Fortunately, Europe has more to offer than lots of old churches and ancient history. You can enjoy some fun with your kids in the sun at some of the famous ‎ beaches of the continent.‎ Mykonos, Greece The closer you get to the equator, the longer the beach season is, and Greece is wonderful for that. You can enjoy beautiful green water, public chairs and lovely umbrellas at the beaches in Mykonos.‎ Dubrovnik, Croatia There's nothing more attractive than the beautiful beaches bordering Dubrovnik, Croatia's most beautiful city. It's surrounded by stone walls like a castle. It almost makes you feel like you're suntanning (日光浴) at Hogwarts, where the hero Harry Potter of the story is trained!‎ Sicily, Italy Rabbit Beach on the island of Sicily offers shallow and crystal clear waters, making it a perfect beach for families with young children. And if you want to add interest to your experience, try snorkeling (徒手潜水)．‎ Nice, France Lined with palm trees and firstclass hotels, the city of Nice, located on the French Riviera, offers a whole coastline of Mediterranean beaches. Because they're in the heart of the city, these beaches attract a large crowd. So if you're looking for something more private, you'll have to travel a few miles outside of the city center.‎ Ribadeo, Spain At low tide, Playa de las Catedrales in Ribadeo, Spain is the perfect beach to take in the natural wonders without urban amusements like restaurants, bars or huge crowds. It boasts beautiful wild flowers and unique rock formations making it truly a picture worthy.‎ 1.What makes Dubrovnik so special?‎ A．It is surrounded by stone walls.‎ B．It has the most attractive coastline.‎ C．It has the longest beach season.‎ D．It is the training center of Harry Potter.‎ 解析：选A　细节理解题。根据第三段的“There's nothing more attractive ... It's surrounded by stone walls like a castle.”可知，克罗地亚的杜布罗夫尼克的特别之处就是它像城堡一样被石墙围绕。‎ ‎2．If you plan to go to a beach in the city, where should you go？　‎ A．Mykonos.　　　　　　 B．Sicily.‎ C．Nice. D．Ribadeo.‎ 解析：选C　细节理解题。根据倒数第二段的第二句“Because they're in the heart of the city, these beaches attract a large crowd.”可知，选C。‎ ‎3．Which of the following is TRUE about Ribadeo?‎ A．Visitors can try snorkeling there.‎ B．It offers visitors firstclass hotels.‎ C．It has restaurants, bars and huge crowds.‎ D．Visitors can enjoy unique rock formations there.‎ 解析：选D　细节理解题。根据最后一段的最后一句“It boasts beautiful wild flowers and unique rock formations making it truly a picture worthy.”可知，游客们可以欣赏到西班牙的里瓦德奥独一无二的岩石构造。‎ ‎4．What do all the beaches have in common?‎ A．They have beautiful wild flowers.‎ B．They are famous European beaches.‎ C．They are wellknown for their green water.‎ D．They provide visitors with urban amusements.‎ 解析：选B　细节理解题。根据文章第一段多处出现的Europe和“You can enjoy some fun ... the continent.”可知，文章中介绍的所有景点都在欧洲，结合全文可知，这些景点都是海滩。‎ B I have lived in America's countryside for nine years, first in Michigan, where I was getting my university degree; then in central Illinois; and now in Indiana, where I am a university teacher. There were a few things I enjoyed complaining (抱怨) about in my living area. I'm a vegetarian (素食者), so there's nowhere to go out for a nice dinner without taking a 50mile drive. I'm black, so there's nowhere to get my hair done without another 50mile drive.‎ I repeated these complaints to my parents and my friends. Sometimes it seemed like complaints were the common language in my circle. We all were dissatisfied with something. Back in Illinois, my friends complained about the train to Chicago and how it's never on time; my friends in bigger cities complained about the expensive rent and strange smells on the subway.‎ Complaining allows us to accept the imperfect without having to take action. We all have great ideas about what life would be like if only we had this, or did that, or lived there. Perhaps complaining helps bridge the large space between these perfect selves and reality.‎ There's also this: I really didn't want to change most of the things I complained about. Complaining was helpful on those days when happiness required too much energy. But it also made me lose sight of something. I was born and grew up in Nebraska and have lived most of my life in one of the plains states. When I went to the coasts, I was surprised by how unattractive bigcity living can be.