一：知识储备
1．确定填并列连词
无提示词，设空前后是两个并列成分，如两个主谓完整的句子、单词、短语等；而且相并列的成分之间是并列、转折、选择或因果关系，此时需填并列连词。
2．3个技巧要熟用
技巧1 关系分析法
分析设空前后两句话的关系，确定用哪个并列连词。
①表并列或顺承关系：用and
②表转折关系：用but
③表选择关系：用or
④表因果关系：用so(因此)，for(因为)
⑤表对比关系：用while
技巧2 搭配法
①表并列关系：as well as“也”；“二者都……”；“不但……而且……”。含有比喻的成语
②表选择关系：“不是……就是……”；.“既不……也不……”；“不是……而是……”。
技巧3 句型法
①祈使句＋and/or十陈述句，如表顺承用and，表转折用or。
②when作并列连词的常用句型：
be about ；；be on the point ；had ；等。
3：确定是状语从句
设空前后两个句子之间含有一定的逻辑关系时，应用状语从句的引导词。
3．2个关键点
非常完美张丹丹(1)重点关注几组引导词用法
原因状语从句 | as，because，since，now that等 |
地点状语从句 | where，wherever等 |
目的状语从句 | so that，in order that，for fear that，in case等 |
结果状语从句 | so that，so...， |
条件状语从句 | if，unless，so/as long as，in case |
让步状语从句 | though/although，as，even if/though，while，however，，whatever，whoever，no matter how/what/which等 |
(2)利用时间先后法巧定时间状语从句引导词
①动作同时发生：when，whenever，while，as等。
②动作接连发生：as soon as，the minute，immediately，once等。
③先后发生：before，after等。
④动作的延续：since。
⑤动作的终止或开始：till/until。
二：真题精析
1．I work not because I have to，_but__ because I want to.
解析：考查连词。与前面的not一起构成but句型，该句型意为“不是……而是……”。
2．In much of Asia, especially the so－called “rice bowl” cultures of China, Japan，Korea，_and__ Vietnam, food is usually eaten with chopsticks.
解析：句意：在亚洲大部分地区，尤其在中国、日本、韩国和越南的称为“饭碗”文化中，
食物经常是用筷子吃的。China，Japan，Korea和Vietnam之间是并列关系，故用and连接。
3．But the river wasn't changed in a few days _or__ even a few months.
解析：句意：但是河流不是几天甚至几个月就改变了的。根据but及句意判断，此处要填一个表示递进含义的词，故用or。or even“甚至”太阳表面的温度。
4．It was time for her to have a new baby, _and__ it was also time for the young panda to be independent.
解析：句意：是她有一个新宝宝的时候了，也是小熊猫独立的时候了。两个完整的独立的句子应该用连词相连。上下句之间为并列关系，故用and。并列连词可以连接平行的词、短语或句子。
5．One day, the cow was eating grass _when__ it began to rain heavily.
解析：句意：一天，这头奶牛正在吃草，突然下起了大雨。be 是固定结构，意为“正在做某事……这时……”，when是并列连词。意为“这时……”。
6．It asks you to act like water; to be flexible as well _as__ strong.
解析：句意：它要求你表现得像水一样；柔韧又坚强。as well as“以及；和”，是固定短语。用来连接两个并列成分，作用相当于and。
7．Our rooms hadn't been reserved for that week, _but__ for the week after.
解析：句意：我们的房间预订的不是那一周，而是后一周。根据前面的not判断，本空填but，不是……而是……。
8．_Unless__ you can sleep well, you will lose the ability to focus, plan and stay motivated after one or two nights.
解析：考查连词。句意：除非你能睡好，否则一两个晚上之后，你会失去专注、计划的能力和保持积极性。Unless除非，如果不。
9．_Although/While/Though__ birds use their feathers for flight, some of their feathers are for other purposes.
解析：句意：尽管鸟类用它们的羽毛来飞行，可是它们的羽毛还有一些其他用处。设空处引导让步状语从句。
10．If you don't understand something, you may research, study, and talk to other people _until/till__顺丰快递 you figure it out.
解析：句意：如果你不明白某件事情，你可以去调查、研究并与其他人商讨，直到你弄明白为止。设空处引导时间状语从句，表示“直到……为止”，故用until/till。
11．Located _where__ the Belt meets the Road, Jiangsu will contribute more to the Belt and Road construction.
解析：句意：位于“一带”和“一路”的交汇处，江苏将对“一带一路”的建设贡献更多。设空处引导地点状语从句，且在从句中作地点状语，因此用where引导。
12．_When/If__ it cried，she rocked it back and forth and gave it little comforting pats.
解析：句意：当熊猫宝宝哭的时候/如果熊猫宝宝哭．猫妈妈会轻摇并轻拍它。根据语境可知用When/if引导时间状语从句，注意在句首，首字母应该大写。
13．_Before__ she could react, I gave her a big hug and told her she didn't need to keep it a secret from me.
解析：句意：母亲还未来得及做出反应，我就给了她一个拥抱。根据句意可知该句用Before引导时间状语从句，表“在……之前”。
14．Tom is so independent that he never asks his parents' opinion _unless__ he wants their support.
