二、阅读理解(共两节,满分30分)
第一节(共10小题:每小题2分,满分20分)
阅读下列短文,从每题所给的四个选项(A、B、C、D)中,选出最佳选项,并在答题卡上将该项涂黑。
A Londoners are great readers.They buy vast numbers of newspapers and magazines and of books---especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing.They still continue to buy “proper” books, too, printed on good paper and bound(装订)between hard covers.There are many streets in London containing shops which specialize in book-selling.Perhaps the best known of these is Charring Cross Road in the very heart of London.Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being “the biggest bookshop in the world” to the tiny, dusty little places which seem to have been left over from Dickens’ time.Some of these shops stock, or will obtain, any kind of book, but many of them specialize in second-hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written.One shop in this area specializes only in books about ballet!Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest.For the really cheap second-hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London.Here there is nothing so impressive as bookshops.The booksellers come along each morning and pour out their sacks of books onto small hand carts.And the collectors, some professionals and some amateurs, have been waiting for them.In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.21.“Londoners are great readers” means that _____.A.Londoners read a lot
B.There are a great number of readers in London C.Londoners are readers who read only great books D.Londoners are great because they read a lot 22.According to this passage, Charring Cross Road _____.A.is famous for its bookshops
B.is in the suburbs of London C.contains various kinds of shops
D.is the busiest street in London 23.In this passage, what does the underlined part “venture off the beaten track” mean? A.buy books in a most busy street
B.take a risk of losing one’s life C.waste time looking for books
D.move away from a busy street 24.On Farringdon Road, ____.A.you can find fine bookshops for the latest books
B.you can see book sellers selling books on hand-carts C.there are only small bookshops for the second-hand books D.the same books as the ones in the bookshops of Charring Cross Road are sold
B The scene in the Hollywood movie The Day After Tomorrow, where global warming could soon turn the global climate into a new ice age may never occur, according to new research.The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 740,000 years of climate data obtained from the Antarctic(南极)ice.Scientists from 10 nations have now almost completely drilled through a 3000-meter depth of ice high in the Antarctic mainland.They figure out that the area where summer temperatures can fall to-40℃,has at least 900, 000 years of snowfalls, kept as neatly as the growth rings of a tree.And the ice and air caught in each layer have begun to answer questions about the climates in the past.The results show that there have been eight ice ages in the past 740 000 years and eight warmer periods.And by comparing the pattern of global condition today with those of the past, the researchers reported in Nature that the present warm period could last another 15 000 years.Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures.It also shows that carbon dioxide levels are the highest for at least 440 000 years.“If people say to you: the greenhouse effect is a good thing because we would go into ice age otherwise, our data say no, a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey.“Now we have eight examples of how the climate goes in and out of ice ages...and you can learn what the rules are that go into the climate models that tell us about the future.”
Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level.“In 440 000 years we have never seen greenhouse gas get as thick as it is today,” said Dr Wolff.25.In drilling through the ice in Antarctica, scientists have found that____.A.the lowest temperature there is-40℃ B.the depth of ice is 3000 meters C.snowfalls are kept in certain patterns D.the ice has existed for 15,000 years 26.The information of the global climate conditions in the past can be obtained through ____.A.separating carbon dioxide from the air B.examining the growth rings of trees C.comparing temperatures in different areas D.studying the ice and air caught in each layer 27.We can infer from Eric Wolff's words that____.A.there is something wrong with the data B.greenhouse effect is always a bad thing C.greenhouse gas will get thick in the future D.a new ice age will not come in the near future
C Babies are born yogis.Once we were all able to pull our toes up by our ears and laugh about it.Then we aged, got injured, and began carrying stress in our shoulders and back.In short, we lost our balance.Yoga(瑜伽)is an ancient practice that helps create a sense of union in body, mind, and spirit.It brings us balance.I was seriously out of balance when I started practicing yoga in 1999.I had plantar fascitis(足底筋膜炎)in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis.I was desperate for exercise.Yoga became my salvation(拯救)and even enhanced my other fitness activities.I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.Yoga becomes part of your physical life.Your body grows stronger, more toned, and more flexible as you move from one pose to the other.I spent a week in Mexico at a yoga retreat(静修), and it was the first vacation on which I lost weight.“Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K.I.S.S.Guide to Yoga.“Because yoga helps maintain a balanced metabolism(新陈代谢), it also helps to regulate weight.Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day.After hours at my computer, I stretch my stiff shoulders and arms.When I need a boost of energy, I do energizing poses.When I am feeling exhausted at the end of the day, I do restorative poses.Yoga becomes part of your mental life.Yoga teaches you to focus on breathing while you hold the poses.This attention to breath is calming;it dissolves stress and worries.I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams.You should always leave a yoga practice feeling energized, not tired.If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses.In yoga, you “surrender” to the pose by letting go of the tension.Yoga becomes part of your spiritual life.Yoga is practiced by people from all religions;it is not restricted to any religious group.Yoga teaches “right” living in how we deal with ourselves and others.As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness.Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.28.What would be the best title for this passage? A.What’s Yoga?
