Usually it goes like this: (time) + (place) + subject/topic + (time) + (place) + object + verb. Examples: 今日私は食堂でカレーライスを食べました。 昨日italkiで美しいフィリピン人の質問を答えた。- Note that in this sentence I omitted the subject (私) which is a common practise in Japanese language. However, in Japanese grammar the particles (は、が、を etc.) are more important than the word order, so sometimes you will see sentences with different structure (the only certain thing is that the verb will always stay at the very end of the sentence).

Thank you so much!! now everything looks clear to me. and is there any specific word order in a japanese sentence construction? (e.g topic + relative/ specific time + place + verb, etc ??

"Suru" (or "shimasu" in official situations) is a Japanese version of the verb "to do", "shite iru" (or "shite imasu") is a Japanese present continuous - "(am) doing"
