双重所有格的用法不可数名词的复数表不同意义 双重所有格的结构和用法。 （1）结构：“of ＋ 名词所有格”和“of  ＋  名词性物主代词”。如， a novel of liuqing’s 刘青的一部小说   a room of hers 她的一个房间  （2）用法：双重所有格中带有’s所有格的名词必须是一个明确限定的指人的名词，同时of前面的名词必须是不确定的，表示很多数目中的一个或几个。它修饰的名词前常有a(an),  one, some,  many,  any, no等限定词。如， some friends of my sister’s will join us in the game.   我妹妹的一些朋友将和我们一起做游戏。 （※）注意：当of 前的名词是picture, photo, portrait, statue等时，用of 所有格和双重所有格意义不同。 一般of 所有格表示前后名词的同位关系。如，a photo of mary （指玛丽本人的照片）。而双重所有格表示拥有、所属关系。如， a photo of mary’s  （玛丽收藏的照片，不一定是她本人的照片）。 例题：1. _______ is very big.   A. The hat of Mary        B. Mary’s hat              C. The hat of Mary’s      2. Teddy is ________.   A. a student of my sister     B. a student of my sister’s     C. my sister’s students      答案：1. B  【解析】：双重所有格中常不用the，据此排除C。of常用于无生命的名词的所有格；表示有生命的单数名词的所有格常在后加’s，Mary是有生命的，其所有格是Mary’s。故选B。 2. B  【解析】： A选项意在表达“我的妹妹的学生”，但是表示人的所有格，常不用of，据此排除A。C选项中students应为单数，因为句中仅提到Teddy一人，据此排除C。B选项表示双重所有格，符合双重所有格结构“限定词 + 名词 + of + 表人的所有格”，故选B。 高中新课标英语单词 人教初中英语 高中英语课文原文 某些不可数名词的复数形式表不同意义。 常考的有： woods 树林 waters 水域 papers 文件，报纸 looks 外貌 greens 青菜 times 时代 drinks 饮料 customs 海关 works 著作 manners 礼貌 sands 沙滩 forces 军队 imports 进口货物 ashes  灰烬 spirits 心情，情绪 losses 损失物 feelings 感情 pains 辛苦 returns 长寿        例句： 1） Police believe the gunmen ran off into the woods. 警方认为持枪的歹徒逃到树林里去了。 2） Johnny has changed his image to fit the times. 约翰尼已经改变了他的形象以迎合时代潮流。 Still seeking a destination for your weekend break? There are some places which are probably a mere wall away from your college. King’s Art Centre A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists. You could attend a class teaching you how to ‘learn from the masters’ or get more creative with paint–free of charge. The Centre also runs two life drawing classes for which there is a small fee. The Botanic Garden The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University. The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss. Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals. The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid’ is regularly seen lying in the heat of the warm sun. Byron’s Pool Many stories surround Lord Byron’s time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of “mess and drunkenness”. However, it seems as though Byron did manage to pass the time pleasantly enough. I’m not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village. It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron’s Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don’t trust me, then perhaps you’ll take it from Virginia Woolf, a famous writer,—over a century after Byron, she reportedly took a trip to swim in the same pool. 1．The main idea of the passage is ________.
