C.主语是复数.“高级军官们就座后,幕布升起,开始表演.”

D.根据right now判定为现在进行时.“那个老头被车撞了.他被送到了医院,现在主任医师正在给他动手术.”

1 C 就座 seat 是及物动词 be seated 是它的常考短语
2 D.is being operated 现在进行时的被动语态 ： 正在被。。。

1. C

2. D

第一题: 我也不知道该怎么选，不过可以参考（请坐下）Please be seated !Sit down！来选择，因为是复数，所以用were。

第二题：注意最后一个表达时间的词语now。

1.C After the high-ranking officials_____,the curtain rose and the play began.
2.DThe old man was run down by a car.He was taken to hospital and_____on by the chief surgeon right now,
不确定对不对

1. C， officials 为复数，故排除A，根据语境判断为被动语态，排除B，因为是被动语态，所以选were seated.

2. D ，A选项与时间状语right now 不符，排除；B选项与前面谓语动词不对等，排除，C为一般现在时的被动语态，只有D是现在进行时的被动语态，表示动作正在被进行，故选D。

   希望对你有帮助！

1. C。officials复数。排除A。整句时态是过去式，排除B，be+pp.被动语态，只有C符合这个形式。

2. D。right now现在，用于现在进行时，即be+v-ing，又是被动，即is+being+done，句意：老男人被送到医院，现在主治医生在给他做手术。
