She is a beauty.(美人) Please give me a coffee. 6.用于人名前,表示說話者對此人不認識,相當于“a certain”,也可指于某名人有類似性質(zhì)的人或事物。 例如:A Mr. Chen came to see you this morning. He wishes to become a Newton.,7.有些世界上獨一無二的東西,如sun, moon, sky, universe(宇宙),world(世間,地球) ,earth (地球)等,一般前面要用定冠詞,但當他們前面有修飾語時,則要用不定冠詞。 例如:We hope we can see a full moon tonight. He sat in a chair, looking at a starry 布滿星星的 sky.,8. 在作單數(shù)可數(shù)名詞定語的形容詞最高級前, 如果不表示“最”,而表“非常”,則用不定冠詞。例如: That is a best dictionary. This is a most troublesome(費事的) case. (情形,情況) 9. 序數(shù)詞前,一般有定冠詞,但當表示“又一 個”時,則要用不定冠詞。 例如:They have a second house. When I sat down, a fifth man rose (動詞,rise的過去式 “站起來”)to speak.,10. 季節(jié)、月份、日期、三餐前有修飾語時, 用不定冠詞。 例如:We had a wonderful lunch.
