Question

—Do you need any help?

—No, thanks. We ______________ a lot of support since last year.

A.have offered B.have been offered C.were offered D.were offering

Answer

B

【解析】

句意：——你需要帮助吗？——不，谢谢。自去年以来，我们得到了许多支持。
考查现在完成时的被动语态。offer提供。have offered现在完成时；have been offered现在完成时的被动语态；were offered一般过去时的被动语态；were offering过去进行时。主语“We”与动词offer之间是动宾关系，此处用被动语态，结合题干中“since last year”可知要用现在完成时。现在完成时的被动语态结构为have/has been offered。故选B。
