Without plants, the land can become deserts much more easily.

Students trained from 7:30 am to around 10:00 am or from 4 pm to 6:30 pm, because it was very hot this summer. They wore white hats, T-shirts and blue trousers. The hats and T-shirts were printed with a red logo, the number "60". The first week of training was PE. Students practiced standing and squatting. Then they moved on to practice the group show.

Write a multi-choice question for the following article: Article: Sing the Language You're Learning How can you remember a song from your childhood to this day? Why do your teachers use songs to teach you English? It seems there is a scientific reason for this. Researchers are now studying the relationship between music and remembering a foreign language. They find that remembering words in a song is the best way to remember even the most difficult language. "Singing could be a new way of learning a foreign language. The brain likes to remember things when they are used in a _ and meaningful way", said Dr, Karen Ludke. The findings may help those who have difficulties learning foreign languages. On his blog, Dr. Ludke writes, "A listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area." Many language teachers know the value of using music and singing. Hua Zhuying, a teacher at a Chinese language school in Washington, D.C. depends heavily on songs in teaching Chinese. She says, "I use music all the time to teach children Chinese. For little kids usually we use the music. Not only does it work, but it is fun for kids." "Sometimes, I think if I were taught English that way, maybe I could speak much better English than now," Hua Zhuying adds. Our brain likes music, especially for remembering. So, if you're still struggling in learning a language, why not try singing it out ?
