What___ you doing for vacation? I am going to Beijing. A do B did C are D were

选C 这是考察现在进行时表示将来进行的事情.
意思是：你假期做什么?我要去北京.
现在进行时除表现在外,还可以表示将来.现在进行时表将来时常用“意图”“安排”或“打算”的含义.这种现在进行时比较生动,给人一种期待感.它常表最近或较近的将来,所用动词多是转移动词.如：(1) I’m going.我要走了.(2) I'm coming.我要来了.(3) When are you starting?你什么时候动身?表将来的现在进行时除用于转移动词外,亦可用于某些非转移动词.如：(1) I’m meeting you after class.课后我找你.(2) What are you doing next Sunday?下星期你打算干什么?(3) She is buying a new bike soon.她不久将买一辆新自行车.但偶尔也表示较远的将来.如：When I grow up,I’m joining the army.我长大了要参军.表将来的现在进行时有时含有“决心”的意思,多用在否定结构中.如：(1) I’m not going.我不走了.(2) I’m not waiting any longer.我不再等了.有时也用在肯定结构中.如：I’m backing out.我要打退堂鼓了.用这种现在进行时与对方讲话时可变成命令,不过语气比较温和.如：(1) You are staying.你留下吧.(2) Don’t forget:you are taking part too.不要忘记：你也要参加.同一般现在时一样,现在进行时也可在时间、条件或原因状语从句中表示将来.如：(1) when you are passing my way,please drop in.你什么时候路过我们家,请进来坐.（用于时间状语从句） (2) If they are not doing it,what am I to do?如果他们不干,那我该怎么办?（用于条件状语从句） (3) She is going to the dentist tomorrow because she is having a tooth filled.表示将来的现在进行时也可用在间接引语中,表示说话人相信它将是事实.如：He said he is going tomorrow.他说他明天走.表将来的现在进行时有时从属于将来时态.如：(1) On election night we’ll be telling you what’s happening in various places in this country.到了选举的夜晚,我们将把全国各地的情况告诉大家.(2) when I have time,I’ll come down to the school to see how you’re both doing.我有空时,会来学校看你们俩的学习情况.典型例题 (1）He said he________me a present unless I_______ in doing the experiment.A.had not given; had not succeeded B.would not give; succeed C.will not give; succeed D.would not give; will succeed.答案B.在时间,条件或让步主语从句中一般不用将来时.本题有He said,故为过去式.主句用将来时,故选B.此处用一般过去式代替了过去将来时.(2) 表示现在已安排好的未来事项,行程等活动.The museum opens at ten tomorrow.博物馆明天10点开门.(实际上每天如此.)
