I had a very special teacher in high school many years ago. Her husband died because of traffic accident. About a week after his death, she shared some of her insights with us.

The class was clearly over. She said,"Before class is over, I would like to share with all of you an important thought.”  “Each of us is on Earth to learn, share, love and *appreciate. We must *cherish every single day.”

Her eyes beginning to water, she went on, “So I would like you to make me a *promise. From now on, on your way to school, or on your way home, find something beautiful. It could be a *scent----perhaps of freshly baked bread, or it could be the sound of the *breeze slightly *rustling the leaves in the trees.

“Please look for these things, and cherish them. For, although it may sound * trite, these things are the *stuff of life. They are the little things on Earth to enjoy. They are the things we often take for *granted. We must try to notice them because it can be easily taken away at any time.”

The class was completely quiet. We picked up our books and went out of the room silently. That afternoon I noticed more things on my way from school than I had that whole semester.

I often think of that teacher and try to appreciate all off those things that sometimes we *overlook.

Take notice of something special you see on your lunch time today. Walk *barefoot along the beach at *sunset. For as we get older, it is not the things we did that we regret, but the things we didn’t do.

如图甲是我国某地区风力发电的外景,风力发电机组主要由风机叶片和发动机组成。

(1)风机叶片具有质量轻、强度高、耐磨损等性能,通常用密度小,硬度______(大/小)的复合材料制成;叶片形状像飞机的机翼,若叶片位置和风向如图乙所示,由于叶片两面空气流速不同产生压强差,而受到向______(上/下)的力使风叶旋转。

(2)风叶产生的动力通过传动系统传递给发电机,利用_____原理。实现机械能转化为电能。

(3)某风力发电机的输出功率与风速的关系如图丙所示,由图像得到的下列信息,正确的有哪些_____

A.只要有风,机组就能产生电能

B.风速过大,机组不会产生电能

C.风速越大,机组产生的电功率一定越大

D.风速在一定范围内,机组产生的电功率可能不变(4)下表给出了在不同风速下某风机获得的能量:

平均风速(m/s)5101520
1s内获得的能量(×104J)182764
①对表格进行分析,你发现该风机1s内获得的能量与风速的定量关系是_____________________(用文字叙述);

②当风速为5m/s时,这台风机工作1s所产生的电能可供1只“220V 100W”电灯正常工作10s,求风机发电的效率
