阅读理解 A From far out in space, Earth looks like a blue ball. Since water covers three-fourths of the Earths surface, blue is the color we see most. The continents look brown, like small islands floating in the huge, blue sea. White clouds cover around the Earth like a light blanket. The Earth is shaped like a sphere, or a ball. It is 25,000 miles around! It would take more than a year to walk around the whole planet. A spaceship can fly around the widest part of the sphere in only 90 minutes. Even though spaceships have traveled to the Moon, people cannot visit the Moon without special suits. The Moon has no air or water. Plants and animals cant live there either. Astronauts first landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, which scientists are still studying. There are holes, or craters, all over the Moons surface. Scientists believe that meteorites(陨石 smashed into the Moon millions of years ago and formed the craters. The Sun is the closest star to Earth. A star is a hot ball of burning gas. The Sun looks very big because it is so close. But the Sun is just a medium-sized star. Billions of far- away stars are much bigger than our Sun. The burning gases from the Sun are so hot that they warm the Earth from 93 million miles away! Even though the Sun is always shining, the night here on Earth is dark. Thats because the Earth rotates, or turns around, every 24 hours. During the day, the Earth faces the Sun. Then we see light.

She is best known for her role in helping the Lewis and Clark expedition(远征. She and her husband were guides from the Great Plains to the Pacific Ocean and back. Sacagawea was taken away from her Shoshone village by Hidatsa Indians when she was 12 years old. And she was immediately sold into slavery. She was then sold to a French hunter by the name of Toussaint Charbonneau. The pair became married and had a son named Jean-Baptiste. Although there are different opinions concerning how important Sacagawea was to the Lewis and Clark expedition, she did serve as the interpreter(口译员 and negotiator to the Shoshone tribe ( 部落 that was led by her brother Cameahwait. She helped them get basic supplies and horses while she carried her baby on her back. Besides, Sacagawea helped recognize edible( 可食的 plants and herbs and prevented unfriendly relations with other tribes simply by being with the expedition. She was even more important on the return trip because she was familiar with the areas in which they were traveling and was able to guide the expedition back safely. Lewis and Clark received credit for discovering hundreds of animals and plants that Sacagawea had probably seen for years. Although she received no payment for her help, her husband was rewarded with cash and land. Six years after the journey, Sacagawea died after giving birth to her daughter Lisette. William Clark raised both of her children, but there are no records of Lisette. To this day, there are no reliable pictures or drawings of Sacagawea.
