Is bicycling hard to learn? Different people     1     different answers. It is strange enough that the same person may also have     2     different answer as time goes by.

Five years ago when I was in Junior Grade One, I was interested     3     bicycling because I thought my uncle was very cool     4     he rode his bike. He could ride a bike with only one wheel. He could also sit on the bike and keep it standing straight, without moving for a long time.

I thought it was     5     to learn to ride a bike, so I decided to learn from my uncle. He told me     6     to ride. When I     7     off the bike the first time, I hurt myself. So I was afraid to try again. It was very     8     for me to learn. Then my uncle helped     9     by holding the bike and not to let go. With his     10    , I could ride. “You can do it by yourself now young boy!” I heard his voice far behind me.

My mother asked me when I was 5. “What is the most important part of the body?”

I said, “Is it our ears?” “No.” she said. “Because there are still many people who can’t h    1     things. Keep thinking and I’ll ask you again later.”

Three years passed before she asked me again. This time I said, “Sight is important, so it must be our e    2    .” “No,” she said. “Because there are many people who can’t see things.”

I kept this q    3     in my mind. My mom asked me a couple more times and the o    4     reply I got was, “You are getting closer to the answer.”

Last year Grandpa passed away. Everybody was quite s    5    . When it was our turn to say goodbye to Grandpa, Mom asked me, “Have you thought out the most important part of the body?”

I was so s    6     when she asked me this. She asked me such a question at this moment! “This question is very important. How you answer it shows whether you have learned about life. T    7     is the day you need to learn this lesson.”

She looked at me the way only a mother can. I saw tears (眼泪) in her eyes. She said, “My dear, the most important part of the body is your shoulder (肩膀). ”

“Is it b    8     it holds up your head?”

“No.” she replied. “It is because it can hold up the head of a friend or loved one when they cry. Everybody needs a shoulder to cry on. I only hope you have e    9     love and friends anytime you will have a shoulder to cry on when you need it. And I hope you can be the shoulder for someone when you are needed.”

At that moment, I seemed to understand the true meaning of l    10    .

【推荐3】It was a fine day. The sun was shining and the wind was gentle.

The kids were playing in their backyard when a little cat tried to cross into their yard. U    1    , it got stuck under the fence. The kids tried to free the cat, but they couldn’t , so they a    2     their mother for help. The cat looked so cute that the children begged to keep it. Their mother said, “I s    3     we can. I don’t mind myself, but you must ask your father too.”

The kids waited anxiously for their dad back from work. “Do you think our dad will a    4     us to keep it?” the girl asked. Before the boy answered the girl, they heard their father opening the door. “Hi, Daddy,” they both shouted loudly at the same time.

“You are surely happier than u    5     to see me today. What is up?” their father said.

“Nothing, Daddy. We just love you so much,” the girl replied. That’s when their mother said, “Go ahead. Ask your dad.”

The girl told her dad what had happened and asked to keep the cat. The father said, “No, you can’t. We have fed five cats so far. Your mommy and I have no time to take c    6     of any more.” H    7     this, the kids lowered their heads disappointedly.

Seeing the sad looks on the kids’ faces, the father changed his m    8    . He said, “All right. Since you love it so much, you can keep it.” The kids happily screamed “Hooray! Thank you, Daddy!” However, the father added that they must p    9     to look after the cat by themselves.

The kids were so happy to have another pet friend. Then the cat was g    10     the name “Lucky” by the kids.

So the cat had a place to call home.

People often use their phones to take pictures of their fantastic meals to share online. But Clear Plate, a Wechat mini-program, makes you take an active part in saving food by taking pictures of your empty(空的) plates after a     1    . The program’s AI “sees” that your plates are empty and gives you points. You can use them to buy “gifts” for     2     or others. For example, to buy some food for children in poor villages is what most users do with such points.

In 2017, Liu Jichen, 23, a student at Tsinghua University,     3     the program and bettered it with his group. Firstly, they tried very     4     to teach the program’s AI how to recognize(分辨) empty plates, which took half a year to collect(收集) 100,000 photo samples(样本) from cafeterias and restaurants in 10 cities. In 2018, they also held an activity called Clear Your Plate in Chinese universities. Students had a competition to see who could get those     5     points in Clear Plate.
