As we all know, the Covid 19 epidemic brought a lot of damage to people and property. It a very dangerous disease and highly contagious from person to person. It seriously affects the economic conditions of countries, especially the US, Brazil, and Russia. This epidemic originated in Wuhan, China. And now there are many strains and can spread faster and stronger than the original virus. The Covid 19 epidemic has claimed many lives of people in the world and in Vietnam. For the above reasons, we need to accumulate epidemic prevention, each of us should be conscious, this can protect the health of ourselves and everyone in society. Especially doctors are on the front line against the epidemic, who are facing many dangers, but still risk their lives to treat patients. Need to strictly comply with the directives of the state. To protect ourselves and everyone we should do the following:
+ Wear a mask when going out to public areas, crowded.
+ Antiseptic and daily body temperature measurement.
+ When you yourself have symptoms of cough, shortness of breath, you should contact the hotline of the health department.
+ Download the Bluezoon app to make a daily medical declaration.
+ Not gathering people, needing to stop weddings, anniversaries, ...
+ If you go from the translation area, you need to isolate in accordance with regulations, do not try to hide, because it will affect people a lot.
+ Do not bring foreigners in illegally via the border.
+ .....
The above are the basic things that each of us needs to do to help the country soon end its epidemic.
This is my personal opinion, I think our state needs to deal strongly with people who illegally cross the border, spreading false information that confuses people. Because when we make strict laws, people will not consciously do something without thinking.
Each of us needs to work together to fight the Covid 19 epidemic.

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)

Life has changed a lot over the past 50 years, and there are many good pastimes which seem to be dying out. Work in groups and search for a past tradition or pastime which you highly appreciate give reasons why you like it work out a plan to help preserve it. Then make a poster presenting your ideas and share it with your class.
Life in the countryside is quite different from that in the city. First, it is the atmosphere that differentiates the two living environments. In the countryside, the air and water are much fresher and safer, thus living there is totally comfortable and beneficial for our health. In contrast, people who live in big cities suffer from health problems and diseases related to poor air quality and sources of polluted water. Second, prices and costs of living are cheaper in the countryside than in big cities. Vegetables, fruits and meats are home-grown and home-produced. However, in cities, people have to go shopping for them. Third, the interpersional relationships are more harmonious and friendlier. Those who live in the same village, especially neighbours, for example, know each other very well. There is a close-knit cooperation between people in working and many other daily activities. On the contrary, negatively speaking, city people only live and know their own business. They hardly care about who their neighbours are and what they do. Sending a helping hand, as a result, is never seen among city people. In conclusion, although the city life holds many advantages that make life more convenient, I always prefer living in the countryside where the environment is nice, the costs of living is affordable, and the intimate relationships among people are really meaningful. Personally, If I had a choice between a villa in the city and a small house with garden surrounding, the latter would seem better to me.
Life in the village is simple and warm! People here legs covered their faces mud but loyal and beautiful, lasting impression. The children here do this joke sick child mice skinny, black, curly hair, bare ride runs between lunch fields. Every morning, I saw her in the village to the river carrying water, laundry, wash the rice, the farmer ... The field, rice paddy. The students go to school. The vegetables and flowers she brought to market. At noon, the farmer resting, sitting beneath a banyan tree and enlist dinner nap a few minutes. This time the students had gone home. Afternoon, I found out the first lane 1 basket she brought only a few bundles left over after selling vegetables at the market, the buffalo farmer after 1 business day. Buffalo designs ample tread it looks majestic. Children flying a kite to the kite fold, brought home and agreed to meet the next day! Every evening, the breeze through blow away the smell of rice fat fat. Oh, I love this peaceful life too, it's a far cry from one life is full of sound in the city, do not take well 1 sec quiet!
In school, there is a subject which I am interested in very much, and it is English. English - a subject that teaches me how to pronounce and speak in its language. It provides wordform, phrasal verbs, grammar and the accent you need to know to speak in English.
At first, when I got to know it, I didn't good at English because it was too new and strange for me. In that time, I was bad at speaking and writting, cause you need to pronounce correctly so the foreigner can understand what you said. Therefore, I started learning carefully, practiced on using grammar in writting and tried to speak everyday in front of the mirror.
Time goes by, my score in English is getting higher and this mades me happy. I started to love English and even took part in competitions and other activities. There was a once time I got second place. What an unforgetable time!
Now, I always remind me to keep forward and learn new things to improve my English. That why you shouldn't give up a subject for it's difficulty, if you spend time to learn and get used to it, you will good at that subject soon!
