(二)“介词＋关系代词”的特殊用法 有时“介词＋关系代词” 前会出现不定代词(all，both，none，neither，many，few，the rest 等)、数词(分数、百分数等) 及“the＋最高级/比较级”等，用来表示部分、数目等意义。 I live in the room，the windows of which (of which the windows/whose windows) face south. 我住在一个窗户朝南的房间里。 Last week，only two people came to look at the house，neither of whom wanted to buy it. 上周只有两个人来看了房子，但是没有一个想要买的。 The football team has 15 members，the oldest of whom is 25 years old. 这支足球队有15名队员，其中最大的25岁。 在 “the＋名词＋of＋关系代词” 或 “of＋关系代词＋the＋名词” 中一定不能漏掉冠词the; 在“whose＋名词”结构中一定不能加上冠词 the。 [即学活用2]　单句语法填空 ①That includes cups，bottles，and bags，most of _____ are only good for one use.(2022·北京卷) ②The workers，some _______ stayed for four years，came from different countries. ③The committee is made up of 20 members，5 _______ are women. ④The book contains 50 poems，most ________ were written in the 1930s. ⑤There are two left，one ________ is almost finished，and the other ________ is not. ⑥The settlement is home to nearly 1，000 people，many _______ left their village homes for a better life in the city. ⑦Do you like the book __________ she learned a lot? ⑧He bought a nice computer，________ the price is not so high as expected. ⑨On the second floor there are two rooms，the larger ________ is used as a meeting room. ⑩Soon children in the camp had many new friends，_________ they shared food，stories and projects. 项目二　同(近)义词和反义词 一、基本概念 同(近)义词是指在意义上相同或相近的词汇；反义词是指在意义上相反或相异的词汇。 二、语法规则 (一)同(近)义词 1．同(近)义词是意义几乎相同的一组词语，它们词性相同。如look与see；ambition与hope，dream等。同(近)义词虽然意义相同或相近，但由于语义、感情色彩、语体色彩、词的搭配和位置分布的不同，有些同(近)义词是有差异的，在不同场合要注意它们的运用。 例如：statesman和politician在字面上都是“政治家”的意思，但是，后者往往用其贬义，表示“政客”的意思。 2．从语体角度来讲，不同的同(近)义词出现在不同的语体中，带有语体色彩。 3．在写作上，很多时候同(近)义词在从句和一些并列的语句中应用比较多，起解释说明的作用。 She is a vocalist，singer working in the CCTV.(这里的singer是对前面的名词的解释。英语中常有一些这样的句子，我们可能不一定知道第一个名词的意思，但是紧跟其后的名词我们一定学过。) 4．此外，同(近)义词也经常用在一些谚语中。 A single spark can start a prairie fire. 星星之火，可以燎原。 [即学活用3]　写出下列词语的同(近)义词 ①big—_____ ②beautiful—______ ③photo—_______ ④quick—____ ⑤be good at—__________ ⑥take a walk—_____________ ⑦homeland—__________ ⑧scared—__________ ⑨smart—__________________ ⑩flee—______ ⑪drawing—________ ⑫dish—_____ ⑬tale—_____ ⑭travel—____ ⑮view—_______ ⑯error—_______ ⑰present—____ ⑱test—___________ ⑲shore—_____ ⑳a moment ago—________ (二)反义词 语义相对或者相反的词叫作反义词。和同(近)义词一样，它们词性相同。 1．换位反义词 换位反义词就是指一种对立统一的关系，一方的存在以另一方的存在为前提，双方形成一个对立的统一体。 If A sells a watch to B，B buys a watch from A. If A gives a pen to B，B receives a pen from A. 英语中有一词多义的特征，所以反义词可能有不止一个，所以在不同的场合要注意反义词的使用。 2．固定搭配中的反义词 英语中有许多由一对反义词构成的固定搭配。例如：here and there，now and then，day and night，up and down，etc. 3．反义词在谚语中的使用 通常用对偶句，它们结构相似，意思相反。 A white lie is better than a black lie. 一个善意的谎言总比一个恶意的谎言要好。 As long as the mind is enslaved，the body can never be free. 只要思想被奴役，身体就永远不能自由。 Pain past is pleasure.苦尽甘来。 East or west，home is best. 东好西好，还是家里最好。 4．词根加上前缀/后缀形成反义词 前缀有im­， in­， un­等，后缀有­less等。在英语里，如果两个词语的意思相同或相近，那么它们就被称作同义词(synonyms)，而意思相反的词语叫作反义词(antonyms)。同义词在英语文章中的显现能够证明学习者词汇量的大小，而反义词在写作中尤为重要，俗语或者谚语以及对偶句的应用往往使文章出彩，甚至起到强调警示的作用，令人印象深刻。当然，它们也有场合的差异，色彩的不同，甚至不同的人选词也会不尽相同。 [即学活用4]　写出下列词语的反义词/用反义词完成下列句子 ①beautiful—____ ②cry—_____ ③clever—______ ④different—____ ⑤difficult—____ ⑥dirty—_____ ⑦early—____ ⑧fast—____ ⑨inside—_______ ⑩tight—_____ ⑪Actions speak louder than _____． ⑫Every white has its ______,and every _____ has its sour. ⑬All things are difficult before they are ____． ⑭Misfortunes tell us what _______ is. ⑮Failure is the mother of _______． ⑯Every advantage has its ____________． ⑰He who has never hoped can never _______． ⑱Man struggles upwards；water flows _________． ⑲A friend is easier lost than _____． ⑳A good beginning makes a good ______． Ⅰ.单句语法填空 1．Many people who had seen the film were afraid to go to the forest when they remembered the scenes __ which people were eaten by the tiger. 2．I had my primary education in this school，______ which is a hill. 3．The man __ whom you spoke is a teacher. 4．The little girl is reading a book，__ which there are many cartoons. 5．I still remember the day __ which I came here. 6．He was educated at a local grammar school，after _____ he went on to Cambridge. 7．Gun control is a subject about _____ Americans have argued for a long time. 8．There are many teenagers for the summer jobs，most of ______ have just graduated from high school. 9．John invited about 40 people to his wedding，most of ______ are family members. 10．Many children，_____ parents are away working in big cities，are taken good care of in the village. Ⅱ.用提示词的反义词或同(近)义词填空 1．Joan still keeps in touch with her ______ (latter) friends. 2．I found the noise made by the children really __________ (bearable). 3．The reason for the cultural difference is _______ (simple) for me to understand. 4．Whether the project will be a great success is still _________ (certain). 5．After spending four months in foreign countries，the soldier felt every minute at home was ________ (precious). 6．It was difficult to measure the _______ (exact) influence of this strike. 7．He was absent from school because of the ______ (serious) flu. 8．The children are _____ (keen) to know what the new teacher looks like. $
