(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。
绿川幸是我最喜爱的日本漫画家之一。他的漫画作品大多以短篇为主,构思巧妙,因而拥有众多漫迷。
Through her works, my favorite one is Xiamuyourenzhang.
在她的作品中我最喜爱的一部是《夏目友人帐》。
The comic book mainly talks about that the hero Xiamuguizhi has a special ability to see the bogies. He is unsociable because his parents are dead. And he often lives in his relatives' home when he is a little boy and his friends at his age always tease him because he has a special ability. Although he experiences many unfortunate things, he is still very kind and without complaint at anyone. Eventually he is adopted by a couple who is very friendly and let him go to high school. One day, He is pursued by a bogie and hid in a shrine. He breaks a powerful bogie‘s seal whose name is Ban. And that involves her grandmother Xiamulingzi’s relics--a contract that sigh with the bogies. Since then, this powerful bogie turns itself into a cat in daily life to stay with Xiamu to protect him with the condition that Xiamu should give the contract to it after he die. But before that Xiamu decides to try his best to give the name in the contracts to the bogies and let them get free. Thus, a loving, touching, scary story is opened up.
《夏目友人帐》主要讲述了男主人公夏目贵志拥有可以看到妖怪的特殊能力。因为父母双亡他的性格较为孤僻,并且由于他具有特殊的能力,他常辗转在于亲戚之间并被同龄人欺负。虽然他经历了许多不幸,但他依旧有好善良没有埋怨任何人。最终他被有好善良的藤原夫妇收养并进入高中。有一天,他被妖怪追赶躲进神社,不小心打破了一只强大妖怪斑的封印。并牵涉到了他祖母夏目玲子的遗物—一本同妖怪签订的`契约书。之后,这只强大的妖怪平时便变成猫的样子待在夏目身边保护他,但是他的条件是夏目死后要把这本契约书给它。但在此之前夏目决定尽其所能把契约书上的名字还给妖怪们让它们得到自由。由此,一个个温馨、感人、惊险的故事就此展开。
In addition, yuki midorikawa has another special work called Yinghuozhisen is also really moving ,sad and beautiful. I suggest that you all can watch it when you have free time.
此外,绿川幸的另一部作品《萤火之森》同样十分治愈感人建议大家有空可以看看。

近视眼的机理
当人眼球在调节松弛状态下,来自5米以外的平行光线经眼的屈光系统屈折后,不能聚焦在视网膜上者称非正视眼,又称屈光不正。屈光不正分为近视、远视和散光三大类。所谓近视眼是眼在调节松弛状态下,平行光线经眼的屈光系统屈折后形成的焦点在视网膜之前,在视网膜上形成一个弥散光环,所以看远处目标模糊不清。从近视眼视网膜发出的光线为集合光线,其焦点位于眼球和无限远之间,称为近视眼的远点。如被看目标恰好位于近视眼的远点上,则可在视网膜上形成焦点,所以近视眼看近距离目标清晰。
近视眼的病因
近视眼按程度分为轻度(-3.0D以下,中度(-3.0D--6.0D,高度(-6.0D以上,近视眼的病因目前尚不完全了解,可能与下列因素有关。
1.遗传因素:据调查近视有一定遗传倾向,一般认为高度近视属常染色体隐性遗传,中低度近视属多基因遗传。
2.发育因素:婴幼儿时期眼球较小,常为生理性远视,随着年龄的增长,眼轴逐渐加长而趋向正视,如发育过度则形成近视。
3.外因:青少年学生与近距离工作者中近视眼较多,这表明,近视眼的发生和发展与近距离工作有密切关系,尤其是照明不足,阅读距离过近,阅读时间过久,字体不清或过小,以及姿势不良等都与近视的发生有关。?
4、轴性近视:是指眼轴较长而眼的屈光力正常,这是最常见的一种近视。常见为发育和遗传有关,不良的卫生习惯加速发展,如阅读时灯光照明不合理,坐姿不端正,距书本及工作目标太近,以及过度用眼等。
5、屈光性近视:是指眼轴正常但眼的屈光力增强。常见有:
A.角膜膨隆,圈袍角膜。
B.晶状体异常,球悬晶体,晶体位置倾斜。
C.睫状肌痉挛,引起晶体过度调节。
When I was very small, I like to watch Mickey Mouse very much. He is so funny and makes me laugh out loudly. Later, I have seen a lot of Disney animation, and all of them attract me. The films that Disney company makes have high quality, and the plots will never let me down. Maybe no other company can please so many children.
在我很小的时候,我就很喜欢看米老鼠。它很有趣,总是可以让我大声笑出来。之后,我看过很多迪斯尼动画,都很吸引我。迪斯尼公司生产高质量的电影,故事情节永远不会让我失望。也许没有其他公司能取悦这么多的孩子。
