"Please take a shower immediately."
The てform, among other things is used to convey requests along with ください. So please take a shower - シャワーをあびてください. But I take a shower will take the simple ますstem, シャワーをあびます。
How come the adverb comes before the direct object in this sentence, but in that other exercise about reading a lot of books it comes before the verb? How do you know where to put the adverb?
It is my understanding that due to the particles marking what is what, you can put the words with particles after them in any order
直ぐにシャワーを浴びってください I could be wrong but, could it be that Duo isn't taking some answer in kanji? I could also just be giving the wrong answer but it doesn't seem that way. I'm confused. I wish Duo would support learning Kanji more.
