Riding Sound Waves

驾驭声波

1 Screeeeeeeeeech! The Newburg Elementary school bus came to a sudden stop. Pablo and Violet lunged forward. "I thought we'd never get here," Pablo moaned as he stretched his arms overhead. The two best friends unfastened their seat belts and looked out the window. Cars, buses, and taxis honked as they zoomed through the streets. People scurried down steps to catch the subway. The smell of hot dogs started to fill the bus. They had finally arrived in the city. Next stop, the City Science Museum!

1 Screeeeeeeeeech !纽堡小学的校车突然停下来。 巴勃罗和维奥莱特向前冲去。 “我以为我们永远也到不了这里了，”巴勃罗一边呻吟，一边把双臂伸到头顶。 两个最好的朋友解开安全带，看着窗外。 汽车、公共汽车和出租车在街道上呼啸而过。 人们匆匆走下台阶去赶地铁。 热狗的味道开始充满了公共汽车。 他们终于到达了这个城市。 下一站，市科学博物馆！

"Can we get off yet?" Violet bounced in her seat. "Hopefully," said Pablo. "I haven't been here since last year." "Me neither. Remember how we learned about viruses? And how fast they can travel around the

“我们可以下车了吗？”维奥莱特在座位上跳来跳去。 “希望如此。”巴勃罗说。“从去年起我就没来过这里。” “我也没有。还记得我们是怎么了解病毒的吗？ 以及它们绕地球运动的速度

world?" asked Violet. "Yeah," said Pablo. "I wonder what we'll get to see this year." Pablo and Violet weren't the only ones who were excited. The bus hummed with the voices of Mr. Eng's third-grade class. This was the first field trip of the year, and everyone had been on the bus for more than an hour. Mr. Eng stood up from the first row and raised his hand to quiet everyone. "Okay, class," he began. "Time to buddy up. Remember the double line we practiced?" "Yes, Mr. Eng!" answered the class. Pablo and Violet were always field trip buddies. In fact, they did everything together. At recess, they either played soccer or double Dutch. And they always shared a sweet, juicy pickle from the Newburg Corner Store on their walk home from school. Recently, Pablo had started helping Violet learn Spanish. And they both loved everything about science. Pablo dreamt of being an astronaut and traveling through space. Violet

维奥莱特问。“是的，”巴勃罗说。 “我想知道今年我们会看到什么。” 巴勃罗和维奥莱特不是唯一兴奋的人。 巴士上嗡嗡作响的是伍启芳所在的三年级班级的声音。 这是今年的第一次实地考察，每个人都在车上待了一个多小时。 伍启芳从第一排站起来，举起手让大家安静下来。 “好了，同学们，”他开始说。“是时候结盟了。 还记得我们练习过的双线吗？”“是的，英先生！”全班同学回答。 巴勃罗和维奥莱特一直是野外旅行伙伴。 事实上，他们做任何事都在一起。 课间休息时，他们要么踢足球，要么打荷兰语。 在放学回家的路上，他们总是一起吃纽堡街角商店买的又甜又多汁的泡菜。 最近，巴勃罗开始帮助维奥莱特学习西班牙语。 他们都热爱科学。 巴勃罗梦想成为一名宇航员，在太空中旅行。 紫

was determined to become a scientist and cure as many diseases as possible. "Listo?" said Violet. "Are you ready?" "Muy bien!" replied Pablo. The Spanish lessons were working. He grabbed his best friend's hand, and they peeled their legs from the sticky seats. "Come on, Henry!" Violet called toward the back of the bus. A boy wearing a tight-fitting black-and-green superhero costume sat in the last row. Two blue eyes gazed over the seats from behind a silver mask. "New costume?" Pablo asked with a smile as Henry made his way to the front. "Yeah!" replied Henry. "My other one got a hole in the armpit." There was an odd number of students in the class, so Mr. Eng added Henry to Violet and Pablo's group. Pablo always tried to be nice to Henry, who was a little different from other kids. Sometimes he would throw tantrums for no reason at all, especially during gym or recess. And he could never sit still and pay attention in class. But

决心成为一名科学家，尽可能多地治愈疾病。 “里斯托？”维奥莱特说。“你准备好了吗？”“再见！”巴勃罗回答。 西班牙语课起作用了。 他抓住他最好的朋友的手，他们把腿从黏糊糊的座位上拉开。 “加油，亨利！”维奥莱特朝汽车后面喊道。 一个穿着紧身黑绿超级英雄服装的男孩坐在最后一排。 两个蓝色的眼睛从一个银色的面具后面盯着座位。 “新服装吧?”巴勃罗微笑着问道，这时亨利朝前面走去。 “是啊！”亨利回答。“我的另一只腋窝破了个洞。” 班上的学生人数是奇数，所以英格先生把亨利加入了维奥莱特和帕布罗的小组。 巴勃罗总是尽量对亨利好，亨利和其他孩子有点不同。 有时他会无缘无故地发脾气，尤其是在健身房或课间休息的时候。 在课堂上，他从来都不能安静地坐着，集中注意力。 但

Pablo knew what it was like to be different. He had felt different from his classmates when he'd first arrived in Newburg from Puerto Rico. Luckily, he'd met Violet. She thought his differences were cool. "It's time to take off your mask now," Mr. Eng said to Henry as they hopped off the bus. Henry held the sides of his mask with both hands. Mr. Eng knelt down. "I know you like wearing your mask. But the rules for entering the museum

巴勃罗知道与众不同是什么感觉。 当他第一次从波多黎各来到纽堡时，他觉得自己和同学们不一样。 幸运的是，他遇到了维奥莱特。她认为他的不同很酷。 “现在该摘下你的口罩了，”下车时，伍启芳对亨利说。 亨利用双手抓着面具的两边。 伍启芳跪了下来。“我知道你喜欢戴面具。 但是进入博物馆的规则
