Three years ago, I got the chance to spend a month as a volunteer helping out in a hospital in Africa. I had one month left at high school, and I was interested in studying medicine at university. I thought it was the perfect chance to get some practical experience and to see if I really wanted to be a doctor.
It was a month that changed my life. I was introduced to a new world that is very different to mine in so many ways. I was horrified at how poor so many of the families over there are and how difficult their lives can be. But I was even more amazed at how positively people go about their everyday lives in Africa. The way they come together and help each other is a real inspiration, and something I think a lot of us have forgotten in the United States. I think many of us don't realize how lucky we are.
My work in the hospital was hard. I spent a lot of time washing floors, cleaning toilets and changing bed sheets. I also got to spend some time looking after the patients. But it was such an honor for me to listen to a patient's story and communicate with people from so many walks of life. And I also got the chance to talk to some doctors and ask them about the profession. I saw some truly awful things in the hospital, but none of them changed my mind about being a doctor. In fact, they only made me more determined to do medicine.
It has been a great experience volunteering in Africa. When I finish, I know exactly what I'm going to do：I want to work for an international organization like the Red Cross and spend my life helping people who haven't been as lucky in life as me. I can't wait to get started.
Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin?Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plates are empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food leisurely and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Even their fast-food meals are lengthy compared to the typical American's. A study in Psychological Science found that Parisians who dined at McDonald's spent an average of 22 minutes eating, while Philadelphian McDonald's-goers were in and out in just 14 minutes. Mercola believes Americans lose the ability to sense when their stomachs are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal. After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17%-and is growing.
Commercial airlines alone contribute around 3% of total global carbon emissions. But the industry is actively looking for green solutions in the form of sustainable jet fuel, and in one case, that fuel may have had a previous life as your household food waste. In a study released this week in the Proceedings of the National Academy of Sciences, researchers detail a method of transforming food waste into sustainable jet fuel that can be used in existing engines.
Biomass（生物质）, such as manure（粪便）and food waste, can be transformed into bio-fuels, which are renewable liquid fuels made from organic matter. Derek Vardon, a senior research engineer at the National Renewable Energy Laboratory （NREL）, says that their fuel worked as a mixture of 90% conventional petrol jet fuel and 10% alternative jet fuel required by the industry currently. They also show they could push it to a 70/30 mixture, which will be possible in real world with more time and testing.
Major airline companies are eager to get involved in sustainable aviation fuel because some sustainable solutions, such as battery-operated commercial planes, just aren't possible yet with current battery technology. A battery-powered plane would be too heavy to fly long distances, so fuel that works in the same way as the fuel we have is a simpler way to trade out emission-heavy fossil fuels.
Vardon says that because the wet waste used in the process would normally go to a landfill（垃圾填埋场）and break down to release greenhouse gases, the process of making and using sustainable aviation fuel could actually have a negative carbon footprint when scaled up.
Commercial airlines are on board to find an affordable and sustainable solution to the carbon-intensive process of air travel. Airlines are looking to hit aggressive sustainability goals by 2050, including decreasing net carbon dioxide emissions by 50%.
Why is Eating Colourful Food Good for You?
Most of us are faced with the same choice numerous times a day：what to eat. Along with price, accessibility and preference, we'll often use a food's healthfulness to help us make a decision.
It's widely accepted by researchers that we need a varied diet. The proof may be in the Mediterranean diet, which contains a lot of fruit, vegetables and healthy fats such as extra virgin olive oil, and is frequently rated the healthiest diet by scientists.
Eating lots of colours may lower your risk of missing out on all vital nutrients. "If we're missing a colour of the rainbow, we may be missing a function of that food, "says Minich. This is because plant foods contain thousands of natural compounds, which have anti-inflammatory（抗炎的）benefits.
Blue and purple foods, including blueberries, have a high content of the plant anthocyanin（花青素）, which has been linked to lowering the risk of heart disease and type 2 diabetes. Flavones（黄酮类化合物）, which give foods a yellow colour, may reduce the risk of heart disease.
A research fellow at Harvard TH Chan School of Public Health says eating a colourful diet can also help people avoid possible side effects of eating too much of one food. " For example, research has found that orange juice is associated with a lower risk of cognitive decline, but too much intake is associated with type 2 diabetes, "she says. Although, this is because of its sugar content, not flavonoids（黄酮类）.
Eating a rainbow diet may also be complex. We could get into trouble. We also need to eat from other food groups to get all the nutrients we need, such as protein.

A. Food is very complex. B. A varied diet is packed with different vegetables. C. Different coloured foods come with different benefits. D. But how do we know we're getting enough nutrients? E. It could be really difficult to get every colour every day. F. However, is colour the best guide to getting all the nutrients? G. And one way to do this is by eating all the colours of the rainbow. |

Researchers say they have found microplastics （微塑料） -tiny pieces of plastic that come as a result of the disposal of industrial waste-deep in the lungs of living （ human） for the first time.
The research, which （ publish） in the journal Science of the Total Environment last week, is the first study （ identify） the plastics in the lungs of living people. The plastics have （ previous） been found in human blood, waste and in the depths of the ocean.
In the study, researchers （ collect） lung tissue from surgical procedures on patients as part of their routine medical care. Researchers identified 12 types of microplastics, are commonly found in bottles, packaging, and clothing, along with other manufacturing processes.
The study notes "increasing concern" with the harm that could come with swallowing and breathing in microplastics.
The world produces about 300 million metric tons of plastic a year and about 80% ends in landfills and other parts of the environment. Microplastics can range from 10 nano-meters- （ small） than the human eye can see-to 5 millimeters in diameter, about the size of the eraser on the end of a pencil. Researchers have found them （ float） in the air, in tap or bottled water, and in the sea or soil.

When the night fell, James, a middle school student in London, dragged his tired body home. In order to save money to buy himself a new bike, he had been working at a restaurant for over a month during the summer vacation. He had already earned some money. With one more week, he would have his dream bike.
Entering the room, James found his younger brother Adam sitting on the edge of his bed with an uneasy expression on his face. James stared at Adam confusedly.
"Sorry. I did something wrong, " Adam said, on the verge of tears.
"What's the matter with you?" James asked.
"This afternoon I went to play football on the road outside the house and accidentally hit our neighbor Mr. Black's car. I was so scared and I hurried home in panic without telling him, " Adam said, full of guilt.
"Is the car seriously damaged?" James couldn't wait to continue asking.
"The ball hit the car back and the tail light got broken, " Adam said in a low voice.
"It's truly your fault. It's really dangerous to play football on the road. What's worse, you shouldn't have come back without telling Mr. Black about it. You are such a naughty boy, " James raised his voice. Hearing this, Adam lowered his head and bit his lips hard. James added, "Anyway, it's never too late to mend. I'11 take you to his house tomorrow to apologize. Now it's time to sleep. "
When Adam went bed, James couldn't go to sleep himself. Father always told him to be honest, to be a boy admired by the people and to be an example of his brother. He was sorry for his brother's behavior. He shouldn't have blamed his brother after he did something wrong. But he could understand him. Anyway, Adam was only a boy of seven and what had happened really scared him. But as his elder brother, he should pay for it though this might delay his plan of having the bike. "Nothing serious. At worst, I can take more summer jobs, " he said to himself.
