正确啊,不过用的时候需要加上宾语。比如:
Do you know how to spell this word? 你知道怎么样拼写这个单词吗?
希望能帮到你。
how to spell是不能单独成句的,只能作句子里的一个成分。
疑问词who、whom、whose、what、which、where、when、how后接动词不定式,可以构成一种特殊的不定式短语,在句中作主语,宾语,表语,但不能单独成句,如:
The little girl didn't know what to do.
Do you know where to go?
Who to bell the cat is a big problem.
Please tell me where to buy handmade shoes.
I know how to operate the machine.
希望我能帮助你解疑释惑。
成分不全。