‎ Complaining may offer relief, but so does acceptance. There is no ‎ perfect place. There is no perfect life. There will always be something to complain about. By focusing on (关注) my complaints, I risked missing out on important moments of happiness. Now, I look up into the night sky and see all the stars. And I know that I have nothing to complain about.‎ 语篇解读：本文是一篇议论文。作者曾是一个爱抱怨的人，然而她最终意识到抱怨不会带来任何改变还会使她错过许多美好的时刻。‎ ‎5．What do we know about the author?‎ A．She likes driving in the countryside.‎ B．She is very picky about her hair.‎ C．She is a well educated woman.‎ D．She often goes out for dinner.‎ 解析：选C　细节理解题。根据第一段中的“I was getting my university degree”和“I am a university teacher”可知，作者是一个受过良好教育的人。‎ ‎6．After complaining, the author probably________.‎ A．had a deeper understanding of reality B．tried to make herself more perfect C．got sadder about her situation D．remained unchanged 解析：选D　推理判断题。根据第三段中的“Complaining allows us to accept the imperfect without having to take action.”和第四段中的“I really didn't want to change most of the things I complained about”可推测，作者抱怨过后基本不作出任何改变。‎ ‎7．What does the underlined word “something” in Paragraph 4 refer to?‎ A．The fact that the author liked the countryside.‎ B．The difference between small and big cities.‎ C．The difficulty in finding happiness.‎ D．The purpose of the author's life.‎ 解析：选A　代词指代题。画线词something指的是后面的两句“I was born and grew up in Nebraska and have lived most of my life in one of the plains states. When I went to the coasts, I was surprised by how unattractive bigcity living can be.”由此可知，作者想表达她所忽略的事情是：她生养于有着大片平原的内布拉斯加，并且一点儿都不羡慕大城市的生活，即：她曾经非常喜爱乡村生活的事实。‎ ‎8．The author writes the text mainly to ________.‎ A．make her complaints B．tell us to stop complaining C．compare different lifestyles D．tell us life is the same anywhere 解析：选B　写作目的题。根据最后一段特别是最后一句“And I know that I have nothing to complain about.”可知，作者写作此文旨在告诉我们应该停止抱怨生活，并且希望我们可以更多地关注生活中的美好。‎ C If living in a big city makes you feel a bit down, there's good news: A brief walk in nature could be all it takes to drive away those negative thoughts. At least that's the finding of a new study published in the Proceedings of the National Academy of Sciences.‎ Several other studies have also suggested that there's just something about being in nature that can give our moods a boost (提升). But it hasn't been exactly clear what's going on in our brains when we're ‎ exposed to natural environments. One possibility is that nature decreases “rumination (反思)”， or patterns of negative thoughts that swirl in our heads and seem to take over.‎ To find out if nature helps us end that cycle of negative thoughts, Bratman and his colleagues randomly assigned 38 volunteers to take a 90minute walk in either a natural or an urban area. Before and after the walk, the participants filled out a questionnaire about how much they were ruminating, and had their brains scanned using a form of fMRI that measures blood flow in the brain at rest. The nature walkers reported having fewer negative thoughts about themselves after the walk than before the walk, while the urban walkers reported no change. What's more, fMRI brain scans revealed less activity in the subgenual prefrontal cortex (SGPFC) of those who walked in nature. SGPFC is a brain region (区域) that may play a key role in some mood disorders and has been linked with patterns of negative thought. Those who went for the urban walk did not show any of these benefits, the study found.‎ At last, we may have a possible explanation for how being in nature may improve our mental wellbeing. In addition, the findings suggest that having green spaces and natural areas in cities may be important for maintaining our mental health.‎ ‎9．What does the new study mainly show?‎ A．Taking a walk is really beneficial.‎ B．Negative thoughts aren't that hard to remove.‎ C．Living in cities results in negative thoughts.‎ D．Walking in nature contributes to a better mood.‎ 解析：选D　细节理解题。根据第一段的“A brief walk in nature ‎ could be all it takes to drive away those negative thoughts.”可知，这个研究主要表明在自然环境中散步可以改善心情。‎ ‎10．When the activities in SGPFC in our brains increase, ________.‎ A．we tend to enjoy a good mood B．we may develop more negative thoughts C．we may want to walk more D．we tend to get rid of mood disorders 解析：选B　推理判断题。根据在自然环境中散步可以改善心情以及第三段的“What's more, fMRI brain scans revealed less activity ...”