我们都知道，学英语，首先要学音标单词，其次就要学语法了。语法是英语学习的脉络。在托福考试中也是一样，语法很重要。考生对此一直搞不明白，做不好题，读不懂题，写不好文章。那么，如何突破托福语法难关，取得理想的成绩呢。北京新航道为托福考生提供考前及考试指导，帮助考生分析预测考题，解析并总结考情，一起攻克托福难关。

　　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

　　not only …but also not so…as

　　either…or the same…as

　　neither…nor 比较级(more-re) …than
