規(guī)則變化的名詞復數(shù)形式
規(guī)則1 一般情況+s e.g. shell→shells book→books
規(guī)則2 以s, x, ch, sh結尾+es e.g. fox→foxes church→churches, bus→buses, watch→watches
規(guī)則3 以o結尾+s或+es e.g. potato→potatoes, Negro→Negroes, hero→heroes, tomato→tomatoes，(口訣：黑人英雄愛吃土豆和西紅柿)，剩下一般加s, radio→radios
規(guī)則4 以f, fe結尾的，變f, fe為ves e.g. life→lives half→halves, shelf→shelves, city→cities, wife→wives
規(guī)則5 以輔音字母+y結尾， 變y為i+es e.g. sky→skies fly→flies
不規(guī)則變化的名詞復數(shù)形式
man(men) woman(women) foot(feet) goose(geese) tooth(teeth)0
child(children) sheep(sheep) deer(deer) mouse(mice) fish(fish)
拓展：語法特征
抽象性
語法是從眾多的語法單位里抽象出其中共同的組合方式、類型及如何表達語義的規(guī)則�！罢Z法從詞和句的個別和具體的東西中抽象出來，把作為詞的變化和用詞造句的基礎一般的東西拿來，并且以此構成語法規(guī)則、語法規(guī)律�！崩鐫h語里有“看看、說說、寫寫、學習學習、討論討論”這一詞的重疊現(xiàn)象，這反映出一條詞的變化規(guī)律：有些動詞可以用重疊的方法來表示動作的某一語義類型，即表示少量或短時。又如漢語里有“心情舒暢。/服裝整齊。/步調(diào)一致。/前途光明�！边@些句子，他們意思各異，但結構相同，都是名詞在前，形容詞在后，直接組合，表示被陳述和陳述的關系，加上句調(diào)就構成了主謂句。由此可見，語法指的是抽象出來的公式，舍棄了個別的、具體的內(nèi)容，一種語言里的詞多如牛毛，由這些詞組合而成的具體短語和句子更是難以計數(shù)，但是它內(nèi)部的組合規(guī)則和格式是很有限的。語法學的任務是描寫，解釋組成詞、短語和句子的規(guī)則和格式。由此可見，語法具有抽象性、概括性。
生成性
我們可以根據(jù)有限的語法規(guī)則造出無數(shù)合格的句子來，這就表現(xiàn)了語法的生成性。語法規(guī)則的生成性，集中的表現(xiàn)在兩個方面：組合關系和聚合關系。
層次性
語法從表面上看是線性排列的東西，但是語法結構卻是有層次性的。除了聯(lián)合短語外，主謂，述賓，述補，偏正等短語都能切分出兩個直接成分。直接成分還可以進一步切分出更小的直接成分，這樣復雜短語就可以由大到小分析出若干層次。例如漢語：我們進行社會調(diào)查
|__||_____________|主謂關系
|__||________|述賓關系
|___||___|偏正關系
語法的層次性與語法的遞歸性密切相關。
系統(tǒng)性
語法是一個嚴密的立體的開放的系統(tǒng)網(wǎng)絡。所謂“嚴密”，是指系統(tǒng)的內(nèi)部是相互制約的，要受到一定的規(guī)則的支配，不是可以隨心所欲的。所謂“立體”，是指語法系統(tǒng)包括了句法結構，語法意義，語言運用這三個交叉的不同平面。所謂“開放”，是指語法系統(tǒng)是發(fā)展變化的，一直在不斷地自我完善，舊的成份被逐漸淘汰，新的因素在不斷產(chǎn)生。語法系統(tǒng)內(nèi)部又由若干個子系統(tǒng)構成，例如語素系統(tǒng)，詞類系統(tǒng)，短語系統(tǒng)，句子系統(tǒng)，句群系統(tǒng)，每個子系統(tǒng)可能由若干個孫系統(tǒng)構成。詞類系統(tǒng)內(nèi)部可以分為實詞系統(tǒng)和虛詞系統(tǒng)。句子系統(tǒng)內(nèi)部可以分為單句系統(tǒng)，復句系統(tǒng)等等，從而形成一個系統(tǒng)網(wǎng)絡。
遞歸性
遞歸是說，各種語法結構的關系是有限的，但是在語言單位的組合過程中，可以反復無限地使用這些有限的規(guī)則，從而使句法結構復雜化。例如：我買書。/我買一本書。/我買一本有趣的書。/我買一本××寫的有趣的書。
如果沒有這種“遞歸性”，某種語法規(guī)則在一個句法結構里使用過一次就不能再用了。那么，我們能夠造出的句子一定是相當簡單而缺乏變化的，一定不能靈活自如的表達各種復雜的思想感情。
穩(wěn)固性
語法與基本詞匯構成語言的基礎，具有很大的穩(wěn)固性。語法也會隨著時間的推移而發(fā)展演變，但是語法的變化比詞匯，語音的變化緩慢得多，而且語法很難受到外來因素的影響而改變。語法的穩(wěn)固性與語法的抽象性密切相關。語法是一個由各種抽象規(guī)則構成的有機系統(tǒng)，許多語法手段和語法范疇歷經(jīng)千百年而很少發(fā)生變化。
民族性
每種語言都有明顯的民族特點。不僅表現(xiàn)在語音和詞匯上，也表現(xiàn)在語法上。漢語的語法比較隱蔽，漢語語法的民族性特點是在同其他語言的比較中得出的。漢語語法中語序和虛詞的運用非常重要。印歐語常用詞尾的形態(tài)變化來表示句法功能的變化。比較：
漢語是SVO型語言：陳述句一般順序是：主語+動詞+賓語。
日語是SOV型語言：陳述句的順序是：主語+賓語+動詞。
英語：由于沒有量詞，數(shù)詞可以直接和名詞組合。如：a table(桌子)/a pen(鋼筆)。漢語口語數(shù)詞一般不能直接與名詞組合，中間要用量詞來組接，并且哪個名詞與哪個量詞組合有一定的搭配習慣。如：一張桌子……，但文言文中數(shù)詞可與名詞組合(因為文言文產(chǎn)生時，漢語里還沒有量詞)，如“一桌一椅一扇一撫尺而已”，“一草一木”。世界上有許多語言，詞語的排列順序是比較自由的。如在俄語中，“我愛祖國”便有三種語序，漢語卻是另外一種情形，語序非常重要。
