When it was her turn to pay, the cashier greeted her by name and asked her how she was doing. The woman looked down, shook her head and said, “Not so good. My husband just lost his job and my son is up t o his old tricks again. The truth is, I don’t know how I’m going to get through the holidays.” Then she gave the cashier food stamps.My heart ached. I wanted to help but didn’t know how. Should I offer to pay for her groceries or ask for her husband’s resume? I did nothing—yet. And the woman left the store. As I walked into the parking lot, I spotted the woman returning her shopping cart, and I remembered something in my purse that could help her in a different but hopefully profound（意义深远的）way. It wasn’t a handful of cash or a lead on a job for her husband, but maybe—just maybe—it would make her life better.“Excuse me,” I said, my voice trembling a bit. “I couldn’t help overhearing what you said to the cashier. It sounds like you’re going through a really hard time right now. I’m so sorry. I’d like to give you something.” And I handed her a business-sized card.A few weeks earlier, a colleague gave me a similar card as encouragement for a project I was working on. When I read the card, I felt a warm glow spread inside of me. Deeply touched, I came home and ordered my own box of cards and started sharing them too.When the woman read the card’s only two words, she began to cry. And through her tears, she said, “You have no idea how much this means to me.”I was a little shocked by her reply. Having never done anything like this before, I hadn’t anticipated the reaction I might receive. All I could think to respond was, “Would it be OK to give you a hug?” After the hug, I walked back to my c ar and began to cry too. The words on the card: You Matter.24. What’s one of the woman’s problems?A. Her son often plays tricks on others.B. Her family can’t spend their holidays.C. Her family’s total income will decrease.D. She can’t affor d the groceries.25. How did the author help the woman?A. By giving her some money.B. By returning her shopping cart.C. By helping her husband find a job.D. By inspiring her with confidence.26. What made the author want to have her own cards?A. The cashier’s greeting.B. The woman’s trouble.C. The card she received.D. Her colleague’s advice.27. Which is closest in meaning to the underlined word “anticipated” in the last paragraph?A. Prevented.B. Expected.C. Accepted.D. Noticed.CDieting to slim down always sounds great in theory. But with so many different types of diets, it’s tough to know where to start. Certain set of rules about food and exercise can last for two days, two months, or the rest of your life. Some recommend limiting your calories, while others suggest reducing your carbs（碳水化合物）. We don’t blame you if it all starts to make your head spin.To help narrow the options down, some health experts at U.S. News and World Report evaluated 40 of the most popular diets, and then ranked them according to factors like nutrition, effectiveness, safety, and ease. Overall, Weight Watchers was named the best diet for weight loss.The final results might not be what you think of. But if you think about it, it’s easy to see why Weight Watchers is such a star for weight loss. “Not only does it provide a healthy, effective program to shed pounds, but it also provides support for dieters through group me etings. That will keep you motivated in the long run,” the experts said.Meanwhile, the popular keto diet tied for last place, along with the Dukan diet. Whole30, another low-carb diet, was also at the bottom of the list. Why did these mainstream meal plans get a thumbs down from the experts? “The keto diet is just not sustainable over the long term,” nutritionist Lisa Drayer said. “It doesn’t teach you how to acquire healthy eating habits. It’s good for a quick fix, but most people I know can hardly gi ve up pasta and bread, let alone beans and fruit.”