材料一：拉美魔幻现实主义上世纪八十年代在中国的登陆，除了作家们以开放的胸襟和创新的热望去自觉汲取外，他们知识结构和文化素养中的传统文学因子的迎合也是不可忽视的。

中国传统文学本身就具有对拉美魔幻现实主义的认同空间。

中国本来就有着极悠久的魔幻文学传统，中国文学中的志怪一脉源远流长。

拉美魔幻现实主义译介进来以后，骤然契合并接通了中国已有的魔幻文学的审美旨趣。

使中国作家很容易从心理上认同与接纳它。

作家汪曾祺曾说“中国是一个魔幻小说大国，从六朝志怪到《聊斋》，乃至《夜雨秋灯录》，真是浩如烟海。

”中国确实有自己的魔幻文学传统。

中国古代的魔幻文学主要由志怪小说和神魔小说组成。

追溯起来，中国的志怪小说和神魔小说的始祖应该是神话《山海经》。

《山海经》是中国第一部集中记录神话片断和原始思维的奇书，书中历述怪兽异人的地域分布和由此产生的神话和巫术幻想，其中有不少人神禽兽虫鱼异类合体的神奇想象，如人面鸟身，人面鱼身等。

西汉末年，因刘歆校定《山海经》，激起一股志怪小说的写作热潮，出现了托名东方朔的《神异经》《十洲记》等。

到了魏晋南北朝时期，志怪小说越发盛行。

主要有干宝的《搜神记》等。

在这些志怪小说中，写到了人鬼之间、人神之间、人与异物之间的种种变化互生，充满了神秘色彩，如《搜神记》“韩凭夫妇”写韩凭夫妇的精魂化为相思树和鸳鸯鸟的故事。

在唐代主要是中、晚唐，以志怪述异为特色的作品有《玄怪录》《续玄怪录》，在宋代则有洪迈的《夷坚志》等。

《夷坚志》记录了两宋之际政局变乱的怪异征兆，以及人们神神鬼鬼的生活，它把历史和虚幻、人事和怪异相交织，语多怪力乱神。

明代吴承恩的《西游记》是我国最伟大的神魔小说，它将玄奘取经的真实事件杂以神奇传说和佛教故事，描绘了一个光怪陆离的神话世界。

Pour a dollop （团）of lead into cold water and the shape it dorms may be telling you about the year to come. A heart shape, naturally, means love will come your way. A crown predicts wealth and fortune. A star indicates happiness. But if you see a cross, you're almost dead!Latin AmericaIf you are in Latin America, make sure you have some colourful underpants to ring in the New Year. End — of — the — year partiers put on colourful underwear to ensure certain types of outcomes of the following year, red for love and yellow for success.Naples, ItalyNeapolitans like throwing things out of the windows, at least on New Year's Eve. Furniture, kitchen machines, grandma.. Well, maybe not the last one. Let's hope not, anyway. This tradition is meant to symbolize an out — with — the — old gesture and get a new beginning of the new year. These days people are a bit more mindful of what they throw into the street below.SpainIn 1909, winegrowers in the Alicante region of Spain had a brilliant idea: Start and promote an annual tradition that would involve people in having to buy and eat more grapes. Everyone must eat 12 grapes on New Year's Eve to pray for wealth of the coming year. Now, it's a popular custom in Spain. But the problem is that people have to eat a grape for each bell striking at midnight.1．Germans would like to see the following shapes of lead Except ________.A．a heart B．a crossC．a star D．a crown2．What can we know about Neapolitans’ tradition?B．They are more careful about what to throw now.C．They throw their grandma out of the window.D．They like making gestures in front of the windows.3．In order to have wealth of the coming year, what do people in Spain do?A．They buy lots of wine.B．They pray with 12 grapes.C．They eat as many grapes as possible.D．They eat a grape for each bell striking,Once upon a time, a daughter complained to her father that her senior high school life was unhappy and that she was tired of struggling with homework all the time.Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire. Once the three pots began to boil, h placed potatoes, eggs and coffee beans in them. After 20 minutes, he took them out, putting the potatoes and eggs in a bowl and the coffee in a cup.Turning to his daughter, he said, “Look closer, and touch the potatoes.” She did and noted that they were soft. He then asked her to take an egg and break it. After puling off the shell, she observed the hard-boiled egg. Finally, he asked her to taste the coffee. Its good smell brought a smile to her face.“Father, what does this mean?” she asked. He then explained that the potatoes, the eggs and the coffee beans were in the same adversity (逆境)—the boiling water. However, each one reacted differently.The strong and hard potato became soft and weak in boiling water. The egg was fragile, with the thin outer shell protecting its liquid until it was put in the boiling water. Then the inside of the egg became hard. However, the coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new. “Which one do you want to be like,” he asked. “When adversity knocks on your door, how will you respond?”In life, challenges happen to us all, but the only thing that truly matters is what happens within us.4．Why did the girl complain to her father?C．Because of her father’ s busy work.D．Because of the food her father cooked. 5．What can we infer from this story?A．