Penjelasan:

Perbedaan antara present perfect tense dengan present perfect continuous tense adalah:

present perfect tense digunakan untuk sesuatu yang pada saat ini (yaitu pada saat kalimat tersebut diucapkan) dia sudah tuntas/selesai.

Sedangkan present perfect continuous digunakan untuk sesuatu yang sudah dimulai pada masa lampau, tapi masih berlangsung hingga saat ini (yaitu hingga saat kalimat tersebut diucapkan). Atau sesuatu yang baru saja selesai, tapi kita menaruh perhatian pada hasilnya.

Struktur present perfect tense:

(+) subjek + have/has + verb3 + objek/keterangan

(-) subjek + have not/has not + verb3 + objek/keterangan

(?) Have/Has + subjek + verb3 + objek/keterangan?

Struktur present perfect continuous:

(+) subjek + have been / has been + verb-ing + objek/keterangan

(-) subjek + have not been / has not been + verb-ing + objek/keterangan

(?) Have/has + subjek + been+ verb-ing + objek/keterangan?
