  • 1. 名词复数的规则变化 一般情况 加 -s

    以y结尾的专有名词,或元音字母+y 结尾的名词变复数时,直接加s变复数.例如:

    monkey---monkeys  holiday---holidays  以辅音字母加y结尾的名词,变y为i加es: cities, babies, enemies 以o 结尾的名词,变复数时:

    a. 加s,如: photo---photos   piano---pianos

    radio---radios   zoo---zoos;

    b. 加es,如:potato--potatoes  tomato--tomatoes

    c. 上述a和b两种方法均可,如zero---zeros / zeroes 以f或fe 结尾的名词变复数时:

    a. 加s,如: belief---beliefs  roof---roofs

    safe---safes  gulf---gulfs;

    b. 去f,fe 加ves,如:half---halves

    knife---knives leaf---leaves  wolf---wolves

    wife---wives  life---lives  thief---thieves;

    c. 上述a和b两种方法均可,如handkerchief: handkerchiefs / handkerchieves名词复数的不规则变化

    1) child---children  foot---feet  tooth---teeth

    mouse---mice    man---men  woman---women

    以s、x、sh、ch结尾的名词加es: glasses, boxes, brushes, matches.单复数同形.如:     sheep---sheep deer---deer     fish---fish people---people动词后加-ing的规则1.英语动词加-ing,通常是在原形词尾直接加-ing构成:cough—coughing,climb—climbing,stand—standing,fight—fighting2.以-e结尾的动词(1)如果动词原形以一辅音加一不发音的-e结尾,一般应去掉e再加ing:write—writing,hope—hoping,care—caring,stare—staring,plane—planing,have—having,save—saving, produce—producing, breathe—breathing(2)以-ie结尾的动词应先将e去掉,将i变成y然后再加-ing:die—dying,tie—tying,vie—vying,lie—lying(3)以-ee,-oe,-ye结尾的动词加-ing时应保留词尾e:see—seeing,flee—fleeing,free—freeing,agree—agreeing,hoe—hoeing, dye—dyeing,eye—eyeing(4)以-ue结尾的动词大多应先去e再加-ing:sue—suing,imbue—imbuing,construe—construing,pursue—pursuing,rue—ruing有时,词尾e可去掉也可保留:glue—gluing或 glueing,cue—cuing或 cueing, blue—blueing或 bluing,true—truing或trueing,clue—clueing或cluing3.以一元音加一辅音结尾的动词(1)如果动词最后一音节为重读闭音节,最后一个字母需要重复:run—running, stop—stopping, hop—hopping, plan—planning,star—starring, control—controlling但辅音x是个例外,无需重复(x其实起着两个辅音的作用):tax—taxing,relax—relaxing(2)如果动词最后一个音节为次重读音节,最后一个字母有时也重复:kidnap—kidnapping或kidnaping,program—programming或programing(3)如果动词最后一个音节为非重读音节,最后一个字母大多无需重复:open—opening,offer—offering,audit—auditing但在有些动词中,重复或不重复均可:worship—worshiping或 worshipping,focus—focusing或 focussing,cancel—canceling或cancelling,travel—traveling或travelling
