Bonjour,  
On peut me corriger et m'améliorer mon texte
Isaac Berlin was a Jewish poor man born in Russia. He had 5 brothers.  
 
Isaac Berlin's travel was very long and hard.  
At first, he took a train.  
Then, he sailed from Hamburg to Liverpool.  
Finally, he left Liverpool in the way to go to New York.  
 
In the boat, the conditions were horrible. There was no hygienic, no separate toilet and no shower. They lacked water and food.
When there arrived in New York, they're exciting because they can see the Statue of Liberty and their new life start.
But before, they went to Ellis Island which was the immigration station. First, they would undergo a medical examination. After that, the officials checked their papers. Then, they asked the immigrants some questions. Now, they can can go to New York.
Life was not easy when they arrived in New York. They have no house and no place to sleep ... but the biggest difficulty was that they cannot speak English.

(commentaire: beaucoup trop de d'abord, ensuite, enfin).
 
edit: typo

Bon bah grillé par fzzbnn (m'en suis rendu compte après avoir tapé ma réponse).
Juste une remarque, c'est hygiene, avec un i.

Effectivement j'avais pas vu, danke.

Autre chose, je dirais plutôt "poor Jewish man" à la place de "Jewish poor man", "jewish" étant l'adjectif le plus important, il se trouve donc le plus proche du nom...

Disappeared cette phrase :s (reinserée)
 
Hésites pas si tu veux remanier, pour une fois que c'est pas moi qui me fait griller

J'ai rien à redire sur ta correction, t'as viré les fautes et t'as même un peu remanié habilement la forme
