老师上课风趣幽默。当我们很无聊时,他会说一些有趣的事情,让我们放松一下。这时候,大家都打起了精神,仔细听老师讲话。不过一会儿,你就会发现,老师早已经渐渐把话题引到了课程上,可是大家仍旧睁大眼睛,一动不动地听讲呢!

教师范读的是阅读教学中不可缺少的部分,我常采用范读,让幼儿学习、模仿。如领读,我读一句,让幼儿读一句,边读边记;第二通读,我大声读,我大声读,幼儿小声读,边学边仿;第三赏读,我借用录好配朗读磁带,一边放录音,一边幼儿反复倾听,在反复倾听中体验、品味。我的老师,长的高高瘦瘦,脸上戴著一副眼镜,眼镜明亮。这就是我最喜欢的老师。
唐宋或更早之前,针对“经学”“律学”“算学”和“书学”各科目,其相应传授者称为“博士”,这与当今“博士”含义已经相去甚远。而对那些特别讲授“武事”或讲解“经籍”者,又称“讲师”。“教授”和“助教”均原为学官称谓。前者始于宋,乃“宗学”“律学”“医学”“武学”等科目的讲授者;而后者则于西晋武帝时代即已设立了,主要协助国子、博士培养生徒。“助教”在古代不仅要作入流的学问,其教书育人的职责也十分明晰。唐代国子学、太学等所设之“助教”一席,也是当朝打眼的学官。至明清两代,只设国子监(国子学)一科的“助教”,其身价不谓显赫,也称得上朝廷要员。至此,无论是“博士”“讲师”,还是“教授”“助教”,其今日教师应具有的基本概念都具有了。

课本、报刊杂志中的成语、名言警句等俯首皆是,但学生写作文运用到文章中的甚少,即使运用也很难做到恰如其分。为什么?还是没有彻底“记死”的缘故。要解决这个问题,方法很简单,每天花3-5分钟左右的时间记一条成语、一则名言警句即可。可以写在后黑板的“积累专栏”上每日一换,可以在每天课前的3分钟让学生轮流讲解,也可让学生个人搜集,每天往笔记本上抄写,教师定期检查等等。这样,一年就可记300多条成语、300多则名言警句,日积月累,终究会成为一笔不小的财富。这些成语典故“贮藏”在学生脑中,自然会出口成章,写作时便会随心所欲地“提取”出来,使文章增色添辉。以上就是为大家整理的四年级寒假生活指导答案,希望对大家有所启发!

二.双基导航
1-5 CCDAB
(6)1;-6;7(7)k≤2(8)①③(9)3/4(10)略
(11)解:设应降价x元.(40-x)(20+2x)=1200
解得x1=10(舍去)
x2=20
∵为了尽快减少库存
∴答:每件衬衫应降价20元.(12)解:①∵方程有两个不相等的实数根
∴b2-4ac>0 ∴(-3)2-4(m-1)>0
∴m<13/4
②∵方程有两个相等的实数根时
b2-4ac=0 ∴(-3)2-4(m-1)=0
∴m=13/4
∴一元二次方程为x2-3x+9/4=0
∴方程的根为x=3/2
(13)解:①10次:P=6/10=3/5;20次:P=10/20=1/2;30次:P=17/30;40次:P=23/40
②:P=1/2
③不一定
(14)解:设 x2+2x=y ∴y2-7y-8=0
∴y1=8 y2=-1
∴当y=8时,由x2+2x=8得x1=2 x2=-4
当y=-1时,由x2+2x=-1得x=-1
(15)① 2x2+4x+3>0
2(x2+2x)>-3
2(x2+2x+1)>-3+2
2(x+1)2>-1
(x+1)2>-1/2
∵(x+1)2≥0
∴无论x为任意实数,总有2x2+4x+3>0
②3x2-5x-1>2x2-4x-7
3x2-2x2-5x+4x-1+7>0
x2-x+6>0
x2-x>-6
(x-1/2)2>-23/4
∵(x-1/2)2≥0
