寒假学习计划
一、早晨合理安排30分钟读一读英语。
二、利用上午2节课的时间分别独立完成2科寒假作业。
三、中午适当午休
四、和上午一样，利用下午的时间做些寒假作业，但不可一下子贪多。要均衡、科学安排。
五、自由时间可以干一些喜欢的事情，但要控制在半小时的时间。
六、晚饭之前是自由活动的时间，可以看电视等，但要看看新闻。
七、读一些好的小文章，写日记或是读后感，或是精彩的摘抄。
八、每天学习时间最少保持在7-8小时(上课时间包括在内)
九、学习时间固定在：上午8：30-11：30，下午14：30-17：30;晚上19：30-21：30。
十、既不要睡懒觉，也不要开夜车。
十一、制定学习计划，主要是以保证每科的学习时间为主。若在规定的时间内无法完成作业，应赶快根据计划更换到其他的学习科目。千万不要总出现计划总是赶不上变化的局面。
十二、晚上学习的最后一个小时为机动，目的是把白天没有解决的问题或没有完成的任务再找补一下。
十三、每天至少进行三科的复习，文理分开，擅长/喜欢和厌恶的科目交叉进行。不要前赶或后补作业。完成作业不是目的，根据作业查缺补漏，或翻书再复习一下薄弱环节才是根本。
十四、若有自己解决不了的问题，千万不要死抠或置之不理，可以打电话请教一下老师或同学。
寒假日记
写完作业了，我和往常一样出去玩。走着走着，我发现了一个蜗牛，我就捉了一只把它带回家放在一个小盒子里认真观察起来。
蜗牛的背上背着一个漂亮精致的“小房子”，身体就藏在这个房子里。我把蜗牛放在了温暖的阳光下，它们很快就从用薄膜封闭着的“门洞”里出来了，它的头部有一对螺旋形的触角，对外界刺激有敏感的反应。我轻轻触了一下，蜗牛的头立刻缩回去了，半天才又小心地探出头来。
蜗牛的嘴在哪儿呢?我找来一个放大镜仔细地看才发现一个很小的圆点，我想蜗牛一定吃得很慢。于是我做了一个实验。我拿来一片菜叶放在盒子里，把蜗牛捉来让它吃。我等了好长时间也没有看到它吃菜叶，我就把盒子盖严，去睡午觉了。
当我醒来的时候，我吃惊地发现蜗牛把叶子快吃完了。但我始终没有看见它吃东西 ，我想它可能是在黑暗中吃吧。我再仔细一看，盒子里有许多黑色的小颗粒，放菜叶时并没有这些东西，那一定就是蜗牛的排泄物了。我大概睡了三个小时，这说明蜗牛是在黑暗中吃东西，而且吃得很慢。 我还发现蜗牛爬过的地方留下一道白色的痕迹，在阳光下闪烁。
蜗牛真是一种神奇的小动物，特别是他那背在背上的保护着它的“小房子”，让我觉得非常有趣。

寒假作文500字
今天早上，我刚醒来，就听爸爸说：“哇!地上积了好厚的雪!”我有点不相信--昨天晚上又打雷又闪电的，怎么会下雪呢?我满腹狐疑地穿好衣服，往窗外一看，呀!真的下雪了!树上披上了银装，大地一片洁白。真是“忽如一夜春风来，千树万树梨花开”。在洁白的雪地上，看不见人的脚印。我想：看来人们都还在床上睡觉呢--不然，怎么会没有脚印?
我马上把妈妈拉起来，让妈妈陪我到楼下玩雪。结果，我发现地上不是软软的雪，而是坚硬的小冰粒。地上很滑，人们穿着平底鞋在雪地上走，当然不会留下脚印。这种小雪粒，根本不能打雪仗或者堆雪人。哎!好不容易盼到了雪，却玩不成。而且由于地上太滑的缘故，我和妈妈走路也小心翼翼的，真倒霉!
回到家，我问爸爸：“为什么昨夜打雷闪电后还会下冰雹--不是一般会下雨吗?”爸爸想了想说：“可能是因为在空中飘浮的小水珠，碰上了极强的冷空气，就变成了小冰粒。”
这场雪虽然给我一次视觉盛宴，但却不能玩雪，还是挺懊丧的!

一、1、误差<1m X约等于6 误差<0.1m X约等于5.3 2、(2)2×3-1×2×0.5×2-1×3×0.5=6-2-1.5=2.5 二、CD 三、2、4
四、证明：因为OP是∠AOD和∠BOC的平分线 所以∠AOP=∠DOP,∠BOP=∠COP
即∠AOD-∠BOP=∠DOP-∠COP 所以∠AOB=∠COD 在三角形AOB和三角形COD中
OA=OC ∠AOB=∠COD OB=OD 所以三角形AOB全等于三角形COD 所以AB=CD
