The company partnered with researchers at the University of Exeter in Britain and the Met Office，the British government's national weather service.The team says tests of the system showed it produced more accurate predictions，or forecasts，for short-term rainfall than other existing systems. Accurate nowcasting can be a very important tool for preparing for possible weather emergencies. It can be used by officials in the areas of water management，agriculture，air and ground traffic control and outdoor event planning.“We were especially interested in the ability of these models to make predictions on medium to heavy-rain events，which are the events that most impact people and the economy，” the team said.The scientists said their model aims to create predictive “movies” of immediate weather patterns. They said that，unlike other systems，theirs can accurately capture large-scale events，as well as several different rain possibilities. This combination permits “rainfall uncertainties” to be deeply explored. During the testing process，the team said the model showed “statistically significant” improvements in these areas compared to competing methods. In addition，the researchers reported that a group of more than 50 weather experts from the Met Office rated the AI model to be more accurate and useful in 89 percent of cases than existing forecasting systems. 　　Despite the study results，researchers admitted that the model still has limitations. They said “more work is needed to improve the accuracy of long-term predictions and the accuracy on rare and intense events.” The team said it will now center on developing new methods to test and measure the model's performance. It will also work to create more specialized systems to work in real-world conditions. 语篇解读　本文是一篇说明文。文章主要介绍了英国研究人员创建了一种人工智能模型，可以高效预测未来90分钟内的降雨。 1. What do we know about the new AI model? A．The model is created by researchers of Met Office. B．The model can predict any rainfall within 90 minutes. C．The model needs improving in long-term forecasting.

A．The difficulty of accurate nowcasting. B．The relationship between weather forecasting and economy. C．The necessity of building the new AI model. D．The principles of the new model. 段落大意题。通读第三段及第一句“Accurate nowcasting can be a very important tool for preparing for possible weather emergencies.”可知，本段主要讲述了构建新的人工智能模型的必要性，故选C。 √ 3. Why does the writer mention the weather experts from the Met Office in Paragraph 4? A．To prove the advantage of the new model. B．To compare the new model with the old systems. C．To explain the rule of weather forecasting. D．To show how the existing system works. 写作手法题。根据第四段中“In addition，the researchers reported ...than existing forecasting systems.”可知，作者提到了来自英国气象局的气象专家是为了证明新模式的优势，故选A。 √ 4. Which of the following can be the best title for the passage? A．Existing Forecasting system Needs Improving B．AI Predicts Immediate Rainfall Better than Existing Systems C．New Explorations in Weather Predictions D．New Methods on Testing the AI Model's Performance 标题归纳题。通读全文及第二段“The team says tests of the system showed it produced more accurate predictions，or forecasts，for short-term rainfall than other existing systems.”可知，本文的最佳标题为AI Predicts Immediate Rainfall Better than Existing Systems，故选B。 √ B Growing up，we are constantly reminded that young people are heavily affected by technology. We are the “antisocial club”，those who prefer to text our friends in the same room rather than make eye contact with them. And even though never-ending studies reveal to us the extent of our social media addiction，we should at least consider that it's not only our young people's problem any more. There's the rise of the Instagram mums，who like to post an abundance of cute baby pictures，share their mom feelings along the way and show their wonderful lifestyles. They are the so-called “Facebook mum generation”，a growing group of parents that like to overshare. While all of this might be fine，and even a little humorous，new research suggests that parents' technology addiction is negatively affecting their children's behavior. According to the study，40% of mothers and 32% of fathers have admitted having some sort of phone addiction. This has led to a significant fall in verbal interactions within families and even a decline in mothers' encouraging their children. 　　There is no denying that I get annoyed when receiving the words “I'll be with you soon” from a parent，when all I want to do is ask one question. But，at the same time，every day leaving the room to wait until my father is finished with his “serious business” (Farmville)，has now become the norm. Whether you want to escape your disturbing children for a bit，or want to stay up late flicking through Twitter，know that wanting to do all of these is normal. We，your children，know how addictive it can be and how difficult it is to switch off.But before telling us to put our phones away at the table or even worse，listing statistics of how damaging social media can be for us，maybe lead by example，considering how much time you spend on the phone and how this is impacting your children and your relationship with us. Maybe in this way we can work on our addiction together. 语篇解读　本文是一篇议论文。文章主要讨论如今青少年有严重沉迷手机的现象，但新的研究表明，父母对科技产品的沉迷会对孩子的行为产生负面影响。 5．What can we know from the first paragraph? A．Teenagers nowadays enjoy socializing with their friends. B．Teenagers nowadays send messages to their friends every day. C．Teenagers nowadays hate to make eye contact with their friends. D．Teenagers nowadays are heavily addicted to their mobile phones. 细节理解题。根据第一段可知，如今的青少年严重沉迷于他们的手机。故选D。 √ 6．What does the author think of mums' oversharing? A．Boring.　　　　 B．Selfish. C．Funny. D．Meaningful. 观点态度题。根据第二段“There's the rise of the Instagram mums，a growing group of parents that like to overshare.”以及第三段“While all of this might be fine，and even a little humorous”可知，作者认为妈妈们的过度分享是滑稽可笑的，其中humorous是关键词，故选C。 √ 7．The underlined word “norm” in Paragraph 4 probably means________． A．security B．standard C．routine D．custom 词义猜测题。根据画线词后文“Whether you want to escape ...know that wanting to do all of these is normal.”可知，每天离开房间等待父亲做完 “正经事”(Farmville)，现在已经成了一种常态。故画线词意思是“惯例，常规”。故选C。 √ 8．What's the main purpose of the article? A．To share the author's own experience with the readers. B．