【推荐2】In the field of educational technology, some apps might be getting too smart. There are more and more apps providing help for students.

PhotoMath

The new, seemingly magic app allows users to take pictures of a math problem, and then receive a step-by-step solution. It is now the number one free app on the App Store. A PhotoMath spokeswoman says educators have welcomed the app with positive reviews, but the software causes a lot of angry public discussion and disagreement. Why? It is because students can use it to cheat when doing their math homework.

Homework Helper

Chinese Internet search company Baidu has launched (发起) an app called Homework Helper with which students can get answers to homework. Users post a picture or type their homework questions onto online forums (论坛), and those who answer the questions can win e-coins that can be used to buy devices like iPhones and laptops. The app has logged 5 million downloads, much to the concern of many parents who argue that the students spend less time thinking about challenging problems.

【推荐2】Two teenagers are lost at sea off the coast of the United States for six days on their small sailing boat. Without any food and drink, the boys drink sea water. They try slipping into the ocean to cool off, but sharks drive them back onto the boat. At night, they use a single wet suit to keep warm.

This is a real story of two American boys. Driscoll and his best friend, 18-year-old Josh Long, were found six days later and more than 100 miles from where they had set off from Sullivan’s Island, South Carolina, on April 24. The boys had lost a lot of water and were tired, but otherwise in pretty good shape.

They set out fishing on a 4.3-meter sailboat on a windy day when the National Weather Service had warned small boats to stay out of the water, but they didn’t care. They realized they were in trouble almost immediately and tried to swim back to shore, pulling the boat along with them. Within hours, they were far out to sea.

“We lost our fishing equipment, ” Driscoll said. “So we couldn’t catch any fish. ” The boys’ hopes faded with each day passing. They stood on their boat every time they saw another boat, waving and shouting, but without success. One night they were woken up by water coming into the boat. A large ship was very close to them.

A coast guard boat set out to look for them. The boys got up and made some noise. This time, they were heard.

“What we have is a completely surprising story of survival that’s going to be studied for years to come, ” said Richard Goerling, Long’s uncle, “ I think the boys have a book to write. ”

But we often buy food that’s been produced in huge amounts and that’s traveled many miles before it ends up on our plate. So for some, growing their own food is a better choice – and it tastes good too!

From growing vegetables in little pots on your balcony to taking care of a small plot of land, there are many ways to produce home-grown food. It can be backbreaking work digging, weeding and watering the soil, but the result is fresh, home-grown fruits and vegetables, helping us keep a ‘five-a-day’ diet.

The recent Covid-19 pandemic lock-down means demand for homegrown food has seen a comeback in the UK. Miriam Dobson from the University of Sheffield, told the BBC that some people have been spending a lot of their time on their plots, growing plenty of fresh fruit and vegetables – which, at times, have been challenging to buy in supermarkets. She says “Coronavirus has reminded people of the weakness within our global food system. In such a difficult time, interest in self-support rises.”

But for those with limited space, a solution to grow your own vegetables lies closer to home – using pots. Sheila Brand lives in a third-floor flat in Rotterdam. She has managed to grow tomatoes and eggplants and is already harvesting raspberries. She told the BBC watching the plants grow “is very exciting: 'Oh it's got a new leaf!' ”

As well as the benefits of saving money and enjoying tasty food, growing your own from a balcony or window ledge not only improves your well-being and immediate environment, you can actually grow a lot of vegetables. So, maybe it’s time for us all to get planting and develop our green fingers!

【推荐1】In South Korea, students pay for classes in everything from K-pop auditions (韩流试镜)to real estate (房地产)deals. Now, top Korean firms are using artificial intelligence (AI) in hiring, and job-seekers want to learn how to beat the robots.

From his basement office in Seoul, career consultant Park Seong-jung is among those in a growing business of offering lessons in handling recruitment screening by computers, not people. Video interviews using facial recognition technology to analyze character are key, according to Park.

"Don't force a smile with your lips," he told students looking for work in a recent session, one of many he said he has conducted for hundreds of people. "Smile with your eyes".

