1.A每件需要150元.B每件需要130元
2.B获利最大,最大利润到180元.

解题思路：由各长方形的高的比得到各段的频率之比，即可得到第二组的频率，再由数据总和=某段的频数÷该段的频率计算作品总数．

从左至右各长方形的高的比为2：3：4：6：1，
即频率之比为2：3：4：6：1；第二组的频率为[3/16]，第二组的频数为9；
故则全班上交的作品有9÷[3/16]=48．
故答案为：48．

点评：
本题考点： 频数（率）分布直方图；频数与频率．

考点点评： 本题考查分析频数分布直方图和频率的求法．解本题要懂得频率分布直分图的意义，了解频率分布直分图是一种以频数为纵向指标的条形统计图．

English Opera Festival
Last week, the English Opera Festival has been held in our school. It was on December 31 ^st . All the teachers and the students attended it at the school gym. The purpose of this festival is to improve the interest of learning English，show the talents of the students’ and strengthen the communication between the classes. At the festival, the students performed the famous foreign opera, such as The Phantom of the Opera, Cinderella and so on. The performance is very wonderful and the costume is beautiful. The music was very moving and the pronunciation was very perfect. I think the festival is a success. And it is good for our students to learn English well.

Our Art Festival “Work while you work and play while you play, this is the way to be happy and gay. ”The .Art Festival① held in our school let us have a good time after the hard work of a long term .On Friday afternoon at the end of last term, our class, that is, Class 5 of Senior Two, had a wonderful party to celebrate this happy festival. First we had music and dance----piano sonata②, exciting songs, brilliant waltz③ dance, then most popular disco④ music, etc, ---- all this made us extremely happy. Then we had one competition after another. It was soon about five o'clock before we knew it. The most exciting program began: Cooking Competition . Each group of our class had to make some special dishes . At once students became cooks, though they coudn't tell the salt from gourmet powder⑤ the day before. At seven o'clock all dishes were ready.“Ah, it tastes wonderfully delicious,”someone shouted. Then here and there applause was heard. At last we had to finish our party . When we said good-bye to each other, we had the same feeling in our hearts: “We wish to have more and more of such wonderful time in our school life. We young students need to be happy after our lessons . Our life should be filled with joy.”
满意请采纳

解题思路：（1）声音的三个特征分别是：音调、响度、音色，是从不同角度描述声音的，音调指声音的高低，由振动频率决定；响度指声音的强弱或大小，与振幅和距离有关；音色是由发声体本身决定的一个特性．
（2）声音的传播需要介质，固体、液体、气体都可以传声．

A、声音的传播需要介质，乐曲的声音是通过空气传入人耳的，故A正确；
B、变换手指按压弦的位置可以改变声音的音调，故B错误；
C、用力拨动吉他弦可以提高声音的响度，故C错误；
D、拨动不同的吉他弦可以改变吉他的音调，故D错误．
故选A．

点评：
本题考点： 音调、响度与音色的区分；声音的传播条件．

考点点评： 本题考查了学生对声音的三个特性--音调、响度、音色以及声与能量的掌握，属于声学基础知识的考查，比较简单．

1.5÷7.5×8=1.6米

解题思路：（1）根据条形图以及扇形统计图得出调查的总人数，进而利用加权平均数求法得出即可；（2）利用（1）中所求得出各组人数画出条形图即可；（3）利用树状图表示出所有可能，进而利用概率公式求出即可．

（1）本次调查的学生总数：8÷40%=20；
评分为一般的人数：20×20%=4，
评分为有待改进的人数：20-4-6-8=2，
平均分：（8×4+6×5+4×3+2×2）÷20=3.9；
故答案为：20，3.9；

（2）如图所示：

（3）评价为“一般”的男同学B₁，女同学为：C₁，C₂，C₃；
评价为“有待改进”的男同学B₂，女同学为：C₄；
画树状图得：

∴由表可知都是女生的概率为：[3/8]．

点评：
本题考点： 条形统计图；扇形统计图；列表法与树状图法．

考点点评： 此题主要考查了树状图法求概率以及扇形图与条形图的综合应用，将扇形图与条形图有机的结合是解题关键．

Do they have an Art Festival on the Friday?

