选B.A.convince： 和人联系时的用法一般都是被动，be convinced that 如：Sally is convinced that she is the prettiest girl in the class.B.anticipate： 预期/见，预料到 anticipate (doing) sth. / anticipate that 从句 如：We anticipate that she will vote for the plan.我们预料到她会投赞成票。

C.resolve： 解决：resolve disputes 解决纠纷； 决心做某事：I resolve to contribute more to the society. 决心为社会做出更大贡献D.assure： 确保，保证，使确信 因为本身就有使动意味，故不用被动 如：I can assure you that he is reliable.我向你担保他绝对可靠。

本句意思应该是：人们预言直升飞行运输会像客机一样运送上千万乘客…… Hope these will help~^_^~
