It’s believed that taking air into your mouth (24) ______ enhance the flavor of the noodles, and that it helps cool down the noodles. It’s also considered to be a way to show appreciation for the dish. Sometimes, just making the noise alone seems to make the noodles more enjoyable.It wasn’t until a new expression –“noodle harassment(骚扰)”-- came out last year on social media (25) ______ Japanese people started to realize that the slurping noise is making some foreign visitors uncomfortable.(26) ______ a response, Japanese instant noodle maker Nissin introduced a so-called noise-canceling fork last month. The fork, which looks like an electric toothbrush, is connected wirelessly to a smart phone.

It was developed by researchers from both Harvard Medical School and the University of Sydney, led by Nasim Annabi, an assistant professor of chemical __31__. The glue is made from a modified (改良的)human protein that responds to UV light, allowing the application and drying of the gel-like substance in just a minute.According to the international team of researchers behind the glue,it could quite literally be a lifesaver, sealing up wounds in 60 seconds without stopping the natural __32__ and relaxing of the organ or the skin it’s applied to. Wounds __33__ with MeTro can heal up in half the time compared with stitches or staples, the researchers claim, and if surgeryis required then MeTro can simplify that __34__ too. It's also one of several ways researchers are exploring to engineer our body's own natural substances to help repair it when needed.The __35__ applications are powerful – from treating serious __36__ wounds at emergency sites such as following car accidents and in war zones, as well as improving hospital surgeries.MeTro is simple to apply, can be easily stored, and works closely with natural __37__ to heal a wound. What’s more, it degrades without leaving any kind of poisonous leftovers in the body.For now the trials are __38__ to animal models. But human trials are in the works, and the results to date are incredibly __39__. If the MeTro can be further developed into a __40__ product, it could become an essential part of a first responder’s toolkit.III.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A Swedish power plant is taking reuse and recycle to the next level by burning unusable clothing instead of coal, Bloomberg reports.Retail giant Hennes & Mauritz, more commonly known as H&M, is helping the utility transition away from coal through its moldy (发霉的) or otherwise unsalable clothing.The multi-fuel power and heating station in Västerås, central Sweden, is planning to be completely fossil-fuel free by 2020. It’s thelargest station of its kind and Sweden claims it’s one of Europe’s cleanest. To kick its coal habit, the station is turning instead to other burnable materials including recycled wood, rubbish and yes, clothes.“Our goal is to use only renewable and recycled fuels,” Jens Neren, head of fuel supplies at the utility company which owns and operates the Västerås plant, told Bloomberg.Johanna Dahl, head of communications for H&M in Sweden, told Bloomberg that the company allows only the burning of clothes which are no longer safe to use.“It is our legal obligation to make sure that clothes that contain mold or do not meet the requirements of our strict restriction on chemicals are destroyed,” she said.The Västerås plant has burned around 15 tons of old H&M clothes so far this year, compared with about 400,000 tons of rubbish, Neren told Bloomberg.Sweden has one of the world’s greener energy generating systems, and has invested in bioenergy, solar power and electric buses. In 2015, the Scandinavian country announced an ambitious aim to become one of the first nations in the world to end its dependence on fossil fuels. According to the Swedish government, the country has already heavily reduced its dependence on oil, which accounted for 75% of the energy supply in 1970, and now makes up a 20% share.56. Which of the following can serve as fuel in the Västerås plant?A. Fashionable coats in H&M chain store.B. Old TV sets deserted as rubbish.C. Wooden furniture in second-hand shop.D. H&M clothes unsuitable for sale.57. The underlined word in the last paragraph “generating” is closestin meaning to ______.A. eliminatingB. adjustingC. producingD. circulating58. What can we learn from the passage?A. The Swedish government discourages the development of bioenergy.B. Clothes only take up a small proportion of the burning material.C. Sweden’s fossil-fuel free plan is almost accomplished by now.D. Sweden has an ambition to be the cleanest country in the world.59. What is the main idea of the passage?A. A Swedish power plant is burning unusable H&M clothes for fuel.B. The Swedish government aims high and is taking effective action.C. H&M is looking for a new way to strengthen its position in fashion.D. Coal and oil are no longer regarded as the primary fuels in Sweden.(B)60. Before an adventure, a trekker should ______.A. tell the park officials his destination and time scheduleB. pack up some jungle fruit juice and pre-cooked mealsC. consult a local guide about the most adventurous routeD. have his fitness level assessed at the tourist center61. Which of the following is NOT suitable for a rainforest trekking?A. Long-sleeved cotton shirts.B. Tight sports shorts.C. Hiking boots.D. A wide brimmed hat.62. If a trekker starts out at dawn, he may ______.A. escape being caught in the rainB. sight scared wildlifeC. enjoy the heat of the tropical sunD. see animals seeking food(C)The largest genetic study of mosquitoes has found their ability to resist insecticides is evolving rapidly and spreading across Africa, putting millions of people at higher risk of contracting malaria(疟疾).British scientists who led the work said mosquitoes' growing resistance to control tools such as insecticide-treated bed nets and insecticide spraying, which have helped cut malaria cases since 2000, now threatens “to disturb malaria control” in Africa.