单三式的变化规则是什么?

单数不用加s,复数一般要加s,但以o,s, x ,sh ,ch 结尾的,要加es.其它的以y结尾的名词复数需要把y改成i再加es.

可以

翻译：
彼特是一名优秀的小学生.约翰叔叔就住在他家旁边.约翰叔叔举目无亲而且是一个盲人.他在彼特所在小学相近的一家工厂工作,早上7：30上班,下午4：30下班.
彼特早上8：00上学,放学时间和约翰叔叔下班时间一样.平时,他早早起床送约翰去工厂,放学后他又接叔叔下班,帮他打扫屋子并帮他煮晚饭.约翰叔叔对彼特非常感激,夸道：“彼特真是一个好孩子,他就像我的亲生儿子一样.”
动词单三式及其原形：
is-be; lives-live; has-have; works-work; goes-go; comes-come; gets-get; takes-take;
thanks-thank; says-say
不过提醒一下,文中有些地方出现错误

man-men woman-women foot-feet child-children sheep-sheep
fish表示鱼的数量时是不规则变化,还是原形,表示鱼的种类时,加"s"

live living lived lives

如果已经变了,后面的就在不变了

复数：1、直接加上s.2、th、sh、ch结尾的加es.3、y结尾的去y加ies.（y前面是元音字母的直接加s）4、名词不规则加s：（1）不需变动：sheep、fish、goldfish…… （2）o变e：goose——geese （3）无规律：child——children
完整形式：isn't=is not aren't= are not don't=do not didn't=did not doesn't=does not
wasn't=was not weren't=were not can't=can not couldn't=could not
同音词：to——too see——sea konw——no （这里我也积累不多,请见谅.）

你好,同学,才看到你发来的求助题,现在为你

them 是他们的意思,显然是复数的,虽然是第三人称（我或我们是第一人称,你或你们是第二人称,他,她,它或他们是第三人称.）,但是是复数,不是单数,所以也就不是单三.而且them是they的宾格形式.



希望能帮到你,祝更上一层楼O(∩_∩)O
有不明白的请继续追问(*^__^*)

say -says-saying-said
study-studies-studying -studied

单三：pays
过去：paid
分词：paid
现在进行：paying

He likes playing basketball.他喜欢打篮球
She always eats beef for lunch.她午餐总是吃牛肉
The boy goes to school by bus.那个男孩坐公交车去学校
Mike has a headache.迈克头疼
Marry always helps me with math.玛丽总是在数学方面帮助我

动词的三单形式是指 在一般现在时的句子中主语是第三人称单数时,行为动词相应的变化形式.如 he she it,人名,地名,His father,her friend 等等做主语的时候,行为动词词尾加-s,-es.（有几个动词是有特殊变化的）
一般疑问句就是在陈述句前加does ,再把句子中原来的三单动词变回动词原形.如
He likes apples.变为 Does he like apples?
否定句就是在动词前加doesn't,再把句子中原来的三单动词变回动词原形.如
He likes apples.变为 He doesn't like apples.

discovers discovering discovered discovered
fears fearing feared feared
wakes waking woke waken

可以
但是要注意,当like的三单形式出现的时候,这个like是个实意动词,喜欢的意思
如果在句中无ing,三单,过去式,将来时态,那么这个like就是像的意思,用作介词

都一样吧，都是第三人称要加s

speak-speaks-speaking-spoke
hear-hears-hearing-heard
find-finds-finding-found
keep-keeps-keeping-kept
type-types-typing-typed
put-puts-putting-put

过去式：disliked
单三式：dislikes
现在分词：disliking(不过这个想不出用的语境啊,这不是延续性动词,不能说“我正在不喜欢...”)

1.直接加s come-comes
2.以s,x,sh,ch和o结尾的加es watch-watches do-does go -goes
3.以辅音字母+y结尾的,变y为i再加es study-studies

go goes going went
take takes taking took
swim swims swimming swam
walk walks walking walked
run runs running ran
spend spends spending spent
live lives living lived
smell smells smelling smelt
look looks looking looked
watch watches watching watched
beat beats beating beat
hit hits hiting hit
do does doing did
work works working worked
sleep sleeps sleeping slept
eat eats eating ate
jump jumps jumping jumped
seat seats seating seated
lie lies lying lay
is is being was
help helps helping helped
find finds finding found
speak speaks speaking spoke
understand understands understanding understood
offer offers offering offered
decide decides deciding decided
like likes liking liked
hate hates hating hated

只有现在式的单数才要加s,过去式不用了,各式人称都一样形式

可以.不管什么句子,主句还是从句,只要主语是第三人称单数,一般现在时,都要用第三人称单数形式.如：He likes apples.What he likes is apples.主语从句The question is what he likes.表语从句I ask him what he like...
