表达指令、要求、建议等意思的句子里宾语从句的谓语通常用动词原形,无论其主语是单数还是复数.这一点在美语中尤其讲究.在英式英语中或许should+动词原形和现在时都不算错.
上面的句子在美语中被认为是不正确的.即便主句谓语是过去时,从句谓语也是动词原形:
Theydemandedthatthemanagergivethemananswer.
类似的动词还有:
Theysuggestthatthemanagergivethemananswer.
Theyrequestthatthemanagergivethemananswer.
Theyorderedthatthemanagergivethemananswer.
