I am a native speaker and I cannot believe how inconsistent Duolingo answers are. Sometimes they pick on the tiniest words like 一直 in "一直往前走". Now I type "one year" for 一年 and they do not accept it. Such answers are poor quality for foreign speakers.

he wants to buy a new fridge in one year.

He wants to buy a new refrigerator in one year.

next year or in a years time. in a year could mean during a year which could be any year which is about as vague as it gets

I used the official answer except with "one year" in lieu of "a year" and my answer was rejected. Please fix!

When does 想 mean "want" and when does it mean "would like"?

Perfect Chinese now. Duo is listening.

他一年後想買新冰箱 & 一年後他想買新冰箱 sound better.

I dislike in the new format that you cannot slide the answer panel. I want to see what mistake I have made.

I know each of these characters and the sound(s) they may make, but I could not for the life of me understand what she was saying. I don't know if my brain is struggling to keep up with faster speech, but I feel like there was no enunciation between each character for the entire duration of 想一年后。
