3B知识点分项训练一辨别句之辨别东西（单数）
第一部分：知识点归纳：
一、辨别单一的某样东西用“it， this， that”意思是“它，这个，那个”
肯定句
“是不是”问句及其回答
特殊问句
二、单数（a an the 的用法总结)
1、以原音音素开头的可数名词，前面用an ，以辅音音素开头的可数名词前面用a 。
2、the 有两个用法，一个是“世界独一无二的事物，例如'the sun the sea
the sky the earth the moon '"。另一个表示特指某样事物，而不是随便的某样事物，此时the后面既可以加可数名词，又可以加不可数名词；既可以加可数名词单数，又可以加可数名词复数。
三、可数名词的单数：
能够数的过来的名词是可数名词，缩写成 ' c.n. '
单个的一个'c.n.' 前面需要加冠词或者限定词。例如'a, an, the, my, your,
this, that, her, his' 等。
四、正确书写句子
1、首字母要大写
2、标点符号
五、需要背诵的可数名词( c.n. )有
In the classroom：pen pencil pencil-case bag book ruler eraser
rubber box blackboard bag
desk door window table
Animals：dog duck bear bird pig panda mouse monkey cat
elephant lion rabbit hen chick butterfly fly ladybird bee

特殊问句
二、可数名词变复数规则
1、直接+s
boy boys; cat cats; room rooms;
horse horses; tree trees; rose roses;
2、以sh,ch,s或x结尾，在单数的后面加上es
class classes; box boxes; glass glasses; watch watches
3、结尾是一个子音(consonant,就是除了a,e,i,o,u之外的字母)加一个y，将y换成i，再加上es
baby babies; family families; pony ponies;
city cities; country countries;
可是，如果名词结尾是一个母音(vowel，就是a,e,i,o,u)加一个y，那只要在单数词后加一个s就成了
way ways;方法，路线 toy toys; boy boys;
4、当单数名词的结尾是f或fe时，复数的写法就是将f改为v，再加es
shelf shelves;架子 leaf leaves; wolf wolves;
可是，f结尾的单数字，有许多只需加个s就成复数（特殊记忆）
roof roofs；
5、以O结尾的
A:辅音+ O：加es [z] :
hero→heroes英雄 tomato→tomatoes西红柿
注意：凡外来词则加 s．如 photos，solos，pianos，kilos（千克）
B:元音+ O：加s [z]
zoo zoos； kangaroo kangaroos 袋鼠
6、特殊变复数
ox oxen； child children；
foot feet； goose geese； tooth teeth；
louse lice； 虱子 mouse mice；
man men； woman women；
deer deer；鹿 fish fish； sheep sheep；
三、名词变复数发音规则
清辅音后加s / s /
浊辅音后加s / z /
t后加s / ts /
d后加s / dz /
原音后的s, es / z / v后的es / z /
x,s,ch,sh后的es / iz /
Are
Aren't they
these
those lemons?
bears?
giraffes？
Yes, they are.
No, they aren't.
What
are
they?
these?
those ?
