Our knowledge of computer.growing all the time .A、be B 、 is C 、 are D、 wereEveryone except Tom and John .there when the meeting began .A 、is B、was C、are D、were
1、B
因为knowledge是不可数名词,所以排除C、D,be动词要具体化,所以选B.
另外all the time表示一直持续,不是过去,所以也可以用来排除D.
2、B
这句可以转型为Everyone,except Tom and John,_____there when the meeting began.即expept A and B是为了补充说明的插入语,主干是 everyone____there...,everyone意味“每人”,是单数,所以在A、B中选.而meeting开始的时间是在过去,所以为B.

第一题选B 主语是knowledge 不可数
第二题选A 主语为everyone 应用单数

第一个B,因为主语knowledge 是不可数名词,c、d被排除,显然be也不对
第二个b,主语“除了。。。的everyone”是个复数主语,后面给的时态是一般过去时,因此用 was

1.B,考查主谓一致,主语knowledge是单数,所以用is
2.B,except用就远原则,everyone是单数形式,从句用过去式,所以用was
