Greeting

Hello everyone ! I'm new here , my name is Oussema and I'm from Tunisia. I speak Arabic fluently, because Arabic is my native language. I hope that I can help others to learn Arabic and others can help me to learn English.
This is my first test paragraph here

I'm assuming you mean "A's B" or "B of A" They're sort of interchangeable but "B of A" is very formal, and applies to a lot of cases where "A's B" would not. "A's B" implies possession always, while "B of A" is more of an indicator of relation or used to describe a thing. For Example: "John's car" sound much more natural than "The car of John". Even though the latter is technically correct, it sounds very formal and odd. "The President of the United States" and "USA's President" are interchangeable, but the latter is much more informal. "College of Science" and "Science's College" are not interchangeable, because in this case "of" is used to show what the college is about, not to imply possession.

Your use of "not" is fine, but the word order is off. The correct way to say it would be "Your perspective is not always true" Not is usually not used at the beginning of sentences. Think of "Not every" as a set phrase.

It really depends. Most people unconsciously speak very fast in their native language, and it's never going to be as slow and articulate as in instructional videos. Try watching some videos made by English speakers for English speakers, especially for the dialect/region you're planning to communicate with most, and you'll get a feel for it. Some types of English are hard even for people who speak English natively, for example, Scottish or Deep South American English.

Hello World

I want to write a lot of diaries of myself in English. I also want to say a lot about of words of myself in English. In my opinion, the existence purpose of the language is not for testing mechanically or flaunting over those people who are uninterested, and not even not for pursuing the competency. It's purely a quest for language itself, its pleasure and anxiety inside and out, its enormous significance from persons to persons. In a word, it should be an art, a new horizon and the a way of thinking about something differently. But it's a great mockery for me. It's seems that I am being in a ridiculous dilemma. For one thing, I have an urgent enthusiasm for it like a small kid. For another thing, I can't harbor the courage to communicate with people who I want to talk with all the time and everywhere like a small kid. I am too burdened too much by other's perspectives, I can't break through where I live, I can't do as the elite do and engage a private tutor or attend an utility course or such. Additionally, my eyes are too delicate from radiation to learn from the web often. All I only possess at present are the scarce resources I have and a heart of abounding with conviction and enjoyment. Please listen! A slight voice from the Orient is saying: hello world! Thank you very much!

I lost my express package yesterday

Last Saturday was the double 11 Shopping Festival, so I bought several things online shopping which did saved me nearly half of my money. Soon I received my first express package on yesterday morning when while I was working, I found it was the dark blue down-filled coat for my mum. Since it was not for me ,so I just took away the it out of the outside packaging and left the inside as the way it was. I decided to take it home after work so that my mum could try it on herself for the first time. When it was time to go home，I took the coat with me to the metro and found a seat , I put it on the seat leaned it on the back of the seat. Everything seemed to be going on well by then，however soon something bad happened，I forgot to bring the coat with me when I got off， what's more，I didn't realize that uill I had to transfer to another Transfer Line. I turned to the staff for help as soon as I found out that I my cost lost my coat，but it was useless because there were such a huge number of passengers on each train. Although the staff asked me to leave my number in case they found my coat，I was not hopeful. What a bad luck I've got I had such bad luck yesterday，I even was not even able to open the unfolded clothes in time，however and I lost it forever. I have not told my mum about this bad luck. As it for her，It's better for her not to know than to know。
