英语名词单数变复数的语法规则及练习题含答案
名词的复数知识点：英语中的可数名词有单数和复数之分,复数形式的变化规则如下：一、可数名词复数的规则变化。
1.一般情况下直接在名词词尾加“s”。
如: cat →cats, friend →friends。
2.以“s、x、ch、sh”结尾的可数名词,应该在词尾加“es”。
如: bus →buses, box →boxes, watch →watches, brush →brushes。
3.以“辅音字母+ y”结尾的可数名词,应该先变“y”为“i”再加“es”。
如:library →libraries, baby →babies。
4.以“o”结尾的可数名词,有生命的名词加“es”,无生命的名词加“s”。
如:tomato →tomatoes, photo →photos。
5.以“f”或“fe”结尾的可数名词,多数情况下应该变“f”或“fe”为“ves”。
如:knife →knives。
二、可数名词复数的不规则变化。
1.单复数同形。
如: sheep →sheep, deer →deer, Japanese →Japanese, Swiss →Swiss。
2.其他形式的不规则变化。
如:man →men, woman →women, child →children。
3.以 man 和 woman 修饰名词构成的合成词变复数时,两个词都要变化。
如: woman doctor →women doctors。
三、s 在名词词尾的读音规则。
1.在/p/、/t/、/k/、/f/等清辅音后读作/s/,如: cups, hats, cakes, roofs。
2.在/s/、/z/、/ ʃ /、/ tʃ /等音素后读作/ɪz/,如: glasses, faces, roses。
3.在其他情况下读作/z/,如:days, cities, knives。
4.th在词尾原本应该读作/θ/,加 s后则多数读作/ǒz/。
如: mouth→ mouths, path →paths;但是也有不变化的情况,如: month→months；ninth→ninths; youth →youths。
