翻译的这段话很像是信件或是留言条之类,如果是信件,用XXX代替人称了哈:
Dear XXX

描绘过程的词，不能用来形容结果，改为有声有色。
“闻过则喜”指听到别人的批评就高兴，语境不符。
“评头论足”应改为“越俎代庖”。
临时抱佛脚：原意为年老信佛，以求保佑，有临渴掘井之意。后因称平时无准备而事急时仓猝张罗为“临时抱佛脚”。

Dear Peter,

本题考查成语的运用能力。A项“栩栩如生”的意思为“雕刻或绘画特别逼真”。C项中“面面相觑”表示惊讶的意思。D项“默默无闻”的意思为“不多言语或者不出名”，三项用在此处都不符合语境。

由 c=fλ c=3x10^8 m/s
得 f1=c/λ1=……=1.76x10^8 Hz=176 MHz
f2=c/λ2=……=1.67x10^8 Hz=167 MHz
仅供参考!有疑再问!

首先要知道一个公式哈：波速=波长乘频率
那么频率=波速/波长
电磁波波速在现实中近似等于光速(3*10E8m/s) 再把题目里的数据一带就好啦！~
没讲过公式那就是超纲题了 辅导书上的吧？~

解题思路：音色反映了声音的品质与特色，由于不同人的声带结构的不同，它们发出声音的音色也不一样，也是我们辨别不同声音的依据．
声音的响度和物体的振幅有关，还和距离发声体的远近有关，距离越远，响度越小；平时可以利用减少声音分散的方法来提高响度，如喊话时把手做成喇叭状放在嘴边；声音是由物体的振动产生的；声音的传播是需要介质的，它既可以在气体中传播，也可以在固体和液体中传播，但不能在真空中传播．

有一位演员模仿了二十四位著名演员的演唱与配音，惟妙惟肖，引起人们热烈掌声，这是因为他与模仿演员的音色；
医生用听诊器为病人诊病，是因为声音能传递信息，来自患者的声音通过橡皮管传送到医生的耳朵，橡胶管减少了声音的分散，提高了响度；
故答案为：音色；传递信息；响度．

点评：
本题考点： 声音的综合利用．

考点点评： 本题考查了声音传递信息的原理，提高响度的方法，声音产生的原因；与实际生活密切联系．要求平时学习时，要多联系生活、多解释，提高分析解决问题的能力．

假设小晰蜴从15cm长到20cm,体形是相似的.这时晰蜴的体重正比于它的

体积,而体积与体长的立方成正比.　 记体长为l的晰蜴的体重为 ,因此有 　 合理的答案应该是35g.

Beijing TV is going to hold a competition on "learn Chinese,sing Chinese songs" between foreigners this July. you are learning Chinese now, so you could have a try. The date of competition is on July,18th, and the deadline for signing up is June,30th. If you want to sign up, go to Beijing TV. You can know and learn more about Chinese through this activity.

This is I and the host yesterday in Beijing television program photo, I would very much like to share with you, I hope you don't mind.

f=V/λ=3*10^8/(1.1.8)=(1.67~1.76)*10^8[1/s]
应该是167~176MHz
