ADespite the lack of new releases due to the outbreak of COVID-19, there was no shortage of good films in 2020. We've rounded out the top 4 films. Check them out!SoulIn the first Pixar cartoon to have an African-American lead character. Jamie Foxx provides the voice of a music teacher who dreams of making it as a jazz pianist. But just after a successful interview, he falls down a manhole and finds himself in a soul world where human spirits are assigned their personalities. And things get even stranger from there.NomadlandWhen Fern loses her husband and can't afford to live in a house, she packs her few belongings into a camper and drives off into the Nevada desert. She encounters a large community of senior citizens who have also been forced to live on the road, supporting themselves with short-term- jobs along the way. What makes Nomadland unique is that while Fern is played by an Oscar-winning actress, nearly all she meets are real people who relate their own experiences. Written and directed by Chloe Zhao, the film is a combination of documentary and fiction.The Croods: A New AgeThe prehistoric family from 2013's hugely enjoyable cartoon, The Croods, directed by Joel Crawford, makes a welcome return, so we can expect more crazy adventures and unusual animals. Inthe much-delayed- sequel, they meet another family, the Bettermans, whose advanced lifestyle and technology make the Croods look even more primitive than they did already. There's conflict but they learn to appreciate each other's differences.WolfwalkersThe year's finest cartoon film comes from Cartoon Saloon, an Irish studio specialising in stylised hand-drawn 2D art. Its latest production is set in the mid-17th Century, when English soldiers are trying to occupy the wild woods.

黑龙江省佳木斯市第一中学2024-2025学年高二10月考试英语试卷一、阅读理解Innovation might sound like a technical and complicated process. However, some innovations have been born out of the most unbelievable and straightforward ways like nature. There have been many nature-inspired innovations, and below are several innovations that have shaped our world.The “Velero (尼龙粘扣)” fastenerIt was invented when a Swiss man named George de Mestral went for a walk with his dog in the woods and thought the burrs (芒刺) that clung to his trousers could be turned into something useful. He came up with the idea of making hook-and-loop fastener often called “Velcro” and patented his design in·1955. Hook-and-loop fastener is essential in medical equipment, shoes, and sports equipment. NASA’s astronauts used it in the 1960s to fasten their equipment.Self-cleaning surfacesIn order to create surfaces that do not require human effort to keep clean, Wilhelm Barthlott drew inspiration from a lotus leaf to create self-cleaning surfaces. They discovered that the lotus leaf is considered hydrophobic (不易沾水的) because of its double-structured surface made of the cuticle and wax. The wax increases the leave’s contact angle which gives it its self-cleaning ability. This fantastic innovation has since been applied in the mirror industry and the making of tiles (瓷砖)and windows. New high-rise buildings also use self-cleaning windows.Bullet train that produces less noiseA Japanese team was inspired by the kingfisher to design a bullet train that produces less noise. A group of .engineers realized that the kingfisher’s bill shape is like a wedge (三角木), an ideal shape to help the bird break up air and water out of its way, therefore, making no noise as it travels through the water. The team went back to work on the train’s shape to resemble that of the kingfisher’s bill, and it worked! This innovation not only reduced the amount of noise produced but also reduced the amount of energy used in the process by 15%, and also the speed increased by10%.1．The invention of hook-and-loop fastener was inspired by ________.A．a kind of dog B．a kind of plant C．a trip of walk D．a kind of bird 2．Where may you find Wilhelm Barthlott’s invention?A．On your shoes.B．On your schoolbag.C．On your sports equipment.D．In your bathroom.3．What do the three inventions have in common?A．They are invented by Japanese.B．They draw inspiration from nature.C．Their shapes are similar to each other.D．They hardly have any effect on people’s life.Face masks and protective suits can save lives. But what happens after people are done using them? Binish Desai, the founder of Eco-Eclectic Technologies from Western India, saw the impact brought by the rising use and demand for single-use masks and kits due to the coronations pandemic (冠状病毒流行病), so he created Brick 2. 