Effects of Vocabulary Knowledge of Senior High Students on Their Reading Comprehension

1. Introduction

Vocabulary is the cornerstone. In recent years, theory and empirical research on the second language vocabulary has become a new trend of vocabulary study. Apart from the vocabulary (the vocabulary breadth knowledge), researchers have been trying to more deeply explore and measure vocabulary knowledge on multiple dimensions, such as the vocabulary breadth knowledge and vocabulary depth knowledge.论文网

Meanwhile, the researchers have studied the relationships between the dimensions of vocabulary knowledge and comprehensive language abilities or inpidual skills in listening, speaking, reading and writing. For learners of English as a second language, there is no doubt that vocabulary knowledge plays an important role in the English reading. The essential relationship between the vocabulary knowledge and reading comprehension ability has no conclusion because of the confines of the development of vocabulary knowledge and testing tools and other factors.
