;A lot of people are interested in astronomy and some of them have made great progress in this field.But what do you know about it? Astronomy is the oldest science known to man.;Each new tool added to the field of astronomy，and it helped man reach out into space.Until there were telescopes(望远镜)，man knew little about the moon.They did not know that the planet called Saturn(土星) had rings around it.Their sight was so limited that they could not see all the planets.In the early 1700s，people thought there were only six planets. Before the spectroscope(分光镜) appeared，man did not know what kinds of gases are in the sun or other stars.Without the radio telescope(电望远镜) we did not know that radio noises come from far out in space. Today，astronomy is a growing science.We have learned more in the last fifty years than in the whole history of astronomy.;根据上文完成下列各题 1.What is the oldest science known to man according to the passage? ______________ 2.What does the underlined word “it”(Line 5，Paragraph 4) probably refer to? _______ 3.What does the passage mainly tell us? __________________________________________________________________________________________________________________________;基础自测　;;1. n.天文学 2. n.系统；体系；制度 3. n.宗教；宗教信仰 adj.宗教上的；信奉宗教的；虔诚的 4. adj.猛烈的；激烈的；强暴的 n.暴力；暴行 5. n.大气层；气氛 6. prep.与……不同；不像;7. adj.基本的；基础的 8. adj.有害的 n. vt.损害；危害 9. vi. vt.乘；增加 10. vi.生存；存在 11. adv.因此；于是 12. vt. vi.(使)迷惑；(使)为难 n.谜；难题;Ⅱ.重点短语;Ⅲ.重点句式;Others， ，were able to live on land as well as in the water. 另一些，被称作两栖动物，既能生活在水中，也能生活在陆地上。;So on the earth for millions of years to come will depend on whether this problem can be solved. 所以在未来的数百万年中，生命能否在地球上延续下去将取决于这个问题能否得到解决。;;Ⅰ.根据课文内容
