It should have a similar subject with regard to anto the essay title.

Or: "It should be a similar subject to the essay title"

Readers always have to find it in the introduction as a rule towards the end.

It should be an idea that can be developed and added on and then (do I need add here ‘should be’ before ‘mentioned’) mentioned in the conclusion again.

don't have to :)

Three key aspects of thesis are: structure, cohesion and the logical development of the idea.

Without it, understanding of the text will be complicated, because this aspects helps to focus and control main idea, and keep on the track.

"keep on track" is a saying, so you don't need "the".

It should be something wthat the author wants to achieve, some kind of unique thought which will be discussed by audience.

That is the reason why writing a thesis statement can be really challenging process.

Sometimes after writing two sentences in a main body of essay, students start thinking that they want to change a concept, because they started giving arguments for another question.

Just be prepared rewrite your thesis statement several times before you get what you want and do not forget about powerful words.

I hear that a poor thesis statement is a paraphrased essay title.

It is good if thesis will thesis contains balance between generality and specificity, it does not have to be too complicated.

or: "it is good if your thesis will contain a balance".

But, I don't think the word "will" is necessary.

What is a thesis statement and how do I write itone?

It should have similar subject with regard toaddress the same subject as an essay's title.

Readers always have to find it in introduction, and it is—as a rule —towards the end.

This sentence is kind of odd, as it implies that *readers* have a duty to track down the thesis sentence, rather than the author having a duty to make it clear.

"As a rule, a thesis statement is found toward the end of the introduction, and should be clear and obvious to the reader."
or
"Readers should be able to easily identify the thesis statement, which is typically located at the end of the introduction"

It should be an idea that can be developed and added on to and then (do I need add here ‘should be’ before ‘mentioned’) mentioned again in the conclusion again.

You don't need "should be" before "mentioned".

This sentence (with the correction works), but sounds fairly informal (especially with "added on to"). I might phrase it as two sentences like this:

"It should present an idea that can be further developed and supported throughout the essay. At the end, the conclusion should come back to and reiterate the thesis statement."

The three key aspects of a thesis are: structure, cohesion and the logical development of an idea.

We typically include "the" here because the implication is that you are listing all the key aspects (and there are only three). If you wanted to say something that meant "There are many important aspects, but three important ones are", then I'd say "Three of the most important aspects of a thesis are".

The colon ':' after are is not wrong, but it is a little unnatural.

Without it understanding of the text will be complicated, because this aspectsa thesis statement, it will be difficult for a reader to understand the text, because it helps to focus and controllarify the main idea, and keep on the essay on track.

As I said, a thesis statement cannot be just be a fact.

"As I said" sounds a little bit aggressive, especially in academic writing. I'd probably say "As mentioned above" or "To reiterate". Also, maybe this is just a change you made while writing this, but you don't really say anything similar in previous sentences, so it may be better to remove "As I said" entirely and just use "A thesis statement cannot be a fact"

It should be somethexplaing what the author wants to achieve, some kind of unique thought which will be discussed by; that is, it should express a unique perspective that will be presented to the audience.

That's the reason why writing a thesis statement can be really challenging process.

This sentence is a little informal for academic writing; I'd probably say something more like "For this reason, writing a thesis statement can be a very challenging process."

Just bBe prepared rewrite your thesis statement several times before you get what you wantare happy with the results, and do not forget aboutto use powerful words.

"powerful words" is not very clear here, so for an academic paper I'd make this a little more precise.

Removing "Just" makes your statement more emphatic and decisive, which is better for academic writing. If you are writing more casually, like in a document to help students learn about writing thesis statements, then keeping "Just" is fine and can soften it a little bit.

By using evaluating language remember that itRemember that your language should be more academic and not too informal.

I'm not entirely sure what you mean here, so this is my best guess to rewrite it to be clearer.

I've heard that poor thesis statement iss are just a paraphrase of the essay's title.

Using "I've heard" in this is not consistent with the style you've had for the rest of this document. It suggests you're no longer giving reliable information, but are instead simply reporting rumors you've heard.

Better phrasing would be "Bad thesis statements are often just paraphrases of the essay's title".

It is good ifdeally, a thesis will containstrike a balance between generality and specificity, i. It does not have to be too complicated.

This is a suggestion to help simplify.

It should be an idea that can be developed and, added on, and then (do I need add here ‘should be’ before ‘mentioned’) mentioned in the conclusion again.

You do not need to add another should because your linking words, "and," "then," make it cohesive.

T(The) three key aspects of a thesis are: structure, cohesion and the logical development of idea.
