—It means the lowest part of something.

    There are more than 20,000 kinds of fish. Which fish swims the fastest? Where are seahorses from? Read on to find out!

    Who is the fastest? It is the sailfish (旗鱼). Its bill (嘴) is long and thin. Its fin is like a big sail (帆). These things help it swim fast. It can swim 100 km an hour. That is as fast as a car on the highway.

    Seahorse is a fish! And it is a very different kind of fish. Father seahorses give birth to (生产) baby seahorses. It has a pouch (育儿袋), and the mother seahorse lays eggs in it. The pouch can carry 2,000 babies at a time.

    Do you know flat (扁平的) fish? Its eyes are on one side of its head. It is a flounder (比目鱼). When flounders are newborns, their two eyes are on different sides of their head. After about 20 days, one eye moves to the other side.

    Do you know whose job is to stop food from going from one country to another? B-E-A-G-L-E-S! Do you know why? Because these dogs love food. They are perfect for the job.

    Beagles work at airports in a lot of countries, such as Canada, the United States, Australia and New Zealand. Their job is to sniff (嗅) out food. These special dogs have special noses. They can even smell food in bags or boxes. When a dog finds a bag with food inside, it sits in front of the bag. If the dog finds the food, the workers will give them something good to eat.

    These dogs don't live in a house because the food in houses distracts (干扰) them. Their noses are very important. Living away from people helps to protect their noses.

    These working dogs should not be afraid of large groups of people or other dogs. They should not be afraid of loud noises. They should feel well when travelling in a car.

    Next time when you're at an airport and see police dogs, don't play with then. They are busy. They're working to keep us safe.

    Dogs can be good friends for people. They can also be in !

    Well, the US held the 140th Westminster Kennel Club Dog Show (威斯敏斯特全犬种大赛) in New York City. This is sporting event in the US.

    To take part in this show, a dog must be 100 percent one kind of breed (品种) .

    On the day of the show, owners to make their dogs look good. Then, they show their dogs to the audience (观众) and judges (裁判) . Judges are : how dogs act, their fur (毛发) and more.

    To be in dog shows like this, it costs around $50,000 to $100,000a year. So why do people do it?

    Some do it to teach people about dog breeds, while others want . But they must love their dogs a lot because they spend so much time and money on them.

    Many animals around us are smart. Let's get to know some of them.

    Dolphins are smart animals in the sea. Researchers put sea animals to a test. Many sea animals either ran away or fought with the ones in the mirror. However, when the dolphins saw themselves in the mirror, they tried to clean the red marks off their bodies.

    Bees work hard, and they are smart enough to learn something. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. Instead, when the researchers showed them vertical lines (垂直线) , the bees simply flew away, because they knew there was no way to get sugar.

    Chimpanzees (黑猩猩) are very human-like. Researchers showed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing.
