等我試下簡單 D 解釋你個問題。
首先，你的意思是個問題存在很久，還未解決，那便不應用 SOLVE。況且，你用 個 SOLVE 也用錯了。 the problem has been solving for a long time 這句錯。PROBLEM 被 SOLVE 不可用 ACTIVE VOICE，一定要 PASSIVE，個問題不會自己解決自己，一定要是其他人去解決。 你寫的那句是用了 ACTIVE VOICE， 個 PASSIVE 是
The problem has been ( being solved) for a long time. 不過還是錯，無人會這樣說。而應寫成：
The government has been trying to solve the problem for a long time.
第二，CONFUSE 是使人混亂，混淆。你的意思是困擾，應用 DISTURB， PERTURB。
The problem has been disturbing/perturbing the government for a long time.
其實你好 CONFUSED， 因你不明白 PERFECT TENSE 的用法。
HAS ＋ past participle
HAS 後面的 VERB 一定要用 past participle
所以，只有 HAS BEEN， 無 HAS BEING
CONTINUOUS 是加在 BEEN 後面，所以是
HAS BEEN CONFUSING／DISTURBING／PERTURBING
FOR A LONG TIME 多數用 PERFECT CONTINUOUS
has been confused 是 PASSIVE， HAS BEEN CONFUSING 是 ACTIVE
present prefect tense ＝ HAS CONFUSED ，
但不應和 for a long time 一起用。可用
HAS ALWAYS CONFUSED
>>present prefect continuous tense + passive 要點寫???
HAS BEEN BEING SOLVED
但要小心，不用好過用，因這個 TENSE 的意思很怪， PASSIVE 很少用 CONTINUOUS， ACTIVE 就會，意思是人們一直想解決那些問題，但調返轉頭個問題解決便是解決，不會一直解決緊，其他也要看個動詞，大部份動詞 PASSIVE 用 CONTINUOUS 都行不通。
希望你明白啦。

最後， 應用HAS BEEN SOLVED 或 HAS BEEN SOLVING。The problem has been solved.The government has been solving the problem.The government has been trying to solve the problem. 呢句最好，是你的原意。
