疑问词小结：
(1)
什么都要问的what
疑问代词what的基本含义是“什么”,通常用来询问姓名,物品,
数学运算结果或什么时间做什么事情等。
What可与grade,
class,
color等名词“结盟”，一起来询问某些相对具体的信息。
e.g.
What
grade
is
she
in?
她在几年级？
What
color
is
your
bag?
你的书包是什么颜色的？
(2)
Who是疑问代词。它的意思是“谁”，用来询问“人”。在句中作主语、宾语或表语。
e.g.
Who
do
you
want
to
help?
你想帮助谁？
当who作主语时，句子要用陈述语序，谓语动词多用单数形式。
e.g.
Who
likes
playing
basketball?
谁喜欢打篮球？
疑问词小结：
(3)
Why是疑问副词，意思是“为什么”，多用来询问原因，回答时多用连词because引导的句子，
意为“因为……”。
e.g.
—Why
do
you
like
P.E.?
你为什么喜欢体育？
—Because
I
think
it
is
very
interesting?
因为我认为它很有趣。
以why开头的否定疑问句多表示建议或请求。
e.g.
Why
don’t
you
go
to
work
a
little
earlier?
你为什么不早点上班？
=
Why
not
go
to
work
a
little
earlier?

from...to...意为“从……到……”既可指时间又可指空间
e.g.
from
Monday
to
Friday
从周一到周五
from
Beijing

finish的用法
finish作不及物动词时，意为“完成；做好”
e.g.

late
every

作及物动词，后接动词时，要用动名词形式，
