明清时期，湖州始终是全国制笔业的中心，所出湖笔深受文人的喜爱。

（1）对爱因斯坦光电效应方程，下面的理解正确的有  （    ）

A．用同种频率的光照射同一种金属，因为电子逸出功相同，所以金属中逸出的所有光电子都会具有同样的初动能

B．用同种频率的光照射同一种金属，因为电子逸出功不同，所以金属中逸出的光电子的初动能出现差别

C．逸出功和极限频率之间应满足关系式

D．光电子的最大初动能和入射光的频率成正比，与入射光的强度无关⑵质量为M的木板若固定在光滑的水平地面上，质量为m的子弹以速度v₁射入，射出时子弹速度v₂，如图所示，今将钉子拔掉，则子弹至少多大速度才能射穿木块？（设前后两次子弹和木块的作用力相同）

　　①记得有一次，幼小的我忽然走到母亲面前，仰着脸问道：“妈妈，你到底为什么爱我？”母亲放下针线，温柔地、不迟疑地说：“不为什么——只因为你是我的女儿！”

　　②我不相信世界上还有人能说这句话！“不为什么”这四个字，从她口里说出来，何等刚决，何等无回旋！她爱我，不因为我是名人。她的爱是不附带任何条件的。总之，她的爱，是屏除一切，拂拭一切，层层地挥开我前后左右所蒙罩的，使我成为“今我”的元素，而直接地来爱我自身。

　　③天上的星辰，骤雨般落在大海上，嗤嗤繁响。海波如山一般的汹涌，一切楼屋都在地上旋转，天如同一张蓝纸卷了起来。树叶子满天飞舞，鸟儿归巢，走兽躲到它的洞穴。万象纷乱中，只要能找到她，我相信，她对我的爱，不因万物的毁灭而变更。

　　④她的爱不但包围着我，而且普遍地包围着一切爱我的人；而且因为爱我，她也爱了天下的儿女，她更爱天下的母亲。

HOW would you like to step into the world of other people’s dreams? That’s just what Dom Cobb (Leonardo DiCaprio) does. His work is to steal secrets from people when they are asleep and dreaming. He has an even rarer ability: He can plant an idea in someone’s sleeping mind, and watch it grow and take root in reality. This ability is called inception.

The movie Inception (《盗梦空间》) was on show in Chinese cinemas not long ago. It is imaginative, of course. The movie leads one to wonder just how much we know about dreams. For years, scientists and researchers have been trying to solve sleep’s greatest mystery.

Is it possible to enter someone’s dreaming mind? In the movie, DiCaprio uses a drug and a dream machine to put a scenario (某一特定情节) into someone’s sleeping mind. He then goes to sleep himself, connected to the machine, and enters the other person’s dream.

In real life, there is a machine that can read someone’s mind. A brain scanner takes pictures of brain activity, and then the software recreates images of what the person was looking at.

Researchers say it may be possible one day to record someone’s dream – without the danger (or the fun) of actually sharing that dream.

What’s a dream, anyway? A dream is a group of images and sounds our brain creates when we’re sleeping. In the 1950s, researchers discovered a sleeping condition that happened around every 90 to 120 minutes during sleep: rapid eye movement, or REM. During this period you’re fast asleep, yet your eyes move around quickly under your eyelids (眼皮) and your brain is nearly as active as during the day. That’s when most dreams happen.

What do dreams mean? Dreams are not always filled with meaning. Sometimes dreams are just your mind playing with thoughts and images from your life, or things you may have read or seen on TV. But at other times, dreams show things that you want to achieve in real life, or things that cause you trouble or stress.