“Our study highlights the severe challenges facing public efforts to control mosquitoes and to manage and limit insecticide resistance,” said Martin Donnelly of the Liverpool School of Tropical Medicine, who worked on the study with a team from Britain’s Wellcome Trust Sanger Institute.Latest World Health Organization (WHO) data show that 216 million people were infected last year with the malaria parasite(寄生虫), which is transmitted by blood-sucking Anopheles mosquitoes.The disease killed 445,000 people in 2016, and the majority of them were children in sub-Saharan Africa.To understand how mosquitoes are evolving, the researchers sequenced the DNA of 765 wild Anopheles mosquitoes taken from 15 locations across eight African countries. Their work, published in the journal Nature on Wednesday, created the largest data resource on natural genetic variation for any species of insect.Analyzing the data, the scientists found that the Anopheles gambiae mosquitoes(冈比亚疟蚊)were extremely genetically diverse (多样化的)compared with most other animal species. This high genetic diversity enables rapid evolution, they said, and helps to explain how mosquitoes develop insecticide resistance so quickly.The data also showed the rapid evolution of insecticide resistance appeared to be due to many previously unknown genetic variants(变体)within certain genes. The scientists said these genetic variants for insecticide resistance were not only emerging independently in different parts of Africa, but were also being spread across the continent by mosquito migration.Michael Chew, an expert at Britain’s Wellcome Trust global health charity which helped fund the research, said the finds underlined the importance of pushing scientific research ahead to control malaria.Global efforts to control malaria through effective vaccine, insecticides and the best drug combinations require urgent, united action by scientists, drug companies, governments and the WHO.63. Which of the following is scientists’ headache?A. The number of mosquitoes in Africa is growing rapidly.B. Some genetic variants of mosquitoes are still unknown.C. The existing insecticides aren’t as effective as they used to be.D. Millions of African people have resistance to medicines for malaria.64. Malaria cases can be cut by ______.A. threatening drug companiesB. spraying insecticidesC. limiting blood donationD. transmitting data65. What CANNOT be concluded from the passage?A. Children are more likely to be bit by mosquitoes.B. Many previously unknown variants are found in the study.C. The mosquito migration contributes to the spread of variants.D. Anopheles mosquitoes have great genetic diversity.66. Which is FALSE about the genetic study of mosquitoes?A. It created the largest data on natural genetic variation for any insect species.B. It found the possible causes for the rapid evolution of insecticide resistance.C. It discovered where the genetic variants emerged and how they were spread.D. It highlighted the public efforts and appealed to limit the use of insecticides.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.Imagine you're standing in line to buy an afterschool snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code with your smartphone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.__________67__________ As technology companies move away from traditional password, biometric(生物识别) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one’s fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since last year, Samsung has featured eye-scanning technology in its top smartphones, while Apple’s new iPhone X can even scan a user’s face.__________68__________ “Biometrics, ideally, are good,”John Michener, a biometric expert, told tech website Inverse. “In practice, not so much.”When introducing the new iPhone’s Face ID feature at Apple’s Keynote Event in September, Phil Schiller, Apple’s senior vice president, said, “__________69__________”But it’s already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they aren’t even twins.“We may expect too much from biometrics,” Anil Jain, a computer science professor at Michigan State University, told CBS news. “No security systems are perfect.”Earlier this year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smartphone for police.“It’s good to see biometrics being used more,” Jain told CBS News, “because it adds another factor for security. __________70__________”IV. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.It’s a common sight to see food delivery workers riding electric bikes through big cities in China. Most of them seem to be in a hurry, as they run red lights to deliver their meals in time. However, such reckless (鲁莽的)behavior often causes serious problems.In the first half of this year, food delivery drivers had 76 traffic accidents in Shanghai alone, according to the Shanghai Public Security Bureau. This means that on average, there is a food delivery worker that gets hurt or even dies on the road in Shanghai every 2.5 days.Other cities also share similar problems. In Nanjing, three people died and 2,473 were injured in road accidents related to food delivery workers in the same period, according to the Ministry of Public Security.The rise of reckless behavior among food delivery workers is closely related to the growing demand for their service, reported People’s Daily. About 150 million people in China use food delivery services, according to China Radio International (CRI). Such a big market has led to a large demand for food delivery workers, with some companies offering high salaries to attract new workers.However, food delivery workers are often under high pressure from their employers. They face company fines of 20 yuan for delivering food late and upwards of 200 yuan for receiving complaints, reported CRI. Moreover, the more orders they take, the more commission(佣金)they can earn, leading to some workers checking their mobile phones for new orders while they're riding their bikes.While most companies have measures requiring delivery workers to follow traffic rules, “there remains a problem of whether these requirements and rules for delivery workers are truly entering their ears, brains and hearts,” Wang Liang, deputy head of the Traffic Police Security Bureau, told news website The Paper.To solve the problem, some cities have taken action. Shanghai has asked companies to train their workers on traffic rules and safety. Now in Shenzhen, if a delivery worker gets caught breaking traffic rules more than twice, he or she will be banned from driving food delivery vehicles for a whole year.第II卷(共40分)I.

进入19世纪以后,科学技术水准不断提高,显微镜制造更加精良,促进生物学全面的发展,并且对积累起来的事实数据做出理论的概括,在细胞学、古生物学、比较解剖学、比较胚胎学等方面都取得新的进展。
(2) 19世纪30年代,德国植物学家施莱登和动物学家施旺提出了细胞学说,指出细胞是一切动植物结构的基本单位,为研究生物的结构、生理、生殖和发育等奠定了基础。
(3)1859,英国生物学家达尔文出版了《物种起源》一书,科学的阐述了以自然选择学说为中心的生物进化的了理论,这是人类对生物界认识的伟大成就,给神创论和物种不变论以沉重的打击,在推动现代生物科学的发展方面起了巨大作用。
(4)纵观20世纪以前的生物科学发展可以看出,在这一漫长的历史岁月中,生物课科学的研究是以描述为主的,因而可以称为描述性生物学阶段。
考点:本题主要考查细胞的发现、细胞学说的建立、内容和发展相关知识,意在考查考生能理解所学知识的要点,把握知识间的内在联系的能力。
