Let me tell you something about sharks. Sharks are among the oldest animals in the world. There are about three hundred different kinds of sharks in the world. Most sharks are about two meters long and live in the ocean.
Sharks can smell something in the water, for example, the blood of animals. That helps them find their food. Sharks mainly eat fish, other sharks and plants in the ocean.
Most sharks bite (咬) people by mistake. They think a person is a large sea animal. When the sun goes down or comes up, sharks are looking for food. So at these times people shouldn’t go swimming in the ocean.
Today people kill sharks for food and their skins. The number of sharks in the world is dropping fast.

On November 8, a huge new airship called Pathfinder 1 made its first test flights in California. It was built by a company that wants to bring back an old form of transportation. Pathfinder 1 is really big. It’s 400 feet (121.9 meters) long, which is longer than a football field. It’s the largest airship since the 1930s. But Pathfinder 1 is new and uses new ideas and materials.
Airships were popular in the early 1900s. They were used for travel and even in wars. But most people stopped using them in 1937 when an airship called the Hindenburg caught fire and burned. After that, planes became more popular.
Now, the company which built Pathfinder 1 is trying to change that. They’ve been working on Pathfinder 1 for 10 years. It looks like the old airships, but it’s completely new. Pathfinder I uses helium gas to fly, which is lighter than air and doesn’t burn. (Hydrogen gas
, which does burn, was responsible for the Hindenburg accident.) It also has 12 electric motors that can be powered by batteries. This makes it possible for the airship to take off and land without a runway.
Pathfinder 1 can fly at speeds of up to 120 kph. It can carry about 4 tons of people and things. In the future, the company hopes to show that airships can be a low-pollution way to move cargo over long distances.
