present continuos
يدل على فعل يحدث الان ويممكننا رؤيتة او سماعة او ادراكة ويمكن التعرف علية بهذة الدلائل( now,at the moment,at present)
مثال على ذلك:she is watching TV now,,,,,or they are waiting now
يجب اضافة ingللفعل الاصلي(watch,wait)معis,are,الافعال المساعدة
ام صيغة السؤال كالتالي(is she playing football?)يقدم الفعل المساعد على الفعل
اما النفي يوضعnotبعد الفعل المساعد(is, am ,are)مثال:she is not playing football
........................................ ........................................ .........
present perfect
يدل على حدوث الفعل قبل وقت قصير ولا تزال اثارة حتى الان ويمكن التعرف عليةبهذة الدلائل(already,just, since,for)
يستخدمhave,hasبعد الفاعل ويجب تصريف الفعل الى التصريف الثالث(p.p)مثال: I have waited for along time,he has just gone
ملاحظة: has تستخدم مع she,he,itاماhaveتستخدم معthey,we,am,you
صيغة السؤال:have you posted it?يستخدم الفعل المساعدhas, haveقبل الفعل.
في حالة النفي:يوضع notبعد الفاعل مثال:they have not waited him
........................................ ........................................ ..............
present perfect continuous
we use the present perfect continuous for an activity that has recently stopped or just stopped
نستطيع ان نميز بينهم (been)مثال:it has been raining for tow hours
........................................ ....................................

فيه حالات معينه يفضل فيها استخداام المضارع المستمرر وحالات ثاانيه يفضل فيها استخدام المضاار البسط
وانا جبت لكـ نسخه بسيطه من هالحالات ........

Often there is very little difference between the present perfect simple and the present perfect continuous. In many cases, both are equally acceptable.

•They've been working here for a long time but Andy has worked here for even longer.
•I've lived here for 10 years and she has been living here for 12 years.
To emphasize the action, we use the continuous form.

•We've been working really hard for a couple of months.
•She's been having a hard time.
To emphasize the result of the action, we use the simple form.

•I've made fifteen phone calls this morning.
•He's written a very good report.
Look at the difference in these examples.

•I've been reading this book for two months but I've only read half of it. It's very difficult to read.
•She's been trying to convince him for 20 minutes but she hasn't managed to yet.
•They've been talking about this for month and they still haven't found a solution.
When an action is finished and you can see the results, use the continuous form.

•The phone bill is enormous. You've been calling your boyfriend in Australia, haven't you?
•You're red in the face. Have you been running?
When you use the words 'ever' or 'never', use the simple form.

•I don't know them. I've never met them.
•Have you ever heard anything so strange in your life