0 to prevent tons of single-use Personal Protective Equipment (PPE) from being waste and ending up in landfills or water streams.Although PPE is essential for medical use, it is extremely necessary to assess new alternatives and to raise awareness regarding its proper use and disposal (处理). A study published by the American Chemical Society suggests that 129 billion face masks are used monthly during the coronations pandemic, which causes great environmental pollution. In India alone, over 18, 000 British tons of coronations-related biomedical waste was generated in just four months between June and September. The waste would take hundreds of years break down, according to the magazine Waste Advantage.Brick 2. 0 is a new version of the brick made from industrial waste, now also including used face masks and protective suits. The process starts with the collection of PPE waste through garbage cans placed in small shops and apartment buildings, with easy access for people to throw away their used items. Once in the factory, the collections are kept for 72 hours for safety reasons. Then they are cleaned and torn into pieces before being mixed with other waste. Finally, the material is shaped, and once dry, each brick is ready to use. It is three times stronger thanconventional bricks at twice the size and half the price.In a complex circumstance like the one we are living in these days, this solution is not only relatively easy to operate, but also very achievable in the short term, which can really help overcome today's global environmental challenges.4．Why did Desai create Brick 2.0?A．To recycle the PPE waste.B．To reduce production cost.C．To protect water recourse.D．To prevent serious disease.5．What do the figures in Paragraph 2 indicate?A．The study lacks sufficient evidence.B．The pandemic is difficult to control.C．The demand for face masks is in decline.D．The environment is facing severe challenges.6．What is mainly discussed about Brick2.0in Paragraph3?A．Its function.B．Its advantage.C．Its main characteristic.D．Its production process.7．What can be a suitable title for the text?A．Innovation never endsB．Environmental issues countC．Transform waste into treasureD．Defend your life with face masksTripadvisor, one of the world’s most popular travel sites, has recently announced that it will stop selling tickets to attractions that have captive(囚禁的) whales and dolphins. The ban(禁令) is a continuation of the company’s 2016 policy that banned sales of tickets to attractions where tourists come into physical contact with animals, like elephant rides.“Whales and dolphins do not grow well in limited captive environments,” Dermot Halpin, aTripadvisor spokesperson, said. “We believe the current generation of whales and dolphins in captivity should be the last, and we look forward to seeing the whole travel industry follow this position.”The ban applies to all attractions and aquariums(水族馆) that employ whales and dolphins for public displays.“Our aim is to stop future generations of whales and dolphins from being raised in captivity, and we hope to see them live freely in the wild,” Halpin said.Not everyone liked the decision. Sea World, a top attraction in Florida, said the move ignored the needs and preferences of the general public. “I think Tripadvisor’s new decision was made in opinion rather than in science and research. It ignores the educational value of zoos and aquariums. Tripadvisor should trust its customers to make well-informed decisions,” said a Sea World spokesman. “Sea World always takes good care of all animals, including whales and dolphins. Sea World will continue to put more efforts in education and animal protection.”Tripadvisor, which serves an average of about 490 million travelers a month, said the new policy will go into full effect by the end of the year.8．What stopped dolphins and whales growing well according to Dermot Halpin?A．Too limited space.B．Unhealthy food.C．Lots of public displays.D．Too much training.9．What does the underlined part “this position” in Paragraph 2 refer to?A．Stopping employing captive dolphins and whales.B．Tourists coming into physical contact with animals.C．Whales and dolphins living in captive environments.D．The current generation of whales and dolphins in captivity.10．Where did Tripadvisor hope dolphins and whales would live in the future?A．In aquariums.B．In protected areas.C．In unpolluted oceans.D．In the natural environment.11．How did Sea World feel about Tripadvisor’s decision?A．Puzzled.B．Proud.C．Unconcerned.D．Disappointed.There’s no place like home, where we’re surrounded by our favourite foods and many other comforts. Most important of all, we can keep adding favorite things to give our homes a personal touch. 12Of course, we can be easily attracted to these unique plants. They can add a natural touch to our homes. 