可知大脑里这种物质增加可能会让我们有一些负面的想法。‎ ‎11．What is the passage mainly about?‎ A．Scientists have solved a difficult mystery.‎ B．Scientists have found how to maintain mental health.‎ C．Scientists find more trees are needed in cities.‎ D．Scientists find an easy way to boost our mood.‎ 解析：选D　主旨大意题。根据文章内容可知，主要是讲科学家发现了一种可以很容易改善我们的心情的方法。‎ D ‎(2018·东北三省四市教研联合体模拟)‎ On April 14th, 2010, my entire life changed in an instant. One moment I was joyfully riding through the sunshine. The next moment, metal, flesh and bones were spreading against the pavement in a thunderous crash. Another cyclist, biking carelessly, had cut me off and sent me supermanning toward oncoming traffic.‎ As if to symbolize the accident that had hit my life, another disaster also occurred on April 14th, 2010. It cost the airline industry $1.7 billion.‎ ‎ Ten million travelers were stuck for days. Economics all over the world were disturbed. This was the eruption of Eyjafjallajokull, one of Iceland's many volcanoes.‎ However, volcanoes are not all bad. In fact, they are necessary. They are responsible for the birth of new earth, and for the creation of rich soil. This eruption gave off 0.15 million tons of carbon dioxide into the atmosphere daily. But cancelling 48% of the world's flight travel saved about 2.8 million tons of CO2 from entering the atmosphere, temporarily decreasing our carbon footprint.‎ Similarly, the accident had badly affected my emotion but it also allowed me to look more closely inside myself and discover things about myself I would never have realized. I learned how not to judge myself for my new limitations.‎ In 1973, another Icelandic volcano, Eldfell, broke out. Icelanders decided to bomb it with cold water until it froze and chose a different path. After their plan worked, they used the geothermal (地热的) energy for the next 15 years to heat their homes. A good example of life bringing lemons, and making lemonade! One must move on from misfortunes, focusing only on the present moment and being hopeful for the future.‎ I ran from April 14th, 2010, to every kind of escape. Eventually I ended up in university for a newfound love in Earth sciences.‎ 语篇解读：作者把自己遭遇突发事件和火山爆发这种自然灾害进行类比，说明遭遇到不幸也有好处，面对现实情况要乐观积极。‎ ‎12．What happened to the writer on April 14th, 2010?‎ A．He was involved in a car crash.‎ B．He was stuck in an Iceland's airport.‎ C．He witnessed a volcanic eruption.‎ D．He was badly injured on a bike ride.‎ 解析：选D　细节理解题。根据第一段中的“The next moment, metal ... crash.”和“Another cyclist, biking carelessly ... oncoming traffic.”可知，一个马虎的骑自行车的人撞到了作者，作者遭遇了事故，受伤严重，故D项正确。‎ ‎13．Which was an effect of the eruption of Eyjafjallajokull?‎ A．The economy was cost globally by the eruption.‎ B．Carbon dioxide increased temporarily.‎ C．Most of the world's planes were held up.‎ D．The earth in Iceland was terribly polluted.‎ 解析：选A　细节理解题。根据第二段中的“Economics all over the world were disturbed.”可知，冰岛的埃亚菲亚德拉冰盖火山爆发后，全世界的经济都受到了干扰，即火山的爆发使全球经济受损，故A项正确。‎ ‎14．Why did the writer mention the Eldfell volcano?‎ A．It broke out in Iceland on April 14th as well.‎ B．It symbolized the accident that changed his life.‎ C．It told us to make the best of a given situation.‎ D．It encouraged him to know more about himself.‎ 解析：选C　推理判断题。根据第五段中的“After their plan worked ... their homes.”并结合下文中的“One must move on from misfortunes, focusing only on the present moment and being hopeful for the future.”可推知，我们应该充分利用特定的环境。‎ ‎15．What is the best title for the passage?‎ A．Escape from Volcanoes B．Inspiration from Disasters C．Love for Earth Sciences D．Attitude Toward Nature 解析：选B　标题归纳题。本文作者通过讲述自己遭遇事故和火山爆发带来的好处及坏处，告诉人们要积极应对现实情况，所以选B项。‎ Ⅱ.阅读七选五 Your weekends are precious and you'll surely want to make the most of them. Here are some tips to help you make the most of your weekends.‎ ‎__1__ Decide during the week exactly what you're aiming to do at the weekend. This doesn't mean you can't allow for a bit of flexibility here and there. But in the main you should know what you want to get out of your weekend.‎ Meet up with your friends. You nearly always have the best time with your friends, yet sometimes you may put off making that phone call to arrange something because you are a little lazy. __2__‎ Get outdoors. Simply get outdoors and go for a walk, run, hike, cycle or anything else you can think of! __3__ Admittedly, the weather should be on your side.