语法专项突破(高中北师大版选修2-U4)
考频分析
北师大版选修2-U4中,进行时(现在完成进行时、过去完成进行时等)是重要语法点,考频占时
态模块的15%左右,主要分布在核心题型:单项选择2-3题、完形填空2-3题、语法填空1-2题、
阅读理解(辅助理解上下文语境)。在语境分析类题目中,进行时的动作持续性、未完成性及情感
色彩往往是解题关键。
考查内容
·基本时态结构:现在进行时(am/is/are+doing)、过去进行时(was/were+doing)、将来进行时(will
be doing)的构成规则与标志性时间状语
·完成进行时:现在完成进行时(have/has been doing)、过去完成进行时(had been doing)的动作持
续性与未完成性表达,与现在完成时、过去完成时的语境差异
。语境应用辨析:时间状语(如now,at this moment,,this time yesterday)提示的时态匹配,情景对话
中的动作正在进行、计划安排或情感色彩(如埋怨、赞赏)表达

recently(最近)
2.主动语态:

3.与when/before等引导的时间状语从句连用一例句:Before the rain stopped,.it had been pouring

考法精析
考法一:进行时基础构成判断

U4知识点全解
核心:根据不同进行时的定义,识别正确的时态构成形式
真题1(语法填空):
They-(play)basketball on the playground when it started to rain
答案:were playing
解析:由语境”开始下雨时正在打篮球”可知,动作在过去某时刻正在进行,用过去进行时;主语
为复数,be动词用were,play的现在分词为playing。
真题2(单项选择):
She_in this school since 2018 and she still loves teaching here.
A.works B.worked C.is working D.has been working
答案:D
解析:由时间标志词”since2018”及”still loves”可知,动作从过去持续到现在且仍在进行,用现在
完成进行时,结构为has been+动词-ing形式。
考法二:进行时与一般时态的对比应用
核心:根据语境判断动作的持续性、临时性或常态性,区分进行时与一般时态的用法差异
真题1(语法填空):
She _(always lose)her keys,which makes her mother very angry.
答案:is always losing
解析:由”ways”和后半句表抱怨的语境可知,此处需用现在进行时表情感色彩(抱怨),结构
为'am/is/are+always+动词-ing”,主语为三单,be动词用is。
真题2(单项选择):
I TV when the doorbell rang last night.
A watch B watched C was watching D am watching
答案:C
解析:由"when the doorbell rang”可知,”看电视”是过去某时刻正在进行的背景动作,需用过去进
行时,结构为”was/were+动词-ing”,主语为I,be动词用was。
考法三:进行时与被动语态的综合应用
核心:结合时间标志词判断进行时的时态(现在完成进行时/过去完成进行时),并根据动作承受者
确定被动语态结构(have/has been being+过去分词had been being+过去分词)
真题1(单项选择):
The project-by our team for two weeks when the manager checked our progress yesterday.
A.has been worked on B.had been being worked on C.is being worked on D.was worked on
5

U4知识点全解
答案:B
解析:由时间标志词for two weeks”和'when the manager checked(一般过去时)”可知,动作
在”checked'前已持续进行,需用过去完成进行时:主语'the project'是动作'work on”的承受者,用
被动语态,结构为"had been being+过去分词',work的过去分词为worked。
真题2(语法填空):
This novel(translate)into three languages since 2020 and the work is still going on
答案:has been being translated
解析:由时间标志词'since2020'和'still going on”可知,动作从过去持续到现在且仍在进行,需用
现在完成进行时;主语'this novel'”是动作translate'”的承受者,用被动语态,结构为has been being
+过去分词”,translate的过去分词为translated。.
解题小妙招
进行时态看标志,since when常相伴:
过去某刻正发生,过去进行要牢记:
现在完成进行时,动作持续到现在:
by the time加过去,过去完成进行时:
always伴随抱怨意,现在进行表情感;
进行结构be doing,be动词形随时间变。
