【推荐3】Not all great meals come from restaurants. Some are served from carts and stalls, and eaten on the go. So-called street food is not only delicious, but can be found in nearly every country, rich or poor, says Carla Diamanti, co-author of Street Food: Authentic Snacks from Around the World.. “It’s a way to get to know the people and the flavor of a place ,”says the Italian writer, who has nibbled(细咬) her way around the globe. She shares some favorite snacks----and snacking places with us.

Naples, Italy

Pizza: Pizza may be the closest thing to a global food, but Diamani says there’s nothing like the way it’s prepared in Naples. The dish is often ordered from a window counter and quickly baked for customers. If you’re eating it on the go, you fold it up for pizza al portafoglio（钱包）, literally wallet style. “Our pizza is quick and simple,” she says .www. inaples. it

New York

Hot dogs: When foreigners first visit America, one of the first things many want to try is the country’s typical snack food, the hot dog. “It’s like the flag of America---both inexpensive and democratic,” Diamanti says, “You expect to see kids queuing at a hot dog stall.” 212--484--1 200; www.nycgo.com

Japan

Bento boxes: Diamanti says the best time and place to eat this portable Japanese meal is under a blooming cherry tree in the spring. Bento boxes are filled with different dishes: often fish, meat, pickled vegetables, rice or tofu. “It’s really just a taste,” she says. While the containers are often elaborate（精心制作的） wooden serving trays, they can be also cardboard boxes ordered to go.212--757--5 640;www.jnto.go.jp

Jamama el Fna Square ,Marrakech, Morocco

Food stalls: When the sun begins to set, this central square comes to life as crowds gather to sing, dance and eat. Hundreds of stalls serves grilled meat, chicken and rice “There is plenty of smoke with hundreds of people cooking at the same time,” Diamanti says. 212—221—1 583;www.visitmorocco.com/index.php/eng/

【推荐1】Could the device, smartphone or PC, which you are using affect the moral (道德的) decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.

One case of the questions participants were asked is the classic “trolley (有轨电车) problem”: A runaway trolley is headed towards five people tied up on a set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33.5 percent of smartphone users chose, compared to 22.3 percent of PC users.

“What we round in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma,” Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”

As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily. “It’s clear that we need more research on how our devices affect our moral decision-making because we’re using screens at an ever increasing rate.”

【推荐2】Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area had a rainforest in the past.

The researchers collected a piece of Earth sediment (沉淀物) from under the seafloor off the coast of Antarctica. In the sediment they discovered forest material that was estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals. The sediment was removed by scientists on the research icebreaker RV Polarstern in the Amundsen Sea near Pine Island Glacier.

Johann Klages is a geologist with the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research in Germany. He was the lead writer of a study on the findings, published in the journal Nature. He said the sediment was collected from a depth of about 30 meters below the ocean floor. Klages said an examination showed that the material didn’t form in the ocean.

The researchers estimate that the area—about 900 kilometers from the South Pole—had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 and 25 degrees Celsius. The soil included fine dirt particles (颗粒) and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Klages added that the plants included trees, ferns and flowering plants. While no animal remains were found, Klages said there were likely dinosaurs, flying reptiles (爬行动物) and many insects in the environment.

The research represents new evidence of the major climate changes Earth has experienced in the past—and is currently undergoing today. The soil in the sediment dates back to the planet’s warmest period of the past 140 million years, with sea level about 170 meters higher than today. The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life. Klages said no ice sheets were present during the time, but seasonal snowfall was likely.

【推荐3】Which of the following books should you read? It is based on your next travel destination.

As you're traveling around Amsterdam , read “The Fault in Our Stars

Previously adapted into a film in 2014 , John Green's story of star-crossed teenagers famously includes a trip to Amsterdam. The Anne Frank House and The Rijksmuseum are two of many major destinations mentioned in the book. Plus, the bench from the film adaptation of this novel has even become its own tourist spot.

“The Elegance of the Hedgehog” is excellent reading for a trip to Paris.

Before wandering down the Champs-lysees, open Muriel Barbery's novel for a delightful look into the lives of wealthy Parisians. Set in a French apartment building, the story follows two totally different people who discover they are kindred souls.

