The answer from the hotel says: the room needs to be paid upon arrival. UPON??? What does UPON mean here? Before or as soon as I arrive?

My IELTS essay 2. It is true to say that becoming a good member of society is a rough task for a child. But whose task is it, first of all, to teach and direct a child: children’s parents or school? To begin with, parents are, undoubtedly, major people in any child’s life. They spend most time together during first several years. Moreover, mothers and fathers help their child to learn essential things about how the world is arranged. Besides, a child always takes an example after his parents, so these people are mostly responsible for his developing personality. Every step they take should be measured and thought twice. On the other hand, when a child gets older, there is school, which takes a hefty part of his everyday life. That’s another new world, where he or she learns how to get acquainted with other children, make friends and be in touch with them. Teachers at school are people who replace parents, while a child is at the lesson. As a result, these people have a huge influence on kids. Needless to say, school is responsible not only for children’s success in studies, but for their personality advancement as well. Personally, I believe that both these sides, parents and school, have almost equal duties in front of a child, because their interference is simultaneous and massive. Nevertheless, I give the first place to moms and dads, because it is in a circle of their interest to raise a good member of a society and above all a kind and a truly good man. (259)

My IELTS essay. In many countries people tend to put on extra kilograms while their health is deteriorating more and more because of this. Nowadays people in developed countries spend the most of their time being busy at work. They do their best to earn enough so that they could increase their lifespan. But does it really help them to achieve their goal? In fact, people overwork during the week, as a result they feel exhausted and the only two things they want to do is to eat and sleep as soon as possible. They have no wish or force to do anything else. That is, actually, why they have to make a dive into some fast food restaurant on their way home. As a consequence people get used to eating junk food which is tasty, not expensive and easy to find. Moreover, busy people do not spend enough time in the fresh air playing volleyball or jogging. They prefer finishing their work instead which also influences their shape and health. Besides, for being in touch with friends or relatives you do not really need to leave your coach and go somewhere out because everything you need today is a smartphone or a PC. Such life style is sure to lead to health and fitness decreasing. Nevertheless, I believe that there are ways to solve these pressing problems. A human being is a social creature and he is easily influenced by everything he sees or hears. Such particularity should be used to turn people around so that they kept a healthy lifestyle. For instance, active kinds of sport must be promoted on TV or on the Web by celebrities. Besides, healthy food needs to be advertised as the only way to stay young and beautiful for many years.
