User: Title: Результаты марафона "Русский 2021": разбор ошибок, победители и участники!
Caption: Hello everyone, dear friends! Welcome! Today we will finally sum up the results of our
Russian 2021 marathon. To begin with, we will have some statistics: I will tell you how many
people participated in the marathon, from which countries, and so on. Then I will comment on the
most difficult moments of the marathon - where 99 percent of the students made mistakes.
And finally, I will announce the winners - the most active participants in our marathon. So let's get started.
Before we start, a very important comment! Our marathon was called "Russian 2021". It's just the
name of the marathon. Of course, because the marathon lasted 21 days and because it is now 2021. Attention!
Exactly: what year is it? Two thousand twenty one. If we say what year it is, we do not say
"20-21", I just named the marathon so that it would be easier and faster to pronounce the name of the marathon.
Well, now we can start. Let's start with some statistics. There are 143 people in our Facebook group,
but in fact, more participants watched our marathon. So, for example, our first video - day
number one - has already been watched by more than 1000 people. Well, about 30 percent reached the end - about
300 people, a little more, watched the last video - day number 21. I wanted to choose the
best assignment, the best video of the marathon and asked you to write in the comments which
video you liked the most. But, to be honest, I couldn't choose the best video, because
you all wrote different answers. Someone liked tongue twisters, someone liked italics,
someone liked vocabulary games, someone liked dialogues, and so on .. To be honest, I was very
pleased with this result , because I prepared each task with enthusiasm and hoped that each task will be
interesting for you. Personally, I really liked the last task when you talked about your
country. This is how we all learned a little about your countries. Students from England,
from Algeria, from Argentina, from Brazil, from El Salvador, Greece, from Cyprus, from the Netherlands, from the USA, Japan, Syria and so on
took part in our marathon . Such is the geography! Well, now let's look at the most difficult moments of the marathon.
Day number five - negative sentences, "no" and "not". One question was particularly difficult. This one:
Were they in class yesterday? Now I specifically read it without intonation. Many of you answered,
"They were not in class yesterday." Or "No, they weren't." If it was text, it might be correct.
But you heard my question, and my question was: "Were they in class yesterday?"
Can you hear my intonation? Yes, here is day number three, intonation, and this lesson should havе helped
you with the correct answer ... Were they at the lesson yesterday? Here it is, the main word, the focus here, so the potential
answers "yes, at the lesson" or negative answer "no, not at the lesson". In the theatre. In the shop. In the restaurant.
No, not in class. We put "not" before the main word. Our question is - were they at the lesson or
not at the lesson? We show this with intonation. By the way, I forgot to say that the most difficult task
in this marathon was definitely video number three - intonation. And I understand why. Many of you
wrote to me that this was your first time working on Russian intonation. You sent me a lot of great
videos, and I tried to write you in the comments, somehow correct you, what needs to be done ...
But, of course, this is difficult to do in the comments. We work on intonation live, in the classroom.
And I thought it would be nice to organize a lesson or seminar on intonation. If you are
interested, write a comment "I want a lesson on intonation" and when I organize it, I'll let you know.
The next difficult part of the marathon is day six, double negation.
This example raised almost no questions. Who did you meet? With no one. I have
n't met anyone . I haven't met anyone. Here, almost everyone answered correctly,
no problem. We put "not" before the preposition. With whom? With no one. But for some reason the next question,
which is very similar to this one, raised a lot of questions. What concerts have you been to?
To which - here is also a pretext, the same as here, and we answer in absolutely the same way. On what? None.
What concerts have you been to? None. I haven't been to any concerts in 2020.
If we compare - absolutely similar structures, right? With whom? With no one. On what? None.
Hope this is clear. Next - day number nine. These were vocabulary riddles where you
guessed words, and this subject was the most difficult word. I was explaining what we needed when
my phone ran out of battery. We need this item here. What is it called in Russian?
I think that many have tried to google this word or look up in the dictionary. Correct answer: this is a charger
, or the colloquial version is charger. By the way, we knew this word in lesson number 5.
So, if you watched my course, you have known this word for a very, very long time, you may have
simply forgotten. And one last comment for today. Day number 10, numbers. The most difficult were
these two. Let's try to read them together. 912 - Hope you read it correctly. Not 919,
not 920, but 912. Hope you hear the difference. And this ... 10342. Not 9342, but ten thousand.
Hope you hear the difference. Well, that's probably all! Now let's congratulate the winners of the marathon together
. The winners are the most active participants in the marathon. I will repeat once again that in this marathon it
was not very important for me how many mistakes you made, and whether you made mistakes or not, because you all
have different levels of Russian. For some, the tasks were very easy, for others - difficult.
Someone just recently started to study Russian, someone has been studying it for a very long time. Therefore, as you
all saw, we received very different answers. I think it would be unfair to compare
students with different levels, and I immediately announced that the most active participants would be the winners,
because the goal of the marathon was to form a habit of practicing regularly. Yes, our goal
was to train for 21 days in a row. Here. I reviewed and re-read all your answers for a very long time,
I made such tables here with all the participants in the marathon, for a long time I counted
I made such tables here with all the participants in the marathon, for a long time I counted
who participated in how many days and published the answers, I double-checked it several times ... But nevertheless,
I am not a computer, so if I missed something or made a mistake somewhere, do not be offended!
But I tried to calculate everything as accurately as possible. Let's congratulate the winners. First, those who completed
twenty-one tasks, that is, one hundred percent. 21 tasks out of 21. There are two such
students - they are Molly and Phil. For you, one might say, a gold medal! Next ... five students ... No, six students who completed
20 out of 21 assignments which is also an excellent result. These are Rain, David, Marcos, Rami, Yoshihisa and Murad.
20 out of 21 - great! And finally, those who did sixteen, seventeen, eighteen or nineteen tasks -
that is, much more than half. These are Salvador, La Chica, Rena, Linda, Jermaine and David Mackenzie.
I also want to say thank you to Joanne, Ben, Anatoly, Roberto, Slavomir, Dave, Eva, Tanya and Azad for their
active participation in the marathon and wonderful tasks! I hope that I haven't forgotten anyone ... And now, taking this
opportunity, I want to say thank you to everyone who supported my project on ko-fi. During this marathon,
I received a lot of coffee from you, so I want to say thank you! Luciano, Rain, David, Molly,
Jouni, JoАnne, Tania, Yoshihisa, David, Clara, Philipe, Salvador, David again, Christopher
from Australia. Thank you so much for supporting the channel! Well, today is the last day of January. January
flew by very quickly (for me, at least). In January you were very active in the Russian
language, I hope this will help you to continue in the same spirit. Write what plans do you have for February,
for March ... Plans for your Russian, I mean. What are you planning to study? How do you plan to practice?
How often do you plan to study? I also remind you that if you are learning Russian
recently, that is, for several months, maybe half a year, I have a course for you. Course for
beginners. The link will be here and in the description. There you will find all the basic grammar and vocabulary
and communication ... - everything you need. If you like to practice systematically, regularly,
everything is already ready for you, so I am definitely waiting for you! But if this is already easy for you, you have already
gone through all this , you want to study further - perhaps you will be interested in my course on Patreon.
Let me remind you once again, if you want a lesson on intonation, if you are interested, write in the comments
"I want a lesson on intonation", and I will definitely invite you when I organize such a lesson.
Once again a big thank you to all the participants of the marathon, all the viewers. See you in the next video! Bye!
