1.— Must we do exercise to prevent the flu? 预防流感我们必须做运动吗?
— Yes, we must. / No, we don’t have to. / No, we needn’t. 是的,必须。/不,不必。
Must we / I …? 的肯定回答:Yes, we /you must. 否定回答:No, we /you needn’t/don’t have to. 而不能用mustn’t。
have to 意思是“不得不,必须”,后跟动词原形。
He doesn’t have to walk so fast. 他不必走那么快。
2.Oh, can I leave a message? 喔,我能留个口信吗?
leave a message 留言,留口信
类似的词组:take a message 捎口信give sb. a message 给某人带个口信;
3.It’s necessary for you to learn about first aid. 你有必要学习急救。
it 是形式主语,动词不定式短语to save the patients 是真正的主语。如:
It is important for us to learn English. 对我们来说,学习英语是很重要的。
4.tell sb (not) to do sth告诉某人(不要)做某事(ask,force,advise,want,would like,wish用法相似)