13 According to the Royal Horticultural Society, nearly 72% of adults in the UK have some houseplants in their homes, and a fifth of adults say they use plants in their homes to make them feel happier.14 The reason is that more and more young people are living in flats without a garden. One of those interviewed is 24-year-old Daisy Hale. She said, “Being able to beautify the small room without having to spend too much is perfect for me.”Despite the benefits, the Royal Horticultural Society is deeply concerned that the houseplants might not be good for the environment. 15 These foreign plants might be very harmful to our environment. It is also worried about the plastic pots that hold the plants and the type of peat (泥炭) that the plants are grown in.In short, the Royal Horticultural Society encourages people to buy local plants held in reusable pots that are filled with natural soil. 16A．Some of those popular things are houseplants.B．However, some of these houseplants are too expensive.C．Many experts are opposed to buying houseplants for homes.D．Many of the plants bought online are shipped from overseas.E．Young people are driving up the sales of houseplants very fast.F．They have the ability to brighten up a room with acceptable costs.G．Then these “living” additions will be good for ourselves and for our environment.二、完形填空Ariel Cordova-Rojas rode her bike to Jamaica Bay Wildlife Refuge in Queens, New York, planning to go hiking and bird-watching.

《大学英语II》期末预测试卷No.3（附答案）重庆交通学院《大学英语II》期末预测试卷No.3Part I Listening Comprehension (20%) （略）Part II Reading Comprehension (40%)Directions:There are 4 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage 1Questions 31 to 35 are based on the following passage:Every year about 10,000 people in the United States die from severe burns. Severe burns allow the loss of water from the body. Once the protective covering of the skin is gone, the body is also in great danger of bacterial infection. When someone has been burned, the most important first step is to close the wound. The best way to close the wound is to transplant (移植) skin from another part of the victim’s body. Unfortunately, some burns affect such a large area that transplanting the patient’s own skin is not possible.Fortunately, chemical engineers have recently developed a new product to help burn victims. This product is artificial (人造的) skin. Artificial skin can quickly cover and protect large areas of burned skin. Artificial skin is a two-layer material made of tissue (组织) from cattle. It is only two hundredths of an inch thick. This material guards against infection and the loss of fluids while the patient’s skin grows back.Over small wounds, artificial skin is eventually shed (脱落) as the natural skin underneath heals. Over larger wounds, theartificial skin lasts up to 40 days before it breaks down and a new one must be used. Artificial skin may help save the lives of thousands of burn victims?3l. What is the damage of severe burns to burn victims?A. The body is more likely to be infected with bacteria.B. They leave some scars (疤) on the skin.C. The tissue underneath the skin is damaged.D. They upset blood circulation (循环).32. When someone has been burned, it is of vital importance to________.A. remove the damaged skinB. take some medicine to ease the painC. clean the infected woundD. close the wound33. Why is it necessary to transplant artificial skin instead of their own skin for some burnvictims?A. Because artificial skin is more nutritious.B. Because it costs less to transplant artificial skin.C. Because the burn wounds are very large.D. Because transplanting artificial skin saves much time.34. Which of the following is one of the features of artificial skin?A. It is sensitive.B. It is thin.C. It has life-long.D. It looks similar to the natural skin.35. The word “fluid” (Paragraph 2, Line 4) means _________.A. waterB. protectionC. energyD. bloodPassage 2Questions 36 to 40 are based on the following passage:If parents bring up a child with the sole aim of turning the child into a genius (天才), they will cause a big problem. According to several leading educational psychologist, this is one of the biggest mistakes which ambitious (雄心勃勃的) parents make. Generally, the child will be only too aware of what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children.However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a reasonable way, the child may succeed in doing very well —especially if the parents are very supportive of their child.Michael Lee Chao Tin is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers a wee k for violin lessons. Although Michael’s mother knows very little about music, Michael’s father is a good trumpet (小号) player. However, he never makes Michael enter music competitions if he unwilling.Michael’s friend, Winston Chiu Fang Weng, however, is n ot so lucky. Although both his parents are successful musicians, they set too high a standard for Winston. They want