I always wanted to know and learn new language, culture and tradition.At the beginning, because of the language prevention, going to canteen or restaurant or visiting places or buying things were a challenge. Later, when I began learning Chinese, considered one of the most difficult languages in the world, life became much smoother. In addition, I took part in after-school activities organized by the university or by Chinese friends. In the past four years I have visited many places in China such as Yichang, Beijing, Kunming and Sichuan province. I enjoy Chongqing's delicious hotpot, tofu, traditional Chinese tea. China covers a large region and has many ethnicities (少数民族), so there's a variety of Chinese food. China is a country with a time-honored civilization and a land of ceremony. Whenever guests visit, it is necessary to serve tea to them. Before serving tea, you may ask them for their preferences as to what kind of tea they prefer and serve them the tea in the right teacups.China is one of the few countries in the world which depend on coal as the main energy source. At present, coal accounts for about 70 percent of the energy structure in China, which produces serious environmental pollution and ecological (生态的) damage. After years of efforts, China has made achievements. Related technologies have been used in large companies in China.I'm lucky to here working as a doctoral researcher at the department of environmentalscience and engineering. I should have the opportunity to develop the knowledge and skills that I need to build a bright future planet. By gathering scientific knowledge in this field, I have plans to create new opportunities for policymakers of my country Bangladesh. I value the chance to serve my beloved homeland!4.The best title of the passage should be ________.A.the Chinese government helps less developed countries a lotB.Chinese, the most difficult language in the worldC.from Bangladesh to Chongqing, learning from ChinaD.Sichuan as well as Chongqing is home to delicious food5.We can know from the second paragraph that ________.A.buying things is a challenge in ChinaB.the writer probably wrote this article in 2019C.serving tea is necessary as tea is a healthy drinkD.the writer joined in after-school activities to meet new friends6.About the author (作者), we can know that ________.A.she majored in Chinese as a new language in Chongqing UniversityB.she considered Chinese as one of the most difficult languages in the worldC.she would work as a doctor to help the patients after she returned to her countryD.she loved her country, Bangladesh7.In the writer’s eyes, ________.A.China, like many countries, uses coal as the main energy sourceB.China is a country with much beautiful scenery and tasty foodC.environmental pollution will be a serious problem in ChinaD.China acts as the top country in the field of environmental science and engineering1. Do not drink up the tea at onceTea is not plain water, it can nourish (养育,抚养) your mind and keep you calm. If you’re not thirsty, then do not drink up the tea at once. On the one hand, it may be hot and bums your lips. On the other hand, it is generally considered a rude behavior. You should take a sip and appreciate the flavor, from good smell to sweetness till the long after taste, you may find words are too plain to describe this fascinating feeling and process.2. Do not spit the tea out of your mouthIt is also considered that the biggest impoliteness of the guest is to spit the tea out of mouth, especially, in front of the tea server. This bad manner may also leave a very bad impression on the host.3. Do not smokeSmoking cigarettes during the tea drinking is disrespectful. If you are a heavy smoker, you should ask the host for opinions. You should not start smoking unless the host or the hostess allows you to.4. Do not be absent-mindedKeep calm and relaxed when drinking tea, instead of being absent-minded and dispirited. Tea is not only an amazing drink, it can also be your friend.

