题型特征：一组四个单词有两种读音，即有三个单词的划线部分读音有别于其他三个技巧指导：1•理清题意，辨清类型，是考察元音还是辅音，是考一个字母还是字母组合的发音。

2•如果划线部分是元音字母，区别这个元音字母是开音节还是闭音节。

［相对开音节：一个元音字母+—个辅音字母+不发音的e］女口bike, cake, these, home, excuse［绝对开音节：辅音字母+一个元音字母结尾，且重读］女口he, she, be, go, hi,3•如果划线部分是元音字母组合，区别这个组合是重读还是弱读；如: A. first B. bird C. term D. father很明显，前面三个都是重读，发长音/?:/，而最后一个是单词末尾的弱读，发短音/?/例题： A. farmer B. term C. father D. worker 答案：B4•思考四个单词中有没有发音异于常规发音的单词，这种方法叫特殊单词比较法。

强化识记：ir, or, ur, er在重读音节中发/?:/,（字母常在单词中间）bird, girl, skirt, thirty, work, word^ nurse, purple, her;在弱读音节中发/?/，（字母常在单词末尾）女口，over, father, mother, doctor, colour,2. n 在k, c 前发/?/，如think, thank, drink, uncle, pink;ng在单词中发/ng/，在末尾多发/?/3. oo在t,d,k前发短音/u/，女口foot, look, good, book,cook ；oo在l,m,n前发长音/u:/，女口school, room, soon, zoo,4. th发/ 0 /的情况/①动词，如think,thank, throw②数词，如three, thirteen, thirty, third, fourth, fifth③不定代词，女口thin g, , somethi ng, any thi ng, everyth ing,nothing th发/?/的情况：①亲属关系，如father, mother, brother②指示代词，如this,that, these, those, the③人称代词，如they, them,their, theirs; there④介词，如with, without4. ch 读/t?/; ck 读/k/; ph 读/f/; sh 读/?/; wh 读/w/;5. 记住这些字母组合不同的发音情况！ea: heat seat leave lead breathe /i:/head bread spread /e/ great break steak /ei/ forehead /i/ ou: group soup route /u:/mouth south loud /au/souther n country young /?/ shoulder soul /?u/ au: aunt laugh /a:/ autu mn cause fault /?:/1. 如:ie: piece niece field /i:/cities ladies /i/frie nd /e/ lie tie /ai/ee fleet sleet coffee /i:/ ei: weight feint /ei/receive deceive seize ceiling veiling height reich （（德）帝国）/ai/ foreign /i/ sovereign君主）/i/oo: good book cook /u/food cool food /u:/ blood flood /?/ear: hear clear fear gear beard tear bear pear weartear / 〃？ heard /?:/ heart /a:/honourcolour /?/ journaljourney/?:/tourist /u?/ pour mourn （哀悼）/?:/ nourish 侨育，施肥）flourish （兴旺） ur:turn nurse hurt surface /?:/ surprise survive surplus 121al:half calm palm /a:/our: hour floursour /au?/ receipt /i://i?//au/wall chalk call falltalk\A /?:l//alk /?:/ ng: fin ger Ion geryoun ger /?g/sin ger /?/th:bath path breadth cloth / 9 /breathebatheclothes/ð/ch: teacher research machi ne tech nicaltion: suggestion question /??n/sion: revisio ntelevisi on /??n/ed: asked looked stopped/t/n aked /id/wanted n eeded /id/decide nice bicycle /s/ cave curious cream /k/ exercise exit text /ks/example exami nation exist exact /gz/ luggage village tech no logy huge /cP/ hug egg /g/s: fast maps grass /s/ reas on nose /z/measure pleasure occasi on /?/b: climb lamb subtle doubt tomb comb bomb 不发音 h: hourhonorhonest exhibition 不发音w: an swer sword write two wrong 不发音 k:knifekneeknockknow kneel 不发音c, g, s, x citycourageg: age giantbag pig练习题一、判断下列各词划线部分发音是否相同，相同的打“V” 的打“X”二、找出划线部分发音不同的选项(B ) 1.