C.How I Do Yoga Poses
29.People
feel
B.The Benefits of Yoga
D.The Varieties of Yoga
tired
after
yoga
because _____.A.they respond well to yoga poses B.they force themselves into yoga poses.C.they spend too much time on yoga
D.they consume energy in practicing yoga 30.If this passage continues, what will the writer most probably write about in the next paragraph?
A.Yoga as a means to keep fit.B.Different yoga poses.C.Popularity of yoga all over the world.D.Encouraging people to do yoga.第二节(共5小题:每小题2分, 满分10分)

七、Possible version: Dear Ms Zhong,88.withwithout 89.去掉of I am Johnson, a student from the 2015 A level Class in our school.Recently, I find that more and more students are taking food into the classrooms, packed in plastic bags, cups, and boxes.Therefore, our dustbins are all overfilled with plastic rubbish, which will float everywhere with the wind.This not only dirties our campus but also results in white pollution, causing damage to the environment.I think it’s high time we should take action.First of all, the school canteens should stop using plastics for food packing.Secondly, we should make rules that ban students from taking food into classrooms.Thirdly, we can hold an exhibition presenting the harmful effects of white pollution.With more students knowing the harm of plastics and fewer students eating and drinking in the classrooms, the use of plastics will be effectively controlled.Hope my suggestions will be useful.I am glad to do something for the improvement of our school environment.Yours sincerely, Johnson

A When Frida Kahlo’s paintings were on show in London, a poet described her paintings as “a ribbon(丝带)around a bomb”.Such comments seem to suggest Kahlo had a big influence on the art world of her time.Sadly, she is actually a much bigger name today than she was during her time.Born in 1907 in a village near Mexico City, Kahlo suffered from polio(小儿麻痹症)at the age of seven.Her spine(脊柱)become bent as she grew older.Then, in 1925, her back was broken in several places in a school-bus accident.Throughout the rest of her life, the artist had many operations, but nothing was able to cure the terrible pain in her back.However, the accident had an unexpected side effect.While lying in her bed recovering, Kahlo taught herself to paint.In 1929, she got married to Diego Rivera, another famous Mexican artist.Rivera’s strong influences on Kahlo’s style can be seen in her early works, but her later works from the 1940s, known today as her best works, show less influence from her husband.Unfortunately, her works did not attract much attention in the 1930s and 1940s, even in her home country.Her first one-woman show in Mexico was not held until 1953.For more than a decade after her death in 1954, Kahlo’s works remained largely unnoticed by the world, but in the 1970s her works began to gain international fame at last.21.The terrible pain Kahlo suffered was caused by _____.A.polio B.her bent spine C.back injuries D.the operations she had 22.Kahlo’s style had become increasingly independent since the _____.A.1930s B.1940s C.1950s D.1970s 23.What is author’s attitude toward Kahlo?
