你说的主将从现,就是主语是将来时态,从句是一般现在时的意思:
例如:
If you go to the cinema tomorrow(从句,是现在时态),I will go with you(主语,是将来时)

4否定形式:am/is/are+not;此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
5一般疑问句:把be动词放于句首;用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。

几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
十一、 一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:
A He joined the League two years ago
B He has been in the League for two years
C It is two years since he joined the League
D Two years has passed since he joined the League
十二、 一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作), at school(上学、上课)等。此短语可与进行时态转换。请看:
Peter is at work, but Mike is at play
Peter is working, but Mike is playing
十三、 现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming, Mum! 意为“我就来,妈妈!”请看:
The train is leaving soon
The train will leave soon
十六种时态
一般现在时,一般过去时,一般将来时,一般过去将来时;
现在进行时,过去进行时,将来进行时,过去将来进行时;
现在完成时,过去完成时,将来完成时,过去将来完成时;
现在完成进行时,过去完成进行时,将来完成进行时,过去将来完成进行时.
你好!
呵呵,因为主句的谓语动词是told,表示过去时态,就是说老师说话的这个动作发生在过去。
那么第一个空就需要填写一个过去将来时的动词,为什么呢?因为,老师说话的时候,我们去the Forbidden City 的这个动作还没有发生。是对将来的假设。“我们将要去”的一般时态是“will go”那么它的过去将来时就是“would go”!
第二个空:表示的是不下雨,if作为条件状语从句,应该和主句的时态保持一致!所以,用的是过去时态,did not rain!也可以是won’t rain,但是,D选项的第一个空的答案是错误的,尽管第二个空填对了,也不可以选的。所以选择答案为C
在复合句中,由when ,as soon as ,after ,before ,until ,unless等引导的时间状语从句和由if 引导的条件状语从句,都符合“主将从现”的原则,即主句是一般将来时(或用一般现在时表示一般将来时的意义),从句要用一般现在时这是历年中考的考查热点

主将从现是指在时间状语从句和条件状语从句中,如果主句是一般将来时,从句用一般现在时替代一般将来时。
常见的有以下四种情况:
一、条件状语从句的主句是一般将来时,那么从句常常用一般现在时
如:
when
i
grow
up,
i’ll
be
a
nurse
and
look
after
patients
我长大后要当一名护士,照顾病人
二、如果主句是祈使句,那么从句通常要用一般现在时
如:don’t
laugh
at
me
when
i
make
a
mistake
我犯错误的时候不要笑话我。
三、如果主句是含有情态动词的一般现在时,根据需要从句多用现在进行时
如:you
should
be
quiet
when
you
are
in
the
reading
room
在阅览室时应保持安静
四
如果if的条件状语从句遇到变换间接和直接时
,
祈使句应用not
to
如;
she
said
not
to
close
the
window
别主句与从句:简单而言主句就是问题的中心所在。一个句子的中心意思体现在主句中。所以判断主从关系要从意思入手。
或者根据引导词来看,引导词的后面是从句。定语从句主要修饰名次与代词主要关系词有;who
whom
whose
which
that
when
where
why
表语从句置于连系动词后面做表语。
时间状语从句
when,
whenever,
while,
as,
before,
after,
since,
till,
once,
as
soon
as,etc
地点状语从句
where,wherever
原因状语从句
because,
since,
as,
for,
now
that,
etc
目的状语从句
in
order
that,
so
that,
that,
etc
结果状语从句
so…that,
so
that,
such…that,
that,
etc
条件状语从句
if,
unless,
as(so)long
as,
etc
让步状语从句
though,
although,
even
if,
even
though,
however,
whatever,
as,etc
比较状语从句
as…as,
so…as,
than,
etc
方式状语从句
as,
as
if,
as
though,
etc

主祈从现 意思是主句是祈使句从句用,一般现在时。
主情从现 意思是主句含有情态动词,从句用一般现在时。
