网考网解析：
[考点] 语义衔接题 [解析] 本题目选择副词，在句子中充当状语。句子叙述到He helped popularize the idea that some diseases not ______ thought to have a bacterial cause were actually infections, which aroused much controversy when it was first suggested. “他普及了这种观点，即某些以前人们认为不是由细菌引起的疾病实际上是传染病，这一观点一经提出就引起了极大的争议。”分析本句结构可以看出：that引导的是同位语从句，说明idea的内容，从句中some diseases not ______ thought to have a bacterial cause是主语部分，谓语是were actually infections，而后面which引导的非限制定语从句是修饰the idea这个名词的。解本题的关键词是actually“实际上”，隐含转折之意，即过去的看法和实际情况不同。选项A．subsequently随后；B．presently当前；C．previously先前；D．1ately近来，最近。为了与本句子中的“actually，实际上”相互呼应，要体现时间上的先后交替关系。因此，正确答案为C。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
