英語第三人稱單數(shù)的例句

我的兄弟當(dāng)然是第三人稱單數(shù)。
要記住人名，家庭成員或者是一個(gè)名詞的單數(shù)都是第三人稱單數(shù)。
將his
brother
wants
to
get
his
book
back.(改為否定句）
需要注意do（助動(dòng)詞）后要加動(dòng)詞原形。
所以是his
brother
doesn't
want
to
get
his
book
back.

He
is
a
student.
/
He
is
not
a
student.She
is
a
doctor.
/
She
is
not
a
doctor.It
is
a
lovely
dog.
/
It
is
not
a
lovely
dog.He
has
a
book.
/
He
doesn't
have
a
book.She
has
a

/
She
doesn't
have
a
watch.It

a

bottle.
/
It
doesn't
have

bottle.He

/
He

/
She
doesn't
like

drink
milk.It

/
It

cry
loudly.總之，若第三人稱單數(shù)后跟be動(dòng)詞，那么所有的be動(dòng)詞都是is。如果是過去式，那is就變形為was。若第三人稱單數(shù)后跟動(dòng)詞，所有的動(dòng)詞末尾都加"S"或"es"。若是要變?yōu)榉穸ň?，就把?dòng)詞換為原型，在主格（he/she/it）和動(dòng)詞之間加上"does
not"(簡(jiǎn)寫為doesn't)。
