Can energy drinks really make you energetic? A survey, by Cancer Council Australia among more than 9000 students across the country, found teenagers who were bitten by the energy drinks bug and drank energy drinks at least once a day were twice as likely to get less than eight hours' sleep on school night than those who didn't.

The same survey found one in six teenagers take in at least 5.2kg of sugar each year from sugary drinks alone. "This can lead to weight gain and obesity, increasing the risk of heart and kidney disease, type 2 diabetes, stroke and some cancers," Mr Sinclair said, who led the survey. Craig Sinclair, head of Rethink Sugary Drink, said the levels of sugar in energy drinks are very high, causing teenagers to put on weight.

The survey also found the caffeine （咖啡因） levels of the drinks is also high and this could explain the survey results on their effect on teenage sleep. Energy drinks contain 160mg of caffeine, more than twice as much as a cup of coffee or a 500ml bottle of cola, Mr Sinclair said. The Sleep Health Foundation says teenagers need 8-10 hours of sleep, more than an adult, because their bodies and cognition are growing rapidly. Sleep is important for teen mental health and the US Sleep Foundation says shortage of sleep can contribute to acne, bad behaviour and unhealthy eating habits. Associate Professor Matthew Hoperaft from the Australian Dental Association Victoria said energy drinks are also a major contributing factor to tooth decay and tooth erosion.

Royal Prince Alfred Hospital heart doctor Professor Chris Semsarian has tested the effects of energy drinks on the heart and said they can lead to an increased heart rate and irregular heart beat. "Caffeine is not the only stimulant （兴奋剂） part of these drinks, most also have guarana which is also a stimulant," he said. Energy drinks have been related to scores of deaths around the world because of their high caffeine content.

Carol Heffernan, a 43-year-old woman from Oshkosh, regularly felt worn out from working, sending her two kids to school and playdates, and taking care of housework. But after the COVID-19 hit in March 2020, the kids were suddenly at home all day and learning remotely, her common weariness quickly turned into full-on exhaustion.

"It just added up all the extra responsibility and the mental load," she says. "I felt bad-tempered and tired, and it wasn't due to lack of sleep." If there's one thing many of us have in common, it's that we're tired. Doctors even have a name for it, "tired all the time", or TATT for short. The solution isn't always as simple as getting more sleep. Nearly a quarter of people who get seven or more hours of rest a might report that they still wake up feeling tired most days.

A few weeks after her tiredness set in, Heffernan decided to drop everything and go for a walk, which she hadn't done since the pandemic began, "I just want to be myself," she says. "I need a break." When she returned, she felt recharged and decided to make a habit of it.

Doing something active when you're feeling sluggish will actually increase your energy, not consuming the little energy that you have. In fact, researchers a Georgia University found that just ten minutes of low or moderate intensity exercise gave study participants a noticeable energy boost. Exercise also works its magic at the cellular level. The mitochondria （线粒体）, the parts of cell that provide energy to muscles, can grow more powerful and numerous after aerobic exercise, providing a continuous source of increasing energy to help you work hard.

Now, Heffernan goes for a daily 45-minute stroll. "The walks feed me spiritually, emotionally and physically," she says. "I have something to look forward to every afternoon. I'm in a better mood and I'm also energetic. Of course, getting more exercise isn't the only defense against TATT syndrome."

It was one of the hottest days of the season. We had not seen rain in almost a month. The crops were dying. Cows had stopped giving milk. The creeks and streams were long gone back into the earth. It was a dry season that would bankrupt several farmers before it was through. Every day, my husband and his brothers would go about the tiring process of trying to get water to the farm. If we didn't see some rain soon, we would lose everything.

It was on this day that I learned the true lesson of sharing and witnessed the only miracle I have seen with my own eyes. I was in the kitchen making lunch for my husband and his brothers when I saw my six-year old son, Billy, walking toward the woods. He wasn't walking with the usual carefree abandon of a youth but with a serious purpose. I could only see his back. He was obviously walking with a great effort trying to be as still as possible. Minutes after he disappeared into the woods, he came running out again toward the house. I went back to make sandwiches, thinking that whatever task he had been doing was completed.

