阅读下列短文，然后根据短文的内容从每小题的四个选择项中选出最佳的一项。 The sun is shining down on an August day. It's one of those terribly hot days. But, I'm smiling. My brother Doug and I are in an open field getting ready to fire our latest model rockets（火箭）. We’ve been getting them by mail order for the past couple of months. Even our mailman is excited. He's here to deliver the packages and will even stay while we open the latest box. Doug and I are trying to catch grasshoppers（蚱蜢）, because this new model has a capsule(弹射座舱）in the top and we need a passenger， preferably alive. What will the grasshopper think about rocketing into the summer sky? We wonder. The rocket shoots up into the blue sky. A deep sound is heard as the capsule is thrown off. We keep watching. As the capsule begins its falling down to earth, we run after it, laughing. Doug gets there first and holds up the capsule. “Looks like it's still alive!” he shouts. I catch up and,bending at the knees, examine the grasshopper inside. I can't tell if it's been shocked by the experience or not, although I imagine it has. “That's the way, man!” My brother and I are smiling from ear to ear, arms around each other's shoulders. “Shall we do it again, Doug?” “Are you joking, man?!” We both run back to the rocket.
