There are many students smoking in senior high school, the reason may be that they think they look cool or appear to be more mature while having a cigarette at hand.But there are a lot of reasons not to smoke. Smoking does harm to our health.It is dangerous to our heart and lung. A lot of diseases are caused by cigarettes.Cigarettes also have terrible smell.The seconghand smoke can also be dangerous to the others who stand around you. Therefore, no smoking in public is a strict regulation in many countries. And the most important thing is that once you come into addicitive,it's hard to get rid of it. So,we must keep far from the cigarette——for everybody's health.
高中里有很多学生吸烟,原因可能是他们觉得手中有一支烟看上去很酷或者显得更成熟。但是,不吸烟的原因有很多。吸烟有害我们的健康,对我们的心脏和肺很危险。很多疾病都是由香烟引起的,而且烟的味道不好闻。二手烟对周围的.人也很危险。因此,公共场所禁止吸烟是很多国家的一项严厉规定。最重要的是,一旦你上瘾了就很难戒掉了。所以,为了每个人的健康,我们必须远离香烟。
(一)图像在教学中的最大优势——形象性
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。
总之,运用图像进行英语教学,突破了传统教学的局限,提供了丰富的声像并茂的语言内容,最接近语言实际的自然语境,能使学生在真切的语境中学习到活的语言,实现语言习得的目标。
The components that make up haze may have negative effect on people's health especially that of the children and the elderly. Also not excluded are those who have certain diseases such as asthma, allergy, and pneumonia and lung disease. Workers working in the open air have a high risk in their health.
组件构成烟雾可能对人们的健康有负面影响特别是儿童和老人。也不排除是某些疾病如哮喘、过敏、肺炎和肺部疾病。工人工作在露天有很高的.风险在他们的健康。
Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.
Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.
Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.
In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.
今天,我收看了《新课堂——同心战“役”特别节目》令我受益匪浅,刻骨铭心。让我对新型冠状病毒有了更进一步的了解和认识,以及学习并掌握了预防措施。
首先,新型冠状病毒是一个大型病毒家族。因为表面的凸起像国王头上的王冠,所以叫冠状病毒。它是目前已知的第七种可以感染人的冠状病毒。感染人群一般出现咳嗽、发烧、头疼、胸闷等症状。
其次,新型冠状病毒肺炎虽然来势汹汹,给我们的生活都蒙上了厚厚的`阴影。但是,作为学生的我们,要把这次的疫情当作是一种学习的机会,去学习前辈这种处变不惊,舍己为人的精神,我们要利用好这个机会,静下来想一想自己的`人生规划,树立正确的人生观,价值观。把我们的祖国建设得更强大,是我们每个人的使命。另外,还要学会如何做好防护措施:第一,尽量不出门,如果必须去公共场所记得佩戴口罩;第二,要经常洗手,第三,不要过度疲劳,这样会降低免疫力。
最后为逆行的勇士们祈福,平安归来!加油中国!
