Her mum Leigh-Anne said the drama began during a visit to her grandma’s house when her grandparents gave her older kids some sweets.“Then at about 4:45 pm, Tallulah started to choke—we all went into a panic.”“It seemed like it went on for ages. Not one of us knew what to do.”“I rang an ambulance while my grandma and granddad tried to get the sweet to come up.”“Tallulah was panicking at first but then she started to go purple—she almost had no oxygen left in her.”With her daughter limp (无力的) and time running out, Leigh—Anne knew she couldn’t afford to wait for the ambulance to arrive.“The only thing I could think was to go out into the street.” She said.“I rushed out and screamed for someone to help while my grandma rushed out crying with Tallulah.”At exactly the moment, Caitlin, who is studying public services atRedcarCollege, was passing byQueen Street. She said, “I was waiting to go to work when I heard someone screaming for help, so I ran straight over.”The 17-year-old girl added, “Something just clicked and I went into auto mode. The little girl was completelylimp, so I checked her airways and tilted (使倾斜) her over and started hitting her back. I turned her round and tapped on her chest, then after what felt like forever she coughed up the sweet and spat it out.As soon as she started crying I felt a huge relief.

The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop inLatin America.Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is aboutconvertingforests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force forextinction, particularly of large species.”The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2than the natural systems can actually absorb, which is clearly not sustainable.”Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.8. According to the passage, what kind of species faces the biggest drop in population?A. Land and ocean species.B. Animals with backbones.C. Freshwater species inLatin America.D. Freshwater species in the tropics.9. All the following can contribute to the loss of world’s wildlife population EXCEPT ________.A. turning wildlife habitats into agriculture land.B. making sustainable use of wildlife.C. hunting illegally.D. emitting CO2 gases and pouring nitrogen.10. Which does the underlined word “converting” in paragraph 4 mean?A. Conserving.B. Conveying.C. Exchanging.D. Transforming.11. It can be inferred from the passage that _______.A. Marco is much concerned about human’s current behaviors towards wildlife.B. what the planet provides now can satisfy human’s sustainable development.C. more than half of the world’s wildlife population has been lost.D. if humans reduce the effects on the climate, the whole species will not disappear.DIt is that time of year when people need to lock their cars. It’ s not because there are a lot of criminalsrunning around stealing cars. Rather, it’ s because of the good-hearted neighbors who want to share their harvest. Especially with this year’s large crop, leaving a car unlocked in my neighborhood is an invitation for someone to stuff it full of zucchini(西葫芦).My sister-in-law, Sharon, recently had a good year for tomatoes. She and her family had eaten and canned so many that they began to feel their skin turn slightly red. That ’ s when she decided it was time to share herblessings.She started calling everyone she knew. When that failed, she began to ask everyone in the neighborhood like a politician, eventually finding a neighbor delighted to have the tomatoes. “ Feel free to take whatever you want,”Sharontold her. She felt happy that she could help someone and that the food didn’t go to waste.A few days later,Sharonanswered the door. There was the neighbor, holding some bread. The neighbor smiled pleasantly, “I want to thank you for all of the tomatoes, and I have to admit that I took a few other things and hope you wouldn’t mind.”Sharoncouldn’t think of anything else in her garden that had been worth harvesting and said so. “Oh, but you did,” the neighbor said. “You had some of the prettiest zucchini I’ve ever seen.”Sharonwas confused. Zucchini in her garden? They hadn’ t even planted any zucchini. But her neighbor insisted that there really were bright-green zucchini in her garden. The two of them walked together into the backyard. When the neighbor pointed at the long green vegetables,Sharonsmiled, “ Well, actually, those are cucumbers that we never harvested, because they got too big, soft and bitter for eating or canning.”The neighbor looked atSharon, shock written all over her face. Then she smiled, and held out the bread that she had shared all over the neighborhood, “I brought you a loaf of cucumber bread. I hope you like it.”12. Why does the author suggest that people in the neighborhood should lock their cars?A. They might be stolen by thieves.B. They might be moved away by the police.C. Their neighbors might fill them with their harvest.D. Their neighbors might throw rubbish in them.13. What does the underlined word “blessings” in the second paragraph mean?A. Tomatoes.B. God’s protection.C.Helpful things.D. Best wishes.14. What did the neighbor do inSharon’s garden?A. She harvested tomatoes only.B. She harvested zucchini by accident.C. She took some cucumbers mistakenly.D. She stole something withoutSharon’s permission.15. We can infer from the article that the neighbor’s bread would taste________.A. bitter but tastyB. strange and bitterC. hard and sourD. soft and sweet第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

