英语单词拼写规则中辅音字母的双写
1. 只有一个元音字母并以单一辅音字母结尾的单音节词,如果后面接以元音字母开头的后缀,则首先要双写该辅音字母,然后再加后缀: 玫瑰
hit + ing = hitting
knit + ed = knitted
run + er = runner
但是:
keep, keeping(两个元音字母)
help, helped(两个辅音字母)
love, lover(以元音字母结尾)
qu这时相当于一个辅音字母:
quit, quitting
一个词如以w、x或y 等辅音字母结尾,加后缀时不用双写该字母:
row + ed = rowed
box + ing = boxing
2. 含有两个或三个音节的词,如果以单一辅音字母结尾的,而该辅音字母前只有一个元音字母、重音又在最后一个音节时,加后缀时应双写该辅音字母。
例如:论文检测
acquit + ed = acquitted
begin + er = beginner
deter + ed = deterred
recur + ing = recurring
但是:
murmur + ed = murmured
answer + er = answerer
orbit + ing = orbiting
focus + ed写成focused或focussed均可,而bias + ed可写成biased或biassed.
3. Handicap, kidnap, worship等词末尾的辅音字母也要双写:
handicap, handicapped
worship, worshipped
kidnap, kidnapped
4. 以字母L结尾的词,如果L前面是单独一个元音字母或两个单独发音的元音字母,加后缀时则要双写字母L:
appal, appalled
duel, duelist
repel, repellent
cruel, cruelly
model, modeling
quarrel, quarrelling
dial, dialed
refuel, refueled
signal, signaled
distil, distiller重读闭音节就要双写.重读闭音节即两个辅音中间夹一个元音.如:sit---sitting begin---beginning(重读在gin这个音节上,相当与把gin该成双写的) 像travel这种重读不在的vel,可以为travelled,也可以是traveled.还有重读r...
