不定式的特殊句型Why not:
"Why not +動詞原形"表達向某人提出建議,翻譯為:"為什么不……?" "干嗎不……?"
例如:
Why not take a holiday?
干嗎不去度假?
let的用法:
1)當let后只有一個單音節動詞,變被動語態時,可用不帶to 的不定式。
They let the strange go.---> The strange was let go.
2)若let 后賓補較長時,let 通常不用被動語態,而用allow或permit 代替。
The nurse let me go to see my classmate in the hospital.
----> I was allowed / permitted to see my classmate in the hospital.
用助動詞進行強調:
強調句還有一種類型,就是用助動詞do (did,does) 強調謂語。
She does like this horse. 她的確喜歡這匹馬。
Please do take care of yourself. 千萬保重。
