Blue blood

The phrase (or 'term'?? not too sure what you mean) "blue blood" is about an aristocratic man. Scientists say that the human blood is red in colour, because the blood has hemoglobin in which contains ions of iron. Some mollusks and arthropods has have hemocyanin in their blood. Hemocyanin has ions of copper, which gives them their blue colour.

Very advanced piece of writing- great work! Only thing I'm not sure about is the first sentence... depending on what you mean, you may be better off saying;

'The term 'blue blood' is used when talking about an aristocratic man'

But I'll leave that up to you :)

We have received your letter of dated 15 June and it has been delivered to our Shanghai branch. They will reply directly to you, because as these commodities you inquired about are in their product stock.


'To You' in brackets as I don't think it's necessary, but that is your choice.

Hope this helps :)  

The Community Center

After work, I went to the community center to play badminton. It has a drop-in schedule for it from 6pm to 7:45pm. When I got in there 15 minutes before drop-in started, there were already lots of people waiting for it. The receptionist said that it had a regulation that a maximum of 16 people only 16 people could play at the same time and now there were over 16 people.

I regretted not signing up through  by phone in advance before coming here  going there. Accordingly, I had to wait until someone who had signed up already had their booking cancelled due to not showing up even 10 minutes after drop-in had started starts.

Luckily, I was able to get in could get in only 10 minutes after drop-in had started starts. Perhaps because lots of people on the waiting list had expected that they wouldn't get in, and had left. they left there.

Great English! Corrected a few things, and changed a few phrases to make them sound a little better. Hope this helps!

I hope you will get better soon and that you'll always be healthy. It is normal that after such a serious operation you feel tired and exhausted. It is great that you are at home with your family after having stayed such long time in the hospital.

Two days ago was my daughter's birthday. We celebrated it modestly- only two cakes- but I bought her many nice clothes and a golden chain and bought small cakes and small bottles of juice for the children in order to give them at a small party in the kindergarden.

She was very happy that it was her Birthday. As for me, I am so indifferent to this holiday- every Birthday you get older and it is not a fun thought!

Today I went to the Immigration office to deal with my mum's immigration process. Again, huge queues and you have to wait in a small coridor without any windows. It was so hot there that you wouldn't believe that only two months ago everything was covered with snow and it was frosty.
Once again, my journey there was unsuccessful and there were so many people that I queued to no avail.

Your English is fantastic! I made a few small adjustments but overall that was incredibly well-written. I would love to be able to write like you in a second language! The only part I am confused with is the section in bold. Do you mean that you gave up on waiting because the queue was so long?

 

Hello! My name is Evgeniy, and I am a Security Systems Engineer. 

I would like to work in your company.
I think that your company is the best choice/ option/ company (?) for me.
I have been working in this industry/ position for more than 6 years and I have a lot of experience.


I have made a few small corrections. Apologies that I don't understand what you mean in your sentance; 'I think that your company is the best...'

Also, in the final sentance, use 'position' if you have been working in that specific job role and 'industry' if you have done similar- but not identical- jobs in the past.

Hope this helps!
