Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plane. So airlines offer passengers food. But it is common that they feel bad about the food taste. Do you agree? To solve this problem, airlines try hard to improve their food. They would like to do so because they don’t want to lose customers.
However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude(海拔)we cannot taste things as well as we do on the ground.
Also scientists have found that our noses become very dry even before a plane takes off.
As the plane moves up, the change in air pressure reduces one third of the sensibility(感觉)of our taste buds(味蕾). So our taste buds become senseless. The sad fact, however, is that our noses don’t know it.
All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy(辛辣的)food. Without doing so, the food would be tasteless.
Now there are many studies on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste.
Though scientists try their best, it is not as easy as they thought. Because they can’t deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them.

Have you ever been to the Dead Sea, one of the most famous natural wonders in the world? Have you ever considered why it is called Dead Sea? Does it hold life? Can people swim there? With all these questions in your mind, let’s know something about it!
The Dead Sea is actually a lake in the Middle East. At four hundred meters below sea level, it’s the lowest point on the surface (表面) of the earth. It lies between the borders (边界), Israel, and the West Bank. It’s about 80 kilometers wide at its widest point (包围) by hot, dry desert (沙漠).
Since it’s in a hot desert, water evaporates (蒸发) faster than the lake is refilled. And the area is lower than all the land around, it can only evaporate. And that’s what happens—water continually evaporate. In fact so much water is evaporating from the Dead Sea, it often looks like there’s a cloud of fog hanging over the lake. Anyway, it leaves behind the salt and minerals (矿物质). The water in the Dead Sea is almost six times saltier than ocean water!
Because the Dead Sea is so salty, almost nothing can live there, except for bacteria (细菌,菌类). Any fish or freshwater animals that gets washed into the lake dies almost immediately. And the shores are covered in thick salt crystals (结晶), so animals can’t even near the lake.
Since it’s so salty, why do people go there to cover themselves from head to toe with its mud (泥)? Actually, it is really safe for people. You can even go swimming there if you want, although it’s pretty hard to swim because all that salt makes it much easier to float (漂浮).
Want to know more about it? Just explore it yourself!

As the fight against the COVID-19 continues, traditional Chinese medicine (TCM,中医) has been widely used to treat COVID-19 patients in China. It is becoming more and more popular around the world.
With a history of more than 3000 years, Traditional Chinese Medicine has formed its own system to treat illness. Based on Chinese philosophy (哲学) , TCM looks at everything in two parts: yin and yang. It regards humans and nature as a unity (统一体) . So to keep healthy, we should follow the laws of nature. For example, it is time to sleep at 11 p.m., because yin power starts to regain (恢复) by then. If you often stay up late, your body will lose balance and catch illnesses.
Quite specially, for some health problems, TCM doctors may give you a food plan and right ways to eat. They will look at your overall health and help you regain your balance. For example, it is common to eat on the way to school, at our desk, or in front of the TV. But TCM thinks it’s wrong. Here are the correct ways: sit down to eat. While eating, turn off the TV and get away from the work desk. Do not miss any of the three meals. Also, get your body moving often, just as the saying goes, “Running water is never stale.”
Western doctors check the characteristics (特征) of your bodies, including blood pressure and body temperature and so on. They look for specific indicators (指标) of disease and give treatment. Western medicine focuses on “curing”, while TCM focuses on “conditioning”.
Li Shizhen, one of the most famous doctors in Chinese history, spent 27 years completing his great work Bencao Gangmu. His book is one of the greatest contributions (贡献) of the Chinese people to the medical science of the world.

“Do you know Macao was never my real name. I have been away for too long, mother ...”
Song of Seven Sons — Macao, was written by Wen Yiduo in 1925, is still in the hearts of Macao’s teenagers today. The Basic Law of Macao Special Administrative Region came out in 1993 and to work on Dec, 20, 1999, as Macao returned to China. From then on, it has become much easier to build a closer relationship with their motherland.
Chan U, an 18-year-old, is studying at the University of Macao. She said, “travelling to the Chinese mainland has become easier. Visits to Zhuhai have become a part of the daily life of some people.” Kun Lot U, 25, studies at the South China University of Technology. She said, “Many local people go to Zhuhai to buy vegetables as they are fresher and cheaper than those in local markets. Young people often go to Zhuhai to play jubensha, a role-playing game.”
The number of trips out of Macao in January was 2.23 million, and most of them went to the Chinese mainland. Cities like Chongqing, Changsha and Hangzhou are popular places for young people, according to Chan. Guangdong is also a good choice since the language and food are similar.
“Young people in Macao care a lot about what’s happening on the mainland,” said Kun, “Like the young people on the mainland, they also use apps from the mainland to know the hot issues (话题). They have learned many mainland Internet catchphrases (流行语). I know about the most popular ones such as ‘yyds’, and they make us understand more about people and life on the mainland.”
More than half of the people in Macao use online shopping apps from the mainland. Kun said that it’s because they can find almost everything they need at good prices on the apps. The products are first shipped to a collection station in Macao. It usually takes about three to seven days for local people to get the product. “The connection between Macao and the motherland is getting stronger and stronger,” said Chan.