江苏省淮安市高三上学期语文第一次调研试卷姓名:________ 班级:________ 成绩:________一、现代文阅读 (共2题；共30分)1. （16分）(2020·赣县模拟) 阅读下面的文字，完成下列小题。

材料一：我国保障了人们的饭碗安全，对维护国内稳定、全面建成小康社会打下了坚实的物质基础；同时中国用占世界9%左右的耕地解决了世界近20%人的吃饭问题，为世界粮食安全作出了重大贡献。

目前，全国75%以上的粮食产量、90%左右的调出量来自13个主产省份，并持续北移。

面对粮食生产格局变化，国家积极推进北粮南运，维护区域粮食安全。

我国粮食储备率远远高于国际公认的17%至18%安全线。

近年来一些国家发生的粮食危机警示我们，粮食依然是弱势产业。

粮食安全，根本在耕地，出路在科技。

由此。

我国实施藏粮于地、藏粮于技战略。

藏粮于地，就是要坚守耕地红线，确保耕地数量不减少，开展高标准农田建设。

习主席对新时期农业生产提出了更高要求，提出给农业插上科技的翅膀。

藏粮于技，就是走依靠科技提高单产的内涵式发展道路。

(摘编自张帆《全力以赴保障我国粮食安全》材料二：中国人口占世界的近1/5，粮食产量约占世界的1/4，中国依靠自身力量端牢自己的饭碗，实现了由“吃不饱”到“吃得饱”，并且“吃得好”的历史性转变。

在国家政策的强力支持下，粮食安全形势迎来历史最好水平。

如图示：材料三：进入新世纪，我国粮食安全的环境发生了很大变化，在粮食安全问题上，必须居安思危。

我国改革任务繁重，工业化、城镇化快速推进，粮食安全面临诸多挑战。

随着农村劳动力向非农产业和城镇转移，农业兼业化、农民老龄化、农村空心化日益严重，外出农民工特别是新生代农民工不愿回乡务农，农业生产面临后继乏人的现状。

我国人均资源较短缺，人均耕地面积仅为世界平均水平的40%，人均水资源拥有量不到世界平均水平的25%。

资源破坏、环境污染、水土流失等一系列生态问题，导致粮食生产的资源环境约束日益显现。

2020届江苏淮阴中学高三语文一模试卷及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成各题。

材料一：什么是大数据，迄今并没有公认的定义。

从宏观世界角度来讲，大数据是融合物理世界、信息空间和人类社会三元世界的纽带，因为物理世界通过互联网、物联网等技术有了在信息空间中的大数据反映，而人类社会则借助人机界面、脑机界面、移动互联等手段在信息空间中产生自己的大数据映像。

从信息产业角度来讲，大数据还是新一代信息技术产业的强劲推动力。

相较于传统的数据，大数据具有体量大、速度快、模态多、难辨识和价值大密度低的特征。

但大数据的主要难点并不在于数据量大，因为通过对计算机系统的扩展可以在一定程度上缓解数据量大带来的挑战。

其实，大数据真正的挑战来自于数据类型多样、要求及时响应和数据的不确定性。

（摘编自程学旗等《大数据系统和分析技术综述》）材料二：“神威·太湖之光”，系统采用全国产处理器构建，峰值性能每秒超过12.5亿亿次，是世界第一的超级计算机。

2017年，共有五项基于“神威·太湖之光”的应用入围国际高性能计算应用领域最高奖“戈登·贝尔奖”的提名，其中两项获奖，这是中国高性能计算应用领域近年来最重大的突破。

