The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were comprised of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.
要练说，得练听。听是说的前提，听得准确，才有条件正确模仿，才能不断地掌握高一级水平的语言。我在教学中，注意听说结合，训练幼儿听的能力，课堂上，我特别重视教师的语言，我对幼儿说话，注意声音清楚，高低起伏，抑扬有致，富有吸引力，这样能引起幼儿的注意。当我发现有的幼儿不专心听别人发言时，就随时表扬那些静听的幼儿，或是让他重复别人说过的内容，抓住教育时机，要求他们专心听，用心记。平时我还通过各种趣味活动，培养幼儿边听边记，边听边想，边听边说的能力，如听词对词，听词句说意思，听句子辩正误，听故事讲述故事，听谜语猜谜底，听智力故事，动脑筋，出主意，听儿歌上句，接儿歌下句等，这样幼儿学得生动活泼，轻松愉快，既训练了听的能力，强化了记忆，又发展了思维，为说打下了基础。 课题：Unit3 Computers
