هل كل هذه الجمل صحيحة ؟؟؟


we should appreciate their work to keep us safe .

we should appreciate their help to keep us safe .

we should appreciate their efforts to keep us safe .

we should appreciate their efforts to keep us safe
هى الادق

ولكن الثانية صحيحة

التوضيح

appreciate something that someone has done for you( effort-help--)
you are grateful to this person becusae of it

وعندما نريد ان نحول معنى الجملة الى طلب

نستخدم تركيبة
i would appreciate it if you could------
i would appreciate it if you could help me.

شكرا يا استاذ على هذه الإجابة الوافية بس هو الجملة الأولى تنفع ولا لأ ؟