“神威·太湖之光”将如何改变我们的生活？“‘神威·太湖之光’有着大数据应用的天然优势。

”中国工程院院士陈左宁说。

超算具有强大的数据存储、检索、计算、分析能力，而现在的大数据应用与新一代人工智能密切结合，“神威·太湖之光”将为二者深度融合应用提供技术支撑。

“未来，国家超算无锡中心将是一所‘人工智能’大学。

”科学家张晖这样描绘未来。

他说，这所大学的学生并不是人类，而是人工智能机器人。

在超算的“培训”下，智能机器人将拥有独立思考的“头脑”。

比如医院的CT机可以代替医生去诊断分析病情，通过大量数据的计算，选择最优解决方案，甚至比人做得更好。

One common quality is that they are diligent and down to earth, which best demonstrates that Chinese people are a hardworking people. Of course, there are many other qualities we can learn from them. For example, happiness of the people always tops the list in their dictionary, and the interests of our country outweigh their own personal ones.What impresses me most is that Yuan Longping lives a simple but meaningful life. More often than not he wears a cheap shirt when going to work in the fields. By contrast, too many teenagers nowadays take it for granted to ask their parents to buy them famous brands without hesitation. Personally, we should follow heroes in their footsteps, applying ourselves to study, helping others selflessly. Only by setting noble ambitions can we become promising and make contributions to our country.录音原文：Text 1M: I never listen to the radio anyway. I can just check the weather on my phone.W: I do the same thing. I’m never home to watch the weather forecast on television, either.Text 2W: Are you going to make it to the basketball game tonight? I will be there right after debate team practice.M: I can’t. I have a big math test tomorrow. I have to prepare for it.Text 3W: It looks like you’re having a hard time with that program, Larry. Why don’t you use the method that I gave in the class yesterday?M: I was absent. I’ll ask one of my classmates to send it to me.Text 4W: If we want to win the game this Friday, we need to come up with a plan now. They beat us every year.M: We need to use teamwork more. John is our best player, but we can’t give him the ball every time.Text 5W: Excuse me? I’m trying to pay the parking, but all I have is dollar bills. Could you spare any change?M: I’m sorry, madam. But our store policy is not to give out change unless you buy something.W: OK.Text 6W: Tim, I saw you running from the bus stop this morning. You r mother and father wouldn’t be happy seeing you do that.M: I was late for school though.W: You need to be more careful when you cross the street. You need to walk during the right time and in the right places.M: But I’m very fast.W: Are you even listening to me? It is dangerous. It is also against the law.M: But I hate waiting for the lights to change and the cars to pass by. I don’t want to be late.W: It is important to obey the rules, but your safety is more important. I don’t want to see anyone o f my students get hurt.Text 7W: Sorry, Jim. I won’t be able to make it to the dinner tomorrow night. I’ll be busy volunteering at the library during that time.M: That’s interesting, Carol. Most people I know volunteer by collecting garbage or something. What do you do at the library when you volunteer? Are they short on employees who put away books?W: Nothing like that. I just read the children’s books and act out some of the stories for them. It’s very fun and it doesn’t take long, maybe one or two hou rs.M: How often do you do that?W: I do it on Monday, Wednesday and Friday every week. You should come help me with it one time.M: That sounds like fun. Can I pick the stories I want to read? I hate to try and act out a story I never read.W: You can re ad any book as long as it’s on the library’s list.Text 8M: I was reading about superfoods today. They are fruits, vegetables and other foods that are supposed to be extra healthy.W: That’s interesting. Which foods are they? I suppose rice is high on the list. We certainly eat a lot of that here in China.M: No, it isn’t. Nor are noodles. But yogurt, fish and tomatoes are there.W: Oh well, I suppose we eat plenty of them. Why are these foods so healthy?M: It’s said they can reduce the risk of high blood pressure, heart disease and certain cancers.W: Maybe I will start including them in our meals. Are there any foods on the list that we don’t have yet?M: Nuts and greens are something we already eat plenty of. And although our type of rice — the white kind —isn’t on the list, brown rice is.W: Then I think we will switch to that to keep the family healthy. Superfoods sound like a very tasty way to keep fit.Text 9M: I can’t believe this. I have been on the phone with my bank all day and they still haven’t fixed my problem. W: Is it a credit card problem?M: Yes. My credit card information was stolen. When I got my bill in the mail, I saw there were many unfamiliar purchases on it.W: That’s terrible. Did they take a lot of money?M: Yes, and I am very upset because the bank is not helping me quickly. I have talked to many different managers already.W: Doesn’t the bank’s owner need to make the decision to give you your money back?M: No. I just have to prove that these purchases were not made by me.W: I hope you can fix this problem soon. Something similar happened to my husband’s mother recently. She was tricked into giving away some important information over the phone.M: I think the person who stole my information got it from the Internet. I bought a collection of movies recently. I won’t be doing that again unless the website is sure to be safe. It’s honestly my fault for being careless.W: You can never be too careful. Well, your problem is inspiring me to look into protecting my account better. I think I can pay my bank more to help me.Text 10W: Listen up you two. We need to leave this house before the sun rises tomorrow. Your father will be home soon from work and once he gets home, we will be packing our bags. We need you guys to do the same thing tonight. I want everything you’re going to bring put out in the living room before you go to bed. Before you pack everything though, you need to put aside the clothes for tomorrow. I don’t want to wait for you to search for other clothes or to unpack your bag to get something. Our flight is at 7:00 a.m., and it will take about a half hour to get to the airport from here. We’ll probably need another hour to get through security. Also, I know I said that we would go out for our meal tonight, but there is just too much to do. I asked your father to pick up some Chinese food for dinner instead. I can’t be bothered to cook something since I just cleaned everything. If you want a specific dish at the restaurant, you will need to call your father. Otherwise, he will just pick up something that we can all share. Are you clear on everything I said?。
