I still remember, when I was 10 years old, my parents let me go to my hometown to play. It is a beautiful peaceful countryside with vast rice fields. It was summer, it was hot, in the afternoon I went to the dike to strip my house and play kites with some kids near my house, I must say it was fun. I also enjoyed the fish cooked by her own hands. Around 5 pm, I went to the river to bathe, the water was cool, I played in the water until more than 6 o'clock. In the evening, I and my friends went to the field to catch fireflies. At that time, it was so fun, but not like now, every child is glued to the TV, computer, phone. I will always remember that trip.

Why learn English every day?
English is the most useful language. When we are good at English, we can go to anywhere or any country we want. We will not find it difficult to make others understand what we mean.
English also helps us to understand all kinds of objects. Hundreds of books are written in English everyday in all countries to teach people useful things.
Because English is used so much in every corner of the world, it has helped the world to become more friendly. The leaders of the world use English to understand each other. Thus the English language has spread better understanding and friendship among countries in the world.
Finally, as a person who knows English easily get a lot of knowledge from many parts of the world, they are respected with everyone. That's all the reasons I want to learn English.
The development of tourism has led to a possibility that space travel will be widely available in the future. However, I would contend that this form of travel is the negative development for the following reasons.
To begin with, there are many negative aspects of space travel. Firstly, the equipment required for this means of travel is relatively expensive because money needed to produce aircrafts is far more than the amount for other vehicles. Secondly, space tourism causes environmental contamination. When operating, aircrafts release huge amount of exhaust fumes into the surroundings, and the ozone layer will be seriously affected while the rockets are launched. Finally, travellers would face the risk of problems related to health. Visiting a strange star is a potential danger because there are circumstances that we cannot control or give first aid whenever necessary.
Some people may claim that space travel can broaden our knowledge of the universe. However, I believe that planets where no life exists have nothing to visit, except for stones and rough surfaces. In lieu of taking the tour, people can have many other ways to gain knowledge of the planets and the universe by reading science books and watching science movies to be safer and less costly. The purposes of travelling base largely on relaxation and discovery; therefore, no justification would be rational to justify the growth of space tourism. That is the reason why many people reject the development of space travel.
In conclusion, I firmly hold the view that space tourism has many drawbacks than benefits, and the development of this industry should not be promoted.
Hello everyone, today I will talk about Mars, the 4th planet in our solar system. The name of Mars originally comes from the name of the Roman god of war and agriculture. It may not seem like these two things go together, but they do. Mars protected those who fought for their communities and stayed home to raise crops for food. Mars has two natural satellites, and their names are Phobos and Deimos. With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. The atmosphere of Mars is much thinner than Earth's. It contains more than 95% carbon dioxide and much less than 1% oxygen. Mar's temperatures are from -151°C to 20°C. Mars is colder than Earth. If you were to stand on the surface of Mars on the equator at noon, it would feel like spring at your feet and winter at your head. Mar's surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. It's called Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red. One day on Mars takes a little over 24 hours. Mars makes a complete orbit around the Sun in 687 days. Thanks for listening.

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)
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.
