按照(老师說的去做)是动詞. Students should obey their teacher. Is it always right to obey teachers? 中文句子可以有二個以上的动詞, 按照是动詞, 去做也是动詞, 說也是动詞. Students should do as teachers say. Is it always right to do as teachers say? 译成英文句子, 有的动詞省略.

Direct translation of these sentences: 学生要按照老师的话去做。 Students should do as what teachers tell them. 去做 is the verb "do", 按照老师的话 is the prepositional phrase "as what teachers tell them". As you can see, Mandarin and English have different orders for prepositional phrases and verbs. 按照老师说的话去做，就一定对吗？ Will it always be right to do as the teachers ask? Here I change a little bit in the translation for 按照老师的话去做, but they are both right. In the Mandarin sentence, 按照老师说得话去做（to do as the teachers ask） functions as a noun of the sentence, And 就一定对吗 is the verb+adjective. 对 means "right" or "correct" in English. Hope that helps.

That means you need to have your own opinion. For example: 晚辈要按照长辈的训诫做事，但按照长辈的训诫做事，就一定对吗？ Actually this means we need innovations.

学得很认真，加油Daniel!
