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.

Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.

Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
