第二部分 重难题型练 题型二 完成句子型阅读 类别一 事物介绍（10年6考） 贵州英语RJ 英语 1 Passage 1（2023遵义汇川区五模） Did you know magnets（磁铁） are all around you? Magnets help you do wonderful things! Keep reading! See if you think magnets have surprising uses. Look closely and you will see. Magnets can be found in a fridge. The magnets attract（吸引） or pull the metal to make the door closed. Do you know how? A magnet pulls things made of metals called iron and steel. But it will not pull other things, such as a wooden pencil, a gold ring or a plastic toy, which means it does not attract all. 2 Magnets can pull some things to them. Why is this true? The two ends of a magnet are its poles（磁极）. Every magnet has a north pole and a south pole. Have you ever played with trains that have magnets? Sometimes, you try to put two train cars together, but they push away from each other. Then you turn one of the cars around. The two cars attract each other rapidly. When the train cars push away, two of the same poles are facing each other. However, if you put the north and south poles together, they will be together at once. 3 Scientists are using magnets in new ways. There is a new train that uses powerful magnets to travel more quickly. Magnets lift the train above the track（轨道） and push the train forward. The train appears to be moving as fast as wind! They are much faster than the trains we know. Besides, in medicine, the powerful magnets are used to help patients produce heat to kill cancer cells（癌细胞） without harming their body. The powerful magnets can also be seen in many fields, like space, industry, and teaching. So they play an important role in our life. 4 1.The door of a fridge can be closed because there are _________ in it. magnets 2.A magnet has __________ that can pull some things to it. two poles 【解析】 根据第三段前面四句可知，磁铁的两端是它的磁极，可以把一些东西拉向磁铁，每个磁铁都有一个南磁极和北磁极。也就是说磁极能吸引物体。 5 3.When you put two train cars with the same poles facing each other, they will ___________. push away 4.The last paragraph m