their son to be successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. “When I was your age, I used to win every competition I entered,” Winston’s father tells him Winston is always afraid that he will disappoint his parents and now he always seems quiet andunhappy.36. Which of the following mistakes are parents likely to make according to the passage?A.To neglect their child’s educati on.B.To help their child to be a genius.C.To make their child become a musician.D. To expect too much of their child.37. What should parents do in order to help their children succeed?A.They should understand and help their children in difficult times.B.They should try to have their own successful career.C.They should arrange private lessons for their children.D.They should push the children into achieving a lot.38. Which of the following statements about Michael Lee’s parents is true?A. His father is a very poor player of trumpet.B. His parents help him in a proper way.C. His mother knows much about music.D. His parents are quite rich and have a car.39. Winston’s parents push their son so much that __________.A.he has already become a better musician than his fatherB.he has succeeded in a lot of competitionsC.he feels he cannot learn anything about music from themD.he is unhappy because he is not self-confident40. The two examples illustrate the principle that _________.A. parents who want their child to be musical should also be good musiciansB. successful parents often have unsuccessful childrenC. it is important to let children develop in the way they wantD. the more money spent on a child’s education, the better the child will doPassage 3Questions 41 to 45 are based on the following passage:To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun!Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high office.In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And it was considered a symbol of power and authority. By 1680 the umbrella appeared in France, and later on in England.By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn’t until the twentieth century thatwomen’s umbrella began to be made, in a whole varie ty of colors.4l. According to this passage, the umbrella was probably first invented ________.A. in ancient ChinaB. in ancient EgyptC. in ancient GreeceD. in ancient Rome42. Which of the following statements is not true about the umbrella?A. No one exactly knows who was the inventor of the umbrella.B. The umbrella was first invented to be used as protection against the sun.C. The umbrella changed much in style in the eighteenth century.D. In Europe, the Greeks were the first to use the umbrella.43. A strange feature of the umbrella’s use is that it was used as ________.A. protection against rainB. a shade against the sunC. a symbol of honor and powerD. women’s decoration44. In Europe, the umbrella was first used against the rain ________.A.during the Middle AgesB.by the eighteenth centuryC. in RomeD. in Greece45. This passage talks mainly about ________.A. when and how the umbrella was inventedB. why the umbrella was so popular in EuropeC. the development of the umbrellaD. the history and use of the umbrellaPassage 4Questions 46 to 50 are based on the following passage:The story you are about to read is almost unbelievable, but it is true. It happened one winter’s night in 1944, during World War II. Airplanes of the Royal Air Force, after dropping their bombs on Germany, were on their way home.In each plane, men looked anxiously over their guns into the darkness. This was the time when enemy fighter planes might attack. One of the air-gunners was Nick Alkemade. He was a gunner in the back of the plane and he sat in the rear-gun position, at the very tail of the plane. It was so small that before climbing in, Nick had taken off his parachute(降落伞) and left it in another part of the plane. He felt more comfortable without it. Soon, however, he began to feel very uncomfortable indeed. Suddenly there was a terrible explosion and the whole aircraft shook. The whole of the middle part of the plane burst into flames and Nick heard the captain shout, “We’re on fire! Jump!”At first Nick could not get out of his seat. The tiny door was stuck. After struggling with all his strength for several moments, he forced it open. He could stay in the plane and be burnt to death or he could jump without a parachute and be smashed to death, after falling 6,000 meters. He jumped!The cold air hit him and he could not breathe. At this height the air is too thin to breathe properly. As Nick began to lose consciousness, he thought, “So this is what it’s like to die.” Thenhe remembered no more.When he woke up some time later, he could not believe that he was alive. Slowly he moved his arms, then his legs. They seemed all right. He