Question

【題目】5G technology ________ several operations successfully in different Chinese hospitals recently.

A.supportsB.supportedC.will supportD.has supported

Answer 1

【答案】D

【解析】

句意：最近5G技術(shù)在不同的中國醫(yī)院已成功支持多個操作。

考查時態(tài)。supports一般現(xiàn)在時、單三形式；supported一般過去時；will support一般將來時；has supported現(xiàn)在完成時；根據(jù)副詞recently判斷句子用現(xiàn)在完成時；故選D。
