Technology is now a big part of our society and our predictable future. There is little room for people who wish to live without technology, and luckily, it is still advancing at a rate that has helped stave off stagnation. I believe that for every advantage that technology brings us, it also brings us a disadvantage at the same time.
Smartphones enable people to stay in touch, even over long distances, and they are relatively safe and reliable to use. There are devices that people can use to communicate with plus at the other end of the planet and getting and keeping in touch with other people is very easy.
The disadvantages of smartphone is that it means people no longer need to meet in person as much, and interpersonal relationships are suffering worldwide because people are communicating through a small handheld device. A lot of people have smartphones and they use them almost semi-continuously, including in public settings when they could be making new friends, finding new lovers, and interacting with their current friends.
The advantages of the internet are that people can communicate over vast distances and can gain access to information and get answers to their questions very quickly. The disadvantage is that the Internet isn’t moderated in the way that people think and lots of it is filled with misinformation and outright lies.
Even brand-named websites which have a lot of trust are not accountable for what appears on their own websites. Even respected and branded news sites have stories that have passed through many people’s hands and originally started as lies with zero accountability throughout the dissemination process.
In conclusion, technology brings about such a lot of advantages. However, it’s people’s duty to use it in an appropriate way to make it beneficial.

My home village is now different from the village in my father's story. in his story, my village is very poor.
Everyone live a hard life that time. People lack of food, of money. Now, it is different. People don't live a hard life anymore. They have enough food, enough money, everyone got a house, and many more things. The only things that doesn't change is sentiment. Everyone always be very happy. They live together, help each other when they need, that is a luxury.
That makes my village a wonderful place for everyone. People are just farmer, but they solidarity in the face of penury. And when they have money in their hands, they still solidarity they are friendly with others, they are helpful, they are good people. That's about people.
Landscape is still like the old days. That river, that mountain. Nature is harmony with people. People live with nature, people product things of nature, and nature always open-handed with people, give them resource for them to build their house. That is what people seek, and they live with it very well.
That's all I can say about my home village, in my opinion, my village is a wonderful place. War does not determine who is right, only who is left:" Ask not what your country can do for you but what you can do for your country"

Young people nowadays have a new form of entertainment in addition to typical ones, and that is the Internet. Only by looking at the computer screen or smart phone, we can reach to a vast and exciting world of Internet. The Internet is where people around the world share information, images and videos, so it is an interesting and almost endless space of entertaining. We can watch movies, listen to music, read books, play games, read newspapers and do many other things on the Internet. In addition, making friends and posting interesting moments on social networking sites is also an integral part of the Internet. Some top applications such as Facebook, Youtube, Snapchat, Twitter, Instagram, etc always attract a lot of users, and most of them are young people. However, it now seems that the Internet has consumed too much of our time, and we are limiting our forms of entertainment through the abuse of Internet. Many young people become passive or choose to separate themselves from the outside world, and they just looking for joy that comes from the phone screen. We do not deny the pleasures of the Internet, but we also need to combine other outdoor activities with surfing the web. Internet is a great form of entertainment, but in my opinion we should not replace our traditional entertainment activities with it.