was lying in a huge pile of snow. When he looked up, he saw a large fir tree. Its branches had broken his fall and the pile of snow had completed his soft landing.When he got to his feet, he found that his back and one leg hurt but he was able to walk. He made his way to a German farm, and soon he was a prisoner, in a hospital bed. At first the Germans did not believe his story. Later , however, they found the crashed plane and his partly-burnt parachute, with his name and number on it. This was the first time a man had jumped five and a half kilometers without a parachute and still lived!46. Why did Nick take off his parachute?A. Because it was too heavy for him to carry.B. Because the rear-gun position was very small.C. Because he would feel safer without it.D. Because it was not allowed to wear a parachute in the rear-gun position.47. Why did Nick have to jump without the parachute?A. Because it could not be found.B. Because it could not be opened.C. Because it caught fire.D. Because it was stuck under the seat.48. What did Nick have to decide to do when the plane burst into flames? .A. Whether to jump without a parachute and maybe die.B. Whether to remain in the plane and maybe escape death.C. Whether to fight the fire and maybe burn to death.D. Whether to wait for the plane to make a dangerouslanding49. Nick was saved by __________.A. a German soldier.B. the soft groundC. a large fir treeD. a German farmer50. Wh y didn’t the Germans believe his story at first?A. Because he was still alive after jumping from a great height without a parachute.B. Because only one of his legs was hurt after he jumped from the plane.C. Because he was able to walk without help to a German farm.D. Because they found the crashed plane and his partly-burnt parachute.Part III Vocabulary and Structure (15%)Directions:There are 30 incomplete sentences in this part.

Some of us will prepare ourselves to serve our country in the government, or in its armed forces. Youth comes only once in a lifetime.

We are better able to learn more during this time than when we are older. Since learning is easy, the young person should try his hardest to learn as much as he or she can. The knowledge will be useful in later years. During our younger years, we have the enthusiasm and the vitality to set high goals for ourselves.

2019年职称英语：卫生类A级阅读判断精华练习题(7)阅读判断题阅读下面这篇短文，短文后列出了7个句子，请根据短文的内容对每个句子做出判断。

如果该句提供的是准确信息，请选A；如果该句的是错误信息，请选B；如果该句的信息文章中没有提及，请选C.Cosmetic SurgerySurgery that can improve the way a person looks is becoming more and more popular in the United States. Thiskind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive （有竞争力的）in their jobs. Men especially are beginning to turn to face-lifts （面部拉皮手术）, liposuction （taking fat out of the body）, and implants （putting artificial, parts into their bodies） to help them look younger. As companies downsize（缩编） and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. These operations are not without dangers, however.One young woman had an eye operation to get rid of the bags under her eyes. She described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he'd given me an injection near my eyes, I saw everything." She went on to explain, "1 knew I had to keepstill because of what he was doing. He was scraping （刮）away fat underneath my eyes. It took about ten minutes. After he finished, I felt I couldn't walk. I was so faint." Her troubles did not end after the operation for two weeks. Hereyes were swollen （肿胀的） and almost completely closed, and even dark glasses could not hide the side effects of the operation.Liposuction, taking fat out of the body, is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the place where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine like a vacuum cleaner is then used to suck the fat out of the body. However, as one doctor explained, some problems can happen after the operation. He warned; "Irregular lumps and loose skin can result from this operation. If it is not evenly done, liposuction can produce a very lumpy result." Patients often must have more liposuction to correct the problem.1 Cosmetic surgery is more popular in the US than anywhere else.A RightB WrongC Not mentioned2 The way a man looks has little to do with the job opportunities he may have.A RightB WrongC Not mentioned3 There are hardly any risks involved in cosmetic operationsA RightB WrongC Not mentioned4 The young woman was by no means satisfied with the eye operation.A RightB WrongC Not mentioned5 The eye operation was such a failure that the woman refused to pay for it.A RightB WrongC Not mentioned6 Not everyone is a good candidate for liposuction.A RightB WrongC Not mentioned7 Sometimes liposuction patients may have to undergo more than one operation.A RightB WrongC Not mentioned【参考答案】1.