Moments later, however, he was once again walking in that slow purposeful stride toward the woods. This activity went on for over an hour: walking carefully to the woods, and then running back to the house. Finally, my curiosity got the best of me. I crept out of the house and followed him on his journey.

He was cupping both hands in front of him as he walked, very careful not to spill the water he held. Maybe two or three tablespoons were held in his tiny hands. I sneaked(slipped) closer as he went into the woods. Branches and thorns slapped his little face but he did not try to avoid them. He had a much greater purpose. As I leaned in to spy on him, I saw an amazing sight. A mother deer with a huge pair of deer horns appeared in front of him, with a baby fawn（幼鹿）lying on the dry ground. I almost screamed to get him away.

An Exchange Visit

Numerous Chinese cultural and art treasures  (put) on show in many parts of the world over the past years, showcasing the fantastic Chinese civilization on the global stage and  (promote) cultural exchanges.

In December, 2018, New Zealand's national museum started a four-month exhibition, where both terracotta warriors（兵马俑）and more than 160 ancient antique pieces (make) of gold, jade and bronze were displayed. On the opening day, local citizens lined up to enjoy this "once in a lifetime" experience. The exhibition, provided visitors with some knowledge of long standing Chinese civilization, was (high) appreciated for the individuality of each terracotta warrior and the (believable) creativity needed to build the army.

Treasures showing the lives of emperors and empresses from the Qing Dynasty also went on display in museums in Washington. D. C.and Moscow in 2019,  over 100 pieces put on show, including realistic  (painting), furnishings and jewelry from the Palace Museum in Beijing. The exhibition was also a huge success.

Chinese and foreign museums have been making exchanges  64  (encourage) dialogue between civilizations and foster people's understanding of and engagement with cultures that interest (they). It is an important job for museums to bring the world closer.

My brother Ken was born with a brain disease. Though Mama was extremely loving, she never babied Ken. She 1  him to do whatever we did.

I remember once we got a slide in our backyard. Ken was 2  at first sight. But unable to 3  the steps with the braces（支架）on his legs, Ken could only look up at the rest of us from the ground.

One day, Mama put Ken in the backyard, this time without his braces, and watched him 4  with great difficulty right over to the slide. For the next three hours, Ken climbed the ladder and fell, climbed the ladder and fell, 5 . He skinned his knees, and his head was bleeding.

Our neighbor 6 at Mama, "What kind of woman are you? Look at the blood. Get that boy off that ladder!" Mama told her kindly that if it 7 her, she would have to close her curtains. Ken had decided to go down the slide, and down the slide he would go. It took a couple of days of 8 before he could go up the ladder and down the slide as well as the rest of us, and another week before he could do it with his braces on.

Ken was not supposed to make it to his tenth birthday but he has 9  his disease and is now a 42-year-old man who lives 10  and even holds down a job. He 11  everything the way he did that slide so many years ago. What a(n) 12  Mama gave him that day by expecting him to be the 13  he could be.

Though I often feel I fall short when I compare my 14 to hers, it gives me great comfort to know that her spirit is 15 me, somewhere—preparing me to make "mothering magic" of my own.

One of the greatest biologists the world has ever seen was Charles Darwin. Darwin was born to a middle-class family in Shrewsbury, England, in February, 1809. His father was the leading doctor of the town.

 He loved to walk through the woods looking at plants and birds. At the proper age, he was admitted into Shrewsbury School. There he studied Latin, classical literature, and ancient history. Young Charles thought that these subjects were dull and useless. He would have preferred scientific studies. As a result, he did poorly.

In 1825, at the age of sixteen, Darwin was sent to Scotland to study medicine. He once wrote to his sister that his medical courses were completely stupid. By then, Darwin's father knew that his son would never become a doctor.

