What I like...

I love have loved pets sence since I was a kid.
I have had a beagle, a rabbit and a cockatail  cockatiel when I was kid.

I have worked at a pet shop for about 6 and half years.
I like dogs, cats, rabbits, hamsters, hedgehogs...all of animals.
I have a dog now and  I'm wondering whether to have rabbit again in this year...

よくがんばったね！ ^_^

On the other hand, small stores don't have enough personal (personnel/employees) to open on Sunday, and that would affect to their economic viability, forcing to ( - ) a lot of them to close. That is a problem that large stores don't have.

If small shops were forced to close, neighbours (locals) would have problems to do their little buying during the week (doing their weekly shop), because these local stores are present in almost any neighbourhood, next (near) to the customers' houses and are the more comfortable (convenient) option for everyday shopping.

In conclusion, the government must find a balance among customers, small shops and large stores. A wrong decision can (could) have very negative consequences as the massive close (closure/closing) of small stores and neighbours blaming on the government about that. (could be blamed on the government by the locals.)

5. personal vs personnel

    These two words are very similar so I can understand your confusion. Personal is quite simply the wrong word. If they are too similar, I have suggested "employees" as an alternative.

6. to vs -

    In that sentence you do not need to have the "to" after "forcing". You have a "to" later on.

7.  neighbours vs locals

    I understand what you meant, however "locals" is the correct term.

8. your sentence vs my sentence

    Again, I have just adapted your sentence to make it easier to understand.

9. next vs near

    "Next" only means directly beside something. "Near" means somewhere close by.

10. comfortable vs convenient

    "Comfortable" is more similar to "relaxing", "convenient" is more "easy to get to."

11. can vs could

    Again you are describing a hypothetical situation, so the conditional tense is required.

12. close vs closure/closing

    You got the right root word, however "closure" or "closing" is the correct word.

13. your sentence vs my sentence

    Again I'm just making it easier to understand.

If you have any questions, feel free to ask.

Small stores or big ones

A lot of people think the government should allow large stores to open on Sundays, but that is a controversial decision because small stores would be negative (negatively) affected.On the one hand, consumers will (would) be delighted if they could go shopping on Sundays because during the working week people has not (don't have) much time. Therefore, a one more available day to buy will be well accepted by them.  (Therefore, one extra day to go shopping would be well received by them.)

All in all, a pretty accurate piece of text. there were very few grammatical errors, although the ones that did appear did repeat themselves a few times. I will list for you the reasons I have changed your text.

1. negative vs negatively.

    Negative is an adjective which describes a noun, whereas negatively is an adverb which is used to describe how a verb is performed. Since the word "affected" is a form of a verb you must use an adverb to describe it. If the sentence were, "That would have a negative effect on small stores", then in this case you could use negative, as it is describing "effect", which is a noun. If my explanation is unclear, please indicate your language so I may give you some examples, if possible.

2. will vs would

    "Will" indicates the future tense in English, when used as an auxiliary verb. The future tense is used only if something is certain to happen. Since the situation you are describing is hypothetical, it is better to use the conditional tense.

3. has not vs don't have

    First of all, "has" is the wrong conjugation of the verb "To have" in this case. It should be just "have". Secondly, while not incorrect, this structure is considered very archaic, and in most forms of English, spoken and written, "to do" is used as an auxiliary verb as I have shown above.

4. your sentence vs my sentence

    I could understand the general meaning of your sentence, however I have just worded it slightly differently so that it is easier for a native speaker to understand.

I will write another comment as I have reached the character limit.

    

The end of year's party of my company

The traditional end of year's party of the company which I work in took place on the last Sunday. The majority of my coworkers attended and they brought over their families. We had a traditional Brazilian barbecue alongside with rice and salad. For dessert, we had ice cream, cake and pudding. For drink, we had a 60 liters barrel of a local craft beer, and soda for those who do not drink alcohol. We had a lot of fun and it was very nice enjoying the company of my coworkers outside of the working environment.

The only mistakes iI noticed are highlighted in red.

end of year's - You don't need the apostrophe, people would still understand you if you used it, but it isn't necessary.

on the last Sunday - You don't need to say "on the". In English, you only need to say "last Sunday".

alongside with - I would replace this with the words "accompanied by", because it doesn't make much sense. Alternatively you could just remove "alongside" and that would be fine too.

liters - You don't need the 'S' here. It's a little strange, I agree, but it's just not used. You would say "60 liters of beer", or "a 60 liter barrel of beer."

All in all, easily understandable with only minor and infrequent errors. Good job!

any mistakes?

I believe the impact advertising has on the public is overwhelming. An advertisement often contains features about a product, like how it can save our time, bring convenience, etc. Also, a commercial tries to appeal to the prospective customers emotionally. Then the public can be stimulated to become interested in or have a desire for the publicized object. Besides, when people are trying to decide which brand of a certain type of products to buy and the prices do not differ beyond 10%, they tend to choose one that they are more familiar with (as is seen or heard in a advertisement), because humans have by nature a fear for the unknown. Consequently, advertising exerts a decisive influence on people’s choice.

That's perfect apart from that.

My life style (movies)

I like watching movies.
When I have free time, I usually watch movies at home.
Sometimes, I go the movie theater, but the cost is almost double the price in Japan compared to here, so I don't go there very often.
And also I prefer watching movies in my house because I can stop the movie If I want.
So I only go to the movie theater when I want to see action movies.

As I told you yesterday, I have watched 100 movies in the last 4 years.
The reason I did that was because I was searching for some ideas.
I was worried about my job, my future, everything.
But sometimes watching movies was hard for me at that time because some movies tell dark or depressing stories. So It made me more sick. So, when I wanted to just have fun, I prefered to watch comedy or action movies.

So in the last 4 years, I watched many kinds of movies such as comedies, dramas, action movies,  romances and so on.  Also I watched many foreign movies such as American, French, Italian, and sometimes Korean.

I often asked my friend, who is crazy about movies. She often recommended me some movies.
But her taste and my taste are a little bit different, so some of the movies that she recommended me felt boring.
She likes french movies and her taste is very artistic, so I couldn't appreciate how interesting the movies are. Actually, I don't like french movies very much. I watch them, but they're complicated and too long for me.
Usually french movies are 3 hours long. I can't stand that.....

I watch movies all the time!
In my case, I watch the movies that I love again.
Before I go to bed, or while I get to ready for work or during cleaning.
Even now, I sleep while watching movies. It's my habit.
Since I live by myself, I usually do that because when I hear some noise, I can't sleep well.
After I left my home town and started to live by myself, I lived in an apartment. Then my neighbors would make a noise in the middle of the night or I'd even hear foot steps, I can't stand it. In my case, I can sleep in noisy places, I just don't like the idea that shows there is someone in my house.

I know, it's weird.....It is one of my problems. If I'm really tired, I can sleep without movies.
I hope, I can sleep well without movies someday.
