你好！我叫Rachel。

你好！我叫Rachel。

你好！我叫Rachel。

你好！我叫Rachel，我是英国人，我家住在伦敦，家不大。我喜欢中文，星期二和星期四我有中文课，我们中文班有十一名学生。我没有哥哥姐姐，但是我有一只小狗，他叫Harry。

我喜欢吃米饭和牛肉；我喜欢喝茶和水。

我的生日是九月十七号。

今天很热，昨天很冷。

再见！ ：）
 

I am glad your Chinese is really good, but you’d better pay more attention on your punctuations. The usage of punctuations in Chinese and in English is a little bit different. You have to use a period at the end of each full sentence in English (I mean the sentence is already full of subject and verb and object in grammar), but in Chinese we will never use periods that frequently. We only use a period at the end of several sentences when we think one thing or view has already been stated (I mean those sentences are already finished in logic, but not linguistic.).
