1 . A teenager of 17 walks into a corner store and grabs a Coca-Cola, but the cashier refuses to sell it to him because he is underage. That rule is expected to soon become reality in parts of Mexico, as lawmakers in several states push legislation (立法)to keep junk food away from children. know it can sound a bit difficult but we have to take action now," says Lopez, a lawmaker in Oaxaca's Congress.
More than 70,000 Mexicans have died from COVID-19, the world's fourth-highest recorded death toll, tracked by Johns Hopkins University. 89% of those who died in Mexico had an underlying medical condition such as obesity, diabetes (糖尿病)，high blood pressure and heart problems. That has led to a new urgency to change diets so that the younger generation doesn't suffer those illnesses.
The critics, however, say the leaders are using preexisting health conditions in COVID-19 patients to distract from a weak government response to the virus outbreak. Yet few people would deny that the country consumes large amounts of sugar-sweetened drinks and processed snacks with little nutrition --- or that Mexico has a major weight problem.
Oaxaca's governor approved the state's junk food prohibition last week. Legislators still have to complete the legal systems, and punishment could include fines and even jail. Lopez says legislators from all over the country have called her for advice. Many other states are debating a junk food ban. However, a nationwide law would not be easy. "There are powerful commercial interests that least want it to happen, but we must prioritize the well-being of our children," Lopez says.

2 . A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.
According to course instructor William Barry associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, an achievement he described as “remarkable." The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.
Before becoming a student, Bina48 speared as a guest speaks in Barry's classes for several years. One day when addressing Barry's class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course^ Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry Therefore the challenge would be for Barry and his students to teach Bina48 what love is.
"Some interesting things happened in the class," said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is "fairly simple — it's a feeling," said Barry. But the reality was different. Bina48 ended up learning "31 different versions of love," said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.
Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with, students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bma48 and NDNU classmates were the winners of this debate.
In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely。

3 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.
I decided to think up a method of dealing with forbidden fruit.
"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."
"What's that?" they asked.
"It's a large wooden chest full of toys for my grandchildren," I replied,
"You don't have grandchildren," someone said.
"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."
My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.
The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."
I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

4 . For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.
Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.
To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.
Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.
Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.
Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.
But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.
The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.

| B．Too much workout often slows metabolic rates. |
| C．Lifestyle is not as important as morning exercise. |
| D．Physical exercise before breakfast is better for health. |
5 . Our culture is the system we use to build our identity. All living things are part of a culture. Even animals have a culture! So what is culture? It's the way we behave in a group. It begins with each individual (单个的) family. Within our families we do things to build relationships with each other. This can include routines like daily housework and weekly shopping. It also includes traditions. Traditions are activities that are repeated on a regular basis.
Culture is not limited to individual family groups. The real strength of culture is in larger community groups. These larger groups are called societies. Every society makes rules for itself. It decides how people should act in different situations. Some of these rules are written down. Some are just things that are naturally expected of all members of that society.
Often, cultures can be recognized by what the people believe. Cultures are also known by what they choose to include in their art. Sometimes cultures may be formed by people who speak the same language. Cultures may also be known for their customs, including the foods they make and the things they do.
Our cultures help us understand who we are and what we believe. There are very strong feelings connecting us to our own society. Two different cultures may disagree on something, especially if they both feel strongly about it. When that happens, war is a common result.
People are learning better ways to communicate with each other. The more we communicate, the more we appreciate the differences in cultures.

6 . When you live in total messiness—cookies in your pants draws, and some old New Yorkers or apple seeds in your bed—it's hard to know where to look for when you lose your keys. The other day, after two weeks of searching, I found my keys in the refrigerator. I can't say I was surprised. But I was surprised when I was diagnosed with ADHD（多动症）,when I was a junior at Yale.
According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.
Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me,who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.
Dr.Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.
Besides, the idea that young women actually have ADHD often causes skepticism. As a top student,I didn't believe my diagnosis at first. My friends were also confused,and rather certain my doctor was misguided.
"Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says."Girls will hide their inability to meet social expectations. They see their trouble organizing,and concentrating as character flaws（缺陷）."
These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.

7 . Whenever something looks interesting or beautiful, there is a natural desire of us to capture (捕捉) and preserve it — which means, in this day and age, that we are likely to reach for our phones to take a picture.
Though this would seem to be an ideal solution, there are two big problems associated with taking pictures. Firstly, we are likely to be so busy taking pictures that we forget to look at the world whose beauty and interest encourage us to take a photograph in the first place. And secondly, because we feel the pictures are safely stored on our phones, we never get around to looking at them, so sure are we that we’ll get around to them one day.
The first person to notice the problems was the English art critic (评论家), John Ruskin. He was a keen traveler who realized that most tourists make a poor job of noticing or remembering the beautiful things they see. He argued that humans have a natural tendency to respond to beauty and desire to have it, but there are better and worse expressions of this desire. At worse, we get into buying souvenirs or taking photographs. But, in Ruskin’s eyes, there’s just one thing we should do — attempting to draw the interesting things we see, regardless of whether we happen to have any talent for doing so.
Ruskin said, “Drawing can teach us to see: to notice properly rather than gaze absent-mindedly. In the process of recreating with our own hand what lies before our eyes, we naturally move from a position of observing beauty in a loose way to one where we acquire a deep understanding of its parts.”
Ruskin deplored the blindness and hurry of modern tourists, especially those who prided themselves on travelling around the whole Europe in a week by train, “No changing of places at a hundred miles an hour will make us stronger, happier, or wiser. There was always more in the world than men could see, if they ever walked slowly; they will see it no better for going fast. The really precious things are thoughts and sights, not pace.”

8 . More than 10 years ago，it was difficult to buy a tasty pineapple (菠萝)．The fruits that made it to the UK were green on the outside and，more often than not，hard with an unpleasant taste within.Then in 1996，the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowygold than green. It was slightly softer on the outside and had a lot of juice inside.But the most important thing about this new type of pineapple was that it was twice as sweet as the hitandmiss pineapples we had known.In no time，the Del Monte Gold took the market by storm，rapidly becoming the world’s bestselling pineapple variety，and delivering natural levels of sweetness in the mouth，up until then only found in tinned pineapple.
In nutrition (营养) it was all good news too.This nicetasting pineapple contained four times more vitamin C (维生素C) than the old green variety.Nutritionists said that it was not only full of vitamins，but also good against some diseases.People were understandably eager to be able to buy this wonderful fruit.The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a_fixture in the shopping basket of the healthy eaters.
Seeing the growing market for its winning pineapple，Del Monte tried to keep the market to itself.But other fruit companies developed similar pineapples.Del Monte turned to law for help，but failed.Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.

9 . Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
" I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene.
The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented(增强的) reality, a technology already available on smartphones and tablets (平板电脑) that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would pop up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
" As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. " We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device (装置) that's hundreds and hundreds of dollars. "
9to5Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones.
"It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. " There's gonna be improvements to that, and this a step there. "
1. One of the possible functions of the smartphone-like glasses is to _____.| A．program the opening hours of a bar |
| B．supply you with a picture of the future |
| C．provide information about your surroundings |
| D．update the maps and GPS in your smartphones |
| A．develop rapidly | B．get round quickly |
| C．appear immediately | D．go over automatically |
| A．necessary for teenagers | B．attractive to New Yorkers |
| C．available to people worldwide | D．expensive for average consumers |
| A．may have a potential market | B．are as common as smartphones |
| C．are popular among young adults | D．will be improved by a new technology |
