The park bench was deserted as I sat down to read beneath a tree. It must be sick, for the branches were kind of yellow and dry. I was a deserted girl. A failure in an exam made me sad and I just wanted to stay alone. As I sat on the bench, things that happened recently began to flash through. No one to talk to. Not content with life, I had a good reason to frown.

Suddenly, a young boy out of breath approached me, all tired from play. He stood right in front of me with his head tilted (倾斜) down and said with great excitement, “Look what I found!” In his hand was a flower. What a pitiful sight, its petals (花瓣) were all worn—not enough rain, or too little light. He must have picked the flower from somewhere shady and sunless, just like where I was staying these days. Wanting him to go off to play, I smiled at him and then looked away. “Why couldn’t everyone just leave me alone!” I thought to myself.

But instead of leaving, he sat next to me and placed the flower to his nose and declared loudly with certainty, “It sure smells pretty and it must be beautiful, too. That’s why I picked it; here, it is for you. ”The flower before me was not vibrant with colors, orange, yellow or red—anyone can see that clearly! But I knew I must take it, or he might feel sad. So I reached for the flower, and replied, “Just what I need.” Strangely, instead of placing the flower in my hand, he held it in mid-air without any reason or plan.

Casting a curious glance at the boy’s eyes, I was hugely shocked. In the pure and sunny face were just a pair of eyes, somewhat hollow and focusless. “He was blind!” I felt myself choked as if there were a lump in my throat.

With watery eyes, I took the flower from his hand carefully and praised it as the very best one.

I’d been waitressing for months, earning extra money for college. “Since it’s not too busy, go and see if Ray wants any more coffee,” my boss said to me as he pointed to an older man sitting in the corner.

Ray was holding the cup in his hand as he stared out of the window. He was a re gular lunch customer on Mondays and Fridays.

“Can I refill the cup for you, Ray?” I asked. He looked up with a peaceful smile and held his cup out toward me. “You know, I’ve been coming here for several years, and I have to say you have the nicest smile,” he whispered. “Can you sit for minutes... please?”

I sat down and he smiled,   “Your smile reminds me of my granddaughter, Sharon.” He took out a picture of her from his wall et and handed it to me. “She graduated from college last year.”

“What a nice-looking girl!” I said. “Does she live near you?”

Ray shook his head as he put the picture back in his wallet. “She moved to California last year. I miss her a lot. She and I used to have lunch together on Monday s and Fridays,”   he said. “She now wants me to move out there to be closer to her.”

“So, why don’t you?”

“I don’t know if I really want to move. I’ve been here all my life,” he answered.

I heard my boss calling me. “I guess that’s meant for me,” I said as I stood up.

We smiled at each other. “Ray……if my grandfather had been like you, I’d have asked him day and night to move closer to me, too.”   I patted his shoulder. “Don’t wait too long. Nice talking with you...”

For the next couple of weeks, Ray continued to come on Mondays and Fridays. But on that Monday of Thanksgiving week, he didn’t show up. Then one Wednesday afternoon, walking out to my car after work, I heard a voice call my name from across the parking lot.

It was Ray, hurrying to catch up to me.

如图，竖直平面内一足够长的光滑倾斜轨道与一长为的水平轨道通过一小段光滑圆弧平滑连接，水平轨道右下方有一段弧形轨道。质量为的小物块A与水平轨道间的动摩擦因数为。以水平轨道末端点为坐标原点建立平面直角坐标系，轴的正方向水平向右，轴的正方向竖直向下，弧形轨道端坐标为，端在轴上。重力加速度为。

电容器作为储能器件，在生产生活中有广泛的应用。实际中的电容器在外形结构上有多种不同的形式，但均可以用电容描述它的特性。
(1)在两个相距很近的平行金属板中间夹上一层绝缘物质就组成一个最简单的电容器，叫做平行板电容器。图1为一平行板电容器的充电电路，在充电过程中两极板间电势差u随电荷量q的变化图像如图2所示。类比直线运动中由v—t图像求位移的方法，在图中画网格线表示当电荷量由Q₁增加到Q₂的过程中电容器增加的电势能；
(2)同平行板电容器一样，一个金属球和一个与它同心的金属球壳也可以组成一个电容器，叫做球形电容器。如图3所示，两极间为真空的球形电容器，其内球半径为R₁，外球内半径为R₂，电容为，其中k为静电力常量。请结合(1)中的方法推导该球形电容器充电后电荷量达到Q时所具有的电势能E_p的表达式；
(3)孤立导体也能储存电荷，也具有电容：
a.将孤立导体球看作另一极在无穷远的球形电容器，根据球形电容器电容的表达式推导半径为R的孤立导体球的电容的表达式；
b.将带电金属小球用导线与大地相连，我们就会认为小球的电荷量减小为0。请结合题目信息及所学知识解释这一现象。

激光束可以看作是粒子流，其中的粒子以相同的动量沿光传播方向运动。激光照射到物体上，在发生反射、折射和吸收现象的同时，也会对物体产生作用。光镊效应就是一个实例，激光束可以像镊子一样抓住细胞等微小颗粒。一束激光经S点后被分成若干细光束，若不考虑光的反射和吸收，其中光束①和②穿过介质小球的光路如图所示。图中点是介质小球的球心，入射时光束①和②与的夹角均为，出射时光束均与平行。小球折射率大于周围介质的折射率，不考虑光的吸收和反射，光对小球的作用力可以通过光的折射和动量定理分析，关于两光束因折射对小球产生的合力分析正确的是（　　）
