四年级语文上册,第三单元口语交际《爱护眼睛,保护视力》交际指导+交际范例

小学语文 10-17 浏览量: 分享:
语文的学习绝对不是一日之功,要靠平时的积累。那么小学生怎样才能学好语文呢?三好网小编整理了四年级语文上册,第三单元 口语交际《爱护眼睛,保护视力》交际指导+交际范例,具体详情如下:


 
让我们开展一次活动。先了解本班同学的视力情况;然后分小组对班里同学的视力情况和影响视力的原因进行分析,并交流如何保护视力;最后,全班讨论怎样才能保护好视力,提出保护视力的建议。



1.测测大家的视力


2.预防近视,养成保护眼睛的良好习惯。

近视危害这么大,为什么会近视呢?

①不注重看电视或用电脑用眼卫生。

②不注重读写卫生。

③不认真做眼保健操。

④不注重饮食。

⑤长时间打游戏引起眼疲劳……


3.针对近视的形成原因,我们可以有哪些预防措施?

(1)重点强调培养学生良好的用眼习惯。

读书写字要注意:身正肩平足落地,

用心记好三个一,胸离桌子是一拳,

眼离书本是一尺,手离笔尖是一寸,

光线充足要牢记,眼睛近视远离你。

(2)坚持做到每天做眼保健操。

(3)积极锻炼身体。

(4)保证足够的睡眠。

(5)不挑食,注意饮食均衡。

(6)不长时间看电视、打游戏、玩手机…… 


交际范例

交际范例一:保护视力的建议

一、看书时坐姿要端正,光线要充足。读写要做到眼离书本一尺,胸离桌子一拳,手离笔尖一寸。

二、不要在坐车或行走的时候看书,不要躺下看书。读写1 小时要远眺10 分钟或到户外走动,调节眼部肌肉。

三、在课间十分钟坚持做眼保健操,做眼保健操注意双手干净,穴位手法准确,力度适当。

四、尽可能少上网或看其他辐射性强的东西。注意作息时间的安排,不能让眼睛长期处于疲劳状态。

五、注意用眼卫生,不随便用手揉眼睛,用洁净的手绢或纸巾擦眼。

六、不偏食,少吃辣的食品,多吃富含维生素C 和维生素A、D 的食物。

七、定期到眼科医院作检查,听从医师的指导,逐步矫正视力或防止近视度数加深。

评析:大家从用眼习惯、用眼卫生等方面讨论了如何保护视力,角度多,考虑全面。最后形成的建议具有代表性,值得我们学习和推广。


交际范例二:爱护眼睛,保护视力

通过调查,我发现我们班大约有一半的同学视力下降了。据了解,这些同学视力下降很大一部分原因是读书写字姿势不正确。如有些人喜欢躺着看书,有些人趴着写字等等,这些不良习惯都对视力有影响。

通过询问班里的同学,我了解到:有些同学平时不太注意用眼卫生、用眼时间过长。如有些人每次看书、上网或看电视的时间都太长了,这样导致眼睛得不到休息,久而久之,视力自然会下降。

我们一定要保护好自己的眼睛。我建议大家平时看书写字时,一定要保持正确的姿势;还要注意不在强光或光线暗的地方看书;也不要走路看书;每天坚持做眼保健操。

对于如何保护好视力,我有一些建议。我们平时连续阅读和写字的时间不要过长,每隔一个小时最好让眼睛休息10分钟左右;每次上网或看电视的时间最好不要超过一小时。
