While some extreme diets may suggest otherwise, we all need a balance of protein, fat, carbohydrates, fiber, vitamins, and minerals in our diets to keep a healthy body. You don't need to remove certain kinds of foods from your diet, but rather select the healthiest ones.
Protein: protein gives us the energy to get up and go — and keep going — while also supporting mood and cognitive (认知) function. Over protein can be bad to people with kidney disease, but the latest research suggests that many of us need more high-quality protein, especially as we age. That doesn't mean you have to eat more animal products — many plant-based sources of protein each day can ensure your body gets all the necessary protein it needs.
Fat: not all fat is the same. While bad fat can destroy your diet and increase the possibility of certain diseases, good fat protects your brain and heart. In fact, healthy fat — such as omega-3s —is necessary to your physical and emotional health. Understanding how to include more healthy fat in your diet can help improve your mood and your well-beings.
Fiber: eating foods high in dietary fiber (grain, fruit, vegetables, nuts, and beans) can help you stay regular and lower the possibility of heart disease, strokes, and diabetes. It can also improve your skin and even help you to lose weight. Depending on your age and gender, experts suggest you eat at least 21 to 38 grams of fiber each day.
Calcium(钙): your body uses calcium to build healthy bones and teeth, keep them strong, send messages through the nervous system, and control the heart's rhythm. Not getting enough calcium in your diet can also lead to anxiety, depression, and sleep difficulties. Whatever your age or gender, it's necessary to include calcium-rich foods in your diet.
When her five daughters were young, Helene An always told them that there was strength in unity(团结). To show this, she held up one chopstick, representing one person. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.
Helene and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Afterwards, Helene and Diana changed it into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.
Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."
Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes over $20 million each year. Although they began with a small restaurant, they had big dreams, and they united. Now they are a big success.
A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species.
The discovery was made by researchers at York and Harvard Universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant.
Once they obtained DNA sequences (序列) from two fossils (化石), mammoths and mastodons, the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants' significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, "We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950, all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose ."
One might expect that the evergrowing demands of the tourist trade would bring nothing but good for the countries that receive the holidaymakers. Indeed, a rosy picture is painted for the longterm future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month, another rockbound Pacific island is advertised as the 'last paradise on earth'.
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of seaside holidays, overcrowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holidaymakers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The onetime farmer is now the servant of some multinational organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and actually obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next decade will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning worldwide tourism can preserve the market for them. If not, in a few years' time the very things that attract tourists now may well have been destroyed.
In your life, sometimes you may be asked to speak in front of a large group of people. Although it sounds a little scary, even those with stage fright can speak successfully to the group with adequate preparation.
Practice your speech before the big day. If possible, practice the speech in front of a friend or family member to get used to saying it to real people. If you feel you must have note cards, limit the amount to about three cards. This will force you to keep your speech concise and help you keep your eyes focused on your audience.
Remember why you've been invited to speak. If you're battling fear over speaking to a large group of people, keep your mind on the fact that you were selected for this important role. The speech organizers must have seen something valuable in you or your expertise.
Remember that fear of public speaking is very common.Most of the people in the audience would be feeling the same fear and stress that you do in your position. Knowing this may make you feel better.
What you say should be tailored to why you're there and who you're speaking to in order to avoid sounding general. If speaking to a charity group, mention the good work certain specific individuals have done for the cause. If speaking at a business conference, briefly state why you want to help these people.
Keep eye contact with the crowd. Pick one person in each section and look at him while you're speaking. After each important point in your speech, switch your focus to another section. When you focus only on one person at a time, the size of the crowd isn't as frightening.
A. A good memory is really helpful.
B. Show appreciation to your audience.
C. Mention your audience in your speech.
D. The more you have, it memorized, the better.
E. In fact, it's normal to feel nervous or stressed out before a big speech.
F. Separate the crowd into three sections mentally as you get up to speak.
G. The knowledge of other people's respect for you should reduce some of the fear.
When a young woman in Texas learned that her dad's small business was bad during the pandemic(疫情), she made a request on Twitter asking for help.
"I wouldn't1do this, but my dad's taco(墨西哥玉米薄饼卷)truck business is2. He only sold $ 6 today," Giselle Aviles, 21, wrote in a twitter about her father's taco truck. "I would3it so much if you could retwitter!"
When the pandemic hit, the food truck's sales began to4. Like Aviles' father, many small business owners throughout the country continue to struggle through the pandemic. More than 100, 000 small businesses have5and that number is on the rise.
But Aviles' social media request6—by Sunday night, the post had gained around 2,000 retwitters. She told her father that he should prepare for many new7when the truck opened the next day. Her father didn't understand social media, so he didn't know what to8.
When he arrived at his food truck at 8 a.m. on Monday, a line of customers were there-some had been9as early as 6 a.m. Business was so10that the food truck had to close down twice-once to restock (补货) and again when they were11sold out. He even asked his daughter to help with the12.
Aviles estimates that her dad13more than 200 customers on Monday. She says she appreciates the14 for her dad's business and has since made an Instagram page for more customers to find his15easily.
Last night, I witnessed the first of only eight (perform) of Giacomo Puccini's world-famous opera, Turandot, being performed in the Forbidden City in Beijing, China. ust imagine performing such opera in the Forbidden City —there could not be a more awesome setting! In the story, the emperor of China, Turandot's father, has promised to allow her to choose her own husband. In order to avoid marriage, she says that any potential husband must solve three riddles if he wants to marry her. Those cannot answer all three riddles will be condemned death. This means that few men would dare to ask for her hand in marriage. The story begins when a prince is killed for failing to solve her riddles. The emperor finds the death (disturb).
Shortly afterwards, another prince, Calaf, falls in love with Turandot at first sight and decides (solve) the riddles so that he can marry her. Meanwhile, Liu expresses her love for Calaf. Calaf answers the three questions. Turandot becomes very angry as she is unwilling to get
(marry). (see) this, Calaf says that if she can guess his name, she will not have to marry him. So Turandot demands that Calaf's father and Liu tell her Calaf's name or they (beat). Liu claims that she alone knows the name.(unfortunate), she chooses to kill herself. Calaf scolds Turandot for not being more merciful. However, he still loves her. At last, they unite in marriage.
I lay on my bed, legs leaning against the wall, desperately wishing my mother would call. But I remembered the last time I'd seen her, right before the train for Providence pulled out of the station, "You know how expensive it is to call," she said, then hugged me tight and said good- bye.
This was my first birthday away from home. I missed my mom, missed my sister, and most certainly missed the special pound cake my mother always made for my birthday. Since getting to college that year, I would watch jealously as the other freshmen received care packages from their parents on their birthdays——and even on ordinary days. Big boxes containing summer slacks and blouses, packages of M&M's and Snickers, things they needed and things they didn't. Instead of feeling thrilled about my upcoming eighteenth birthday, I felt empty. I wished my mom would send me something, too, but I knew that she couldn't afford presents or the postage. She had done her best with my sister and me——raising us by herself. The simple truth was there just was never enough money.
But that didn't stop her from filling us with dreams. "You can be anything you want to be," she would tell us. "Politicians, dancers, writers —— you just have to work for it; you have to get an education."
Thanks to my mom's sacrifices and big dreams, I'd made it to the Ivy League: Brown University in Providence, Rhode Island.
As I was recalling these things, my roommate joined me on the bed. "Hey. After we study, let's buy ice cream and cake." I nodded, closed my eyes, and imagined the cake Mom would have made. Mmm. I could see the golden yellow of each of the twelve eggs, and I could almost smell the vanilla(香草) filling the house while the cake baked.
