Let me tell you something about sharks. Sharks are among the oldest animals in the world. There are over three hundred and fifty different kinds of sharks in the world. Most sharks are about two meters long and live in the oceans.

    A shark 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 skin. The number of sharks in the world is dropping fast.

People love walking through a giant puzzle. In a corn maze(玉米迷宫), they can follow miles of paths and run into lots of dead ends before they finally find their way out. The corn maze has been growing for almost 30 years. 

Simple corn mazes began appearing in the 1980s. In 1993, the first big corn maze created for the public to enjoy was made in Annville Pennsylvania, by Don Frantz and Adrian Fischer. Then, in a corntield as big as two and a half football fields, Mr. Frantz created "The Amazing Maize Maze"with the help of his family and friends. When it was done, almost two miles of pathways snaked through the cornfield. Since then, thousands of corn mazes have been created around the world.

For many farmers, a corn maze means a boost(激增) of extra income. During the opening weekend, about 6, 000 visitors came to get lost in Mr. Frantz's maze. Charging only $5 per person, he earned almost $32, 000in two weeks.

Brett Herbst is also a maze designer. In 1999 he set a world record for the world's largest corn maze, an image of the solar system with nine planets in it. He now has a business called The Maize, which has designed more than 4, 000 mazes around the world. "Corn mazes help people connectwith their roots, "he says. "People are so far removed from farm life that they are drawn to something real, something organic. "

Today, a great number of people enjoy seeking fun in a corn maze. Mr. Herbst says, "When we see families on the farm having fun, we know that they are making memories that will last a lifetime. "

Many drivers are not very clear about the roads in strange places. Especially, the navigation(导航) just tells the exit number, which makes it easy for drivers to get on the wrong road. However, now you don't have to worry about these complicated(复杂的) roads anymore. Lane(车道)level navigation based on the Beidou satellite system(北斗卫星系统) will be popular in China very soon.

The socalled lanelevel navigation uses highlycorrect technology to show us the real road situation. Compared with past navigation, it can provide exact road guidance in some complicated parts to help drivers choose the best way.

In January 2023, an online map officially introduced an enhanced version(加强版) of lane­level navigation, which helped make good use of the Beidou satellite system more deeply. It greatly improved the speed of receiving information and giving answers and the accuracy of accuracy lanelevel positioning.

In the new version of the online map, lanelevel navigation can be used on all kinds of roads. The new version has a different advantage from the old one: it can guide us clearly where to go in complicated crossings.

In big cities, for drivers who come to these cities for the first time, overhead bridges make it easy to make driving mistakes in strange places. So how does lane­level navigation solve the problem? After careful study, planning and organization, lanelevel navigation uses the Beidou satellite system to improve the positioning accuracy and guide drivers.

For the driverless industry, this map is a good piece of technology, which makes it safer and more widely used.

When Antoine, an international student from Rwanda(卢旺达), first watched the dragon dance,he was surprised and could not wait to join in it. However, the training was not easy. He kept practicing the basic skills day by day to perfectly do the jumps and turns and lift the dragon body high in the air. In 2015, Antoine built the first international student dragon dance team in his school. Now the team has about 100 students from different countries.