To call on parents to get rid of their own media addiction. C．To reveal that parents are always addicted to mobile phones. D．To show the author's dissatisfaction with parents' phone use. 写作目的题。根据最后一段中“But before telling us to put our phones away ...Maybe in this way we can work on our addiction together.”可知，这篇文章的目的是呼吁家长们摆脱对媒体的沉迷。故选B。 √ C 　　Most of the 20th century has been a development on the Industrial Revolution taken to an extreme(极端): people now own more products than ever before; there are enough nuclear weapons to destroy the earth several times over; there is hardly any forest left and pollution has got to the point where we buy water. Within a few years I predict you will be able to buy air—there once was a time when you didn't need to buy food or shelter either. Important developments in the last century are the breaking down of the class structures left over from the Industrial Revolution stage，bringing with it the empowerment(授权)of the “common man”： the working day is set by law to only 8 hours a day; everyone has the vote; the media has less obvious government control; people have landed on the moon，sent spacecraft to Mars and so on. Families have also been shrinking ; the nuclear family came about，and especially in the last half of the 20th century，one-parent families are becoming more common. The smaller size of the family shows the increased independence of people—once upon a time people had to live in large groups to survive. Humans have realized their personality and independence and taken their control of the world to an extreme.In many countries the land is almost completely used in the production of food and as living space.People live in small cities which are entirely human constructed ，made from materials which are also entirely human constructed(concrete bricks)with hardly any remains of nature. Weeds are poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short and soon. I think the massive drug “problem” troubling people is a result of too much of this influence，humans needing to escape the dull world they have created by entering fantasy worlds. Over the last 100 years，the 20th century consciousness has spread throughout the world.Most of Asia has been thoroughly “Westernized”，and most of the Third World is being over-run by Western ways of doing things and living. 语篇解读　本文是一篇说明文。文章主要介绍了工业革命给20世纪人类社会带来的改变。 9. How is the text mainly developed? A．By giving examples and stating facts. B．By stating facts and making comparisons. C．By listing facts and arguing. D．By predicting and concluding. 写作手法题。通读全文，尤其是第一段的“Most of the 20th century has been a development...pollution has got to the point where we buy water.”可推断出，文章主要是通过陈述事实和进行比较来开展的，故选B。 √ 10. What does the underlined word “shrinking” in Paragraph 2 mean? A．Becoming smaller. B．Getting better off. C．Disappearing sharply. D．Becoming popular. 词义猜测题。根据第二段的“the nuclear family came about，and especially in the last half of the 20th century，one-parent families are becoming more common”可知家庭在萎缩，因此画线词shrinking的意思是“缩小”，即Becoming smaller，故选A。 √ 11. Which of the following situations is NOT mentioned in the text? A．Effects of pollution. B．Changes in people's way of living. C．Development in science and technology. D．Control of population. √ 细节理解题。根据第一段的“there is hardly any forest left and pollution has got to the point where we buy water. Within a few years I predict you will be able to buy air”可知，此处提到了污染的影响；根据第二段的“The smaller size of the family shows the increased independence of people—once upon a time people had to live in large groups to survive.”可知，此处提到了人们生活方式的改变；根据第二段的“people have landed on the moon，sent spacecraft to Mars and so on.”可知，此处提到了科技的发展，因此D选项没有被提到，故选D。 12. What can we infer from Paragraph 2? A．Birth rate is over controlled. B．Population quality has greatly improved. C．People have more rights and freedom. D．Government has lost control of society. 推理判断题。根据第二段的“the working day is set by law to only 8 hours a day; everyone has the vote; the media has less obvious government control”可推断出人们有更多的权利和自由。故选C。 √ Ⅱ.阅读七选五(每小题2.5分，共12.5分) Children may not be putting coins into piggy banks for much longer. With the move towards a cashless society，pocket money is moving digital. To reflect this trend，a number of mobile budgeting apps for children has sprung up worldwide. 1 Parents can add money to children's accounts，set limits and monitor transactions，while children can choose to save their money or spend it using a prepaid card.The companies behind the apps argue that in an increasingly cashless society，they can be a valuable way of teaching young children about money. 2 These apps aim to overcome this，claiming to teach children financial concepts，such as budgeting，interest rates and income.For instance，the Swedish app Gimi has virtual savings jars where children can deposit money; parents can pay children interest as they save.Philip Haglund，CEO of Gimi believes the app has certain advantages like teaching responsible real-life spending habits，while schools tend to focus more on economic theory. “You don't become better at money management just because you have a degree in economics. 3 ” he says. One concern is that introducing digital money apps to young children could help to encourage irresponsible spending habits. “What if children don't have a good foundation in financial capability? 4 They won't learn about the real value of money and might develop bad money habits. ” says an expert. However, Haglund says it is important for kids to learn and make mistakes，“We want to help kids and teenagers gain financial skills for life. 5 If you're going to make a mistake of ￡10 at eight，it's better than making a mistake of ￡1，000 when you're 28，”he says. A．The earlier，the better. B．They offer a simple money management service for children. C．There's a risk that money apps could be seen as just another game. D．The growth of digital banking has affected how parents give pocket money. E．Now money is being transferred through cyberspace，which is really abstract. F．It's more about the attitude and the relationship you have with parents money. G．30% teenagers are unable to make simple financial decisions，according to a global survey. 语篇解读　本文是一篇议论文。文章主要就给孩子零花钱开始变得“移动化”提出了不同的观点。 　　Children may not be putting coins into piggy banks for much longer.