“中国梦〞:中国新诗的历史源流一百多年来,中国诗人除了梦想着“合众旧诗国为一大新诗国〞,还身体力行地创作以中国现代化为主旨的现代诗,以及探究如何艺术表达中国现代化的意旨。
正是在这个意义上,我们可以说,中国新诗创作和理论探讨也是一个追寻“中国梦〞的艰辛历程。
由于不同时代诗人和同一时代不同诗人经验之不同,他们的梦想尽管各异其趣但又互为辉映,为我们创造出一个个诗意盎然的梦想世界。
“在诗人作出宏伟的发现时,一个诗的形象能够成为一个世界的萌芽,〞一个呈现于诗人的梦想前的想象天地的萌芽。
面对诗人所创造的这一世界,惊奇赞赏的意识油然而生。
〞那么,中国新诗诗人“宏大的发现〞以及在他们梦想世界里“诗的形象〞之呈现又是一幅幅什么样的图景呢?对中国新诗源头的勘探,我们要从晚清那里开始。
提到晚清诗歌革新,通常只讲“诗界革命〞。
实际上,在晚清诗界革命之前,还有一个我称之为的“诗文革新〞。
这场“诗文革新〞的主将是“剑气箫心〞的龚自珍和“忧患天下来世〞的魏源。
龚自珍看重诗歌的现实性、真实性和独创性,但他又坚守“夫诗必有原焉〞的诗观。
所以,当年谭嗣同就毫不客气地批评“龚魏〞“终身役于古人而已〞。
随后,由于国内涌动的改进运动、日本启蒙诗歌运动和中国古诗词内在规律变化等影响,大声疾呼“我手写我口,古岂能拘牵〞的黄遵宪,提倡并创作“新体诗〞“新派诗〞和“新诗〞。

Canada.BBarcelona's opera house has celebrated its reopening to the public since the coronavirus pandemic(新冠疫情)put the world into a huge horror,but their opening night had an unusual audience.For its first concert,the theater refused the usual crowd of people and instead packed the house with plants.Yes,that's correct.All 2,292 seats at the GranTeatre Liceu were occupied by green plants.The idea was conceived by an artist Eugenio Ampudia and was broadcast live on the theater's website.These lucky ficus trees,palms,and Swiss cheese plants-which were brought in by local nurseries(苗圃)-got the pleasure of hearing Puccini's Crisantemi performed by the UceLi Quartet string musical group.Ampudia hopes that his idea and the work will inspire people to think more deeply about their relationship with nature and the idea of sustainability(可持续性). "We are at the end of an era and that means that we have to change certain patterns," he shares. "We don't live in the same world as 90 days ago,and this means we have to reflect on everything that we do."As plants can respond to different vibrations(振动)caused by music,they certainly weren't a passive audience-even if they weren't able to give applause.Now that the concert is over,each plant will be given to a different frontline healthcare worker who helped guide the country through its battle with the coronavirus.The moving concert is a continuation of the Liceu's mission to create a dialogue between music and the visual arts.Pictures and a video of the performance taken by Ampudia will now become part of La Caixacon temporary art collection.4.What was the special part of the concert?______A. It had only 2,292 seats.B. It made the world fall in horror.C. It welcomed audience with plants to come.D. It gave plants opportunities to enjoy music.5.What does the underlined word "conceived" mean in the second paragraph?______A. hatedB. enjoyedC. put forwardD. turned down6.Which statement may Eugenio Ampudia agree with?______A. We didn't do very well in dealing with nature.B. The healthcare workers were more important.C. The plants should have the equal rights.D. We did everything in a wrong way.7.In which column(专栏)of a magazine can this text be read?______A. Daily Hero.B. Teens' Life.C. New Technology.D. Art Around the World.CTwo pig farmers in Suffolk,East England have succeeded in feeding one million bees after participating in a project that saw them turn over half of their land to wildflowers.Four years ago,brothers Mark and Paul Hayward decided to fill 81 acres of their farm land with wildflowers.This week,a study was carried out monitoring insect activity on theflower-covered land,which found they were feeding one million bees at any time."This was our target when we started,to grow enough flowers to feed a million bees on a single day." Mark said. "We are acutely aware that bees are under threat from modern farming methods and that East England is one of the worst places where bees are seriously suffering from lack of foraging diversity(觅食多样性)," he continued."Every third bite of food you eat can come from bees and we wanted to create an operation on our farm that did not push nature out but rather hugged it-as a central part of our ecology system and our food cycle," he said.The farm uses all kinds of seeds which can produce many different wild plants and of course,the bees can get food from different wildflowers."We are taking a very small role in helping society restore a balance and this starts with plant diversity to encourage insects,bees,small mammals(哺乳动物),and birds," said Paul. "At the end of the day,we see ourselves as caretakers of this land.Between us we have six children and we owe it to them to farm sustainability(持续性)and set an example for the generations to come," added Paul.According to the Bee Conservation Trust,many types of bees have seen their populations decline by 70%,and two species have become extinct in the last century.Gill Perkins,CEO of the Bee Conservation Trust said,"Thanks to Mark and Paul,at least here,1 million bees can keep living,which is of great significance for ourselves now and future."8.What can we know about the brothers from the first two paragraphs?______A. They have about 160 acres of land.B. They grow wild flowers for pigs.C. They are not good at growing wild flowers.D. They have to support 1,000,000 bees in their land.9.Why are bees under threat in East England?______A. There is not enough food for bees.B. Bees are not used to the modern society.C. There are too many animals eating bees.D. Bees can not find different wild flowers.10.What is the Gill Perkins' attitude to the action?______A. Opposed.B. Doubtful.C. Supportive.D. Disappointed.11.What is the best title for the text?