释义 🔑 aBrE /ə/NAmE /ə/BrE strong form /eɪ/NAmE strong form /eɪ/ (also an BrE /ən/ NAmE /ən/ BrE strong form /æn/ NAmE strong form /æn/) indefinite article HELP The form a is used before consonant sounds and the form an before vowel sounds. When saying abbreviations like 'FM' or 'UN', use a or an according to how the first letter is said. For example, F is a consonant, but begins with the sound /e/ and so you say: ◆an FM radio U is a vowel but begins with /j/ and so you say: ◆a UN declaration * a 用于辅音前，an 用于元音前。在 FM、UN 等缩略语前，用 a 还是用 an，需视首字母如何发音而定。如 F 是辅音字母，但其发音以 /e/ 开头，故应说：an FM radio。U 是元音字母，但其发音以 /j/ 开头，故应说：a UN declaration。🔑 used before countable or singular nouns referring to people or things that have not already been mentioned （用于可数名词或单数名词前，表示未曾提到的）一（人、事、物）◆a man/horse/unit 一个人；一匹马；一个单位◆an aunt/egg/hour/X-ray 一位姑母；一枚鸡蛋；一小时；一张 X 光片◆I can only carry two at a time. 我一次只能带两个。◆There's a visitor for you. 有位客人找你。◆She's a friend of my father's (= one of my father's friends). 她是我父亲的朋友。🔑 used before uncountable nouns when these have an adjective in front of them, or phrase following them （用于前有形容词或后有短语的不可数名词前）◆a good knowledge of French 精通法语◆a sadness that won't go away 挥之不去的悲愁🔑 any; every 任何一；每一◆A lion is a dangerous animal. 狮子是猛兽。🔑 used to show that sb/sth is a member of a group or profession （表示为某一群体或职业中的一员）◆Their new car's a BMW. 他们的新轿车是辆宝马。◆She's a Buddhist. 她是佛教徒。◆He's a teacher. 他是教师。◆Is that a Monet (= a painting by Monet)? 那是莫奈的画吗？used in front of two nouns that are seen as a single unit （用于视为一体的两个名词之前）◆a knife and fork 一副刀叉used instead of one before some numbers （用于某些数字前，代替 one）◆A thousand people were there. 那里有一千人。used when talking about prices, quantities and rates （用于价格、数量、比率等）一，每一 SYN per ◆They cost 50p a kilo. 这些东西一公斤 50 便士。◆I can type 50 words a minute. 我每分钟能打 50 个单词。◆He was driving at 50 miles an hour. 当时他正以每小时 50 英里的速度驾车。a person like sb 像（某人）的人；…式的人物◆She's a little Hitler. 她是个小希特勒。used before sb's name to show that the speaker does not know the person （用于某人姓名前，表示说话者不认识此人）有个◆There's a Mrs Green to see you. 有位格林太太要见你。used before the names of days of the week to talk about one particular day （用于一星期中某天的名称前，表示具体某一天）◆She died on a Tuesday. 她是在某个星期二去世的。
