北京新航道为托福考生提供托福考试指导和建议。在托福考试中，若说词汇是基础，那么语法就是脉络，支撑着所有的题型。对同学来说，语法是令人头疼的，从开始接触，到学已数载，可能还是没弄明白。其实，语法并不是那么难懂，只要用心去揣摩，多做练习，就会潜移默化的懂了。在这里，我们针对托福考试中的语法进行分类解析，帮助考生复习，重拾语法信心。

　　1. 并列连词 and but or同化

　　解题要点 这类题型首要分面布在written Expression (16-40题中) 当A、B、C、D四项选择中呈现零丁的and或but 或or 时，它凡是就是此题的焦点，应按照句意判定此连词是否用错。

　　全真例题要剖析

　　(1) Harvesting of grains is affected by annual changes in temperature or in the amount of moisture, but both. (90.1)

　　[谜底] D 按照句意，这里并无转折关系。是以but 应改为or。

　　(2) Porcelain is not a single clay, and a compound of kaolin. Ball clay, feldspar. And silica. (91.1)

　　[谜底] 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，到舍寄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.

　　[谜底] A 按照句中复数谓语动词are 来判定，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.

　　[谜底] D 按照提醒词then，我们可以判定dried 和ground (grind 的曩昔分词，碾碎)是挨次先后的两个动作，并非取舍选择关系。固此or应改为and。

　　not only …but also not so…as

　　either…or the same…as
