这里为什么要用remaining?不是该用remained么？

这里为什么要用remaining?不是该用remained么？i feel upset,there are so many troublesome problems (remaining) to be settle.

打错了吧，最后应该是settled
懂非谓语吗？主动用现在分词，被动用过去分词
remain是不及物动词，不及物动词没有被动语态，所以只有主动语态，只能用现在分词
关于主动和被动的判断，首先要找逻辑主语
There are many students playing on the playground.
play的逻辑主语是students，主动关系，students play
There are many flowers placed on the playground.
place在这里作动词，是摆放的意思，逻辑主语是flowers，flowers are placed，被动关系

not like that. remained is the past tense of the verb. remain.not the -ed form adj. of remain. only remaining is the right adj. form of remain remained只是remain的过去式，它只是一个动词。 remaining才是remain的形容词形式。
