The popularity may depends on the age of the person, but also in the social circles in which those one live.
In the text, the person is still young, and lives in a socially advantaged situation, where popularity depends largely on what we have, how we dress, the house in which we live ...
For instance ("By cons" ??), a person from a poor social backgrounds, could not do it on his popularity, but rather about its talks or ats.
Conversely, a oldest person (Adj toujours avant le nom) socially advantaged, we look closer it is, what it is.
Gné? T'as voulu dire quoi dans cette fin de phrase ?
As someone of the same age, but this time rather poor, its popularity will do what it has and not what it does, what it is ...
Woah... j'ai du mal à saisir le sens de ta phrase, j'crois que tu essaies trop de coller l'anglais sur du français...
In conclusion, we can say that the popularity depends on the age and social backgrounds. And that this is reversed with age.
Ton anglais est trop calqué à du français traduit mot à mot (Google traduction ?). Ta syntaxe et ta grammaire ne sont pas accordées à l'anglais. N'emploie pas "the person" pour dire "la personne qui". Tourne la chose autrement.
2e texte :
First (je pense que "At first", ou "Firstly" sont mieux mais c'est un détail), a prestigious job must be, in my opinion / according to me / as for I (mais pas "for me"), a job that allows us to travel a lot, not only in main tourist destinations like U.S.A., Canada, Japan or Europe. But rather in the world for us to meet other cultures and build relationships around the world. (pas terrible ta syntaxe)
Second important point, money. A prestigious job must get us to earn a big salary (Salaire en anglais se dit plutôt "wages" mais bon ça marche aussi), a housing office, a company car ...
The most important concept of a prestigious job, is that it must be recognized by most people as such, and must be attractive and rewarding. In holding down this work we must respect others and be popular.
It must also have idealistic schedules, as not to start too early, having enough time to eat lunch, finish late at night is not important to me. (syntaxe et grammaire calquée du français) It must also have a weekend to be able to rest after the week.
Last, it should be a holiday.
Une expression qui fera plaisir à ta/ton prof, très courante en anglais:
Last but not least (le dernier point, mais pas des moindre)
Three months per year seems in my opinion/according to me/as for I, well spread over the whole year.
In my opinion/according to me/as for I, a prestigious job is also the ideal job, and that's what I think of a perfect job.
Mouais, je te conseille de lire de l'anglais, n'importe quoi tant que c'est anglais, tu verras que les structures de phrases ne sont pas les mêmes qu'en français, la syntaxe est différente, mais il m'est difficile de te l'expliquer ici.
