主将从现指的是一些从句里的时态呼应..在由if,unless ,when,as soon as ,not... until 引导的从句中当主句是一般将来时,祈使句,或者含有情态动词的时候从句用一般现在时
初中阶段主将从现的句型就这五个
主句三种情况一般将来时祈使句或者含有情态动词的时候从句是一般现在时
比如
I will go to the park if it ____(not rain) tomorrow.
Please tell him the news as soon as he ___(arrive )in Beijing.
He should finish the work unless he ____(go) on a trip.
在这里主句是祈使句please...所以从句必须是一般现在时arrives
因为主句中含有should 情态动词
所以从句用一般现在时goes

A. fail

()8. ---Don’t forget to ask him to write to me.
---I won’t. As soon as he____, I’ll ask him to write to you.
You can have two days off if your work____(finish) next.首先这句话的关键词是if 而且主句中包含情态动词can 所以从句用一般现在时然后看从句的主语和谓语动词finish的关系是被动关系所以从句用一般现在时的被动语态结构主语+ am/is/ are +过去分词所以答案是is finished
( )13. --- Can I go to Beijing for my holiday, Dad?--- You can when you ____ a bit older.
A. will get
B. get
C. are getting
D. got ( )14. If he ____harder, he will catch up with us soon.A. study B. studies C. will study D. studied ( )15. Frank ____ to see his grandma if he ____ free tomorrow.
( ) 16.–When will you tell him the good news?
--I will tell him about it as soon as he ____ back.
A. will get
B. get
C. are getting
D. got 答语中关键词是when 看主句中有情态动词can 所以从句的时态用一般现在时从句的主语是you 所以动词用原形
我先说一下动词时态的题的做题步骤或者做题思路
动词时态题首先找句中的时间根据时间确定时态然后再看主语和动词的关系主动关系的话用主动语态被动关系的话用被动语态然后分别按照主动语态和被动语态的结构去寻找答案
一般现在时表示一般性习惯性经常性的动作或状态
结构主动语态肯定句主语+动词+其他。
(当主语是第三人称单数的时候动词加s/es 当主语不是第三人称单数的时候动词用原型)
一般疑问句Do / Does +主语+动词原形+其他。
(当主语是第三人称单数的时候用does 当主语不是第三人称单数的时候用do)
否定句主语+ don't / doesn't +动词原形+其他
被动语态结构肯定句主语+ am /is/ are +过去分词+其他。
否定句在am,is,are,后面加not 一般疑问句把am,is,are,提前到句首即可
大家把结构看一下
结构是需要背下来的
下面我们讲一下有哪些时间的时候我们确定用一般现在时
often , usually , sometimes , always , seldom
in the morning /afternoon/ evening
on Sunday /Monday /Tuesday / Wednesday /Thursday/ Friday/Saturday at this time of year , in the middle of the day ,
every day /week / year / month/ Sunday / January 关键词every
这里只要是every。
肯定用一般现在时
还有如果是表示某人在某地生活居住学习或者说某种语言也用一般现在时
上面的是一般现在时的时间
然后根据主谓关系确定语态
然后根据结构寻找答案
The little boy_____(water) the flowers every morning.
English ____(speak) in many countries.一般现在时的被动语态的例句is spoken Our classroom ___ often ____(clean) every two days.
<is cleaned
Tea____(grow) in South China.
is grown grow的过去时grew 过去分词grown