______A. The Bees are in Danger NowB. Two Brothers Feed a Million BeesC. One Million Bees are Surviving in East EnglandD. Two Brothers Love Wild Flowers in East EnglandDAs we know birds do not have teeth.However,according to a new study,this was not always the case.About 116 million years ago,the ancient birds had teeth and used them for eating,just like what they do today.The new study was conducted by a team of researchers that analyzed the remains of the tooth gene in modern birds and tried to find out why the teeth suddenly disappeared in birds during the process of evolution.Because the fossils of ancient birds,buried deeply in the earth,are either broken or not preserve (保护)well,their use in determining this evolutionary(进化)change has not been helpful.Researchers have instead focused on analyzing the DNA of modern birds.The aim of the study is to search for clues in the genes of birds that explain the loss of teeth during evolution.In the absence of teeth,birds heavily rely on their beaks(鸟嘴)to process food.They also have an excellent ability to digest the food properly.However,at some point in history,birds used torely on their teeth for chewing(咀嚼)food just like us.The earliest known clue in this regard was found in Germany in 1862.The fossil of an ancient bird found there,suggested that birds had teeth in the past.Today,scientists have confirmed(确认)that birds evolved form dinosaurs that were known for their sharp and pointed teeth. Until now,there has been no definite explanation of the significant evolutionary change in birds.In the ongoing study,researchers analyzed the genes of modem birds that are responsible for tooth production.They searched for any kind of genetic mutation(基因突变)that may have made the gene to become inactive.The gene mutation first occurred about 116 million years ago.12.What does the underlined word "fossils" mean in Paragraph 2?______A. A kind of bodies which are still full of life now.B. A kind of stones which were from ancient animals.C. A kind of animals which were relatives to modern birds.D. A kind of ancient dinosaurs which hid deeply in the earth.13.How did the researchers do the study?______A. By studying the DNA of modern birds.B. By studying the functions of birds' mouth.C. By comparing the dinosaurs and the birds together.D. By visiting Germany to get the newest information.14.What is the researchers' attitude to the conclusion?______A. Uninterested.B. Disappointed.C. Convinced.D. Unsure.15.What is the best title for the text?______A. The Ancient BirdsB. The Ancient Birds Have TeethC. The Ancient Birds Are like HumanD. The Birds Abandoned the Teeth Now二、阅读七选五(本大题共5小题,共10.0分)No matter how well you do in an interview,arriving more than a few minutes late for a job interview is likely to have a negative effect on an employer's impression of you.

But culturally speaking, Paris was probably the least logical choice. This is because France is known for its reputation of smirking(自鸣得意地笑)at anything about Americans—an attitude called "anti-Americanism".However, Disney opened a park in Paris 1992 anyway. How has it managed to survive for so long in a country that some thought may not welcome it?According to National Public Radio, "America creates a danger to everything the French value highly." For example, France is famous for its fancy cuisine(菜肴)and people there usually spend a long time over meals. But American fast food—hot dogs and hamburgers, to name two—introduced a completely different dining style. And in the film industry, while French culture values low-plot and high-art films, Hollywood's fast-food-style film productions may seem of low taste in the eyes of the French."In the land of Louis XIV's real Castle of Versailles...why do we need the fake one of Sleeping Beauty?" This is the reaction of many French people toward the US theme park, according to The Baltimore Sun Newspaper.There used to have doubt over whether the Disney magic would work in France. But this doubt has been proved unnecessary now that the park has been standing for 25 years. And according to The Telegraph, Disneyland Paris was visited by nearly 15 million people last year, half of whom were French."France is changing. Slowly, its way of life is beginning to resemble(与……相似)that of the country it loves to hate," commented The Economist.Today, even though French people are still seen as "cold" and proud of their own culture more than anything, they are already part of the trend of globalization and there is nogetting out of it."At the core, America gives us the same effect as ice cream." French journalist Jacqueline Remy once wrote in L'Express magazine. "It makes us sick, but we keep asking for it."(1)What is the article mainly about?A.How French people hold an "anti-American" attitude.B.A look at France's changing attitude toward US culture.C.The characteristics of French people and their unique culture.D.How Paris was the perfect location for Europe's first Disneyland.(2)What are the examples in Paragraph 3 used to show?A.French people have a better taste in films.B.France is famous for its cuisine and movies.C.American culture is important to the French.D.American culture may threaten French culture.(3)Which of the following statements is true about Disneyland Paris according to the article?A.Most French people refuse to visit it.B.It mixes American and French cultures.C.It is a popular tourist attraction for the French.D.It was designed to look like the Castle of Versailles.