A.Devotion.B.Sympathy.C.Worry.D.Encouragement.B For much of my childhood, my mother filled in the evening hours doing something for someone else.Sometimes she knitted(编织)hats for babies, and at other times, she cooked chicken soup for sick neighbors.Therefore, I wasn’t surprised when one evening my mother announced she had undertaken a new project.“I am going to telephone seniors,” said my mother.“Every night? But you don’t even know these people.” “It doesn’t matter,” she said.“What’s important is that I listen.” I was sixteen years old and couldn’t understand why my mother was willing to spend her evenings talking to strangers.She had friends and my two older sisters to call if she felt lonely.“They will talk your ear off.Some people didn’t even stop to catch breath,” I said.My attitude didn’t decrease my mother’s enthusiasm for the project.That evening, she settled on the sofa and dialed.For a while, I listened as she asked the woman on the other line about her day and what she had eaten for dinner.When she finished the call, I said, “Why do you care whether she had cookies or rice pudding for dessert?” My mother grasped one of my hands and gave it a slight squeeze.“I’m the only person she talked to today.”
It took me more than thirty years to fully understand the significance of that statement.Now, as my mother is nearing eighty, I find myself thinking about those nightly calls she used to make.I am often the only person who telephones my mother, and sometimes I’m the only person she speaks to all day.I ask her what she cooked for dinner, but mostly I just listen as she describes a walk she took, or how her dog Lucky stole foods from the refrigerator.I realize that my mother’s calls were lifelines that ensured housebound seniors remained connected to the world.Without her, their world would have been empty.24.The writer wasn’t surprised about her mother’s decision because her mother _____.A.was a very creative person B.always devoted herself to helping others C.had nothing to do in the evening D.always got along well with the old 25.What’s the mother’s purpose of calling the seniors? A.To teach them how to make desserts.B.To kill some time in the boring night.C.To introduce some new friends to them.D.To make those old people feel less lonely.26.What does the underlined sentence “They will talk your ear off.” in Paragraph 2 mean? A.They will criticize the wrongdoings.B.They will be tired