答案错的,选B为什么？？如果是Awe consider that 后面加从句，应该这样的we consider that it is necessary that the instrument should be adjusted each time it is used.答案A成不了从句。另外，补充一下，consider it +adj. that （+从句） 或 +to do sth 很比较常用的同位语句式还有 think it adj. that / to do 等等再补充说明一下，（不针对任何人） it = the instrument should be adjusted each time it is used 呼，不知道有没打错字
