1. A.
   went
2. B.
   were going
3. C.
   had gone
4. D.
   will go

Answer 1

B
分析：由the next week說(shuō)明go on的動(dòng)作在asked動(dòng)作發(fā)生時(shí)尚未發(fā)生，應(yīng)該用過(guò)去將來(lái)時(shí)。would go on是過(guò)去將來(lái)時(shí)，were going on也是過(guò)去將來(lái)時(shí)。(延伸)從現(xiàn)在來(lái)說(shuō)尚未發(fā)生的要用一般將來(lái)時(shí)，從過(guò)去某個(gè)時(shí)候來(lái)說(shuō)尚未發(fā)生的就要用過(guò)去將來(lái)時(shí)，在結(jié)構(gòu)上也有相同之處：shall/will+動(dòng)詞原形，would(will的過(guò)去式)+動(dòng)詞原形(較少用shall的過(guò)去式should+動(dòng)詞原形)；都可以用be going to+動(dòng)詞原形(用be的時(shí)態(tài)來(lái)區(qū)別)；有些表示位置變動(dòng)的動(dòng)詞還可以用進(jìn)行時(shí)表示將來(lái)(也體現(xiàn)在be的時(shí)態(tài)上)(延伸)be going to所加的動(dòng)詞如果是go或come就不用be going to go/be going to come，而是表達(dá)成be going/be coming，因此I'm coming．是“我就來(lái)了�！倍�不是“我正在來(lái)�！�
