1 . If you're feeling hungry, what’s the easiest way to satisfy your Hunger? Many of Us will reach for a takeaway menu and order some delicious-but possibly unhealthy -food. And our increasingly hectic lives add to our need to buy ready-made food because we always have no time or energy to cook on our own.
Eating options are endless, and new technology means we can feed our desire at the push of a button. Takeaway delivery apps make ordering food quick and convenient. It's estimated that in the UK alone, people eat three million takeaway meals a day, and the three biggest delivery apps together offer a choice of 100 foods from 60,000 restaurants. Amelia Brophy, head of UK Data Products at YouGov, told the BBC that its research suggests that the frequency of takeaways ordered is expected to increase in the future.
It’s no wonder we are tempted to skip the grocery shopping, bypass the kitchen, and tuck into something that someone else has prepared. But ordering a pizza, a spicy curry or a box of noodles, can come at a price both financially and to our health. Eating too much processed and unhealthy fast food has some effect on obesity and the risk of developing certain diseases. A few years ago, the BBC Good Food Nation Survey found most people eating fast food on average two days per week gradually putting on weight.
Of course, reducing salt, sugar and fat is one way to make takeaway food healthier, as well as offering smaller portion sizes. But the best advice for you is to find a recipe book and try making your own nutritious meals. And if you haven't got time, try ordering a healthier alternative from the menu.

2 . It would be easy to believe that Mother’s Day was created by a greeting card company. After all, the day is celebrated with special sales and brunches, lots of presents and massive advertising campaigns. But the day was actually conceived more than a century ago by Anna Jarvis of West Virginia as a way of honoring the sacrifices mothers made for their children.
Jarvis’s mother, Ann Reeves Jarvis, helped start “Mothers’ Day Work Clubs,” teaching women how to care for their children. During the Civil War, she organized “Mothers’ Friendship Day,” where mothers of Union and Confederate soldiers met to try to promote harmony. The younger Jarvis Was inspired by all the things her mother had accomplished with her social work.
When Jarvis was young, she overheard her mother praying, “I hope and pray that someone, sometime, will find a memorial mother’s day honoring her for the matchless service she offers to humanity in every field of life.” When her mom died in 1905, Jarvis looked through all the sympathy cards she received. She underlined all the kind words that praised her mother, reading them over and over. The outpouring of kindness for her mother inspired her to create a day to honor all mothers.
The white carnation was her mother’s favorite flower, so it became the symbol for the day. She said it symbolized the truth, purity and charity of a mother’s love. Her idea of celebrating Mother’s Day was wearing a carnation while visiting your mother or maybe going to church together. Children were also encouraged to write letters to their mothers, sharing the depths of their appreciation.
The first official Mother’s Day events were held on May 10. 1908, at the church where her mother taught Sunday School in Grafton, West Virginia, and at the Wanamaker’s department store auditorium（礼堂）in Philadelphia. Jarvis didn’t attend the event in Grafton, but she sent 500 white carnations.

3 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.
The GSMA said that China's three major mobile operators--China Unicom, China Mobile, and China Telecom--are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the most distinguishing actors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1. What will 5G bring?| A．A completely new pattern for daily life. |
| B．Realizing the potential in many new services. |
| C．Excellent networks and national safety. |
| D．Amazing speeds for public transportation. |
| A．It may be lack of government support. |
| B．It will move forward slowly. |
| C．It will develop rapidly. |
| D．It may fall behind Europe. |
| A．set up | B．bring up | C．turn up | D．pick up |
| A．Chinese cannot own 5G in 2025. |
| B．More than half Koreans use 5G in 2025. |
| C．Only five countries will have 5G in 2025. |
| D．Europe will pay little attention to 5G in 2025. |
4 . A new study shows that the increased heat from Arctic (北极的)rivers is making sea ice in the Arctic Ocean gradually disappear. The study published this week in Science Advance was led by the Japan Agency for Marine-Earth Science and Technology, together with other scientists in the United States, United Arab Emi rates , Finland and Canada.
According to the research, the main Arctic rivers bring more heat to the Arctic Ocean than they did in 1980. River heat is one of the reasons that cause sea ice loss of the Arctic Ocean. That loss is equal to about 120,000 square miles of 1-mcter thick ice. "If Alaska were covered by 1-meter thick icc. 20% of Alaska would be gone," explained Igor Polyakov, a re- searcher at the University of Alaska Fairbanks' International Arctic Research Center.
Rivers have the greatest influence during spring. The wanning water pours into the ice covered Arctic Ocean and spreads below the ice， slowly destroying it. Once the sea ice melts(融化), the warm water makes the temperature go up. The research found that much more river heat energy entered the air. Since air is mobile, this means river heat can influence areas of the Arctic far from river deltas (三角洲).
The influence was the most prominent in the Siberian Arctic, where several large rivers go into the Arctic Ocean. Canada's Mackenzie River is the only river large enough to contribute to sea ice meh near Alaska, but the state's smaller rivers are also a source of heat.
Polyakov says that rising global air temperatures will continue to warm Arctic rivers in the future. As rivers heat up, more warm water will flow into the Arctic Ocean, melting more sea ice,
1. What does the increased heat from Arctic rivers cause?| A．Dry weather in the Arctic. |
| B．A strange disease in the Arctic. |

