Today making a phone call is as common as having a glass of water. But when telephones were invented more than 130 years ago, people believed that they were dangerous.
In 1876, when the first telephone was shown to the public, electricity was still new and little understood. Many people had died working with electricity in the early days. That's why most people did not easily accept that it was safe to hear a human voice through the phone.
But on the morning of March 10, 1876, Alexander Bell, and his assistant Thomas Watson, had no such fears. Bell, and Watson had been struggling to make their new invention, the telephone, work. Bell sent his assistant to a room in the basement. In a room upstairs, the telephone inventor spoke seven little words into his invention. These simple words changed the world forever. "Mr. Watson, come here. I want you. "
The telephone was born in March 1876, but it took a few more years for it to gain respect. Bell had to overcome the fears about electricity before people took his invention serious. He also had to convince(使信服) people there was a need for such a machine.

January 27,in order to win the new pneumonia Resistance War(抗击新型肺炎战). Ministry of Education asked to put off the start time of school in spring 2020.
However, many parents are very worried that putting of the start of school may affect children's studies. If they have such a long winter vacation. children will not learn any knowledge, read books or study at all. They may forget what they have learned before Staving at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.
In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice. that is, to organize online teaching and create a network platform(平台), where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.
It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection(感染) of the disease, but also make them study at home, improve their learning ability, and truly achieve "no suspension of classes". Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.
Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.

Dear Grandma,
How are you? I hope you are feeling well and your leg is improving. Can you walk a bit now? Is your neighbor, Mrs. Lu, bringing you enough books to read? I hope so. You'd love our school library, Grandma. There are so many books on all kinds of subjects. The other day I found a book about engineering. I couldn't really understand it but I hope to learn more about this topic sometime. This term I have some new subject classes, so I think I'll tell you about them.
I study biology. It is a very interesting subject. I'm learning all about the human body, where everything is and what it does. Did you know that we have a kissing muscle? It's called “orbicularis” and it's a circle muscle that closes your mouth and moves your lips forward. I love biology. It's so interesting! Another new subject is religion(宗教). I didn't think I would like this one, but actually it is very interesting to hear how different people worship(崇拜). We are learning about lots of religions from all over the world, not only Asia. My other new subject is Spanish. It's really difficult to learn a new language but I know it will be useful for me in the future, if I want to travel around the world.
Spanish is one of the official languages of the European Union and the United Nations. I've learnt that Spanish is not only spoken in Europe but in South America too. Countries like Peru, Bolivia, Chile, and Mexico also speak Spanish. You know I've always wanted to go to Mexico, so if I can speak Spanish, it would be really useful.
Did you study these subjects when you were at school? I suppose subject choice changes over time, doesn't it? I'll come to visit you again in the next holiday, which I think is in eight weeks' time. I'll bring you some of my new books if you like. I hope you can write back soon and tell me all the village news. I miss you very much.
Lots of love,
Sara
