what is usage of `at`.

At implies a particular point in space or time. It is very specific. "She was at the police station at 2:30 AM when the call came in." "He was at his job in the factory." "They were in the water at dawn."

but it doesn't work with eat if you add ed to eat it will be eated witch doesn't make sence the way you wright eat in the past is ate.

this is an irregular... you just have to learn these, in all languages.

Hi, Is there a video on past continuous, past perfect on Khan academy? Thanks in advance.🤗

You can learn about those in the section titled “Verb aspect: simple, progressive, and perfect”. There’s also the search function at the top of all screens in Khan Academy which you can use to look up any topic in which you are interested.

in 1:50, he says: "and most of the time when you wanna form the past tense out of a word..." WHY MOST OF THE TIME? Could someone give me an example?

OK. Here's an example. "She walks." (present). "She walked." (past). "They run." (present). "They ran." (past).

Can't you say "I was walking to the to the moon" instead?

Yes! What you just suggested is called progressive past tense. You could say "I walked to the moon" or "I was walking to the moon" depending on the order of events or subtle implications you are hoping to incorporate in the sentence.

What are energy points for?

Energy points are for your convenience, so that you can keep track of your progress. You can't turn them in down at the gas station for a chili dog.

  It is just an example of past tense! I mean, if he flew to the moon he could be able to walk on it, but that's not what he means. ❤️ヾ(￣▽￣) Bye~Bye~

Video transcript

- [Voiceover] Hello, friends, and welcome to the distant past, because today we're talking about the past tense, which refers to stuff that has already happened. There are many ways to form the past tense, but for now I just wanna focus on the basic version, which is just adding "-ed". So if you take a word like "walk" as in, "I walk to the store," no, not the store, to the moon. I'm going to the moon on foot, try and stop me. That's in the present tense, but if I wanted to put that in the past, I would say, "I walked to the moon." I've got very strong legs and good shoes. So this sentence is happening now. It's the present. This sentence happened earlier. It's the past. SO, the simplest way to figure out whether or not something is in the past tense or if you want to put something in the past tense, is this thing, this "ed" ending. So you go from "walk" to "walked", "talk" to "talked", "sneeze" to "sneezed", "jump" to "jumped" and "open" to "opened" So, if it doesn't end with with an "e", you add an "ed". If it does end with an "e", you just add the "d". That's how to form the past tense. That's what the past tense does. It's stuff that's already happened, and most of the time when you wanna form the past tense out of a word, you just add "ed". You can learn anything. David, out.
