A Lecture: English Vowel Length and English Derivational Doublets

By Guo Rui

At 3:30 p.m. on October 19, the School of Foreign Languages held the second lecture given by native English teachers in Zonghe A207. Professor Wang Daoming from the United States held this lecture, which was entitled "English Vowel Length and English Derivational Doublets".

The lecture was divided into two sections. In the first section, Professor Wang introduced the English Vowel Length. From the lecture, students knew that English vowels might be either long or short, and regular length alternation played an important role in the pronunciation of modern English words. In order to help students to understand that, he listed plenty of words. What''s more, he pointed out the misunderstanding of students in English pronunciation.

In the second section, Professor Wang introduced the English Derivational Doublets. Since English has borrowed words from many languages, English has many doublets where the members are related by rules, thus allowing us to rapidly expand our vocabulary. Professor Wang taught students these rules to help students to recognize them and memorize vocabulary.

During the lecture, he often asked students whether they had questions and answered them patiently. Students said that this lecture made them understand the vocabulary better from the linguistics perspective, which would contribute to their study in the future.
