My Vacation to Colan

I´m cheking checking in at the airport for my trip to Colan. It´s in Piura, Peru. My suitcase isn´t heave heavy, so I don´t have problems in the airport. There are many Hotels, but I stay in my aunt´s house [ instead ]. The North Northern food is good, I can eat saltado al chabelo or ceviche. The weather is good [ as well ], It´s always sunny and hot there. You should use a t-shirt and sandals. While visiting Colan, I can swin on swim at the beach. Piura is an interesting place for know [ to explore ].

I capitalize "V" in vacation because, in English we usually capitalize the words in a title (but we do not capitalize "to", "and", "but" etc.)

"The Northern food" = "The food from the North"

Overall you did very well. One more thing I would point out, is you are using an accent ´ instead of an apostrophe ' . You are writing "my aunt´s house" instead of "my aunt's house".

I agree that “are you almost done with that?” Is a good way to say it. But they will respond “yes” or “no” If you want to know the amount of time, ask, “How much longer [do you think that] will take you?” So, for example: “Are you almost done writing that report?” — “Yeah, I’m almost done.” “How much longer do you think it will take you?” — “Oh, probably just a few more minnutes”

As a native speaker in the US, the words "occasionally", "sometimes", "not often", "rarely" seem most natural for what you want. For example, "I love cake, but I rarely eat it". "I occasionally go out and watch a movie. I would go more often, but it is so expensive." "Sometimes I put cream in my coffee, and sometimes I don't." "I don't study very often, but I always enjoy studying when I have the time." Note: rarely is less often than sometimes/not often/occasionally. So, "rarely" means "almost never". ------- As for the other words, I will try to help. "Chaotic" means completely confused and unorganized. "After the actor became famous, he became addicted to drugs, and his life was completely chaotic after that." It is similar to the word "haphazard". (Note: "chaos" is also used in an academic context called "Chaos Theory" which has a different meaning.) Erratic is also similar to chaotic and haphazard. It means random and unpredictable. For example, "Her mood is erratic. One moment she is happy, the next moment she is sad, and then angry, and then another moment passes, and she is laughing and smiling." Irregular means something is "not normal" or that it doesn't fit a pattern. Like irregular verbs in a language— they don't follow the pattern. The word "fitful" means something is interrupted by "fits". "I was trying to sleep, but the sleep was fitful" OR "I was trying to help, but the progress was fitful. People kept interrupting the progress." I should say "fitful" does seem to usually be used to talk about sleep. Also, the word fitful is rarely used. I am a native speaker and did not know what it meant.

88th day 2019

Nothing interesting today. I just want to build a plan for the weekend. Yesterday I saw a doctor who gave an injection into my joint and removed  stitches. So today [1] I want to have rest, practice English, and [2] go for a walk a little. Tomorrow I am going to resume working on my flat.

First off, this is well written. I have a couple notes for you, that I hope will help.

[1] I would recommend, "I want to get some rest."

[2] "Go for a little walk a little."

Adjectives

Hi, yhere

Do you say “Short high noises” or “Short, high noises”? And “a call consiting of repeated light tremulous sounds” or “a call consisting of repeated, light, tremulous”?

With or without the commas?

It depends on what you want to say.
For example, if you say "the dog had small, black spots," that means, "the spots are small and black."
However, if you say, "the dog has small black spots," that means "the black spots are small."

When you use the comma, the adjectives both describe the noun equally. If you do not use a comma, that means the adjective closest to the noun is more important. It becomes part of the noun.

For example, we write "look at this beautiful classic car," because we mean it is a "classic car" that is "beautiful." So, in this case, "classic car" acts like a noun.

But if I write, "She is a friendly, confident woman," then I mean, "the woman is friendly, and she is also confident."

So if you can put "and" between the adjectives, then use a comma.

In this instance, I would recommend you keep the commas.

If you want to use a phrase to describe your schedule as busy, you could say: "My schedule is always jam packed".

Yes, they are well constructed sentences, and they sound natural. Though, these would likely be said in a very serious way. You might hear these sentences in a confrontation, or an argument.
