语法归纳：情态动词can的用法
Hello,
everyone!
我是can。我是一个情态动词，表示说话人的语气或情态，我没有人
称和数的变化，在句子中不能单独作谓语，只能和紧挨着我的
一起构成
复合谓语。我的基本意思是“
”。OK，现在欢迎大家走进我的世界。
一、
can的基本用法
1.
表示
（如体力和脑力方面），意为“能；会”等。例如：
Can
you
play
the
piano
你会弹钢琴吗？
2.
表示
，多用在口语中，意为“可以；能”等。疑问句中用来
提出要求，否定句中表示不允许。例如：
Can
I
help
you
我能帮助你吗？
You
can’t
play
basketball.
你不能打篮球。
（不允许）
Can
you……,
please？“请你……好吗？”表示说话人的请求；
Can
I...？“我可以……吗？”用来征求对方是否允许自己做某事。
3.
表示
。例如：
She
can’t
be
at
home
for
I
met
her
in
the
reading
room
a
few
minutes
ago.
她不可能在家，因为几分钟前我在阅览室遇见她了。
The
moon
can’t
always
be
full.
月亮不可能常圆。
二、
can的句式变化如下：
1.
在变否定句时，直接在can后加上“
”,可缩写成
或
例如：
He
can
swim.
→
He
can’t
swim.
Emma
can
see
the
pen
on
the
desk.→
Emma
cannot
see
the
pen
on
the
desk.
2.
在变一般疑问句时，把can直接移到
前（第一人称应变为第二人称）
即可。例如：
I
can
see
an
orange
on
the
table.
→
Can
you
see
an
orange
on
the
table
其回答可用Yes,
OK或Certainly等作肯定回答；否定回答用No或Sorry。例如：
—Can
you
look
after
my
books,
please
你能照看一下我的书吗？
—OK.
可以。
用Certainly回答。此时语气更为肯定。例如：
—Can
I
see
your
guitar
我能看看你的吉它吗？
—Certainly.
当然可以。
【拓展】can与may都可以表示“许可”。在征求对方意见时用may较多。例如：May
I
go
now
现在我可以走吗？在两者都可以用时，may显得客气一些。例如：May
I
take
this
seat
比Can
I
take
this
seat
稍婉转一点。在陈述句中用can较多。例如：You
can
sit
here.
你可以坐在这里。
最后让我们一起总结一下英语中的人称代词和物主代词。请完成下列表格：
