How to use "vehement" OR "vehemently" in a sentence?

Japanese..how do i use kizuku and kimeru in sentences?! i dont understand how to do that whole sentence with..?

• sentence within a sentence deal. i know basic sentences like ''kare wa itta to omoimasu'' and ''atarashii kutsu ga hoshii to itteimashita'' but how do i use it with other verbs? like kizuku and kimeru. to say, for ex, ''i realized that i lost my phone'' and ''i decided to go buy a sandwhich for lunch'' i dont understand.. also, how do you ask ''what do you think about ___?" ive heard ''nani wo omou'' and ''dou omou'' in songs and things, but i get confused. i always think , shouldnt it be ''nan to omou'' ? the lack of the particle to and the use of the particle wo threw me off. or, is to only used for specific things? i decided THAT such and such, i realized THAT such and such, i think THAT such and such, and other wise it wouldnt be necessary? so, ''i decided to go'' would be ''iku to kimemashita'' and 'what have you decided'' would be ''nani wo kimeta n desu ka'' gah im lost. please be detailed thanks!! and im only writing in romaji cuz yahoo always cuts off my japanese sentences

Say "--- ni tsuite dou omoimasuka?" >What do you think about Japan? nihon ni tsuite dou omoimasuka? >so, ''i decided to go'' would be ''iku to kimemashita'' and 'what have you decided'' would be ''nani wo kimeta n desu ka'' This is correct. >and im only writing in romaji cuz yahoo always cuts off my japanese sentences Insert breaks to prevent being cut off.
