🔰Present perfect continuous or present simple and continuous ?
الفرق بين المضارع التام المستمر و المضارع البسيط و المستمر


1⃣ How long? Present perfect continuous

We use a present perfect continuous to say how long a situation or action has continued up to now.
كما علمنا سابقاً أننا نستخدم المضارع التام المستمر للتعبير عن مدة حدوث الفعل من بدايته حتى الآن. قارن الأمثلة:

🤔Compare:

🔹It’s raining again.
◽It’s been raining since Christmas.
(Not It's raining since Christmas.)✘

🔹Are you learning English?
◽How long have you been learning English?
(Not How long are you learning English?)✘

🔹’I hear you’re working at Smiths.' ◽‘Yes, I've been working there for a month.’
(Not I’m working there for ...)✘

🔹I know her well.
◽I’ve known her for years.
(Not I know her for years.)✘

🔹My brother is a doctor.
◽How long has he been a doctor?
(Not How long is he a doctor?)✘

🤔Compare also:

🔹How long are you here for? (= until when; when are you leaving?)
◽How long have you been here for? (= since when; when did you arrive?)

2⃣ This is the first time, etc
إنها المرة الأولى، .. إلخ

We use a simple present perfect after this is the first time that... , it’s the second ... that... , and similar structures.
نستخدم الزمن المضارع التام البسيط بعد عبارة إنها المرة الأولى التي ...، هذه المرة الثانية ... و صيغ مشابهة لها:

✨This is the first time that I’ve heard her sing.
(Not This is the first time that I hear her sing.)✘
✨It’s the fifth time you've asked me the same question.
✨This is only the second opera I’ve ever seen.
