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(guó)醫(yī)院已成功支持多個(gè)操作。

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