高频考点词类二　连词 考向明 解题巧 对连词的考查主要涉及并列(句)和三大从句，这是高考语法填空的重点和难点，也是易错点。特殊句式也有涉及，但考频较低。 1.分析句子，找出主干，确定是并列成分还是主从复合句，抑或是特殊句式。 2．如果设空前后是并列的单词、短语或句子，则应该使用并列连词。 3．如果是主从复合句，则分析从句和主句的关系来确定是哪种从句：(1)设空处所引导的从句和空前部分有修饰关系，则判定为定语从句；(2)设空处所引导的从句在整个句子中充当主语、宾语、表语或者同位语，则判定为名词性从句；(3)设空处所引导的从句作状语，则判定为状语从句。最后，根据句意及设空处在从句中所充当的成分来确定从句引导词。 4．如果有特殊句式的标志词，则判定为特殊句式。 [典例剖析] 【技法归纳】 【即时训练】 1．(2025·高三湖北荆州二模)The research team worked overtime for three consecutive weeks，________ they wanted to ensure all data were accurately analyzed before the conference. for　[考查并列连词表因果关系。句意：研究团队连续加班三周，因为他们要确保在会议前所有数据都被准确分析。空处连接两个完整分句，后句解释前句的原因，应用表原因的并列连词for。故填for。] 2．(2025·高三湖南长沙二模)The experiment yielded unexpected results，________ the researchers decided to repeat it under more controlled conditions. so　[考查并列连词表结果关系。句意：实验产生了意外结果，因此研究人员决定在更受控的条件下重复实验。空处连接两个完整分句，后句是前句的结果，应用表结果的并列连词so。故填so。] 3．(2025·高三福建厦门二模)The scientists couldn't decide whether to publish the findings immediately ________ to conduct additional verification tests first. or　[考查并列连词表选择关系。句意：科学家们无法决定是立即发表研究结果还是先进行额外的验证测试。空处连接两个不定式短语，表示选择关系，应用表选择的并列连词or。故填or。] 4．(2025·高三河北衡水二模)The new material is not only lightweight ________ also extremely durable, making it ideal for aerospace applications. but　[考查并列连词表递进关系。句意：这种新材料不仅重量轻而且极其耐用，使其成为航空航天应用的理想选择。空处与前面的not only构成固定搭配not only...but also，表示递进关系。故填but。] 5．(2025·高三湖南怀化二模)The laboratory has state­of­the­art equipment，________ its research database is among the most comprehensive in the country. and　[考查并列连词表并列关系。句意：该实验室拥有最先进的设备，而且它的研究数据库是全国最全面的之一。空处连接两个完整分句，表示并列关系，应用表并列的连词and。故填and。] 6．(2025·高三湖北武汉二模)Some researchers prefer traditional methods，________ others advocate for adopting the latest technologies. while　[考查并列连词表对比关系。句意：一些研究者偏爱传统方法，而另一些则主张采用最新技术。空处连接两个完整分句，表示对比关系，应用表对比的连词while。故填while。] [典例剖析] 答案　1.which/that　2.who　3.which　4.that/which　5.where　6.which/that 【技法归纳】 【即时训练】 1．(2025·高三福建龙岩二模)The groundbreaking research on quantum computing，________ was published in the prestigious journal Nature last month，has attracted worldwide attention from both academic and industrial circles. which　[考查非限制性定语从句关系词。句意：这项关于量子计算的突破性研究上个月发表在著名期刊《自然》上，引起了学术界和工业界的全球关注。空处引导非限制性定语从句修饰research，从句缺少主语，指代物，应用关系代词which。故填which。] 2．(2025·高三湖北荆州二模)The laboratory ________ which these revolutionary experiments were conducted is equipped with the most advanced instruments available in the field. in　[考查“介词＋关系代词”结构。句意：进行这些革命性实验的实验室配备了该领域最先进的仪器。空处需要与conduct搭配的介词，构成“conduct experiments in the laboratory”结构，应用in which引导定语从句。故填in。] 3．(2025·高三山东潍坊二模)The exact moment ________ the chemical reaction reached its peak temperature was recorded by high­speed thermal imaging cameras. when　[考查关系副词用法。句意：化学反应达到峰值温度的确切时刻被高速热成像相机记录下来。空处引导定语从句修饰moment，从句缺少时间状语，应用关系副词when。故填when。] 4．(2025·高三河南郑州二模)The Nobel Prize­winning scientist，________ pioneering work in genetic engineering has transformed modern medicine, will deliver a keynote speech at the conference next week. whose　[考查whose引导定语从句。句意：这位诺贝尔奖得主科学家将在下周的会议上发表主旨演讲，他在基因工程领域的开创性工作改变了现代医学。空处引导定语从句修饰scientist，从句中work需要定语，表示“科学家的”，应用关系代词whose。故填whose。] 5．(2025·高三江西南昌二模)The theoretical framework ________ the young physicist proposed at the seminar has been widely adopted by researchers in related fields. that/which　[考查关系代词作宾语。句意：这位年轻物理学家在研讨会上提出的理论框架已被相关领域的研究人员广泛采用。空处引导定语从句修饰framework，从句中proposed缺少宾语，指代物，可用that或which。故填that/which。] 6．(2025·高三浙江杭州二模)Professor Johnson，________ research team made the important discovery, will be awarded the prestigious Science Medal next month. whose　[考查whose引导非限制性定语从句。句意：Johnson教授的研究团队做出了重要发现，他将于下月被授予著名的科学奖章。空处引导定语从句修饰Professor Johnson，从句中research team需要定语，表示“Johnson教授的”，应用关系代词whose。故填whose。] 7．(2025·高三湖北荆州二模)There are still many mysteries in the universe________ remain unexplained despite decades of scientific exploration. that/which　[考查关系代词作主语。句意：尽管经过数十年的科学探索，宇宙中仍有许多未解之谜。空处引导定语从句修饰mysteries，从句缺少主语，指代物，可用that或which。故填that/which。] 8．(2025·高三辽宁大连二模)The research center________ these innovative experiments are being carried out was established just two years ago with substantial government funding. where　[考查关系副词where用法。句意：进行这些创新实验的研究中心是两年前在政府大量资助下建立的。空处引导定语从句修饰center，从句缺少地点状语，应用关系副词where。故填where。 ] [典例剖析] 【技法归纳】 【即时训练】 1．(2025·高三湖北武汉二模)________ the newly developed vaccine can provide long­term immunity against the virus remains to be confirmed through further clinical trials.
