I know it's a really common one, but, "Everybody is a genius, but if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid."

Being Independent

Independence is a lesson that every teenager have to learn.Independence is not just being able to do things on your own, it is also thinking independently and thinking for yourself without harming others, taking care of yourself and the people around you, and becoming a true individual.
As we grow up, we will leave home to study or work while still in our teens. To be independent,we are supposed to do thing on our own first. It is necessary for us to master some fundamental life skills such as cooking, laundry, etc.Then, becoming a independent thinker tends to make it possible for us to solve some difficulties without a (a hand OR support) extended from our parents. Futhermore, we will have our own understanding and insight about the world with independent thinking. Finally, taking care of the people around us is what helps us to be more independent. Only when we are capable being in charge of our lives and put ourselves in the place of other people, can we be named as real independent thinker.
God helps those who help themselves. He who can become independent has the whole world with him; he who cannot walks a long way.

______________________________

Some notes:

- There's nothing wrong with "washing the clothes," and if you say it, people will understand it. But a native speaker will never say, "washing the clothes." We say "laundry," or, "doing laundry."

-"Become an independent thinker tends to make it possible for us..." Okay, so all sentences have AT LEAST two parts:  a subject and a verb. (Many sentences have many more parts, but in order to be a sentence, there must be a subject and a verb). The verb is the action word, and the subject is the thing that does the action. In this instance, the verb is "tends." So what is the subject? What "tends"? In this case, it's the entire concept of "becoming an independent thinker," is the subject. Because, "become" is part of the subject, not the main verb, you need to put the "ing" ending on it to make it more of a noun. Now, "becoming" is a THING that you can do.

-When using the phrase, " a hand," everyone knows what it means, and you don't need to say, "of support."

-The way we express "charge" can be weird in English. But ultimately, we usually only say "charge" followed by the word, "in." You refer to things as being IN the CHARGE of whoever controls them. So, for example: "Kelly is in charge of planning." Or, "We're in charge of Management." You could also say something like, "I am in Sarah's charge," or "The children are in the nanny's charge." But those sound formal and outdated. We don't usually use that verbiage anymore, but it's still correct.

-Another example of English being weird: "Only when we ____, can we ____." I know that makes no sense, and I don't know what grammar rules enforce this, but this is the only way we say it. When you start a sentence with "Only when (subject)..." you ALWAYS end with "can (subject)..." or, "will (subject)..." 

-Last note: Remember that commas (,) go at the end of the word before them, then a space, and then the next word. Also, periods (.) go at the end of every sentence, then a space, then the first letter of the next sentence is capital. 

Overall, this is amazingly well done! You use some fantastic vocabulary, and there are some small, subtle errors, but I understood everything you said! It looks like you're doing really well! Good luck! :)

I think the best option for you is, "Over the period of 2000 to 2010" Also, "over the period" and "during the period" are almost the same, and the difference between them is very subtle, and I'm not sure which one is better to use without knowing the rest of the sentence. Also, while there's nothing wrong with "over the period" or "during the period," we normally won't say that. We might say it if we're trying to reach a word count on an essay, so it makes sense to say it for the IELTS, but in conversation, we would just say, "From 2000 to 2010." It's also perfectly acceptable to say this in an essay. I hope this helped. :)

I agree with Arianna. The most natural way to say this is, "This exercise must bee done in groups of three, instead of in pairs," or, "For this exercise, you will need to work in threes, instead of pairs."

As a native speaker, this sentence didn't make any sense to me at first. Amnesty means pardon or forgiveness, usually of a crime, and I've never seen amnesty used in this way. But I copied the quote, looked it up on Google, and found the full article. In that article, they use the term, "gun amnesty." "Gun amnesty" is something that some governments will do to try to reduce the number of illegal guns in their area. They will announce that, for a period of time, citizens can give their illegal weapons to the police, and they will be granted amnesty (they will not face legal consequences for having that weapon). I hope this helps! :)

This is all fine where grammar is concerned, and most of it sounds relatively natural, but here's how I (native speaker) would say this: I'd like to make a request. I would be so grateful if you could renew our production entry list of AAA. Unfortunately, the existing list is not good. Would you be able to renew it? If renewal is possible, please use the attached file. I hope you will consider my request.

Encouraging new ideas

Today's activity was to write a memo to the head of the organization I work for, suggesting ways to encourage initiative among employees.
Here we go!

To: Zander Cobain, Head of IT Solutions
From: Plínio Almeida, Senior Software Engineer
Date: April 5, 2016
Subject: Encouraging new ideas

Dear Mr. Cobain,
I have been thinking about it for some time and I decided to bring this subject to you, once I realized we are losing great opportunities to improve our methodology and our productivity.
Our team is comprised of a lot of experienced professionals, and our current framework is slowing us down. Through some informal conversations during our lunch breaks, I noticed that everyone is disposed to help, and everybody has excellent ideas, but we don't have a way to discuss and implement them. In addiction to that, there's too much bureaucracy in our communication system. Because of this, even small decisions have to be bought to you directly.
Of course our methodology allows you to have the full control of the decisions but I believe we can find a way to balance some productivity with it.
My proposal is for the company to encourage the employees to take small decisions. In that case, we could have monthly meetings to discuss them and see which mistakes were made. We should also schedule some hours a week to brainstorm about bigger decisions. In that case, the final word in the subjects that matter would still be yours, but you could start from something that we've already thought though. I am willing to discuss this subject with you, at your convenience.
Best regards.

"please" doesn't need a capital "P." Other than that, the grammar is correct. :)