The girl liked the coffee best.B．The father was good at cooking.C．Different people have different reactions to adversity.D．The girl didn’t like the potatoes and eggs.6．What does the underlined word “fragile” mean in the 5th paragraph?A．thick B．hard C．strong D．easily-broken 7．What would be the best title for the passage?A．Challenges and responses.B．Adversities and a chef.C．A chef and coffee beans.D．Father and daughter.Teenagers who start the school day really early are likely to weigh slightly more than those who start later. That's the finding of a new study of nearly 30,000 Canadians between the ages of 10 and 18.Getting too little sleep can put kids at risk for a number of problems. Sleepy teens are more likely to be overweight, to have trouble concentrating and to struggle in school. Genevieve Gariepy, who works at McGill University in Montreal, Canada, wanted to know how earlier school start times night be connected with weight."Overweight in teenagers is a big problem in North America," she says. The number of overweight kids has grown over the past 30 years. About one in three American and Canadian teens are now overweight. Kids who don't sleep enough may be at higher risk. So Gariepy decided to focus on the impact of school start times.Her team collected start times for 362 Canadian schools. Then they asked students at those schools to give their height and weight. In all, they collected data from nearly 30,000 10-to 18-year-olds. Among 6th-to 10th-graders, those who started school earlier were likely to be slightly heavier for their height. Every 10-minute delay in school start time was connected, on average, with a slightly lower weight among students who were the same sex, age and height. However, the difference is slight. Healthy eating and getting enough exercise will play a bigger role in keeping a healthy weight.Because the study compared kids who already started school at different times of day, it'ssure, researchers would want to compare the same kids before and after changing to a later school start time.Still, the study is a good start, says Cora Collette Bruener, a doctor at Seattle Children's Hospital in Washington. The findings add to a growing pile of evidence that later school start times might be better for teen health, she says.8．What is the finding of the new study?A．More and more teens are growing overweight.B．Healthy diets and enough exercise help reduce weight.C．Teens who start school earlier are a little overweight.D．Teens who start school earlier do not perform well.9．To keep a healthy weight, teenagers need______________.A．much sleep B．earlier school start timeC．less sleep D．a balanced diet and enough exercise 10．How did Gariepy's team get their findings?A．By recording the teens' weight.B．By checking the teens' physical health.C．By comparing different sets of data.D．By measuring the teens' height.11．What does Cora Collette Bruener think of the study?A．It has inspiring value.B．It lacks further support.C．It needs improving D．It is well designed.China has been planting seaweed for about 1,700 years . Coastal populations harvested a variety of algae first as a source of food and animal feed, but later for industrial and nutritional purposes as the practice became more widespread-Today, China remains the world’s biggest producer of farmed seaweed, but many other countries start to realize the potential of planting seaweed.Certain red seaweed varieties contain up to 25% protein, but others are also rich in iron and other minerals. Seaweed planting becomes hot aquaculture which is now shooting up. In Alaska, where the largest seaweed farm in North America is located, farmers produced over 112,000 pounds of seaweed in 2019 — a 200% increase from Alaska’s first commercialsimple and comes with a lot of environmental benefits.Research shows that seaweed could play a key role beyond serving as a source of nutrients and food, but also in the fight against some of the worst problems: climate change and ocean pollution. Seaweed doesn’t need to be fed or fertilized, as the crop gets everything it needs from sunlight and the natural nutrients