Have you ever asked your relatives or friends if there is Wi-Fi in their houses? Have you ever searched for Wi-Fi when you are at restaurants or hotels? The answers will probably be "Yes". Most of us want Wi-Fi everywhere as if we can't live without it. But we can only use free Wi-Fi in some public places. We still have to spend some money accessing(连接)the Internet at most time. Here comes a piece of good news.

    A rich, powerful organization(组织) in the USA called the Media Development Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. They will send up hundreds of satellites into low Earth orbit(轨道).

    This is because they have made a survey(调查) and found that only 60% of the world's population have been able to get information on the Internet. And this is also because many countries are unable to offer people the necessary infrastructure(基础设施)to access the web.

    We can hope to use free Wi-Fi everywhere in the near future.

    My name is Carla. My school is big and beautiful. Here is a map of it. Where is the classroom building? It is next to the office building. Our teachers work in the office building. Behind the office building, there is a sports hall. The dining hall is on the left of the sports hall. It is also near a pay phone（付费电话）. The playground is between the library and the science building. I like the library very much. Oh, look at the students' dormitory（宿舍） building. It is in front of the science building!

    Leonardo da Vinci (莱奥纳多·达多奇) was a famous artist who was born in Italy. He was also a great inventor. Many of his inventions have become important in modern life. Although Leonardo hated war, he invented many different machines used for war. His most special invention was the machine gun, which was produced and used in war. Besides, Leonardo spent days thinking about how to save time. He developed ideas for something like cutting machines.

    Leonard was a strange man. He never ate meat. That was very unusual in those times ( 时代). He never published (发表) scientific discoveries. He usually used mirror writing, which looks like usual writing in a mirror, starting from the right side of the page and moving to the left side.

    Only a few of his paintings are left today. Many paintings were not finished because he thought they were not perfect.

    Leonardo was talented and creative. He was regarded as one of the most intelligent men in the world.
