Phương pháp giải

Câu phức

Một câu phức bao gồm một mệnh đề độc lập và ít nhất một mệnh đề phụ thuộc.

Chúng ta sử dụng các liên từ phụ thuộc (after, before, when, as soon as, if, because, although, etc.) để nối các mệnh đề trong một câu phức.

Nếu mệnh đề phụ thuộc đứng trước, ta đặt dấu phẩy trước mệnh đề độc lập.
