China

already 两周前那只熊猫生了一只小熊猫，你已经忘记了？

----I
really
hate
going
to
a
place
like
that.我真讨厌去那样一个地方。
----So
do
I.我也是。
So
do
I.为倒装句，表示前面提到的肯定情况也同样适合另一个主体，意为“某某也一样”，结构为“so+be/情态动词/助动词+另一个主语”。此句所用的时态要与前句的时态相同，“be/情态动词/助动词”的形式要与后面的主语一致。如：
---Kangkang
is
a
good
student.康康是个好学生。
---So
is
Maria.玛利亚也一样。
---They
must
come.他们必须来。
---So
must

---So
does
Lily.莉莉也一样。

has
finished
the
task.汤姆完成了那项任务。
---So
have
I.我也一样。
【拓展】如果表示赞同，用“so+主语+be/情态动词/助动词”这一结构，意为“……的确如此”，主语与上文指同一人或物。如：
---It
was
cold
yesterday.昨天很冷。
---So
it
was.是的，昨天的确很冷。
---How
fast
she
runs!她跑得多快！
---So
she
does.是的，她的确跑得很快！
师生互动
S：老师，Let’s
call
him
up
now.句中him放在call
up的中间。而I’m
looking
for
him.句中him放在look
for
之后，究竟是为什么呀？
T：英语语法规定：动词搭配副词组成的词组，接代词作宾语时，代词必须放在短语中间。
S：哦，up是副词。for是介词，因而不能把him也放在中间。
T：是的。我出几道题，你来判断一下，哪些是对的，哪些是错的。
1.Your
shirt
is
durty.
Take
off
it.
2.The
problem
is
interesting.
Let’s
talk
about
it.
3.Look
at
your
basketball.
Put
it
away.
4.Don’t
worry
about
your
son.I
can
look
him
after.
S：句1中off是副词，it应放在中间；句2中about是介词，it放在后面；句3中away是副词，it放在中间；句4中after是介词，him应放在后面。
T：完全正确。你看看我给你归纳的词组：
build
up,
cheer
up,
cut
up,
eat
up,
look
up,
pick
up,
put
away,
put
on,
put
up,
take
off,
try
on,
wake
up,
work
out.
S：这些都是我们学过的“动词+副词”构成的词组。谢谢老师。
