Present Perfect Continuous

Present perfect continuous digunakan untuk merujuk ke waktu yang tidak diketahui antara 'sekarang' dan 'sebelum sekarang'. Penutur memikirkan sesuatu yang berawal, tetapi mungkin tidak selesai dalam periode waktu tertentu. Penutur tertarik dengan proses dan hasil/akibat, dan proses ini mungkin masih berlanjut atau sudah selesai.

Kejadian yang terjadi di masa lalu dan masih terjadi di masa kini

She has been waiting for you all day (= dan dia masih menunggu sekarang).
I've been working on this report since eight o'clock this morning (= dan saya masih belum menyelesaikannya).
They have been travelling since last October (= dan mereka belum pulang).

Kejadian yang baru saja selesai, tetapi kita tertarik dengan hasil/akibatnya

She has been cooking since last night (= dan makanan di meja terlihat lezat).
It's been raining (= dan jalanan masih basah).
Someone's been eating my chips (= separuhnya telah habis).

Membentuk Present Perfect Continuous

Present perfect continuous tersusun dari dua unsur: present perfect dari kata kerja to be (have/has been) dan present participle dari kata kerja utama (kata dasar + ing).

Subjek has/have been kata dasar + ing
She has been swimming

Kalimat positif: She has been/She's been running.
Kalimat negatif: She hasn't been running.
Pertanyaan : Has she been running?
Pertanyaan negatif: Hasn't she been running?

Contoh: present perfect continuous, TO LIVE
Positif Negatif Pertanyaan
I have been living. I haven't been living. Have I been living?
You have been living. You haven't been living. Have you been living?
He, she, it has been living. He hasn't been living. Has she been living?
We have been living. We haven't been living. Have we been living?
You have been living. You haven't been living. Have you been living?

Kata kerja tanpa bentuk continuous
