“率”从其字源来说是独体字结构.
它属于象形文字,甲骨文字形,像捕鸟的丝网.本义就是捕鸟的丝网.

如果设宇航员在月球上重x,那么由于第一句话知道其在地球上重量是6x,那么6x-x=80,即5x=80.x=16.则在地球上是6x=6*16=96kg

我试试!
四月份生产机床总台数为W=250+150+200=600
所以,
上旬占的比例为250/600=5/12
中旬占的比例为150/600=3/12
下旬占的比例为200/600=1/3

下册：（83-4.3+2.6）/3=27.1元；上册：27.1+4.3=31.4元；中册：27.1-2.6=24.5元。

解题思路：（1）首先知道“频闪摄影”时，摄影的时间间隔是相同的；（2）物体的运动路线是直的，在相等的时间内通过的路程相同，物体进行的是匀速直线运动，物体的运动路线是直的，在相同的时间内通过的路程不相同，物体进行的是变速直线运动；（3）动能和势能合称机械能；重力势能与质量和物体所在高度有关；（4）物体在平衡力的作用下，运动状态不变；物体受到的不是平衡力，运动状态一定改变．

A、由图知，甲球是两个时间间隔，乙球是4个时间间隔，所以甲球与乙球运动的时间之比为1：2．此选项正确；
B、乙球下落过程中，质量不变，高度减小，所以重力势能减小；速度不变，动能不变，所以机械能减小．此选项正确；
C、在相同时间，甲球通过的距离不相等，也就是速度发生变化，说明力可以改变物体的运动状态；而乙球速度不变，运动状态没有变化．此选项错误；
D、若两球质量相等且都只受到重力和阻力作用，甲球加速运动，说明阻力小于重力；乙球匀速直线运动，说明阻力等于重力．所以所受阻力较大的是乙球．此选项正确．
故选C．

点评：
本题考点： 速度与物体运动；机械能．

考点点评： 正确读取频闪照片上反映的物理信息是解决问题的关键，照片上两个小点之间的间隙越大，说明速度越快，间隙越小，说明速度越慢．

上中格

英文的书写方法有多种,现在英语教材上的手写印刷体,f 占上中格,以前咱们上学的时候老师教的是英文斜体字,f占上中下三格,另外还有英文圆体字母

i don't know how to deal with it,go to high school or go to technical secondary school?

石块从上游到下游,依次出现以下变化：
1、体积变小（粒度变小）,上游可以是巨大的砾石,到下游可能已经变成沙子.
2、磨圆变好,上游为棱角状,到下游可能为球状.
3、分选变好

分析：
中下两层书的本数-上中两层书的本数=下层书的本数-上层书的本数=310-280=30(本)
上层书比下层少30本,少2/11,那么下层书有：30÷(2/11)=165(本)
中层书有：310-165=145(本)
综合列式：
310-(310-280)÷(2/11)=145(本)
中层书有145本.

施耐庵（约1296～1370）
中国元末明初作家.名子安,一说名耳.兴化（今江苏兴化县）人,原籍苏州.相传施耐庵是《水浒传》的作者.明嘉靖十九年（1540）,高儒《百川书志》载：“《忠义水浒传》100卷.钱塘施耐庵的本.罗贯中编次.”嘉靖四十五年郎瑛在《七修类稿》中说：此书为“钱塘施耐庵的本”.万历年间,胡应麟在《少室山房笔丛》中指出：“武林施某所编水浒传,特为盛行.”今人一致认为施耐庵是《水浒传》作者.
有关施耐庵生平事迹材料极少,搜集到的一些记载亦颇多矛盾.自20世纪20年代,江苏兴化地区陆续发现了一些有关施耐庵的材料,有《施氏族谱》、《施氏长门谱》和《兴化县续志》卷十三补遗载有《施耐庵传》1篇、卷十四补遗载有明初王道生撰《施耐庵墓志》1篇.据这些材料分析,施于元明宗至顺二年（1331）中进士,曾官钱塘二年,因与当权者不和,弃职还乡,回到苏州写作《水浒传》,追溯旧闻,闭门著述,悒悒不得行其志.还有的传说他此时与元末农民起义将领张士诚有过联系.
寓逆旅主人,日再食,无鲜肥滋味之享.
其中“逆旅”(文言),是文言的旅店,在文言文中常用.
逆旅是旅的义项之一,在逆旅一词中不能单开解释.

