“Your mother's breast cancer has returned,and it's metastasized（扩散），“said my mother's doctor.I held the phone,tears in my eyes.
Even as a health-care professional,I had never really been able to do anything for my mother.She'd always been the caretaker,especially when I was in my teens,battling my own incurable illness.She'd arranged and accompanied me on trips to the Cleveland Clinic.During those long train rides,she'd always reach into her bag and
5
produce a gift——a Seventeen magazine—to lift my spirits.
Shortly after her diagnosis,I stopped by Mother's house.She'd wanted to live at home to look after herself while she could,so my sister and I took turns to check in on her.
As her health worsened,Mother eventually decided to stay with me in my house on the weekends and let me care for her.After I helped her into the house,she would stretch out on the sofa,my dog Spanky sleeping at her feet.I'd make us cups of Red Zinger tea.She'd look at me and say,"My purse,honey.”Inside would be one of her surprises, like a bag of treats for Spanky or a new pen for me.
At the end of her life,Mother was no longer conscious.Her wish was to be in my house.The night before,I moved all the furniture to prepare for the delivery of her medical equipment.The next morning,two guys lifted the sofa to move it，making room for the hospital bed.“What do we do with these,ma'am?"one asked.I looked over. He held up two beautifully-wrapped（包裹）gifts.How had they gotten there?I'd moved that sofa the night before and seen nothing!My hands shook as I unwrapped a toy for Spanky and a box of Red Zinger tea.
At that moment,it was as if my mother spoke directly to my heart,"Our little traditions will get you through this, Roberta,even if I can't take part anymore.

Did you know roughly one third of food for human consumption goes to waste?Most of it is fresh fruit and vegetables that go bad.The produce dries out or goes bad,which has led scientists to develop ways of coating or sealing the food to keep it fresher for longer.Now research at Rice University reveals there might be a better way.
Scientists discovered that dipping produce like strawberries and bananas into an egg-based wash is remarkably good for preserving it.The coating is extremely thick,and made from a mixture of powdered egg whites and yolks （蛋黄）（70%）,and some wood-sourced cellulose（纤维素）to act as a barrier preventing water loss.
What the scientists found was that the egg wash made a significant difference in helping produce stay fresh over a two-week observation period.The appearance of the coated fruits and vegetables didn't change much,while the uncoated produce ripened and even rotted within the same time frame.The egg-based coating,as it turned out, reduced each fruit's chance to get exposed to oxygen.
The non-poisonous coating was found to be flexible and tests showed that it was just as tough as other products, including synthetic films（合成膜）,used in produce packaging.For anyone with an egg allergy,the coating can be removed by thorough washing in water and is tasteless.
The scientists hope this could be a breakthrough in the fight against food waste."Reducing food shortages in ways that are not related to genetic modification,uneatable coatings or chemical additives is important for better
7
sustainable living said materials scientist and study author Pulickel Ajayan.
What's great about this discovery is that it fights food waste in more than one way：even the coating was made from eggs that would otherwise have been discarded because they weren't fit for consumption.The researchers said roughly200million of US-produced eggs go to waste annually.So if this were scaled up,it could be a win-win situation all around.
28.How does the egg-based wash help keep food fresh?
A.By limiting its oxygen exposure.
B.By making its coating less thick.
C.By removing its cellulose slowly.
D.By improving its absorbent ability.
29.Why is Pulickel Ajayan mentioned in the text?
A.To stress the seriousness of food shortage.
B.To offer the method of cutting food waste,
C.To show the significance of the discovery.
D.To give a brief description of the research.
30.What does the underlined word“discarded”in the last paragraph probably mean?
A.Eaten up.
B.Taken in
C.Picked out.
D.Thrown away.
31.What is the text mainly about?
A.How to use eggs creatively.
B.A new way to preserve food.
C.How to recycle food waste.
D.A breakthrough in technology.

Many studies have shown how playing video games can lead to structural changes in the brain,including increasing the size of some regions,or to functional changes,such as activating the areas responsible for attention. New research from the University at Oberta de Catalunya（UOC)has gone further to show how cognitive（认知的）changes can take place even years after people stop playing.
8
The study involved27people between the ages of18and40with and without any kind of experience with video gaming.
“People who were video gamers before adolescence,despite no longer playing,performed better with the working memory tasks,which require mentally holding and processing information to get a result,"said Marc Palaus,the author of the study.
The results show that people without experience of playing video games as a child did not benefit from improvements in processing and avoiding irrelevant stimuli（刺激）.Indeed,they were slower than those who had played games as children,which matched what had been seen in earlier studies.
"People who played regularly as children performed better from the outset in processing3D objects,although these differences were narrowed after the period of training in video gaming,when both groups showed similar levels/*said Palaus.
The study lasted a month and the researchers analyzed participants'cognitive skills,including working memory, at three points：before starting the training in video gaming,at the end of the training,and fifteen days later.The video game used was Nintendo's Super Mario64.
According to Palaus,what most video games have in common is that they involve elements that make people want to continue playing,and that they gradually get harder and present a constant challenge."These two things are enough to make it an attractive and motivating activity,which,in turn,requires constant and intense use of our brain's resources.”
"Video games are a perfect recipe for strengthening our cognitive skills,almost without our noticing.However, it's not the reason for playing too much,”he said.
32.What can be learned about the study?
9
A.It looks at different games.
B.It is aimed at adult gamers.
C.Its participants are adults.
D.Its author likes playing games.
33.How did people playing no video games as children behave in the study?
A.They tended to ignore irrelevant stimuli.
B.They failed to physically hold3D objects.
C.They performed very slowly after training.
D.They did worse in working memory tasks.
34.What may Marc Palaus suggest doing?
A.Finding recipes for better cognitive skills.
B.Avoiding getting addicted to video games.
C.Trying less challenging video games.
D.Forbidding video games for the young.
35.What is the best title for the text?
A.Playing Video Games as Kids Can Cause Changes in Brain
B.Video Gamers Memorize Information Much More Quickly
C.Video Games Help to Improve Children's Working Memory
D.Playing Video Games Benefits Cognitive Skills Even Years Later

