Remember, forget, and stop, where the choice changes the meaning.
Why you specifically
Một số động từ trong tiếng Anh có thể đi với cả to-infinitive và gerund, nhưng nghĩa sẽ thay đổi. Với remember, forget và stop, không chỉ là chọn cấu trúc đúng; chính dạng theo sau động từ làm thay đổi ý. Remember + to-infinitive thường có nghĩa là “không quên làm việc gì đó”. Remember + gerund có nghĩa là “có ký ức về việc đã xảy ra”. Forget cũng có sự đối lập tương tự: forget to do = quên nên không làm; forget doing = không còn nhớ là mình đã làm. Stop + to-infinitive nghĩa là “dừng lại để làm việc khác”, còn stop + gerund nghĩa là “ngừng hẳn một thói quen hay hoạt động”. Điểm này khác với verb-plus-infinitive như want to do, và verb-plus-gerund như enjoy doing, vì ở đó lựa chọn chủ yếu là cấu trúc cố định; còn ở đây lựa chọn làm đổi nghĩa. Người học Việt hay nhầm vì trong tiếng Việt nhiều khi chỉ dùng một mẫu chung như “nhớ/quên/dừng + V”, nhưng tiếng Anh tách nghĩa rất rõ.
The rule
Some verbs can take both a to-infinitive and a gerund, but the meaning changes. With remember, forget, and stop, the form after the verb is not just grammar; it changes the message. Remember + to-infinitive usually means you did not forget to do something. Remember + gerund means you have a memory of something that happened. Forget works in the same contrast: forget to do = not do it because you did not remember; forget doing = have no memory of doing it. Stop + to-infinitive means pause one action in order to do another, while stop + gerund means quit an activity or habit. This is different from verb-plus-infinitive patterns like want to do, and verb-plus-gerund patterns like enjoy doing, where the choice is mainly grammatical and the meaning is stable. For Vietnamese learners, the main risk is translating all these as một mẫu duy nhất like nhớ/quên/dừng + V, but English separates the meanings clearly.

The trap
I remembered calling my mother.

Remember + to-infinitive means you did not forget to do the action. In Vietnamese, learners often use the same idea for both nhớ làm and nhớ đã làm, but English makes this distinction.
I remember to meet her at the conference.
I remember meeting her at the conference.
Remember + gerund means you have a memory of the past action. It does not mean you did the action now or that you must do it later.
She stopped to smoke last year.
She stopped smoking last year.
Stop + gerund means to quit an activity or habit completely. Vietnamese learners may translate it as dừng để làm gì đó, but English uses the gerund here for quitting.
He stopped answering the phone.
He stopped to answer the phone.
Stop + to-infinitive means to pause one activity in order to do another. It does not mean he quit answering the phone as a habit.

Forget + to-infinitive means you did not remember to do the action, so it was not done.