of listening to others.C.They will talk all the time on the phone.D.They will make you feel really satisfied.27.What can be inferred from the last paragraph? A.The author is going to be eighty years old.B.The author thinks highly of her mother’s calls.C.The author is the only person who speaks to her mother.D.The author’s dog likes stealing foods from the refrigerator.C Long ago, a man was reading the morning newspaper and noticed his name in the obituary(讣告)column.His first response was shock.After he calmed down, he sought to find out what people said about him.The obituary read, “Dynamite(炸药)King Dies” and “He is the merchant of death”.What should be given to the man was the inventor of dynamite, but being named “the merchant of death” was not how he wanted to be remembered.After a moment of reflection, he decided to change his life purpose.He made up his mind to work towards peace.His name was Alfred Nobel and he is widely known today by the great Nobel Prize.How do you want to be remembered? While we seldom deeply think of our own mortality(死亡), reflecting on the value of our life allows us to consider what is the most important.Life can be lived at an incredible pace but we sometimes fail to recognize its significance.It is vital to make the best use of our talents, ability or gifts to serve mankind.In his book Mastery, Robert Greene states, “In the end, money and success that truly last don’t come to those who focus on such things as goals, but to those who focus on mastery and fulfilling their life tasks.” Life mirrors your commitment to contribution.What we receive in life is proportional(成比例的)to what we should give.For this reason, be careful about how and where you spend your time and energy.Life honors those who make a big difference.If we wish to be remembered after we’re gone, we must live for something deeper while still alive and play big in the game of life regardless of fame or fortune.Alfred Nobel knew that being an expert on explosive was not how he intended to live out his days, so he created a new fate.28.After reading the news about his death, Alfred Nobel ______.A.continued his research to invent dynamite B.seemed satisfied with the comments on him C.was determined to struggle for new life goals D.planned to find out who had made the mistake 29.According to the author, the most important in life lies in _____.A.reflecting on our own faults B.doing good things for people