electronic dictionaries__________________(使查字典更方便）

One possible version:
It is commonly accepted that using electronic dictionaries has many advantages.Those who are in favor of this idea think that it is more convenient to press some keys on the machine.
However,in my view,electronic dictionaries are not good.First of all,electronic dictionaries do not contain as much information as a qualified traditional dictionary.Furthermore,some explanations in them are so simple that they can certainly cause misunderstanding.Thirdly,a lazy attitude toward language learning is always most inefficient in the long run.
In a word,a language learner should have a good dictionary on hand,and electronic dictionaries can't take the place of the traditional ones.By choosing and using a good dictionary,we will improve a great deal in English study.
