Last month I took a trip to Beijing Zoo. There are about 500 species of animals there. The tour guide said Beijing Zoo is one of the largest zoos in Asia.

About 71% of the Earth is the blue ocean. In the beautiful underwater world, all kinds of plants and animals live.

Animals are like children; they all need someone to look after them. If you buy it and bring it home, who will look after it?

A dog is a very intelligent animal; as long as you spend a little time teaching it, it can learn many things.

During last year’s summer vacation, I also went once. I saw horses, pandas, tigers, and other animals there. I especially like pandas, but unfortunately most of them were sleeping at the time.

Scientific research has found that the ocean floor looks very quiet; however, it is not completely silent. The animals on the seabed are constantly "talking"; it's just that human ears cannot hear it.

I didn't remember the author's name. The content of "New One Hundred Thousand Whys" has been updated, introducing a variety of scientific knowledge, including many areas such as the Earth, animals, plants, transportation, science and technology, society, and culture.
