Part 4：看句子，选出高亮单词的中文释义In particular, teachers report that on-line and asynchronous interaction allows students who are reluctant to speak in face-to-face classes to have their say.A. 亲身实践的B. 实在的C. 显而易见的D. 不同时发生的

本题考查对单词“asynchronous”中文释义的掌握。解题思路是根据对该单词的记忆或者结合句子语境来判断其准确含义。
在句子 “In particular, teachers report that on - line and asynchronous interaction allows students who are reluctant to speak in face - to - face classes to have their say.” 中，“asynchronous” 用来修饰 “interaction”（互动），结合常识，在线的互动往往不是实时同时进行的。
“asynchronous” 的常见释义就是 “不同时发生的；异步的” 。选项A“亲身实践的”、选项B“实在的”、选项C“显而易见的” 均不符合该单词的意思。
