Kajuthapa, There are a number of errors in your essay that need to be corrected. Kindly refer to my suggestions below:
I totally agree with fact that computers were first invented to make our life happier.
- While you present some very good points in this paragraph, it would be advisable for you to restate the thesis prompt prior to your point of view on the issue. That way the reader has an idea about what the discussion will be about and where the talk stems from.Actually, this is the only part of your previous paragraph that fits as the introduction to the essay. The succeeding paragraph should have been a part of the body.The body of your essay lacks development and only deals with one portion of the prompt. The part about making us more productive. You could have lengthened and strengthened your discussion by also tacking the second and third part about becoming less happy and more stupid. By discussing all three aspects, you will be able to present your position about computers being invented to make our lives easier and also counter the argument by saying that in the process of making us more productive, computers have also made people happier and more intelligent due to the ease of access to information.
Those are just some of my suggestions that I feel can help improve the over all content of your essay. While I could correct the grammar errors for you now, I always point out the problems with the body of the essay first and opt to correct that first because your grammar errors may lessen or increase depending upon how you revise the essay :-) I am looking forward to reading your revised essay if you choose to show us a new version :-)
