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.

1. Write a paragragh about what we should do to save energy. (180 - 200 words)

                                                 Write

Energy is classified into two main groups: renewable and non-renewable.
The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.
Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

We meet many people in our lives, but there are some people who have a great impact on our lives. I admire my mother a lot. She is an ideal housewife of fifty. She was born in a respectable Catholic family. She is very polite, affectionate and intelligent. Besides, she manages the family very nicely. She does every piece of household work. Moreover, she takes great care of all of us. She loves me very darely. She is ready to sacrifice her own happiness for my happiness. She hopes to see me happy even at the cost of her own life. She holds my good above everytthing in the world. Her anxiety knows no bounds if I fall ill. She does not enjoy a wink of sleep. But her face beams with joys when I come around. Next,my mother is very religious. She says her prayers five times a day. Then, she is also very kind to the poor. She tries to help the poor as far as possible. My mom possesses a good sense of sanitation. She keeps our house neat and clean. She is a woman of delicate taste. She reads books when she gets time. She bears a good moral character. She advives us to follow the path of the truth and honesty. She also advises us to be polite, gentle and modest. And finally, I hold my mother in profound respect. I am greatly indebted to my mother.

1...Tìm môi trường nói tiếng Anh chuẩn

Cách học tiếng Anh hiệu quả là tìm môi trường rèn luyện hoàn toàn bằng tiếng Anh. Một trong những quốc gia đang thu hút được nhiều quan tâm của học viên Việt có thể kể đến Philippines. Đảo quốc này không chỉ có môi trường để trau dồi tiếng Anh mà còn tiết kiệm học phí, phù hợp với người Việt. Thời gian đào tạo ngắn nhưng hiệu quả cao, khoảng cách gần Việt Nam và thủ tục đơn giản là những ưu điểm khi du học tiếng Anh tại quốc gia này.

Không chỉ Việt Nam, các bạn trẻ từ các quốc gia không nói tiếng Anh như Hàn Quốc, Nhật Bản, Đài Loan, Thái Lan hay Nga, Iran cũng chọn Philippines là điểm đến học tập. Do đó, có thể thấy sức hút và hiệu quả của việc học tiếng Anh tại Philippines mang lại cho học viên quốc tế.
