 Caption: Hello everyone! Today is January 18th, and this is the eighteenth day of our
Russian 2021 marathon . Today we have a very fun task: we will try to say Russian
tongue twisters. What are tongue twisters? These are phrases that
need to be spoken quickly, but it's usually difficult. "Soon" means "quickly" and "talk ..." - to speak
quickly. Tongue Twisters. Today we will try to read and repeat three Russian tongue twisters.
The first tongue twister works out the sounds s and sh. Let's read it slowly: Sasha was walking along the highway. Sasha is
a name, a female name (and a male one too, but here it is a girl because she was walking)
And the highway is a big road. Sasha was walking along the highway.
Try to read slowly and then quickly: Sasha was walking along the highway, Sasha was walking
along the highway. Try to repeat a few times and read as quickly as possible,
but control the sounds s - sh. Be careful! Number two is a tongue twister for the sounds d - t and r.
Let's read slowly: there is grass in the yard, firewood on the grass. Let me explain what this
means. The yard is the place in front of the house. Where? There is grass in the yard. There is firewood on the grass.
Let's read it slowly again: there is grass in the yard, firewood on the grass. Now let's try quickly: there is grass
in the yard , firewood on the grass. I don't know about you, but it's hard for me. And number
three is my favorite one, for r - l sounds. This tongue twister is much longer, there are four
lines, but today we will only read one: Karl stole corals from Klara. Karl and Klara are
names: Karl is a man, Klara is a woman. What did Karl do? He stole, that is, he took it without asking, took it
illegally ... what? he stole the corals ... from whom? Clara's. Let's read it again: Karl stole the corals from Clara.
Let's try faster, although it's very difficult (for me, at least):
Karl stole the corals from Clara.  Well, let's read
all three again. Sasha was walking along the highway. Grass in the yard, firewood on the grass.
Karl stole the corals from Clara.
Well, I wish you the best of luck and I look forward to your audio and video. Here,
unfortunately, it is useless to write comments. Please record an audio or video, I am
very interested to listen! I am waiting for them in our Facebook group! Good luck and see you tomorrow!
