This month, we went on a five day trip to Xishuangbanna, a beautiful place in the south of Yunnan Province. The weather there is hot and wet. There a {#blank#}1{#/blank#} many kinds of plants and animals. I want to i {#blank#}2{#/blank#} some interesting things we saw to you during our trip.

In the jungle(丛林), we saw a twining(缠绕的)plant. These P {#blank#}3{#/blank#} grow when seeds-seeds mainly from banyan tees (榕树)are moved by animals or wind to some other trees. These seeds gradually grow, developing their own aerial (空气的) roots. Little by lite, they will get themselves around the host tree and f {#blank#}4{#/blank#} kill it, just like a snake kills its enemy.

A {#blank#}5{#/blank#} thing we learned is that when a tree gets big and strong, some of its aerial roots will grow into the ground and develop into a new tee, just like the way cell division (细胞分裂) works. The w {#blank#}6{#/blank#} tree will look like a small forest. I think this is quite a {#blank#}7{#/blank#}.

In the forest, you will sometimes find some red leaves among the green leaves. Why is that?

One reason is that the sunshine is very strong in Yunnan. The trees n {#blank#}8{#/blank#} use all of their leaves in order to do photosynthesis (光合作用) and grow, so the color of some of the leaves c {#blank#}9{#/blank#}to red.

We really enjoyed our trip to Yunnan. We learned a lot about n {#blank#}10{#/blank#} and had a rally fun time. I hope we can take more trips like this in the future.

I saved the grain carefully and finally had enough to plant. I built a wall around my garden to keep the wild goats away. Then I killed some birds and hung them among the crop to stop others getting closer.

With my new grain to store, I found a new problem. The fine grain ran through my baskets. It took me nearly two months to form and dry two ugly pots—one for rice and one for wheat.

Next I formed a clay oven and made some other tools from hard wood and cloth to bake bread. I made and baked bread in my oven. I spent the third year on the island in farming and baking.

Soon after that, I began to think of my days sailing in a tidy boat with Xury. I wished to have a boat and explore the island by sea.

I tried to turn over the ship's boat that I had seen washed up, but failed. I still decided to have a boat. So I chose a strong tree and spent weeks cutting it down. Then it took me months to turn it from tree to boat.

When it was time to set off, I realized I had made my boat too far from the nearest stream. The boat was far too heavy for me to move. I tried bringing the water to the boat instead of the boat to the water. I soon saw it would take me twenty years of constant labor.

I celebrated my fourth year on the island with two boats, but I was no closer to a sea journey.

For families suffering from the {#blank#}1{#/blank#}（lose） of their loved ones, grief chatbots（聊天机器人） can now help them still feel connected to the dead and find support in the digital world.

Since 2022, Super Brain, {#blank#}2{#/blank#} artificial intelligence（Al） company based in Nanjing, Jiangsu province, {#blank#}3{#/blank#}（create） digital avatars（化身） for more than 600 families.

"Technically, digital immortality（永生） is coming... which will enable everyone to have a virtual（虚拟的） online twin," said Zhang Zewei, co-founder of the Al company.

While creating digital avatars of those who have passed away, Zhang notes that the company has also helped over 100 clients（客户） in {#blank#}4{#/blank#}（make） their virtual avatars from their digital trails（痕迹） such as emails, photos and social media posts. The prices for the services can be from thousands of yuan to 10,000 yuan.

{#blank#}5{#/blank#} Zhang's clients are parents missing their only child, a woman wanting to say goodbye to her boyfriend who died in an accident, and a mother wanting to "revive（复活）" her husband to comfort their daughter.

While the idea might seem strange to some, Zhang believes that because of the emotional support the technology offers, those dealing with regret and loneliness following the loss of their loved ones {#blank#}6{#/blank#}（attract） to the technology.

However, he's still {#blank#}7{#/blank#}（sure） about how much of a connect ion that technology can offer. "A chatbot has no warmth," he argued, pointing out that these avatars cannot stay up to date with the latest information.

Tech experts and psychologists are also expressing worries. Wang Qiang, a psychologist in Beijing said that these "griefbots" could make people feel like they have a real emotional connect ion with the {#blank#}8{#/blank#}（die）. But in fact, it could make people feel emotionally and mentally {#blank#}9{#/blank#}（bad）, making it {#blank#}10{#/blank#}（challenge） for them to move on.

Li Bai did not like studying when he was a child. Besides, he was very naughty (顽皮的). One day, the teacher was not in the classroom, and students were all reading books by themselves. However, little Li Bai quietly went out to play.

Little Li Bai came to the river at the foot of a mountain. Then he saw an elderly woman grinding (磨) an iron rod (铁杵) on the stone. Little Li Bai was surprised and asked, "Lady, what are you doing?" The elderly woman answered, "I am grinding the iron rod into a needle (针)." Little Li Bai was surprised and asked, "Oh! It is so thick (粗). How can it be a needle?" The elderly woman answered, "As long as every day I grind the rod a little more, it will be thinner and finally become a needle." "It is so hard for you to make it," said little Li Bai. "But I will keep on doing it day by day. Nothing is impossible," said the elderly woman.

Hearing it, Li Bai turned around and ran back to the classroom. From then on, he kept studying hard every day and became a talented poet (诗人) later.

Hi Betty,

I'm really excited that you are coming to China next month!
