Do grown-ups still grow? Well, some parts of a grown-up's body do not grow, but some do.

Grown-ups cannot get taller. The bones (骨骼) of their arms, legs and neck lose the ability to get longer. After the age of 30, people start to become a little bit shorter. They will have lost about two and a half centimeters of height by the age of 55. 

Meter your height when you get out of bed in the morning and then again before you go to bed that night. You will be a little bit shorter at night because during the day, your cartilage has got pressed together. When you sleep, the cartilage opens up, and you are taller again in the morning.

Grown-ups can grow bigger muscles (肌肉) if they exercise and if they eat healthy food. Riding a bicycle or running a lot will make leg muscles bigger.  It's best to do some exercise for all the muscles.

 This is also a kind of growth, but not a healthy one. The best way to grow healthily is to exercise often and eat a lot of different healthy foods.

You should do some exercise to keep . /ˈhelθɪ/

Yuan Longping, known as the "father of hybrid rice(杂交水稻)", once said he had two dreams. One was "he could e the cool under the rice taller than men" and the other was "hybrid rice would be grown all a the world".

Now, his first dream has been realized. China has s cultivated(培育) the "giant rice". It has grown to over two meters. It was planted in Chongqing's Changhong village in April, 2021.

The h of each rice plant is between 1.8 meters and 2.25 meters, much taller than the c one. And the yield(产量) per mu may r 750 - 900 kg. This type of rice has strong and tall rice stalks(茎), and it can be planted in different environments. What's more, the place where the giant rice grows has enough water, so farmers can also f fishes and shrimps there. From next year, t of mu of fields will plant this kind of rice in Chongqing.

After r the news, Chinese people c it a "dream come true" moment for Yuan Longping. Many people posted online to pay their respects to Yuan and said, "Your dream has come true. Can you see it?"

As a famous piano master, Paderewski was admired by many people. Wishing to make progress on the piano, one day, a boy to a Paderewski's concert by his mother. After they were seated, the mother saw a friend and walked up to greet her, leaving the boy alone in seat.

Catching the chance to explore the wonders of the concert hall, the little boy stood up and finally made his way through a door was marked "No Admittance (进入)". Soon, the hall got dark and the concert was about to begin. When the mother to her seat, she discovered that the child was missing.

Suddenly, the lights focused on the piano on the stage. In surprise, the mother found her little boy sitting at the piano. knowing where he was, the boy was picking out Twinkle, Twinkle, Little Star.

At that moment, the great piano master appeared, moved to the piano , and whispered (耳语) in the boy's ear, "Don't stop. Keep playing." Then he sat down and added a running obbligato (伴奏). Together, the old master and the young beginner changed an embarrassing situation into a wonderfully creative experience. It became one of the  parts of the whole concert that evening. The people were touched so much by the master and the mother was shocked. She believed that such an experience would make a big to her boy's life.

In fact, that's the way it is in life. What we can do on our own is hardly unusual. We tried our best, but the aren't exactly smooth music like what we have expected. But when we trust in the hands of a greater power, our life's work can be truly beautiful.

Next time you set out great works, listen carefully. You can hear the voice of the master, whispering in your ear, "Don't stop. Keep playing."
