请问大家：我要说那堆水果是苹果~
我应该说 the fruit is / are apples ?!
language 是 U、trouble 是 C/U..
我该讲language is trouble /language is a trouble ?!

That is an apple; those are apples第二句话你想说什么？？？

第二句大概是想说语言很麻烦...

是的，学语言很麻烦..

they're both incorrect.you need to put on more details for it, such aslearning a new language is difficultor

学语言很麻烦的主词是[学]...

for a person who is not gifted at language learning,passing English test on the advanced level canbe very difficult.trouble 一般而言不会用在这样的内容

Thanks a lot！!

language is troublesome也未尝不可，后面用形容词就可以了。但是常见的说法是(some) troublesome language差别在于，并不是整个语言都很麻烦，而是有部分语言在使用上很麻烦。例如道歉，求爱，讽刺等等。
