【推荐2】Americans began their days by eating whatever was most easily available from the earliest days of the United States. These foods often included bread, eggs or leftovers (剩饭).
Today, the feeling of relaxed and comfortable without worries is still an important reason when it comes to breakfast. However, what people eat has changed over time. And some of today's common breakfast foods, such as cereal (燕麦), are the result of advertising (广告).
"People created advertising to sell cereal," says the writer of the book Breakfast: A History. Arndt Anderson adds, "One of the first ways that advertising was successfully used was to make mothers believe that it was okay for their children to eat these instant cereals (速溶谷物食品). It gave working mothers a chance to let kids take care of themselves in the morning."
____________ also played an important part in orange juice becoming a morning drink. In 1916, farmers grew more oranges than usual, so advertisers began saying, "Drink an orange." They wanted to make people believe that drinking orange juice was a healthy way to start the day.
As for coffee, it became so popular that some people carried coffee beans with them everywhere in the 1930s.
Researchers think people made pancakes in the morning because they are much quicker to prepare than bread. Cooks could then have to make fresh bread for dinner.
Arndt Anderson hopes more Americans will see leftovers as a breakfast food. She adds that leftovers taste good and are a great way to make less waste.

Once upon a time carrots were purple, there were no pineapples in Asia or lemons in America, and many people thought potatoes were poisonous (有毒的). Many types of fruit and vegetables like chili grew only in one place. So why are they all over the world?
Five thousand years ago, carrots only grew in Afghanistan and most were purple. Only a few were orange as they look like today! Farmers in the Netherlands were looking for a fruit or vegetable to stand for their king, William of Orange, and orange carrots were just what they were looking for—they became the grandfather of all modern carrots.
Many plants only grow in certain places on Earth, often deep in the forest. The home of potatoes is in the mountains of the Andes in South America. Bananas come from Papua New Guinea and lemons grow wild in China. Corn isn’t from China, but South America.
But once people realized that many of these plants were good to eat, they took them far from the places where they grew. Fruit, especially, interested thirsty travelers. Arab businessmen transported different fruits and vegetables around the world, such as oranges, which they took from Asia to countries far away such as Spain. The Spanish returned from South America with many new types of food, including chocolate and chili.
People were not often sure what to do with these new fruits and vegetables, or used them for different purposes from today. Carrots were used not as food but as medicine to protect people from poison or even (it was believed) to make people fall in love. The first tomatoes and pineapples were grown not as food but to make the garden look pretty. And many people were worried about potatoes—although they are good for us, their leaves are poisonous and poorer people believed they could be used for black magic. In Germany, people only began eating potatoes when the king ordered that people who did not eat them would have their ears and noses cut off!
Today, we are so used to our different types of food that we don’t think about where they came from. But for each pineapple, potato or carrot we eat, there is a long history!

As the days get colder, the flu season comes. The sneezes (喷嚏) from people who have a cold sometimes smell unpleasant. Where does the smell come from?
In fact, the thing we sneeze out is mostly our saliva (口水). Saliva is 99.5 percent water and 0.5 percent other things like protein (蛋白质) and minerals (矿物质). When some bacteria (细菌) come into your mouth, they break down some protein in your saliva. This process sometimes produces gases (气体) like volatile sulfur compounds (VSCs, 挥发性硫化物) a group of unpleasant gases. Normally, they stay in the saliva. But when we sneeze out saliva, the water evaporates (蒸发) quickly in the air, letting out the gases and setting free bad smells.
Moreover, when we sneeze, it’s not only saliva that comes out but also some things in the nose and throat. For those who have a cold, there are probably snot (鼻涕) and sputum (痰) filled with bacteria in their noses and throats. Pushed by the air pressure from sneezing, they may get out together with saliva, providing a mix of different bad smells. That’s why you can smell more unpleasant sneezes in the classroom during the flu season.
Anthony G. Del Signore, a senior medical expert from Israel, told livestrong. com that different smells of sneezes have different causes.
Diabetes (糖尿病) might lead to sweet smelling sneezes. Bacteria and infections (感染) inside the nose would result in smelly ones. And teeth illnesses are likely to cause sour smells. Serious diseases that include liver (肝) and kidney (肾) problems may cause sneezes to smell really bad, like a toilet.
Does this worry you? A smelly sneeze every now and then is common. But if your sneezes smell bad for a long time, it's time to go to a doctor.
THE BEST WAY TO SNEEZE
The US Centers for Disease Control and Prevention (美国疾控中心) says that you should cover your nose and mouth with a tissue (纸中) when sneezing and then throw the tissue straight into the bin (垃圾桶). But if you don’t have a tissue at hand, sneeze into your elbow (肘) instead of your hand. After all, you won’t greet others and touch things around using your elbow! This helps lower the risk of making the people around you sick.

