Alicia Waters Galan is litter-picking all the way from her home in Spain to Paris. She is heading to Change NOW 2024, an event where people will come together to discuss _________ about climate change and try to find ways to solve them.

Alicia decided to _________ after visiting an aquarium (水族馆). There she learned that some _________ which are discovered in the oceans often ate plastic and some even died _________ plastic bags. It made her feel angry and _________, so she made up her mind to do something to help them.

When she picks up litter on the street, she sometimes does get some funny looks, but she doesn’t _________. She said, “Even if some people might wonder what I’m doing, I’m sure they will understand it and do the same thing themselves one day. ”

Her _________ for other young people who are interested in litter-picking is, “Wear gloves, bring a litter picker, go with an adult and don’t pick up anything sharp.”

When it comes to _________ environmental work with schoolwork, Alicia says, “Yes, I’m a volunteer, but I’m also a 10-year-old girl. School first, then pick up the litter.”

By sharing her environmental work with her teachers and classmates, Alicia is _________ others to join in. Now her classmates always volunteer to clean the school __________ and they even go out to clean our beaches, parks and streets on weekends.

Let’s learn from Alicia and start to help by picking up any litter you see on the ground.

Three young people told us their ideas about visiting museums.

I can still remember the day when Mr. Pearson asked me to wait after class for a “quick talk”. He was my science teacher. Although I had always been good at science, I had given up a bit with schoolwork by Grade 8. So that afternoon, Mr. Pearson sat down next to me and asked me what I wanted to do with the rest of my life. I told him I wanted to fix cars because I loved cars.

“What about making them?” he said.

“Making them?” I asked. “Like in a factory, do you mean?”

“No.” said Mr. Pearson. “I mean being an engineer and getting proper training to design cars-the best cars in the world possibly.”

“That sounds pretty cool,” I said. It was something I’d never thought I might be able to do.

“Well,” said Mr. Pearson, “I know that you are good enough at science to do that. But at the moment, you’re not really trying.”

“I just...find everything a bit boring,” I said.

“It is sometimes boring when you’re in Grade 8,” said Mr. Pearson. “But it’s like climbing a mountain. You can’t get up to the top until you’ve worked your way up from the bottom. It’s hard sometimes. The path is steep (陡的), and there’s no view. But get yourself up to the top, and you’ll see the most amazing views.”

Mr. Pearson was there for me after that, to explain things and help me with any problems.

And every month or two, he asked me, “How are things on that mountain?” “No views yet,” I always said, “but I’m still going up.”

Mr. Pearson was right about the mountain. At last, I was interested in science and was really excellent at it.

You see advertisements (ads) every day. Ads try to persuade (说服) you to buy things or tell people about coming events for you to take part in.

How to write an ad? Before you write an ad von need to know your readers. What group people are you trying to reach?

Writing an outline (提纲) can make sure you include all the important information. Imagine your school is having a fair to raise money for a new playground. You want as many students as possible to come. Use words that will draw people’s attention. Keeping your sentences short will help your readers read your ad more quickly. You can make an outline like this:

Now you have decided which words to use in your ad, you also need to choose a design (设 计) that will make your ad persuasive. Bold (加粗) letters and bright colors get people’s attention. Picking the right picture to appear on the ad is an important step. Don’t try to fit too many words and pictures into your ad. Try different styles until you work out which one is the best. Then do the final draft of your ad and bring the words and the design together! Look! What a good example it is!

Keep reading ads and practicing writing your own ads until you can be a good writer of ads!

Imagine you’re in a sci-fi (科幻小说) world, and you video-call your friend. You might see them in a three-dimensional (3D) way or in holograms (全息影像). Although this isn’t possible in real life yet, researchers recently made holograms easier to create, said a new study.

To take a 3D photo of a person, most hologram technologies need special cameras. They record how the person looks from different angles (角度) under different lights. This information makes the hologram look lifelike. However, holograms can’t be widely used because they are difficult to make.

The researchers from Chiba University made a new computer program. It can turn normal pictures we take into 3D holograms.

Their program uses a technology called deep neural networks (神经网络). First, it receives information from a picture taken by a normal camera. It then guesses the depth of things in the image. With all the information, the program creates a 3D hologram.

In the future, when holograms become more common, they can help more people. Medical students can learn quickly by looking at 3D pictures of the human body.

But some people don’t like this idea. They think that problems will happen if people use the technology too often. They might not go out to meet friends because they can see their friends and watch a movie at home with friends, even if they live in another country.