设甲购x件乙购x+2丙购y,
3x+2(x+2)+y=66
x大于等于10
3x小于等于66/2
所以x为10或11
5x+y=62
x=62-y/5
x=10时y=12 x=11时y=7
因此：2种方法
第一种：甲买10个 乙12个 丙12个
第二种：甲11个 乙13个 丙7个

We willl hold a Art Festival on the playground.
活动的名字就叫艺术节么?总觉得怪怪的,没法,我也只能这么翻译了,我用的是将来时

小剧本-----小红帽 Little Red Riding Hood 第一场：Little Red Riding Hood家 Mum： (妈妈拿着一个篮子,把桌子上的水果放在篮子里） Little Red Riding Hood:(唱着歌,欢快地跑进来）Hi,mummy, what are you doing?...

校团委在全校范围广泛征集艺术节的活动建议

兴高采烈（手舞足蹈）、（载歌载舞）、（喜上眉梢）、（兴致勃勃）、（心花怒放）
一丝不苟（精益求精）、（小心谨慎）、（小心翼翼）

解题思路：①声音是物体振动产生的，一切发声体都在振动；
②声音传播需要介质，声音可以在气体、液体和固体中传播，真空不能传声；
③声音的强弱叫响度，响度与发声体的振幅有关，振幅越大，响度越大．

在学校艺术节活动中．同学们用大小不同的盘子，敲击出悦耳动听的声音．这个声音是由盘子的振动产生的，现场观众听到的声音是通过空气传播的，用不同的力敲击同一个盘子，振幅不同，发出声音的响度不同．
故答案为：振动；空气；响度．

点评：
本题考点： 声音的产生；声音的传播条件；响度与振幅的关系．

考点点评： 此题考查的是声音的产生、传播条件以及物理特征之一--响度的影响因素，属于声现象中的重点内容，但难度不大．

We will have an art festival next month

可以这样做：20×11-18×12＝4（人）

解题思路：①中位数是将一组数据从小到大（或从大到小）重新排列后，最中间的那个数（最中间两个数的平均数），叫做这组数据的中位数；众数是指一组数据中出现次数最多的数据；
②在此组数据中最高分是9.8，最低分是6，把此两个分数去掉，再算出剩下的8个数的和，再除以8就是要求的平均数；
③根据中位数的意义即可求解．

①排序：9.2，9.3，9.4，9.5，9.5，9.5，9.5，9.6，9.8，9.9，中位数：（9.5+9.5）÷2=9.5，众数：9.5．&...

点评：
本题考点： 中位数的意义及求解方法；平均数的含义及求平均数的方法；众数的意义及求解方法．

考点点评： 解答此题应结合题意和中位数和众数和平均数的计算方法进行解答即可．

解题思路：设购买甲纪念品为x元，则乙为（x+2）元，由于甲、乙、丙三种纪念品恰好用了66元钱，则买甲、乙两种纪念品的钱≤66，再根据甲种纪念品的件数不少于10件，且购买甲种纪念品的费用不超过总费用的一半，列不等式解答．

设买甲种纪念品数量为x，丙种纪念品数量为y，
则乙种纪念品数量为（x+2），
则3x+2（x+2）+y=66，
即y=62-5x，
又x≥10且3x≤[66/2]，
解得x≤11，
∴x=10或11，即2种方案：
当x=10时，x+2=12，y=62-5x=12；
此时甲乙丙3种纪念品分别为10，12，12．
当x=11时，x+2=13，y=62-5x=7，
此时甲乙丙3种纪念品分别为11，13，7．

点评：
本题考点： 一元一次不等式的应用．

考点点评： 本题考查一元一次不等式组的应用，将现实生活中的事件与数学思想联系起来，读懂题意，根据甲、乙、丙纪念品的数量及价格列出不等式即可求解．
