Question

将下列句子改为一般疑问句和否定句

1.He has borrowed a pan from Tod.
2.We have studied English for about five years.
3.Alice has already done her homework..
4.They have already gone to the theatre

Answer 1

1、They
must
begin
the
woke
now.
Must
they
begin
the
work
now?(情态动词提到句首)
They
mustn't
begin
the
work
now.(情态动词的否定句在后直接加not)
2、I
need
an
English
Chinese
dictionary.
I
don't
need
an
English
Chinese
dictionary.(此处need是实义动词，所以是一般现在时态的基本句型)
Do
I
need
an
English
Chinese
dictionary？（理由同上）
3、We
have
got
a
lot
of
money.
Have
you
got
a
lot
of
money?(是现在完成时态的句型结构)
We
haven't
got
a
lot
of
money.但通常说成We
haven't
got
much
money.因为much常用于否定句。

Answer 2

1.Need
they
begin
the
work
now?/They
needn't
begin
the
work
now.
Must必须，该否定句意即“不必”，疑问句“有没有必要”，此处need用为助动词，直接在后面加动词原形，可作为常识，记住便可。
2.Do
I
need
an
English
Chinese
dictionary?/I
don't
need
an
English
Chinese
dictionary.
此处need为行为动词，采用通常的改变形式。
3.Have
we
got
a
lot
of
money?/We
haven't
got
a
lot
of
money.
have为助动词，构成现在完成时。
