1. because => that

do khúc đầu có "the reason" nghĩa là "lí do" nên phía sau có because là dư => bỏ because thay bằng that

2. she was sick => her sickness

vì due to + V_ing/N nên phải đổi mệnh đề she was sick thành danh từ là sickness

3. As of => Because of

As of: kể từ lúc nào đó => kh hợp nghĩa => đổi thành because of + V_ing/N

4. Because of => Because

Because of + V_ing/N = Because + clause

phía sau là clause nên kh thể dùng because of => đổi thành because

5. thanks to => because

thanks to + V_ing/N nma phía sau là clause nên phải đổi thành because
