One of the undesirable aspects of tourism development is environmental degradation in destinations. Firstly, more and more natural resources such as water, energy, and soil are exploited due to the increase in visitor numbers, which may lead to the depletion of local resources. Secondly, pollution is also a serious issue making the authorities worried. Obviously, beverage bottles or cans and plastic bags are freely disposed of at the tourist sites, posing a threat to the natural environment. Besides, the growth of vehicles to meet travel demand accidentally triggers or worsens traffic congestion, air and noise pollution in the overcrowded regions. Another bad influence of tourism is the devastation of the wildlife. The habitats of many wild plants and animals have been gradually lost because of building hotels, resorts and recreational zones. In brief, these negative impacts on the environment will be more serious if there are not appropriate measures.
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)

Everyone has their own study habits which are suitable to their routines. Personally, I have to go to school in the morning on weekdays, therefore, I spend the afternoon doing the homework. At night, after eating dinner, I often relax for a while by surfing Facebook or Youtube, and then come back to my desk. If the homework is completed, I normally practice some extra English exercises. My mother has bought several English learning books for me. On Monday and Tuesday, I have an extra course in Mathematics, so I’m a little bit busy those days. In addition, being interested in editing videos, I usually spend my free time watching videos on Youtube about this topic and practicing it myself.
English is an international language.It is very popular in the world.Therefore,I like to learn English very much.There are many reasons for learning English but I have three main reasons for it:find a good job,communicate with foreigners and especially catch up with the age. Firstly,we learn English to find a good job easily after graduation from college. I think it is right. If we want to work in foreign companies with high salary,first of all we have to know to use English.We have to write CV in English and speak English to employer in an interview that required.And I am sure that if we are good at English and a little experience in work we get,we will have a good job with high salary that we always want.Secondly,communicating in English with foreigners is very useful.Actually,we have many opportunities to learn and understand clearly about differences between British and American English.Moreover,they will correct us when we make mistakes in using words in English.That helps us improve English very much. Thirdly,we are living in the area of information technology.Therefore,we have to use personal computer in our work.And if we know English,we can read English News to know what happening in the world,listen to our favourite English songs or play games in free time.And it is very useful for us to relax after hard working days.Learning English brings us many opportunities to catch up the age.We can broaden knowledge and study many things from it.We can know about cultures,manners and customs from many countries in the world. Therefore,right now we have to study English to prepare for our lives in the future.And we always hope we can do everything if we try to best.That makes us successful in life.

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!

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.

+ 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.