Darwin's father then sent him to Cambridge to become a clergyman（牧师）.During his Cambridge years, Darwin loved to collect beetles（甲壳虫）,but to him it was only a hobby. He didn't take it seriously.

 That was Professor John Henslow, the head of the Botany Department. Somehow, Darwin managed to graduate from Cambridge in 

1831. Upon graduation, Professor Henslow arranged for him to go with Captain Fitzroy on a survey trip around the world. During the voyage, Darwin collected rocks, bones, and insects. He took many notes on all that he observed. 

The widely believed theory in those days was that God created each creature separately and individually. In it, he explained his theory of evolution by natural selection. The theory was instantly and very strongly attacked. Darwin was accused of destroying religion and insulting（侮辱）the human race. Today, however, Darwin's theory is considered to be one of the major discoveries of modem science.

A new study suggests drinking coffee as soon as someone wakes up from a poor night's sleep greatly affects metabolism（新陈代谢）and blood sugar control.

In the study, published in the British Journal of Nutrition, UK researchers let 29 healthy men and women take part in three different overnight experiments. In the first two scenes, participants were given a sugary drink upon waking — first from a normal night's sleep, and then again after a poor night's sleep during which they were woken up for five minutes every hour. In the third, their sleep was similarly disrupted, but they were given a strong black coffee 30 minutes before consuming the sugary drink.

Blood samples from participants were taken following the sugary drink, which mirrored the calories of a typical breakfast, in each experiment. Results showed that one night of disrupted sleep did not worsen the participants' blood sugar responses at breakfast when compared to a normal night of sleep. However, strong black coffee consumed before breakfast increased the blood sugar response by around 50 percent.

By drinking such kind of drink after breakfast, UK researchers found that our bodies' ability to break down our food healthily is completely improved. Examining the effects of broken sleep and morning coffee across a range of different metabolic markers, scientists at the University of Bath found that, while one night of poor sleep had a limited effect on metabolism, drinking coffee before breakfast could have a negative effect on blood sugar control.

"We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee — the more tired we feel, the stronger the coffee is. This study is important and has far-reaching health influences, and it indeed moves some coffee drinkers' heartstrings. As up to now we have had limited knowledge about what this is doing to our bodies, in particular for our metabolic and blood sugar control, so we have a long way to go." said Professor James Betts, co-director of the Centre for Nutrition, Exercise and Metabolism at the University of Bath.

Technology seems to discourage slow reading. Reading on screens tires eyes easily. So online writing is more skimmable than print. The neuroscientist Mary Walt argued this "new norm" of skim reading is producing "an invisible, dramatic transformation" in how readers process words. And brains now favor rapid absorption of information, rather than skills developed by deeper reading, like critical analysis.

We shouldn't overplay this danger. All readers skim. Skimming is the skill we acquire as we learn to read more skillfully. And fears about declining attention spans have proved to be false alarms. "Some critics worry about attention span and see very short stories as signs of cultural decline," The American author Selvin wrote. "But nobody ever said poems were evidence of short attention spans."

Yet the Internet has certainly changed the way we read. First, it means there's more to read, because more people than ever are writing. And digital writing means rapid release and response. Once published, online articles start forming a comment string underneath. Such mode of writing and reading can be interactive and fun, but is probably lacking in profound reflection.

Perhaps we should slow down. Reading is constantly promoted as a source of personal achievement. But this advocacy emphasizes "enthusiastic" or "eager" reading — neither suggest slow absorption. To a slow reader, a piece of writing can only be fully understood by immersing oneself in their slow comprehension of words. The slow reader is like a swimmer who stops counting the number of pool laps he's done and just enjoys how his body feels and moves in water.

The human need for this kind of deep reading is too determined for any new technology to destroy. We often assume technological change can't be stopped, so older media are kicked out by newer, more virtual forms. In practice, older technologies can coexist with new ones. The Kindle hasn't killed off printed books any more than cars killed off bicycles. We still want to enjoy slowly-formed ideas and carefully-chosen words. Even in a fast-moving age, there is time for slow reading.
