so that/in order that子句表「目的」,通常用can, could, may, might, will, would等助動詞。
Example:
Jenny studies hard so that/in order that she can get a great score.
「no matter + 疑問詞」用法相當於「疑問詞 + ever」,用來引導表示「讓步」的副詞子句,置於主要子句的前、後皆可。
Example:
No matter how tired John is, he goes to library every night.
1. 此句型連接對等結構的字詞、片語、子句。語意強調but後所接的內容。
Example:
It is not my sister, but my mother.
此句型是「與過去事實相反」的假設語氣。should + have + p.p.表「過去應該…,事實並未…」;could + have + p.p.表「本來能夠/可能…,事實並未…」;might + have + p.p. 表「本來可能…,事實並未…」。
Example:
If I hadn’t eaten the lunch, I might have been too hungry to work.