应该是上中下结构 我的老师也好像说过。。。

设中册价格为X元.
(X+0.43)+X+(X+0.26)=8.31
3X+0.69=8.31
3X=8.31-0.69
3X=7.62
X=2.54
上册：2.54+0.43=2.97元
中册：2.54元
下册：2.54+0.26=2.8元
答:上册2.97元,中册：2.54元,下册2.8元.

设中册用钱x元,则上册用钱（x-1.5）元,下册用钱（x+2.5）元
则（x-1.5）+x+(x+2.5)=31
解得x=10
即：上册用钱8.5元,中册用钱10元,下册用钱12.5元

上游：一般是处于高原,因为水往低处流,高原一般是河流的发源地.而且水流较小.上游流域人迹较中下游少.
中游：随着不断有支流加入,中游的水流渐渐壮大起来,而且如果河流是从高原山地发源的话,中游一般也到了平原地区了,流域两岸的人迹也渐渐多了起来.
下游：下游的水流显然比中上游更大.而且,下游就是注入大海的地方了,已经是平原,因为人类的文明发祥地是顺着水走的（如恒河流域的文明、两河流域的美达不索米亚文明、黄河长江中下游的中华文明）,所以,河流的下游流域聚居了很多的人.
以长江为例,长江从青藏高原发源,到了中游,已经下了高原进入华中的山地,再到了下游,已经是华北平原了.而且,中华文明的发祥地是在黄河下游和长江下游之间的华北平原.
可是,也有例外的.如南美洲的亚马孙河,流域几乎都是亚马孙平原.

Li Ming classmate hello
Very glad to see your help,we hope that the following analysis is helpful to you.
Your question we can be divided into two:one,before you leave home,this little home from school attached to let your pain.Second,you still can't adapt to the environment,the dormitory are not good rest.
According to the first question,which attachment.We left home to school,is a self development,is our way of hope in the growing process of the youth,the inevitable before saying "young men far!"

The problem with your first question,there must be more is your classmate acceptance degree with the problem.
We came to a new environment,to the new environment is very important,if we quickly adapt to the new life,we will be happy,positive emotions,if our flexibility is weak,we will produce angst,thoughts,emotions,such negative nostalgic affect our normal life,work and low efficiency,sleep,poor communication,etc.In our mental health adversely.
How to adapt to the new environment and accept new things?First,the new things have an idea,such as schools,we understand the nature of the school,the students' training objectives,and the characteristics of the other students,teachers and students' attitude towards when we feel we study goals and objectives of the school of training,we would be accepted and approved by the school.Understanding the characteristics of the other students and teacher's attitude,our hearts can have the preparation,and the relationship between his confidence,so we will do a pleasant performance,optimistic and positive.Secondly,we should actively participate in some collective activities.We live in the collective,we grow without education and training of the collective,we only participate in collective activity can benefit from the collective,can learn some development.So we should actively participate in collective activity,in the collective activity,let others know oneself,let yourself for success and accomplishment,the collective and the students can better,we accept us to new things.Third,we should be good at communication with the students.With classmates is a kind of art,respect and understanding,tolerance is open,the principle of communication in a relationship,we should respect each other,understand each other,actively open ego,YanYiLvJi generously,so that we can make friends,to make new friends.We have friends to share with everyone,can get help and understanding of others,we can obtain the support of others.

Hope you can quickly adapt to the school life in the school study happily,games,and let your heart with sunshine and passion

口语中up是上，Middle是中，down是下。
体操中同样适用的，所以就很简单了：up up. up middle.up down. middle up.……一次类推：和用and就好了！O(∩_∩)O~望采纳

　　提高口语的话,还是外教好一些,因为外教能够提供纯正的语言环境.
　　不过,在学习之前最好了解清楚自己的英语水平,如果水平相对较差,前期还是跟着中教学会好一些.

先求菜地的面积：
（18+28）*32除以2
=46*32除以2
=736平方米
萝卜是白菜的3倍,同可以把菜地分成4份,一份白菜,3份萝卜,就可以了.
736除以4=184平方米
184*3=552平方米
所以白菜地184平方米,萝卜地552平方米.

读图可知：57～59的五数=17+12=22五．
故本题答案为：22．

许多侍卫虽然手持兵器,但都守候在大殿之下,没有大王的命令他们是不能上殿的.
上应该是省略用法,或者是名词的动用.

希望可以帮到你,欢迎追问：）

根据题意假设下册X元,则中册比下册贵7元,为X+7元,上册比中册贵5元,为X+12元则：
4*(X+X+7+X+12)=340
3X+19=85
3X=66
x=22元
