how引导什么从句 what引导

how可以引导名词性从句(主语、宾语和表语) 例如:How he came here isn't known.(主语从句) I don't know how he did it.(宾语从句) The problem is how he can do it.(表语从句) 亲:祝你学习进步,每天都开心V_V!望采纳,thx!

how不能引导定语从句和状语从句,但是可以用来引导名词性从句,即所谓的宾语从句/主语从句/表语从句/同位语从句.

◆例如【I don't know how to call him.】我不知道怎样称呼他.【I don't know how to do it.】我不知道该怎样做.

They want to know what to do to help us.know+疑问词+不定式 等于相应的宾语从句:They want to know what they can do to help us.因为do缺宾语,所以用what 作宾语,而how是作状语的,固不可选.如果变化一下就只能选how了:They want to know how to do it to help us.

定语从句..就是用句子去作为补充解释的,定语从句自己本身就是句子,但是引导词不仅有that

引导词有 连词that,whether,if, 关系代词what,who,whose,which 和关系副词when,where,how,why等. 时态:1·主句用一般现在时,从句可用任意时. 2·主句用过去时,.

how是关系词,引导宾语从句.how excited不是表语,excited是形容词,how引导用来表程度.而that在此无意义,不能表达这层意思.

引导的是宾语从句,如果换成where,就会改变意思,语法是没有错的.He didn't know how he was going to get the money for his wife and himself to make the trip.意思是,.

what即可引导主语从句又可引导宾语和定语how引导方式状语从句

how:1.可以引定语从句,做“方式状语”:We admired him for the way(先行词) how he faced difficulties. 2.引导名词性从句,做方式状语: (How we can increase .
