托福考试中，无论哪种题型都一定会涉及到连词，听力中的连词、写作、阅读中的连词都是句子中的重点，下面介绍下连词的用法及解题要点，并列连词的命题在托福考试中占有极重要的地位。并列连接词不仅自身是命题的焦点，它还涉及到一些其它的题型，如平行结构，词类、及一致等TOEEL考试要点。所以大家一定要记住这些总结。
1. 并列连词 and but or混淆
解题要点 这类题型主要分面布在written Expression (16-40题中) 当A、B、C、D四项选择中出现单独的and或but 或or 时，它通常就是此题的焦点，应根据句意判断此连词是否用错。
全真例题要分析
(1) Harvesting of grains is affected by annual changes in temperature or in the amount of moisture， but both. (90.1)
[答案] D 根据句意，这里并无转折关系。因此but 应改为or。
(2) Porcelain is not a single clay， and a compound of kaolin. Ball clay， feldspar. And silica. (91.1)
[答案] C 此句表达的是一个取舍关系，and应改为but. “not…but”是表达转折，到舍含义的固定并列连词搭配。
3. The structure or behavior of many protozoans are amazingly comples for single-celled artimals.
[答案] A 根据句中复数谓语动词are 来判断，连词or是错误，它表述的概含是两项之一，应用单数第三人称动词。固而or应改为and。
(4) Cayenne popper comes from the seedpot of the pepper plant which is dried or then ground.
[答案] D 根据提示词then，我们可以判断dried 和ground (grind 的过去分词，碾碎)是顺序先后的两个动作，并非取舍选择关系。固此or应改为and。
2. 并列连接词词组
both…and as…as
not only …but also not so…as
either…or the same…as
neither…nor 比较级(more-re) …than
so…that to…to常与so…that
whether…or 混淆搭配
解题要点;上述并列连词词组和短语必须搭配使用，不能承意更换或省略。考题中如出现上述词组的任何一部分，则注意另一部分是否正确。
