海安的七星湖公园风景秀丽如画,让人流连忘返.盛夏时节,湖水减弱了周围地区的“热岛效应”.这是利用湖水的______来吸热从而降低了周围空气的温度;美丽的廊桥在水中的倒影,是经过光的______所形成的______像(填“实”或“虚”).

答案

(1)水在蒸发过程需要吸收热量,故周围温度会降低,从而减弱了周围地区的“热岛效应”.

(2)光发生折射的条件是:当光从一种透明介质斜射入另一种透明介质时,会发生折射现象;鱼反射的光斜射向水面时,由光发生折射的条件知,会发生折射现象,当光进入水中后靠近法线,射入我们的眼睛,而我们由于错觉,认为光始终沿直线传播,逆着光的方向看上去,看到鱼的虚像,而且比实际位置高.

故答案为:蒸发;反射、虚.

In the middle of a dark forest, there lives an owl(猫头鹰). All the animals know that he is the wisest(聪明的) among all of them. So they often go to him and tell him their troubles. Then the owl always teaches them what they should do.

One day, a little bird goes up to the owl. She is crying. “what’s wrong with you?” asks the owl.

“I’m not happy at all. I don’t want to be a bird,” the bird says.

“Why don’t you want to be a bird?” asks the owl.

“I am so small, weak and useless,” she cries. “I want to be big and strong like the lion. He is very important, but I am not”

Then the owl whispers(耳语) something in her ear. At once the bird dries her tears and goes away. One week later, the bird came back. “Oh, thank you very much. You are a very wise owl,” she says to the owl. “I am very happy now. Every day, I sit on top of the tallest tree and watch for(监视) lions and tigers. When they come near, I shout at the top of my voice. Then my friend all run and hide. They are very thankful to me. I am useful and important now”

The wise owl smiles and says, “No one in this world is useless.”
