　　4.3 How to use PED properly

　　The fast development and wide use of PED is definitely true. The efficiency of English learning is closely related to the use of PED. As a result, in order to increase the efficiency of English learning, learners must learn how to use PED appropriately and sensibly.

　　4.3.1 To use PED sensibly according to different language activities

　　In extensive reading, in order to read smoothly, learners may consult the meaning of new words with the aid of PED. However, it is not suitable for learners to use PED whenever they come across new words. They should first try to guess the meaning of words based on the context, morphology or common sense. To use PED too frequently will interrupt the reading process, slow down the speed and waste a lot of time, which are unfavorable for reading comprehension. In extensive reading, because of the necessity of further understanding the meaning of words, usage and collocation, learners had better use the quality paper dictionary rather than choose PED at any time. In writing and translating, learners can refer to PED for English equivalents, but they should be warned against word-for-word translation. They should know how to distinguish the fine difference between synonyms and discern the delicate shades of meaning. What is more, with the help of download function, users could make use of the rich resources on the Internet to broaden their scope of knowledge. In addition, the graded lexicon in PED could be used for exam preparation. The various exercise and vocabulary tests in PED can hopefully get students ready for CET 4 or CET 6.

　　4.3.2 To use PED, not to depend on it

　　PED can present the enquired information on the screen instantly. Users can get what they want to know about a word, a phrase or an expression in a second. As a result, they could save much time and energy. However, it is necessary to guard against excessive dependence on PED. In order to improve the efficiency of English learning, a useful dictionary is indispensable, but the point is that PED is no more than a tool. It takes time and effort to master a language. Diligence and practice is the key to the mastery of a language.

　　4.3.3 To use PED, not to abandon the paper dictionary

　　The definition and explanation of most PEDs is concise, the pragmatic meaning, grammar, examples and some other relevant information are quite sketchy. Because of the limitations of the screen size, the content of a dictionary entry could not be completely presented at one time. In comparing the different senses of polysemic words, learners would refer to the paper dictionary rather than PED [6]. When it comes to reading, translating or writing, learners should not choose PED only if discrimination of words is necessary. 

　　All in all, from realistic and progressive perspectives, English learners should use PED to its advantages. In order to give full play to PED, users must incorporate learning contents, strategies and techniques into a whole and always bear in mind that the electronic product is only an assistant. The key to success is hard work and proper use of learning strategies [7].

　　5. Conclusion

　　The unprecedented development and exploitation of PED constitute a great shock and challenge to the paper dictionary. The rapid dev本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
