宾语从句的语序要用陈述句语序,但要注意当疑问词为主语时,句式为:疑问词+谓语+其他,问句和陈述句语序一样。
典型例题:I didn't know ?
A. What wrong was with her B.what was wrong with her
C .what wrong is with her D.what is wrong with her
解析:主句是一般过去时,从句要用相应过去时态,所以排除C和D;在what was wrong with her中,what作主语,所以问句本身又是陈述句语序,不用变化。
答案:B
改写和省略是非常容易混淆的一对概念,刚讲完大数之后,小学生课后错误较高。其实“改写”与“省略”是两个不同的概念,把776400改写成用“万作单位的数”和把这个数“省略万后面尾数”得到的结果是不一样的。
1.从句为陈述句,常选择引导词that,that引导宾语从句无意义,不充当句子成分常省略。例句:He told us (that they would help us through the whole work.
2.从句为一般疑问句,常选择引导词if或whether,表示“是否”。在whether … or not结构中不能用if替换。例句:I don’t know if there will be a bus any more.
3.从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代词、副词作引导词。例句:He didn’t tell me when we should meet again.
