课件14张PPT。Unit 3 Inventors and inventions 单 元 目 标 锁 定话 题 背 景 链 接Albert Einstein In the year 1905, Albert Einstein published some important papers in a German scientific magazine.They included one of the most important scientific documents in history.It was filled with mathematics.It explained what came to be called his“ Special Theory of Relativity”. Ten years later he expanded it to“ General Theory of Relativity”． Albert Einstein's theories of relativity are about the basic ideas we use to describe natural happenings.They are about time, space, mass, movement, and gravity. Albert Einstein was born in Ulm, Germany, in 1879.His father owned a factory that made electrical devices.His mother enjoyed music and books.His parents were Jewish but they did not observe many of the religion's rules.Albert was a quiet child who spent much of his time alone.He was slow to talk and had difficulty learning to read.When Albert was five years old, his father gave him a compass.The child was filled with wonder when he discovered that the compass needle always pointed in the same direction—to the north.He asked his father and his uncle what caused the needle to move. Their answers about magnetism and gravity were difficult for the boy to understand.Yet he spent a lot of time thinking about them.He said later that he felt something hidden had to be behind things.Albert did not like school.Students could not ask questions.Albert said he felt as if he were in prison.One story says Albert told his uncle Jacob how much he hated school，especially mathematics.His uncle told him to solve mathematical problems by pretending to be a policeman.“ You are looking for someone，” he said，“ but you do not know who.Call him X．Find him by using the mathematical tools of algebra and geometry.” 文章大意：本文是一篇记叙文。主要向我们叙述了爱因斯坦的一些个人情况及其父母的情况，文中末段提到了爱因斯坦的叔叔在爱因斯坦由厌恶数学到热爱数学的变化中起了关键作用。1．When the General Theory of Relativity was put forward，Einstein was _____ years old. A．39 B．26 C．36 D．42 解析：推理判断题。根据文章第一段最后一句话可以得知，爱因斯坦是在从1905年算起的十年后提出了广义相对论，即1915年，再结合第三段提到的信息“爱因斯坦出生于1879年”可以得知，C项为正确答案。C2．What can we know from the third and fourth paragraph？_____ A．Einstein's father enjoyed music and books. B．Einstein's family observed all the religion's rules. C．Einstein's father ran a plant making electrical equipment. D．Einstein was quiet but talkative when he was young. 解析：细节理解题。根据文中第三段的第二句话“His father owned a factory that made electrical devices.”可以得知，爱因斯坦的父亲开办了一家生产电器产品的工厂。C项所述符合题意。误解分析：文中第三段提到爱因斯坦的妈妈喜欢音乐和读书，故A项错误；第三段提到爱因斯坦的父母是犹太人，但并不是遵守所有的教规，故B项错误；第四段提到爱因斯坦喜欢安静和独处，言语迟缓，故D项错误。C3．What made Einstein curiou ... ...