‎ Set aside some time. Filling your time with all sorts of activities can be fun, but it can also be tiring. So, try to set some time aside for yourself. __4__‎ ‎__5__ There are some things that can be done at any time — not just at the weekend. If you arrange your time in the week well, then you will have plenty of time at the weekend to do the things you really want to do.‎ A．Make plans.‎ B．Find a new hobby.‎ C．Finish some things in the week.‎ D．So the day will pass without you having done anything.‎ E．Getting a bit of exercise and fresh air will leave you energized.‎ F．Then, you can enjoy yourself by reading a book, or listening to some music.‎ G．However, if you make the effort, you will have a wonderful time with your friend!‎ ‎1选A　根据空格后“Decide during the week exactly what ...”可知，本段的小标题是做计划。‎ ‎2．选G　根据前文“yet sometimes you may put off making that ...”可知，然而，如果你做出努力，你将和你的朋友度过美好的时光。G项中的effort指的是上一句提到的“making that phone call to arrange something”。‎ ‎3．选E　根据前文“Simply get outdoors and go for a walk, run, hike, cycle or ...”可知，运动和呼吸新鲜空气会让你精力充沛。‎ ‎4．选F　承接上文“So, try to set some time aside for yourself.”可知，然后你就可以开心地阅读或者听音乐。‎ ‎5．选C　根据后文“There are some things that can be done at any time — not just at the weekend.”可知，本段小标题是在周内完成一些事情。‎ Ⅰ.语法填空 Now many singers and bands have little to do with good music.They know little about __1__ good music means.What is the cause?‎ Most of these singers so far __2__ (see) music as a “job” because it ‎ is a good way of making money.And if you have a good __3__ (appear) and also original or expensive clothes to show off at your concerts then your voice is not as __4__ (importance) as it should be.The public will prefer to admire more the most interesting parts of your body and even forget that you are there __5__ (show) your music skills, not your dancing, which is important too, but not at such a high level.‎ Therefore, many young girls on TV choose to wear the most provocative (挑逗性的) clothes to catch attention, but when it comes to __6__ (sing) they are in __7__ complete mess and one doesn't need to have an ear __8__ music to notice their lack of talent.‎ However, the young generation should understand talent and a good voice matter more in their musical career.All the bands that have little to do with good music fail to __9__ (view) as successful on stage.If a young man has a great voice and wants to become a singer, he should take some special courses in this area, __10__ will help him improve singing abilities.‎ 语篇解读：如今很多乐队和歌手仅仅因为金钱而从事音乐事业，反而忘了音乐的真正含义。‎ ‎1．what　空格处所填词引导宾语从句，并在从句中作means的宾语，表示“什么”，因此用what。‎ ‎2．have seen　句中的“so far”表明用现在完成时。且“Most of these singers”与see之间为主动关系，故用have seen。‎ ‎3．appearance　空格前的“a good”表明这里应用名词appearance。‎ ‎4．important　此处是as ...as ...结构，两个as之间用形容词或副词的原级，由空格前的be动词is和句意可知，此处用形容词作表语。‎ ‎5．to show　此处应用动词不定式to show ...作目的状语。‎ ‎6．singing　when it comes to (doing) sth.表示“当谈及……时”‎ ‎，为固定搭配，其中to是介词，故此处用动名词singing。‎ ‎7．a 　in a mess表示“混乱，一团糟”。‎ ‎8．for　have an ear for表示“对……有鉴赏力”。‎ ‎9．be viewed　fail to do sth.表示“未能做某事”，为固定搭配；the bands与view之间是被动关系，再由view ...as ...(把……看作……)结构可知，故此处用被动形式be viewed。‎ ‎10．which　先行词是special courses，关系词在非限制性定语从句中作主语，故用which。‎ Ⅱ.短文改错 I am writing to tell you anything about the transportation in China.Over the past few decades we have developed an amazed network of public transportation.Besides, we have been decided to make efforts to make them much better.I am sure a network will satisfy your needs for traveling everywhere more convenient.People usually chose the means of transportation based with some aspects, such as the cost and the time needed.For example, businessmen are more likely travel by plane or highspeed train to save time while office worker tend to take buses or drive to work themselves.‎ 答案：第一句：anything→something 第二句：amazed→amazing 第三句：去掉been; them→it 第四句：a→the; convenient→conveniently 第五句：chose→choose; with→on 第六句：likely后加to; worker→workers Ⅲ.书面表达 假定你是李华，你校将组织一次露天音乐会来为患重症的贫困生李明募捐，你是负责人之一。请你用英语给正在你市某大学学习音乐的美国朋友Anna写一封邮件，邀请她参加音乐会并表演节目。要点包括：‎ ‎1．写信目的；‎ ‎2．活动介绍(时间、地点、目的等)；‎ ‎3．期待回复。‎ 注意：1.词数100左右；‎ ‎2．可以适当增加细节，以使行文连贯；‎ ‎3．开头和结尾已给出，不计入总词数。‎ Dear Anna，‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ Yours，‎ Li Hua 参考范文：‎ Dear Anna，‎ I'm writing to invite you to take part in an openair concert to be held in the city square this Sunday and give a performance.
