الجملة الرابعة فى التصحيح تمشى will run
عشان لو رجعنا للكتاب المدرسة SB page 97
Review E -Ex 3هتلاقوا الجملة دى
English will be spoken by half the world population by 2050
this is prediction without evidence
طيب وشوفوا مدى تطابق الجملة دى مع السؤال الرابع فى التصحيح لامتحان اليوم
-By 2020, eco -friendly cars run or will have run on water and sunshine
ازاااااااااااى تكون الجملة دى future perfect وهي عبارة عن تنبؤ بدون دليل
اعتقد انها هتمشى فى التصحيح will run or will have run

Sorry Mr. Gwad but
Future perfect has two forms:
a( will have + past participle
b) be going to have + p.p
so this reveals that there is no use in this tense concerning evidence or something else
The use of this tense is
a) an action in the future before another one

You can call me at work at 8am. I will have arrived at the office by 8
b) it also expresses past in the future
When you arrive, the train will have left

According to the sentence in the exam
I see it is future perfect will have run
However, the sentence in the book talks about a fact that will happen in the future
English was spoken, is spoken, will be spoken . Speaking in English or the use of English will never come to an end



PLEASE ACCEPT MY LITTLE COMMENT AND THANKS FOR YOUR PATIENCE
