Question

英语改病句

Answer 1

How
much
is
the
socks?
socks是复数，谓语动词应用are
How
much
are
that
pants?
pants是复数象glasses一样只有复数，that应为those
These
shoes
are
twenty-three
dollar.
dollar是可数名词，要加s。23
dollars
That
hat
is
eight
yuans.
yuan单复数同形，要去掉s。
Forteen
and
twenty-six
is
forty.
这个是正确的啊
Have
a
look
for
the
picture.
have
a
look
at属固定搭配
They
each
has
a
bag
for
sports.
这里的主语是they，谓语应该用
复数，
has改为have。如果这个句子的语序倒一下，变成Each
of
them
则谓语用单数
We
have
many
bags.Do
you
like
it
cheap?
第二句的代词不对，代词替代的是上文中出现的词，这里是替换bags当然应该用them.
Thank
a
lot.You're
welcome.
Thanks
a
lot
是成句。作名词时，thanks本身就是以复数出现的。
I'll
take
these
short.
short改为shorts
short作名词使用时，是短裤的意思。象pants，glasses一样，通常用复数。

Answer 2

这位小友，
你这几个句子，错误的地方不仅仅是几个介词的用法。正确改法如下：
1
on
friday
星期几用on
前面的arrive
的形式也有问题。要么用过去式arrived，要么用will
arrive
用原型显然是不合适的
2
knocked
in
改为knocked
at
敲门用
konck
at
3
to
改为from
从哪回来用come
back
from
另外前面代词顺序有问题
my
teacher
and
i
把i
放后面
4
can
you改为can
they
no
one
全称否定，后面要用全称的they
