2024年北京101中小升初分班考试语文作文押题及范文分析1、习作ㅤㅤ童年就像一个多味瓶，酸甜苦辣尽在其中。
在成长的过程中，你可能会有勇于实践、取得成功的笑容；有面对挫折、体验失败的泪水；有遭遇尴尬、品尝不安的无奈……不管是哪一种，总会有给你留下深刻印象的画面，请你回忆一下事情的前因后果，把经过写下来。
注意要把人物当时的表现写具体。
题目自拟。
ㅤㅤ要求：能运用动作、语言、神态描写表现人物内心。
内容具体，有真情实感。
语句通顺，书写工整，400字左右。
【分析】本次习作为自命题的叙事作文，要求选择给你留下深刻印象的画面写一篇习作。
结合题目可知，所写内容应选择一个难忘的事，这件事给你一种难忘的体验，或高兴，或激动，或愤怒，或后悔，或害怕，或悲伤……回顾自己的成长历程，你是否经历过这样的场景，选择一个印象深刻或最想表达的去写。
这是一篇写事作文，写作时要将重点放在事件的叙述上，发生了什么事，你有什么深刻的体验？你的收获是什么？注意叙事六要素，将事情叙述完整，叙述时要详略得当，通过语言、动作、神态等描写刻画人物；同时要注意用到学到的修辞手法及积累的好词佳句，将作文写得生动具体，让人印象深刻。
范文：我印象最深刻的一件事我们的生活离不开秩序。
过马路、排队、校园吃饭打饭时需要排队，这些都是要有秩序。
没有了秩序，国家会乱成一团；没有了秩序，我们会生活在一个可怕的世界。
秩序能帮助我们、改善我们的生活……一个中午，明媚的阳光撒在身上，我感到暖洋洋的。
天空中不知什么时候出现了一条条像树枝一样的白云儿，给海蓝的天空做浪花。
班里的老师还没来，糖果的香气就飘了进来，让人忍不住流口水。
糖果盒被老师放到了教室中间，糖果香气比之前更浓了，我们现在只想老师让我们拿糖。
“拿糖。
”一声清晰的话传入大家的耳朵。
过了一秒，教室里沸腾起来，同学们冲着向前拿糖。
胖点的在人群里左冲右撞，用自己的身躯把别人挤走；小个子的像一只小松鼠，找到空隙就钻，但也会被人推一下……挤得我难受极了，吃过的东西都快要吐出来。

保密★启用前2023年小升初数学（新初一）重点名校入学分班考试质量检测卷（三）答案解析一．用心思考，正确填空。
（共11小题，满分19分）1．【答案】27；28。
【分析】假设都为男生，则应该有(315)−×人，男生与女生一组就相差1人，所×人，与实际相差(52315)以用除法即可求出女生有多少组，再进一步解答即可。
【解答】解：(52315)(43)−×÷−71=÷=（组)7×=（人)4728−=（人)522827答：四（1）班男生有27人，女生有28人。
故答案为：27；28。
【点评】此题属于鸡兔同笼问题，解这类题的关键是用假设法进行分析，进而得出结论；也可以用方程进行解答。
2．【分析】本题中，本金是10000元，年利率是3.75%，存期是3年，根据利息=本金×利率×存期，由此代入数据求出利息，然后用利息加上本金就是可以获得的钱数．【解答】解：1000010000 3.75%3+××+10000112511125=（元)答：到期后可以获得本息和为 11125元．故答案为：11125．【点评】这种类型属于利息问题，有固定的计算方法，利息=本金×利率×存期（注意时间和利率的对应），本息=本金+利息，找清数据与问题，代入公式计算即可．3．【答案】449511000，44951.1，4。
【分析】从高位到低位，一级一级的写，哪位没有数用0占位，改写成用万作单位的数，就是在万位数的右下角点上小数点，然后把小数末尾的0去掉，再在数的后面写上“万”字；省略“亿”后面的尾数就是四舍五入到亿位，把亿位后的千万位上的数进行四舍五入，再在数的后面写上“亿”字。
【解答】解：四亿四千九百五十一万一千写作：449511000，44951100044951.11≈亿。
=万，4495110004故答案为：449511000，44951.1，4。
