第一句是錯的.應(yīng)該把to去掉就對了.
need not do sth不需要做某事,就等于：don't need to do sth

祝你學(xué)習(xí)進(jìn)步,更上一層樓!
不明白請及時追問,滿意敬請采納,O(∩_∩)O謝謝~~還有個問題In my opinion, students should not talk in the classes. 是等于I think students should not talk in the classes. 還是I think that students should not talk in the classes.啊？句子都是對的噢， that在從句中不做任何成分,只是賓語從句的連接詞，可以省略。所以三個句子都表達(dá)同個意思。謝謝，能不能說Therefore, in myopinion, students should not talk in the classes.They do not need to take physical education classes because they have done enough exercise from the basketball game. 這句話有錯嗎have done 改為 can get
