作为语法考试的单琐选择题型早已淡出大学英语四级考试，但是四级考试无处不显示语法的重要性。无论阅读、写作、完型填空，还是昕力、翻译 ，到处都渗透着语法内容。本书的语法讲解部分，是按照历年高考题和大学英语四级考试出现的语法点编写的。本书亦将作者几十年教学生涯中，学生常常提出的话法问题也尽量编入其中，可有效帮助高考英语语法欠缺，成人英语三级 考试语法知识薄弱，大学英语语法思路不清且考试技巧欠佳的各类学生，在短时间迅速掌握英语语法，顺利通过各种考试。(The unilateral choice questions, as a grammar exam, have already faded out of CET4, but CET4 attaches importance to grammar everywhere. Grammar permeates in reading,writing, cloze, listening and translation.The explanation part of grammar in the book is prepared according to the grammar points in college entrance examination and CET4 over the years.The book will also incorporate the grammar questions students have raised in the author's teaching career over several decades,which can effectively help all types of students such as those who are poor in the National Matriculation English grammar, weak in adult English (level 3) grammar, and those who are unclear about the thinking and test skills of college English grammar to quickly grasp English grammar and pass various examinations smoothly.)
