题目内容
1.A telescope (望远镜),called Gaia,is being designed by astronomers in Europe,and it couldn't be more different from Pan-STARRS,which is another telescope being designed.While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth,Gaia will be looking at our entire galaxy (银河系).Gaia is designed to draw a map of the Milky Way,our home galaxy.Just as a map of your town gives you a picture of where things are located,Gaia's map of the galaxy will tell astronomers where the stars are.Over five years,Gaia will observe (观察) about a billion stars and other objects in our galaxy.Each object will be observed about 70times.
Gaia will be sent into space connected to a rocket.It contains two telescopes,each focused at a different angle (角度).These two telescopes act like Gaia's"eyes".The reason why humans can see things in 3D is that we have two eyes focused on the same object,at slightly different angles.By using two telescopes like eyes,Gaia can produce the first 3D map of the positions of the stars it views.
Gaia,which is to be sent into space in 2011,will be a powerful telescope.If you were to use it on Earth,for example,you could stand 600miles away from your best friends and still get a clear picture of their hair.
Gaia is one of more than a dozen telescopes being designed by scientists right now.The next generation of telescopes will reveal new parts of our universe that will seem surprising.The universe,with all its planets,stars and other strange objects,is a puzzle with pieces that we can see by using powerful telescopes.
17.How many different angles can Gaia focus at each time?A
A.2.
B.3.
C.4.
D.5.
18.The map to be drawn by GaiaD.
A.can show every building on Earth
B.can show you where your town is
C.will just show the stars around Earth
D.will show where the stars are in our home galaxy
19.What's Paragraph 4mainly about?C
A.What Gaia will do in space.
B.When Gaia will start to work.
C.How powerful Gaia will be.
D.What Gaia will do to Earth.
20.The underlined sentence in the last paragraph suggests that the next generation of telescopesD.
A.seem very surprising to scientists
B.will not be put into use in a short time
C.will just look at new things in universe
D.will be more powerful than the old generations.
分析 本文是科普知识类说明文.介绍了一个名为Gaia的天文望远镜,并告诉人们新一代望远镜的功能将会更先进更强大.
解答 ADCD
17.A 细节理解题.根据文章第三段中的"It contains two telescopes,each focused at a different angle (角度)."可知,Gaia有两个望远镜,每个望远镜都有自己的观测角度.故选A.
18.D 细节理解题.根据文章第二段中的"Gaia is designed to draw a map of the Milky Way,our home galaxy."和"Gaia's map of the galaxy will tell astronomers where the stars are."可知,Gaia是用来绘制银河系的示意图,这个示意图会告诉天文学家们(银河系中)星星的位置.故选D.
19.C 段落大意题.根据文章第四段中的第一句话"Gaia,which is to be sent into space in 2011,will be a powerful telescope."可知,本段主要讲Gaia的能力.C项表述与原文相符.
20.D 句意理解题.画线部分句意为:下一代望远镜将会发现宇宙令人惊奇的新的部分.由此可以判断,新一代望远镜的功能将会更先进.故选D.
点评 做阅读时经常犯错的主要原因是,仅凭读过文章后残留在脑海中的一丝印象来勾选答案,这样便很容易掉入出题人故意设布下的题目陷阱.所谓阅读理解,对于题目的理解一定要忠实于原文,因此,每一道题都应该与原文作全面的对比与核查,再得出答案.也就是说,阅读理解的每一道题目,在原文都应该有明确的出处,我们把这一出处叫做原文相关句,(1)排除与原文相关句主题不一致的选项(2)排除与原文相关句态度相反的选项 (3)排除用于过于极端或负面的选项(4)注意结合文章主旨和主题去排除.