Bring “One Hundred Years of Solitude" to read in South America.

A significant work of literature, Gabriel Garcia Mdrquez’s classic follows generations of the Buendia family as they live in their South-American town. Garcia Marquez's descriptions make the book a perfect read for visiting some of the breathtaking sights of South America.

“Call Me by Your Name” should perhaps be read in the summertime , in Italy .

This novel is said to take place in the Northern-Italian seaside region of Liguria. And if you've seen the 2017 coming -of-age film adaptation of the book, you'll already know the story describes beautiful summers in Northern Italy, complete with seaside encounters and lush greenery.

If you're visiting New York City, enter the mind of Holden Caulfield.

“The Catcher in the Rye” is a classic tale of a lost teenager's unplanned trip to New York City. In the JD-Salinger novel, Holden visits a nightclub in the East Village, goes ice skating in Rockefeller Center , and takes his sister to the Central Park Zoo.

【推荐1】James Gross, a psychology professor at Stanford University, has a 13-year-old daughter who loves math and science. “It hasn’t occurred to her yet that’s unusual,” he says. “But I know in the next couple of years, it will.”

She’s already being pulled out of class to do advanced things with a couple of other kids, who are guys. And as someone who studies human emotion for a procession, Gross says, “I know as time goes on, she will feel increasingly lonely as a girl who’s interested in math and science, and be at risk of narrowing her choices in life before finding out how far she could have gone.’’

Gross’ concern clearly shows what has been a touchy subject in the world of science for a long time: Why are there still so few women in science, and how might that affect what we learn from research?

Women now make up half the national workforce, earn more college and graduate degrees than men, and by some estimates represent the largest single economic force in the world. Yet the gender gap in science persists, to a greater degree than in other professions, particularly in high-end, math-intensive fields such as computer science and engineering.

According to US Census Bureau statistics, women in fields commonly referred to as STEM (science, technology, engineering, mathematics) made up 7 percent of that workforce in 1970, a figure that had jumped to 23 percent by 1990. But the rise essentially stopped there. Two decades later, in 2011, women made up 26 percent of the science workforce.

【推荐2】When I was growing up, I had an old neighbor named Doctor Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard, but was always very kind.

When Doctor Gibbs wasn’t saving lives, he was planting trees. He had some interesting theories about planting trees. He hardly watered his new trees, an attitude which flew in the face of conventional wisdom.

Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said he had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water.

So, instead of watering his trees every morning, he’d beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the trees’ attention.

Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some 25 years ago. They were tall and strong.

Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to encounter hardship. There’s always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won’t be torn apart.

【推荐3】Many of us mistakenly believe that it's wrong to think we have any good qualities. We may spend a lot of time blaming ourselves for our negative qualities, thinking that self criticism is the key to improving our performance. However, a constant focus on our supposed shortcomings can stop our efforts to make friends with other people. How can we believe that others could like us if we believe our inner being is flawed (有缺陷)?

If someone seems to dislike you, the reason for that dislike might have little or nothing to do with you. The person who doesn't like you might be fearful, or shallow, or busy or shy. Perhaps you and that person are simply a mismatch for each other at this particular time.

Don't take yourself out of the game by deciding that your flaws are bigger than your good qualities. In fact, some of the very qualities you consider to be flaws may be irresistible to someone else. For all the factors that might cause one person to reject you, there are at least as many factors that will work in your favor with someone else.

You might be thirty pounds over your ideal weight, but you may have a wonderful laugh and a real enthusiasm for life. There are many people who don't mind your extra pounds. You may drive a shabby car, but you might be a great dancer and a loyal friend. There are people out there looking for loyalty, or fun, or sweetness, or wisdom, and the package it comes in is not important. If you are worried that you are not beautiful enough to attract friends, keep in mind that not everyone is looking for physical beauty in their friends. You can decide to feel inferior (自卑) because you don't have much money and you don't drive a nice car. You can believe that this is the reason that you don't have many friends in your life. On the other hand, if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes you as a person.

The point is that you can focus on just about anything and believe it's the reason you do not have friends and cannot make any.
