“两种语言能力”特指Cummins提出的把人们的语言能力区分为基本交际技能(“BICS”)和认知/学习水平(“CALP”)两种能力。在二语习得的环境下,学生由于“BICS”欠缺而导致的学习困难比较严重。在基础英语教学中加大培养学生“BICS”的力度,尊重语言习得规律,才有可能真正提高教学效率。 “Two Language Competencies” refers specifically to the ability of Cummins to differentiate people’s speech abilities into basic communicative skills (“BICS”) and cognitive / learning levels (“CALP”). In the context of second language acquisition, students have more learning difficulties due to the lack of “BICS”. In the basic English teaching to increase students “BICS ” efforts, respect for the law of language acquisition, it is possible to really improve teaching efficiency.
