在英语中,I am = I 'm 还有其他类型的简写吗,可以给举个例子吗?英语中一共有多少这样的写法呢.

有很多种哦.
they're =they are
she's =she is/has 要注意,这里的she is 和 she has 的缩略语是一样的哦,都是she’s
he's= he is/has 同上.因此做题时要判断一下,可能会有陷阱的.
we' re= we are
i have=i've
do not= don’t
does not=doesn't
they have=they've
have not=haven't
is not =isn't
are not=aren't
was not=wasn't
has not=hasn't
were not=weren't
等等等.有很多
