As far as we know, in order to use it properly, we must follow its general rules. Facebook is no exception, in order to use Facebook properly, we must first sign up for facebook with a good purpose, not take advantage of that account to do bad things, affect the forum and the public, cause harm to the public. stirring up public opinion, causing many people to lose control... Secondly, about comments on facebook, we do not speak profanity, swear, swear in front of the forum. Third, do not cheat, appropriate another person's property or smear that person. Fourth, do not organize a national reactionary act, do not smear the party or commit reactionary provocations against the state party. Fifth, post articles or comments with good content. Therefore, each person needs to be more conscious in using their own facebook.

I strongly support the use of personal electronic devices in learning because we can’t miss its definite advantages.First of all, they can be used for both research and study purpose. Students can access Internet to download data and store information and textbooks, which save amounts of money for paper books and time. This also means their backpacks are lighter but contain bigger data.Secondly, modern technology tools improve their study results because of a wide variey of useful learning applications on smartphones, laptop, tablets and other media players such as dictionary, spelling, translation, pronunciation and other apps. These apps are not boring but exciting them with colorful designed-courses, funny methods and attractive contents. Furthermore, students can study any time, anywhere as long as their devices are connected to Internet. Last but not least, smartphones help students communicate with each other or relax by listening to music and playing games when they are bored or tired of studying. All types of entertainment are now combined in a small portable equipment, which is convenient for the owners to relax anywhere. In conclusion, personal electronic devices bring more benefits than harm to students. I suggest that teachers allow and encourage the use of these devices in learning both inside and outside of class.

Tôi ủng hộ mạnh mẽ việc sử dụng các thiết bị điện tử cá nhân trong học tập vì chúng ta không thể bỏ lỡ những lợi thế rõ ràng của nó. Trước hết, chúng có thể được sử dụng cho mục đích nghiên cứu và học tập. Sinh viên có thể truy cập Internet để tải dữ liệu và lưu trữ thông tin và sách giáo khoa, giúp tiết kiệm số tiền cho sách và tiết kiệm thời gian. Điều này cũng có nghĩa là ba lô của họ nhẹ hơn nhưng chứa dữ liệu lớn hơn. Thứ hai, các công cụ công nghệ hiện đại cải thiện kết quả học tập của họ nhờ vào nhiều ứng dụng học tập hữu ích trên điện thoại thông minh, máy tính xách tay, máy tính bảng và các phương tiện truyền thông khác như từ điển, đánh vần, dịch và các ứng dụng khác. Những ứng dụng này không phải gây nhàm chán mà còn thú vị với các khóa học được thiết kế đầy màu sắc, phương pháp vui nhộn và nội dung hấp dẫn. Hơn nữa, sinh viên có thể học bất cứ lúc nào, bất cứ nơi nào miễn là thiết bị của họ được kết nối với Internet. Cuối cùng nhưng không kém phần quan trọng, điện thoại thông minh giúp học sinh giao tiếp với nhau hoặc thư giãn bằng cách nghe nhạc và chơi các trò chơi khi họ thấy chán hoặc mệt mỏi vì học. Tất cả các loại giải trí hiện nay được kết hợp trong một thiết bị cầm tay nhỏ, thuận tiện cho các chủ sở hữu thư giãn ở bất cứ đâu. Tóm lại, các thiết bị điện tử cá nhân mang lại nhiều lợi ích hơn là gây hại cho học sinh. Tôi đề nghị giáo viên cho phép và khuyến khích sử dụng các thiết bị này trong học tập cả trong và ngoài lớp học.

Protecting the environment includes the indoor environment and indoor air quality. One way to protect the indoor environment is not to bring indoors any products with surfactants in them. This means switching to safe, non-surfactant cleaners and laundry products. Another way of protecting the indoor environment is not to bring in grooming products that contain phthalates or other volatile organic chemicals or persistent organic particles in them. This means switching to safe, phthalate-free and VOC/POP-free grooming products. This also means switching from manufactured "perfume" fragrances to natural essential oil fragrances, the original perfume material.

Another way is not to bring in bleached recycled paper or plastic products. This includes most food packaging boxes, even organic ones (except for those that have switched to non-bleach/chlorine recycling process products), most meat and poultry trays and plastic wraps, most egg cartons, most ice cream cartons, most recycled school loose-leaf and notebook paper, most plastic bags. Another way is not to walk into the house with your shoes on. The EPA has determined that more than 50 percent of indoor air toxicity comes from petrochemical particulates tracked onto carpets from shoes (worsened when shoe soles are constructed from petrochemical based materials).

Draconian, drastic measures are needed to protect both the outdoor environment and the indoor environment. If our mega-scale free market system worked, we could demand unsafe materials be taken out of production and easily improve indoor air environments, but it doesn't, and we take what we are given while advertising campaigns convince us that what is given is great and the best and that which is what to covet.

It’s a common sense that fossil fuels and non-renewable sources play a vital role in our daily life. They include oil, coal, natural gases, which produce energy and can be seen in every part of life. However, people are using it too much and they are running out, which may make a severe energy crisis around the world. Pollutants released during burning fossil fuels cause air pollution, which affect people’s health and humans’ life. To prevent this from happening, there are some following suggestions. First and for most, reduce the amount of fossil fuels for energy by walking, cycling and using public transport instead of cars or motorbikes. Besides, don’t waste energy, turn off lights before going out or switch off appliances when you don’t use them. Secondly, scientists and government should do research and expand the use of renewable sources such as wind power, solar energy or wave energy, etc. These powers are not only sustainable but green and not produce waste. Finally, awareness should be raised among citizens, especially in education and neighborhood. In conclusion, If people join hands to do big things, we can save the earth from destruction.

My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.
