This is not a piece of advice to you I'm talking to myself for my practice of writing skills.
I suppose concerning punctuation the grammar book would look like powerful only within one sentence. it'd be utterly powerless within the bunch of sentences. because the influence of punctuation would reach to the unexpected distant sentence under the help of GT. It'd be good for you to study grammar but concerning punctuation I suppose the harder you'd study the grammar the more you'd suffer from neurosis. I'd recommend Initially punctuation training with GT then leaning grammar after it. GT'd seem to prefer the wild sentences without punctuation marks. I suppose you'd be easily able to grasp that comma'd be a pebble-stone on the highway for GT who can translate a book in a several second. if you hesitate to put a comma or not it'd all be needless.even if grammatically necessary it'd needless. comma which'd be necessary only for arranging of human brain are unnecessary for GT. for quotation mark use apostrophe and eliminate all comma and period then the sentence put into GT. the part of the sentence where make no sense might need comma/period or semi-colon. some cases'd need remaking of the sentences. these'd be one of GT's punctuation rule. we can't lose the interest in the articles which reporters are writing. they 're good/useful/effective text-book for our learning writing skills.
I'm sorry to say these matter along with knowing reporters' sufferings of the restriction of time. 'kimono' , 'comma and period' , ' article' (in the 'question box of English') ,please try these.
