Question

【題目】The tech industry expo, which attracted more than 180, 000 people, was a reminder of the tech industry is best at: being optimistic about itself.

A. thatB. how

C. whatD. which

Answer 1

【答案】C

【解析】

考查介詞的賓語從句。句意：吸引了18萬多人參加的科技產(chǎn)業(yè)博覽會(huì)提醒人們，科技產(chǎn)業(yè)最擅長(zhǎng)的是:對(duì)自己保持樂觀。此處介詞of后面是一個(gè)賓語從句，從句沒有引導(dǎo)詞，且從句謂語部分缺少主語，所以用what其雙重作用，故選C。
