Each summer vacation, I am taken to the countryside by my parents so as to relax after a hard working term. I really like the life here. In rural areas, there are not as many houses and vehicles as in the city. As the result, the atmosphere is quite fresh and cool. Most people mainly travel by bicycle or on foot. The landscape is very poetic and picturesque. There are many gardens, rivers here. We can grow vegetables or chickens, fish,... on our own. The local are very kind, generous and friendly. They are willing to give directions to strangers and help each other in difficult times. Whenever we are away, we can relievedly ask our neighbors to keep our houses and children . Another thing that we especially like is that in the countryside, we are reconciled to nature so that the soul is always open and the body is healthy. Living in the countryside is fun and wonderful. In the future, I really want to live here.
In the modern life, there is an increase in the people leave the countryside and migrate to the city. The objective reason is that in the city, it brings them comfortable life and favorite job. Subjective causes are due to the following disadvantages rural areas bring about push residents away. To begin with, there is no denial that rural infrastructure is not modern and advanced. Roads are quite narrow and degraded. Schools, hospitals are not cared much and remodeled. Especially the quality teachers and doctors here are just little so the inhabitants have less opportunity to develop in all way than in the urban area. Last but not least, the biggest disadvantage in rural areas is that job opportunities are so race. The main job is craft, farming, which bring a relatively small income. With that salary, we can only live through the day, not afford for services, shopping, entertainment… In conclusion, besides the positive aspects, life in the countryside is very much. disadvantage. We all need to consider carefully before choosing where to live.
Lời giải:
Vì $a$ là số nguyên tố lớn hơn $3$ nên $a$ có thể có dạng $6k+1, 6k+5$ với $k\in\mathbb{N}$
Nếu $a=6k+5\Rightarrow 10a+1=10(6k+5)+1=60k+51=3(20k+17)\vdots 3$ và $10a+1>3$ nên $10a+1$ không thể là số nguyên tố (trái giá thiết)
Do đó $a=6k+1$
Khi đó: $5a+1=5(6k+1)+1=6(5k+1)\vdots 6$ (đpcm)

I think people might still say BTS can not sing.In fact, there is a very good harmony among BTS members. They highlighted the rap because they were a hiphop group but they added emotional vocals instead of vocals full of internal strength and that was of course balanced but the bad guys would assume that the singer Not screaming high notes are bad singers..but I think BTS does not intend to make the vocals stronger. I think they balance each other very well now and I feel sorry for them when someone says they are incompetent, they are a very talented team. Each time I hear them sing, I feel the life is flooding in me,which they bring for me is inspiration. Thanks you, BTS

Tôi bắt đầu học tiếng Anh từ khi tôi học cấp hai, và tôi nhận ra mình đã thu được rất nhiều lợi ích từ việc học ngôn ngữ đó. Đầu tiên, tiếng Anh khiến tôi trở nên tự tin hơn rất nhiều trong việc giao tiếp và phát biểu ý kiến của mình. Thông qua việc rèn luyện ở những buổi học nói, tôi có thể phát triển cả hai kĩ năng giao tiếp và phát âm. Thứ hai, tiếng Anh là một môn hỗ trợ rất tốt cho kĩ năng viết của tôi. Bằng cách theo sát các ngữ pháp có sẵn, tôi dần biết được cách làm thế nào để có lập luận thuyết phục hơn cũng như cho được các ví dụ minh họa. Thứ ba, kĩ năng nghe giúp tôi chú ý hơn vào các chi tiết trong mỗi cuộc hội thoại. Điều đó giúp tôi thu thập được nhiều thông tin chính trong một khoảng thời gian ngắn. Bên cạnh đó, tôi còn có thể phát triển kĩ năng ghi chú của mình vì việc có một ghi chú tốt trong quá trình nghe giảng là một việc cần thiết. Cuối cùng, những gì tôi học được từ kĩ năng đọc có thể được áp dụng hoàn hảo cho việc đọc bất kì một nguồn tài liệu nào. Bằng cách lướt và quét thông tin, tôi có thể hiểu được toàn bộ những ý chính của mỗi trang. Kết lại rằng tất cả bốn kĩ năng trong tiếng Anh đều có thể giúp tôi một cách cụ thể trong nhiều khía cạnh. Tôi vui vì mình đã học tiếng Anh kể từ khi còn nhỏ, và tôi sẽ tiếp tục rèn luyện nó nhiều hơn nữa.
Nowadays, English is an international language, and most young people are learning this language with the hope of being able to communicate with people on over the world. English has become a compulsory subject at most schools, and a lot of people go to foreign language teaching centers to improve their skills. Learning English is not just limited in memorizing vocabulary and grammar, but it is also a process of training and improving listening, speaking, reading, and writing skill. We should focus on these four elements, because each skill will have the necessary content to complement the other three. We improve our speaking skill if we can listen to and understand what people say; and if we can master our vocabulary and grammar, we can write and read easily. Apart from spending the time to prace, we also need to be creative in learning English. Textbooks at schools and English-teaching centers are just basic steps, so we need to be proactive in finding more resources. There are a lot of movies, music and books written in English nowadays, and we can learn a lot from them. In short, learning English is a long process, but it will be easier if we can find the right and effective ways to learn.
