Where 在哪里。分析句子可知，本句为让步状语从句。所以 While“尽管”符合句意。故 B 选项正确。【点睛】一、 while 用作连词时,有以下几种含义:1. 意为“当……时候”,引导时间状语从句。2. 意为“虽然,尽管”,引导让步状语从句。3. 连接两个并列句子,表示“对比”关系。二、 while 引导状语从句时,应注意以下几点:1. while 引导的时间状语从句既可放在句首,也可放在句末;而 while 引导的让步状语从句一般放在句首,不放在句末。另外,也可以从意义上加以区分。2. while 引导让步状语从句时,如果从句的主语和主句的主语相同,那么从句的主语和谓语动词 be 都可以省略。3. while 和 when 都可以引导时间状语从句,但应注意: while 引导的时间状语从句中的谓语动词必须是延续性的动词;而 when 引导的时间状语从句中的谓语动词既可以是延续性动词,也可以是非延续性动词.当时间状语从句中的谓语动词是延续性动词时, while 和 when 可以互相替换。4. while 引导的状语从句还可以表示“某个动作正在进行的同时,另一个动作也在进行之中” 。分析句子可知，本句为让步状语从句。所以 While“尽管”符合句意。故 B 选项正确。7.（江苏省苏州市八校 2019 届高三五月三模联考）One of the true tests of leadership is the ability to recognize a problem ________ it becomes an emergency.A. when B. beforeC. after D. unless【答案】B【解析】考查连词词义辨析。句意：领导能力的真正考验之一是有能力在成为紧急情况之前就识别到问题。A. when 当…… 时；B. before 在……之前；C. after 在……之后；D. unless 除非。能够在问题严重之前就意识到问题是领导能力强的标志，故选 B。【点睛】before 的用法before 在英语中是一个比较常用的虚词，它既可作介词或副词用，也可作从属连词用。在近几年的高考试题中常常出现考查其从属连词用法的题目。下面就把其作为从属连词的用法归纳如下：1. 表示“在……之前就……” 。Mary had finished her homework before her mother returned.2. 表示“过了多久后才……，动作进行到什么程度才……” 。The man almost knocked me down before he saw me.They worked day and night about three days before everything returned to normal.3. 表示“来不及；尚未……就……” 。Before I could get in a word, he had measured me.She left the company before I could have a word with her.4. 表示“刚…就…”I had hardly sat down before the bell rang.5. 表示“不知不觉就……；还没弄清就……”Time passed quickly and three months went by before Aqiao knew it.6. 表示“宁愿……，决不……，与其……，毋宁……”常与 will 或 would 连用。I would die before I would tell.
