核心时态与语态
考频分析
沪教上海版高中中,一般时态与语态是核心语法模块,考频占时态与语态总量的35%左右,贯穿
试卷所有核心题型:单项选择2-3题、完形填空3-4题、语法填空2-3题、书面表达核心考察,直接
影响句子完整性与准确性。在语境理解类题目中,一般时态与语态的辨析及应用往往是解题关键。
考查内容
。基本结构与构成规则:一般现在时(主语+动词原形第三人称单数形式)、一般过去时(主语+动
词过去式)、一般将来时(will/shall+-动词原形,be going to+动词原形)、现在进行时(am/is/are+动
词现在分词)、过去进行时(was/were+动词现在分词)的构成方式:
。时间状语与语境匹配:常与各时态搭配的时间状语(如一般现在时的often,,usually;现在进行时的
now,at the moment:一般过去时的yesterday,last week;一般将来时的tomorrow,next year;过去进
行时的at8o'clock last night)的辨析,以及在具体语境中判断时态的能力:
。特殊用法与易混点:一般现在时表客观真理、习惯性动作与现在进行时表暂时动作的区别:一般过
去时表过去发生的动作与过去进行时表过去某一时刻正在进行的动作的对比:现在进行时表计划、
安排要做的事情与一般将来时的区分等。
知识点一:一般时态与进行时态的基本构成及用法

天)、recently(最近)

4.时态与语态转换技巧
。主动变被动步骤
1.找出主动句宾语(动作承受者)作被动句主语
2.判断主动句时态,确定被动语态助动词(如一般现在时用am/is/are,一般过去时用was/were)
3.动词改为过去分词
4.主动句主语前加by(可省略)
●例句:主动:They make cars in this factory.→被动:Cars are made(by them)in this factory.

enter the room.
5.时态辨析对比
。一般过去时vs现在完成时
l.一般过去时:强调过去动作结束,与现在无关(时间标志词yesterday,.last week)

考法精析
考法一:时态与被动语态转换
核心:根据主动语态句子提示,结合时态特征,转换为正确的被动语态形式
真题1(语法填空):
The workers_(build)a new bridge over the river now.(改为被动语态)
答案:is being built
解析:原句时间标志词“now”提示现在进行时,主动语态结构为“are building”;被动语态需用
“am/is/are+being+过去分词”,主语“a new bridge”为单数,故用“is being built”。
真题2(单项选择):
Many trees_on the hills last year.
A.plant B.planted C.were planted D.are planted
答案:C
解析:时间标志词“last year”提示一般过去时,主语“trees”与“plant”为被动关系,被动语态结
构为“was/were+-过去分词”,主语复数用“were”,plant的过去分词为“planted”,故选C。
考法二:被动语态与时态结合
核心:根据时间标志词或动作逻辑,判断被动动作的时态,正确使用被动语态结构
真题1(语法填空):
A new library(build)in our school last year.
高中沪教上海版
核心时态与语态
答案:was built
解析:由时间标志词“1 ast year”可知,动作发生在过去,用一般过去时被动语态:主语为单数,be
动词用was,build的过去分词为built。
真题2(单项选择):
Many trees_in the park now to make the environment better.
A.plant B.are planting C.are being planted D.will be planted
答案:C
解析:由时间标志词“now”可知,动作正在进行,且“trees'”与“plant”为被动关系,用现在进
行时被动语态,结构为“are being+过去分词”,plant的过去分词为planted。
考法三:情态动词+时态+被动语态的综合应用
核心:结合情态动词表推测/义务的用法,判断动作发生的时间及主被动关系,掌握情态动词+不
同时态被动语态的结构(情态动词+be+过去分词情态动词+have been+过去分词)
真题1(单项选择):
The meeting_because of the heavy rain.You needn't come here now.
A.must be canceled B.must have been canceled C.should cancel D.should have canceled
答案:B
解析:根据“needn't come here now”可知会议已经取消,是对过去情况的肯定推测,用“must have
done”结构;主语“meeting”是动作“cancel”的承受者,需用被动语态,故正确结构为“must have
been canceled”。
真题2(语法填空):
This task_(finish)by next Friday.You must hurry up.
答案:must be finished
解析:根据时间标志词“by next Friday”(截止到下周五)及情态动词“must”(必须),此处表示
必须在将来完成的被动动作,结构为“情态动词+be+过去分词”,finish的过去分词为finished。
解题小妙招
时态语态妙招
时态判断看标志,没有标志品语境:
主动结构记”主谓”,被动必带be和done”;
被动中be最关键,记住be就OK:
一现被动”am/is/are”,一过被动"was/were”;
进行被动要用being”,完成被动have/has/had been”;
将来被动will be',情态被动”情态+be:
过去推测'情态+have been”,最后加上一个done。