5 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security(安全) to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 10.42 Mbps. But by comparison, 5G promises gigabit(千兆) speeds.
“5G is one of those signs, along with artificial intelligence(人工智能)，of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle(车辆) is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have a large number of data coming from the vehicle itself, and a variety of sensors(传感器) are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane(车道). It could be weather information, but also connected infrastructure (基础设施)construction. There is lots of data behind that task, which is why we need high speeds.
Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting(打赌) that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable(显著的) because companies such as Apple are reportedly developing AR glasses to assist--or perhaps even replace--smartphones.
Ericsson stated at February' s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components(部件), the glasses could rely on hardware for processing(处理)power.
But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction, so 5G isn’t concentrated(集中) only in big cities.
1. What does the author want to stress in Paragraph 1?| A．The lightning- fast speeds of 5G. | B．The expectation of 5G world. |
| C．The difference between 4G and 5G. | D．The internet-connected devices in our life. |
| A．Exhibition. | B．Success. | C．Symbol. | D．Explanation. |
| A．How to fully expand 5G coverage(覆盖范围). | B．Smart glasses will become faster and lighter. |
| C．Why 5G isn't concentrated in big cities. | D．The importance of infrastructure construction. |
| A．A science fiction. | B．A science magazine. |

6 . Returning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.
The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.
There are three books I reread annually .The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler time. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.
While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them. The best books are the ones that open further as time passes. But remember, it’s you that has to grow and read and reread in order to better understand your friends.
1. Why does the author like rereading?| A．It evaluates the writer-reader relationship. |
| B．It’s a window to a whole new world. |
| C．It’s a substitute for drinking with a friend. |
| D．It extends the understanding of oneself. |
| A．It’s a brief account of a trip. |
| B．It’s about Hemingway’s life as a young man. |
| C．It’s a record of a historic event. |
| D．It’s about Hemingway’s friends in Paris. |
| A．Debt |

7 . This morning we're going to head off down into the wetland, into a very specific kind of wetland called the Prairie fen.
You can find Nate Fuller counting butterflies. The Sarett Nature Center needs an accurate count of Mitchell's satyr butterflies to help preserve one of their last known habitats. They're very particular about the kind of habitat where they can live, which is part of what makes them so rare and amazing indicators for our water quality. Today, Sarett expert Ashley Cole-Wick with Michigan's Natural Features Inventory helps Fuller count. She says "When I first started working on the butterfly in 2013, we had 18 populations and this year in 2019, we have 10."
The Mitchell Seder went on the endangered species list in 1991. Initially it was thought that loss of wetlands contributed to their decline. Fuller says "It's not just habitat availability. Its groundwater and the amount in the quality of groundwater coming into these wetlands seem to be a challenge for the butterfly. Nothing has all been sorted out exactly. ” While the decline is likely a combination of factors. the fact that water quality might contribute is alarming because the wetlands are the headwaters for the Midwest's rivers and streams.
A captive breeding （人工繁殖）program was started four years ago at the Toledo Zoo to help get to the bottom of the mystery. Today Director Ryan Walsh who heads the program says it's been, the only successful captive program. The caterpillars （毛毛虫）spend the winter in a special weather control room that help determine the Mitchell satyrs don't do well below 4. 4 degrees Celsius, a temperature that prevents the Fen wetlands from the hard freezes which kill the insects. With that knowledge, the program produced 1300 new eggs this summer, a development that may go a long way toward restoring the population. And if all goes well, may one day the Mitchell satyr butterfly earn a ticket off Endangered Species List.