C.understanding our value in life D.fulfilling our unique potentials 30.What can be inferred from Paragraph 3? A.Success comes from effort and determination.B.Inner desires and potentials give people power.C.Reward is given to those who make contributions.D.Wealth and success are the same goals for all people.31.What would be the best title for this passage? A.How to Change Fate B.Where to Get Honors C.Risks and Opportunities D.Living for Significant Purpose
D We all dream to reach a certain success someday.Because of this we all are afraid of the very same thing--failure.But we should understand that we all have to experience some sort of failure in our lives.It is part of growing up and it is part of life itself.Failure does not have to always be seen as something negative.When you get to see failure in a different view, you will see that it has the power to help you get to your goal.Do not be so hard on yourself whenever you make a mistake or fail at a task.Everyone makes mistakes.Whenever you face one failure, remember to accept your fault and do something to make things right.Whenever you fail at something, you just have to get up and keep trying.You will get to your goal eventually.Every mistake is a lesson you have to learn from.As the saying goes, “If you do something wrong for the first time, it is a mistake.But if it happens again, then it becomes a choice.” Your mistakes and failure make you wiser.You should be smart enough to know and avoid the causes that lead you to them once more.No dream or goal is ever easy.With every great success, there are some failures along the way that lead to something great.Do not give up and do not be afraid to make mistakes.It is all part of the game of life.Life is not a bed of roses.The journey to success will have its ups and downs and have its share of joy and suffering.You will encounter failure once in a while.But pain is part of the learning process.Failures and mistakes are experiences that will make you wiser and stronger as you climb the ladder of success.32.What is the main purpose of the passage? A.To encourage people to think of failure positively.B.To emphasize the importance of self-confidence.C.To explain some meanings of achieving success.D.To discuss the relation between failure and success.33.What can we know from Paragraph 2? A.Everyone should pay for their mistakes.B.Failure makes success more meaningful.C.Mistakes can bring