Whether (无论) you are a dog person or a cat person, did you notice how different dogs look compared with cats?
Cats have different sizes, different colors, different fur patterns, and different head shapes. However, they still all look like members of the same kind.
There are fewer differences among cats compared with dogs. Corgis are short-legged, with long and strong bodies. Greyhounds are tall, thin and fit, and leggy. Mastiffs are short-haired fighters that can weigh over 45 kilograms.
Why are there such huge differences among dogs? And why are cats so much more similar? Well, it's all because of their jobs.
Both cats and dogs began living with humans long before there were different breeds (品种). Historical records show that dog domestication (驯化) first appeared about 15,000 years ago. And cats' domestication happened about 10,000 years ago.
As time went on, people realized that dogs could do different jobs. For certain needs, people began shaping dogs differently. They picked two dogs with the traits (特点) they loved and let them "start a family." Over generations (代), these chosen traits became stronger. For example, herding goats (放牧山羊) in mountain areas needed a different type of dog from herding sheep on farms.
Cats, however, did a perfect job in their shapes and sizes. So their owners didn't need to change them too much.

How much do you know about whales, a kind of fantastic animals? They are huge, beautiful, and interesting animals on Earth. Are they fish? Although they look like fish and their homes are in the sea, in fact, they aren't fish. Let's learn more about them.
It's amazing to think how big whales are. Blue whales are the largest among all kinds of whales. They are also the biggest animals on Earth. Some of them are more than 33 meters long, and each of them weighs about 150 - 180 tons. A blue whale is even heavier than 24 elephants. A new baby blue whale weighs as much as a big elephant. The blue whale also has the largest heart in the world. It can be as heavy as 180 kg. Whales feed on sea life. Some whales eat seals and fish. Another interesting fact is that whales must come to the surface of the water to take in air. So they often jump out of the water.
Though whales need to take in air, they can't stay on beaches for a long time. Beaches are not safe places for them. They need to stay in the sea. For whales, the mistake of landing on beaches is dangerous. They may lose their lives.
Some kinds of whales are in danger because people catch them for meat, fat, and oil. Whale parts are sold to make things like candles and soap. We should try our best to protect whales. Stopping the killing of whales and fighting ocean pollution are two useful ways to protect them. When you see a whale on the beach, try to save it.
