[m_d10]

I expect my brother ............a doctor. he is very clever
( is going to be - will be - is being - will have been )

هذه الجملة من كتاب التدريبات (Sec 3 WB page 2) و هذا رد موقع Longman علي سؤال حضرتك :
This is talking about my prediction based on my knowledge of his work. Will is the preferred future form

طيب حضرتك فى جمله فى كتاب The Best فى الشرح بتقول
my brother works hard, he is going to get high marks

يعنى هذه الجمله خاطئه أم التنبؤ بدليل مع الظواهر فقط
