Unit 6 返回导航 * 二、语法规则 (一)“介词＋which/whom”中介词的确定 1．根据先行词与介词的搭配习惯来确定。 I still remember the day on which I joined the army. 我仍然记得我参军的那一天。(表示具体的“在哪一天”，用介词on) 2．根据定语从句中的谓语动词或形容词确定介词。该动词或形容词常与某些介词构成固定搭配。 Unit 6 返回导航 * He is the man for whom I'm waiting for a long time. 他是我等了很久的那个人。(wait for等待，为固定搭配) He is a famous singer of whom we are proud. 他是一位我们引以为豪的著名歌唱家。(be proud of以……而自豪，为固定搭配) 3．根据句子的意思确定介词。有些句子中，定语从句中谓语动词也不是固定的动词短语。这时，需要根据句子所要表达的意思选用不同的介词。 This is the book without which I can't pass the exam. 这是一本没有它我就不能通过考试的书。(根据句意判定) Unit 6 返回导航 * with whom on which with which from which to whom [即学活用2] 单句语法填空 ①I wanted to find someone I could discuss books and music. ②I'll never forget the day she said goodbye to me. ③He referred me to some books I am not very familiar. ④The tower people can have a good view is on the hill. ⑤The man I spoke on the phone last night is very good at wrestling. Unit 6 返回导航 * (二)“介词十关系代词”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。 Unit 6 返回导航 * 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。 Unit 6 返回导航 * of which of whom of whom of which [即学活用3] 单句语法填空 1 He paid the boy $10 for washing ten windows，most hadn't been cleaned for at least a year. 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.

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。 Unit 6 返回导航 * 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 bodycan 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。 Unit 6 返回导航 * East or west，home is best. 东好西好，还是家里最好。 Unit 6 返回导航 * 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。 Unit 6 返回导航 * ugly laugh stupid same easy clean late slow [即学活用2] 写出下列词语的反义词 ①beautiful— ②cry— ③clever— ④different— ⑤difficult— ⑥dirty— ⑦early— ⑧fast— Unit 6 返回导航 * outside loose ⑨inside— ⑩tight— Unit 6 返回导航 * painting plate story trip opinion mistake gift examination Ⅰ.写出下列词语的同义词 1．drawing— 2．dish— 3．tale— 4．travel— 5．view— 6．error— 7．present— 8．test— Unit 6 返回导航 * beach just now 9．shore— 10．a moment ago— Unit 6 返回导航 * words black sweet easy fortune success disadvantage despair Ⅱ.用反义词完成下列句子 1．Actions speak louder than ． 2．Every white has its , and every has its sour. 3．All things are difficult before they are ． 4．Misfortunes tell us what is. 5．Failure is the mother of ． 6．Every advantage has its ． 7．He who has never hoped can never ． Unit 6 返回导航 * downwards found ending 8．Man struggles upwards；water flows ． 9．A friend is easier lost than ． 10．A good beginning makes a good ． Unit 6 返回导航 * 谢谢观看 $$
