1 . As the weather changes from day to day, sometimes it's impossible to avoid catching a cold or the flu. However, that doesn't mean we have to suffer terribly. Since the only way to get better from a cold is to go through the process, many natural remedies (疗法) have helped to reduce the symptom (症状) of the common cold.
If you feel the cold, you should drink something warm. Add honey and lemon to hot water or tea. You will keep warm while you're drinking tea. In traditional Chinese medicine, ginger (姜) has been used for over two thousand years. A cup of ginger tea helps to increase the blood move and make you sweat through your body.
Garlic (大蒜) is a super food. Garlic helps to fight off germs (细菌) when eaten daily. It can reduce the number of colds you get each year and shorten cold symptoms. If you don't mind eating uncooked garlic, it's best to eat a few pieces every three to four hours when you feel the first signs of a cold.
It's no secret that salt gets rid of germs. For a sore throat, mix about half a teaspoon of salt into warm water and use as a mouthwash. Whether it's for breakfast, lunch or dinner, the Japanese enjoy umeboshi, sour and salty apricots(杏子) that help keep the doctor away. Using a neti pot is an old practice from India that helps people breathe better. As a mixture of salt and water pours into the nose, the germs are cleared away.
Although cutting an onion can make you cry, it's good for a blocked nose. People in Mexico and Spain eat hot peppers to get their sense of smell back temporarily during a cold. Of course, you'd better be ready to experience a wave of heat! In Korea, kimchi is a popular side dish that keeps people healthy. It's made from pickle vegetables, red hot sauce and sometimes garlic and ginger.
It is common to have a cold, and Mother Nature’s remedies will be there for you to lower your pain when you need to fight against that cold!

Who was the most talented person that ever lived? It might be Leonardo da Vinci. The Italian was a painter, sculptor (雕塑家) and inventor. This year, we celebrated his 566th birthday on April 15th.
Da Vinci is still widely considered as one of the greatest painters. His most famous painting, the Mona Lisa which still sits in the Louvre Museum (卢浮宫), is one of the greatest art works of the world.
The Mona Lisa is famous for the mysterious(神秘的) smile. What is the reason for the woman’s smile? This is a question always asked, but it remains unanswered to this day.
Some believe that the Mona Lisa is actually a portrait (肖像) of Da Vinci himself! This is because some of her expressions on the face are similar to those in one of Da Vinci’s self-portraits. Others might suggest she smiles because she has lost her teeth! We will never know for sure… It is just fun to guess!
But the new research from scientists showed that some people even think she isn’t smiling but looks unhappy. The scientists also said that if Mona Lisa doesn’t look happy to you, it might be because of your own feelings.
The researchers showed 43 people two groups of pictures. Group One all had neutral(中性的) faces. Group Two had happy and angry faces. Each time, people saw two pictures, one from Group One, the other from Group Two. Later, they described what the neutral faces were like. When people saw a neutral face after a happy face, most of them thought it was smiling. When they saw a neutral face after a sad face, most of them thought it had a sad expression. Scientists believe our brain has predictive (预测性的) power. People use their past experiences to predict what they are going to experience next.
“________” said Erika Siegel, one of the researchers. “However, if you see the Mona Lisa after you have great fun, you can see her beautiful smile.”

But there are a few exceptions, primarily among mammals (哺乳动物) that live in close social groups. Canadian zoologist Anne Innis Dagg described groups of langur monkeys in India in which older females lived with their daughters and grandchildren. The grandmother langurs have a particular job: they protect the group's babies against hurt from humans, dogs and other monkeys. Some female langurs even give their own grandchildren special treatment, cleaning their fur and stepping in when they play too roughly with other young.
Many whale species, too, travel with their families,including both grandmothers and grandcalves. In groups of sperm whales, according to Dagg, old females help babysit the group's young while their mothers dive (潜水) for food. Orca grandmothers often lead their family members and can live for many years after they stop reproducing. In 2015, scientists suggested that these elder orcas help their grandcalves through hard times, because they remember all the best places to find food.
Female elephants rule the whole family. Calves (幼崽) are typically born into groups led by their grandmothers, who can live to around 80 years old. The female elephants form close relationships, said Lahdenperä, and raise their young together. Lahdenperä found that the calves of young mothers were eight times more likely to survive if their grandmothers lived near them than if they didn't. When the calves' mothers were older and more experienced at raising babies, this beneficial “grandmother effect” disappeared even if the actual grandmothers were still around.
It isn't very clear how elephant grandmothers help their inexperienced daughters, said Lahdenperä. It is believed that they may help nurse their grandcalves. But Lahdenperä thinks that the more likely advantage is the wisdom a grandmother elephant has got during her long lifetime.
And what about grandfathers? Studies of humans in recent years have shown that a living grandfather can improve a person's mental health and well⁃being, said Lahdenperä.
But there are signs of that in the animal kingdom, she said. Male animals seldom socialize with their own children, let alone grandchildren. “Males are usually focusing on producing their own children and aren't providing so much care,” Lahdenperä said.
