Lie in bed, by an open window, and listen…

“No air conditioning? How can you sleep?” a friend asks, horrified. I tell her my family has decided to shut the air conditioner off and reduce our electric bill. On this first night of our cost-cutting plan, it’s only 85 degrees. We’re going to suffer, but the three kids complain anyway.

They have grown up in 72-degree comfort, protected from the world outside.

“It’s too hot to sleep,” my 13-year-old daughter complains. “I’m about to die from this heat,” her brother complains down the hall. “Just try it tonight,” I tell them. In truth I’m too tired to turn for long. My face is sweaty, but I lie quietly listening to the cricket choirs outside that remind me of childhood.

The neighbor’s dog howls. Probably a passing squirrel. It’s been years since I took the time to really listen to the night.

I think about grandma, who lived to 92 and still helped with my mom’s gardening until just a few weeks before she died. And then, I’m back there at her house in the summer heat of my childhood. I move my pillow to the foot of grandma’s bed and turn my face toward the open window. I turn the pillow, hunting for the cooler side.

Grandma saw me turn over and over. “If you just watch for the breeze(清风),” she said, “you’ll cool off and fall asleep.” I stare at the filmy white curtain, willing it to move. Lying still, waiting, I suddenly notice the life outside the window. The bug chorus. Neighbors, porch(门廊)-sitting late, speak in unclear words that calm me.

“Mom, did you hear that?” my seven-year-old son cries, “I think it was an owl(猫头鹰)family.”

“Probably,” I tell him, “just keep listening…”

Without the working air conditioner, the house is peaceful, and the natural night noises seem close enough to touch. I hope I’m awake tonight when the first breeze comes in.

简介辐射杂交细胞系（RH）技术的原理。

材料一1859年11月3日，达尔文的科学名著《物种起源》出版了。这一天，伦敦街头的几家书店门前，人声鼎沸，挤满了许多前来购买这本刚出版的新书的读者。初版的1250册新书，当天就被争购一空。这本观点新奇、内容独特的著作一出版，立即在英国掀起轩然大波：有些人兴高采烈，拍手称赞；有些人恼羞成怒，暴跳如雷；更多的人则把它当成奇闻传说，到处宣扬。材料二1860年6月30日，关于进化论大论战的第一个回合，在牛津大学面对面地展开了。以赫胥黎、胡克等达尔文学说的坚决支持者为一方，以大主教威尔伯福士率领的一批教会人士和保守学者为另一方……面对威尔伯福士之流的恶毒攻击和挑衅责难，赫胥黎说道：“我要重复地断言，一个人有人猿为他的祖先，这并不是可羞耻的事。可羞耻的倒是这样一种人：他惯于信口雌黄，并且不满足于他自己活动范围里的那些令人怀疑的成就，还要粗暴地干涉他根本不理解的科学问题。所以他只能避开辩论的焦点，用花言巧语和诡辩的辞令来转移听众的注意力，企图煽动一部分人的宗教偏见来压制别人，这才是真正的羞耻啊！”材料三在美国，1981年阿肯色州通过一个法案，“公立学校可以用教进化论同样的时间教神创造论”。1982年美国自由公民联盟控告阿肯色州政府违宪，闹到最后，1987年7月，美国高等法院7︰2票反对教神创造论。

综合材料一、二、三，你能得出什么启示？
