求翻译：小学生一般都好胜心强，喜欢表现自己，还特别容易激动。但由于自控能力较差，注意力容易分散，影响了课堂教学效果。引入竞争机制，能激发学生的有意注意。课堂上搞小组纪律竞赛，学生必然为集体荣誉而增强自控能力，上课能专心听讲、用心思考，也会自觉地监督提醒其他同学遵守纪律。“俩俩对话”是课堂教学中经常采用的一种学生间的合作学习活动，这种活动可增强学生的语言运用和交际能力。对话内容可以是学过的对话、改编的对话，也可以是学生自编的对话。对话长短不限，可以两句、四句……甚至几十句，让学生量力而行。通过”俩俩对话”，学生能人人动脑、动耳、动眼、动口，不仅巩固了所学的对话，更重要的是连那些胆小、内向的、基础差的学生也得到锻炼，从而调动了班级里各层次学生学习英语的积极性。一堂课下来，整个班级对这一对话的掌握都很好了。在巩固对话时，教师充分地利用体态语，让学生对所学的单词的意思得到了很好地巩固，并且对这些词语在日常生活中的运用有了很好地理解。是什么意思？
