For people in many European countries, healthy food,regular exercise and taking time to relax are part of their daily routines.Here are the top three healthiest countries in Bloomingberg's list this year.SpainAs the world's healthiest nation in the 2019 Healthiest Country Index,people in Spain have a“Mediterranean diet”.It includes seafood, nuts and vegetables.However, the healthiest thing about Spain is not the food,but rather the relaxed way that people enjoy it.While eating out,they may stay to talk,keep getting together,and perhaps share a glass of wine. If the conversation gets good, they'll stay for hours until late night.ItalyLike Spain，Italy＇s typical（典型的）eating diet also plays a huge role in the country’s health. Besides eating, Italians typically walk or cycle to their schools and ually,they spend less time sitting around than people in other countries.IcelandIceland is one of the healthiest countries in the world.For example, they live very long lives. When it comes to eating,Icelanders keep things simple: lots of fresh dishes made up of seafood and dairy（奶制品）from grass-fed cows.This diet reduces the risks of some serious diseases.Maybe the most important is that hot springs （温泉）provide Icelanders with a relaxing place. Besides, they travel too much.31.Spanish people stay outside for hours until late night because theyA.talk happilyB.eat a lotC.have a glass of wineD.travel too much32.Which of the following is NOT the reason for Icelanders' long lives?A.Hot springs.B.They eat healthily.C.They keep getting togetherD.They travel too much.33.What do people in Spain, Italy and Iceland do in common?A.Travel around.B.Drink wines with their friends.C.Spend time sitting around.D.Eat healthy food and take time to relax.BLater in the summer， Tom decided to go digging for buried（埋藏）treasure.He found Huck and told him all about the places that robbers hid their treasure and a treasure map.One day,they decided they would start digging under a dead tree near the haunted house.They talked about what they would do with their treasure. Huck said he would spend his so his father couldn't get any of it. They dug for a while, and then gave up and tried another place.There's no treasure there, either. Tom realized they should return at midnight to dig again. As a result, the boys failed to find treasure that night.Finally they both agreed that the next day they would dig in the haunted house,and Huck believed they were taking chances to get treasure if they did.They met again with their tools and went to the haunted house. They explored the downstairs, as they got ready to leave,they heard two men coming to the door of the house.Scared,the boys hid themselves upstairs to see who they were. They recognized one man. It was Injun Joe! The unknown man was saying something dangerous. Tom and Huck were scared to death, so they stayed quiet. The men were talking about some “work” that the unknown man believed to be too dangerous. Tom and Huck couldn't believe they were watching real robbers bury treasure! It included thousands of dollars in gold and treasure.The men wanted to bury all their treasure again when Injun Joe started wondering why there were some tools in the house. Surely someone was there, he decided to hide the money somewhere else. He then started looking around the house for the owners of the tools. He was almost up the stairs when the bad wood broke and he fell down.Then the boys walked home quickly.---Taken from The Adventures of Tom Sawyer34.The underlined word “it” in Paragraph 2 may meanA.the treasureB.a treasure mapC.a dead treeD.the haunted house35.Which is TRUE according to the passage?A.The robbers dug under a dead tree.B.The robbers found the owners of the tools.C.The two boys got the treasure successfully.D.The two boys escaped from the haunted house.36.From Paragraph 3,we can know thatA.the boys saw two men leaving the door of the houseB.the boys hid themselves upstairs to get the treasureC.the two robbers planned to do something dangerousD.the two robbers stayed quiet because they were scared37.Which of the following words best describes the two boys' feeling in the last paragraph?A.Afraid.B.Sad.C.Curious.D.Bored.CWhat is a hero? We may think of the fictional characters with super powers or great people who caninfluence world events. Now,as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia（新冠肺炎），medical workers have become heroes in the eyes of the public.As of Feb 19,a total of 32,000 medical workers outside Hubei province have been working to treat patients around the center of the outbreak.Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes,since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep.Even suffering from amyotrophic lateral sclerosis（肌萎缩侧索硬化），the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients.“I have to run,racing against time to save more patients from the deadly disease, because I don't have much time left in my life,” Zhang told Xinhua News Agency.With the duty of saving lives,many medical professionals like Zhang have been working long hours for days,despite their fear and worries.Lu Jingjing from Wuhan Children's Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.“It's dangerous but we should win the battle with the virus as soon as possible, so that medical workers and patients can go back home,” she told China Daily.Everyone has fear, especially when it comes to deadly diseases. But for medical workers,saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life，but in these extraordinary（不同寻常的）times，they are heroes.38.What do we learn from Zhang Dingyu's words?A.He hopes to live for a longer time.B.He would like to have enough sleep.C.He wants to help as many patients as possible.D.He feels sorry for himself because of his illness.39.Why doesn't Lu Jingjing answer her parents' video calls?A. She is too busy and has no time for video chats.B.She doesn't want her parents to worry about her.C. It's not allowed to make a video call from the hospital.D.There is no network signal at the temporary mobile hospital.40.The best title of the passage can beA.A terrible diseaseB.A patient doctorC.A beautiful girlD.A true hero41.You may find this passage in aA.newspaperB.dictionaryC.guidebookD.novelDAccording to a survey，U.S. customers care about their personal information and identities（身份） duringthe holiday season. But the survey shows these worries won't affect how they shop. On the days of deals（交易日）-online and in stores-create even more opportunities to steal customers＇ information. Here are some simple tips to protect your personal data.Be aware of your surroundings. 43 percent of identity theft comes from a stolen wallet,checkbook, credit card,or other physical document. While holiday shopping, keep an eye on your things and stay aware of what's going on around you.Be careful with those public, unsafe coffee shop Wi-Fi networks. If you use an unsafe network, other users on the network can see what you see and what you send. They could break into your conversation and log in as you.New hacking tools available for free online make this easy, even for users with limited technical know-how.Think carefully about providing your information. Mobile shopping apps are convenient, but they can store your name, address, phone number, email details. Look for apps that are clear about how they keep your data safe. Never provide information tied to your identity, like your bank account number, to someone announcing to be from a government business.And， as all customer protection guides will tell you，don＇t send cash（现金）. Is someone asking you to send money immediately for a deal that seems too good to be true, or saying you qualify for a government support but need to send them a cash fee to receive it? Don't buy it. Scammers will ask you to pay in ways that let them get cash fast-and make it rather difficult for you to get your money back.42.What did the survey show in Paragraph 1?A.U.S.customers are afraid of shopping.B.U.S.customers' information is stolen every day.C.U.S.customers care about their personal information.D.U.S.customers usually shop online instead of in stores.43.Where does identity theft sometimes come from?A.Your nameB.Your credit cardC.Your emailD.Your phone number44.The underlined word “Scammers” in the last paragraph may mean_A.受害者B.目击者C.抢劫犯D.诈骗犯45. In order to protect our personal data, we'd bettere coffee shop Wi-Fi networks if possibleB.take notice of your surroundings while shoppingC.provide your information while mobile shoppingD.send cash to the government business if you are asked to四、词汇运用（共10小题；每小题1分，计10分）（每空一词）46.Read carefully before you do DIY.（指示）47.The Spring Festival is one of our festivals.（传统的）48.I've never the decision to work in West China.（后悔）49.The weather report says there will be haze on.（星期四）50.Spring is coming and the temperature will rise zero.（在···上面）51.Could you tell me how to make the tomato soup much.(tasty)52.Dick decided to lose by eating less and doing more exercise.(weigh)53.How you will find it to use the mobile phone if you read the function!(easy)54.The three students Miss White paid attention to great progress at last.(make)55.I think there is little chance that robots will take the place of in the future.(human)五、阅读表达（共5小题，每小题2分，计10分）Have you touched a cute dog recently? If that dog touches you with its nose, you may find how wet and cold it is. If dogs are so warm and fluffy（毛茸茸的），then why are their noses so cold？Before, people thought that dogs had cold noses to help them control their body temperature. But, a new study has shown some interesting findings about dogs' noses. The study finds that when the air temperature is 30°℃,the tip of a dog's nose is about five degrees cooler than the air. But why is this?The researchers believe that the tip of a dog＇s nose has a special sensory function（探测功能）.So， they do an experiment to test it. The study shows that dogs can find weak heat sources-like a small animal-with their noses from 1.5 meters away.The research team studies three dogs named Charlie, Delfi and Kevin.For the experiment,the dogs have to tell the difference between two objects.The two objects are heated to different temperatures. Amazingly,all three dogs are able to sense the temperature difference between both objects.The study also finds that the heat from the objects in the experiment is too weak to be felt by human hands,even at very short distances. The dogs are able to sense these heated objects from a distance, but humans are only able to feel the warmth of the object if they touch it.To know more about it,the research team also studies the brain activity of 13 dogs. When a warm object is put near their noses, there is an increase in brain activity.根据短文内容回答问题（每小题答案不超过10个单词）。

