There is no such disease. 等於There isn't such a disease,沒有這樣的疾病。
not是副詞,通常位於be動詞、情態動詞、助動詞之後,構成否定形式,意思是“不”,“沒有”,它也可以位於動名詞、不定式、分詞(包括現在分詞、過去分詞)之前,構成否定形式,意思同樣是“不”,“沒有”。在省略結構裏,not可以放在包括名詞、動詞、形容詞、副詞等的壹切詞類前面,表示否定,比如:
Tim isn't a young man.
He asked me not to be late.
Let's not go.
It seems not to be right.
Not having a vocabulary book is a serious problem.
