When I graduated from university, I decided to make my life a difference. I became a volunteer_______and was sent to Ghana (加纳). So,_________a group of helpful young volunteers, I went on my journey. I was very_______this great chance.

The schools there were quite poor. The students had to walk miles to_______their schools. They had lots of work at home. Though they had_______days, these children were joyful.

This was my_________time living abroad in a different culture. I had to get used to the_______conditions. There was no electricity, running water, phone or the Internet. There was no air-conditioner (空调) at a place where the_______often goes over 38°C! It was too hot to move. Before coming here, I_______thought I could live in such an environment. However, I could end each day with a beautiful African sunset. At night, I could________the whole Milky Way (银河).

That is my experience which is unforgetable and worth the time and energy!

One day, Tom was walking home when he suddenly noticed a young man sitting on the bridge railing (栏杆). He was going to jump into the river to kill himself.

“Hey, young! What are you doing? Are you going to jump? ” Tom asked.

“    ▲   ” the young man answered. His voice had pain in it, but Tom could tell he didn’t really want to do this. Tom tried to draw his attention. “You have any kids?” Then, the young man pulled up a picture of his daughter on his mobile phone.

“Try to think how your daughter will live on without her dad at a young age.” Tom said. His heart was beating fast, but he stayed calm. By doing so, Tom learned about the young man’s trouble.

“I am having a hard time,” the young man said. “I can’t make any money, I am hungry. And I can’t live without heroin(海洛因).”By this time, Tom had walked closer to him. He made the young man believe that he cared if he jumped into the river. Finally, the young man turned, took Tom’s hand and climbed down.

Soon, the police drove the young man away. Tom has never got his name. But he always remembers the last words the young man said to him. “Thank you ! And you really are a hero to me.”

Alex is reading a book about AI, artificial intelligence(人工智能) . He finds the book a little difficult but very interesting. Though the word AI is very popular now, he enjoys reading it very much. He has learned a new idea about AI from the book.

When people ask AI a question,, it answers the question in a very short time. So people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen. Actually, AI only uses a lot of information to get the best answer. So when it has more information, the answer will be much closer to the perfect one. AI technologies will be clever tools for human beings to use. This book also says almost half of our jobs will be done by AI technologies in the near future. People will soon find more AI technologies in our lives, such as checking the tickets, the price, people’s faces and fingers.

So, we believe that we will have much happier lives with these AI technologies around us.
