I'm a piano teacher. I can feel 1 how talent and hard work affect my students.
In fact，not everybody was good at playing the piano. For example，same of my students just2 two or three months learning to play the piano well， 3 others need to learn for years and talent doesn't always bring a goad4 . When playing，the piano seems easy to a student，he or she sometimes finds it boring and them gives up. And talented students sometimes have have other things they enjoy5 so they give it up，too.
Some of my student work hard . But they still play 6 the piano beautifully. I teach them again and again，and7 practice for long. However，it just doesn't work for these students. In my eyes，it isn't necessary to do everything very well. When you really don't have any8 for something，the best way is to give up. Then you can9 what you"re truly interested in or good at，and put all your heart into it.
Both talent and hard work play important roles in 10 . If you want to do the best，you need to follow your talent and work as hard as you can. Don't give up halfway.
By 2050，nearly （将近） 70% of the world's population （人口） will live in cities. Many of them will become large cities with a population of more than 10 million.

Around the same speed （速度） it was 150 years ago，in the days of the horse and cart. But city planners are working on ways to solve （解决） the problem.
Self﹣driving cars
Robot taxis | Self﹣driving cars （无人驾驶汽车） or robot taxis will play a part. There'll be more than 30 million self﹣driving cars on the road by 2040. People don't need to drive by themselves. By 2050，there will be robot taxis in the city streets. We can call the taxis very quickly. |

I wrote a note to my parents when I was a young boy. I didn't write anything to them before. That night，I just had a strong desire （渴望） to let Mom and Dad know how much I loved them，how much they meant to me，and how thankful I was for what they gave me . Because I was too shy to tell them my feelings face to face，I wrote the note and put it on the desk in their bedroom. I imagined how they would feel after they read the note thousands of times before going to bed.
Early the next morning，I heard a soft knock at my door. As soon as I opened the door，I found my mom and dad standing outside. They kissed me and thanked me for the note. Mom said that she was thinking I was a little child，but to her surprise，I grew into a young boy unconsciously （不知不觉地）. Dad said he was happy that I could share my true feelings with them.
Seeing the smiles on their faces made me laugh happily. At the same time，I was surprised that my simple words could touch them so much. On that day，I saw my dad cry for the first time. The beautiful memory （记忆） stayed in my heart from then on.
Chinese researchers reached the top of Qomolangma on May 4，2022. They set up the world's highest automatic （自动的） weather station at an altitude （海拔） of 8，830 meters. This helps them to study the influences of climate change on the environment.

Half of the stations were set up at an altitude higher than 7，000 meters.