already found in the ocean water. There are, of course, some disadvantages to seaweed farming. For example, overproducing seaweed could influence the amount of natural light available to other ocean species. In addition, technology for transporting, drying, and turning seaweed into biofuel and food can take up resources and give off CO2. It’s also possible that these crops could remove too many nutrients from the wild ecosystem.However, as research continues to search into sustainable seaweed farming methods, we may discover that advantages win over disadvantages.The economic value of dealing with nutrient pollution, for example, may reduce costs for wastewater treatment; the same goes for turning seaweed into biofuel, fertilizer, or fuel depending on water quality. The balance will come down to a combination of policy and scientific research .12．Why does the author mention seaweed farming in Alaska?A．To show seaweed planting is growing fast.B．To announce seaweed planting is eco-friendly.C．To state seaweed is easy to plant across the world.D．To prove seaweed planting has large economic benefits .13．Which is the disadvantage of seaweed planting?A．Removing other ocean species.B．Consuming too many nutrients.C．Taking up too much space.D．Causing potential ocean pollution. 14．How is paragraph 3 mainly developed?A．By making a comparison.B．By providing evidence.C．By using classifications.D．By analyzing the background. 15．What can we infer about seaweed farming in the last paragraph?A．There are arguments over it.B．Turning seaweed into fuel is necessary.C．It needs joint efforts to improve.D．Dealing with nutrient pollution costs a lot.How similar are language and music?Language is part of our daily lives, no matter where we live in the world. 16 Both language and music play a huge role in our culture and here are some of their similarities.Both language and music have a writing system.In English we record language using the alphabet, which is a collection of letters. Similarly, we use notes (音符) to keep a record of music. Musicians read notes and create meaning in the form of music. 17 By writing pieces of text or music, we are able to share experiences through time. We can read the ideas or hear the composition (作品) of someone who lived hundreds of years ago.18You can make a good guess at where someone is from by listening to the language he uses. In the same way, we know that styles of music are different around the world, giving us the opportunity to explore many different cultures through their music and providing us with music for every situation.Both share emotion.19 Of course you may be able to see it in my face, but you will know for sure through my words. Similarly, music can sound angry, sad or happy. Music can show you exactly how the composer was or is feeling, and allows us to share that emotion. When you feel happy, you might want to sing and dance to a happy song to celebrate your happiness.20 I think we have all used music to express or process our emotions, often combining it with language in the form of song lyrics (歌词).A．Both are expressive.B．Both vary with culture.C．How do you know that I am angry?D．We use language to express our thoughts.E．Similarly, music is part of many people’s lives.F．So just as you read English, you can read music.G．In contrast, you probably also listen to sad music when you are feeling down.25．A．throwing B．losing C．leaving D．dropping 26．A．Though B．While C．Since D．Because 27．A．opinions B．statements C．comments D．discussions 28．A．determined B．attempted C．pretended D．managed 29．A．kept away B．took back C．put away D．held back 30．A．garden B．market C．church D．library 31．A．escaping B．missing C．delaying D．stopping 32．A．uninterestedly B．uncertainly C．unfortunately D．unexpectedly 33．A．changes B．friends C．efforts D．decisions 34．A．struggled B．competed C．dealt D．lived 35．A．run B．play C．chat D．walk 36．A．along B．across C．by D．in 37．A．oneself B．myself C．herself D．itself 38．A．relive B．remind C．relate D．rethink 39．A．excited B．upset C．proud D．regretful 40．A．exist B．stretch C．lead D．stay四、用单词的适当形式完成短文阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