“Still, that doesn’t mean you should nix（否决）your New Year’s resolution altogether,” Drayer said. “Just make sure your diet fits with your lifestyle and goals—no matter which one you choose. Before you get started, read up on the surprising things doctors wish you knew about losing weight.”28. What can we learn from the first paragraph?A. It’s hard to choose a proper diet.B. Some diets can result in a headache.C. Dieting to slim down is easy in practice.D. Different diets can be used altogether.29. What’s the reason for Weight Watchers’ standing out?A. It supports dieters both physically and mentally.B. The method it provides is cheaper and easier.C. It searched for and learned from most popular diets.D. It focuses much attention on its users’ safety.30. What problem do people usually meet in losing weight?A. Some diets are harmful to health.B. Many diets are hard to carry out.C. Body weight sometimes declines sharply.D. It’s difficult to make a decision to lose weight.31. What does Drayer advise dieters to do?A. Make higher goals.B. Keep suitable diets.C. Abandon present diets.D. Learn from other dieters.DIn a test, scientists at the Pacific Northwest National Laboratory（PNNL）in southeastern Washington mixed low-activity radioactive waste—that is, waste with very small concentrations of radioactivity—with liquid glass, then let it harden into a durable（持久的）, solid material. This process immobilized（使固化）the radioactive and chemical materials within the glass, the PNNL said.“The radioactive elements are chemically bound as part of the glass material,” Will Eaton, who led the test, told Live Science. “A nd the glass material is a durable waste form that separates the radioactivity from the environment for a very long time.”For the experiment, carried out in April, scientists took about 3 gallons （11 liters）of low-activity waste from a tank at the Hanford Site, a nuclear production complex located next to the PNNL in southeastern Washington. This small-scale test is a key step forward in the goal of dealing with millions of gallons of dangerous waste that was made from more than 40 years of plutonium（钚）production at Hanford, whose reactors produced plutonium for America’s defense program, the PNNL said.To trap the dangerous liquid waste in glass, scientists mixed it with glass-forming materials, such as silica, and then slowly pumped the mixture into a melter that reached 2,100 degrees Fahrenheit（1,148 degrees Celsius）. At the end of the test, the scientists had about 20 pounds（9 kilograms）of glass.If the glass breaks, as it did in the test, then you have many pieces of glass. The waste components are chemically bound and are a part of the glass material. The dissolution（分解）of the glass over time（which happens very slowly）depends on surface area, so cracking has a very small effect on leaking into the environment.Later this year, researchers plan a second vitrification test on about 2 gallons（7.5 liters）of waste from a different tank at Hanford. However, this waste will test different filtration- and ion-exchange methods, the PNNL said.Once this test is completed, the low-activity waste glass containers will be stored in the Integrated Disposal Facility at the Hanford Site.32. What’s the significance of the test?A. It makes reactors produce less radioactive waste.B. It provides an alternative material for the defense program.C. It helps increase the production of plutonium from reactors.D. It contributes to a new method of treating radioactive waste.33. What can we know about the test?A. The mixture was melted at a high temperature.B. Liquid waste was poured into a glass container.C. Solid waste powder was mixed with liquid glass.D. A whole piece of clear glass was gained at the end.34. What does the fifth paragraph mainly talk about?A. Instructions for breaking up the glass.B. Possible result of the dissolution of the glass.C. Technical requirements for keeping the glass.D. Ways to prevent waste entering the environment.35. What would be the best title for the text?A. Special Kind of Glass Being TestedB. Radioactive Waste Trapped Inside GlassC. Durable Material Made of Glass and WasteD. New Way Found to Recycle Radioactive Waste第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。
河南省洛阳市孟津县第二高级中学备战2022高考高二语文9月月考试题不分版本河南省洛阳市孟津县第二高级中学2020-2022学年高二语文9月月考试题一、现代文阅读〔36分〕〔一〕论述类文本阅读〔此题共3小题，9分〕阅读下面的文字，完成1～3题。
“民生〞，这几年已经成了社会生活中分外响亮的“主题词〞。
政府出台“民生政策〞之密集，媒体推出“民生话题〞之深入，百姓关注“民生热点〞之强烈，可谓前所未有。
如何使每一级政府的惠民之举，托起每一个百姓的幸福生活? 显然，我们还有许多的结待解。
走进基层，常常遇到一些令人忧虑的现象。
民生是个“筐〞。
看一看各地在抵抗金融危机中接连推出的刺激内需的大手笔，看一看基层在跟进产业转移中争相展示的招商引资的新路数，其中究竟有多少是真正关乎民众切身利益的惠民工程，有多少是紧密照应民众迫切需求的民生工程! 一些地方向上汇报、对外宣传时，为了标榜自己的“高度重视〞，竟然把高速公路、城市广场等根底设施投资都算作了民生工程。
民生是个“秀〞。
“有粉搽在脸上〞，这是许多官员的共通心态。
就谈新农村建设，不少地方忙于撤并村庄、洗脚上楼，简单地将城市样式照搬进来，靠近路边的建筑，还要涂脂抹粉，配上白墙红顶。
老百姓的谋生之道、生产方式还没有改变，就急着要在一个早上颠覆农民既有的居住文明和生活方式，于此，官员们有了迎接上级领导检查视察的“盆景〞，有了自己表功炫耀的“面子〞，甚至还有了其中房地产开发的“实惠〞，老百姓却尝到了难言的苦果。
民生是个“痛〞。
一些地方政府或盲目追求跨越开展，或急于拉动投资需求，或企图摆脱财政困境，提出加速城市化，让更多的百姓以承包土地换一纸户籍，尽快过上城市生活，享受公共效劳，沐浴现代文明。
但是，他们并没有换位思考：农民到城里买不起房怎么办? 找不到工作怎么办? 子女就学遇到困难怎么办?民生是什么? 不是口号，不是标榜，它是百姓的切身利益，是人民的幸福生活。
民生建设是什么? 不是政绩工程，不是权宜之计，它是一种执政理念，一种开展方式，一种社会文明。
