30天中文写作挑战 (4/30) - 我的故乡

Comme d'habitude, je te donne une amélioration puisqu'il y a déjà deux corrections

今天，我要讲讲我的故乡。我现在住在巴黎附近，但我的故乡是Le  Mans，那是一座坐落在法国西部的小城市，居民约为十五万左右。
勒芒以"勒芒24小时耐力赛"闻名，每次比赛汇集了世界各地的赛车手。在勒芒，坐落着一个中世纪的老城和一个大教堂。我真的很喜欢在那儿漫步。我觉得我不会在勒芒定居，但我很高兴能经常回去看我的父母和姐姐们。

Onto day 4 of my personal writing challenge, I am very happy to have so many feedbacks each day! Be assured that I read all of your feedbacks and take time to review them. I have a notebook where I write all the different ways proposed by you to explain my ideas. Thank you in advance for today's help! Here is the English translation of what I want to say in Chinese :

Today, I want to talk about my birthplace. Right now I live near Paris, but my native city is called Le Mans. It is a small city on the west side of France. There are around 150,000 inhabitants there. Le Mans is very famous for its car race "The 24 hours of Le Mans”. Racing driver come there from all over the world. Le Mans also have a medieval city and a cathedral. I really like to stroll there. I think that I will not come back to live in Le Mans, but I am always happy to go back to see my parents and my sisters.

现在我住在巴黎附近，可是我的故乡城市叫Le Mans。

故乡 is already a place, usually referred to a city or a town, so you don't have to add  城市. 

那是一个法国西部小城市。在那里有周围大概十五万居民。

那 means Le Mans,  the basic structure of Chinese sentences is subject+ verb+ object. 是 is a verb, 一个法国西部小城市 is the object, so before  是 you should add a subject, like Le Mans, or 那.

Le Mans 对它的赛车比赛 "勒芒24小时耐力赛" 很有名。

You were not supposed to translate English into Chinese directly...

全世界的赛车手都来到去那里。1*

Le Mans 也有一个中世纪老城古城和一个大教堂。

I would rather saying 古城, but if you say 老城 people can also understand you. 

我真喜欢游在那里散步／闲逛。

Stroll: 闲逛，溜达，散步。

我觉得我不要住在会回Le Mans住，但是我一直高兴回来去看我的父母和我的姐姐。2*
Will: 会

1* & 2*: 来：You're at that place, and people are coming.  i.g.公共汽车来了。 Here comes the bus. / You're at the bus stop while the bus is coming. 

去：You're not at that place but you're going there. i.g. 从北京去上海 Go from Beijing to Shanghai (leave Beijing for Shanghai)/ You're in BJ a you're leaving for SH.
