Scientists should be kept ______ of the latest developments in their research areas.
选项
A、inform
B、informing
C、informed
D、to inform
答案
C
解析
本题考查过去分词的用法。过去分词在意义上表示被动和完成。短语inform sb.of sth.意为“告知某人某事”,本题为inform scientists of the latest...。scientists与inform之间是被动关系,所以C项为正确答案。B项表主动,故排除;D项是不定式,不用于keep的这个用法中。在keep sb./sth.doing/done结构中,当sb./sth.与动词间是主动关系时,用动词的现在分词形式,意为“使某人或某物一直做……”;当sb./sth.与动词间是被动关系时,用动词的过去分词形式,意为“使某人或某物(被)……”。【例句】:Although no worker is in the workshop,the machine is still kept working.(尽管车间没有工人,机器仍然在运转着。)
