第二部分：不規(guī)則變化
我們經(jīng)常會(huì)看到有些名詞變復(fù)數(shù)時(shí)并沒有遵循上述規(guī)則。這就是名詞的不規(guī)則變化。還有一些名詞，單復(fù)數(shù)是同一個(gè)形式的。不過，我們還是可以通過一些比較，發(fā)現(xiàn)其中的一些奧妙。以下我將為大家講講名詞的不規(guī)則變化。
一、有些名詞中保存了英語中古舊的復(fù)數(shù)形式，如：
man-men woman-women
tooth-teeth foot-feet
child-children goose-geese
mouse-mice ox-oxen
二、有些是外來詞，仍保有原來的復(fù)數(shù)形式，如：
Phenomenon-phenomena(現(xiàn)象)
Formula-formulae(公式)
Thesis-theses(論文)
Basis-bases(基礎(chǔ))
Analysis-analyses(分析)
Criterion-criteria(標(biāo)準(zhǔn))
Crisis-crises(危機(jī))
Appendix-appendices(附錄)
三、部分單詞的復(fù)數(shù)形式不變。
例：fish→fish; sheep→sheep; cattle→cattle; deer→deer; salmon→salmon, means→means
四、compound nouns，這類復(fù)數(shù)詞是以主要的名詞來表示
例：daughter-in-law→daughters-in-law 媳婦； father-in-law→fathers-in-law岳父
man-of-war→men-of-war兵艦； maid-servant→maid-servants
step-son→step-sons晚子； son-in-law→sons-in-law。
但是，也有些合成名詞，特別是由man和woman構(gòu)成的合成名詞，里面所含的成分，全都要變?yōu)閺?fù)數(shù)，如：
Man-servant－men-servants，woman doctor－women doctors等
五、有些名詞經(jīng)常是帶著-s詞尾的，但通常都作單數(shù)看待，如：
Phonetics(語音學(xué))，physics(物理學(xué))，optics(光學(xué))，politics(政治)，news(新聞)等。
六、另一些名詞則以復(fù)數(shù)詞出現(xiàn)的機(jī)會(huì)較多
例：bellows風(fēng)箱； clothes; police; shorts短褲； scissors剪刀； spectacles眼鏡； shears大剪刀，trousers長褲，wages工資，belongings所有物， surroundings環(huán)境，savings儲(chǔ)蓄，findings調(diào)查結(jié)果，arms武器，clothes衣服，stairs樓梯，等
七、另外還有一些名詞，其復(fù)數(shù)形式有時(shí)可表示特別意思，
例：goods貨物，waters水域，fishes(各種)魚，papers文件，證件，greens青菜，manners禮貌，ruins廢墟，troops軍隊(duì)，looks外貌，times時(shí)代，等
第三部分：不可數(shù)名詞的計(jì)量方法
(1)一般用“數(shù)字+of+計(jì)量單位+名詞”表示，(注意：當(dāng)數(shù)字大于一時(shí)，表示計(jì)量單位的名詞可以有復(fù)數(shù)形式)。如：
a piece of news 一則新聞 a piece of meat 一塊肉 a glass of wine一杯酒 two bowls of rice 兩碗米 a sum of money 一筆錢 five bags of flour 一袋面粉 a drop of water 一滴水 three bottles of milk 三瓶牛奶 two pieces of advice 兩條建議
(2)用much/some/ a little/ little/ a lot of/ plenty of+不可數(shù)名詞
