读了身价这个故事有什么感想把（一个农夫养了一只会说话的鹦鹉）复制到百度上去查

解题思路：本题利用老大骨头硬，光彩照人，身价百万可知为金刚石，老二又软又滑，修锁锁灵，修灯灯亮可知为石墨，老三似足球，科研工作者喜欢它为C₆₀．

A、空气中的物质不具有习题中所描述的性质，故A错误；
B、金刚石、石墨、C₆₀三者具有以上性质，三种物质是同种元素形成的不同单质，故B正确；
C、碳的氧化物不具有以上性质，则“一家兄弟”不会是碳的氧化物，故C错误；
D、金属材料不具有这“一家兄弟”的性质，故D错误；
故选B．

点评：
本题考点： 碳元素组成的单质．

考点点评： 学生应能根据物质的性质来推测是何种物质，然后来分析解答，本题应注意老三似足球，描述的物质为足球烯，是学生分析的难点．

答案积极向上即可。

世界上身价最高的动物是良种马,一岁良种赛马的最高身价是1310万美元,1985年7月23日,罗伯特•桑斯特及其合伙人在肯塔基州基是兰布以一述价格买下了名叫“西雅图舞蹈家”的赛马.

解题思路：（1）利用重力公式求出“南海一号”在水中、空气中重，利用称重法求“南海一号”受到的浮力；
（2）“华天龙”号对船的拉力等于“南海一号”在水中重，利用P=Fv求）“华天龙”号起吊该船时出水前的有用功率；
（3）知道总功率，利用η=

P有用

P总

求出水前的机械效率．

（1）“南海一号”在水中的重：
G₁=m₁g=2800×10³kg×10N/kg=2.8×10⁷N，
在空气中重：
G₂=m₂g=4800×10³kg×10N/kg=4.8×10⁷N，
“南海一号”受到的浮力：
F_浮=G₂-G₁=4.8×10⁷N-2.8×10⁷N=2×10⁷N；
（2）“华天龙”号对船的拉力：
F=G₁=2.8×10⁷N，
P_有用=Fv=2.8×10⁷N×0.1m/s=2.8×10⁶W；
（3）η=
P有用
P总=
2.8×106W
5×106W=56%．
答：（1）“南海一号”在水中所受浮力是2×10⁷N；
（2）“华天龙”号起吊该船时出水前的有用功率是2.8×10⁶W；
（3）若“华天龙”号起重船起吊时的总功率为5×10⁶W，则出水前的机械效率是56%．

点评：
本题考点： 阿基米德原理；浮力大小的计算；滑轮（组）的机械效率；功率的计算．

考点点评： 本题考查了浮力的计算、功率的计算、效率的计算，利用好称重法求浮力、功率推导公式P=Fv是本题的关键．

Actually the Chanel brand shaping is like creating music,the more you know,the man as nova more its value is higher,the performance of the greater the box office appeal.Likewise,if a consumer spent $10,000 bought a Chanel,if this brand knows,others will at once know its price,so consumer wear the out,you will feel a kind of superiority.If this brand know a fair few economists,consumer to show off the purpose is impossible to reach,change a point of view,this dress despite its price is high,also does not have performance consumer identity or wealth symbols value.Can see from this,luxury symbols value originate from its high grade,the high price of "well",but only a few people can have.From transmission Angle,to let more people know a luxury brand of high-grade is give its symbol value essential.

Nowadays,a tramp who owns only ten yuan is never destined to be unsatisfied with his life compared with a millionare who owns over hundreds of thousands of money.

有一个哲学家说过这样一句话——
想象有两个世界,一个有你,一个没有你.试着让有你的世界和没你的世界有所不同吧!
一个人的身价,在他离开的时候显示出来,也就是说,平日他是否对这个单位起到一定的作用,更主要的是看他走了之后,单位是否少了些什么.他是否影响着单位（的效率等）.

There is this Japanese mud cat (土狗土猫 什么的 只要不是纯血统 都可以用mud来表达) whom was owed by a Japanese honest old farmer. Although he is not some kind of fancy elegant cat who worth thousands of dollars, she became a the most popular superstar cat who has been chased by everyone in Japan. She is even outstanded from Japan and became known in China and even in the whole world. Now, all her fans from all over the world are eagering to communicate with him through the internet.
This cat is a male, white yellow hair. 4.5kg on weight 30cm of head circumference, waist 50cm, length 70cm. strictly speaking, he is an overweight fat cats.his head is disproportionately large. he likes squinting, wearing sunglasses.He loves tall things, and drilling small basket to sleep. The cat's name in Japanese is" basket cat". the Chinese named him "uncle cat" which is kind of cute. because he is 7 years old, which is equivalent to the age of 44 in human being's age. Calling him uncle is so right because he always seem so clam that he does not need anything from the world at all.