people great benefits.D.It’s common to make mistakes in daily life.34.What does the author think of people who make the same mistakes again? A.They are complete losers.B.They are not good learners.C.They should not be forgiven.D.They need sympathy and support.35.The underlined word “encounter” in the last paragraph probably means_____.A.expect B.avoid C.experience D.appreciate 第二节(共5小题;每小题2分,满分10 分)

阅读下面的文字,完成11~14题。含泪奔跑的少年 朱钟洋
在他的记忆里,从未离开过生养他的大山,他今年初中毕业了,以优异的成绩考上了县城的重点中学。在城里,他这个年纪还是个孩子,还要在父母面前撒娇。然而,他俨然是个大人了,就在他初中毕业的这个暑假里,他尝到了冷也尝到了暖,冷暖过后,他仿佛一夜成人。
父亲在他初中毕业后第一个星期,突遭车祸,留下他和母亲相依为命。肇事司机也在车祸中死亡,父亲的死没有得到任何赔偿。母亲天生患有小儿麻痹症,走路一瘸一跛的,生活勉强能够自理。
起初,他和母亲商议着辍学,但母亲坚决不同意。为了下学期的学费,为了以后的生活有个着落,母亲决定带他到县城谋生。
进了城,他才知道,城市人山人海,高楼林立,但这些繁华不属于他们。沉闷的空气里弥漫着炙热的气流,一阵风习来,也闻不到稻花的香甜。母亲在城市边缘,租了间铁皮房,用木板搭了张床,然后找两块红砖架个小铁锅,算是在城里落下了脚。母亲从工厂找到店铺,从店铺找到垃圾收购站,可没有人愿意收留一个瘸子。无奈之下,母亲做了个烧烤车,还给他钉了个刷皮鞋的木箱。[来源:学科网ZXXK]
每天,他们从铁皮屋里出来,一个推着车,一个挎着刷鞋箱。趁着昏黄的路灯还没有熄灭,他们匆匆地赶到市里繁华的公园门口,占个地,摆个摊。等到公园里的最后一拨人散去后,他们才拖着疲惫不堪的身子回家。他心里其实有一万个不愿意,可是为了读书的梦想,他又能够说些什么呢。
大多数的日子,他就蹲在母亲的烧烤车边给人刷皮鞋。一天,他看到很多人在公园里,边看着孩子玩,边招呼人刷鞋,他心动了。他知会了母亲一声,便走进了公园深处。偏偏是这一天,城管突然来巡查,公园门口所有的小摊小贩一窝蜂地溜走了。走路一瘸一跛的母亲因为跑得慢了些,被城管逮了个正着。在和城管的纠缠中,烧烤摊被推倒了,烧得红彤彤的木炭倒在了母亲腿上,一股焦肉的味道让好心的路人愤怒了,城管见势不妙,很快怏怏离去。这天夜里,一对苦难的母子推着车,走着回家的路上,闪烁的街灯照在清冷的马路上,留下一对孤独的含泪的影子,一长一短地走着,成了一道痛苦抽搐的风景。
劳碌了一天的母亲,迷迷糊糊地睡着了,而他却怎么也睡不着。
他看着母亲翻了个身,腿上被烧焦的皮肤通红一片,有些地方还留下了水泡。他用手触碰了一下,感觉连心的痛。所有的委屈化成了泪水,从他的眼里流到了嘴里,涩涩的。
时钟已经指向了夜里11点多,他还是睡不着。为了赚够学费,他和母亲除了一日三餐外,其它的开支减了又减,实在要买点什么,也是选一些地摊货。而,刚刚,母亲连一盒烫伤膏也舍不得买,硬说擦点酱油就好了。这样一想,他的心更痛了,他失去了父亲,他不能再失去母亲了。他穿好衣服,走上街,向附近的药店跑去。
他跑进药店的时候,药店准备关门了。他很快选定了一盒26元的烫伤膏,他把烫伤膏攥紧在手里,就在掏钱的时候,他才发觉自己只是带来了今天全部的劳务费15元。他站在柜台前犹豫了很久。
“你到底要不要买啊,我们要关门了。”店主催促他。
“要的,要的,只是……只是,我没有这么多钱。”他吞吞吐吐。
“那就明天来吧。”
“哦不……我欠你11元钱可以吗?我明天下午一定还。”他快急哭了。
“那……”
“求求你吧……我妈妈她……”他心底的那点坚强终于崩溃了,泪雨滂沱,他把自己和母亲的遭遇说给了店主。
“那你,把药拿走吧,不够的钱,算是我资助给你的吧。”店主说,“快些回家吧,不要让妈妈等急了。”
母亲的腿上的伤很快就愈合了。他也如愿在县城读完高中,考上了省城的一所大学。
当他和母亲要离开县城,打算到省城继续谋生的时候,他整理好铁皮屋里所有的行李,突然一张药费单抖落了出来,他露出了笑容,他知道,上面写着——这个世界很冷也很暖,冷暖之间,我不能只是流泪,我要做一个含泪奔跑的人。

【解析】A.常温下,测定0.1mol•L−1 CH3COOH的pH值,若pH大于1,即可证明为弱电解质,选项A不选;B.常温下,乙酸钠溶液显示碱性,说明乙酸钠为为强碱弱酸盐,从而证明了乙酸为弱电解质,选项B不选;C.等体积的0.1mol•L−1 HCl和0.1mol•L−1醋酸溶液,中和这两种酸所需等物质的量浓度的NaOH溶液的体积相等,不能证明醋酸是弱电解质,选项C选;D.等体积的0.1mol•L−1 HCl和0.1mol•L−1醋酸溶液,分别与等量的颗粒大小相同的Zn反应,盐酸反应产生气泡的速率较快,说明醋酸不完全电离,是弱电解质,选项D不选。答案选C。 3.【答案】C 【解析】A.平衡时,不同物质的正逆反应速率之比等于化学计量系数之比,则达平衡时,3V正(NH3)=2V逆(H2O),A错误;B.若单位时间内生成x mol NO的同时,消耗x mol NH3,都表示反应向正向进行,不能说明反应到达平衡,B错误;C.达到化学平衡时,若增加容器体积,各物质浓度均减小,则正逆反应速率均减小,C正确;D.