Introduction Around the world, people enjoy different kinds of boat races. People race dragon boats in many places. The racers use paddles to make the boats go faster. In cold places, people race ice boats. The wind pushes the boats across frozen lakes and rivers. In India you can watch snake boat races. Over 100 rowers sit in one boat and row as fast as they can. How do these different race boats work? Let's find out! People in Hong Kong, China, have dragon boat races every year in June. paddles Chinese dragon boats

在世界各地,人们喜欢各种各样的赛艇比赛。 人们在许多地方赛龙舟。 选手们用桨使船走得更快。 在寒冷的地方,人们用冰船比赛。 风把船推过结冰的湖泊和河流。 在印度,你可以观看蛇船比赛。 100多名划手坐在一艘船上,尽可能快地划桨。 这些不同的赛艇是如何工作的? 让我们一探究竟吧!在中国香港,人们每年六月都会举行龙舟比赛。 划着中国的龙舟

CHAPTER 1 Dragon Boats Dragon boat races began in China over 2,000 years ago. Now more than 50 million people all over the world race the boats. Before the race, artists paint the boats to look like dragons. Then, they paint on the eyes. The eyes "wake up the dragon." SWEET TREATS People eat sweet rice cakes at the dragon boat races in China. These dragon boats are ready to race. These racers practice for a dragon boat race in China. Why do the boats look like dragons? In China a dragon means that something is powerful. There are 20 to 40 racers in each dragon boat. When the race begins, a drummer on each boat makes a beat. The drum helps the racers paddle together. They paddle 60 to 85 times every minute. beat: a sound that repeats

第一章龙舟龙舟比赛始于2000多年前的中国。 现在,全世界有超过5000万人参加帆船比赛。 在比赛之前,艺术家们把船涂成龙的样子。 然后,他们在眼睛上作画。 眼睛“唤醒龙”。 在中国,人们在赛龙舟时吃甜年糕。 这些龙舟已经准备好比赛了。 在中国,这些赛手正在为龙舟比赛练习。 为什么这些船看起来像龙? 在中国,龙意味着某种东西很强大。 每条龙舟上有20到40名选手。 比赛开始时,每艘船上都有鼓手打鼓。 鼓帮助选手们一起划桨。 它们每分钟划60到85次。 节拍:重复的声音

Why are dragon boats fast? Dragon boats are not heavy. They are light in weight. This makes them go fast. Dragon boats have low sides. Boats with low sides float high in the water. This also makes them go fast. It takes less work to move a dragon boat. DRAGON PARADE The city of Boston, in Massachusetts, has a Hong Kong Dragon Boat Festival every year. People march, or walk, in the parade with dragons. Racers must work together to win a race. Racers push paddles in the water to make the boat's speed fast or slow. If paddles are too big or too small, they are hard to move in the water. It is harder to move a large paddle through the water. A smaller paddle is easier to move. It can move faster through the water. push: to move forward

为什么龙舟快? 龙舟不重。 它们的重量很轻。这让它们跑得很快。 龙舟有低边。 侧低的船在水里浮得高。 这也使它们跑得快。 移动龙舟需要更少的工作。 在马萨诸塞州的波士顿市,每年都会有一个香港端午节。 人们挽着龙在游行队伍中行进。 选手们必须齐心协力才能赢得比赛。 选手在水中推桨,使船的速度快或慢。 如果桨太大或太小,就很难在水中移动。 在水中移动大桨是比较困难的。 较小的桨更容易移动。 它可以在水中移动得更快。 推:向前推进

CHAPTER 2 Ice Boats People have been ice boating for 4,000 years. People used ice boats in the winter. They used them to move foods and other things. Today ice boating is just a fun sport. Racers in boats with sails glide over the ice. Language DETECTIVE Clue: The word them is an object pronoun. Here, them takes the place of ice boats. What does them take the place of on page 6? This ice boat race is in Sandusky, Ohio. sails STOPPING THE BOAT Ice boats don't have brakes to make them stop. They are not like bicycles or cars. The ice boat racer stops the boat by moving the front of the boat into the wind. Ice boats are powered by the wind. Ice boat racers turn the sails to get wind inside them. Then the wind pushes the boat. Ice boaters can use the wind to turn, or steer, the boat. When the wind moves a different way, the ice boat racer turns the sails the same way.

第二章冰船人们划冰船已有四千年的历史了。 人们在冬天用冰船。 他们用它们来移动食物和其他东西。 如今,划冰船只是一项有趣的运动。 选手们乘着帆船在冰面上滑行。 语言侦探线索:单词them是宾语代词。 在这里,它们代替了冰船。 它们在第六页上取代了什么? 这场冰船比赛在俄亥俄州的桑达斯基举行。 船帆让船停下来冰船没有刹车让它们停下来。 它们不像自行车或汽车。 冰上赛艇选手通过让船的前部迎风而停船。 冰船是由风驱动的。 冰船比赛选手转动船帆,让风进入船内。 然后风推动着船。 划冰船的人可以利用风来转向或操纵船。 当风向不同时,冰船赛手将帆转向相同的方向。
