【仁爱英语 七年级上册】巧学妙记:名词单数变复数
巧学妙记:名词单数变复数(一) 规则变化名词单数变复数,直接加-s 占多数;s, x, z, ch, sh 来结尾,直接加上-es;词尾是f 或fe,加-s 之前先变ve;辅母+ y 在词尾,把y 变i 再加-es;词尾字母若是o,常用三个已足够,要加-es 请记好,hero, tomato, potato。

This---these(这些) that -- those(那些)【解说】1. 英语名词有单数和复数的区别,单数表示“一”,复数表示“多于一。
”名1词由单数变复数,多数是规则的变,直接加-s,例如:book → books, girl → girls。
但以-s, -z, -x, -ch, -sh 结尾的名词,变成复数时加-es, 例如:bus → buses, buzz → buzzes, box → boxes, watch → watches, brush → brushes2. -f(e) 结尾的名词单数变复数歌诀:①树叶半数自已黄,妻子拿刀去割粮,架后窜出一只狼,就像强盗逃命忙。
②妻子持刀去宰狼,小偷吓得发了慌,躲在架后保己命,半片树叶遮目光。
例如:leaf (树叶,叶子),half (一半),self (自已),wife (妻子),knife (刀子),shelf (架子),wolf (狼), thief (窃贼,强盗) 和life (生命),这些名词变成复数时,都要改-f (e) 为v,再加-es。
3. -f 结尾的名词直接加-s 变复数歌诀:海湾边、屋顶上,首领奴仆两相望;谁说他们无信仰,证据写在手帕上。
例如:gulf, roof, chief, serf, belief, proof, handkerchief,这些名词变复数直接加-s。
注:scarf(围巾;披风) 可以先改f 为ve 再加-s,也可直接加-s。

名词变复数的题
名词变复数的题一、名词变复数的规则1. 一般情况- 规则:在名词后直接加 -s。
- 例如:book - books,pen - pens,desk - desks。
- 解析:这种情况是最常见的名词复数形式变化,大多数的可数名词在变为复数时遵循这个规则。
2. 以s,x,ch,sh结尾的名词- 规则:在词尾加 -es。
- 例如:bus - buses,box - boxes,watch - watches,brush - brushes。
- 解析:因为以这些字母结尾的名词,如果直接加 -s,发音会比较困难,所以加 -es来保持发音的顺畅。
3. 以“辅音字母+y”结尾的名词- 规则:把y变为i,再加 -es。
- 例如:city - cities,baby - babies。
- 解析:这里的“辅音字母”是指除了a,e,i,o,u之外的字母。
当y前面是辅音字母时,要先把y变成i再加 -es,这样是为了符合英语的拼写和发音规则。
4. 以“元音字母+y”结尾的名词- 规则:直接加 -s。
- 例如:day - days,boy - boys。
- 解析:因为元音字母+y结尾的单词,直接加 -s在发音和拼写上都比较简单自然。
5. 以f或fe结尾的名词- 规则:有些把f或fe变为v,再加 -es;有些直接加 -s。
- 例如:knife - knives(把fe变为v再加 -es),roof - roofs(直接加-s)。
- 解析:这是一种特殊的变化规则,需要记忆一些常见的把f或fe变为v再加 -es的单词,如knife,wife,leaf等,而像roof,proof等单词是直接加 -s 的。
6. 以o结尾的名词- 规则:有些加 -es,有些加 -s。
- 例如:potato - potatoes(加 -es),photo - photos(加 -s)。
- 解析:一般来说,有生命的以o结尾的名词加 -es,如tomato,potato 等;无生命的以o结尾的名词加 -s,如photo,piano等,但也有一些例外情况需要单独记忆。
