A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations（语调）of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted（闪烁）at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up – the product of his sacrifice.

And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment. "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) – to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative（故事）of upward mobility so your children can do the same.

I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    A little boy discovered what looked like a map to an unknown place. He soon realized it was the beginning of an exciting treasure hunt.

    He found two pieces of paper along with the mysterious map. One was written with the instructions, “FIND THE WORDS.” The other piece of paper had several strange symbols scattered all over it.

    Dad, fortunately, was there to help his son figure out the mystery. He folded up the paper with the symbols on it, and together they formed a message, which had another set of instructions, “UNDER STEPS.” The smart little boy knew exactly what to do so he went to look under the steps of his house. Without too much effort, he found a box below the staircase.

    It didn't take him long to figure out what to do next: open it up! Inside the box were some very interesting objects, including another piece of a treasure map and two broken pieces of paper. These were the most interesting finds because they contained what appeared to be a collection of letters on them. Finally, they knew where the treasure was from the letters: IN THE BUSH UNDER YOUR YARD.

    After searching all over the yard, following several clues and wondering where everything would lead, the pair finally found what they had been looking for. And it was exactly what you would want after such an adventure: a treasure box!

    The pair pulled it out of the ground and cleaned away all the dirt. The dad put the box in front of his son, and the little boy couldn't contain his excitement. So he opened it up and finally found out what was inside.

    Inside was more treasure than any little boy could ever want. There were hundreds of coins and all sorts of pirate treasure, including what looks like a pearl necklace and some silver dishes.

    I've recently published a book of letters from 32 amazing Australian women about their experiences of new motherhood. Perhaps the most common question I've been asked since publication is why more of the mothers didn't ask for help. If those early months were so hard and so exhausting as they were described, then why didn't more of these women simply ask for help?

Embedded (把……牢牢地嵌入) deep in this enquiry is the assumption that if you ask, you shall receive—and that you shall receive without judgment. And if there is any experience of new motherhood in the 21^st century it is the inescapability of judgment. By asking for help new mothers open themselves up to a wave of quiet—and not-so-quiet—disapproval of why on earth they need it.

    The earliest moments of motherhood are synonymous with sacrifice(等同于牺牲). A mother sacrifices her body for not nine but almost ten long months, sharing her shell with a new being. A mother sacrifices her control, and often her mental and physical health, during the painful process of childbirth. A mother, in the weeks and months that follow, puts the needs of another before her own, sacrificing her sense of self, her ambition and all too often, her happiness.

    We don't normally use the word sacrifice to describe the newborn period. It's supposed to be sweet and milky and warm but a sacrifice is exactly what it is. And when we sacrifice we should be entitled (使享有权利) to mourn—a privilege new mothers are expressly prevented from.

    We have reached the point where being a mother who admits she needs help is like saying your child isn't worth the sacrifice. The suffering has become a badge(徽章) of honor, worn in service to your family.

    The role of mothering is not an easy one, nor will it ever be. But it could be made more manageable if we were all to offer help or support.

    We often seek food after focused mental activity, like preparing for an exam. Researchers guess that too much thinking consumes a lot of energy from the brain. So the brain, sensing that it may soon require more calories to keep going, apparently leads to bodily hunger, and even though there has been little physical movement, we eat.

    The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.

    Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.

    Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was. Afterward, they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted. At a later date, the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.

    Next, half the students sat quietly for 15 minutes, before being given pizza. The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking, repeated five times. These students were then allowed to gorge on pizza, too. But by and large, they did not overeat.

    When the researchers factored in(将……作为因素考虑)the calories burnt on running, they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.

    The researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as running, although the researchers say they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hungers call.

"I have not failed. I've just found 10,000 ways that won't work." Those are the words of Thomas Alva Edison, one of the greatest {#blank#}1{#/blank#} (inventor) in the history of the United States.

Edison, who grew up in the Midwest, was {#blank#}2{#/blank#} (large) self-educated. He earned 1,093 patents in his lifetime, including the lightbulb. Being {#blank#}3{#/blank#} successful businessman, Edison often reworked existing technology, making it more practical for widespread use.

Edison was born on February 11, 1847, a day that {#blank#}4{#/blank#} (celebrate) as National Inventors' Day today. The Thomas Edison Center, which was created in memory of Edison, is at Menlo Park in New Jersey. It is said that the seven years Edison spent at the lab he created in New Jersey were the most {#blank#}5{#/blank#} (product).

"Menlo Park is the birthplace of {#blank#}6{#/blank#} (record) sound. It was in Menlo Park {#blank#}7{#/blank#} Edison invented the phonograph （留声机） in 1877. The invention led to the 30-year-old Ohio native's international fame. From then on, he was known {#blank#}8{#/blank#} the "Wizard （奇才） of Menlo Park."

A phonograph was the first device that was used {#blank#}9{#/blank#} (reserve) sound. It was the precursor （先驱） to record albums and CDs. The original model had no volume knob （旋钮）, so listeners would have to control the sound by {#blank#}10{#/blank#} (place) a sock in the machine. That's where we get the expression "put a sock in it", which means "stop talking".

Nowadays, the term "superfood" has become the nutritional buzzword. Simply put, these superfoods are those that provide large amount of nutrients through minimal calories. 

The term "superfood" may have taken the modern food scene by storm. {#blank#}1{#/blank#} Although only popular in recent years, the concept of certain foods with special nutritional qualities has been around for a long time. The nickname "superfood" gained widespread popularity in the early 2000s as health enthusiasts and the food industry sought to identify and market foods with special health benefits. Today, it is a trend in diet. 

In an age when we share all kinds of superfoods on social media, ignoring the phenomenon is impossible. {#blank#}2{#/blank#} It's easy to understand. These nutritional superheroes offer a perfect combination of substance and style, tailored for the digital generation. Their lively colours, exotic origins and impressive nutrient profiles make them candidates for the next viral food trend. 

{#blank#}3{#/blank#} They offer a lifestyle that reflects the global shift towards a more healthconscious society. As the world wrestles with an increasing burden of diseases and the fast pace of modern life, people are seeking dietary solutions from superfoods. {#blank#}4{#/blank#} They are rich in vitamins and minerals that can strengthen your immune system, avoid chronic diseases, and improve your overall wellbeing. Another remarkable benefit is their potential to promote heart health, helping you build a strong heart. Don't forget their role in skin regeneration. The antioxidants(抗氧化物) can provide a natural glow, reduce skin ageing and fight against skin conditions. 

{#blank#}5{#/blank#} Superfoods, while nutritionally dense, should be part of a comprehensive diet rather than the only guarantee of our health.
