The world is becoming more and more convenient. If you don’t have enough time to go to a store, you can go shopping online. You can find almost everything you need on the Internet these days. In Japan, it usually only takes one or two days for your purchase to arrive in the mail. It can take much longer in North America, so one big online shopping company is developing helicopter drones to deliver small packages to your door. According to the company, these helicopters will bring your purchase to your house in 30 minutes! Doesn’t it sound like science fiction? (by Professor Douglas Jarrell)

Here are two stories about food from different readers.

Reader 1:　While I was walking on a hot day this summer, I saw a crow fly past and drop something white on the road. I went to see what it was. To my　surprise it was a big rice ball. That day was too hot to have lunch outside, so I wonder where the crow got the rice ball.

Reader 2: I was working in my field and got wet in the rain. I went back home in my wet clothes and took a shower. Then I ate a quarter of a watermelon that I got from a relative. It was very sweet. Fortunately, it didn’t spoil my dinner. (edited by Professor Douglas Jarrell)
