Four years ago， Chinese skater Wu Dajing introduced himself to the skating world by winning a silver medal at the Sochi Olympic Winter Games． At this year's Pyeong Chang Olympics， Wu not only returned， but also made history．
On Feb 22th， 2018， Wu won the gold medal in the men's short﹣track 500﹣meter race． He set a new world record with a time of 39.584 seconds． He also became the first Chinese man to take home an Olympic short﹣track gold medal． BBC said Wu's win was "flawless"， because he was much faster than all of the other skaters．
"I didn't give them a chance and I kept my speed from the start，" he told the reporter after the match．
But China's short﹣track teams didn't do well in general at the Games． Chinese skaters in the women's 500meters， 3000﹣meter relay and men's 1500 meters all failed to take home the gold． Wu was China's biggest hope， which put a lot of pressure on him． But he proved himself with his great performance．
Wu is now known as a highly talented skater． But things were not always that way． When Wu joined the national team in 2010， he was seen as almost "nothing" compared to gifted skaters like Zhou Yang and Fan Kexin， as his coaches said at the time． Their words made him quite upset． But Wu didn't want to give up and worked as hard as he could． He practiced skating all year round． He even didn't return to his hometown for the holidays for 10 years． "I believe in myself，" he told the reporter after his match at the Olympics．

Humans have five senses：sight，hearing，smell，taste and touch．They collect information for the brain．For example，the eyes collect information on pictures and the ears collect information on sounds．
Sometimes a person loses a sense．Their other senses become better．For example，a blind person has much better senses of hearing and touch．
Sight
The eyes can only see with light．Light carries the picture of something into the eyes so humans can see it．But do you know that the picture is upside down？The brain has to turn the picture the right way up again．
Hearing
Sounds travel through the air like waves （波）．Human ears are like cups．They catch sound waves for the brain and the brain translates them as different sounds．
Smell
Humans smell with their noses．Most people can recognize about 10，000 kinds of smell．This is amazing!Humans each have five million receptor cells （感受细胞）in their noses．Noses are not only for smelling．They also clean and warm the ail that people breathe in．How does the nose prevent the dirty air from getting into the body？Well，it sneezes（打喷嚏）！
Touch
There are receptor cells for the sense of touch all over the body．This is different from the other senses．Touch receptor cells are in the lowest part of the skin．They help the body to have all kinds of feelings like pain，cold and heat．Some parts of the body （like the finger） are more sensitive（敏感的）than other parts of the body （like the back） because they have more touch receptor cells．
Taste
People can taste food because they have about 10，000 taste buds（味蕾）on their tongues．Old taste buds die and new ones come out every two weeks．But when people get older，this happens less often．That's why old people often complain their food is tasteless．Scientists also find that smokers have fewer taste buds．Do you want food to taste good？Well，don't smoke!
For hundreds of years，people knew the basic tastes were sour，sweet，salty and bitter（苦）．In 2002，a fifth taste，umami（delicious taste） joined the list．Now，a study from Purdue University in the US found that fat could actually be the sixth basic taste．
To be considered a basic one，a taste needs to beable to active certain receptor cells in the mouths．A study has shown that humans have fat receptors in the mouths．Not long after that，a scientist made a study to test a second question：can people taste the difference between fat and other tastes？
Richard Mattes gave the testers six different kinds of things．Each kind had a taste：sweet，salty，sour，bitter，umami or the newcomer﹣fat．Mattes asked the people to pick out tastes by their differences．This was to test whether or not fat would be picked out from the group．Most of tlie testers could clearly find out the different taste of fat．
Then how does fat taste？"It's terrible．"Mattes said．"However，the taste can be pleasant in a small amount，just as we enjoy the bitterness of chocolate．"

Smashed cucumber （拍黄瓜）salad is one of the most popular cold dishes in China．You can find the green dish anywhere from restaurants to homes．（1）
According to The New York Times，smashed cucumber salad is"everywhere"in New York．Some restaurants have even added the dish to their menus．（2） But American cooks are trying yogurt，honey，lemon and other common western ingredients．
Why is this dish becoming so popular？（3） Smashed cucumbers can hold onto tastes more than cucumbers which are cut into fixed shape and size．"Just changing the way you break down an ingredient…changes the way it feels and tastes．It's cool．"said Danny Bowien，a cook at a New York restaurant．
（4） The cook smashes fresh cucumbers with the flat side of a knife．（5） Then other ingredients can be added．Also，it takes only five minutes to make the salad．Cook Julia Goldberg said it's really"satisfying"．

Dear Merry，
Recently，I have trouble with my study．
In school I can't listen to teachers carefully because I always feel tired and sleepy．I don't spend time with friends after class either because I think it's a waste of time．I even miss writing some answers in the test．
At home，I can't get my homework done every night．My parents don't let me stay up．So
I have to get up early the next morning to finish it．Lately，I even get a bad headache．
How can I solve these problems？
Yours，
LiuYa
Dear Liu Ya，
When you have trouble listening to teachers carefully in class， you can ask your teachers or deskmate to remind you often．Then spending time talking about many different things with friends can make you happy．It's not a waste of time．As for homework，when it's hard to get finished，one thing you can try is setting goals for yourself．Ask your parents to help you．You must take a break，especially if you don't feel well．You might be surprised but a short break can help you get more done!Lastly，if you don't worry and have enough sleep，your headache will leave you．
Yours，
Merry
