Whether you like it or not, that’s your 1 on Earth, right You may 2 : Do I weigh the same on other planets Before exploring the answer to this, it’s important to understand the 3 between weight and mass (质量). The two seem to be the 4 when we use them in our daily conversation. But to a physicist, they are 5 different things. The mass of a body is a measure (测量) of how 6 matter it holds. Your mass does not change with 7 . If you 8 on the moon, there will be no change in your size or shape. That means your mass 9 the same. Your mass doesn’t change on other planets, 10 , but the gravity (重力) and size of those planets affect how much you weigh. Your weight on any planet is a result of your mass, the gravity of the planet and the distance (距离) you are from the center of the planet. Your weight is a measure of the pull of gravity between you and the planet you are standing on. The 11 the gravity is, the higher your weight is. Astronauts may not weigh anything in space and can move around without touching anything 12 , because there is no gravity to 13 them down. As a result, there is no weight. How much gravity the planet has 14 the size of the planet. A small planet has less gravity and a larger planet has more gravity. If you were to stand on a more massive (巨大的) planet such as Jupiter (木星), you would 15 more; if you were to stand on a less massive planet such as Mars, you would weigh less. 1．A．light B．flight C．weight D．sight 2．A．repeat B．reflect C．reply D．wonder 3．A．role B．size C．patience D．difference 4．A．same B．name C．time D．home 5．A．slowly B．completely C．easily D．cheaply 6．A．heavy B．many C．long D．much 7．A．temperatures B．weather C．planets D．vacations 8．A．compete B．land C．reach D．control 9．A．remains B．changes C．produces D．develops 10．A．too B．instead C．either D．only 11．A．earlier B．later C．taller D．higher 12．A．freely B．quietly C．safely D．certainly 13．A．push B．pull C．blow D．create 14．A．focuses on B．turns on C．depends on D．gets on 15．A．fight B．weigh C．get D．increase 二、阅读理解（共20小题，每小题2分，满分40分） 第一节（共15小题，每小题2分，满分3 ... ...
