“以为(当)”多用于与事实不符的论断。正因为如此,它们常用在反问句中。如果X是陈述性的,那么“你以为(当)X?”一定是反问句;如果X是个疑问形式,那么“你以为(当)X?”一般是直接问句,但也可能形成诘醒句③。如果X是陈述性的,“你以为(当)X呢。”是表示否定的陈述句,“你以为(当)X?”是反问句,两者虽然都表示否定,但性质是不同的。文章最后初步探讨相关句类的一些问题。 “Thought (when)” more for inconsistent with the facts of the argument. Because of this, they are often used in rhetorical questions. If X is declarative, then “do you think (when) X?” Must be a rhetorical question; if X is a questioning one, then “do you think (when) X?” Is usually a direct question but may also wake up Sentence ③. If X is declarative, “you think (when) X.” is a negative statement, “do you think (when) X?” Is a rhetorical question, although both denied, but the nature is different. At the end of the article, we discuss some problems of related sentences.