Classes in dealing with Al in hiring, are still a tiny part of the country's multi-billion-dollar cram school (补习学校)industry. But classes are growing fast, operators like Park's People & People consultancy claim, offering a three-hour package for Up to 100,000 won ($86).

There's good reason to see potential. As many: as 8 out of every 10 South Korean students are estimated to have used cram schools, and high youth unemployment in the country—nearly one in four young people are not in the workforce—offers a motivation not present in other countries where cram schools are popular, like Japan.

One AI video system reviewed by Reuters asks candidates to introduce themselves, during which it spots and counts facial expressions including "fear" and "joy" and analyses word choices. AI hiring also uses "gamification" to judge a candidate's personality and adaptability by putting them through numbers of tests. Preparing for such tests doesn't necessarily involve simply memorizing answers. Some games don't even have a 'right answer', as they are aimed to spot the problem-solving attitude of the applicant.

Consultant Park said he gave Al firing talks to more than 700 university students, graduates and lecturers in 2019. In an online chat room monitored by Park, with more than 600 participants, numerous messages indicate thanks for the classes and success in AI interview quests. "Students are struggling from the emergence of AI interviews. My goal is to help them be fully prepared for what they will be dealing with," said Park.

【推荐2】There are three different kinds of friends in our life. I classify (分类) them according to how well I know them and how well they know me.

The first type of friend is just an acquaintance (熟人). This means that you only know their names. You might not even remember what they look like if you go away for a short vacation. You don't miss them when they are elsewhere. It is also this type of friend who gives you the most amount of aggravation(恼怒). Since most of the time you are placed in a position where you have to act friendly. You would not normally tell an acquaintance when he or she is doing something that makes you feel angry, such as tapping the fingers on a table or shouting loudly. I call them "pest friends".

The second kind of friend is a "guest friend". They are just social partners. You meet them at a certain location and at the end of the meeting you go your separate way and they go theirs. You don't talk too often with this sort of friend, and you don't share each other's secrets.

Lastly, we have "best friends". This sort of friend is there when you need them. They know you as a person and they are there through thick and thin. Best friends are the ones that you can lean and depend on no matter what happens. If you need a listening ear, they will be the one to lend support.

Friends come in all different shapes and sizes. Every friend has an impact on our life.

【推荐3】Growing up in an Italian-American household was, for me, pretty special. My mother, Gina, an immigrant from Italy, held on to so many of her family's traditions that at times, regardless of the fact that I was living in American, our home felt like in Italy.

To this day, my mother only speaks to me in Italian. She may speak in some English terms and expressions from time to time, but our conversations are, for the most part, in her mother tongue. And most of those conversations are about food. For us, food —Italian food is an important part of our lives. The food my mother prepared for me and my sister as children is the same food my grandmother created in her small farm kitchen high up in the mountains.

One of my family's dishes of heritage I made sure to learn and perfect is my mother's arancini di riso (Italian rice balls). Arancini, in Italian, means little oranges. After you roll some leftover rice into a small ball, place a piece of mozzarella   (马苏里拉奶酪 )   in the center, then bread that and fry it, the golden outside resembles one of our favorite fruits. For my family, it also showcased my mother' s ability to always find a delicious way to never let anything go to waste: Last night's good rice was repurposed into this perfect mid-day snack or dinner appetizer.

So, when I take a perfect little arancini out of the hot oil and crack it open, I am immediately transported back to my childhood: I am a little girl getting off the bus and running through the back door to the smell of last night's rice transformed into sticky, delicate goodness. This small snack symbolizes so many important elements in my life: my mother' s waste-not philosophy, her ability to take a few simple ingredients and transform them, and finally, the way she carried her mother' s recipes to the U. S. in her mind and heart so she could, years later, teach me about my heritage through food.

Eating arancini, and all the other recipes my mother continued to make here in the U. S. after leaving Italy, allowed her to teach me who I am, where I come from, and why I should be proud of it all.