8 . When you don’t have a car and need to get around, are you more likely to call for an Uber or Lyft, or a cab? Last Friday, Lyft — the ride-sharing company, went public as its stocks (股票) started trading on the market. Lyft has become the first big initial public offering of the “gig economy” age. While the company is not making profits yet, it is changing the meaning of work. What is gig economy and what makes it so appealing?
Gig works are independent contracts (合同) or part-time jobs such as Uber. In the gig economy, companies hire independent contractors instead of full-time employees. This is different from traditional companies where full-time workers hold a lifetime career. In the past, only small companies hired contractors, while today, employers like Amazon and Google rely on temporary workforce. These companies save costs as they are not legally required to provide healthcare benefits, retirement savings or paid time off to gig workers.
Gig work appeals to different people for different reasons. For some, it affords flexible timings and for otliers who are looking for full-time jobs, it provides a source of income to support themselves. Some people work a full-time job and supplement (补充) their salary with gig jobs such as driving for Uber or Lyft.
Joining the gig economy may be simple, but maintaining a steady career is easier said than done. Gig work comes with unsteady pay and workloads. You're your own boss. It sounds fun, but when you have no self-control and an unsteady job, you might splurge all your money the first week and live on bread pieces for the rest of the month! Besides a strong sense of responsibility, gig workers have to stay up to date to get companies to hire them.
Despite the challenges gig workers face, nearly 60 million Americans are part of this workforce. As this number grows, we have to see how society and companies adapt to this new world of work!

9 . According to a new study， teens focus on rewards and have a hard time learning to avoid punishment or consider the consequences of alternative actions.
University College London researchers compared how teens and adults learn to make choices based on the available information. They tracked the way in which 18 volunteers aged 12-17 and 20 volunteers aged 18-32 completed tasks in which they had to choose between abstract symbols.
Each symbol was consistently associated with a fixed chance of a reward, punishment, or no outcome. As the trial progressed ， participants learned which symbols were likely to lead to each outcome and adjusted their choices accordingly. Teens and adults were equally good at learning to choose symbols associated with reward， but teens were less good at avoiding symbols associated with punishment. Adults also performed significantly better when they were told what would have happened if they had chosen the other symbol after each choice， while teens did not appear to take this information into account.
“From this experimental lab study we can draw conclusions about learning during the teen years. We find that teens and adults learn in different ways， something that might be relevant to education," said lead author Dr. Stefano Palminteri. " Unlike adults, teens are not so good at learning to adjust their choices to avoid punishment. This suggests that incentive systems based on reward rather than punishment may be more effective for this age group. Additionally, we found that teens did not learn from being shown what would have happened if they made alternative choices."
To interpret the results, the researchers developed computational models of learning and ran simulations （模拟）applying them to the results of the study. The first was a simple model, one that learned from rewards, and the second model added to this by also learning from the option that was not chosen. The third model was the most complete and took the full context into account, with equal weight given to punishment avoidance and reward seeking. For example, obtaining no outcome rather than losing a point is weighted equally to gaining a point rather than having no outcome.
Comparing the experimental data to the models, the team found that teens" behavior followed the simple reward-based model while adults" behavior matched the complete, contextual model. “Our study suggests that teens are more receptive to rewards than they are to punishments of equal value, ” said senior author Dr. Sarah-Jayne Blakemore. “As a result, it may be useful for parents and teachers to frame things in more positive terms.”

10 . Kevin, diagnosed with Dyslexia(读写困难症), rarely spoke a word in class, and if he did, it would be a “ Yes,” “No,” or “Maybe,” in response to questions. He always scored badly in tests and saw no hope for the future. That was until he met Sarah, an advisor at a youth centre Kidpreneur.
In 2012, Kevin attended a course called Ready Set Go in that centre. The course was for disadvantaged kids in Kingswood – a low – income area in Sydney’s western suburbs – and its goal was to teach the kids how to create businesses and offer value to the neighborhood.
At the end of the course, Sarah took the kids to the local area. She asked volunteers to share their business experiences – Kevin immediately put up his hand. His challenge was to trade his hot – dog selling service for free bread at a bakery. Although scared, Kevin was able to share his entrepreneur(创业) story with the shop owner and asked if he could exchange his service for some bread. Unexpectedly, the shop owner told Kevin how moved he was by his story and handed him some bread for free. By the end of the afternoon, his belief in himself and what was possible was at an all- time high.
The following week, Kevin sold 70 hot – dogs in two hours and made over $200. Soon after, he delivered public speeches in 20 schools, and was selected as part of his school’s leadership team. Now he heads a business group working on how to increase potential customer base.
All of his would not have been possible if Kevin had not found his passion and perseverance to improve himself, and those around him. The guidance and trust of his advisor also helped to kindle his enthusiasm to go after his goals and dreams in life.