(4)What can be concluded from the last three paragraphs?A.French people are no longer proud of their own culture.B.French people are completely open to American culture.C.Most French people consider globalization a bad influence.D.American culture is having an influence on French people's lives.3.When early automobiles first arrived on the scene in the late 19th century, few people could have imagined that they would one day take over the world. In fact, some towns found the noise and exhaust(排气)from these novel "horseless carriages" so off-putting(令人厌恶)that early cars were actually forbidden in some places.In time, of course, restrictions were lifted and the car soon became ubiquitous across the country. But there is still one place in the United States that has yet to change its mind. Thatis Mackinac Island, where cars have been banned since 1898.Located just offshore of mainland Michigan. in Lake Huron, Mackinac Island and its namesake(同名)city have long been a favorite spot for a relaxing getaway. So, when automobiles first began to arrive, loud noise and terrible smoke made the locals angry. It quickly became apparent to the locals that this new invention was not for them.Naturally, in 1898, the Mackinac village council(议会)decided to forbid the automobile before the monsters had a chance to take over. So what is life like in place where one of the most influential inventions in history has been banned? Well, it's quite nice, actually.Although the small island is home to only around 500 people, in the summer, that number swells to 15,000 during tourism season; aside from a couple of emergency vehicles, there's no car to be seen. Transportation on Mackinac is limited to walking, horse-drawn carriages, and bicycling, a pleasant escape from the car-centric society that exists beyond its borders."The air is cleaner and injuries are fewer," writes Jeff Potter, who published an article about Mackinac. "Island citizens are healthier due to the exercise. There' s a cherished egalitarianism(平等): everyone gets around the same way. They also save a huge amount of money that would normally go to commuting(往来)by cars."(1)What does the underlined word "ubiquitous" probably mean?A.Present.B.Absent.C.Dangerous.D.Difficult.(2)Why were cars banned on Mackinac Island?A.There wasn't enough space on the island.B.The locals wanted to improve the tourism.C.The locals hated noise and smoke from cars.D.Cars might cost the locals too much money.(3)What can we infer from the text?A.Too many people are living on the island.B.The tourism is developing very well on Mackinac.C.Transportation on Mackinac is limited to walking.D.Cars are allowed to travel on the edge of the island.(4)What means of transportation is forbidden for travelers to Mackinac Island?A.On emergency cars.B.In horse-drawn carriages.C.On foot.D.By bike.4.If you want to get something done, you might want to put your mobile phone back in your pocket. Researchers have found that the mere presence of a phone is distracting(干扰的)—even if it is not your own. And the devices are likely to distract you, even if they are not ringing or "pinging" with text messages. People asked to carryout electronic tests of their attention spans(持续时间)were found to perform worse when a mobile phone was present than other people performing in the presence of a paper notepad.Scientists from Hokkaido University in Japan said that their findings show that it is harder to concentrate when one of the electronic devices is present. The effect was most marked on people who are not regular users of phones. In tests on 40 undergraduates, Associate Professor Junichiro Kawahara and a colleague divided the subjects into two groups—one asked to carry out tests in the presence of an Apple iPhone next to a computer monitor, and the others in the presence of a notebook.The test involved asking the participant to search for a particular character among a mess of other characters on the screen. Researchers measured the time it took to find the target. The results of the experiment found that those with the mobile phone took longer to find the character "indicating that participants were automatically distracted by the presence of the phone". The researchers suggest that people are "drawn to the presence of a mobile phone" although there are individual differences in how one attempts to ignore it. In conclusion. Professor Kawahara said, "The mere presence of a mobile phone was a distraction among infrequent internet users."Another finding is that listening to one half of a mobile phone conversation also distracts people, and other studies have found that placing a mobile phone in view has a negative effect on the quality of face-to-face communications. Holding a mobile phone makes you less likely to get a fair hearing from others.(1)What is the first paragraph mainly about?A.A mobile phone won't distract people unless it's ringing.B.A paper notepad can help people record much information.C.Text messages distract people even if phones are power off.D.People find it hard to concentrate if their phones are present.(2)Who will be affected most according to the findings?A.People irregularly using phones.B.People regularly using phones.C.People usually using notepads.D.People always using computers.(3)In a face-to-face communication, what is the effect of putting a mobile phone in sight?A.It makes listeners feel much awkward.B.It causes other people to lose respect for you.C.It reduces people's attention to listening to others.D.It makes the air of the conversation more pleasant.(4)What can we infer from the text?A.People perform worse with a mobile phone at hand.B.Mobile phones do a lot of damage to people's health.C.People working with mobile phones will do very well.D.Phones should be banned in all schools and universities.二、七选五5. 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。
