fFirst day of intenseively learning eEnglish

Today is athe first day of my little challenge.

I am going to improve my English skills from B1 to C1 forin 60 days.

Today I was practiceing my grammar, lexisvocabulary, listening, reading and speaking.

The part I'm most comfortable part of with is listening.

I was listened to Luke's English Podcast.

You could say, "I was listening..." but I think it's more natural to use the simple past tense, "listened," in this context.

He was talkinged about using -ise and -ize.

While he was talking about that, he telling theold a story from his childhood about how native speakers sometimes misunderstand each other.

And how native speakers sometimes misuderstand each other.

I think what you're trying to say sounds better if you combine this sentence with the one above.

He tolsaid that when he was child, he understanood it like as "Knowledge is Ppower.

When he was on theat his friend's birthday party, they were at McDonald's, and the employees invited him and his friend to the kitchen.

They were in the Macdonald's.

Where the employees invited him and his friend to the kitchen.

And told 'emThey said, "There is a walk-in-freezer," but he understood it lika as "walking freezer" so he was wonder, wed, "Where's its legs?"

fMy First dDay of iIntense learning englishEnglish Study

'My First Day of Studying English Intensely' or just 'My First Day of Intense Study' also work!

Today is athe first day of my little challenge.

Mostly correct, but you can also do 'Today is the first day of my little challenge:' since the following sentence is what the challenge is. As in 'Today is the first day of my little challenge: I am going to improve my English...'

I am going to improve my English skills from B1 to C1 forin 60 days.

'in' = short for 'WITHin'. Since you're talking about a challenge to reach a specific point, this implies a deadline. The challenge is that you are going to accomplish C1 in 60 days.

If the goal of the challenge is actually just to consistently study for 60 days, then you can just say: "Today is the start of my little challenge. I am going to study English for 60 days." Mentioning wanting to also get from B1 to C1 would sound odd here, since the expectation is that you are defining the goal of the challenge and that isn't it. It could be mentioned as an incidental desire later on on the paragraph if you wanted, though.

Today I was practice my grammar, lexisvocabulary(?), listening, reading and speaking.

I don't know what 'lexis' is. I don't think it's a real word.

A 'lexicon' is a word for a dictionary, but you're talking about non-tangible studying items here, so it wouldn't fit. I went with 'vocabulary' instead, since it fits the theme.

Otherwise, well done!

The part I'm most comfortable part of with is listening.

Or 'The easiest part is...'

I was listening to Luke's English Podcast.

While he was talking about that, he was also telling thea story from his childhood.

Andbout how native speakers sometimes misunderstand each other.

For example, "Knowledge is power."

Francis Bacon".

Seem more natural to write it '"Knowledge is power." -Francis Bacon.' or '"Knowledge is power", as said by Francis Bacon...' or something like that, but I don't think this is exactly wrong, except that only the actual quote gets the quotation marks.

If you're quoting the podcast, then "'Knowledge is power', - Francis Bacon." is better. Single (') for a quote inside a quote.

He tolsaid that when he was child he understanood it like a, "Knowledge is Ppower.

He gave an another example, also from his childhood.

When he was on theat a friend's birthday party.

They were in the Macda McDonald's.

I understand the confusion here. '...the McDonald's...' is very colloquial when used without a prior introduction to a specific McDonald's (Grammar: 'a' - any general McDonald's, 'the' - this one specific McDonald's that we both know all the details of and can picture accurately). People can sometimes use it this way in the US because it used to be generally understood that every town has at least one McDonald's and they are probably talking about that specific local McDonald's (that everyone knows). 'We went to the McDonald's' = 'We went to our local McDonald's, specifically the one everyone in town goes to', but it's still not grammatically correct in this case. '...a McDonald's...' is better.

WTherey were in a McDonald's, and the employees invited him and his friend to the kitchen.

Connecting it with the previous sentence sounds more natural!

AndThey told 'them, "TOver there is walk-in-fthe Walk In Freezer" h. He understood it lika ae, "walking freezer", so he washad to wonder, where' was its legs?

fFirst dDay of iIntense learning englishEnglish Learning

Today is athe first day of my little challenge.

The is used to refer to something specific, while a is used for things that are not specific. "First day of my challenge" is specific

I am going to improve my English skills from B1 to C1 for 60 days.

We need the verb "to be" (in this sentence am) to form a complete action

Today I was practiced my grammar, lexis, listening, reading and speaking.

If the action happened in the past and is complete we add -ed to the verb (practice) and do not need the verb "to be" (was)

I have been doing itpracticed for 5 or 6 hours.

"I have been doing it..." could be right if the action is still happening. To follow the structure of the last sentence we put the action in the past

TheI feel most comfortable part of it iswith the listening part.

I was listened to Luke's English Podcast.

add -ed to put the action in the past

He was talkinged about using -ise and -ize.

While he was talkinged about that he telling theold a story from his childhood.

Aand about how native speakers sometimes misunderstand each other.

For example "Kthe phrase "knowledge is power."

by Francis Bacon".

He tolsaid that when he was a child he understanood it like as "Kknowledge is Ppower...

France is bacon"."

It' was really funny.

Is is present tense, was is past tense

He gave an another example also from his childhood.

When he was on theat a friend's birthday party.

We use "a" instead of "the" because it is not a specific friend, we don't know who it is

Tthey werent in the Macdto a McDonald's.

Where tThe employees invited him and his friend into the kitchen.

AndThey told 'them "Tthere iwas walk-in-freezer", but he understood it lika as "walking freezer" so he was wonder, ed "where' was its legs?"

This is a story that happened in the past so change it to past tense
