【解析】从材料“以此为永业,恬不为耻”明显看出这是一种价值观的转变,结合材料提示的时间空间——清代昆山,可知这是商品经济发展的产物,故选B。A明显与史实不符。明清古典小说繁荣,成为文学的主流形式,但与材料不符,故不选C。戏曲兴盛确跟民众需求相关,但也与材料含义脱离,故D错误。

It includes airfare ($225), hotel ($170), dining out ($116) and dressing up ($95) and the gift. If you have weddings to attend this year, here are some tips for you to avoid breaking the bank. 1. Book flights in advance The moment you decide to attend a wedding is the time to check flight prices at the best time. Plane fares are higher in the summer, especially in July and August. Booking in advance will save you money, as will watch for sales on lower-cost carriers like JetBlue and Frontier. You can check Google Flights for a calendar of prices showing the cheapest days to fly from apps like Hopper to get real-time alerts when a fare is at its lowest price point. 2. Don't blow your budget on the gift If you've got the money, an expensive gift is lovely. But there's no need to take out loans to prove your love for the happy couple. Skip an expensive necklace by giving (an appropriate amount of) cash instead. To save on the gift, consider making one: A photo album or scrapbook of memories with the bride and groom shows how much you care. You could also share the gift with other guest(s) or even make gifts with DIY ideas by yourself to save money. 3. Use old dresses and suits You don't always have to be on a new dress for a wedding. While men have the option of repeating their suits, women are more likely to spend money on new clothes for the special occasion. But before you take out your wallet, consider reinventing something already in your
