little
tired.
I
want
to
sleep.
The
weather
is
a
little
cold.
2.
Don’t
read
word
by
word.
(1)
该句是一个祈使句，省略了句子的主语you，以动词原形开头，表示命令、邀请、请求等语气。有时为了表达较委婉或客气的语气，可在句子开头或末尾加please。
例如：Open
the
door,
please!
请打开门。
Come
in,
please.
请进。
祈使句的否定句，一般在句子开头加don’t即可。
例如：

forget
to
save
the
document
before
you
turn
off
the
computer.
3.
But
whether
or
not
you
can
do
this
well
depends
on
your
learning
habit.
（1）本句是whether引导的主语从句，意为“是否”，很多时候whether可以和if互换，但是在引导主语从句、表语从句、同位语从句时一般用whether不用if
例如：
Whether
it
is
true
remains
a
question.(主语从句)那是不是真的还是个问题。
The
question
is
whether
it
is
true.(表语从句)问题是是不是真的。
We
have
a
doubt
whether
it
is
true.(同位语从句)
我们怀疑那是不是真的。
if常引导宾语从句，表示“是否”之意。当把一般疑问句的直接引语转化成间接引语时，常用if或whether作引导词。
例如：
I
asked
her,
“Do
you
study
English
here?”
我问她：“你在这里学习英语吗？”
→I
asked
her
if/
whether
she
studied
English
there.
我问她是否在那里学习英语。
【拓展】if和whether的辨析：
例如：
Everything
depends
on
whether
we
have
enough
money.?
（介词后用whether）
Whether
it
is
right
or
wrong,
I
don’t
know.?
(句首表“是否”用whether)
It
doesn’t
matter
whether
he
will
come
or
not.?
（句末有or
not
用whether）
【总结
】if和whether均可表示“是否”，一般情况下二者可以互换。但在下列条件下，只能用whether而不能用if：
（1）if后不能直接接or
not。
（2）whether可作介词的宾语。
（3）whether后可接不定式。
（4)
whether可用于句首。
（5)
whether可引导主语从句、表语从句。
