The train wasn't overcrowded when I was ...

    During the long holiday, did you feel bored and decided to check social media, only to find that your best friend was at the beach, that your classmate was going hiking, and that your cousin or niece was enjoying a feast? Have you got the feeling that others are experiencing things and enjoying life more than you are？

Oh, you might feel that you are missing out. 1. FOMO is the anxiety caused by a nagging （难以摆脱的） feeling that you are not taking part in the exciting and worthwhile things going on around you．

As is known, comparison is the thief of joy. FOMO makes us check social media more frequently, leading to an addiction and a negative cycle that is hard to break．2. These include the feelings of depression, loneliness and boredom．

3. You can avoid FOMO by focusing on being mindful, changing your habits, and working to be more grateful for your own life．

Social media is often what contributes to FOMO more than anything else.If you are feeling very upset when seeing all of the fun that others are having,take a break from your accounts.In this case,you'd better stop looking to social media for happiness.4.

Besides, one of the best ways to overcome FOMO is to begin to truly appreciate what you value in your life. Make a list of all the things that are important to you, including subjects, people, dreams, possessions or experiences．5. You will find the true value of your life．

Do remember that if you miss an opportunity, other opportunities will come．

A． Have you ever experienced FOMO？

B． What can you do to overcome FOMO？

C． Spend some time reflecting on these things．

D． You can permanently do so if you feel it helps．

E． The feeling is called the fear of missing out or FOMO for short．

F． Researchers have found that FOMO can cause serious negative results．

G． If it controls you, the only thing you really miss out on is your own life．

    Scientists think they have the answer to a puzzle that confused even Charles Darwin： How flowers evolved and spread to become the most important plants on earth．

Flowering plants, or angiosperms (被子植物), make up about 90% of all living plant species,but how they did this has been a mystery. New research suggests it is due to genome (基因组) size．

Hundreds of millions of years ago,the earth was dominated by ferns (蕨类)and conifers(针叶树) - they were the main plants on the earth． Then, about 150 million years ago， the first flowering plants appeared on earth. They quickly spread to all parts of the world．

Why angiosperms were successful and diverse on earth has been debated for centuries.Charles Darwin himself called it a "mystery", fearing this apparent sudden change might challenge his theory of evolution．

Kevin Simonin from San Francisco State University in California US and other researchers analyzed data held by the Royal Botanic Gardens, Kew， on the genome size of hundreds of plants, including flowering plants, gymnosperms (a group of plants including conifers) and ferns. They then compared genome size with anatomical (结构上的) features. This provides "strong evidence" that the success and rapid spread of flowering plants around the world is due to "genome downsizing"．

By reducing the size of the genome, which is contained within the nucleus (核) of the cell, plants can build smaller cells. The researchers say genome-downsizing happened only in the angiosperms, and this was "a necessary condition for rapid growth rates among land plants"．

    The development of a V-shaped fuel-efficient airplane design known as the Flying-V will be funded by Dutch national carrier KLM Royal Dutch Airlines．

To improve the sustainability （持续性） of air travel, the Flying-V was developed by researchers at Delft University of Technology in the Netherlands, also known as TU Delft．

Its futuristic design puts the passenger cabin into the wings. It's said the plane will use 20% less fuel than the Airbus A350-9-while carrying a similar number of passengers．

"In recent years, KLM has developed as a pioneer in sustainability within its airline industry," said Pieter Elbers, CEO and president of KLM. "We are proud of our progressive relationship with TU Delft"．

"Air travel is contributing about 2.5% of global CO₂ emissions (排放物)， and the industry is still growing, so we really need to look at more sustainable airplanes," said TU Delft project leader Roelof Vos．

"We cannot electrify planes, as electrified airplanes become way too heavy and you can't fly people across the Atlantic on electric airplanes- not now, not in 30 years," Vos said. "So we have to come up with new technologies that reduce fuel burning in a different way."

"We've been flying traditional airplanes for decades now, but it seems like they are reaching the limit in terms of energy efficiency," he said."The new design actively contributes to the lift of the airplane, and creates less air drag."

The plane's increased fuel efficiency is largely a result of its design, Vos explained．

The researchers hope to fly a model this September, Vos said, while the new cabin design will be open to the public at Amsterdam Airport Schiphol in October. The completed plane is expected to enter service between 2040 and 2050．

    Growing up in England with a British father and a Chinese mother, I've enjoyed food from both countries ever since I was able to hold a knife and fork and chopsticks!

Mum has sweet memories of the food from her home town in Sichuan, and often cooks spicy dishes.Thanks to this， Dad has come to love hot pot! But there are still some dishes that Dad dare not try even after many years of marriage to my mother. Even today he still does not take to eating things like chicken feet．

But I enjoy that sort of food myself. Last week, I went to the butcher's and asked, "Do you have pigs' ears？" "No," the butcher said, pulling at his own ears, "just these ordinary ones." He must have thought I was joking．

Dad can cook a super "full English breakfast" of bacon, eggs, beans, sausages and toast with butter. Mum and I just have to find a way to get him into the kitchen! He also does a typical Sunday roast.We all love roast beef and vegetables．

I'll never forget my first visit to China. Mum encouraged me to try different kinds of food. But just when I thought I could deal with all Chinese food, I came across stinky tofu, a horrible grey thing that looked and smelt like a burnt sports shoe. I gathered all my courage to take a bite and was amazed to find it wasn't so bad. It reminded me of blue cheese, a similarly strong smelling type of food you either love or hate. Maybe I'll fall in love with stinky tofu, someday.

People say that one man's meat is another man's poison, but I feel at home with food from both my cultures．

Lu You： chosho

As a noted productive poet， Lu You from the Song Dynasty wrote more than 20，000 poems in his lifetime． According to historical records， he lived to 85 years old， the longest living poet in the Song Dynasty．

However， Lu You was weak as a child． During his later years， Lu You started the body building called chosho． Chosho was quite popular in ancient times， which was not roaring or whistling， but an elegant， serious and skillful health method． People opened their body， breathed in deep and then breathed out with a long and loud cry in rhyme．

Su Dongpo： long run， five kilometers per day

The great Song Dynasty poet Su Dongpo， or Su Shi preferred to take long runs， and he thought that only by moving your body regularly could you have a strong body．

He would slow down when he breathed hard， and speed up when his breath balanced． Su Dongpo would run until he was sweaty， hot， blood circulating and limbs feeling refreshed．

Huyan Zan： cold bath

There was an annual festival in November during the early Tang Dynasty （618-907）called "Pouring cold"， where a group of strong men， nearly bare， sang and danced in the street while crowds poured cold water on them． The festival， a sacrifice to god， was thought to be helpful to body building．