【推荐3】There are many ways to help improve your health like eating healthy food. Taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night.
The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. Also sleep problems can cause medical problems such as high blood pressure(血压).
Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. It seems that the less you sleep, the more work you’ll do.
How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert (专家) in sleep. He says , “Sleep is like a credit (信用卡) card. When you sleep less. you are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card. ’”
For those who value work more than sleep, they should listen to what a famous person once said. “Don’t think you will be doing less work because you sleep during the night. That is a foolish(愚蠢的) idea which is held by people who have no imagination. You will be able to do more.”

【推荐1】Malaria (疟疾) has been a big problem for humans since ancient times. Usually, people get malaria when infected mosquitoes (被感染的蚊子) bite them. Many people have died from the disease. Luckily, Chinese scientist Tu Youyou found an effective drug (药) called qinghaosu (青蒿素).
In 1969, Tu became the director of a national project to develop the medicine to treat malaria. They studied books about classical Chinese medicine. After reading more than 2,000 old remedies (药方), Tu and her team collected over 600 plants and listed almost 380 possible remedies for malaria.
One remedy, which is 1,600 years old, uses sweet wormwood (青蒿) as a treatment. Tu found it worked and tried to extract (提取) the qinghaosu from it to make a drug. The extraction failed at first, so Tu returned to the classical books again and finally found a way.
She used a low - temperature method to extract the qinghaosu and finally succeeded in 1972. After her team showed that qinghaosu could treat malaria in mice and monkeys, Tu and two of her coworkers decided to test the drug on themselves before trying it on human patients. It turned out that qinghaosu was safe, and all patients in the test got better. Gradually, qinghaosu became the first - line treatment for malaria recommended (推荐) by the World Health Organization (WHO), saving millions of lives around the world.
In 2015, when Tu was given the Nobel Prize in physiology or medicine, she refused to take all of the praise. Instead, she praised her coworkers and Chinese traditional medicine. She once said, “Every scientist dreams of doing something that can help the world.”

【推荐1】Are you new to experiencing relationships? Well, let me give you some advice on having a healthy and possibly long-term relationship.
Be an honest person with them. Do not hide things from them; do not lie. Getting them to trust you is the most important thing in any relationship. If there’s no trust, there’s nothing there. So please be honest and they’ll learn to open up to you.
Make sure you give them respect. Now respect isn’t just simply treating her or him nicely. There’s a lot more to it. You should learn to study your partners’ wants and needs. Don’t just think about yourself; think about what your partners need as well.
Make sure you are encouraging to your partners. Always be willing to help them and give them honesty and positivity at the same time. Make them feel you are someone who they can really count on. It means your partner can depend on you when they need help. This is an important step in a relationship.
Make sure you have a good sense of humor with them. Laughter is the key to happiness. Laugh a lot with them, and joke with them. Laughter may seem silly, but it’s the secret to a lot in life. It will keep the sparks alive. Laughter keeps the relationship strong and lasting.
Make sure the communication is good. Always communicate how you feel, even if it’s something that upsets you. Instead of screaming, talk to them. If they did something that made you unhappy, tell them about it in a respectful manner. It’s important to communicate this to them, not to keep it bottled up (压制情绪).
