用Can还是Shall? shall my classmate come?是用shall还是will? 用shall做疑问词时,答句如果用NO来回答,是用“can't还是shouldn't shall,must,will,would,can,could,委婉程度怎么样,是不是用can最委婉,那shall呢 Shall wu put of our metting?we can have it some time next week.这句话里面是用sometime还是用some time呀? 1.shall we （get）some drinks now? 2.shall I1.shall we （get）some drinks now?2.shall I （read） an interesting story neat time?3.Can we get some food and drinks?用shall 改写 We shall stay h________.（是用healthy,还是healthily) 它的回答是i am afraid you can还是must-shall i go to the airport ? -i am afraid you can还是must 选择题----Is so hot in here.----_____I open the window for you.答案分别是shall,would,can,might为什么答案用shall不能用would和can? Shall I buy sth for you?中的shall这个shall到底是助动词,还是情态动词呢?如果是情态动词,跟can有什么区别呢?shall当情态动词讲的时候 和 can 的区别是语气强弱的区别吗? can、will、would、shall、may、must等助动词具体怎么用,还有do和have, in oyr hotel payment -------be made in cash 为什么用shall不用can ...,do you?...,can ...will you?...shall it?
