【句型全解】Seldom do we realize how.
高中·重大版·选择性必修第二册
基本结构
句型结构:Seldom do we realize how.
Seldom为否定副词,置于句首时句子需部分倒装,将助动词do提到主语we之前,how引
导宾语从句,作realize的宾语。
例句展示:
Seldom do we realize how much our parents have done for us.(我们很少意识到父母为我们付出了多
少)
Seldom do we realize how important it is to protect the environment.(我们很少意识到保护环境有多么
重要)
句型精讲(核心考法)
考法1:部分倒装结构的识别与应用(高中高频考点)
判断规则+例句对比
规则:句首为否定副词Seldom时,句子需使用部分倒装,即把助动词情态动词e动词提到
主语之前,结构为"Seldom+助动词情态动词be动词+主语+谓语动词原形/其他成分”,表示”很
少”
例句l:Seldom do we realize how important family is in our life.(正确,否定副词置于句首,
助动词do提前到主语we前,构成部分倒装)
例句2:Seldom we realize how precious time is.(错误,未使用部分倒装,应改为Seldom do werealize
how precious time is.

考法2:句型的陈述句转换(肯定句变倒装句)
转换规则+例句转换
规则:将肯定句中表示”很少”含义的频率副词/短语(如rarely,hardly ever等)替换为Sel-
dom,并将其置于句首,同时将原句的谓语动词部分调整为部分倒装结构(即助动词情态动词be
动词提前到主语前),原句其他成分(how引导的宾语从句)保持不变。
例句l:原句We rarely realize how valuable friendship is.
倒装句:Seldom do we realize how valuable friendship is..
例句2:原句They hardly ever realize how hard their teachers work.
倒装句:Seldom do they realize how hard their teachers work.

答案:Seldom do;realize
考法3:how引导的宾语从句引导词及语序
判断规则+例句对比
规则:句型中how”作为连接副词引导宾语从句,需置于realize之后,从句必须使用陈述语
序(即”连接词+主语+谓语+其他成分”),不可用疑问语序;ow在从句中可修饰形容词、副词
或动词,表示”多么”。
例句I:Seldom do we realize how difficult the task is.(正确,how修饰形容词difficult,从
句how difficult the task is”为陈述语序)
例句2:Seldom do we realize how is the task difficult..(错误,宾语从句使用了疑问语序,应改为how
difficult the task is)

考法4:时态一致性(主句与从句时态搭配)
判断规则+例句对比
规则:句型中主句部分倒装结构的时态需与ow引导的宾语从句时态保持一致,若主句用一
般现在时(助动词do/does),从句根据语境可用一般现在时、一般过去时等:若主句用一般过去时
(助动词did),从句通常用过去的某种时态(如一般过去时、过去完成时等)。
例句l:Seldom do we realize how much progress he has made recently..(主句一般现在时,从
句现在完成时,强调过去动作对现在的影响,时态一致)
例句2:Seldom did they realize how serious the problem was at that time.(主句一般过去时,从句一
般过去时,描述过去的情况,时态一致)
