陈述句语序就是:主谓宾. 而疑问句的语序就是主语的位置跟谓语的换一下,而特殊疑问句其实就是在疑问句前加上了个疑问词. 例如:I came to China last year.这个是陈述句. 疑问句中的"疑问"二字就说明了句子以问号结尾.其实就是把陈述句改为一个问句. Did you come to China last year?这就是疑问句. 而特殊疑问词+疑问句构成的特殊疑问句就可以是:why did you come to China last year?
陈述型主语从句的标志:
例:That he have completed the task is amazing.
“he have completed the task”为主句主语,“is”为谓语,“amazing”为表语,而开头的“that”不属于任何成份,它存在的意义在于提示听话者that后接部分是从句,我们称这种起从句标志作用的词为从句标志词。
又如:That everyone can pass the exam is impossible.
如果将从句that进行省略,语句变成“Everyone can pass the exam is impossible.”听话者在听到前半段时会误认为说话者要表达“每个人都能通过考试”,英语为了避免这种误解,必须要用that来进行从句标志,明确的告诉听话者“每个人都能通过考试”还只是一个从句。
疑问型主语从句的从句标志:
例:What he said is not yet know. 他说了什么还不清楚。
与陈述型主语从句不同,疑问型主语从句没有从句标志词,但“what he said”是疑问半倒装句,而不是疑问完全倒装句“what did he say”,英语正是用疑问半倒装来从形式上区别疑问型主语从句与特殊疑问句。
又如: Where you went yesterday has nothing to do with me.
你昨天去哪儿与我无关。
Whether it will rain tomorrow is uncertain.明天是否下雨还不确定
