【B版句型易错点精讲】whether..or..
高中·沪教上海版·必修第一册
句型结构:Whether we choose A or B,it will influence our future.
易错点1:it指代不明导致逻辑混乱
核心知识点:
Whether we choose A or B为主语从句,it为形式主语,需明确指代主语从句内容,避免因
AB为复数名词导致it指代模糊。
典型例句对比:
典型错误:Whether we choose apples or bananas,they will influence our future..(×,误用they指代主
语从句)
正确表达:Whether we choose apples or bananas,it will influence our future..(√,it明确指代“选择苹
果或香蕉”这件事)
易错点2:whether与if混淆使用
核心知识点:
引导主语从句位于句首时只能用whether,不能用if:if不能引导位于句首的主语从句。
典型例句对比:
典型错误:If we choose A or B,it will influence our future.(×,句首主语从句误用if)
正确表达:Whether we choose A or B,it will influence our future..(√)

B版句型易错点精讲
答案:B
解析:句首引导主语从句表示“是否”,只能用whether,f不能用于句首引导主语从句。
易错点3:A与B成分形式不平行
核心知识点:
whether...or..
连接的并列成分需保持词性、结构一致(名词对名词、动名词对动名词、从句
对从句等)。
典型例句对比:
典型错误:Whether we go hiking or to swim,it will influence our future.(x,go hiking是动词短语,to
swim是不定式,结构不一致)
正确表达:Whether we go hiking or go swimming,.it will influence our future.(√,均为动词短语)
或Whether to go hiking or to swim,it will influence our future.(√,均为不定式)
真题链接(沪教上海版高中必修第一册基础训川练):
Whether
(study)abroad or
(work)locally,it requires careful consideration.
答案:to study;to work
解析:whether.or.连接两个不定式短语,保持结构平行。
易错点4:时态与句意不匹配
核心知识点:
主句谓语动词will influence表示对未来的影响,主语从句中choose的时态需符合语境,通常
用一般现在时表将来(主将从现),避免时态错误。
典型例句对比:
典型错误:Whether we will choose A or B,it will influence our future.(x,主语从句中无需用wil,用
一般现在时即可)
正确表达:Whether we choose A or B,it will influence our future.(√,主语从句用一般现在时表将来)
例句对比:
Whether she comes tomorrow or not,we will hold the meeting.(主将从现,comes用一般现在时)
Whether we chose A or B last year,,it has influenced our present life.(主现完,从句用一般过去时,符
合语境)
