对于英语教师来说,指导学生选择一部合适的词典(包括英汉词典、英英词典和英汉双解词典等)不是一件容易的事。教师只有对常用的词典了如指掌,才能为学生选择词典提供正确而有效的指导。 For English teachers, guiding students to choose a suitable dictionary (including English-Chinese dictionaries, English-English dictionaries, English-Chinese dictionaries, etc.) is not an easy task. Teachers can only provide correct and effective guidance for students to select dictionaries if they are familiar with commonly used dictionaries.
