科技的弊端和危害的英语作文【一】
Father had a family of sons who were perpetually quarrelling among themselves. When he failed to heal their disputes by his exhortations, he determined to give them a practical illustration of the evils of disunion; and for this purpose he one day told them to bring him a bundle of sticks. When they had done so, he placed the faggot into the hands of each of them in succession, and ordered them to break it in pieces. They each tried with all their strength, and were not able to do it.
He next unclosed the faggot, and took the sticks separately, one by one, and again put them into their hands, on which they broke them easily. He then
addressed them in these words: "My sons, if you are of one mind, and unite to assist each other, you will be as this faggot, uninjured by all the attempts of your enemies; but if you are divided among yourselves, you will be broken as easily as these sticks."

图像具有非凡的表现力。课堂教学中有许多内容，用文字去表述会比较抽象，而用图像去表现时却十分形象。图像具有信息量大、现场感强、直观感强、容易记忆、便于再现等特点，能充分地激活课堂的教学气氛，给教学注入新的活力。它可以多方面、多角度，以不同的形式描述某一事物，提供直观的教学素材，克服文字与口头表达形象性弱的缺点，有助于学生观察能力、自学思维能力的培养。
（二）符合初中学生的认知心理
图像输入具有直观性、新颖性、多样性和趣味性，形象生动的图像，既能提高学习效率，又能集中学生注意力，提高教学效果。图像的`运用能最大限度地调动不同感官在学习中的作用，使学生确立鲜明的、完整的表象，把注意力集中到学习的对象上，从而产生强烈的学习***和运用语言来表达的***。这种强烈的求知欲正是学生学习知识技能必须具备的内驱动力。初中学生年龄小，心理不够成熟，认知较直观，注意力不容易长时间集中，形象思维比较突出，对感性的事物较容易理解，对理性的知识则不易理解，课堂教学活动只有形式多样化，才能吸引学生注意力，激发兴趣。在教学中通过生动的语言、实物、动作、图像等创设一定的、真实的、有趣的情景，进行丰富多彩的课堂组织活动，可以激发学生的学习兴趣，充分发挥学生的主观能动性，让学生在模仿中熟悉和感知语言知识。