Did you know that it's possible to save wet books by putting them in the freezer or refrigerator?Strange as it sounds,this simple trick can go a long way toward preserving beloved reading material that may be damaged from something as significant as flood water or as silly as knocking over a glass of water.36
Make sure that the water isn't dirty.37If a book has been soaked（浸泡）in dirty water or a colored liquid,it may be difficult to save the book.Realize,too,that the pages will never again be perfectly flat,only clear enough to read, if all goes well.
10
Determine the best approach to air-drying.If the book is completely soaked before freezing,don't try to separate pages.38If possible,put a sheet of paper towel between the covers and text body.If the book is partially soaked, spread paper towel throughout the pages of the book（every20or so）.After an hour of drying,change the towel until most water has been absorbed.
39Don't try to separate wet pages,as they may stick and tear.Put the book in the refrigerator as soon as possible. At the same time,keep the refrigerator on its"frost-free"setting,which helps to avoid the formation of large ice crystals（冰晶）in items,which can cause damage.40Once it gets frozen,it allows you
to open the book and spread the pages without them sticking together.
A.Here is how to do it.
B.Freeze the book immediately.
C.Put the book in the refrigerator after it dries.
D.The water has to be clean,for the most part.
E.There are many ways to clean and dry a wet book.
F.Leave the book in the refrigerator for at least24hours.
G.Make the book stand upright on paper towel that can absorb water.

山西省（康杰中学，忻州一中，长治二中，晋城一中，临汾一中）2018届高三第 山西省（康杰中学，忻州一中，长治二中，晋城一中，临汾一中）2018届高三第二次名校联考语文 山西省（康杰中学，忻州一中，长治二中，晋城一中，临汾一中）2018届高三第二次名校联考语文 一、现代文阅读（35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1-3题。 传统中国基本是将财权集中于中央为主，但由于管理区域的扩大和公共事务的增多，地方政府在承担一定政治、经济、社会功能与责任的同时，自然而然被赋予一定的财政权力，甚至在晚清还出现了中央财权下移和地方分权的现象。 清代初期，并没有严格意义上的中央财政与地方财政的分野，但有以起运存留为标志的中央财政与地方财政的划分和调整。起运与存留实质上就是中央与地方对于所征收钱粮按一定比例进行再分配。 清朝入主中原之后，事权的高度集中导致财权的高度集中。户部作为中央财政主管机构，制定财税征管政策，包括修订和编纂《赋役全书》以实现各省、州、县的赋役定额化；推行和利用诸如易知由单实征红簿串票截票等征税工具，以及滚单催征、顺庄编里等征收方法，确保赋役的足额征收。与此同时，通过起运、存留制度调剂中央与地方之间的收支比例，通过解款和协款制度调剂不同省份、不同地方之间的收支余缺，从而控制地方财政。 康熙朝以后还采取悉数解司与户部掌管奏销的举措，进一步强化中央对于地方财税的掌控。各地征收钱粮悉数解司等于取消了以州县为单位的财赋存留，州县正项经费开支必须随时向布政司及其所辖的户部寄存库领支。而清朝前期的奏销制度，除了由布政使司汇总所属府州县当年的赋税出入数额，核造上报计簿（奏销册）给户部审核外，还由督抚另外复核题奏，以达到相互监督之目的。雍正朝以后推行的耗羡归公，将地方官加征的杂税部分公开化和合法化，从而加强了预算外收入的管理，以实现其集权之目的。 从起运与存留的比例来看，清代中央有逐渐加强集权之趋势。清初，存留与起运各占一半，随着军费开支和中央财政的匮乏，中央政府开始对地方存留进行削减，地方存留所占比例逐渐减少。康熙中叶至嘉庆、道光年间，地方存留一般不超过25%，嘉庆末年甚至仅为17.4%。中央与地方财政分配比例从对半分配变成了头重脚轻的局面，形成集权型的中央与地方财政关系。 清代中央集权型财政关系至咸丰初年发生了变。此时，为了镇压各地起义，清政府军费开支急剧膨胀，中央财政左支右绌。为了维持王朝统治，只得允许各省自行经营筹划，从而导致地方督抚财权扩张。太平天国起义爆发，以湘军为代表的地方军事力量开始崛起，并且通过征收厘金和推行捐输等不同途径筹措军饷，而这些财政权力逐渐被地方督抚所掌控。厘金原本是为镇压太平天国运动而开征的一种临时税种，属于在商品的产、运、销等三个环节同时征收的商税。后来在全国推广并成为政府重要的财政收入来源，与田赋、盐课、关税等一起构成晚清的四大支柱收入。由于地方权重，厘金逐渐成为地方财政收入，而中央政府无法左右。正如郭嵩焘在《郭侍郎集》中所言：今之厘金，惟不限以科则，不拘以程式……一听督抚之自为。此外，捐输事宜虽要经户部批准，但各地方设立名目繁多的劝捐机构，户部根本无法考核其收支情况。各省督抚以厘金、捐输等自筹经费，必然导致地方督抚财赋支配权日重，而户部之权日轻，户部的奏销制度名存实亡。
