跳广场舞用英语怎么说？ 地道的

Should square dancing be forbidden ?
In recent years, square dancing has been becoming increasingly popular in cities. Many people have a habit of dancing to music with others. However, the loud noise disturbs the people who live around the square. Should square dancing be forbidden ?
I don’t think so. Here are the reasons. First of all, dancing is a good way to take exercise, which can help people to build themselves up. It also provides a chance for people to communicate with each other. Besides, the square is a good place for people to work out.
At the same time, the people living near the square have the right to live in peace. So I suggest the time when people dance on the square should be limited.

解题思路：噪声的防治主要从三种方式上来进行：一是在声源处减弱，二是在传播过程中减弱，三是在接收处减弱．生活中有很多具体防治噪声的方法，和其他选项的内容无关．

城区内某些路段禁止汽车鸣笛、住宅区道路两旁植树造林、跳广场舞的人要把音量调小一些，都是为了减小噪声污染．
故选C．

考点点评： 题目中选择项提到的说法本身都没有错误，在此题中选择项是否正确，要看其与题目中的措施能否对应上．

B

The team dance on the square is very popular with the old

翻译为英文：
Square dance is too loud.
望采纳!

解题思路：防治噪声的途径，从三方面考虑：①在声源处；②在传播过程中；③在人耳处．

把音响的音量调小是在声源处减弱噪声．
故选：A．

考点点评： 此题考查了控制噪声的三种途径，是一道声学基础题．

名词：Sqaure dance
动词：to dance in the square

We can see lots ladies dancing in the square or open spaces after dinner time.It was a very harmonious scene not until someone fire guns and release his dogs to threaten these ladies to escape,just because their music is too loud.Some people think this lousy music has seriously affecting their life,so that the dancing lady should be expelled from public place.While I can’t agree with them.I have two reasons to support my views.In the first place,most dancing ladies are retired woman,they finally have extra time to do something they like to do,and get together to dance,making more new friends who are share the same habit with them,and build up their body as well.As a matter of fact,some dancing lady is a loner with on family member at home,dancing group is like their second home.We should not deprive them of dance right.As a consequence,we cannot expel the dancing lady,because it is a public place,and why can’t we show some mercy to a group of retired lady who are just need a place to dance together?

8*15=90..

很高兴能为您排忧解难~
提上说,横竖减少了一排,那么就可以看做是横排减少了x人,竖排就减少了（x-1）人,这是因为横排的第一个也要算在竖排上.那么口算一下的话,就是横排减去了9人,竖排减去了8人.由于是方阵所以就是9乘9,得出原来人数是81个人

解题思路：（1）从环保角度来讲，一切影响人们正常工作、休息、学习和生活的声音都属于噪声；从心理角度来讲，人们不喜欢、不需要的声音就是噪声．
（2）减弱噪声的三个途径：在声源处减弱噪声；在传播过程中减弱噪声；在人耳处减弱噪声．

答：（1）对于跳舞者来说动听的广场音乐，对附近的居民是噪音，因为它干扰了人们的正常的学习和休息．
（2）①要求跳舞者减小音乐的音量，在声源处减弱噪声；
②拉上窗帘，关上窗户，在传播过程中减弱；
③戴上耳塞，在接收处减弱噪声．

点评：
本题考点： 噪声及来源．

考点点评： 本题主要考查学生对噪声的定义的理解和掌握，概念性的考查，是中招的热点．

解题思路：（1）用1减去A，D，B，E的百分比即可，运用A的百分比乘360°即可．
（2）用不关心的人数除以对应的百分比可得．
（3）求出25-35岁的人数再绘图．
（4）用14万市民乘C与D的百分比的和求解．

（1）m%=1-33%-20%-5%-10%=32%，
所以m=32，
A区域所对应的扇形圆心角为：360°×20%=72°，
故答案为：32，72．

（2）一共调查的人数为：25÷5%=500（人）

（3）500×（32%+10%）=210（人）
25-35岁的人数为：210-10-30-40-70=60（人）


（4）14×（32%+10%）=5.88（万人）
答：估计本地市民中会有5.88万人给出建议．

点评：
本题考点： 条形统计图；用样本估计总体；扇形统计图．

考点点评： 本题主要考查了条形统计图，扇形统计图和用样本估计总体，解题的关键是把条形统计图和扇形统计图的数据相结合求解．

Some students think that the square dance music caused by serious noise, has affected people's life and learning, should be banned

无！……好吧帮帮我我没有……可以要百度的墙角数枝梅，凌寒独自开。”几百年前的王安石挥笔写下这句诗时，有谁知天寒几分，冰冻几尺，花开几朵?只是当那“遥知不是雪，为有暗香来”的历史回声从孩子们口中诵出时，我们才知道那逝去的岁月留下来的，竟依旧熠熠生辉。 无赏花自开，非晴水亦明。在残酷的现实中，要有高洁的梅花，挺直自己的傲骨绽放，让淡淡的香飘散在空气里，在狭小的历史里延伸出不屈的、执着的精神脉络，着实...

解题思路：（1）根据杠杆的平衡条件进行计算求出抬起拉杆的力．
（2）音响正常工作时消耗电能得到声能；
（3）滑动变阻器的原理是靠改变连入电路中电阻线的长度来改变电阻的．由欧姆定律可知，当滑动变阻器改变了电路中的电阻，电源电压不变，所以就改变了电流．

（1）抬起拉杆的力F为动力，物品的重力为阻力，由杠杆的平衡条件：F_动×L_动=F_阻×L_阻，可求得F_动=
L阻
L动F_阻=[1/5]×200N=40N；
（2）正常工作时的消耗的电能得到声能；
（3）便携式音响中使用的音量旋钮实质是滑动变阻器（或电位器），滑动变阻器是靠改变连入电路中电阻线的长度来改变电阻的，从而改变电路中的电流，以达到控制音量的目的．
故答案为：40；声；变阻器（或电位器）．

点评：
本题考点： 杠杆的平衡条件；变阻器；电功的实质．

考点点评： 本题考查杠杆知识、变阻器、半导体和导体的有关问题，考查的知识点比较多，主要考查学生对所学物理知识的综合应用能力．