再说运动员的拼博精神对我难道不是一种鼓舞吗？你说对吧！（四）探究（8分）12．阅读下面的几段资料，从中你有什么发现？写出你探究的结果。

（1）乌鸦，嘴大而直，全身羽毛黑色，国家二级保护动物。

多群居在树木中或田野间，喜欢选择高达二十米以上的乔木做巢、栖息，如果树木低于二十米，乌鸦就会离去，另选高枝。

主要以谷物、果实、昆虫等为食物。

喜欢闪闪发亮的东西，常常收集碎玻璃渣子等。

（《现代汉语词典》）（2）随着改革开放，随着沈阳城急剧向四周扩展，尤其从上世纪90年代初开始，乌鸦们不知受了什么诱惑，夜幕下三三两两，犹如一道道黑色闪电，悄悄潜入沈阳城区，或落在古老教堂钟楼顶，或飞到老乔木上栖息，而清晨来临天还未亮，又很自觉地飞离。

那时进城乌鸦数量少，又都很羞怯，人们的正常生活未受到干扰。

（《江海晚报》）（3）1999年秋天，沈阳获得联合国的人居奖，城市靓丽起来，乌鸦们似乎也要来分享这份荣耀了。

如一传十，十传百，百传千一般，数以万计的乌鸦们四面八方向沈阳城聚集，不再是三三两两，而是成群结队；不再是悄悄潜入，而是鸦噪齐鸣漫天飞舞；不再是暮来晨去，而是早归晚出；不再是仅仅栖息于闹市公园，而是地盘扩大到五公里，占领了最繁华地段的天空。
