Question

he is (适合的) to be a doctor

Answer 1

我知道的就这么多,不知道行不行
1)is
a
doctor
一般疑问句，及肯定否定回答：is
he
a
doctor?yes,he
is./no,he
isn't.
变化的方法：be动词最关键，通常这样的句子，不管是第几人称，陈述句把主语放到第一位，be动词放在主语后面，然后接职业等
。
否定句：he
is
not/is't(缩写形式)a
doctor.
变化的方法：be动词依然最关键,陈述句的否定形式,只要在is(be动词)
后面加not.
(随便再告诉你,不管是第几人称,只要是这样的形式,都是在be动词(is,am,are)前后变化.若是疑问句,就把be动词放在句首就行了,其他的照抄就ok了
(2)they
like
english
very
much.
一般疑问句既肯定否定回答：do
they
like
english
very
much?yes,they
do./no,they
don't.
变化的方法是：这也是个一般疑问句,在没有be动词的情况下,就要用助动词do.道理和上面的一样.
否定句：they
don't
like
english
very
much.
变化的方法是：肯定形式改否定形式时,没有be动词就用助动词do,然后还跟上面一样,在后面加not.
(还有,变一般疑问时,也只要把do
放到最前面)
(3)he
does
his
homework
at
home.
一般疑问句及肯否定回答：dose
he
do
his
homework
at
home?
yes,he
dose./no,he
dosen't.
变化方法是：助动词do用在第三人称单数时,要加es.既然还是助动词,只要把他放在最前面就行啦.而疑问句前面已经用了dose后面的就不用加es了.
否定句：he
doesn't
do
his
homework
at
home.
变化方法是：陈述句在助动词后加not啊
