Answer 3

现在完成时：过去一直到现在都在做这件事，且这件事到现在已经完成了，也就是说这动作已经截止了。没持续。

现在完成时;
说明以上这动作还在持续着。

现在完成时have/has+动词分词

现在完成进行时have/has
been
doing

语法在于动词的时态的变化有区别而已

Answer 4

说有时说不清，给你个例子吧

I
have
been
learning
einglish
for
three
years.意思是，我学英语已经三年了（注意，现在还一直在学，不仅强调学了三年，而且强调现在的状态）

I
have
learned
einglish
for
three
years.意思是，我学英语已经三年了（注意，这个只是说已经学了三年，但现在是否在学不清楚，也就是说现在完成时只强调已完成的动作，并不强调主语现在的状态，而现在完成进行时则强调）

I
had
learned
einglish
for
three
years.意思是，我曾经学英语学了三年（注意，这个是说曾经学了三年，但现在不学了）

总的来说，现在完成时只强调已完成的动作
，不强调现在的状态，而现在完成进行时不仅强调所完成，还强调现在的状态，在句子中应用时就看你主语的状态了，另外上面还附了过去完成时和二者的不同，你可以对比一下
