怎样理解从句中的陈述语序 例 I really dont know __________.(选择) Awhat to do Bwhat should i do Cwhat does.Dwhat doing
B.what to do
what to do是特殊疑问词加不定式组成的短语,作句子的宾语.又如:
I don't know when to come.
I don't understand why to take part in the party.
Can you tell me how to finish the homework?
A项应改成what I should do,也就是改成陈述语气.
C项应改成what I do,道理同上.
关于陈述语气和疑问语气:
He likes English.这是一个陈述句,是陈述语气.
把它变成一般疑问句就是:Does he like English?
这个句子是陈述语气.它借了一个助动词did提到主语前面.
又如:
He is a teacher.(陈述语气)----Is he a teacher?(疑问语气,系动词is提到主语前面了.)