达到平衡时,若减小容器体积,相当于加压,平衡左移,则NH3的转化率会减小,D错误;综上所述,本题选C。 4.【答案】D 【解析】A.水是极弱的电解质,它能微弱电离生成等量的氢离子和氢氧根离子,故纯水呈中性,故A错误;B.向水中加入稀氨水,一水合氨电离出氢氧根离子,则溶液中氢氧根离子浓度增大,故B错误;C.纯水中c(OH−)×c(H+)=10−14=Kw,Kw是一常数,只与温度有关,温度不变,Kw不变,故稀酸和稀碱中Kw=c(OH−)×c(H+)=10−14,故C错误;D.水的电离是吸热过程,温度升高,平衡向电离方向移动,氢离子和氢氧根离子浓度增大,故Kw随之增大,故D正确;故选D。5.【答案】C 【解析】A.本来稀释10倍碱性变弱10倍,pH应该是10。但是氨水属于弱碱,弱碱部分电离,NH3•H2O NH+4+OH−加水稀释平衡正向移动,碱性稍大些,所以比10大些,但大不过11,故A 能用平衡移动原理解释;B.铝离子在水溶液中发生水解,AlCl3+3H2O Al(OH)3+3HCl↑,加热条件下氯化氢逐渐挥发,平衡正向移动,氢氧化铝受热易分解,2Al(OH)3===Al2O3+3H2O,所以把氯化铝溶液蒸干,灼烧,最后得到的主要固体产物是氧化铝,故B能用平衡移动原理解释;C.对2HI(g)H2(g)+I2(g)反应前后气体的物质的量没有变化,改变压强不会使平衡发生移动,而减小容器体积,气体颜色变深,是因为体积变小,碘蒸汽的密度增大,导致颜色加深,故C不能用平衡移动原理解释;D.因为溶解度S(CaCO3)<S(CaSO4),故水垢中的CaSO4时,加入饱和Na2CO3溶液,能将CaSO4转化为CaCO3,后加盐酸,水垢溶解,从而除去水垢,故D能用平衡移动原理解释;综上所述,本题正确答案为C。6.【答案】D

OH−+H2S,H2S有臭鸡蛋气味,与盐类水解有关,D不选。答案选C。8.【答案】B 【解析】A.导电能力越强,离子浓度越大,氢离子浓度越大,pH越小,则a、b、c三点溶液的pH为b<a<c,A错误;B.用湿润的pH试纸测量酸性的pH,a处溶液稀释,导电能力增大,溶液酸性增强,pH减小,所以测量结果偏小,B正确;C.随水的增多,醋酸的电离程度增大,所以a、b、c三点醋酸的电离程度:a<b<c,C错误;D.a、b、c三点溶液浓度不同,但溶质的物质的量相同,所以a、b、c三点溶液用1mol•L−1氢氧化钠溶液中和,消耗氢氧化钠溶液体积:a=b=c,D错误;答案选B。9.【答案】A 【解析】若反应向正反应进行到达平衡,X2、Y2的浓度最小,XY的浓度最大,假定完全反应,则: X2(g)+Y2(g)2XY(g)开始(mol•L−1)0.1 0.3 0.2 变化(mol•L−1)0.1 0.1 0.2平衡(mol•L−1)0 0.2 0.4 若反应逆正反应进行到达平衡,X2、Y2的浓度最大,XY的浓度最小,假定完全反应,则:

【解析】A.Na2CO3溶液水解显碱性,遇酚酞变红,加BaCl2溶液,水解平衡逆向移动,则证明Na2CO3溶液中存在水解平衡,选项A正确;B.瓶内有黑色颗粒产生,说明生成C,发生反应是4Na+CO2=====点燃2Na2O+C,CO2中C的化合价降低,因此CO2作氧化剂,被还原,选项B正确;C.在等浓度NaCl和Na2CrO4混合溶液中加入2滴AgNO3溶液,只生成白色沉淀,说明先生成氯化银沉淀,则Ksp(AgCl) 温度,化学平衡向正反应方向移动,反应达到新平衡前v(逆)<v(正),B正确;C.该温度下此反应的平衡常数K=,C错误;D.该反应前后气体的分子数不变,所以改变压强后,平衡不移动。其他条件不变,再充入0.2mol Z,相当于对原平衡加压,所以平衡时X的体积分数不变,D错误。答案选B。14.【答案】D 【解析】A.由图像可知加入氢氧化钠或氨水时,a的pH在开始阶段变化较大,应为碱滴定弱酸的变化曲线,则b、c为硫酸盐酸的滴定曲线,由于浓度未知,则不能确定b、c,故错误;B.硫酸、盐酸都为强酸,题中纵坐标为pH,不能确定浓度的大小,故错误;C.如用氨水中和,滴定终点时溶液呈现酸性,应用甲基橙为指示剂,故错误;D.开始时醋酸的pH为3,氢离子浓度为0.001mol•L−1,滴定终点时消耗氢氧化钠的体积为15mL,则有c×0.025=0.10×0.015,解c=0.06mol•L−1,故正确。故选D。15.【答案】A 【解析】A. 由图甲可知,升高温度醋酸钠溶液的pH增大,故其水解程度增大,A正确;B.Kw只与温度有关,a点Kw的数值与b点Kw的数值相等,B不正确;C.由图丙可知,T2对应的化学反应速率较大,故T2温度较高,C的平衡时的体积分数较小,故反应A(g)+B(g)===2C(g)是放热反应,C不正确;D.由图丁可知,反应C(金刚石,s)=C(石墨,s)是放热反应,由盖斯定律可知,ΔH=ΔH2-ΔH1,D不正确。本题选A。16.【答案】C 【解析】A.碳酸锰和硫化锰的组成形式相似,溶度积MnCO3>MnS,则碳酸锰的溶解度大于硫化锰的溶解度,故A正确;B. 碳酸锰中存在碳酸锰的溶解平衡,当加入硫离子时生成硫化锰沉淀,使碳酸锰的溶解平衡右移,反应离子方程式为MnCO3(s)+S2−(aq)MnS(s)+CO2−3(aq),故B正确;C.碳酸锰转化成硫化锰的反应方程式为:MnCO3+S2− MnS+CO32−,该反应的平衡常数为K= =

