need的用法

Answer 1

need”作为情态动词的用法
一、need表示“需要”或“必须”,通常用于否定句,疑问句,条件句.例如：1．You
needn't
do
it
again．你不需要重复做了.2．He
needn't
worry
about
it．这件事他无需担心.3．Need
he
do
this
homework
first?他需要先做这些作业吗?4．Need
they
fill
in
the
form?他们需要填表吗?二、在否定句中,可以用need的否定形式＋不定式完成体.例如：1．We
needn't
have
worried．其实我们不必要慌.2．You
needn't
have
mentioned
it．你本来不必提起这件事.3．You
needn't
have
said
that
when
he
asked．当他问的时候,你其实不必要说.三、needn't后的不定式间或也能用进行式或被动语态.例如：1．He
needn't
be
standing
in
the
rain．他不必要站在雨中.2．We
needn't
be
waiting
in
this
place．我们不必要在这儿等.3．The
hedges
needn't
be
trimmed
thisweek．本周树蓠不必要整修.四、其一般疑问句的答语,肯定用must,否定用needn't.Need
I
go
with
her?我需要和他一起去吗?Yes,you
must.是的,你需要去.No,you
needn't.不,你不必去.
编辑本段“need”作为实义动词时,通常用法是
人＋need
＋to
do
物＋need
＋doing
物＋need
＋to
be
done
例如：The
room
needs
cleaning
=
The
room
needs
to
be
cleaned.房间需要打扫了.另外,“need”作实义动词时后还可以直接跟名词.请看下面的例子：It
is
a
question
that
needs
very
careful
consideration．这是一个需要慎重考虑的问题
很简单的方法区别情态动词与实义动词：当need为情态动词时,意思是“必要”,否定为"needn't",后面大多接动名词,表示动作；
当need为实义动词时,意思是“需要”,否定为"don't
need",后面大多跟名词.
