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(rèn)識，相當(dāng)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(dú)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(dāng)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?！?，則用不定冠詞。例如： That is a best dictionary. This is a most troublesome（費(fèi)事的） case. （情形，情況) 9. 序數(shù)詞前，一般有定冠詞，但當(dāng)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.