3、S2−的溶液中滴加氯化锰溶液,由于Ksp(MnS)<Ksp(MnCO3),则MnS比MnCO3更难溶,先产生沉淀是MnS,故D正确;故选C。17.【答案】(1)①0.3mol•(L•min)−1;②B(2)①−90.3kJ•mol−1;K1•K2•K3;②A(3)能 【解析】(1)①v(CO)=△c/△t=(2.0−0.5)mol•L−1/5min=0.3mol•(L•min)−1;②A.达到平衡时,H2的转化率为(2.0−0.5)mol•L−1×1L×2/4mol=75%,A错误;B.5min后反应达到平衡状态,容器中混合气体的平均相对分子质量不再改变,B正确;C.达到平衡后,再充入氩气,浓度不变,反应速率不变,C错误;D.在反应达到平衡前,v(正)>v(逆),D错误。答案选B。(2)①由盖斯定律可知,将已知三个方程式相加即得到反应Ⅳ,C(s)+2H2O(g)+CaO(s)CaCO3(s)+2H2(g)的△H=−90.3kJ•mol−1

Ⅱ.(2)1076 (3)①增大 反应ⅰ为吸热反应,升高温度,平衡正向移动,CO的平衡体积分数增大;反应ⅱ为放热反应,升高温度,平衡逆向移动,CO的平衡体积分数也增大 ②20% 0.044 【解析】(1)天然气的主要成分是CH4,根据题意,CH4与SO2反应生成H2S、CO2和H2O,反应条件是高温、催化剂。根据得失电子守恒和原子守恒配平化学方程式。(2)反应热=反应物总键能-生成物总键能,对于反应ⅰ,ΔH=(1319+442-678-x)kJ•mol−1=+7kJ•mol−1,解得x=1 076(或利用反应ⅱ进行计算,ΔH=(x+930-1 606-442)kJ•mol-1=-42kJ•mol−1,解得x=1076)。(3)①由题图知,随着温度升高,CO的平衡体积分数增大。反应ⅰ为吸热反应,升高温度,平衡正向移动,CO的平衡体积分数增大;反应ⅱ为放热反应,升高温度,平衡逆向移动,CO的平衡体积分数增大,综合来讲,其他条件不变,升高温度,体系中CO的平衡体积分数增大。②T1℃时,测得平衡时体系中COS的物质的量为0.80mol,则反应的n(COS)=0.20mol,故COS的平衡转化率为0.20 mol1 mol×100%=20%。反应ⅰ生成0.20mol CO,剩余0.80mol H2,生成的CO与H2O(g)发生反应ⅱ,设达到平衡时,参加反应ⅱ的CO为x mol,利用三段式法进行计算: CO(g)+ H2O(g)CO2(g)+H2(g)起始(mol)0.20 0 0.80 转化(mol)x x x x平衡(mol)0.20-x 1-x x 0.80+x 开始共投入3mol气体,且反应ⅰ和反应ⅱ都是气体分子数不变的反应,故平衡时体系中气体的总物质的量不变。根据题图知,T1℃达到平衡时,CO的体积分数为5%,故(0.20-x)mol3 mol×100%=5%,解得x=0.05。故平衡时体系中n(COS)=0.80mol,n(H2)=0.80mol+0.05mol=0.85mol,n(H2S)=0.20 mol,n(CO)=0.20mol-0.05mol=0.15mol,反应ⅰ的平衡常数K=c(H2S)•c(CO)c(COS)•c(H2)=0.20×0.150.80×0.85≈0.044。19.【答案】(1)不饱和 (2)= (3)b>a>c(4)BC(5)Ag2SO4+CrO2-4===Ag2CrO4+SO2-4 【解析】(1)曲线上的点都是处于平衡状态,此时纵、横坐标的乘积等于Ksp,a点对应的纵、横坐标的乘积小于Ksp,没有达到饱和。(2)Ksp仅与温度有关。(3)SO2-4对Ag2SO4的溶解起抑制作 用,使溶解度减小,SO2-4浓度越大,溶解度越小。(4)由Ag2SO4(s)2Ag+(aq)+SO2-4(aq)知A错;取图象中b点计算:Ksp=c2(Ag+)•c(SO2-4)=(2×10−2 mol•L−1)2×4×10−2mol•L−1=1.6×10−5(mol•L−1)3,B对;Q=c2(Ag+)•c(SO2-4)=(1×10−2mol•L−1)2×0.1 mol•L−1=1×10-5(mol•L-1) (3)1.0×10−12;1.0×10−10mol•L−1;=(4)①B>A>D>C;②D>C>A>B 【解析】(1)将等体积等物质的量浓度的醋酸和氢氧化钠溶液混合后恰好反应生成醋酸钠,醋酸根水解,溶液呈碱性,根据电荷守恒可知溶液中c(Na+)>c(CH3COO-)。(2)常温下,取0.2mol•L−1 HCl溶液与0.2mol•L−1 MOH溶液等体积混合恰好反应生成MCl,测得混合后溶液的pH=5,说明溶液显酸性,因此M+水解,则MOH是弱碱,电离方程式为MOH M++OH−。(3)99℃时,pH=6的蒸馏水中氢离子与氢氧根浓度均是10-6mol•L−1,则此时水的离子积Kw=1.0×10−12。加入NaHSO4晶体,保持温度不变,测得溶液的pH=2,即氢离子浓度是0.01mol•L−1,所以氢氧根浓度是10−10mol•L−1,硫酸氢钠抑制水的电离,则水电离出的氢离子浓度等于溶液中氢氧根的浓度,为1.0×10−10mol•L-1,硫酸氢钠不水解,则根据硫酸氢钠的化学式可知而此时溶液中的c(Na+)=c(SO2−4)。(4)①A.NH4C1溶液中铵根水解,溶液显酸性;B.NH4HCO3溶液中铵根与碳酸氢根的水解相互促进;C.NH4HSO4是强酸的酸式盐,电离出的氢离子抑制铵根水解;D.(NH4)2SO4溶液中铵根水解,溶液显酸性,铵根浓度大,酸性强于氯化铵;所以pH值由大到小的顺序是B>A>D>C。②根据以上分析可知NH+4离子浓度由大到小的顺序是D>C>A>B。21.【答案】(1)A;检查仪器是否漏水(2)溶液由黄色变为橙色,且在半分钟内不变色(3)D(4)26.10(5)= =26.10mL,c(NaOH)=0.1000mol•L−1×26.10ml25.00ml=0.1044mol•L−1 【解析】(1)A是碱式滴定管,使用滴定管前必须进行检查滴定管是否漏水;(2)选择甲基橙作指示剂,用标准的盐酸滴定待测的NaOH溶液时,当出现溶液由黄色变为橙色,且在半分钟内不变
