Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks larger? In fact, they are exactly the same size.
Then look at the picture on the right. What do you see? A vase? Or two faces？Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.
“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret（解读）the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “visual illusion(视觉错误)”.
Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of visual illusions.
【小题1】Why does the centre circle in Diagram A look smaller than that in Diagram B?

Li Lu is a fifth-grade student who lived in a small village in Shanxi Province. She lived with her grandparents, because her parents are migrant workers in big cities. During the days when there were no school buses, Li Lu had to ride a bike five kilometers and climb a small mountain to school every day. Her 70-year-old grandfather says he and Li Lu’s grandmother always worried about her safety.
“There are so many cars on the roads, and we were really _concerned_ about her all the time. When it was time for her to come home, we would stare at the alley’s (小巷的) entrance until she showed up.”
But with the start of the new school year, the school’s new bus now picks up the students. Eleven-year-old Li Lu pointed at her seat on the bus and said ,“Now I don’t ride my bike any more. My grandparents no longer need to worry about me. The bus is spacious and comfortable. Look! This is my seat, with my name tag on the seatback.”
【小题1】How far is Li Lu’s home from her school?

For as long as I can remember, Grandma’s plentiful tomato garden has been a sign of summer’s end. Each September, just as the decreased heat of the sun suggests cooler days, Grandma requests (ask for something) my help in her tomato garden. I’m sure that she cannot pick tomatoes without my youthful eyes and quick mind. She says we need to examine each tomato and agree on its readiness for picking. While Grandma’s request for my help in the tomato garden is always the same, her desire for my help seems to increase each year.
　　Grandma has eyes for finding even the tomatoes hidden by undergrowth and other tomatoes. I, however, just turn circles looking for the ones I think Grandma will like. I spot what looks like a ripe（成熟的）tomato, head in its direction, and then get sidetracked by another that appears to be equally ripe. I usually end up watching Grandma and trying to stay out of her way, which seems the only way my eyes and mind are useful.
　　There we are, lost in the tomato vines（藤）. Grandma’s eyes are always knowing, and they are no different in the vegetable garden. From afar she spots (notice) what looks like a ripe tomato. As she walks toward the garden, she evaluates the tomato for a second time, but from a different angle. I already know it will end up in the basket with the pile of others Grandma has carefully chosen. However, Grandma acts as if she needs a final look to be sure. She calls me to her side, kneels beside the vine while enjoying the warmth of the fading sunlight on her face, and grasps the tomato in her hand. She turns each round, red ball toward the sunlight before disconnecting it from the vine with a half-hearted smile.
　　She then looks at me. I nod my head and smile. Grandma assumes I smile in agreement with her tomato selection. I know I smile, instead, at her.
